Key result
Three-dimensional transoesophageal echocardiography successfully identified a 2x3 cm cavernous haemangioma on the anterior mitral valve leaflet, leading to successful surgical resection and valve replacement.
Why the study?
Mitral valve haemangiomas are rare primary cardiac tumours that can cause progressive cardiac failure or sudden death, and their preoperative identification can be challenging.

Three-dimensional transoesophageal echocardiography is a useful adjunctive modality for confirming the diagnosis of rare cardiac tumors, such as a cavernous haemangioma of the mitral valve presenting as severe mitral regurgitation.
Supports adjunctive 3D TOE for rare mitral valve masses; leaves open incremental value in prospective cohorts.
Mitral valve (MV) haemangiomas are rare primary cardiac tumours which may cause progressive cardiac failure as well as sudden death. We present a case of a 44-year-old woman referred for surgical correction of symptomatic severe mitral regurgitation. Preoperative two-dimensional transthoracic and transoesophageal echocardiography (TOE) were reported as demonstrating complex bi-leaflet prolapse causing severe mitral regurgitation. The patient was listed for MV surgery. Only on preoperative CT coronary angiogram was a filling defect noted, leading to suspicion of a cardiac tumour. Prior to skin incision, three-dimensional (3D) TOE revealed a 2×3 cm mass attached to the anterior leaflet of the MV. The tumour was subsequently resected, and the MV replaced. Postoperative histopathology confirmed a large cavernous haemangioma of the anterior MV leaflet. This case highlights a rare cause of severe mitral regurgitation and demonstrates the utility of 3D TOE as an adjunctive modality in confirming the suspected diagnosis of a cardiac tumour.

Bayfield et al. (2022) conducted a case report in Cavernous haemangioma of anterior mitral valve leaflet (n=1). 3D transoesophageal echocardiography and surgical resection was evaluated on Diagnostic confirmation and surgical outcome. Three-dimensional transoesophageal echocardiography successfully identified a 2x3 cm cavernous haemangioma on the anterior mitral valve leaflet, leading to successful surgical resection and valve replacement.
