Assessment of right ventricular anatomy and function in morbidly obese patients has been limited as it is particularly challenging in them.
To assess RV structure and function in morbidly obese patients undergoing bariatric surgery.
Patients accepted for bariatric surgery were prospectively recruited. In each case, CMR was performed on a 1.5 T scanner before surgery and 1 year after the procedure. SSPF cine images were acquired in the 3 orthogonal axes. Manual tracings of the endocardial and epicardial borders at end-diastole and end-systole were performed.
16 patients were included, 13 (81.25%) female. Overall, mean RV mass, RVEDV, RVESV and index values were within normal limits before surgery (the table). After surgery, RV mass decreased, RVED and RVESV decreased by 9%, 12% and 35% respectively, and RV EF improved by 18%.
RV structure and function in morbidly obese patients improve significantly after bariatric surgery. CMR is an accurate tool to assess RV mass, volumes and function in these patients.

Table legend. Data are expressed as mean ±mean standard error. BMI= Body mass index. RVmass: Right ventricular mass. RVED: RV end diastolic volume. RVES: RV end systolic volume. RVSV: RV stroke volume. RVEF: RV ejection fraction. REDVI: Right end diastolic volume index. RESVI: Right end systolic volume index.
