In various studies, advanced stage heart disease has been identified most often with the two measurements of left ventricle ejection fraction [generally <35%] and low functional capacity [NYHA III-IV]. Currently, the most appropriate classification system to answer the question of "at what stage of advanced heart failure does the patient require a mechanical support device or heart transplantation treatment?" is the INTERMACS classification (**Figure 1**) [8].
