Abstract
Background: Pacemaker lead-induced tricuspid regurgitation is a common complication after cardiac implantable electronic device (CIED) implantation. Cardiac implantable electronic device lead removal is a challenge procedure.
Case summary: A 72-year-old lady was admitted due to worsening heart failure. She had a history of permanent atrial fibrillation and had a permanent single-chamber pacemaker implanted 8 years ago due to complete heart block. Transthoracic echocardiography identified severe lead-related tricuspid regurgitation. The patient underwent successful lead extraction and received a new implantation of left bunch bundle area pacing. Transthoracic echocardiographic examination 2 days after the procedure showed a significant decrease of the tricuspid regurgitation. The patient also reported an improvement in heart failure symptoms.
Discussion: Pacemaker lead-related tricuspid regurgitation introduces negative haemodynamic overload, carrying high risk for the development of heart failure and worse outcome. The present case shows a rapid relief of symptom and improvement of echocardiography findings, indicating the significance of mechanistic approach in the treatment of lead-related tricuspid mechanical interference.
