“…Most thrombi are sessile without a stalk. However, there have been a few reported cases in which valvular thrombi were pedicled by a stalk 1,18 and were larger than 2 cm. 1 From the present study, we observed that the dimensions of the valvular masses formed a sequence of thrombus > myxoma > papillary fibroelastoma > calcification, which might be indicative of differential diagnoses between each other.…”

Tumors and tumor-like lesions of the heart valves

Valvular tumors and tumor-like lesions may have similar morphological and clinical characteristics, and may place the patients at a high risk of stroke in different ways. From January 2004 to June 2008, 11 patients underwent surgery for a suspected valvular tumor. Valvular tumor and tumor-like lesions accounted for 0.32% of adult cardiac operations. Five (45.5%) valvular lesions were papillary fibroelastomas, one (9.1%) was myxoma, 2 (18.2%) were organized thrombi, and 3 (27.3%) were calcification lesions. There was a total of 5 (45.5%) atrioventricular valve lesions, 4 arising from the atrial side of the leaflets, and one from the ventricular side. All 5 (45.5%) semilunar valvular lesions were from the aortic valve. One (9.1%) lesion originated from the chorda tendinea of the mitral valve. All leaflet lesions were resected by a simple shave technique, and all the patients recovered favorably. Valvular tumor and tumor-like lesions are rare. Pre-operative differential diagnoses among these valvular lesions pose important clinical implications for appropriate treatment for the underlying diseases. Prompt therapeutic measures in view of the underlying diseases of the valvular lesions are essential to prevent potential embolic events.

“…Thrombus associated with the mitral valve is usually sessile but has been rarely reported to arise from a stalk, which may more predisposed to systemic embolism 6. Thrombus is typically of high echodensity although liquefaction can result in areas of echolucency 7.…”

Cavernous haemangioma of anterior mitral valve leaflet: diagnostic utility of 3D echocardiography

et al. 2022

View full text Add to dashboard Cite

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.
