RESUMO

BACKGROUND: Pulmonary arterial hypertension (PAH) represents a marker of bad prognosis in left heart disease. Nonetheless, the effect on survival after heart transplant remains controversial. The objective was to study the impact of preoperative PAH on survival in patients undergoing elective heart transplant. METHODS: A retrospective study of 173 transplant recipients was conducted at a single hospital from January 2009 to December 2018. Congenital etiology and emergent heart transplant were exclusion criteria as well as those patients without enough data in the hemodynamic study. Two groups were considered: A (without PAH) and B (with HTP). PAH was classified as mild (mean pulmonary arterial pressure [mPAP] 25-34 mm Hg, pulmonary vascular resistance [PVR] 2.5-3.4 Wood units and/or transpulmonary gradient [TPG] 13-16 mm Hg), moderate (mPAP 35-44 mm Hg, PVR 3.5-4.9 Wood units and/or TPG 17-19 mm Hg), and severe (mPAP > 44 mm Hg, PVR > 4.9 Wood units and/or TPG > 19 mm Hg). RESULTS: A total of 102 patients were enrolled; 71.6% were male and average age was 52.3 (SD, 10.02) years. The main etiology was ischemic cardiomyopathy; 13.7% underwent previous heart operations. A total of 61 patients (59.8%) had PAH prior to heart transplant: 25 mild, 34 moderate, and 2 severe. Mean overall survival after transplant was 79.9 (SD, 5.68) months, without differences between the 2 groups (P = .82). One-month survival was 89% (the main cause of mortality was primary graft dysfunction), and 1-year survival was 78%. Four patients required mechanical circulatory support during early post-transplant period. CONCLUSIONS: Preoperative PAH does not have a significant impact on survival in elective heart transplant.

RESUMO

BACKGROUND: Prognosis of advanced cardiac light-chain amyloidosis (ACAL) is ominous. Diagnosis of ACAL is frequently preceded by several biopsies of non-clinically affected tissues, which can result in dangerous treatment delays. Combinations of alkylators and steroids have a limited role in its therapy. Definitive efficacy of bortezomib in ACAL is not widely described. In this study we analyze the diagnostic yield of biopsies and compare the effect of bortezomib with other therapeutic strategies in ACAL patients. METHODS: This study is a retrospective analysis of 40 consecutive ACAL patients treated at our hospital (2005 to 2015). For comparison purposes, the cohort was divided into 2 groups: patients treated with bortezomib (n = 23) and those treated with other therapeutic approaches (non-bortezomib, n = 8). RESULTS: Sensitivity of biopsies of non-clinically affected organs was 23%, as compared with 97% for affected organ biopsies (p < 0.0001). The need for >2 biopsies resulted in an average delay in diagnosis of 4.1 months (p = 0.007). Hematologic response was observed in 96% of patients in the bortezomib group compared with 25% in the non-bortezomib group (relative risk = 3.8; 95% confidence interval 1.14 to 12.75; p = 0.0002). Cardiac response criteria were met by 60% of patients in the bortezomib group as compared with none in the non-bortezomib group (p = 0.005). Survival at 6 months and 1 and 2 years for bortezomib patients was 91%, 91% and 73%, as compared with 58%, 15% and 0% for non-bortezomib patients (log rank, p < 0.0001), respectively. CONCLUSION: In our experience, the sensitivity of biopsies from non-affected organs in ACAL is poor and could result in diagnostic delay. Bortezomib was associated with higher hematologic and cardiac response rates as well as survival when compared with other therapies.
