Convergence of the fields of heart failure (HF) and interventional cardiology has led to the formation of a discipline referred to as interventional HF. Although the term may be applied to essentially any invasive procedure performed in patients with HF (eg, coronary angiography, percutaneous coronary intervention, invasive assessment of hemodynamics), it is more commonly reserved for the application of invasive diagnostic or therapeutic procedures to improve the clinical decision-making, functional status, and outcomes of HF patients. This article reviews developing modalities.
