[Giant negative T waves in idiopathic apical diverticulum of the left ventricle in adults].

Left ventricular diverticula, congenital or acquired, with normal coronary arteries are rare. Apical diverticula are exceptionally rare in the adult. The authors present the clinical, paraclinical, anatomopathological pre- and postoperative data in a case of apical diverticulum of the left ventricle presenting with giant negative T waves. The differential diagnosis of these electrocardiographic changes is discussed, in particular apical cardiomyopathy, especially as the two conditions may be associated.
