Congenital mitral atresia.
Mitral atresia is a rare congenital anomaly, but its true incidence is difficult to assess. In 1962, Fontana and Edwards reported 8 cases of isolated mitral atresia and found 24 others in published reports. They also described 5 cases of combined mitral and aortic atresia and found 23 other published cases. From Britain, MacMahon, McKeown, and Record (1953), in a careful survey of congenital he...
متن کاملSingle Ventricle with Mitral and Aortic Atresia
Congenital cardiovascular malformations occur in about 5 to 8 of every 1,000 live births, and the percentage in stillborn infants is probably even higher. Between the 5 and 8 weeks of embryonic life, the primitive heart tube undergoes a process of folding, remodeling with the formation of valves, and septation that transforms its single lumen into the four chambers of the definitive heart. Alth...
متن کاملMitral atresia and occlusive left atrial thrombus.
Mitral atresia and occlusive left atrial thrombus Sir, I have been studying the Case Report on page 649 of the September I969 issue of the British Heart Journal. I would like to suggest a completely different interpretation of the anatomy. I think that the fundamental lesion may be a single atrium with atrioventricular communis, and that the 'left atrium' is actually a common pulmonary vein whi...
متن کاملMitral Atresia Associated with Pulmonary Venous Anomalies.
In mitral atresia with a closed or narrowly patent foramen ovale, anomalous pulmonary venous connexions may occur that function as collateral pathways for the return of pulmonary venous blood to the heart. In 2 cases (Edwards and DuShane, 1950; Lucas et al., 1962), although all the pulmonary veins' connected normally, an anomalous channel-termed a levo-atriocardinal veinformed the collateral pa...
متن کاملMitral Atresia with Normal Aortic Valve
Eighteen cases of mitral atresia with normal aortic valve plus 68 cases from the literature are analyzed. A new classification based on anatomical findings is proposed. Pulmonary stenosis or atresia is frequent in the type with transposition of the great arteries. The rare instances of normal or large left ventricle are due to a large ventricular septal defect, or to straddling or displaced tri...
