Data expressed as median (interquartile interval); MR: mitral regurgitation; Group 1 - patients whose moderate/severe MR remained after transcatheter aortic valve implantation (TAVI); Group 2 - patients whose moderate/severe MR improved to trace/mild after TAVI; Group 3 - patients whose trace/mild MR remained after TAVI; Group 4 - patients whose trace/mild MR worsened to moderate/severe after TAVI; LVEF: left ventricular ejection fraction; LVEDD: left ventricular end-diastolic diameter; LVESD: left ventricular end-systolic diameter; LA: left atrium.
