B. Prendergast et al., DOUBLE-ORIFICE RIGHT ATRIOVENTRICULAR VALVE ASSOCIATED WITH PARTIAL ATRIOVENTRICULAR SEPTAL-DEFECT, The Annals of thoracic surgery, 62(3), 1996, pp. 893-895
We describe the case of a double-orifice right atrioventricular valve
that was discovered at operation for an associated atrioventricular se
ptal defect. The diagnosis and operative management are discussed. Dev
elopmental concepts illustrate the mechanism by which this defect aris
es, and emphasize that its great rarity remains an enigma.
