Isolated atrioventricular discordance

A case of isolated atrioventricular discordance.

A case of isolated atrioventricular discordance in situs solitus is described. The importance of a well defined situs and of the presence of both ventricles in making this diagnosis is underlined and previous published reports reviewed. It is suggested that the haemodynamic concept of isolated atrioventricular discordance cannot be described only by the spatial relation between the ventricles (...

Straddling right atrioventricular valves in atrioventricular discordance.

Four hearts are described in which the right atrioventricular valve, draining a morphologically right atrium, straddled and overrode a septum between a right-sided chamber of left ventricular morphology and a left-sided chamber of right ventricular morphology. The degree of override varied between the straddling valve and was committed by 20-45% to the morphologically right ventricle. The ventr...

Complete atrioventricular block in patients with atrioventricular discordance.

Although patients with atrioventricular (AV) discordance (corrected transposition) have abnormal conduction pathways and may spontaneously develop high-grade AV block, no quantitative assessment of the risk of this happening is available. We reviewed the data on 107 patients with AV discordance ages 2-76 years (mean 22 years) at follow-up. Eighty-two patients (77%) had a ventricular septal defe...

A case of double-outlet left ventricle with atrioventricular discordance.

The clinical, echocardiographic and angiographic aspects of a four-month-old boy with double-outlet left ventricle, atrioventricular discordance, L-malposition of the great arteries, ventricular septal defect and pulmonary stenosis are described. Additionally, in this patient, the right arcus aorta and the ligament of ductus arteriosus caused anterior compression of the trachea. The anterior po...
