Spanish Registry of Acute Aortic Syndrome (RESA). Changes in therapeutic management and lower mortality in acute aortic syndrome.

INTRODUCTION AND OBJECTIVES: The Spanish Registry of Acute Aortic Syndrome (RESA) was launched in 2005 to identify the characteristics of acute aortic syndrome (AAS) in Spain. The aim of this study was to analyze the differences in management and mortality in the 3 RESA iterations. METHODS: We analyzed data from patients with AAS prospectively included by 24 to 30 tertiary centers during the 3 iterations of the registry: RESA I (2005-2006), RESA-II (2012-2013), and RESA III (2018-2019). RESULTS: AAS was diagnosed in 1902 patients (74% men; age, 60.7±12.5 years): 1329 (69.9%) type A and 573 (30.1%) type B. Comparison of the 3 periods revealed that the use of computed tomography increased as the first diagnostic technique (77.1%, 77.9%, and 84.2%, respectively; P=.001). In type A, surgical management increased (79.6%, 78.7%, and 84.5%; P=.045) and overall mortality decreased (41.2%, 34.5%, and 31.2%; P=.002), due to a reduction in surgical mortality (33.4%, 25.1%, and 23.9%; P=.003). In type B, endovascular treatment increased (22.8%, 32.8%, and 38.7%; P=.006), while medical and surgical treatment decreased. Overall type B mortality also decreased (21.6%, 16.1%, and 12.0%; P=.005) in line with a reduction in mortality with medical (16.8%, 13.8%, and 8.8%, P=.030) and endovascular (27.0%, 18.0%, and 9.2%; P=.009) treatments. CONCLUSIONS: The iterations of RESA show a decrease in mortality from type A AAS, coinciding with an increase in surgical treatment and a reduction in surgical mortality. In type B, the use of endovascular treatment was associated with improved survival, allowing better management in patients with complications.

Impact of Preoperative Pulmonary Hypertension on Survival in Patients Undergoing Elective Heart Transplant.

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.
