SUMMARYPartial anomalous pulmonary venous return (PAPVR) is a congenital anomaly in which one or more, but not all, of the pulmonary veins are connected to a systemic vein or to the right atrium directly. Its incidence is higher in autopsy series than in clinical series.We report 51 cases of PAPVR diagnosed by cardiac catheterization and evaluated from the aspects of age, sex, type and associated anomalies and diseases. (Jpn HeartJ 35: 43-50,1994) Key words: Partial anomalous pulmonary venous return Associated anomalies BNORMALITIES of the pulmonary venous system are not common, although their real frequency is probably greater than that deduced from clinical and autopsy studies.1) The first reported case of anomalous pulmonary venous connection was by Winslow in 1739. In 1942, Brody published a series of 106 cases.2-5) In anatomic terms, the pulmonary venous anomalies may be classified as anomalous connections, stenotic connections and abnormal numbers of pulmonary veins.1) Our subject is "Partial anomalous pulmonary venous return" defined as one or more, but not all, of the pulmonary veins being connected to the right atrium or to one or more of its tributaries. We studied 51 cases of PAPVR admitted to Hacettepe University Pediatric Cardiology Unit between 1972-1991 and diagnosed by cardiac catheterization. All patients were evaluated on the basis of age, sex, type of venous return and associated anomalies and diseases. MATERIAL AND METHODSFifty-one patients with PAPVR diagnosed by cardiac catheterization at the Hacettepe University Pediatric Cardiology Unit between 1972 and 1991 were From the
A case of double-orifice mitral valve (duplication of the mitral valve) in an 18-month-old baby is presented. The valve showed significant regurgitation and was replaced with a No.20 Lillehei-Kaster mitral prosthesis. Patient is kept on dipyridamole (Persantin) 10mg/Kg and aspirin 50mg/Kg daily to avoid postoperative thromboembolic complications. It is emphasized that valve replacement should be the treatment of choice in severe mitral regurgitation associated with double-orifice mitral valve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
