Clinical characteristics and surgical outcomes following cardiac myxoma resection

Introduction: Cardiac myxomas are the most common primary cardiac neoplasm (30-50%) with clinical incident of 0.5/ million population. Tranthoracic echocardiography remains the investigation of choice. Surgical excision is curative. The present study aims to analyze demographic and clinical characteristics as well as surgical outcomes in terms of mortality and recurrence of cardiac myxoma. Methods: Thirty patients of cardiac myxoma who met the inclusion criteria during study period study period, January-2018 to April-2024 were included. Data was analyzed for demographic characteristics, echocardiographic findings of myxoma and associated valve lesion, associated valve surgery and survival outcome. Results: Of all subjects, 83.33% presented with dyspnea. Majority of myxoma, 76.67% were attached to interatrial septum. Overall survival at 1- and 3- year was 91.23%. Recurrence free survival at 1-, 3- years and end of this study were 100%, 84.71% and 84.71% respectively. Myxomas with valvular incompetence are rare entity and there is paucity of data and evidences recommending concomitant valve intervention in such cases. There were no immediate peri-operative deaths, however, in contrast to other studies; surgical site infection was the most common post operative complication. Overall survival at 1- and 3- year was 91.23%. Recurrence free survival at 1-, 3- years and end of this study were 100%, 84.71% and 84.71% respectively. Recurrence occurred in first- and third-year following surgery. Conclusion: Study highlights decent outcomes following cardiac myxoma resection. Case specific concomitant valve intervention spiral the success of surgery.
