Cardiac surgery for elder patients should be minimally invasive because of their frailty and concomitant multiple chronic diseases. We performed aortic valve replacement (AVR) via upper hemisternotomy (UHS) on an 85-year-old patient who suffered from severe aortic regurgitation with dobutamine support. The postoperative course was uneventful. AVR via UHS is safer than that via right axiallary thoracotomy AVR with shorter aortic cross-clamp time, shorter cardiopulmonary bypass time and fewer complications. AVR via UHS makes ambulation and rehabilitation easier than AVR via full sternotomy, because of thoracic stability. It is more effective and should be more prevalent as minimally invasive cardiac surgery for eldery patients with frailty.

Valvular heart disease (VHD) poses a significant threat to human health, and the transcatheter heart valve replacement (THVR) is the best treatment for severe VHD. Currently, the glutaraldehyde cross-linked commercial bioprosthetic heart valves (BHVs) remain the first choice for THVR. However, the cross-linking by glutaraldehyde exhibits several drawbacks, including calcification, inflammatory reactions, and difficult endothelialization, which limits the longevity and applicability of BHVs.

Background: Vascular and bleeding complications remain a concern after transfemoral transcatheter aortic valve replacement (TAVR). The impact of the sheath type on these complications remains unclear.
Methods: The prospective MARVEL registry study analyzed enrolled 500 patients undergoing large-bore transfemoral procedures and arteriotomy closure with the MANTA vascular closure device from 10 hospitals in Europe and Canada.

Background: The co-existence of severe aortic stenosis (AS) and hypertrophic cardiomyopathy (HCM) is not uncommon. Surgical intervention is the gold standard management. Patients with high surgical risk might undergo transcatheter aortic valve replacement (TAVR).

Aortic annular rupture is a rare and usually fatal complication of TAVR. We report the case of a sub-annular aortic rupture contained in the right ventricle and percutaneously repaired. The procedure was complicated by new-onset severe tricuspid regurgitation related to tricuspid injury during wire externalization and immediately treated by transcatheter edge-to-edge repair.

Objectives: There is limited consensus on the optimal strategy for surgical treatment of severe tricuspid valve pathology. At our institution, we have implemented a unique technique of using a tricuspid homograft with its supporting apparatus for partial replacement of the native tricuspid valve. We now present the long-term outcomes of these patients.
