Abstract
We report the first case of unilateral pulmonary edema (UPE) in our series of 150 patients undergoing minimally invasive mitral and tricuspid valve surgery via right thoracotomy. A 30-year-old female with rheumatic heart disease developed UPE requiring temporary extracorporeal membrane oxygenation (ECMO) support postoperatively. The patient recovered uneventfully and was discharged on postoperative day 15. This case underscores the importance of recognizing and mitigating UPE in minimally invasive cardiac surgery (MICS).
