A case of successful use of biventricular electrocardiostimulation for the treatment of heart failure

Approximately 10% patients with congestive heart failure (HF) have disorders of intraventricular conduction, which (especially a complete blockade of left bundle (CBLB)), induce desynchronization of ventricular contractions and provide further progression of HF signs. In recent years a new method for the treatment of congestive HF in patients with CBLB, the constant biventricular (threechamber) electrocardiostimulation (ECS) has received wide acceptance. Article presents a case of the first in St. Petersburg successful use of biventricular ECS for the treatment of HF. Female patient R. (aged 73 years) underwent constant biventricular ECS for pronounced HF (IV NYHA functional class) in the presence of CBLB with the width of QRS complexes of 160 msec, considerable left ventricular (LV) dilatation, and decreased LV systolic function. A control examination was performed 6 months after the surgery. The HF functional class decreased to the second; the LV ejection fraction (EF) increased from 25 to 33%; and paroxysms of ventricular tachycardia, atrial fibrillation and flutter disappeared. Therefore constant biventricular ECS is a novel, efficient and low-traumatic method for the treatment of congestive HF resulting from desynchronized ventricular contractions in the presence of CBLB.
