Preoperative pulmonary hypertension and its impact on survival after heart transplantation

Abstract

Objectives: Pulmonary hypertension (PH) due to left heart disease may impair outcome after heart transplantation (HT). To evaluate to what extent previous, and present, haemodynamic criteria discriminate the impact of pre-operative-PH on survival, we characterized the PH in our HT-patients according to ESC's guidelines, ISHLT's summary statement and ISHLT's relative contraindications and criteria for early risk of death after HT.

Design: Records from the 215 HT-patients in Lund during 1988-2010 were reviewed. Subsequent analysis included adults (n = 94) evaluated with right-heart-catheterization at our lab, at rest before HT. End of follow-up was 30th of June 2012.

Results: Survival (mean, n) did not differ (p = ns) for the 94 HT-patients; without (13.0 years, n = 28) or with (13.9 years, n = 66) PH, passive (13.8 years, n = 50) or reactive (12.2 years, n = 13) post-capillary-PH, "modified" passive (13.1 years, n = 40), mixed (16.6 years, n = 23), "modified" reactive (12.6 years, n = 7) or non-reactive (12.2 years, n = 8) post-capillary-PH; or for ISHLT's relative contraindications (12.0 years, n = 22) or increased risk of right-heart-failure and early death (16.5 years, n = 23) after HT.

Conclusions: As previous and present haemodynamic criteria did not sufficiently discriminate the impact of pre-operative-PH for survival after HT at our centre, larger multi-centre studies are encouraged to redefine criteria that may influence outcome.
