Incidence and short‐term outcomes of surgical bailout after transcatheter mitral valve repair with the MitraClip system

Objectives This study sought to investigate the incidence and outcomes of surgical bailout (SB) after transcatheter mitral valve repair (TMVr) with MitraClip. Background TMVr poses a risk of serious procedural complications, possibly requiring urgent open surgery for SB. However, little is known about the risk of SB cases after TMVr. Methods We retrospectively identified patients who underwent TMVr using the Nationwide Readmissions Database 2014–2017. SB was defined as open thoracotomy for heart and aorta during the same hospitalization. Annual hospital volume was defined as the annual number of TMVr cases in each hospital in each year. Results Among 15,032 eligible patients, SB was required in 214 (1.42%), of whom 134 (62.6%) underwent mitral valve surgery (113 replacements; 21 repairs). The incidence of SB was decreasing significantly over the 4 years (5.26% in 2014; 0.43% in 2017; ptrend
