Abstract

PURPOSE: The purpose of this study is to ascertain the clinical manifestations and associated cardiac anomalies of dextrocardia.
METHODS
Twenty-four pediatric patients, who were admitted to, or visited, Dongsan Medical Center Keimyung University and were diagnosed with dextrocardia between January 1996 and July 2001, were enrolled in this study. All patients received echocardiogram and abdominal ultrasonogram to identify structural cardiac anomalies and visceral position.
RESULTS
Among 24 patients, 7 cases were situs solitus(29.2%), 10 cases(41.6%) were situs inversus and 7 cases(29.2%) were situs ambiguous. Most were diagnosed within a week of life(87.5%). They were most commonly cyanotic(45.8%), but eleven cases(45.8%) had no specific symptoms or signs. Nineteen cases(79.2%) had accompanied cardiac anomalies, and pulmonary stenosis or atresia were the most common among them. All the cases of situs solitus and ambiguous had associated cardiac anomalies, but half of the situs inversus had that. Eleven cases were dead by cardiac or extracardiac anomalies during follow up and the mortality rate was higher in situs solitus or ambiguous group than situs inversus group.
CONCLUSION
Dextrocardia accompanies different cardiac and extracardiac anomalies. It's very important to diagnose dextrocardia and associated cardiac or extracardiac anomalies in the early stages of life to improve prognosis.
