Does percutaneous removal of large tricuspid valve vegetations using suction filtration and veno-venous bypass improve survival and reduce vegetation size in high-surgical-risk patients with tricuspid valve endocarditis?
Percutaneous removal of large tricuspid valve vegetations is a safe and effective alternative for high-surgical-risk patients, achieving high survival rates and significant vegetation debulking.
BACKGROUND: Tricuspid valve surgery has been the de facto standard treatment for tricuspid valve endocarditis (TVE) refractory to medical therapy. It is now possible to remove right-sided vegetations percutaneously using a venous drainage cannula with an extracorporeal bypass circuit. OBJECTIVES: The purpose of our study is to describe our single-center experience of percutaneous tricuspid valve vegetation removal. METHODS: We reviewed the perioperative course of 33 consecutive patients with large tricuspid valve vegetations who carried high surgical risk. RESULTS: The cohort included 12 males and 21 females over a 40-month period with an average age of 37 years. A preponderance of patients carried an admitted or confirmed diagnosis of injection drug use (72.7%). Average vegetation size was 2.1 +/- 0.7 cm prior to the procedure with a 61% reduction in size after the procedure. All patients survived the procedure and 90.9% survived the index hospitalization. Three patients proceeded to elective tricuspid valve replacement due to worsening severity of tricuspid regurgitation. CONCLUSION: Percutaneous removal of large tricuspid valve vegetations is a safe and effective alternative for patients with TVE who carry high-surgical risk. © 2017 Wiley Periodicals, Inc.
