CONSORT Flow Diagram. A total of 520 patients consented to participate in this study before surgery and were randomized to receive either active tube clearance (n = 257) or standard chest drainage (n = 263). Of these patients, 11 did not receive the allocated intervention, for a cross-over rate of 2.1%. Thirty patients were included in the study despite being screening failures, mostly because of undergoing a minimally invasive procedure (n = 14) or presenting a history of atrial fibrillation (n = 10). Twenty-seven patients did not complete the 30-day follow-up period, for a completion rate of 95%. Of the 100 patients included in the visual inspection of chest tubes patency, 57 were allocated to ATC and 43, to standard drainage.OR, operating room; TAVR, transcatheter aortic valve replacement
