[Coronary Artery Bypass Grafting and Biventricular Pacing for Severe Heart Failure due to Dilated Cardiomyopathy]

Area of Science:

• Cardiology
• Cardiac Surgery
• Electrophysiology

Context:

• A 57-year-old male patient presented with dilated cardiomyopathy and coronary stenosis.
• Initial medical therapy provided temporary relief, but symptoms recurred, leading to readmission for severe heart failure.
• The patient exhibited a complete left bundle branch block and prolonged QRS interval, indicative of conduction system disease.

Purpose:

• To evaluate the efficacy of biventricular pacing with surgical epicardial leads in a patient with severe left ventricular systolic dysfunction and heart failure.
• To assess the impact of combined coronary artery bypass grafting and cardiac resynchronization therapy on cardiac function.

Summary:

• Coronary artery bypass grafting and biventricular pacing with surgical epicardial leads were performed due to aggravated left ventricular systolic dysfunction and coronary artery stenosis.
• The combined surgical intervention resulted in significant improvement in left ventricular systolic function.
• Post-operative recovery demonstrated the effectiveness of the chosen therapeutic strategy.

Impact:

• Biventricular pacing using surgical epicardial leads presents a viable therapeutic option for patients undergoing open heart surgery for severe left ventricular systolic dysfunction.
• This case highlights the successful application of cardiac resynchronization therapy in managing complex cardiac conditions.
• The findings support further investigation into this combined approach for heart failure management.
