Case series: Criss-cross Heart
Abstract Criss-cross heart (CCH) is a rare cardiac malformation which is characterized by crossing of the inflow streams of the two ventricles due to rotation of ventricular axis. The anomalies can be identified both atrioventricular concordance and discordance. The etiology of CCH is remaining unknown. Prominent symptom is cyanosis. The primary investigation is transthoracic echocardiography to identify this abnormality. Many patients need further investigation to review anatomy. Total correction is the aim for treatment but it is difficult for this complex anatomy. There were 5 patients who visited cardiology clinic at Queen Sirikit National Institute of Child Health (QSNICH) from 2002 to 2017. The objective is to review the treatment options that we performed in CCH. Most common associated anomalies were double outlet right ventricle and pulmonary stenosis. One patient died before surgical intervention; others were performed palliative surgery.
