A49-year-old
woman underwent cardiac evaluation because of an abnormal ECG. She had
undergone multiple surgical procedures during her infancy for
congenital right tibial aplasia and polydactyly. At the age of 33
years, she had undergone cardiac evaluation after a questionable
episode of supraventricular tachycardia and an
abnormal ECG (Figure 1
). An
echocardiogram revealed left ventricular
hypertrophy; coronary angiography and left
ventriculography were normal.

A routine follow-up in 1998 with a 2D echocardiogram demonstrated
a large apical diverticulum (D) (Figure 2
; LV indicates left ventricle; LA, left
atrium). Cardiac catheterization with left
ventriculography (Figure 3
) and MRI
(Figure 4
) showed a diverticulum
originating at the apex of the left ventricle. The patient underwent
cardiac surgery with excision of the diverticulum and pericardial patch
repair without complications.

Congenital diverticulum of the ventricle is a rare cardiac malformation initially described in 1838.1 It is usually detected in children and was described in detail by Cantrell et al in 1958 as part of a pentalogy.2 The classic clinical picture is characterized by congenital defects involving the abdominal wall, sternum, diaphragm, pericardium, and heart. At least 9 patients, all newborn, with associated limb malformations have been described.3 In 30% of the cases, left ventricular diverticulum is not associated with congenital malformations and is referred to as isolated left ventricular diverticulum.
Prognosis depends on the severity of the cardiac and associated malformations. In patients with complex cardiac malformations who undergo surgery during the first days of life, mortality can be as high as 50%. Cardiac rupture, tamponade, sudden death, endocarditis, peripheral embolism, heart failure, and arrhythmia have all been described as complications and causes of death.3 4
Surgical resection with repair of the associated malformations, even in asymptomatic patients, is the treatment of choice to prevent potentially catastrophic complications.
