U. Janssens et al., CONGENITAL QUADRICUSPID AORTIC-VALVE ANOMALY ASSOCIATED WITH HYPERTROPHIC NONOBSTRUCTIVE CARDIOMYOPATHY - A CASE-REPORT AND REVIEW OF THE LITERATURE, HEART, 78(1), 1997, pp. 83-87
A case is reported of a 38 year old woman without known cardiac congen
ital abnormality but a history of well. controlled arterial hypertensi
on who was admitted to hospital after successful resuscitation at home
following cardiac arrest. There was no evidence of myocardial infarct
ion on 12-lead electrocardiogram but there were signs of left ventricu
lar hypertrophy. Transoesophageal echocardiography revealed a rare qua
dricuspid aortic valve (QAV) malformation with concomitant mild aortic
regurgitation. The left ventricle showed a massive concentric hypertr
ophy without obstruction. The patient was eventually transferred in a
persistent vegetative state to a home care facility. A review of the l
iterature revealed 70 cases of QAV diagnosed by transthoracic or trans
oesophageal echocardiography (26 cases), at necropsy (25), during surg
ery (15), and during angiography (4). The present case is the first re
port of QAV associated with non-obstructive hypertrophic cardiomyopath
