“…[1][2][3][4][5] In addition, recently, an association with isolated left ventricular noncompaction has also been reported. 7 This case presentation is the first reporting the association of double-orifice mitral valve with nonisolated ventricular noncompaction. Some reports have classified double-orifice mitral valve into 3 types.…”

Double-orifice mitral valve is a rare congenital anomaly. Although it is more frequently associated with other cardiac abnormalities, it may occur as an isolated lesion. There are 2 forms of myocardial noncompaction: isolated and nonisolated myocardial noncompaction. Nonisolated myocardial noncompactions are occasionally reported postnatally in association with congenital heart anomalies such as ventricular septal defect, pulmonic stenosis, and atrial septal defect. To our knowledge, this is the first case presentation reporting a double-orifice mitral valve associated with nonisolated myocardial noncompaction.

“…The latest case report concerning DOMV has been its association with isolated left ventricular noncompaction (ILVNC). 7 However, to our knowledge, the following is the first re-ported case of DOMV associated with nonisolated left ventricular noncompaction (NILVNC).…”

“…Left ventricular NVM associated with DOMV is a very rare pathology although this association has been reported previously [ 10 - 13 ]. Therefore, we present a case of left ventricular NVM associated with DOMV in an adult woman, which was confirmed by transthoracic two-dimensional and three-dimensional echocardiography, and discuss the possible mechanism of the association.…”

A 24-year-old woman admitted with mild chest distress associated with activity without chest complaint for twenty days. Two orifices were visible at the level of the mitral valve with a transthoracic short-axis view of the two-dimensional and three-dimensional echocardiography. The left ventricle was mildly dilatated and the left ventricular wall was thickened, especially at the apex and anterolateral wall, and appeared sponge-like. There were numerous, excessively prominent trabeculations associated with intertrabecular recesses. Although the coexistence of NVM and DOMV could be a coincidence, we believe that both defects were probably caused by a developmental arrest of the left ventricular myocardium in the present case.

Double-Orifice Mitral Valve Associated with Noncompaction of Left Ventricular Myocardium

Double-orifice mitral valve (DOMV) is a rare anomaly commonly associated with other congenital heart diseases. We present two patients with DOMV and noncompaction of the left ventricular myocardium (NLVM). Case 1 was a 5-year-old male diagnosed with dilated cardiomyopathy. His echocardiogram showed thin myocardium with dilatation at the basal of the left ventricle, thick noncompacted myocardium around the apex of the left ventricle, and DOMV (complete bridge type) with mild mitral regurgitation. Case 2 was an 11-year-old male diagnosed with complete atrioventricular block. His echocardiogram showed thick noncompacted myocardium with mild hypokinesis from the posterior to lateral wall and DOMV (complete bridge type) with mild mitral regurgitation. DOMV is commonly associated with congenital anomaly and always has an abnormal subvalvar apparatus. The mitral valve and its apparatus embryologically originate from the endomyocardium, which is thought to be the origin of noncompacted myocardium. We speculate that patients with DOMV may have NLVM.
