摘 要：Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare heart disease that encompasses an atrioventricular and ventriculoarterial discordance and accounts for less than 1 percent of congenital heart diseases. Objective: To present an atypical case of a man with complex congenital heart disease and conduction anomalies. Case Presentation: This is a case of a 34-year-old patient who came to the hospital with 1 week of dyspnea on exertion and episodes of lipothymia. The patient was referred to our hospital after an electrocardiogram from his primary care with evidence of blocked atrial fibrillation. During the initial evaluation blocked atrial fibrillation was confirmed with a rescue ventricular rate of 38 bpm. A magnetic resonance confirmed the presence of the atrioventricular and ventriculoarterial discordance, the aorta had a left anterior position, perimembranous ventricular septal defect with a right to left shunt, biventricular systolic dysfunction, moderate tricuspid, and mitral regurgitation, interventricular septal intramyocardial and biatrial fibrosis, left atrial dilation, and dilation of the pulmonary artery. After pacemaker placement, the patient has an improvement in his clinical symptoms and quality of life. Conclusions: Cardiac arrhythmias are CCTGA’s leading cause of death, mostly ventricular tachycardia, and atrial fibrillation. Right bundle branch block is a previously unreported and potentially very rare presentati
