Özet
A 35-year-old man with congenitally corrected transposition of the great arteries (ccTGA) and prior ventricular septal defect repair developed pacing-induced cardiomyopathy after 30 years of single-chamber VVI pacemaker use. Right bundle branch area pacing (RBBAP) was chosen for device upgrade due to its potential benefits over conventional cardiac resynchronization therapy. Advanced three-dimensional electroanatomic mapping was employed to navigate a synthetic patch from previous surgery and guide mid-septal electrode placement. Successful RBBAP was achieved with optimal parameters, complemented by atrial and defibrillator lead implantation. At 12 months, the patient showed improved ejection fraction (from 30% to 40%) and stable electrocardiographic results. This case illustrates the role of RBBAP and advanced mapping in addressing complex structural and conduction abnormalities in ccTGA.
