Background: Bariatric surgery is an effective option for weight control in morbid obesity. The goal of this study was to assess cardiac risk prior to bariatric surgery using transesophageal-dobutamine stress echocardiography (TE-DSE). Methods: 7 morbidly obese patients (mean BMI 67.7 ± 15.6) were prospectively evaluated by TE-DSE prior to bariatric surgery. Results: All patients underwent TE-DSE without complications. 6 of 7 patients had no evidence of ischemia on TE-DSE. One patient had abnormal TE-DSE showing inferior ischemia and was treated with beta-blockers and nitrates prior to surgery and had no complications. All patients underwent surgery without cardiac complications. 1 patient died at 18 days of sepsis. Over a mean follow-up period 11 months, the 6 surviving patients have not experienced any cardiac events. Their average weight loss is 58.2 kg. Conclusion: TE-DSE is a valuable noninvasive technique for predicting cardiac risk in morbidly obese patients undergoing bariatric surgery.
