Long term follow-up of quadruple valve replacement for carcinoid heart disease

Mujtaba Syed Saleem , Shaw James , Clark Stephen

Introduction Carcinoid heart disease most frequently involves the tricuspid or, more rarely, the pulmonary valve and presents with right heart failure as 5-HT is metabolized by the lung. Left-sided valve involvement is quite rare. We describe our experience of 3 patients presenting with heart failure secondary to carcinoid heart disease affecting all four cardiac valves. There are only four previous isolated case reports in the literature. Methods All th...

Carcinoid heart disease: Early outcomes after surgical valve replacement in thirteen patients

Mujtaba Syed Saleem , Chieng Hin Jeremy Ng , Clark Stephen

Aim To describe the early outcomes of carcinoid patients undergoing surgical heart valve replacement.Methods In a retrospective study, records of patients with symptomatic carcinoid heart disease referred for valve surgery between 2012 and 2021 were reviewed. The perioperative and early postoperative outcomes were analyzed.Results Thirteen patients, with a mean age of 64 years (range 55-79 years) underwent cardiac surgery for carci...

Recently, rare loss-of-function mutations of melanocortin-2-receptor accessory protein 2 (MRAP2) have been associated with severe, early-onset obesity in humans. In addition, whole body deletion and targeted brain specific deletion of the Mrap2 gene resulted in severe obesity in mice. In vitro data have shown Mrap2 interaction with the melanocortin-4-receptor (MC4R) affecting receptor signalling as a consequence. However, the mechanism by which Mrap2...
