Prevention of left ventricular outflow tract obstruction in transapical mitral valve replacement: the MitraCut procedure.
EuroIntervention
November 2024
Department of Cardiac Surgery, Medical University Pisa, Pisa, Italy.
Article Synopsis
- The MitraCut procedure is an innovative technique involving endoscopic scissors to cut the anterior mitral leaflet during transapical transcatheter mitral valve replacement (TA-TMVR) to prevent left ventricular outflow tract (LVOT) obstruction.
- In a study across six European centers, outcomes were reviewed for 13 high-risk patients who underwent this procedure, showing a high success rate with minimal complications.
- The findings suggest that the MitraCut procedure is effective at preventing LVOT obstruction, with no postoperative obstructions, a low rate of minor leaks, and no in-hospital or 30-day mortalities among the patients.
Clinical outcomes and predictors of transapical transcatheter mitral valve replacement: the Tendyne Expanded Clinical Study.
EuroIntervention
July 2024
Department of Cardiovascular & Thoracic Surgery, West Virginia University, Morgantown, WV, USA.
Background: Transcatheter mitral valve replacement (TMVR) is a therapeutic option for patients with severe mitral regurgitation (MR) who are ineligible for conventional surgery. There are limited data on the outcomes of large patient cohorts treated with TMVR.
Aims: This study aimed to investigate the outcomes and predictors of mortality for patients treated with transapical TMVR.
Trans-apical catheter ablation of ventricular tachycardia in a patient with metallic aortic and mitral valves.

We present a patient with a history of heart failure and metallic aortic and mitral valves surgeries, who required ablation for a drug-refractory left ventricular tachycardia. But the metallic valves prohibited the insertion of catheters via retrograde or via trans-septal approaches. Therefore, we decided to perform catheter ablation by direct left ventricle puncture through a minithoracotomy.

Residual and recurrent mitral regurgitation after transcatheter edge-to-edge repair are therapeutically challenging. In the present case report, we describe a simplified, transapical electrosurgical laceration and stabilization of clip procedure that represents an alternative and direct approach for electrosurgical laceration of mitral valve leaflets enabling transcatheter mitral valve replacement for recurrent mitral regurgitation after mitral valve transcatheter edge-to-edge repair.

Department of Cardiac Surgery, Medical University of Innsbruck, Anichstrasse 35, A-6020 Innsbruck, Austria.
Background: Failing bioprosthesis is an emerging issue due to (i) a shift towards liberal bioprosthesis implantation instead of mechanical prosthesis and (ii) an ageing population. Management of high-risk patients with bioprosthesis degeneration remains challenging.
Case Summary: An 82-year-old patient with history of aortic and mitral valve replacement six years before presents with severe dyspnoea.
