This study reports the longest median survival to date (96 days) of pig hearts transplanted heterotopically into baboons. Duplication of these results in the orthotopic life-supporting position could bring cardiac xenotransplantation to the threshold of clinical application.

With acceptable results in a high-risk population, transapical mitral valve-in-valve implantation can be considered as a complementary approach to reoperative mitral valve surgery in select patients.

MitraClip therapy improves clinical and echocardiographic outcomes at 1 year in about three-quarters of critically ill, elderly patients with moderate to severe MR not amenable to surgery.

The median survival of 76 days in this group of heterotopic porcine-to-baboon cardiac xenografts represents a major advance over the median 27-day survival reported in the literature. Cellular rejection may not constitute a direct major barrier to xenotransplantation. A median survival of 90 days may be achievable with better control of BCMV infection. If further studies in the orthotopic position replicate these outcomes, criteria considered appropriate for clinical application of cardiac xenotransplantation would be approached.

TF-TAVI without pre-dilatation was feasible and safe in this consecutive series of patient regardless of aortic valve morphology, for example. extent of valvular calcification or baseline EOA. This technique resulted in significantly lower fluoroscopy times and amounts of contrast agent while yielding non-inferior hemodynamic and clinical outcome.

Conversion toward a CNI-free immunosuppression (Mycophenolate, sirolimus) is superior to CNI-reduced immunosuppression in improving renal failure in late HTx-recipients. However, this benefit is relativized by the increased incidence and severity of sirolimus/MMF-associated side effects.

MitraClip therapy for the treatment of functional mitral regurgitation (FMR) is an increasingly used intervention for high-risk surgical patients. The aim of this observational study was to assess the impact of residual mitral regurgitation (rMR) at discharge on long-term outcome after MitraClip therapy in patients with FMR.

With growing need for reoperative valve replacement in elderly patients with disproportional operative risks, transcatheter valve-in-valve implantation in aortic and mitral position offers an alternative treatment option. Although valve function after transcatheter implantation was good in all patients, two high risk patients died in the postoperative period due to their significant comorbidities, underscoring the bail-out character of this procedure.
