A 50-year-old male patient with cardiomyopathy (New York Heart Association Class IV, left ventricle ejection fraction of 15%, left bundle branch block, intermittent supraventricular tachycardia, tricuspid regurgitation, and mitral regurgitation) was qualified for a cardiac resynchronization therapy with defibrillator (CRT-D) procedure. CRT-D has become an integral part of systolic heart failure therapy. It can minimize rehospitalization, improve the exercise capacity and well-being of the patient, and potentially decrease mortality. After the CRT-D implantation, electrocardiographic changes were found to be reverted. No hospitalization was reported at 2-year follow-up. The patient survived and regained his quality of life.
