RESUMO
BACKGROUND: The current incidence and outcomes of structural transcatheter procedures in heart transplant (HTx) recipients and left-ventricular assist devices (LVAD) carriers is unknown. AIMS: To provide insights on structural transcatheter procedures performed across HTx and LVAD patients in Spain. METHODS: Multicenter, ambispective, observational nationwide registry. RESULTS: Until May/2023, 36 percutaneous structural interventions were performed (78% for HTx and 22% for LVAD) widely varying among centers (0%-1.4% and 0%-25%, respectively). Percutaneous mitral transcatheter edge-to-edge (TEER) was the most common (n = 12, 33.3%), followed by trancatheter aortic valve replacement (n = 11, 30.5%), and tricuspid procedures (n = 9, 25%). Mitral TEER resulted in mild residual mitral regurgitation in all but one case, mean gradient was <5 mmHg in 75% of them at 1-year, with no mortality and 8.3% re-admission rate. Tricuspid TEER resulted in 100% none/mild residual regurgitation with a 1-year mortality and readmission rates of 22% and 28.5%, respectively. Finally, trancatheter aortic valve replacement procedures (n = 8 in LVADs due to aortic regurgitation and n = 3 in HTx), were successful in all cases with one prosthesis degeneration leading to severe aortic regurgitation at 1-year, 18.2% mortality rate and no re-admissions. Globally, major bleeding rates were 7.9% and 12.5%, thromboembolic events 3.7% and 12.5%, readmissions 37% and 25%, and mortality 22% and 25%, in HTx and LVADs respectively. No death was related to the implanted transcatheter device. CONCLUSIONS: Most centers with HTx/LVAD programs perform structural percutaneous procedures but with very inconsistent incidence. They were associated with good safety and efficacy, but larger studies are required to provide formal recommendations.
RESUMO
Systemic AL amyloidosis is a challenging disease for which many patients are considered frail in daily clinical practice. However, no study has so far addressed frailty and its impact on the outcome of these patients. We built a simple score to predict mortality based on three frailty-associated variables: age, ECOG performance status (<2 vs. ≥2) and NT-proBNP (<8500 vs. ≥8500 ng/L). Four-hundred and sixteen consecutive newly diagnosed patients diagnosed at ten sites from the Spanish Myeloma Group were eligible for the study. The score was developed in a derivation cohort from a referral center, and it was externally validated in a multicenter cohort. Multivariate analysis showed that the three variables were independent predictors of survival. The score was able to discriminate four groups of patients in terms of overall survival and early mortality in both cohorts. Comorbidity was also analyzed with the Charlson comorbidity index, but it did not reach statistical significance in the model. A nomogram was created to easily estimate the mortality risk of each patient at each time point. This score is a simple, robust, and efficient approach to dynamically assess frailty-dependent mortality both at diagnosis and throughout follow-up. The optimal treatment for frail AL amyloidosis patients remains to be determined but we suggest that the estimation of frailty-associated risk could complement current staging systems, adding value in clinical decision-making in this complex scenario.
RESUMO
Introducción y objetivos: Existe controversia acerca de los resultados del trasplante cardiaco en pacientes con miocardiopatía hipertrófica (MCH) o restrictiva (MCR). Métodos: Análisis retrospectivo de receptores adultos de un primer trasplante cardiaco entre 1984 y 2021 incluidos en un registro nacional. La mortalidad al primer y quinto año postrasplante en receptores con MCH y MCR se comparó con la de receptores con miocardiopatía dilatada (MCD). Resultados: Se incluyó a 3.703 pacientes (3.112 MCD; 331 MCH y 260 MCR) con seguimiento mediano de 5,0 años (3,1-5,0). En comparación con la MCD, el riesgo ajustado de mortalidad a 1 año fue: MCH: hazard ratio (HR)=1,38; intervalo de confianza del 95% (IC95%), 1,07-1,78; p=0,01, MCR: HR=1,48; IC95%, 1,14-1,93; p=0,003. El riesgo ajustado a 5 años fue: MCH: HR=1,17; IC95%, 0,93-1,47; p=0,18; MCR: HR=1,52; IC95%, 1,22-1,89; p<0,001. En los últimos 20 años, la MCR mejoró significativamente la supervivencia a 1 año (R2 ajustada=0,95) y a 5 años (R2=0,88); la MCH mejoró la supervivencia a 5 años (R2=0,59) y a 1 año permaneció estable (R2=0,16). Conclusiones: Se asoció la MCR y la MCH a peor pronóstico precoz postrasplante que la MCD. La diferencia desfavorable se mantuvo para la supervivencia a 5 años solo para la MCR. Se observa una tendencia temporal a mejor pronóstico precoz y tardío para la MCR, y solo para el tardío en la MCH. (AU)
Introduction and objectives: Posttransplant outcomes among recipients with a diagnosis of hypertrophic cardiomyopathy (HCM) or restrictive cardiomyopathy (RCM) remain controversial. Methods: Retrospective analysis of a nationwide registry of first-time recipients undergoing isolated heart transplant between 1984 and 2021. One-year and 5-year mortality in recipients with HCM and RCM were compared with those with dilated cardiomyopathy (DCM). Results: We included 3703 patients (3112 DCM; 331 HCM; 260 RCM) with a median follow-up of 5.0 [3.1-5.0] years. Compared with DCM, the adjusted 1-year mortality risk was: HCM: HR, 1.38; 95%CI, 1.07-1.78; P=.01, RCM: HR, 1.48; 95%CI, 1.14-1.93; P=.003. The adjusted 5-year mortality risk was: HCM: HR, 1.17; 95%CI, 0.93-1.47; P=.18; RCM: HR, 1.52; 95%CI, 1.22-1.89; P<.001. Over the last 20 years, the RCM group showed significant improvement in 1-year survival (adjusted R2=0.95) and 5-year survival (R2=0.88); the HCM group showed enhanced the 5-year survival (R2=0.59), but the 1-year survival remained stable (R2=0.16). Conclusions: Both RCM and HCM were linked to a less favorable early posttransplant prognosis compared with DCM. However, at the 5-year mark, this unfavorable difference was evident only for RCM. Notably, a substantial temporal enhancement in both early and late mortality was observed for RCM, while for HCM, this improvement was mainly evident in late mortality. (AU)

Introduction: We conducted a study to determine the prevalence of structural heart disease in patients with CF, the characteristics of a cardiomyopathy not previously described in this population, and its possible relationship with nutritional deficiencies in CF. Methods: We studied 3 CMP CF patients referred for heart-lung transplantation and a prospective series of 120 adult CF patients. All patients underwent a clinical examination, blood tests including levels of vitamins and trace elements, and echocardiography with evaluation of myocardial strain. Cardiac magnetic resonance imaging (CMR) was performed in patients with CMP and in a control group. Histopathological study was performed on hearts obtained in transplant or necropsy. Results: We found a prevalence of 10% (CI 4.6%-15.4%) of left ventricular (LV) dysfunction in the prospective cohort. Myocardial strain parameters were already altered in CF patients with otherwise normal hearts. Histopathological examination of 4 hearts from CF CMP patients showed a unique histological pattern of multifocal myocardial fibrosis similar to Keshan disease. Four of the five CF CMP patients undergoing CMR showed late gadolinium uptake, with a characteristic patchy pattern in 3 cases (p < 0.001 vs. CF controls). Selenium deficiency (Se < 60â µg/L) was associated with more severe LV dysfunction, higher prevalence of CF CMP, higher NTproBNP levels, and more severe pulmonary and digestive involvement. Conclusion: 10% of adults with CF showed significant cardiac involvement, with histological and imaging features resembling Keshan disease. Selenium deficiency was associated with the presence and severity of LV dysfunction in these patients.
RESUMO
Heart transplant (HT) remains the best therapeutic option for patients with advanced heart failure (HF). The allocation criteria aim to guarantee equitable access to HT and prioritize patients with a worse clinical status. To review the HT allocation criteria, the Heart Failure Association of the Spanish Society of Cardiology (HFA-SEC), the Spanish Society of Cardiovascular and Endovascular Surgery (SECCE) and the National Transplant Organization (ONT), organized a consensus conference involving adult and pediatric cardiologists, adult and pediatric cardiac surgeons, transplant coordinators from all over Spain, and physicians and nurses from the ONT. The aims of the consensus conference were as follows: a) to analyze the organization and management of patients with advanced HF and cardiogenic shock in Spain; b) to critically review heart allocation and priority criteria in other transplant organizations; c) to analyze the outcomes of patients listed and transplanted before and after the modification of the heart allocation criteria in 2017; and d) to propose new heart allocation criteria in Spain after an analysis of the available evidence and multidisciplinary discussion. In this article, by the HFA-SEC, SECCE and the ONT we present the results of the analysis performed in the consensus conference and the rationale for the new heart allocation criteria in Spain.

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.

Assessment of frailty before heart transplant (HT) is recommended but is not standard in most HT protocols. Our objective was to evaluate frailty at inclusion in HT list and during follow-up and to assess the influence of baseline frailty on prognosis. A prospective multicenter study in all adults included in the nonurgent HT waiting list. Frailty was defined as Fried's frailty phenotype score ≥3. Mean follow-up was 25.9 ± 1.2 months. Of 99 patients (mean age 54.8 [43.1 to 62.5] years, 70 men [70.7%]), 28 were frail (28.3%). A total of 85 patients received HT after 0.5 ± 0.01 years. Waiting time was shorter in frail patients (0.6 years [0.3 to 0.8] vs 0.2 years [0.1 to 0.4], p = 0.001) because of an increase in priority. Baseline frailty was not associated with overall mortality, (hazard ratio 0.99 [95% confidence interval 0.41 to 2.37, p = 0.98]). A total of 16 transplant recipients died (18.8%). Of the remaining 69 HT recipients, 65 underwent frailty evaluation during follow-up. Patients without baseline frailty (n = 49) did not develop it after HT. Of 16 patients with baseline frailty, only 2 were still frail at the end of follow-up. Frailty is common in HT candidates but is reversible in most cases after HT and is not associated with post-transplant mortality. Our results suggest that frailty should not be considered an exclusion criterion for HT.

Monoclonal gammopathies (MGs) are a wide range of diseases that may evolve or progress over time. Comorbidity plays a critical role in this setting. The co-occurrence of two MGs is not a rare event. The evidence on the association of systemic light chain (AL) amyloidosis and multiple myeloma (MM) is scarce and controversial. Herein we aim to address this topic in a large series of patients of a referral center. All consecutive AL amyloidosis patients treated at our center from January 2005 to April 2023 were prospectively enrolled in a clinical and epidemiological registry. 141 patients diagnosed with AL amyloidosis were included, of which 7 (5%) had localized whereas 134 presented with systemic disease. The heart was the most frequently affected organ (90.3%). 25 patients (18.7%) fulfilled the IMWG diagnostic criteria of MM (AL/MM). Time-dependent association between AL and MM showed that the synchronous pattern is more frequent than the appearance of a second primary malignancy. The diagnostic delay was six months (m). Patients with AL/MM had a poorer median overall survival (OS) than AL-only patients (35.5 m, CI 95% 0-88.9, vs. 52.6 m, CI 95% 16.7-88.5), but this difference was not statistically significant. The prognosis in AL is dominated by the heart involvement, which is massive in this series. In our Cox regression model, only three prognostic variables remain as independent prognostic factors: age, N-terminal pro-brain natriuretic peptide (≥8500 ng/L), and undergoing an autologous stem cell transplant, whereas left ventricular ejection fraction shows a marginal effect. More and large studies focusing on the AL/MM association are needed to uncover the characteristics and prognostic impact of this association.
RESUMO
OBJECTIVE: We sought to investigate prevalence, incidence and prognostic implications of permanent pacemaker (PPM) implantation in patients with cardiac amyloidosis (CA), thereby identifying the predictors of time to PPM implantation. METHODS: Seven hundred eighty-seven patients with CA (602 men, median age 74 years, 571 transthyretin amyloidosis (ATTR), 216 light-chain amyloidosis (AL)) evaluated at two European referral centres were retrospectively included. Clinical, laboratory and instrumental data were analysed. The associations between PPM implantation and mortality, heart failure (HF) or a composite endpoint of mortality, cardiac transplantation and HF were analysed. RESULTS: 81 (10.3%) patients had a PPM before initial evaluation. Over a median follow-up time of 21.7 months (IQR 9.6-45.2), 81 (10.3%) additional patients (18 with AL (22.2%) and 63 with ATTR (77.8%)) underwent PPM implantation with a median time to implantation of 15.6 months (IQR 4.2-40), complete atrioventricular block was the most common indication (49.4%). Independent predictors of PPM implantation were QRS duration (HR 1.03, 95% CI 1.02 to 1.03, p<0.001) and interventricular septum (IVS) thickness (HR 1.1, 95% CI 1.03 to 1.17, p=0.003). The model to estimate the probability of PPM at 12 months and containing both factors showed a C-statistic of 0.71 and a calibration of slope of 0.98. CONCLUSIONS: Conduction system disease requiring PPM is a common complication in CA that affects up to 20.6% of patients. QRS duration and IVS thickness are independently associated with PPM implantation. A PPM implantation at 12 months model was devised and validated to identify patients with CA at higher risk of requiring a PPM and who require closer follow-up.

In this observational and multicenter study, that included all patients who underwent a heart transplantation (HT) in Spain from 1984 to 2018, we analyzed the incidence, management, and prognosis of colorectal cancer (CRC) after HT. Of 6,244 patients with a HT and a median follow-up of 8.8 years since the procedure, 116 CRC cases (11.5% of noncutaneous solid cancers other than lymphoma registered) were diagnosed, mainly adenocarcinomas, after a mean of 9.3 years post-HT. The incidence of CRC increased with age at HT from 56.6 per 100,000 person-years among under 45 year olds to 436.4 per 100,000 person-years among over 64 year olds. The incidence rates for age-at-diagnosis groups were significantly greater than those estimated for the general Spanish population. Curative surgery, performed for 62 of 74 operable tumors, increased the probability of patient survival since a diagnosis of CRC, from 31.6% to 75.7% at 2 years, and from 15.8% to 48.6% at 5 years, compared to patients with inoperable tumors. Our results suggest that the incidence of CRC among HT patients is greater than in the general population, increasing with age at HT.

Introducción y objetivos El remodelado vascular pulmonar es prevalente en la insuficiencia cardiaca avanzada. El cateterismo derecho es la prueba de elección, pero está limitado por la asunción de medidas indirectas, un enfoque de flujo no pulsátil, su dependencia de la carga o la variabilidad en la interpretación. Nuestro objetivo es evaluar la vasculopatía pulmonar mediante tomografía de coherencia óptica (OCT) intravascular y correlacionarla con los parámetros hemodinámicos. Métodos Estudio observacional, prospectivo y multicéntrico que incluyó a 100 pacientes en estudio previo al trasplante cardiaco. Todos se sometieron a un cateterismo derecho con OCT de la arteria pulmonar. Resultados La OCT se pudo analizar en 90 casos. La mediana de edad fue 57,50 [intervalo intercuartílico, 48,75-63,25] años y 71 eran varones (78,88%). La cardiopatía subyacente más frecuente fue la miocardiopatía dilatada no isquémica (33 pacientes [36,66%]). El grosor intimal se correlacionó con la presión arterial pulmonar media, las resistencias vasculares y el gradiente transpulmonar (coeficiente R de 0,42, 0,27 y 0,32 respectivamente). La estimación no invasiva de la presión sistólica pulmonar, el tiempo de aceleración y el acoplamiento ventriculoarterial también se correlacionaron con el grosor intimal (coeficiente R de 0,42, 0,27 y 0,49 respectivamente). Los pacientes con un grosor intimal > 0,25mm presentaron mayores presión pulmonar media (37,00 frente a 25,00mmHg; p=0,004) y resistencias vasculares (3,44 frente a 2,08 UW; p=0,017). Conclusiones La OCT pulmonar es factible y está significativamente asociada con los datos hemodinámicos. La correlación débil indica que el remodelado vascular no explica por completo la hipertensión pulmonar (AU)
Introduction and objectives Pulmonary vascular remodeling is common among patients with advanced heart failure. Right heart catheterization is the gold standard to assess pulmonary hypertension, but is limited by indirect measurement assumptions, a steady-flow view, load-dependency, and interpretation variability. We aimed to assess pulmonary vascular remodeling with intravascular optical coherence tomography (OCT) and to study its correlation with hemodynamic data. Methods This observational, prospective, multicenter study recruited 100 patients with advanced heart failure referred for heart transplant evaluation. All patients underwent right heart catheterization together with OCT evaluation of a subsegmentary pulmonary artery. Results OCT could be performed and properly analyzed in 90 patients. Median age was 57.50 [interquartile range, 48.75-63.25] years and 71 (78.88%) were men. The most frequent underlying heart condition was nonischemic dilated cardiomyopathy (33 patients [36.66%]). Vascular wall thickness significantly correlated with mean pulmonary artery pressure, pulmonary vascular resistance, and transpulmonary gradient (R coefficient=0.42, 0.27 and 0.32 respectively). Noninvasive estimation of pulmonary artery systolic pressure, acceleration time, and right ventricle-pulmonary artery coupling also correlated with wall thickness (R coefficient of 0.42, 0.27 and 0.49, respectively). Patients with a wall thickness over 0.25mm had significantly higher mean pulmonary pressures (37.00 vs 25.00mmHg; P=.004) and pulmonary vascular resistance (3.44 vs 2.08 WU; P=.017). Conclusions Direct morphological assessment of pulmonary vascular remodeling with OCT is feasible and is significantly associated with classic hemodynamic parameters. This weak association suggests that structural remodeling does not fully explain pulmonary hypertension (AU)

BACKGROUND: Primary graft dysfunction (PGD) still affects 2% to 28% of heart transplants (HT). Severe PGD requires mechanical circulatory support (MCS) and is the main cause of death early after HT. Earlier initiation has been suggested to improve prognosis but the best cannulation strategy is unknown. METHODS: Analysis of all HT in Spain between 2010 and 2020. Early (<3 hours after HT) vs late initiation (≥3 hours after HT) of MCS was compared. Special focus was placed on peripheral vs central cannulation strategy. RESULTS: A total of 2376 HT were analyzed. 242 (10.2%) suffered severe PGD, 171 (70.7%) received early MCS and 71 (29.3%) late MCS. Baseline characteristics were similar. Patients with late MCS had higher inotropic scores and worse renal function at the moment of cannulation. Early MCS had longer cardiopulmonary bypass times and late MCS was associated with more peripheral vascular damage. No significant differences in survival were observed between early and late implant at 3 months (43.82% vs 48.26%; log-rank p = 0.59) or at 1 year (39.29% vs 45.24%, log-rank p = 0.49). Multivariate analysis did not show significant differences favoring early implant. Survival was higher in peripheral compared to central cannulation at 3 months (52.74% vs 32.42%, log-rank p = 0.001) and 1 year (48.56% vs 28.19%, log-rank p = 0.0007). In the multivariate analysis, peripheral cannulation remained a protective factor. CONCLUSIONS: Earlier MCS initiation for PGD was not superior, compared to a more conservative approach with deferred initiation. Peripheral compared to central cannulation showed superior 3-month and 1-year survival rates.

Introducción y objetivos Se presentan las características clínicas, los resultados y las complicaciones de todos los pacientes a los que se implantó un dispositivo de asistencia circulatoria mecánica de larga duración en España entre 2007 y 2020. Métodos Análisis a partir del Registro español de asistencia ventricular de larga duración (REGALAD) en el que participaron los centros españoles con programa de asistencia ventricular mecánica. Resultado En este periodo se implantaron 263 dispositivos de asistencia ventricular de larga duración en 22 hospitales. En 182 pacientes (69%) la asistencia fue ventricular izquierda de flujo continuo; en 79 (30%), de flujo pulsátil (58 izquierdas y 21 biventriculares), y en 2 (1%) se implantó un corazón artificial total. El objetivo de la asistencia fue el puente al trasplante en 78 pacientes (30%), puente a la candidatura en 110 (42%), puente a la recuperación en 3 (1%) y la terapia de destino en 72 (27%). La supervivencia total a 6, 12 y 24 meses fue del 79, el 74 y el 69% respectivamente, y la mejor se consiguió con las asistencias izquierdas de flujo continuo (el 84, el 80 y el 75%). Las principales complicaciones asociadas fueron: infecciones (el 37% de los pacientes), hemorragias (35%), neurológicas (29%) y disfunción de la asistencia (17%). Conclusiones Las asistencias ventriculares de larga duración han irrumpido en España como un tratamiento útil en la insuficiencia cardiaca avanzada. Como en otros registros internacionales, se tiende a utilizar dispositivos izquierdos intracorpóreos de flujo continuo, que se asocian con mejores resultados. Las complicaciones relacionadas siguen siendo frecuentes y graves (AU)
Introduction and objectives This report presents the clinical characteristics, outcomes and complications of all consecutive patients implanted with a long-term mechanical circulatory support device in Spain between 2007 and 2020. Methods Analysis of the Spanish Registry of durable ventricular assist devices (REGALAD) including data form Spanish centers with a mechanical circulatory support program. Results During the study period, 263 ventricular assist devices were implanted in 22 hospitals. The implanted device was an isolated continuous-flow left ventricular assist device in 182 patients (69%), a pulsatile-flow device (58 isolated left ventricular and 21 biventricular) in 79 (30%), and a total artificial heart in 2 patients (1%). The strategy of the implant was as bridge to heart transplant in 78 patients (30%), bridge to candidacy in 110 (42%), bridge to recovery in 3 (1%) and destination therapy in 72 patients (27%). Overall survival at 6, 12 and 24 months was 79%, 74% and 69%, respectively, and was better in continuous-flow left ventricular assist devices (84%, 80%, and 75%). The main adverse events related to this therapy were infections (37% of patients), bleeding (35%), neurological (29%), and device malfunction (17%). Conclusions Durable ventricular assist devices have emerged in Spain in the last few years as a useful therapy for patients with advanced heart failure. As in other international registries, the current trend is to use continuous-flow intracorporeal left ventricular devices, which are associated with better results. Adverse events continue to be frequent and severe (AU)
