† Some patients received other short, non-CABG procedures in addition to AVR: Perimount: 3 x LAA clip + ablation, 1 x LAA clip, 1 x AMVL decalcification, 1 x septal myotomy; Perceval: 3 x LAA clip, 1 x AMVL decalcification, 1 x LAA clip + ablation, 1 x ablation; note that 1 patient with CABG also received ablation
Values: median (LQ to UQ) or % (n). * P <0.05
XCT: cross-clamp time, CPB: cardiopulmonary bypass, AVR: aortic valve replacement, CABG: coronary artery bypass graft, MVR: mitral valve replacement
