Abstract :
Background: Congenital ventricular diverticula, defined as a protrusion of the free wall of the ventricle
including the endocardium, the myocardium, and the pericardium, behave similarly to an
accessory ventricular chamber which contracts synchronously with the normal ventricles.
Case Presentation: A 42-year-old man presented with functional class II exertional dyspnea, fatigue,
and flushing. Transthoracic echocardiography showed deep recesses with the outpouching of
the basal-to-mid free wall and septal hyperkinesia. All the echocardiographic data were highly
suggestive of isolated right ventricular (RV) noncompaction. Magnetic resonance imaging
revealed multiple large outpouchings in the RV free wall, the RV outflow tract, and the basal
anterior left ventricular wall, which had a wide neck and a normal contractility. The left
ventricular myocardium was hypertrabeculated but did not fulfill the noncompaction criteria of
cardiac magnetic resonance imaging.
Conclusions: A muscular type of diverticula with prominent trabeculation and normal contractility, but
without abnormalities, on both perfusion and gadolinium enhancement images was reported
here. Such cases should not be mistaken for noncompaction or pseudoaneurysms.
