Permanent Pacemaker Implantation in a Patient with Congenitally Corrected Transposition of Great Arteries and Mesocardia: An Infrequent Happenstance

Abstract

We present a compelling case of a 37-year-old male who, after three decades of asymptomatic living, was diagnosed with congenitally corrected transposition of great arteries (CCTGA). Initially presenting with troubling symptoms of dizziness and syncope, further evaluation revealed complete heart block, a significant finding necessitating intervention. Despite the rarity of symptomatic presentation in CCTGA, the severity of the heart block prompted the implantation of a DDD pacemaker to ensure adequate management. With meticulous care and precision, the implantation procedure was successfully executed, offering hope for improved cardiac function and symptom relief. Remarkably, the patient remained asymptomatic during subsequent follow-up visits, highlighting the effectiveness of the intervention in mitigating the risks associated with high atrioventricular block in CCTGA. This case serves as a testament to the importance of vigilant monitoring and timely intervention in managing complex cardiac anomalies, ultimately enhancing patient outcomes and quality of life.
