    Indications, Complications, and Outcomes of Cardiac Surgery After Heart Transplantation: Results From the Cash Study
    (Frontiers Media, 2022-06-09) Gökler, Johannes; Aliabadi-Zuckermann, Arezu Z.; Kaider, Alexandra; Ambardekar, Amrut V.; Antretter, Herwig; Artemiou, Panagiotis; Bertolotti, Alejandro M.; Boeken, Udo; Brossa, Vicens; Copeland, Hannah; Crespo-Leiro, Maria Generosa; Eixerés-Esteve, Andrea; Epailly, Eric; Farag, Mina; Hulman, Michal; Khush, Kiran K.; Masetti, Marco; Patel, Jignesh; Ross, Heather J.; Rudež, Igor; Silvestry, Scott; Martin Suarez, Sofia; Vest, Amanda; Zuckermann, Andreas O.; Surgery, School of Medicine
    Background: Allograft pathologies, such as valvular, coronary artery, or aortic disease, may occur early and late after cardiac transplantation. Cardiac surgery after heart transplantation (CASH) may be an option to improve quality of life and allograft function and prolong survival. Experience with CASH, however, has been limited to single-center reports. Methods: We performed a retrospective, multicenter study of heart transplant recipients with CASH between January 1984 and December 2020. In this study, 60 high-volume cardiac transplant centers were invited to participate. Results: Data were available from 19 centers in North America (n = 7), South America (n = 1), and Europe (n = 11), with a total of 110 patients. A median of 3 (IQR 2-8.5) operations was reported by each center; five centers included ≥ 10 patients. Indications for CASH were valvular disease (n = 62), coronary artery disease (CAD) (n = 16), constrictive pericarditis (n = 17), aortic pathology (n = 13), and myxoma (n = 2). The median age at CASH was 57.7 (47.8-63.1) years, with a median time from transplant to CASH of 4.4 (1-9.6) years. Reoperation within the first year after transplantation was performed in 24.5%. In-hospital mortality was 9.1% (n = 10). 1-year survival was 86.2% and median follow-up was 8.2 (3.8-14.6) years. The most frequent perioperative complications were acute kidney injury and bleeding revision in 18 and 9.1%, respectively. Conclusion: Cardiac surgery after heart transplantation has low in-hospital mortality and postoperative complications in carefully selected patients. The incidence and type of CASH vary between international centers. Risk factors for the worse outcome are higher European System for Cardiac Operative Risk Evaluation (EuroSCORE II) and postoperative renal failure.

    Progressive Left Ventricular Remodeling for Predicting Mortality in Children With Dilated Cardiomyopathy: The Pediatric Cardiomyopathy Registry
    (American Heart Association, 2024) Kantor, Paul F.; Shi, Ling; Colan, Steven D.; Orav, E. John; Wilkinson, James D.; Hamza, Taye H.; Webber, Steven A.; Canter, Charles E.; Towbin, Jeffrey A.; Everitt, Melanie D.; Pahl, Elfriede; Ware, Stephanie M.; Rusconi, Paolo G.; Lamour, Jacqueline M.; Jefferies, John L.; Addonizio, Linda J.; Lipshultz, Steven E.; Pediatric Cardiomyopathy Registry Investigators; Medical and Molecular Genetics, School of Medicine
    Background: Pediatric dilated cardiomyopathy often leads to death or cardiac transplantation. We sought to determine whether changes in left ventricular (LV) end-diastolic dimension (LVEDD), LV end-diastolic posterior wall thickness, and LV fractional shortening (LVFS) over time may help predict adverse outcomes. Methods and results: We studied children up to 18 years old with dilated cardiomyopathy, enrolled between 1990 and 2009 in the Pediatric Cardiomyopathy Registry. Changes in LVFS, LVEDD, LV end-diastolic posterior wall thickness, and the LV end-diastolic posterior wall thickness:LVEDD ratio between baseline and follow-up echocardiograms acquired ≈1 year after diagnosis were determined for children who, at the 1-year follow-up had died, received a heart transplant, or were alive and transplant-free. Within 1 year after diagnosis, 40 (5.0%) of the 794 eligible children had died, 117 (14.7%) had undergone cardiac transplantation, and 585 (73.7%) had survived without transplantation. At diagnosis, survivors had higher median LVFS and lower median LVEDD Z scores. Median LVFS and LVEDD Z scores improved among survivors (Z score changes of +2.6 and -1.1, respectively) but remained stable or worsened in the other 2 groups. The LV end-diastolic posterior wall thickness:LVEDD ratio increased in survivors only, suggesting beneficial reverse LV remodeling. The risk for death or cardiac transplantation up to 7 years later was lower when LVFS was improved at 1 year (hazard ratio [HR], 0.83; P=0.004) but was higher in those with progressive LV dilation (HR, 1.45; P<0.001). Conclusions: Progressive deterioration in LV contractile function and increasing LV dilation are associated with both early and continuing mortality in children with dilated cardiomyopathy. Serial echocardiographic monitoring of these children is therefore indicated.
