Right Ventricular Myxoma Involving the Chordae Tendineae: A Case Report and Literature Review

Year: 2024

Type: article

Abstract: This case report describes a rare instance of massive right ventricular myxoma (RVM). A 36-year-old woman initially presented with progressive breathlessness and chest heaviness. Imaging revealed a large mass in the mediastinum, which was initially thought to be a pericardial cyst, and it was unclear whether the mass was intracardiac or extracardiac. Extensive investigations and multiple discussions concluded that the mass was a right ventricular mass. Intraoperatively, the mass was confirmed to be in the right ventricle (RV), with involvement of the chordae tendineae and an extremely thinned-out right ventricular free wall. Surgical excision of the tumour from the RV, tricuspid valve repair, and plication of the free wall were performed, leading to significant symptomatic relief. The mass was identified as a myxoma through histological diagnosis. This case highlights the diagnostic challenges and management strategies for RVM.
