Percutaneous PVL closure has emerged as a therapeutic strategy for addressing this issue, but data for transcatheter PVL repair after TAVR remains limited.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is a single center retrospective review of PVL closure after TAVR. Patients with balloon\u2010expandable or self\u2010expanding prostheses were included. Baseline patient demographics, procedural characteristics, complications, and clinical outcomes were reviewed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 18 patients with clinically significant PVL after TAVR referred for PVL closure were identified during the study period. Procedural success resulting in successful transcatheter occluder plug delivery was 78% (14 cases). Balloon postdilatation (2\/4) and valve\u2010in\u2010valve (2\/4) were used effectively in the remaining patients after an unsuccessful PVL closure attempt. PVL grading by echocardiography decreased from moderate or severe to\u2009&lt;\u2009moderate in 13 patients (72%). Adverse events including cardiac tamponade and acute kidney injury occurred in 1 case each. One\u2010month all\u2010cause mortality was 11%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In selected patients, percutaneous PVL repair following TAVR is feasible and effective for both balloon\u2010expandable and self\u2010expanding prostheses. Most patients undergoing PVL closure after TAVR require a single occluder plug placement for reduction in PVL to mild or less.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.27224","type":"journal-article","created":{"date-parts":[[2017,8,2]],"date-time":"2017-08-02T09:39:10Z","timestamp":1501666750000},"page":"870-877","source":"Crossref","is-referenced-by-count":23,"title":["Techniques
