Article Abstract

A 74-year-old woman with failed mitral surgical repair underwent transcatheter mitral valve-in-ring replacement. Pre-procedural assessment highlighted a substantial risk for valve misalignment and left ventricular outflow obstruction. Electrosurgical laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) technique and transapical wire externalization for valve deployment were successfully employed to prevent these complications.

Objectives: Recurrent mitral regurgitation (MR) after transcatheter edge-to-edge repair (TEER) poses significant clinical challenges, often requiring innovative solutions to address valve dysfunction. A technique combining anterior mitral leaflet laceration using the laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) technique, followed by transcatheter mitral valve replacement may be a novel strategy for managing complex recurrent MR after TEER in patients not deemed to be surgical candidates. The purpose of this report is to describe 2 cases which used this technique.

Background: The LAMPOON (laceration of the anterior mitral leaflet to prevent outflow obstruction) technique has been reported for mitral valve replacement to reduce the risk for left ventricular outflow tract obstruction.

Case Summary: We present the case of a patient who was hospitalized for dyspnea and diagnosed with severe mitral regurgitation. In this case, our team performed modified tip-to-base LAMPOON, which was subsequently followed by successful mitral valve replacement.

Electrosurgery has emerged as a groundbreaking tool in the field of structural cardiac interventions, revolutionizing the approach to complex cardiac conditions. This review delves into the core principles, procedural techniques, outcomes, and potential challenges associated with various electrosurgical procedures within the realm of structural cardiology. Five key electrosurgical procedures performed in complex structural interventions are highlighted in this review.

One of the major issues encountered in patients undergoing evaluation for Transcatheter mitral valve replacement (TMVR) is the risk of Left ventricular outflow tract (LVOT) obstruction. LVOT obstruction is a catastrophic complication of TMVR, the result of displacement of the anterior mitral valve leaflet (AML) toward the interventricular septum. Several strategies to mitigate the risk of LVOT obstruction have been described and include percutaneous laceration of the anterior mitral leaflet (LAMPOON), alcohol septal ablation, trans-atrial leaflet modification (SITRAL) and Balloon Assisted Translocation of Mitral Anterior leaflet to prevent LVOT obstruction (BATMAN).
