| Popis: | Background and Hypothesis: Severe aortic valve stenosis is associated with LVH, which has been shown to increase all-cause mortality and lead to conduction abnormalities. Patients undergoing trans-catheter aortic valve replacement (TAVR) have an increased risk for conduction abnormalities and subsequent permanent pacemaker (PPM) implantation. We investigated an association between pre-TAVR LVH by ECG criteria and post-TAVR conduction abnormalities and need for a permanent pacemaker. This relationship has not been studied before. Methods: A retrospective chart review was conducted in 388 consecutive TAVR patients (57.7% females, transfemoral approach in 59.3%, 77.9% with Sapien valve) without pre-TAVR pacemaker. Analyses of variation, chi-square, multi-variate, and logistic regression were used. The study was approved by the institutional IRB. Results: Post-TAVR pacemaker was more commonly needed in patients with baseline QRS >120 msec (35 vs. 11%, p Conclusion: LVH by voltage criteria in TAVR patients is associated with post-TAVR LBBB and post-TAVR high degree AV blocks, which lead to post-TAVR pacemaker placement. Pre-TAVR LVH by ECG criteria may be used to identify high-risk patients in whom extended telemetry monitoring may be warranted. Additional studies investigating this important subject are needed. |
