Edge‐to‐edge tricuspid valve repair for severe tricuspid regurgitation 20 years after cardiac transplantation

Abstract

Abstract Tricuspid valve regurgitation in orthotopic heart transplant recipients is common. Surgical corrections have been the mainstay of the treatment for diuretic‐refractory heart failure due to severe tricuspid regurgitation. However, post‐transplant patients inherently carry higher surgical risk owing to previous sternotomy and immunocompromised state. We report a case of successful percutaneous edge‐to‐edge tricuspid valve repair for severe tricuspid regurgitation after cardiac transplantation. A 27‐year‐old man with a history of idiopathic restrictive cardiomyopathy status after orthotopic heart transplant presented with severe right‐sided heart failure symptoms. A transthoracic echocardiogram showed bi‐atrial enlargement and moderate‐to‐severe tricuspid regurgitation, and an increase to the severe range with exercise. Percutaneous edge‐to‐edge tricuspid valve repair was performed. The patient's symptoms improved, and follow‐up echocardiogram showed mild tricuspid regurgitation. Percutaneous tricuspid valve repair can be considered as an alternative option to conventional surgery for symptomatic severe tricuspid regurgitation in orthotopic heart transplant recipients with suitable anatomy.
