We report here on a 43-year-old female patient presenting with non-ST elevation myocardial infarction, severe mitral regurgitation, and mild mitral stenosis secondary to encroachment of the related structures by a primary cardiac angiosarcoma. A coronary angiography revealed significant stenosis in the left main and left circumflex arteries and at exploration, the tumour was arising from posterior left atrial free wall, invading the posterior mitral leaflet, and extending into all of the pulmonary veins and pericardium. Therefore, no further intervention was performed, except for left internal mammarian artery to left anterior descending artery anastomosis and biopsy. As far as we know, this case is unique with respect to its presentation.

Case 1. An 82-year-old man with history of ischemic cardiomyopathy and multiple admissions due to acute decompensated heart failure was evaluated for moderate to severe secondary MR due to atrial dilation (atrial functional MR). TTE showed severe biatrial enlargement with a left atrial volume of 117mL and a left atrial volume index of 65.5ml/m2. It also showed LV of normal size, left ventricular LVIDd of 4.5cm and LVEF of 55%. En face view revealed two central jets arising from the coaptation gaps between posterior mitral leaflet indentations (P1/P2 and P2/P3) (Panel A). (Panel B) Transillumination rendering on 3D TEE, highlighted two distinct coaptation gaps between posterior mitral leaflet scallops. Case 2. A 63-years-old woman with medical history of ischemic cardiomyopathy and heart failure with reduced ejection fraction (35%) was evaluated for moderate to severe secondary MR. TTE showed the LV dilation with LVIDd of 5.7cm. TEE revealed severe eccentric MR. (Panel C) 3D color Doppler TEE imaging of the mitral valve showed a severe regurgitant jet, originated in-between P2 and P3 posterior scallops. (Panel D) Transillumination rendering on 3D TEE, view from left atrium, in systole highlighted the coaptation gap. (Panel E) 3D color Doppler TEE imaging showed residual mild MR after a mitral clip was deployed grasping the medial aspect of P2 and A2 scallops covering the coaptation defect. (Panel F) Transillumination rendering on 3D TEE, view from LV, showed complete resolution of the coaptation gap between posterior scallops after clip deployment.

First Time

Congenital mitral valve incompetence is a rare and complex congenital heart disease in children. We report, a case of a 4-year-old child admitted to hospital with fever, dyspnea on exertion or feeding and repeated respiratory infection for last 3 years. The transthoracic echocardiogram revealed grossly dilated left atrium and left ventricle and severe mitral regurgitation due to cleft in anterior mitral leaflet. Per-operatively mitral valve annulus was found very much dilated; leaflet thinned out and rudimentary posterior mitral leaflet. Morphology of mitral valve was totally distorted, leaflets were diminutive and beyond repairable. Mitral valve replacement was done with 25 mm Edward Life Science porcine tissue heart valve with total preservation of subvalvular structure and the patient showed dramatic symptomatic improvement and later follow up revealed good LV function with alleviation of symptoms. This is a rare and unusual case of congenital mitral valve disease with better prognosis after surgical replacement with tissue valve.
