Spanish heart transplant registry. 35th official report of the Heart Failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: Our aim was to describe the characteristics and outcomes of heart transplants in Spain. METHODS: We analyzed trends in recipient and donor characteristics, recipient-donor interaction, surgical procedures, immunosuppression, and outcomes of patients included in the Spanish heart transplant registry from 2014 to 2023. Changes in survival were analyzed using the Kaplan-Meier method. RESULTS: In 2023, 325 cardiac transplants were performed (4.5% more than in the previous year), with a total of 2987 procedures from 2014 to 2023. There was a trend toward performing more transplants in women (29.2%), with etiologies other than cardiomyopathy (32.6%), and with better pretransplant status (less hepatic [12.5%], renal [glomerular filtration rate, 81.5 mL/min/1.73 m2], and respiratory [8.7%] involvement). In 2023, the number of urgent transplants increased (44% of the total), especially those performed after circulatory support with extracorporeal membrane oxygenation (36% of total assistance), and transplants performed with donation after circulatory death (17.9%). Survival improved in the triennium from 2020 to 2022 compared with 2014 to 2016 (83.0% at 1 year from 2020-2022 vs 79.0% from 2014-2016). CONCLUSIONS: The number of transplants performed in Spain showed an upward trend, with recipients with better clinical status and an increasing use of donation after circulatory death. Survival improved in the last triennium. Full English text available from: www.revespcardiol.org/en.

Registro español de trasplante cardiaco. XXXIV informe oficial de la Asociación de Insuficiencia Cardiaca de la Sociedad Española de Cardiología / Spanish heart transplant registry. 34th official report of the Heart Failure Association of the Spanish Society of Cardiology

Introducción y objetivos: El Registro español de trasplante cardiaco actualiza sus datos anualmente. En este artículo se presentan los datos correspondientes al año 2022.Métodos: Se describen las principales características clínicas, del tratamiento recibido y de los resultados en términos de supervivencia de los procedimientos realizados en 2022, así como las tendencias de estos desde el año 2013.Resultados: En 2022 se han realizado 311 trasplantes cardiacos (un 3,0% más que el año anterior). No se han observado cambios relevantes en las características demográficas y clínicas en 2022 respecto a los años inmediatamente anteriores, lo que confirma las tendencias ya descritas en la última década a una disminución de los procedimientos urgentes y el uso de asistencia circulatoria, sobre todo de dispositivos de asistencia ventricular. En el último decenio, las supervivencias son del 81,4 y el 73,4% a 1 año y a los 3 años, con una mejoría numérica que no ha alcanzado significación estadística.Conclusiones: En la última década se observa una estabilización en las características de los procedimientos de trasplante cardiaco y de sus resultados. Registrado en ClinicalTrial.gov (Identificador: NCT03015311).(AU)

Introduction and objectives: The Spanish heart transplant registry updates its data annually. The current update presents the data for the year 2022.Methods: We describe the main clinical characteristics, treatments received, and survival outcomes including procedures performed in 2022, along with their trends since 2013.Results: In 2022, 311 cardiac transplants were performed, representing a 3.0% increase compared with 2021. Compared with previous years, no significant changes in demographic and clinical characteristics were observed in 2022, confirming the trends identified in the last decade. These trends indicate a decrease in urgent procedures and the use of circulatory support, particularly ventricular assist devices. In the last decade, survival rates at 1 and 3 years were 81.4% and 73.4% respectively, with a slight, nonsignificant improvement.Conclusions: In the last decade, there has been a stabilization in the characteristics of heart transplant procedures and their outcomes. This trial was registered at ClinicalTrial.gov (Identifier: NCT03015311).(AU)

Utility of the IMPACT score for predicting heart transplant mortality. Analysis on a contemporary cohort of the Spanish Heart Transplant Registry.

INTRODUCTION AND OBJECTIVES: The Index for Mortality Prediction After Cardiac Transplantation (IMPACT) score was derived and validated as a predictor of mortality after heart transplantation (HT). The primary objective of this work is to externally validate the IMPACT score in a contemporary Spanish cohort. METHODS: Spanish Heart Transplant Registry data were used to identify adult (>16 years) HT patients between January 2000 and December 2015. Retransplantation, multiorgan transplantation and patients in whom at least one of the variables required to calculate the IMPACT score was missing were excluded from the analysis (N = 2810). RESULTS: Median value of the IMPACT score was five points (IQR: 3, 8). Overall, 1-year survival rate was 79.1%. Kaplan-Meier 1-year survival rates by IMPACT score categories (0-2, 3-5, 6-9, 10-14, ≥15) were 84.4%, 81.5%, 79.3%, 77.3%, and 58.5%, respectively (Log-Rank test: p < .001). Performance analysis showed a good calibration (Hosmer-Lemeshow chi-square for 1 year was 7.56; p = .47) and poor discrimination ability (AUC-ROC .59) of the IMPACT score as a predictive model. CONCLUSIONS: In a contemporary Spanish cohort, the IMPACT score failed to accurately predict the risk of death after HT.

Spanish heart transplant registry. 33rd official report of the Heart failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: This report updates the annual data of the Spanish Heart Transplant Registry with the procedures performed in 2021. METHODS: We describe the clinical profile, therapeutic characteristics and outcomes in terms of survival of the procedures performed in 2021. Their temporal trends are updated for the 2012 to 2020 period. RESULTS: In 2021, 302 heart transplants were performed (8.6% increase versus 2020). The tendency in 2021 confirmed that of prior years, with fewer urgent transplants and a preference for the use of ventricular assist devices. The remaining characteristics and survival showed a clear trend toward stability in the last decade. Compared with 2019, the SARS-CoV-2 pandemic (2020 and 2021) did not affect short- or long-term survival. CONCLUSIONS: In 2021, transplant activity returned to prepandemic levels. The SARS-CoV-2 pandemic did not significantly affect transplant outcomes. The main transplant features and outcomes have clearly stabilized in the last decade.

Spanish Heart Transplant Registry. 32nd Official Report of the Heart Failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: The present report updates the main characteristics and outcomes of heart transplants in Spain to 2020. METHODS: We describe the main features of recipients, donors, surgical procedure, and immunosuppression in 2020. We also analyze the temporal trends of these characteristics and outcomes (survival) for the period 2011 to 2019. RESULTS: In 2020, 278 heart transplants were performed (7.3% decrease vs 2019). The findings in 2020 confirmed previous observations of an increase in pretransplant sternotomy, a slight decrease in urgent transplants carried out with ventricular assist devices, a slight decrease in donor age, an increase in the use of allografts with previous arrest, and a decrease in ischemia time. Survival continued to improve in recent triennia, reaching 82.0% at 1 year in the period 2017 to 2019. CONCLUSIONS: The slight decrease in the number of heart transplants performed in 2020 in Spain, most likely due to the SARS-CoV-2 pandemic, did not change the main characteristics of the procedure. No change was observed in the tendency to improved survival.
