Use of a surgically implanted, nondischargeable, extracorporeal continuous flow circulatory support system as a bridge to heart transplant.

INTRODUCTION AND OBJECTIVES: We aimed to describe the clinical outcomes of the use of the CentriMag acute circulatory support system as a bridge to emergency heart transplantation (HTx). METHODS: We conducted a descriptive analysis of the clinical outcomes of consecutive HTx candidates included in a multicenter retrospective registry who were treated with the CentriMag device, configured either for left ventricular support (LVS) or biventricular support (BVS). All patients were listed for high-priority HTx. The study assessed the period 2010 to 2020 and involved 16 transplant centers around Spain. We excluded patients treated with isolated right ventricular support or venoarterial extracorporeal membrane oxygenation without LVS. The primary endpoint was 1-year post-HTx survival. RESULTS: The study population comprised 213 emergency HTx candidates bridged on CentriMag LVS and 145 on CentriMag BVS. Overall, 303 (84.6%) patients received a transplant and 53 (14.8%) died without having an organ donor during the index hospitalization. Median time on the device was 15 days, with 66 (18.6%) patients being supported for> 30 days. One-year posttransplant survival was 77.6%. Univariable and multivariable analyses showed no statistically significant differences in pre- or post-HTx survival in patients managed with BVS vs LVS. Patients managed with BVS had higher rates of bleeding, need for transfusion, hemolysis and renal failure than patients managed with LVS, while the latter group showed a higher incidence of ischemic stroke. CONCLUSIONS: In a setting of candidate prioritization with short waiting list times, bridging to HTx with the CentriMag system was feasible and resulted in acceptable on-support and posttransplant outcomes.

Temporal trends in the use and outcomes of temporary mechanical circulatory support as a bridge to cardiac transplantation in Spain. Final report of the ASIS-TC study.

BACKGROUND: We aimed to describe recent trends in the use and outcomes of temporary mechanical circulatory support (MCS) as a bridge to heart transplantation (HTx) in Spain. METHODS: Retrospective case-by-case analysis of 1,036 patients listed for emergency HTx while on temporary MCS in 16 Spanish institutions from January 1st, 2010 to December 31st, 2020. Patients were classified in 3 eras according to changes in donor allocation criteria (Era 1: January 2010/May 2014; Era 2: June 2014/May 2017; Era 3: June 2017/December 2020). RESULTS: Over time, the proportion of candidates listed with intra-aortic balloon pumps decreased (Era 1 = 55.9%, Era 2 = 32%, Era 3 = 0.9%; p < 0.001), while the proportion of candidates listed with surgical continuous-flow temporary VADs (Era 1 = 10.6%, Era 2 = 32%, Era 3 = 49.1%; p < 0.001) and percutaneous VADs (Era 1 = 0.3%, Era 2 = 6.3%; Era 3 = 17.2%; p < 0.001) increased. Rates of HTx increased from Era 1 (79.4%) to Era 2 (87.8%), and Era 3 (87%) (p = 0.004), while rates of death before HTx decreased (Era 1 = 17.7%; Era 2 = 11%, Era 3 = 12.4%; p = 0.037) Median time from listing to HTx increased in patients supported with intra-aortic balloon pumps (Era 1 = 8 days, Era 2 = 15 days; p < 0.001) but remained stable in other candidates (Era 1 = 6 days; Era 2 = 5 days; Era 3 = 6 days; p = 0.134). One-year post-transplant survival was 71.4% in Era 1, 79.3% in Era 2, and 76.5% in Era 3 (p = 0.112). Preoperative bridging with ECMO was associated with increased 1-year post-transplant mortality (adjusted HR=1.71; 95% CI 1.15-2.53; p = 0.008). CONCLUSIONS: During the period 2010 to 2020, successive changes in the Spanish organ allocation protocol were followed by a significant increase of the rate of HTx and a significant reduction of waiting list mortality in candidates supported with temporary MCS. One-year post-transplant survival rates remained acceptable.

Heart Failure with Reduced Ejection Fraction and Prognostic Scales: The Impact of Exercise Modality in Cardiopulmonary Exercise Tests.

The cardiopulmonary exercise (CPET) test is an essential tool to determine the severity, prognosis, and need for invasive treatments in heart failure with reduced ejection fraction (HFrEF) but disregards the exercise modality. The present study aimed at analyzing the differences between treadmill and cycle-ergometer exercises. This was a prospective study, involving 65 patients with HfrEF who performed treadmill exercise followed by cycle-ergometer exercise 72 h later. We enrolled 65 patients, aged 58 ± 9 years, with an ejection fraction of 29 ± 9%. Peak VO2 was 20% greater (95% CI: 18−21%; p < 0.000) on the treadmill, and the ventilatory efficiency estimated by the VE/VCO2 slope (32 ± 8 vs. 34 ± 9; p < 0.05). The ventilatory response was greater on the treadmill: maximum ventilation (55 ± 16 vs. 46 ± 11 L/min; p < 0.000) and ventilatory reserve at the maximum effort (28 ± 17 vs. 41 ± 15%; p < 0.000). These values led to a change in the functional class of 23 (51%) patients and ventilatory class of 28 (47%) patients. Differences in the main parameters, including peak VO2 and VE/VCO2, impact prognostic scales and possible advanced treatments; therefore, the results should be interpreted in accordance with the exercise modality.

Infectious complications associated with short-term mechanical circulatory support in urgent heart transplant candidates.

INTRODUCTION AND OBJECTIVES: Short-term mechanical circulatory support is frequently used as a bridge to heart transplant in Spain. The epidemiology and prognostic impact of infectious complications in these patients are unknown. METHODS: Systematic description of the epidemiology of infectious complications and analysis of their prognostic impact in a multicenter, retrospective registry of patients treated with short-term mechanical devices as a bridge to urgent heart transplant from 2010 to 2015 in 16 Spanish hospitals. RESULTS: We studied 249 patients, of which 87 (34.9%) had a total of 102 infections. The most frequent site was the respiratory tract (n=47; 46.1%). Microbiological confirmation was obtained in 78 (76.5%) episodes, with a total of 100 causative agents, showing a predominance of gram-negative bacteria (n=58, 58%). Compared with patients without infection, those with infectious complications showed higher mortality during the support period (25.3% vs 12.3%, P=.009) and a lower probability of receiving a transplant (73.6% vs 85.2%, P=.025). In-hospital posttransplant mortality was similar in the 2 groups (with infection: 28.3%; without infection: 23.4%; P=.471). CONCLUSIONS: Patients supported with temporary devices as a bridge to heart transplant are exposed to a high risk of infectious complications, which are associated with higher mortality during the organ waiting period.

Impact of donor-recipient age on cardiac transplant survival. Subanalysis of the Spanish Heart Transplant Registry.

INTRODUCTION AND OBJECTIVES: The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. METHODS: We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor <50 years for recipient <65 years; b) donor <50 years for recipient ≥ 65 years; c) donor ≥ 50 years for recipient ≥ 65 years, and d) donor ≥ 50 years for recipient <65 years. RESULTS: The most frequent group was young donor for young recipient (73%). There were differences in the median survival between the groups (P <.001): a) younger-younger: 12.1 years, 95%CI, 11.5-12.6; b) younger-older: 9.1 years, 95%CI, 8.0-10.5; c) older-older: 7.5 years, 95%CI, 2.8-11.0; d) older-younger: 10.5 years, 95%CI, 9.6-12.1. On multivariate analysis, independent predictors of mortality were the age of the donor and the recipient (0.008 and 0.001, respectively). The worst combinations were older-older vs younger-younger (HR, 1.57; 95%CI, 1.22-2.01; P <.001) and younger-older vs younger-younger (HR, 1.33; 95%CI, 1.12-1.58; P=.001). CONCLUSIONS: Age (of the donor and recipient) is a relevant prognostic factor in heart transplant. The donor-recipient age combination has prognostic implications that should be identified when accepting an organ for transplant.

INTRODUCCIÓN Y OBJETIVOS: La hiperpotasemia es una preocupación creciente en el tratamiento de los pacientes con insuficiencia cardiaca y fracción de eyección reducida, pues limita el uso de fármacos eficaces. Este trabajo ofrece estimaciones de la magnitud de este problema en la práctica clínica habitual en España, los cambios en las concentraciones de potasio en el seguimiento y los factores asociados. MÉTODOS: Pacientes con insuficiencia cardiaca aguda (n=881) y crónica (n=3.587) seleccionados en 28 hospitales españoles del registro europeo de insuficiencia cardiaca de la European Society of Cardiology y seguidos 1 año para diferentes desenlaces, incluidos cambios en las cifras de potasio y su impacto en el tratamiento. RESULTADOS: La hiperpotasemia (K+> 5,4 mEq/l) está presente en el 4,3% (IC95%, 3,7-5,0%) y el 8,2% (6,5-10,2%) de los pacientes con insuficiencia cardiaca crónica y aguda; causa el 28,9% de todos los casos en que se contraindica el uso de antagonistas del receptor de mineralocorticoides y el 10,8% de los que no alcanzan la dosis objetivo. Del total de 2.693 pacientes ambulatorios con fracción de eyección reducida, 291 (10,8%) no tenían registrada medición de potasio. Durante el seguimiento, 179 de 1.431 (12,5%, IC95%, 10,8-14,3%) aumentaron su concentración de potasio, aumento relacionado directamente con la edad, la diabetes mellitus y los antecedentes de ictus e inversamente con los antecedentes de hiperpotasemia. CONCLUSIONES: Este trabajo destaca el problema de la hiperpotasemia en pacientes con insuficiencia cardiaca de la práctica clínica habitual y la necesidad de continuar y mejorar la vigilancia de este factor en estos pacientes por su interferencia en el tratamiento óptimo

INTRODUCTION AND OBJECTIVES: Hyperkalemia is a growing concern in the treatment of patients with heart failure and reduced ejection fraction because it limits the use of effective drugs. We report estimates of the magnitude of this problem in routine clinical practice in Spain, as well as changes in potassium levels during follow-up and associated factors. METHODS: This study included patients with acute (n=881) or chronic (n=3587) heart failure recruited in 28 Spanish hospitals of the European heart failure registry of the European Society of Cardiology and followed up for 1 year. Various outcomes were analyzed, including changes in serum potassium levels and their impact on treatment. RESULTS: Hyperkalemia (K+> 5.4 mEq/L) was identified in 4.3% (95%CI, 3.7%-5.0%) and 8.2% (6.5%-10.2%) of patients with chronic and acute heart failure, respectively, and was responsible for 28.9% of all cases of contraindication to mineralocorticoid receptor antagonist use and for 10.8% of all cases of failure to reach the target dose. Serum potassium levels were not recorded in 291 (10.8%) of the 2693 chronic heart failure patients with reduced ejection fraction. During follow-up, potassium levels increased in 179 of 1431 patients (12.5%, 95%CI, 10.8%-14.3%). This increase was directly related to age, diabetes, and history of stroke and was inversely related to history of hyperkalemia. CONCLUSIONS: This study highlights the magnitude of the problem of hyperkalemia in patients with heart failure in everyday clinical practice and the need to improve monitoring of this factor in these patients due to its interference with the possibility of receiving optimal treatment

Rationale and design of the optical coherence tomography observation of pulmonary ultra-structural changes in heart failure (OCTOPUS-CHF) study.

BACKGROUND: The assessment of vascular remodeling using optical coherence tomography (OCT) has been previously described in some types of pulmonary hypertension. However, evidence about its feasibility and clinical utility for evaluation of pulmonary arterial vasculopathy in advanced heart failure (HF) is scarce. Optical Coherence Tomography Observation of Pulmonary Ultra-Structural Changes in Heart Failure (OCTOPUS-CHF) study is designed to study the correlation between OCT-morphometric parameters and hemodynamic data measured or derived from right heart catheterization (RHC). METHODS: OCTOPUS-CHF is an observational, prospective, multicentre study aiming to recruit 100 patients with advanced HF referred for heart transplantation (HTx) evaluation. As part of such evaluation, all patients will undergo RHC in order to rule out severe pulmonary hypertension. After RHC, a Dragonfly™ OPTIS™ imaging catheter will be used to perform OCT evaluation of a right-lower-lobe pulmonary artery with a luminal diameter ≤ 5 mm. The primary objective is to study the correlation of OCT parameters with hemodynamic RHC data. The secondary objective is to determine if OCT parameters improve prognostic stratification. CONCLUSIONS: The OCTOPUS-CHF study will investigate the feasibility and clinical utility of pulmonary arterial vasculopathy evaluation with OCT in advanced HF patients and its correlation with hemodynamic RHC data. The ability of OCT-morphometric parameters to improve prognostic stratification will also be tested.

Empleo del balón de contrapulsación intraaórtico como puente al trasplante cardiaco en España: resultados del estudio ASIS-TC / Use of intra-aortic balloon pump as a bridge to heart transplant in Spain: results from the ASIS-TC study

Introducción y objetivos: En España, el balón de contrapulsación intraaórtico (BCIA) se ha usado frecuentemente como puente al trasplante cardiaco (TxC) urgente. El propósito es analizar los resultados de esta estrategia. Métodos: Se realizó una revisión retrospectiva caso por caso de los registros clínicos de 281 pacientes adultos listados para TxC urgente asistidos con BCIA en 16 hospitales españoles entre 2010 y 2015. Se analizaron la supervivencia antes y después del trasplante y la incidencia de eventos adversos. Resultados: Se trasplantó a 194 pacientes (69%; IC95%, 63,3-74,4) y 20 (7,1%; IC95%, 4,4-10,8) fallecieron durante la asistencia, cuya duración media fue de 10,9+/-9,7 días. El BCIA se explantó antes de obtener un órgano a 32 pacientes (11,4%). En 35 pacientes (12,5%; IC95%, 8,8-16,9) se implantó un dispositivo de asistencia circulatoria mecánica completa. El tiempo en la lista de espera urgente se incrementó desde 5,9+/-6,3 días en 2010 hasta 15+/-11,7 días en 2015 (p=0,001). La supervivencia a 30 días y a 1 y 5 años tras el TxC fue del 88,1% (IC95%, 85,7-90,5), 76% (IC95%, 72,9-79,1) y 67,8% (IC95%, 63,7-71,9) respectivamente. La tasa de incidencia de eventos adversos mayores -disfunción del BCIA, ictus, hemorragia o infección- durante la asistencia fue de 26 (IC95%, 20,6-32,4) eventos/1.000 pacientes-día. La tasa de incidencia de explante del BCIA por complicaciones fue de 7,2 (IC95%, 4,5-10,8) casos/1.000 pacientes-día. Conclusiones: En el contexto de listas de espera cortas, el BCIA puede utilizarse como puente al TxC urgente con resultados aceptables. Esta estrategia conlleva una incidencia significativa de eventos adversos

Introduction and objectives: In Spain, intra-aortic balloon pump (IABP) has been used frequently as a bridge to urgent heart transplant (HT). We sought to analyze the clinical outcomes of this strategy. Methods: We conducted a case-by-case, retrospective review of clinical records of 281 adult patients listed for urgent HT under IABP support in 16 Spanish institutions from 2010 to 2015. Pre- and post-transplant survival and adverse clinical events were analyzed. Results: A total of 194 (69%, 95%CI, 63.3-74.4) patients were transplanted and 20 (7.1%, 95%CI, 4.4-10.8) died during a mean period of IABP support of 10.9+/-9.7 days. IABP support was withdrawn before an organ became available in 32 (11.4%) patients. Thirty-five (12.5%, 95%CI, 8.8-16.9) patients transitioned from IABP to full-support mechanical devices. Mean urgent waiting list time increased from 5.9+/-6.3 days in 2010 to 15+/-11.7 days in 2015 (P=.001). Post-transplant survival rates at 30-days, 1-year, and 5-years were 88.1% (95%CI, 85.7-90.5), 76% (95%CI, 72.9-79.1), and 67.8% (95%CI, 63.7-71.9), respectively. The incidence rate of major adverse clinical outcomes-device dysfunction, stroke, bleeding or infection-during IABP support was 26 (95%CI, 20.6-32.4) episodes per 1000 patient-days. The incidence rate of IABP explantation due to complications was 7.2 (95%CI, 4.5-10.8) cases per 1000 patient-days. Conclusions: In a setting of short waiting list times, IABP can be used to bridge candidates to urgent HT with acceptable postoperative results, but there were significant rates of adverse clinical events during support

Venoarterial extracorporeal membrane oxygenation with or without simultaneous intra-aortic balloon pump support as a direct bridge to heart transplantation: results from a nationwide Spanish registry.

OBJECTIVES: To investigate the potential clinical benefit of an intra-aortic balloon pump (IABP) in patients supported with venoarterial extracorporeal membrane oxygenation (VA-ECMO) as a bridge to heart transplantation (HT). METHODS: We studied 169 patients who were listed for urgent HT under VA-ECMO support at 16 Spanish institutions from 2010 to 2015. The clinical outcomes of patients under simultaneous IABP support (n = 73) were compared to a control group of patients without IABP support (n = 96). RESULTS: There were no statistically significant differences between the IABP and control groups with regard to the cumulative rates of transplantation (71.2% vs 81.2%, P = 0.17), death during VA-ECMO support (20.6% vs 14.6%, P = 0.31), transition to a different mechanical circulatory support device (5.5% vs 5.2%, P = 0.94) or weaning from VA-ECMO support due to recovery (2.7% vs 0%, P = 0.10). There was a higher incidence of bleeding events in the IABP group (45.2% vs 25%, P = 0.006; adjusted odds ratio 2.18, 95% confidence interval 1.02-4.67). In-hospital postoperative mortality after HT was 34.6% in the IABP group and 32.5% in the control group (P = 0.80). One-year survival after listing for urgent HT was 53.3% in the IABP group and 52.2% in the control group (log rank P = 0.75). Multivariate adjustment for potential confounders did not change this result (adjusted hazard ratio 0.94, 95% confidence interval 0.56-1.58). CONCLUSIONS: In our study, simultaneous IABP therapy in transplant candidates under VA-ECMO support did not significantly reduce morbidity or mortality.

Use of Intra-aortic Balloon Pump as a Bridge to Heart Transplant in Spain: Results From the ASIS-TC Study.

Pre- and post-transplant survival and adverse clinical events were analyzed. RESULTS: A total of 194 (69%, 95%CI, 63.3-74.4) patients were transplanted and 20 (7.1%, 95%CI, 4.4-10.8) died during a mean period of IABP support of 10.9±9.7 days. IABP support was withdrawn before an organ became available in 32 (11.4%) patients. Thirty-five (12.5%, 95%CI, 8.8-16.9) patients transitioned from IABP to full-support mechanical devices. Mean urgent waiting list time increased from 5.9±6.3 days in 2010 to 15±11.7 days in 2015 (P=.001). Post-transplant survival rates at 30-days, 1-year, and 5-years were 88.1% (95%CI, 85.7-90.5), 76% (95%CI, 72.9-79.1), and 67.8% (95%CI, 63.7-71.9), respectively. The incidence rate of major adverse clinical outcomes-device dysfunction, stroke, bleeding or infection-during IABP support was 26 (95%CI, 20.6-32.4) episodes per 1000 patient-days. The incidence rate of IABP explantation due to complications was 7.2 (95%CI, 4.5-10.8) cases per 1000 patient-days. CONCLUSIONS: In a setting of short waiting list times, IABP can be used to bridge candidates to urgent HT with acceptable postoperative results, but there were significant rates of adverse clinical events during support.

Efficacy and safety of intermittent intravenous outpatient administration of levosimendan in patients with advanced heart failure: the LION-HEART multicentre randomised trial.

AIMS: The LION-HEART study was a multicentre, double-blind, randomised, parallel-group, placebo-controlled trial evaluating the efficacy and safety of intravenous administration of intermittent doses of levosimendan in outpatients with advanced chronic heart failure. METHODS AND RESULTS: Sixty-nine patients from 12 centres were randomly assigned at a 2:1 ratio to levosimendan or placebo groups, receiving treatment by a 6-hour intravenous infusion (0.2 µg/kg/min without bolus) every 2 weeks for 12 weeks. The primary endpoint was the effect on serum concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) throughout the treatment period in comparison with placebo. Secondary endpoints included evaluation of safety, clinical events and health-related quality of life (HRQoL). The area under the curve (AUC, pg.day/mL) of the levels of NT-proBNP over time for patients who received levosimendan was significantly lower than for the placebo group (344 × 103 [95% Confidence Interval (CI) 283 × 103 -404 × 103 ] vs. 535 × 103 [443 × 103 -626 × 103 ], p = 0.003). In comparison with the placebo group, the patients on levosimendan experienced a reduction in the rate of heart failure hospitalisation (hazard ratio 0.25; 95% CI 0.11-0.56; P = 0.001). Patients on levosimendan were less likely to experience a clinically significant decline in HRQoL over time (P = 0.022). Adverse event rates were similar in the two treatment groups. CONCLUSIONS: In this small pilot study, intermittent administration of levosimendan to ambulatory patients with advanced systolic heart failure reduced plasma concentrations of NT-proBNP, worsening of HRQoL and hospitalisation for heart failure. The efficacy and safety of this intervention should be confirmed in larger trials.

Tipología y estándares de calidad de las unidades de insuficiencia cardiaca: consenso científico de la Sociedad Española de Cardiología / Classification and quality standards of heart failure units: Scientific consensus of the spanish society of cardiology

La insuficiencia cardiaca tiene una elevada prevalencia y es el proceso asistencial con mayor carga de enfermedad en España. Las unidades de insuficiencia cardiaca se han desarrollado para sistematizar el diagnóstico, el tratamiento y el seguimiento clínico de los pacientes con dicha enfermedad proporcionando una estructura que coordine las actuaciones de distintas entidades y personas implicadas en el cuidado de los pacientes, con el fin último de mejorar su pronóstico y la calidad de vida. Se dispone de amplia evidencia sobre las bondades de las unidades o los programas de insuficiencia cardiaca, y estas unidades han tenido un importante despliegue en nuestro país. Uno de los retos a los que se enfrenta el análisis de las unidades de insuficiencia cardiaca es normalizar su clasificación determinando qué «programas» se puede identificar como «unidades» de insuficiencia cardiaca, así como su nivel de complejidad, y cuáles no. La finalidad de este documento es exponer los estándares elaborados por la Sociedad Española de Cardiología para clasificar y establecer los requisitos para las unidades de insuficiencia cardiaca dentro del marco del proyecto SEC-Excelente (AU)

Heart failure units have been developed to systematize the diagnosis, treatment, and clinical follow-up of heart failure patients, provide a structure to coordinate the actions of various entities and personnel involved in patient care, and improve prognosis and quality of life. There is ample evidence on the benefits of heart failure units or programs, which have become widespread in Spain. One of the challenges to the analysis of heart failure units is standardization of their classification, by determining which ‘programs’ can be identified as heart failure ‘units’ and by characterizing their complexity level. The aim of this article was to present the standards developed by the Spanish Society of Cardiology to classify and establish the requirements for heart failure units within the SEC-Excellence project (AU)
