In 16 patients with Starr-Edwards (SE) disc valves, 10 patients with Lillehei-Kaster (LK) valves, and 4 patients with fresh aortic homografts (HG) in the mitral position the hemodynamic qualities of the valves were studied. All three valve types in general showed similar results, but they differed clearly as far as special parameters are concerned. So SE valves had the highest pressure gradients, HG valves the lowest, whereas LK valves were in between. The results of the study lead to the conclusion that tilting disc valves implanted in the mitral position are the best compromise, since they are always available and their hemodynamic response can be tolerated.

Impact of measurement location on direct mitral regurgitation quantification using 4D flow CMR.

Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the ideal location of a measurement plane remains unclear. This study aims to systematically examine how varying measurement locations affect RVol quantification and determine the optimal location using the momentum conservation principle of a free jet.

: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.

Background: The transcatheter edge-to-edge repair (TEER) technique, facilitated by the MitraClip device, is a minimally invasive intervention designed for high-risk patients with mitral regurgitation (MR). This study conducts a retrospective analysis of death events associated with MitraClip implantation over a ten-year decade, utilizing data from the FDA's Manufacturer and User Facility Device Experience (MAUDE) database to evaluate trends in safety outcomes.
Methods: A comprehensive search of the publicly accessible MAUDE database was conducted to retrieve reports of deaths and injuries related to MitraClip implantation from October 2013 to September 2023.
Reintervention after aortic root replacement with allograft, xenograft, and stented bioprosthetic valves.

Division of Cardiac Surgery, Department of Cardiothoracic Surgery, University of Pittsburgh, Pittsburgh, PA, United States of America; Heart and Vascular Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, United States of America. Electronic address:
Background: There has been a significant increase in the utilization of non-mechanical valves in the aortic position over time. However, details in reinterventions after aortic root replacement (ARR) with non-mechanical prosthesis were limited in the literature, despite the potential importance of reinterventions in the lifetime management of aortic valve disease.
Methods: This is a single-center retrospective study, identifying all patients who underwent ARR with allograft, xenografts, and stented bioprosthetic valved conduit from 2010 to 2020.
