[Full Reverse Left Ventricle Conteractility Function Remodeling and Recovery in Patient With Dilated Cardiomyopathy. Clinical Case].

Abstract

The article presents a clinical case of a patient with severe chronic heart failure of ischemic origin. In 2020, the patient with a long history of ischemic heart disease, as confirmed by clinical data and instrumental examination, was diagnosed with severe cardiomegaly and NYHA class III chronic heart failure. The course of heart failure was aggravated by the presence of arrhythmia in the form of atrial fibrillation. At the first stage, a drug therapy and lifestyle modifications were recommended. In 2021, a beneficial tendency in clinical and instrumental indexes was observed, which made it possible to move on to the surgical stage of treatment. A coronary artery bypass grafting was performed with ablation of the left atrial posterior wall using the "box lesion" technique. A follow-up examination performed a year later showed normalization of the left ventricular dimension and recovery of its contractile function. The symptoms of heart failure regressed to the level of NYHA functional class I; no relapses of atrial fibrillation were detected. The patient continues to receive recommended drug therapy.
