Transcatheter aortic valve implantation (TAVI) is a worldwide accepted alternative for treating patients at intermediate or high risk for surgery. In recent years, the rate of complications has markedly decreased except for new-onset atrioventricular and intraventricular conduction block that remains the most common complication after TAVI. Although procedural, clinical, and electrocardiographic predisposing factors have been identified as predictors of conduction disturbances, new strategies are needed to avoid such complications, particularly in the current TAVI era that is moving quickly toward the percutaneous treatment of low-risk patients. In this article, we will review the incidence, predictive factors, and clinical implications of conduction disturbances after TAVI.

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 ...

The aims of the present study were to investigate the incidence and characteristics of conduction disorders (CDs) after transcatheter aortic valve implantation (TAVI), to analyze the predictors of permanent pacemaker (PPM) implantation, and to evaluate the outcomes of CDs over time. In particular, we sought to investigate whether the depth of deployment and other technical aspects of valve implantation might predict the need for PPM implantation after TAVI. TAVI has been reported to favor the onset or worsening of CDs often requiring PPM implantation. A total of 70 patients with aortic stenosis due to dystrophic calcification underwent TAVI with third-generation CoreValve Revalving System from May 2007 to April 2009. We collected electrocardiograms at baseline, during TAVI, during hospitalization and at the 1-, 3-, 6-, and 12-month follow-up visits thereafter. The clinical, anatomic, and procedural variables were tested to identify the predictors of PPM implantation. The PPM dependency at follow-up was analyzed. Six patients were excluded from the analysis because of a pre-existing PPM. Of the 64 patients, 32 (50%) had one or more atrioventricular-intraventricular CDs at baseline. TAVI induced a worsening in the CDs in 49 (77%) of the 64 patients, with 25 (39%) requiring in-hospital PPM implantation. On multivariate analysis, the independent predictors of PPM implantation were the depth of the prosthesis implantation (p ؍ 0.039) and the pre-existing right bundle branch block (p ؍ 0.046). A trend in the recovery of the CDs over time was recorded, although 2 patients required PPM implantation 1 month after discharge for late complete atrioventricular block. In conclusion, TAVI often induces or worsens CDs, requiring PPM in more than one third of patients, although a trend in the recovery of CDs during the midterm was recorded. The independent predictors of PPM implantation were the depth of prosthesis implantation and pre-existing right bundle branch block.

Objectives: This study sought to evaluate the impact of prosthesis-patient mismatch (PPM) on the risk of early-term mortality after transcatheter aortic valve implantation (TAVI). Methods: Databases (Medical Literature Analysis and Retrieval System Online [MEDLINE], Excerpta Medica dataBASE [EMBASE], Cochrane Controlled Trials Register [CENTRAL/CCTR], ClinicalTrials. gov, Scientific Electronic Library Online [SciELO], Latin American and Caribbean Literature on Health Sciences [LILACS], and Google Scholar) were searched for studies published until February 2019. PPM after TAVI was defined as moderate if the indexed effective orifice area (iEOA) was between 0.85 cm 2 /m 2 and 0.65 cm 2 /m 2 and as severe if iEOA ≤ 0.65 cm 2 /m 2. Results: The search yielded 1,092 studies for inclusion. Of these, 18 articles were analyzed, and their data extracted. The total number of patients included who underwent TAVI was 71,106. The incidence of PPM after TAVI was 36.3% (25,846 with PPM and 45,260 without PPM). One-year mortality was not increased in patients with any PPM (odds ratio [OR] 1.021, 95% confidence interval [CI] 0.979-1.065, P=0.338) neither in those with moderate PPM (OR 0.980, 95% CI 0.933-1.029, P=0.423). Severe PPM was separately associated with high risk (OR 1.109, 95% CI 1.041-1.181, P=0.001). Conclusion: The presence of severe PPM after TAVI increased early-term mortality. Although moderate PPM seemed harmless, the findings of this study cannot not rule out the possibility of it being detrimental, since there are other registries that did not address this issue yet.
Predictors for permanent pacing after transcatheter aortic valve implantation

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.

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.

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.
