Persistent iatrogenic muscular ventricular septal lead perforation after pacemaker implantation using delivery sheath...

Ventricular septal perforation is a rare complication of pacemaker implantation. Here, we describe the case of a 69-year-old man with complete atrioventricular block and heart failure. The right ventricular pacemaker was implanted with a long pre-shaped delivery sheath. A new systolic murmur appeared after the procedure. Transthoracic echocardiography revealed a ventricular septal perforation, with a Qp/Qs of 1.09, which was a small shunt rate and required no intervention. The persistent ventricular septal perforation was observed, and the shunt rate remained at 8-month follow-up.

Ventricular septal lead perforation (VSP) is a rare complication of pacemaker implantation. Although iatrogenic VSP generally close spontaneously without adverse clinical outcomes, clinicians should pay attention to the possibility of its persistence.
