Abstract

Introduction: Benign intracardiac tumours are the most common of the 5% of primary tumours and account for 90% of intracardiac tumours. Myxoma, which is the main benign tumour, rarely localizes to the mitral valve, in the order of 1-5%, associated with severe symptoms and enormous complications.

The objective is to report a rare and severe case of mitral valve myxoma resulting in severe obstruction of the valve orifice.

Presentation of Case: A 65-year-old Moroccan woman, without profession, the diabetic patient presented with progressive dyspnoea, in whom transthoracic echocardiography (TTE) completed by transesophageal echocardiography (TEE), a cardiac magnetic resonance imaging (MRI), a cerebro-throracoabdominopelvic Positron emission tomography-scan (PET-scan) showed a cauliflower-shaped mass embedded in the small mitral valve, evoking the diagnosis of myxoma, confirmed by the anatomopathological examination. A lumpectomy with mitral valve plasty was performed in association with coronary artery bypass surgery for a tri truncal lesion. The evolution was marked by an improvement in the clinical and echographic state.

Discussion: Myxoma is the first benign tumour encountered in women between the 3rd and 6th decade, whose diagnosis is evoked by a TTE, better by a TEE or more, by a computed tomography (CT scan) or even a cardiac MRI which specifies the visualization of the soft parts with all the internal details of the myxoma, whose confirmation is carried out on the histopathological analysis of the operating room.

Conclusion: The management was based on complete resection of the tumor associated with mitral valve plasty.

Keywords: Stenosing intracardiac mass, mitral valve, intracardiac myxoma
