Take heart: bariatric surgery in obese patients with severe heart failure. Two case reports.

Bariatric surgery may be an effective treatment for obese heart failure patients, enabling access to cardiac transplantation and/or improvement of symptoms. We report the outcomes of two morbidly obese patients with end-stage heart failure, where obesity precluded cardiac transplantation and underwent laparoscopic gastric banding. A 42 year-old male with idiopathic dilated cardiomyopathy weighing 124.4 kg (BMI 42 kg/m(2)) lost 34 kg and was successfully transplanted 11 months later. A 40 year-old woman with familial dilated cardiomyopathy weighing 105 kg (BMI 40 kg/m(2)) lost 14 kg with sufficient symptomatic resolution to no longer require cardiac transplantation. In selected patients with severe heart failure and concomitant morbid obesity, bariatric surgery may be a reasonable treatment option.
