Mean age of the study sample was 50.57 ± 7.33 and 40 patients (81.6%) were male. Approximately half of the patients had ischemic cardiomyopathy (n=25, 51%). 69.4% (n=34) had symptoms compatible with an INTERMACS profile between IV-VII, while the remaining 30.6% (n=15) were classified as INTERMACS II or III. Preoperative visual echocardiographic assessment indicated RVF in 17 (34.7%) of patients. At postoperative day 15, 13 (26.5%) patients had probable and 4 (8.2%) patients had definitive RVF and a total of 10 patients (20.4%) died. Patients with a PDI ≤ 2.41 mmHg/cm2, 2.41 mmHg/cm2 < PDI ≤3.62 mmHg/cm2 and PDI >3.62 mmHg/cm2 were assigned to the PDI tertiles.
