Article Abstract
Background: Continuous retrograde flow across the aortic valve from left ventricular assist device (LVAD) therapy can result in cusp damage and progressive aortic regurgitation, potentially triggering recurrent heart and multiorgan failure. The management of aortic regurgitation after LVAD implantation has not been well defined.
Methods: This study retrospectively reviewed the investigators' experience with the management of de novo aortic regurgitation requiring intervention in patients with continuous-flow LVAD.
Results: Six patients who had undergone LVAD implantation and who required intervention were identified. Two patients underwent redo sternotomy with bioprosthetic aortic valve replacement, and 4 patients underwent percutaneous management, including Amplatzer device (Abbott) placement and transcatheter aortic valve replacement. All patients had resolution of aortic regurgitation with improved hemodynamics and relief from heart failure. One early and 2 late deaths occurred. Valve function was intact, with all valves opening intermittently without greater than trivial aortic regurgitation.
Conclusions: Multiple treatment modalities exist for LVAD-induced aortic valve regurgitation, including open surgical and percutaneous strategies. With a tailored risk-adjusted approach, acceptable results may be achieved.

Background: Chronic kidney disease (CKD) is associated with a higher prevalence of valvular diseases and increased mortality from cardiovascular causes. Factors that influence the genesis of cardiac valve calcification (CVC) in these patients are not well-defined.
Objective: To determine the risk factors for valvular calcification in patients with CKD.

Plug-based vascular closure device in transfemoral transcatheter aortic valve implantation.

Objectives: Failure of vascular closure device (VCD) is the most common cause of access-site vascular complications in transfemoral transcatheter aortic valve implantation (TAVI). The authors sought to determine if the systematic use of arteriotomy-site ballooning with concomitant manual compression following the delivery of a plug-based VCD (MANTA, Teleflex) can optimize toggle-plug assembly apposition to the common femoral artery (CFA) wall and improve the final hemostatic efficacy.
Methods: In this prospective, observational, single-center study, 323 consecutive patients undergoing transfemoral TAVI from October 2021 to December 2024 underwent access closure with the MANTA VCD.
Right coronary artery takeoff plane and implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention embolic protection devices.

Objectives: The authors hypothesized that the origin of the right coronary artery (RCA) is a direct continuation of the major aortic arch branches (MAAB) takeoff plane, which may have implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention (TAVI) embolic protection devices (EPDs).
Methods: In this single-center, retrospective, cross-sectional study, the authors analyzed computed tomographic angiography (CTA) images from 92 patients undergoing TAVI evaluation to determine the spatial relationship between the origin of the RCA and the MAAB takeoff plane. Patients with prior cardiothoracic or aortic interventions and those with anomalous RCA origin were excluded.

Objective: This meta-analysis aimed to compare the perioperative safety and efficacy of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in bicuspid aortic valve (BAV) stenosis.
Methods: We systematically analyzed studies from PubMed, Cochrane Library, Embase, and CNKI comparing TAVR and SAVR in BAV stenosis. Outcomes included postoperative mortality, complications, all-cause survival, and freedom from stroke.
