Enfermedades cardiovasculares - Diferentes enfermedades cardiovascularesEnfermedades cardiovasculares ENDOCARDIAL LEAD CAUSING TRICUSPID STENOSIS Figure 1. Showing TEE mid-esophageal right ventricular inflow–outflow view of heart at enddiastole. The right ventricular lead is seen perforating the septal leaflet of the tricuspid valve. Figure 2. Thirty degree RAO projection showing a waist on balloon inflation in the region of the tricuspid valve. The waist disappeared by the end of the inflation. Also seen is the endocardial ventricular lead passing through the tricuspid valve oriï¬ce. The old capped epicardial leads are also seen. of these cases has included medical management in three (offer of surgery declined in two),2,7,8 surgical lead removal and TV replacement in two,4,5 and surgical lead removal followed by tricuspid valvuloplasty in one.4 We present the only case of successful balloon valvuloplasty for this complication without need for lead removal. It was felt that if lead removal were required this would References 1. Enia F, Lo MR, Meschisi F, Sabella FP.

We conclude that tricuspid stenosis secondary to perforation of a TV leaflet by a transvenous lead may be safely and successfully treated by percutaneous balloon valvuloplasty if lead function is otherwise normal. dial pacing.
