A Novel Technique for Percutaneous Mitral Paravalvular Leak Closure: LBBAP Lead Assisted Ventricular Septal Way

This first reported case of LBBAP-assisted interventricular septal access for mitral PVL closure demonstrates feasibility and safety as an alternative when conventional approaches are not viable. This technique avoids transapical puncture risks and may expand therapeutic options for anatomically challenging structural heart interventions, particularly in patients with double mechanical valves (NCT07129122).
