ABSTRACT
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 < .001). There was a significant nonlinear, inverse association of annual hospital volume with the incidence of SB. In-hospital death (15.0 vs. 2.1%; p < .001) and other in-hospital adverse events were significantly more frequent in patients with than without SB, whereas the 30-day readmission rate was similar (13.2 vs. 15.1%; p = .572). After adjustment for patient and hospital characteristics, SB was significantly associated with higher in-hospital mortality (odds ratio = 6.67, 95% confidence interval = 4.35, 10.23, p < .001).CONCLUSIONS:
This study suggests that although the incidence of SB after TMVr is decreasing, SB is required more frequently in lower-volume hospitals and carries high in-hospital mortality. Further efforts are needed to understand the reasons for SB and improve outcomes in patients needing SB.Palavras-chave
