Pulmonary vein isolation as the fifth column of heart failure therapy: a case report.

ABSTRACT:

Background

Heart failure (HF) and atrial fibrillation often coexist and exacerbate each other, creating a therapeutic challenge when both are present. This case presents a patient with suspected tachycardia-induced cardiomyopathy (TIC) progressing to cardiogenic shock, managed with guideline-directed medical therapy (GDMT) for HF and pulmonary vein isolation (PVI) as an additional therapeutic pillar.

Case summary

We report the case of a 57-year-old male with de novo atrial fibrillation and TIC leading to cardiogenic shock. As rhythm control was initially unsuccessful, mechanical circulatory support was required despite GDMT. A thorough diagnostic work-up was performed, excluding coronary artery disease and structural heart diseases as underlying HF causes, making TIC
