We describe a successful bioprosthetic annular stretching in a patient with severe prosthetic aortic valve stenosis from a degenerated 19-mm Mitroflow valve (Sorin Group USA Inc, Arvada, CO, USA). This technique allowed for implantation of a 23-mm Evolut-R Pro valve (Medtronic, Minneapolis, MN, USA) with significant improvement in hemodynamics after prosthetic annular stretching. We have also summarized other case series and case reports which have previously described similar techniques.
The objective of this study was to assess imaging predictors of mitral regurgitation (MR) improvement and to evaluate the impact of MR regression on long-term outcome in patients undergoing transcatheter aortic valve replacement (TAVR).BackgroundConcomitant MR is a frequent finding in patients with severe aortic stenosis but usually left untreated at the time of TAVR.MethodsMitral regurgitation was graded by transthoracic echocardiography before and after TAVR in 677 consecutive patients with severe aortic stenosis. 2-year mortality was related to the degree of baseline and discharge MR. Morphological echo analysis was per...
Aortic valve calcification severity has been associated with higher rates of aortic regurgitation (AR) following TAVR, but scarce data exist on its impact with the use of newer generation transcatheter heart valves.
We report our early outcomes of the Ozaki procedure for congenital aortic and truncal valve disease.
This study evaluates the occurrence and predictive factors of conduction anomalies in patients undergoing surgical aortic valve replacement with a rapid-deployment balloon-expandable bioprosthesis in a single-center, real-world experience.
This study aimed to describe experience and show the feasibility and safety of minimally invasive multiple valve implantation with right anterior minithoracotomy (RAT) and compare the outcomes with cases that underwent multiple valve surgery via a standard median sternotomy.
ConclusionsRobotically assisted mitral valve repair was feasible, safe, and therapeutically effective in the first 100 cases, with a minimal learning curve. The robotically assisted approach provides a high-quality surgical view and tremorless suture/cut handling, which will contribute to further development of minimally invasive mitral valve surgery.
AbstractCoarctation is rare in patients over 50 years of age; however, if present, it can be associated with complex intracardiac pathologies and represent a formidable surgical challenge. Herein, we report a single ‐stage approach for surgical repair of coarctation associated with aortic, mitral, and tricuspid valve pathology using an ascending‐to‐descending aortic bypass with posterior pericardial access.
AbstractPurpose of ReviewA combination of evolving 3D printing technologies, new 3D printable materials, and multi-disciplinary collaborations have made 3D printing applications for transcatheter aortic valve replacement (TAVR) a promising tool to promote innovation, increase procedural success, and provide a compelling educational tool. This review synthesizes the knowledge via publications and our group ’s experience in this area that exemplify uses of 3D printing for TAVR.Recent FindingsPatient-specific 3D-printed models have been used for TAVR pre-procedural device sizing, benchtop prediction of procedural compli...
