Abstract:
Tricuspid stenosis (TS) is an uncommon complication of ventricular pacemaker implantation. Mechanisms described by the literature are ventricular inflow obstruction by tricuspid vegetations (endocarditis) or multiple pacemaker leads and fibrosis secondary to mechanical trauma, accounting for perforation or laceration of the TV leaflets, or adherence between redundant loops and valve tissue. We present the case of iatrogenic tricuspid stenosis, observed in a 77-year-old man. Extrinsic tricuspid valve stenosis was detected by transthoracic echocardiography. Further investigations confirmed the intramyocardial lead position. Tricuspid valve stenosis due to transvenous leads are reported to be treated by surgical replacement, surgical valvuloplasty, or percutaneous balloon valvuloplasty.
