case_images: Echocardiography demonstrated a very low left ventricular ejection fraction (LVEF) of 23%, dilated left ventricle with end-diastolic volume of 424 ml and an elevated left ventricular end-diastolic diameter (LVEDD) of 8.7 cm, severe mitral regurgitation (MR), and mild to moderate eccentric AI (Figure 1). MSCT analysis revealed, the aortic annulus area was 702.1 mm2, area-derived annular diameter was 29.9 mm, annular perimeter was 96.5 mm, and the right and left coronary artery heights were 15.4 and 13.3 mm, respectively (Supplementary Figures S1 and S2).

AV leaflets was sewn using an Ethibond 2/0 suture (Johnson & Johnson Medical N.V., Belgium) to the ventricular myocardium (Valvar Hinge) using three stitches, each leaflet bearing one stitch. A flexible annuloplasty ring [CARBOMEDICS AnnuloFlex TM32 flexible ring (Sorin Group Italia S.r.L., Italy)] was fixed with the native annulus using the same stitches to provide a sturdy base for valve replacement, as illustrated in Supplementary Figure S3 and in Figure 2.
