Diagnosis and significance of atrial isomerism.

摘要: Fifty-one patients at the Brompton Hospital were identified as having either right or left atrial isomerism by reviewing records and catheterization, echocardiographic and, in 17 cases, autopsy data. Every study patient had 1 more of following conditions: isomeric bronchial anatomy; angiographic necropsy evidence diagnosis isomerism; anomalies systemic pulmonary venous connection. Patients with anomalous connections all additional signs isomerism. Neither nor type was predominant sex. The heart chest slightly often than right. Abdominal visceral heterotaxy most frequent radiographic finding. An ambiguous biventricular connection commonest atrioventricular (AV) A common AV valve mode both forms. Univentricular connection, double-outlet ventricle, atresia discordant ventriculoarterial commoner Left is associated much longer survival, its constellation malformations frequently being less severe amenable to corrective surgery. precise must be made during life order select appropriate treatment.
