Methods and Results— We performed a multicenter registry of consecutive chronic total occlusion patients treated with BRS (Absorb; Abbott Vascular) and second-generation drug-eluting stents (DES) at 5 institutions. Long-term target-vessel failure (a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-lesion revascularization) was the primary end point. Inverse probability of treatment weight–adjusted Cox regression was used to account for pretreatment differences between the 2 groups. A total of 537 patients (n=153 BRS; n=384 DES) were included. BRS patients were younger and had lower prevalence of comorbidities. Overall mean Japan-Chronic Total Occlusion (J-CTO) score was 1.43±1.16, with no differences between groups. Procedural success was achieved in 99.3% and 96.6% of BRS- and D...

We compiled a multicentre registry of consecutive patients undergoing CTO PCI at 7 centres between January 2009 and April 2017. The primary end point was target-vessel failure (TVF), a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization on follow-up. Overall, 2058 patients were included (patients who underwent CABG, n = 401; CABG-naïve patients, n = 1657). Patients who had undergone CABG were older and had a higher prevalence of comorbidities and higher occlusion complexity (RECHARGE score, 3.6 ± 1.3 vs 1.8 ± ...

Consecutive patients undergoing CTO PCI at 4 centers were included. Baseline SYNTAX score (bSS: low [≤ 22], intermediate [>22 and <33], high [≥33]), residual SYNTAX score (rSS: 0, >0 and ≤8, >8), and SYNTAX revascularization index (SRI: 100 × (bSS-rSS)/bSS: 100%, 50% to 99%, <50%) were calculated. The primary end point was major adverse cardiac events (MACEs; cardiac death, any myocardial infarction, any revascularization) on follow-up. Multivariable Cox regression analysis was conducted to identify predictors of MACEs. Overall, 686 patients were included (low bSS: n = 437; intermediate bSS: n = 187; high bSS: n = 62). Occlusion complexity, crossing strategies, and procedural success rates were similar across groups. The degree of ICR increased with higher bSS categories (rSS was 2.5 ...

There is little evidence on the outcomes of SS for IS-CTO. We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS). Target-vessel failure (TVF) on follow-up was the endpoint of this study, and was defined as a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization. During study period, 422 IS-CTO PCIs were performed, of which 32 (7.6%) were recanalized with SS, usually when conventional approaches failed. The most frequent CTO vessel was the right coronary artery (72%). Mean J-CTO score was 3.1 ± 0.9. SS was antegrade in 53%, and retrograde in 47%. Part of the occluded stent was crushed in 37%, while the whole stent was crushed in 63%. Intravascular imaging was used in 59%. On...

Research paper thumbnail of One Versus 2-stent Strategy for the Treatment of Bifurcation Lesions in the Context of a Coronary Chronic Total Occlusion. A Multicenter Registry

This study compared the procedural and mid-term outcomes of patients with bifurcation lesions in CTO treated with provisional stenting vs 2-stent techniques in a multicenter registry. Between January 2012 and June 2016, 922 CTO were recanalized at the 4 participating centers. Of these, 238 (25.8%) with a bifurcation lesion (side branch ≥ 2mm located proximally, distally, or within the occluded segment) were treated by a simple approach (n=201) or complex strategy (n=37). Propensity score matching was performed to account for selection bias between the 2 groups. Major adverse cardiac events (MACE) consisted of a composite of cardiac death, myocardial infarction, and clinically-driven target lesion revascularization. Angiographic and procedural success were similar in the simple and complex groups (94.5% vs 97.3%; P=.48 and 85.6% vs 81.1%; P=.49). Howeve...

Between April 2005 and August 2011, we recruited 937 consecutive unprotected distal left main patients treated with drug-eluting stents (1-SS, 608 patients; 2-SS, 329 patients). Major adverse cardiovascular events were defined as all-cause death, myocardial infarction, or target lesion revascularization (TLR) during the median follow-up period of 1592 days. Furthermore, the individual components of major adverse cardiovascular events, cardiac death, and stent thrombosis were evaluated. More complex lesions were seen with 2-SS than with 1-SS. Cardiac death occurred more frequently with 1-SS than with 2-SS (propensity score-adjusted hazard ratio, 0.52; 95% confidence interval, 0.29-0.64; P=0.03), whereas TLR occurred more frequently with 2-SS than with 1-SS (propensity score-adjusted hazard ratio, 1.59; 95% confidence interval, 1.15-2.20; P=0.005). TLR was mainly driven by revascularizations after restenosis at the ostial left circumflex artery (propensity score-adjusted hazard ratio, 1.94; 95% confidence interval, 1.33-2.82; P=0.001). However, there were no differences in major adverse cardiovascular events, all-cause death, stent thrombosis, and myocardial infarction. Of the 139 pairs that were propensity score matched, only TLRs were significantly higher in the 2-SS group (hazard ratio, 1.59; 95% confidence interval, 1.00-2.53; P=0.05). The difference between 1-SS and 2-SS in percutaneous coronary intervention for unprotected distal left main disease may be summarized by the high incidence of TLR, mainly because of restenosis at the ostial left circumflex artery in the 2-SS group.

This study aimed to clarify the impact of gender in patients treated with drug-eluting stents (DES) for unprotected left main (ULM) disease. Between April 2002 and August 2011, 1026 consecutive patients (212 women and 814 men) undergoing PCI using first or second generation DES for ULM stenosis were analyzed. Study endpoints included major adverse cardiac events (MACE) defined as composite of all-cause death, myocardial infarction (MI), and target lesion revascularization (TLR). Individual components of MACE and cardiac death were also evaluated. Women had greater comorbidity and more complex lesions, resulting in a higher incidence of cardiac death, TLR and MI {[HR, 1.94 (95% CI, 1.22-3.09, p=0.005)], [HR, 1.31 (95% CI 0.96-1.81), p=0.09] and [HR, 2.04 (95% CI, 0.98-4.25), p=0.06], respectively}. Propensity score matching identified 131 matched pairs. There were no differences in MACE [HR, 1.04 (95% CI, 0.68-1.61, p=0.85)], all-cause death [HR, 0.96 (95% CI, 0.52-1.77), p=0.89] or MI [HR, 0.84 (95% CI, 0.21-3.50, p=0.84)]. However, cardiac death [HR, 2.70 (95% CI, 0.98-7.49, p=0.056] and TLR [HR, 1.62 (95% CI, 0.93-2.84), p=0.09] showed a trend to being higher in women compared to men. In patients with ULM disease, women had greater comorbidity and more complex lesions, resulting in an increased risk of clinical events. However after propensity matching, there was no difference in the occurrence of MACE but cardiac death showed a trend to being higher in women compared to men.

It is unknown whether SB strut dilation is routinely required after single crossover BRS implantation if there is no compromise of the jailed SB. Among 187 bifurcation lesions treated with Absorb BRS, 115 lesions (101 patients) were treated with single crossover BRS implantation. Strut dilation toward SB was considered only when SB was compromised (SB TIMI flow &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 3 or SB ostium &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 75%) after main branch (MB) BRS implantation. Clinical outcomes including cardiac death, follow-up myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and definite scaffold thrombosis (ST) were investigated. The majority of target lesions were in the left anterior descending artery (73.0%) and the rate of true bifurcation lesions was 42.6%. SB strut dilation was performed in only 20% of lesions (n = 23), and intravascular imaging was used in most cases (90.4%). The rates of TLR per lesion at 1-year was 3.1% in MB, and 0% in SB. In all patients, the cumulative rate of cardiac death was 1.1% at 1-year, follow-up MI 2.2%, TVR 3.5%, and definite ST 1.0%. Clinical outcomes were acceptable in bifurcation lesions treated with single crossover BRS implantation without routine SB strut dilation. © 2016 Wiley Periodicals, Inc.

Research paper thumbnail of Update on Coronary Chronic Total Occlusion Percutaneous Coronary Intervention

Interventional Cardiology Clinics, 2016

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved ... more Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved during recent years. High success rates are being achieved by experienced centers and operators, but not at less-experienced centers. Use of CTO crossing algorithms can help improve the success and efficiency of these potentially lengthy procedures. There is a paucity of clinical trial data examining clinical outcomes of CTO PCI, which is critical for further adoption and refinement of the procedure. We provide a detailed overview of the clinical evidence and current available crossing strategies, with emphasis on recent developments and techniques.

OBJETIVO: Avaliar os desfechos hospitalares em pacientes com idade superior a 70 anos submetidos a ICP na era contemporânea. MÉTODO: Entre janeiro de 2005 e junho de 2007, pacientes submetidos a ICP foram incluídos consecutivamente em um registro. Informações referentes a fatores de risco, indicação do exame, detalhes técnicos da ICP e desfechos intra-hospitalares foram prospectivamente coletadas. Os pacientes foram divididos em dois grupos: idade &lt; ou &gt; 70 anos. Para comparação, foram utilizados os testes t de Student e qui-quadrado, para variáveis contínuas e categóricas, respectivamente. Valores de p &lt; 0,05 foram considerados diferença estatisticamente significante. RESULTADOS: Foram incluídos na análise 296 pacientes (186 com &lt; 70 anos e 110 com &gt; 70 anos). Não foi observada diferença em relação às características clínico-angiográficas entre os grupos e o sucesso angiográfico foi semelhante (96,6% vs. 97,1%; p = 0,91). Ocorreu tendência a maior mortalidade (1,81% vs. 0,53%; p = 0,06) e a maior incidência de acidente vascular encefálico (1,81% vs. 0%; p = 0,06) no grupo mais idoso. A incidência de cirurgia de urgência e de complicações vasculares não diferiu entre os grupos. Ocorreu maior incidência de nefropatia induzida pelo contraste no grupo &gt; 70 anos (2,7% vs. 0%; p = 0,02). CONCLUSÃO: Pacientes com idade &gt; 70 anos apresentaram incidência aumentada de nefropatia induzida pelo contraste e tendência a maior mortalidade e a maior ocorrência de acidente vascular encefálico.

To evaluate the mid-term clinical and angiographic outcome of drug-eluting stent (DES) implantation in trifurcation lesions. All complications and major adverse cardiac events, including cardiac death, Q-wave myocardial infarction (MI), target lesion revascularization (TLR), and target vessel revascularization (TVR) were recorded in-hospital and during clinical follow up. A total of 15 consecutive patients undergoing percutaneous coronary intervention with DES in de novo trifurcation lesions were identified. Lesions were located as follows: 13 (86.7%) at the distal left main coronary artery (LMCA) comprising the left anterior descending artery (LAD), the left circumflex artery (LCX) and an intermediate branch; 1 between the LAD, diagonal, and septal branches; and 1 between the LCX, obtuse marginal and posterior lateral branches. Stenting was performed in all 3 branches in 8 patients, in 2 ...

Methods and Results— We performed a multicenter registry of consecutive chronic total occlusion patients treated with BRS (Absorb; Abbott Vascular) and second-generation drug-eluting stents (DES) at 5 institutions. Long-term target-vessel failure (a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-lesion revascularization) was the primary end point. Inverse probability of treatment weight–adjusted Cox regression was used to account for pretreatment differences between the 2 groups. A total of 537 patients (n=153 BRS; n=384 DES) were included. BRS patients were younger and had lower prevalence of comorbidities. Overall mean Japan-Chronic Total Occlusion (J-CTO) score was 1.43±1.16, with no differences between groups.

This study compared the procedural and mid-term outcomes of patients with bifurcation lesions in CTO treated with provisional stenting vs 2-stent techniques in a multicenter registry. Between January 2012 and June 2016, 922 CTO were recanalized at the 4 participating centers. Of these, 238 (25.8%) with a bifurcation lesion (side branch ≥ 2mm located proximally, distally, or within the occluded segment) were treated by a simple approach (n=201) or complex strategy (n=37). Propensity score matching was performed to account for selection bias between the 2 groups. Major adverse cardiac events (MACE) consisted of a composite of cardiac death, myocardial infarction, and clinically-driven target lesion revascularization.

Between April 2005 and August 2011, we recruited 937 consecutive unprotected distal left main patients treated with drug-eluting stents (1-SS, 608 patients; 2-SS, 329 patients). Major adverse cardiovascular events were defined as all-cause death, myocardial infarction, or target lesion revascularization (TLR) during the median follow-up period of 1592 days. Furthermore, the individual components of major adverse cardiovascular events, cardiac death, and stent thrombosis were evaluated. More complex lesions were seen with 2-SS than with 1-SS. Cardiac death occurred more frequently with 1-SS than with 2-SS (propensity score-adjusted hazard ratio, 0.52; 95% confidence interval, 0.29-0.64; P=0.03), whereas TLR occurred more frequently with 2-SS than with 1-SS (propensity score-adjusted hazard ratio, 1.59; 95% confidence interval, 1.15-2.20; P=0.005). TLR was mainly driven by revascularizations after restenosis at the ostial left circumflex artery (propensity score-adjusted hazard ratio, 1.94; 95% confidence interval, 1.33-2.82; P=0.001). However, there were no differences in major adverse cardiovascular events, all-cause death, stent thrombosis, and myocardial infarction. Of the 139 pairs that were propensity score matched, only TLRs were significantly higher in the 2-SS group (hazard ratio, 1.59; 95% confidence interval, 1.00-2.53; P=0.05). The difference between 1-SS and 2-SS in percutaneous coronary intervention for unprotected distal left main disease may be summarized by the high incidence of TLR, mainly because of restenosis at the ostial left circumflex artery in the 2-SS group.

This study aimed to clarify the impact of gender in patients treated with drug-eluting stents (DES) for unprotected left main (ULM) disease. Between April 2002 and August 2011, 1026 consecutive patients (212 women and 814 men) undergoing PCI using first or second generation DES for ULM stenosis were analyzed. Study endpoints included major adverse cardiac events (MACE) defined as composite of all-cause death, myocardial infarction (MI), and target lesion revascularization (TLR). Individual components of MACE and cardiac death were also evaluated. Women had greater comorbidity and more complex lesions, resulting in a higher incidence of cardiac death, TLR and MI {[HR, 1.94 (95% CI, 1.22-3.09, p=0.005)], [HR, 1.31 (95% CI 0.96-1.81), p=0.09] and [HR, 2.04 (95% CI, 0.98-4.25), p=0.06], respectively}. Propensity score matching identified 131 matched pairs. There were no differences in MACE [HR, 1.04 (95% CI, 0.68-1.61, p=0.85)], all-cause death [HR, 0.96 (95% CI, 0.52-1.77), p=0.89] or MI [HR, 0.84 (95% CI, 0.21-3.50, p=0.84)]. However, cardiac death [HR, 2.70 (95% CI, 0.98-7.49, p=0.056] and TLR [HR, 1.62 (95% CI, 0.93-2.84), p=0.09] showed a trend to being higher in women compared to men. In patients with ULM disease, women had greater comorbidity and more complex lesions, resulting in an increased risk of clinical events. However after propensity matching, there was no difference in the occurrence of MACE but cardiac death showed a trend to being higher in women compared to men.

It is unknown whether SB strut dilation is routinely required after single crossover BRS implantation if there is no compromise of the jailed SB. Among 187 bifurcation lesions treated with Absorb BRS, 115 lesions (101 patients) were treated with single crossover BRS implantation. Strut dilation toward SB was considered only when SB was compromised (SB TIMI flow &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 3 or SB ostium &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 75%) after main branch (MB) BRS implantation. Clinical outcomes including cardiac death, follow-up myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and definite scaffold thrombosis (ST) were investigated. The majority of target lesions were in the left anterior descending artery (73.0%) and the rate of true bifurcation lesions was 42.6%. SB strut dilation was performed in only 20% of lesions (n = 23), and intravascular imaging was used in most cases (90.4%). The rates of TLR per lesion at 1-year was 3.1% in MB, and 0% in SB. In all patients, the cumulative rate of cardiac death was 1.1% at 1-year, follow-up MI 2.2%, TVR 3.5%, and definite ST 1.0%. Clinical outcomes were acceptable in bifurcation lesions treated with single crossover BRS implantation without routine SB strut dilation. © 2016 Wiley Periodicals, Inc.

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved ... more Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved during recent years. High success rates are being achieved by experienced centers and operators, but not at less-experienced centers. Use of CTO crossing algorithms can help improve the success and efficiency of these potentially lengthy procedures. There is a paucity of clinical trial data examining clinical outcomes of CTO PCI, which is critical for further adoption and refinement of the procedure. We provide a detailed overview of the clinical evidence and current available crossing strategies, with emphasis on recent developments and techniques.

OBJETIVO: Avaliar os desfechos hospitalares em pacientes com idade superior a 70 anos submetidos a ICP na era contemporânea. MÉTODO: Entre janeiro de 2005 e junho de 2007, pacientes submetidos a ICP foram incluídos consecutivamente em um registro. Informações referentes a fatores de risco, indicação do exame, detalhes técnicos da ICP e desfechos intra-hospitalares foram prospectivamente coletadas. Os pacientes foram divididos em dois grupos: idade &lt; ou &gt; 70 anos. Para comparação, foram utilizados os testes t de Student e qui-quadrado, para variáveis contínuas e categóricas, respectivamente. Valores de p &lt; 0,05 foram considerados diferença estatisticamente significante. RESULTADOS: Foram incluídos na análise 296 pacientes (186 com &lt; 70 anos e 110 com &gt; 70 anos). Não foi observada diferença em relação às características clínico-angiográficas entre os grupos e o sucesso angiográfico foi semelhante (96,6% vs. 97,1%; p = 0,91). Ocorreu tendência a maior mortalidade (1,81% vs. 0,53%; p = 0,06) e a maior incidência de acidente vascular encefálico (1,81% vs. 0%; p = 0,06) no grupo mais idoso. A incidência de cirurgia de urgência e de complicações vasculares não diferiu entre os grupos. Ocorreu maior incidência de nefropatia induzida pelo contraste no grupo &gt; 70 anos (2,7% vs. 0%; p = 0,02). CONCLUSÃO: Pacientes com idade &gt; 70 anos apresentaram incidência aumentada de nefropatia induzida pelo contraste e tendência a maior mortalidade e a maior ocorrência de acidente vascular encefálico.

The patient was treated with low-dose diuretic therapy and ventilatory support. At follow-up echocardiographic evaluation, a progressive improvement of mitral regurgitation and pulmonary artery pressure was observed. The most significant hemodynamic changes occurring during pregnancy are reviewed and discussed in the setting of associated mitral regurgitation.

To evaluate the mid-term clinical and angiographic outcome of drug-eluting stent (DES) implantation in trifurcation lesions. All complications and major adverse cardiac events, including cardiac death, Q-wave myocardial infarction (MI), target lesion revascularization (TLR), and target vessel revascularization (TVR) were recorded in-hospital and during clinical follow up. A total of 15 consecutive patients undergoing percutaneous coronary intervention with DES in de novo trifurcation lesions were identified. Lesions were located as follows: 13 (86.7%) at the distal left main coronary artery (LMCA) comprising the left anterior descending artery (LAD), the left circumflex artery (LCX) and an intermediate branch; 1 between the LAD, diagonal, and septal branches; and 1 between the LCX, obtuse marginal and posterior lateral branches. Stenting was performed in all 3 branches in 8 patients, in 2 ...
