We present a rare case of a 48 year old man, coming with Rheumatic heart disease, mitral regurgitation, aortic regurgitation and LV non compaction. This is a very rare combination of diseases.

A 48-year-old male presented to us with dyspnea on exertion and palpitations for the past 8 months. On cardiovascular examination, a loud pansystolic murmur of mitral regurgitation was heard at apex and a long blowing diastolic murmur suggestive of aortic regurgitation was heard in the neo-aortic area. EKG was suggestive left ventricular volume overload and chest X-ray demonstrated cardiomegaly with a cardiothoracic ratio 0.65.
Transthoracic echocardiography revealed valvular changes suggestive of rheumatic heart disease. Anterior mitral leaflet was thickened with diastolic doming while posterior mitral leaflet had restricted mobility with mal-coaptation giving rise to moderate mitral regurgitation [Figure 1]a and Video 1]. Aortic valve was tricuspid with thickened and retracted leaflet tips giving rise to severe aortic regurgitation [Figure 1]b. Left ventricle (LV) was globally hypokinetic (ejection fraction = 25%–30%) with prominent and broad trabeculae with deep intertrabecular recess in the apical and inferolateral areas of LV [[Figure 1]c and [Figure 1]d and Videos 2 and 3]. Color Doppler evaluation revealed perfusion of intertrabecular recess [Figure 1]e and Video 4]. The final diagnosis of rheumatic severe aortic regurgitation and moderate mitral regurgitation with LV noncompaction was made. The patient was advised aortic valve replacement along with mitral valve repair but refused by the patient and is currently stabilized on torsemide, spironolactone, carvedilol, and ramipril.

Left ventricular noncompaction cardiomyopathy (LVNC) is a rare myocardial disorder characterized by prominent left ventricular trabeculae, deep intertrabecular recesses, and the thin compacted layer. It results from the arrest of the normal compaction process of the developing myocardium, resulting in deep intertrabecular recesses which communicate with the ventricular cavity unlike sinusoids.
LVNC may be isolated or associated with a number of congenital and valvular heart diseases. Heart failure, cardioembolic events, and ventricular arrhythmias are the common modes of presentation.
Echocardiographic diagnostic criteria have been laid for LVNC and include noncompacted endocardial layer with trabeculations and deep recesses, noncompaction to compaction ratio of ≥2:1 at end systole, color Doppler evidence of flow in intertrabecular recesses, and predominant localization in the apical, mid-lateral, and mid-inferior regions. However, the diagnosis is increasingly verified or made by the use of cardiac magnetic resonance imaging. Available data indicate that LVNC generally has a poor prognosis.
Our case is a very rare case depicting the association of rheumatic aortic and mitral regurgitation with left ventricular noncompaction. This association is of clinical significance because this might exacerbate the left ventricular dysfunction caused by chronic aortic and mitral regurgitation. Postoperative outcomes might also be worse as recovery of cardiac mechanical function is less likely in the presence of a preexisting myocardial disease (LVNC).
