Abstract
INTRODUCTION: During valve replacement, appropriate valve size will be chosen based on many factors, neglecting the potential of the patient for gaining weight. We aimed at evaluating the weight gain potential and its effect on hemodynamics in post mitral valve replacement (MVR) patients. MATERIAL AND METHODS: In 118 post-MVR patients, demographic and echocardiographic data at the time of discharge and follow-up were obtained and analyzed. Primary aim of study is to analyze the hemodynamics of patients based on weight gain/loss. Secondary aim is to evaluate the same in patient-prosthesis mismatch (PPM) subgroup and to evaluate the study population for the potential to gain/loss weight. RESULTS: Among 118 patients, 87 patients (73.7%) gained weight. In 87 weight gained patients, left atrial (LA) size (p = 0.011) and pulmonary artery systolic (PA) pressure (p = 0.028) at follow-up were significantly elevated than the discharge values. Among 53 PPM patients (incidence, 44.9%), 34 patients gained weight and their PA pressure was found to be elevated at follow-up (p = 0.021) whereas weight lost group does not show any significant difference (p = 0.972). Frequency of weight gain was more among patients who weighed < 50 kg preoperatively (28 out of 30) (p = 0.013) and 20 to 30 years age group patients (p = 0.043). No sex predilection was noted (p = 0.149). CONCLUSION: In post-MVR patients, weight gain has definitive influence over hemodynamics. In PPM subgroup, weight gained patients had significantly increased PA systolic pressure at follow-up. Young, < 50 kg weighed, and PPM patients should be advised to maintain their weight post MVR for better hemodynamics. © Indian Association of Cardiovascular-Thoracic Surgeons 2019.
