A rare complication of transcatheter aortic valve replacement: Right ventricular intramyocardial hematoma

Abstract

Right ventricular (RV) intramyocardial hematoma is a rare yet potentially life-threatening complication associated with percutaneous coronary intervention (PCI), cardiac surgery, and catheter ablation. Here, we present a unique case of RV intramyocardial hematoma that developed within hours following transcatheter aortic valve replacement (TAVR). The patient experienced hemodynamic instability due to compression of the right ventricular outflow tract (RVOT). The clinical presentation and echocardiographic findings initially suggested tamponade, prompting urgent surgical exploration with redo-sternotomy. Intraoperative findings enabled the refinement of the diagnosis and led to a conservative management approach, resulting in a favorable outcome.
