Early Feasibility Study with the SATURN Transapical Mitral Valve Replacement Device.
Ann Thorac Surg Short Rep
December 2024
Department of Cardiac Surgery, San Raffaele University Hospital, Milano, Italy.
Purpose: To report the outcomes of the early feasibility study of transapical transcatheter mitral valve replacement (TMVR) with the SATURN System (InnovHeart, Milano, Italy) to treat patients with severe functional mitral regurgitation.
Description: Five high surgical risk patients underwent transapical transcatheter mitral valve replacement with the SATURN System at a single center. One-year follow-up is complete for all patients.
Transcatheter mitral valve implantation in severe mitral annular calcification: a case report.
Eur Heart J Case Rep

HerzZentrum Hirslanden, 8032 Zurich, Switzerland.
Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.
Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.

Background: Rheumatic mitral stenosis (RMS) is a common valvular heart disease in developing countries. We sought to evaluate the early experience of patients with RMS undergoing transcatheter mitral valve replacement (TMVR).
Methods: In this retrospective study, a total of 5 RMS patients accepted TMVR.

Article Synopsis
- Transcatheter closure of paravalvular leaks (PVL) is a viable treatment for high-risk patients, yet limited research exists on its effectiveness using Amplatzer devices in Japanese patients with mitral PVL.
- A study involving 12 patients (average age 78) showed successful closure procedures were performed, with a reduction in PVL severity and no major complications reported within 30 days.
- One year later, an all-cause mortality rate of 16.7% was noted, with 25% of patients needing further intervention due to symptom recurrence, indicating the treatment's potential but also the need for monitoring.
