Common misdiagnosis reason and differential diagnosis of patients with double outlet right ventri-cle diagnosed by ultrasonic cardiogram

Abstract

Objective To investigate the common misdiagnosis reason and differential diagnosis of patients with double outlet right ventricle（ DORV ） diagnosed by ultrasonic cardiogram. Methods Twenty-seven patients with DORV admitted at the first people ’s hospital of Shangqiu from May 2008 to August 2011 were retrospectively analyzed. Eighteen cases of them were tetralogy of Fallot,5 cases of them were Eisenmenger type,3 cases of them were right artery ectopic（ D-malposition, Taussig-Bing symptom）and 1 case of them was left artery ectopic（ L-malposition）. Results Eleven cases with tetralogy of Fallot were confirmed and 7 cases with tetralogy of Fallot were corrected to DORV of tetralogy of Fallot. Two patients with Eisenmenger were confirmed and 3 patients with ventricular septal defect combined pulmonary hypertension were corrected to DORV. All patients with Taussig-Bing symptom and left artery ectopic were confirmed. All patients were performed with surgical operation. Conclusions There are different characteristics on supersonic and enchanted because of different types for patients with DORV and it overlapped with tetralogy of Fallot,ventricular septal defect combined pulmonary hypertension and transposition of the great arteries. Therefore we should strictly distinguish them and try to avoid the misdiagnosis. Key words: Double outlet right ventricle; Ultrasonic cardiogram; Misdiagnosis; Analysis
