Predictors for permanent pacing after transcatheter aortic valve implantation
Catheterization and Cardiovascular Interventions, 2010
Background: Transcatheter aortic valve implantation (TAVI) is a new treatment strategy for patients with symptomatic aortic stenosis who are high risk for traditional surgical aortic valve replacement. The incidence of conduction system abnormalities after the procedure is significant. We examine our experience with CoreValve TAVI focusing on electrocardiographic changes found pre-, peri-, and postintervention. Methods: During 2007-08 we undertook 33 cases utilizing the CoreValve revalving system (CoreValve, Paris, France). Assessment of ECGs, with particular reference to the PR and QRS duration, was made daily during each patient's hospital stay. Results: Patients were aged 81.7 6 6.7 years and the majority were male (57%). Baseline cardiac rhythm was sinus (n 5 28, 80%); atrial fibrillation (n 5 6, 18%) or ventricular paced (n 5 1, 3%). Following CoreValve implantation, prolongation of both the PR interval and QRS duration was seen. Preprocedural PR interval was 193.5 6 38.7 ms and QRS interval preprocedure was 115.3 6 24.8 ms. PR interval increased after the procedure by 23.5 6 23.9 ms and peaked at day 4 with a mean increase of 66.1 6 72.7 ms. QRS duration increased by a mean of 30.6 6 26.1 ms postprocedure and remained stable thereafter during the remaining hospital stay. The need for PPM insertion was partially predicted by pre-procedural QRS morphology: patients with pre-existing right bundle branch block had an 83% chance of requiring a permanent pacemaker (P < 0.01 OR 28 95%CI 2.4-326.7); those with LBBB had a 33% chance of requiring a pacemaker (P 5 ns OR 2.3 95%CI 0.2-34.9). Patients undergoing the procedure later in our experience showed a decreased incidence of pacing (P 5 0.046 OR 0.36 95% CI 0.07-1.82). Pre-procedural annulus measurements also predicted the requirement for pacing with larger annulus sizes more likely to require a pacemaker (P 5 0.044 OR 3.3 95% CI 0.63-17.6). The requirement for pacing was not predicted by age, baseline PR interval or gender. Requirement for pacing overall was 32% with an additional 13% having had a pacemaker inserted prior to the TAVI. Conclusion: CoreValve insertion was associated with an increase in PR interval and QRS duration. PR interval continued to rise during admission, peaking on Day 4 post procedure, making a prolonged period of monitoring highly desirable. There was a significant requirement for permanent pacing, which was predicted by pre-procedural QRS morphology, annulus measurement, and the learning curve. V C 2010 Wiley-Liss, Inc.

Background: Conduction disorders requiring permanent pacemaker (PPM) implantation are a known complication of trans-catheter aortic valve implantation (TAVI). Indications for permanent pacing in this setting are still controversial. The study aim was to characterize the natural history of conduction disorders related to TAVI, and to identify predictors for long term pacing dependency. Methods: Consecutive patients who underwent TAVI were included in this prospective observational study. The conduction system was investigated by reviewing 12-lead ECGs during hospitalization and up to 1-year follow-up and by analyzing pacemaker interrogation data. Multivariate analysis was performed in order to identify independent predictors for pacemaker dependency. Results: Of 110 patients included in the analysis, 38 (34.5%) underwent PPM implantation. Of those, 26 (68.4%) had a long-term pacing dependency (required PPM), while 12 (31.6%) did not (notrequired PPM). Logistic regression revealed that baseline RBBB (P = 0.01, OR = 18.0), baseline PR

Permanent pacemaker implantation after transcatheter aortic valve implantation (TAVI) has emerged as a relevant issue, being more frequent than after surgery and the progressive shift towards low-risk patients stressed the importance to reduce the risk of complications that could impact patient’s long-term prognosis. Long-term right ventricular pacing has been related to an increased risk of electromechanical asynchrony, negative left-ventricular remodelling, atrial fibrillation and heart failure, but there is a lack of evidence regarding the prognostic impact on TAVI patients. The aim of this international multicentre study is to assess the impact of right ventricular pacing on prognosis of TAVI patients undergone pacemaker implantation after the procedure due to conduction disorders. All the consecutive patients with severe aortic stenosis treated with TAVI and subsequently underwent pacemaker implantation in each participating centre were enrolled. Patients were divided into two ...
Transcatheter Aortic Valve Implantation and Requirements of Pacing Over Time
Pacing and Clinical Electrophysiology, 2013
Background: A permanent pacemaker (PPM) implantation is common after transcatheter aortic valve implantation (TAVI). We sought to evaluate requirements of pacing and incidence of pacemaker dependency during the first year after TAVI. Methods: From August 2007 until May 2011, 65 patients underwent TAVI with self-expandable prosthesis. Five patients paced at baseline and two procedure-related deaths were excluded. Evaluation of ventricular pacing percentage (VP%) and look for spontaneous rhythm were performed at 3, 6, and 12 months. Results: PPM implantation was required in 19/58 patients (33%). Mean VP% decreased between assessments (59% at 3 months, 48% at 6 months, 50% at 12 months), but overall VP% at 1 year was high (57% ± 43%) and most patients were paced ≥10% of time. A favorable annulus-to-aorta angle was associated with lower pacing requirements (60% of patients paced ≤10% of time vs 10% of patients paced >10% of time presented an angle ≤30 0 , P = 0.039). Pacemaker dependency was established in 27% of patients and could be predicted by the presence of porcelain aorta (odds ratio = 30, confidence interval 95% 1-638, P = 0.029). New postprocedural left bundle branch block (LBBB) had a negative impact on 1-year survival (58% vs 82% in non-LBBB group, P = 0.111). PPM implantation had no impact on 1-year survival. Conclusions: One third of patients required PPM after TAVI and full recovery of advanced conduction abnormalities seems unlikely. Unfavorable aortic root orientation may hinder the deployment of the valve and contribute to the continued impairment of the conduction system. Porcelain aorta was a strong predictor of pacemaker dependency.

Objective: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI) and indications for permanent pacemaker implantation (PPI) were reviewed, which aren't well established in the current guidelines. New left bundle branch block and atrioventricular block are the most common electrocardiographic changes after TAVI. PPI incidence ranges from 9-42% for selfexpandable and 2.5-11.5% for balloon expandable devices. Not only anatomical variations in conduction system have an important role in conduction disorders, but different valve characteristics and their relationship with cardiac structures as well. Previous right bundle branch block has been confirmed as one of the most significant predictors for PPI.

Aortic valve substitution is a standard technique with tolerable risk; nevertheless, the high mortality may be contraindicated. To reduce morbidity and mortality minimally invasive transcatheter aortic valve implantation (TAVI) may be an alternative approach. Although considered secure, after the method complications can occur, presenting as new-onset persistent left bundle branch block and demanding pacemaker implant. To establish how frequent this probability is, a systematic review from PUBMED (philters used were "15 years" and "free full texts") was achieved applying the terms "TAVI", "pacing" and "complications". For supporting literature, the other sources (SCIELO, Google Scholar and MEDLINE) were used and consulted for supporting literature. Catheter aortic prosthesis implantation is an effective modality for patients with high surgical risk and severe aortic stenosis. The review results suggest that the need for a pacemaker a...

Atrioventricular conduction disturbances requiring implantation of permanent pacemaker (PPM) are a common complication following transcatheter aortic valve implantation (TAVI). Previous registry data are conflicting but suggestive of an increased risk in heart failure admissions in the post-TAVI PPM cohort. Given the expanding use of TAVI, the present study evaluates the effects of chronic right ventricular pacing (RV pacing) in post-TAVI patients. This is a single-center study of 672 patients who underwent TAVI from 2011 to 2017 of which 146 underwent PPM. Follow-up 1-year post-TAVI outcome data were available for 55 patients and were analyzed retrospectively. Patients who underwent PPM were more likely to have heart failure admissions (17.1% vs 10.1%; hazard ratio [HR] 1.70; 95% confidence interval [CI] 1.10 to 2.64; p 0.019) and a trend toward increased mortality (21.9% vs 15.4%; HR 1.42; 95% CI 0.99 to 2.05; p 0.062). At 1-year follow-up, 30 of 55 (54.5%) patients demonstrated &...

The objective of this study was to determine the long-term (>1 year) electrocardiographic (ECG) and clinical outcomes of patients without significant changes in their electrocardiogram after transcatheter aortic valve implantation (TAVI; including patients with preexisting ECG abnormalities). Among 772 consecutive patients who underwent TAVI in our institution, 397 patients (51%) without new ECG changes were included. TAVI patients were divided into 2 groups according to the presence of pre-existing ECG-conduction disturbances (ECG-CD: 140 patients, non-ECG-CD: 257 patients). Clinical follow-up (median: 35 [22 to 57] months) was complete in all patients but 5 (1.2%), and ECG data were available in 291 patients (84.3% of patients at risk) at a median of 29 (20 to 50) months. In the non-ECG-CD group, most patients (79.8%) remained without significant ECG changes at follow-up, and 16.9% developed first-degree atrioventricular block and/ or bundle branch block over time. The rate of permanent pacemaker (PPM) implantation at follow-up was 3.5% (1.1%/year) in the non-ECG-CD group versus 15.7% (5.5%/year) in the ECG-CD group (p <0.001). The presence of pre-existing CD was an independent predictor of PPM at follow-up (hazard ratio [HR] 4.67, 95% confidence interval [CI] 2.15 to 10.16, p <0.001). The ECG-CD group exhibited a higher risk of heart failure hospitalization (non-ECG-CD: 25%, ECG-CD: 29%, log-rank p = 0.01), but not mortality (non-ECG-CD: 50%, ECG-CD: 46%, log-rank p = 0.60) at 5-year follow-up. In conclusion, the ECG remained unchanged in most TAVI recipients without new postprocedural CD. Preexisting ECG-CD was associated with an increased risk of PPM and heart failure hospitalization at long-term follow-up. These results provide reassuring data in the era of TAVI expanding toward candidates with a longer life expectancy, and highlight the importance of a closer follow-up of those patients with pre-existing ECG-CDs.
Short-Term Atrioventricular Dysfunction Recovery after Post-TAVI Pacemaker Implantation
Journal of Cardiovascular Development and Disease
Permanent pacemaker implantation (PPI) represents a frequent complication after transcatheter aortic valve implantation (TAVI) due to atrio-ventricular (AV) node injury. Predictors of early AV function recovery were investigated. We analyzed 50 consecutive patients (82 ± 6 years, 58% males, EuroSCORE: 7.8 ± 3.3%, STS mortality score: 5 ± 2.8%). Pacemaker interrogations within 4–6 weeks from PPI were performed to collect data on AV conduction. The most common indication of PPI was persistent third-degree (44%)/high-degree (20%) AV block/atrial fibrillation (AF) with slow ventricular conduction (16%) after TAVI. At follow-up, 13 patients (26%) recovered AV conduction (i.e., sinus rhythm with stable 1:1 AV conduction/AF with a mean ventricular response >50 bpm, associated with a long-term ventricular pacing percentage < 5%). At multivariate analysis, complete atrio-ventricular block independently predicted pacemaker dependency at follow-up (p = 0.019). Patients with persistent AV...

Transcatheter aortic valve implantation (TAVI) frequently requires postprocedural permanent pacemaker (PPM) implantation. We evaluated clinical and hemodynamic impact of PPM after TAVI. Clinical and echocardiographic data were retrospectively analyzed in 230 consecutive patients who underwent TAVI and echocardiography at baseline and after 6 months. Echocardiographic parameters included left ventricular ejection fraction (LVEF), left ventricular (LV) stroke volume, early mitral velocity/annulus velocity ratio (E/e 0 ), right ventricular index of myocardial performance, systolic pulmonary artery pressure (SPAP), and aortic, mitral, and tricuspid regurgitation grades. Clinical outcomes included 2-year survival and cardiovascular and PPM-related event-free survival. The Medtronic CoreValve and Edwards Sapien prosthesis were used in 201 and 29 patients, respectively. PPM was required in 58 patients (25.4%). Two-year and event-free survival rates were similar between patients with and without PPM. At 6 months, patients with PPM demonstrated attenuated improvement in LVEF (L0.9 -8.7% vs 2.3 -10.8%, respectively, p [ 0.03) and LV stroke volume (L2 -16 vs 4 -10 ml/m 2 , respectively, p [ 0.015), a trend toward smaller reduction in systolic pulmonary artery pressure (L1 -12 vs L6 -10 mm Hg, respectively, p [ 0.09), and deterioration of right ventricular index of myocardial performance (L3 -17% vs 5 -26%, respectively, p [ 0.05). The differences in post-TAVI aortic, mitral, and tricuspid regurgitation grades were insignificant. In conclusion, PPM implantation after TAVI is associated with reduced LVEF and impaired LV unloading. However, this unfavorable hemodynamic response does not affect the 2-year clinical outcome. The maintenance of clinical benefit appears to be driven by TAVI-related recovery of LV and right ventricular performance that mitigates unfavorable impact of PPM. Ó 2014 Elsevier Inc.
