Acute electrocardiographic correlates post heart transplant in a non-compacted myocardium obese patient: A case report

This work describes a patient with non-compacted myocardium with a very low ejection fraction, type I obesity, with a history of atrial septal defect (ASD) correction, who underwent heart transplantation and the immediate electrocardiographic changes after the procedure. The immediate alterations included atrial fibrillation with a high ventricular response, bradycardia requiring pacing, and alterations due to right ventricular pressure overload (right bundle branch block). After the initial perioperative course, we observed good evolution after transplantation and clinical treatment. At the one-year follow-up, the patient remained without signs of rejection and with grade I functional capacity, free of cardiovascular events.
