Objectives Because of its reduced invasiveness, MitraClip (Abbott Vascular, Menlo Park, CA) therapy usually is reserved for patients with extreme left ventricular dysfunction or severe comorbidity contraindicating surgery. The appropriate post-procedural care in this high-risk population is yet to be defined. In this study, the postoperative course of such patients is reported, focusing on early complications and need for intensive care unit (ICU) management. Design, Setting, and Participants A retrospective analysis of patients with severe mitral regurgitation undergoing transcatheter mitral valve repair with the MitraClip system in the authors institution was performed.

Interventions One hundred thirty patients underwent MitraClip implantation between 2008 and 2012. At the end of the procedure, all patients were admitted to the ICU.

Measurements and Main Results Median ICU stay was 0.98 (0.82-1.87) days. Median mechanical ventilation time was 9.5 (6.8-14.1) hours. One hundred one patients (78%) required inotropic support and 13 patients (10%) suffered cardiogenic shock and required intra-aortic balloon pump support. No patient died during the procedure, but 3 patients died in the ICU. Three postoperative course profiles were identified: Fast-track, overnight stay, and critical illness. Twenty-four patients (18.5%) had an uneventful postoperative course, 89 patients (68.5%) suffered minor complications, and 17 patients (13.1%) required intensive care management and organ support. Preoperative serum creatinine (odds ratio [OR] 1.8; p = 0.014), cardiogenic shock (OR 34,8; p = 0.002), ventricular tachycardia (OR 2.8; p = 0.03), and intra procedural inotropes (OR 4; p = 0.001) were correlated with a complicated postoperative course.

Conclusions A large number of patients undergoing MitraClip could be managed with a fast-track ICU course; however, it still is difficult to predict the postoperative course based on preoperative characteristics.
