Introduction:
Many patients with heart failure (HF) suffer from coronary artery disease (CAD) simultaneously, with estimated prevalence ranging from 50% to 65% [1]. Recent data indicate that CAD has become the most common cause of HF, surpassing hypertension and valvular heart disease [2]. Moreover, CAD substantially increases the risk for developing HF, whether it is with reduced or preserved ejection fraction [3]. Despite the somewhat limited evidence regarding the risk of all-cause and cardiovascular mortality, 2021 Expert Consensus Pathway for Optimization of Heart Failure Treatment has recommended coronary revascularization in appropriate patients [4]. Regardless of whether percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) is preferred option, patients with complex coronary occlusions are increasingly not surgical candidates and are referred for hemodynamic-supported complex percutaneous revascularization.
