Response to Letter Regarding Article, “Postprocedural Aortic Regurgitation in Balloon-Expandable and Self-Expandable Transcatheter Aortic Valve Replacement Procedures: Analysis of Predictors and Impact on Long-Term Mortality: Insights From the FRANCE2 Registry”

We thank Drs Iqbal and Serruys for their interesting comments on our study.1 Transcatheter aortic valve replacement is a very good alternative to conventional surgical replacement in patients with aortic stenosis at increased risk for surgery.2,3 As efficient as it is, transcatheter aortic valve replacement has important limitations, including postprocedural aortic regurgitation (AR). Our study was designed to (1) describe the rate of postprocedural AR evaluated at discharge in a large series of consecutive patients treated with balloon-expandable (BE) and self-expandable devices, (2) analyze the predictors of postprocedural ARs in the overall population for each device, and (3) analyze the impact of postprocedural ARs on clinical outcome.The results of our study1 and others2 demonstrate clearly that postprocedural AR≥moderate as evaluated by echocardiography at discharge is frequent (15%) and is an independent predictor of long-term mortality. Our study demonstrates also that the clinical significance of a postprocedural AR≥moderate is …
