Abstract

Congenitally Corrected Transposition of Great Arteries (c-TGA) is an anomaly with atrioventricular and ventriculoarterial discordance where left atrium connects to right ventricle and right atrium to left ventricle. However in this case of double inversion, aorta carries saturated blood and pulmonary artery carries venous blood. So, normal physiological circulation is maintained. Our patient, a 38-years-old Bangladeshi male presented with palpitation, dizziness and effort intolerance (NYHAII) during exertion since childhood, which has recently become much worse. However, he had no history of central cyanosis, chest pain or syncope. We diagnosed him as a case of Corrected TGA and second-degree AV block with intermittent complete heart block. A Dual chamber permanent Pacemaker was inserted without any complications. No invasive treatment including corrective surgery was performed because patient’s cardiac function was almost normal. Patient became totally asymptomatic after pacemaker implantation Bangladesh Heart Journal 2022; 37(1): 77-80

先天性纠正性大动脉转位伴房室传导阻滞-心脏结构和电异常共存1例

先天性纠正性大动脉转位(c-TGA)是一种左心房连接右心室和右心房连接左心室的房室和室动脉不一致的异常。然而，在双倒置的情况下，主动脉携带饱和血，肺动脉携带静脉血。因此，正常的生理循环得以维持。我们的病人，38岁的孟加拉男性，自小在运动时出现心悸，头晕和努力不耐受(NYHAII)，最近病情加重。然而，他没有中枢性紫绀、胸痛或晕厥病史。我们诊断他为完全性心脏传导阻滞和二度房室传导阻滞并间歇性完全性心脏传导阻滞。植入双腔永久性起搏器，无任何并发症。由于患者心功能基本正常，没有进行包括矫正手术在内的侵入性治疗。患者在植入心脏起搏器后完全无症状。孟加拉心脏杂志2022;37 (1): 77 - 80
