Cardiovascular surgery and cardiology, current status of two sister specialties in Spain: the CARDIOXCARDIO study.

In recent years, there has been a notable shift in cardiovascular clinical practice within cardiology and surgery. The CARDIOXCARDIO study aimed to identify professionals' opinions on working practices and relations between specialties. A survey was simultaneously sent to the 4442 members of the Spanish Society of Cardiovascular and Endovascular Surgery (SECCE) and the Spanish Society of Cardiology (SEC), yielding 385 valid responses. More than half (59%) of respondents were men, mostly specialists (7.3% residents), and 74.8% worked in the field of cardiology, predominantly in public centers (88.3%). Using a Likert scale ranging from 1 to 5 (worst to best), respondents rated relations between surgery and cardiology with an average of 3.57±0.9 points. Cardiologists rated surgeons with a mean score of 3.83±0.8, while surgeons gave cardiologists a mean score of 3,92±0.72. In addition, respondents provided numerous suggestions for improvement, which are discussed in detail, highlighting certain discrepancies in criteria between specialties. Implementing strategies based on the suggestions of professionals, together with a proactive approach to continuous improvement, could substantially enhance the quality of cardiovascular care in Spain.

Spanish Heart Transplant Registry. 31th Official Report of the Heart Failure Association of the Spanish Society of Cardiology.

INTRODUCTION AND OBJECTIVES: The present report describes the clinical characteristics and outcomes of heart transplants in Spain and updates the data to 2019. METHODS: We describe the clinical characteristics and outcomes of heart transplants performed in Spain in 2019, as well as trends in this procedure from 2010 to 2018. RESULTS: In 2019, 300 transplants were performed (8794 since 1984; 2745 between 2010 and 2019). Compared with previous years, the most notable findings were the decreasing rate of urgent transplants (38%), and the consolidation of the type of circulatory support prior to transplant, with an almost complete disappearance of counterpulsation balloon (0.7%), stabilization in the use of extracorporeal membrane oxygenation (9.6%), and an increase in the use of ventricular assist devices (29.0%). Survival from 2016 to 2018 was similar to that from 2013 to 2015 (P=.34). Survival in both these periods was better than that from 2010 to 2012 (P=.002 and P=.01, respectively). CONCLUSIONS: Heart transplant activity has remained stable during the last few years, as have outcomes (in terms of survival). There has been a trend to a lower rate of urgent transplants and to a higher use of ventricular assist devices prior to transplant.

Evaluation of a nurse-led intervention program in heart failure: A randomized trial / Evaluación de un programa de intervención de enfermería en insuficiencia cardiaca: un ensayo aleatorizado

Background and objective: Several trials have evaluated the effect of disease management programs in heart failure (HF) with diverse results. The aim of this study was to develop a simple nurse-led clinic intervention program for patients with HF and assess whether this intervention positively affects the prognosis of patients, their care costs and perceived quality of life (QoL). Methods: Between 2011 and 2013, 127 patients with reduced ejection fraction were prospectively randomly allocated (1:2) to standard care or intervention program. Primary composite endpoint was all-cause mortality and hospital readmissions. Secondary endpoints were all-cause mortality, all-cause hospital readmissions, readmissions for HF, time to first readmission and QoL improvements assessed by "Minnesota Living with Heart Failure Questionnaire" (MLHFQ). An intention-to-treat analysis was performed. Results: After a median follow-up of 2-years, no differences were found in the primary composite endpoint. Likewise, there were no differences between groups in the predefined secondary endpoints of mortality and readmissions from any cause. However, in the intervention group, readmissions for HF were significantly reduced (35% vs. 18%; p=0.04) and QoL significantly improved (MLHFQ±SD: 2.29±14 vs. 10.9±14.75; p=0.04). Conclusions: In patients with HF, the use of a nurse-led intervention program significantly improves perceived QoL and reduce HF hospital readmissions

Introducción y objetivos: Se han publicado múltiples ensayos sobre programas de gestión de enfermedades en la insuficiencia cardiaca (IC) con resultados muy heterogéneos. El objetivo de este estudio fue desarrollar un sencillo programa de intervención clínica dirigido por enfermería en pacientes con IC y evaluar si dicha intervención afecta positivamente sobre el pronóstico de los pacientes, sus costes de atención y la calidad de vida percibida. Métodos: Entre 2011 y 2013, 127 pacientes con fracción de eyección reducida fueron aleatorizados (1:2) a manejo estándar o al programa de intervención. El objetivo primario compuesto fue mortalidad y reingresos hospitalarios por cualquier causa. Los criterios de valoración secundarios fueron mortalidad por cualquier causa, reingresos hospitalarios por cualquier causa, reingresos hospitalarios por IC, tiempo hasta el primer ingreso y mejoría de la calidad de vida evaluado por el Minnesota Living with Heart Failure Questionnaire (MLHFQ). Resultados: Tras un seguimiento medio de 2 años, no se encontraron diferencias en el criterio de valoración compuesto primario. Igualmente, no hubo diferencias en la mortalidad o los reingresos por cualquier causa. Sin embargo, en el grupo de intervención, los reingresos por IC se redujeron (35 vs. 18%; p=0,04) y la calidad de vida percibida mejoró de forma significativa (MLHFQ±DE: 2,29±14 vs. 10,9±14,75; p=0,04). Conclusiones: En los pacientes con IC, el empleo de un programa de intervención dirigido por enfermería mejora significativamente la calidad de vida percibida y reduce los reingresos hospitalarios por IC

Predicting Short- and Long-Term Outcomes in Adult Heart Transplantation: Clinical Utility of MELD-XI Score.

BACKGROUND: Model for End-Stage Liver Disease scoring system excluding international normalized ratio (MELD-XI) has been related with worse outcomes after heart transplantation (HT). However, according to standards in prognostic models research, before implementing a risk score for daily clinical decision-making, its performance and impact on clinical practice/outcomes should be evaluated. The aim of this study was to evaluate the ability of the MELD-XI score to predict outcomes in daily clinical practice. MATERIAL AND METHODS: We retrospectively reviewed 190 consecutive adults undergoing HT between 2005-2015. Patients were stratified into low (MELD-XI <12) and high (MELD-XI ≥12) risk cohorts. Mortality rates at 30 days and 1 year were compared between MELD-XI groups. MELD-XI ability to predict 1-year mortality was assessed by the area under the receiver operating curve (AUC) and compared to that of bilirubin, creatinine, and pulmonary vascular resistance (PVR). RESULTS: Mortality rates at 30 days and 1 year were similar between groups (8% vs 13%; P = .28 and 21% vs 29%; P = .21, respectively). MELD-XI ability to predict 1-year mortality was poor and similar to that of bilirubin, creatinine, and PVR (0.51 vs 0.47 vs 0.50 vs 0.50, respectively). CONCLUSIONS: MELD-XI score utility in HT clinical decision-making is scarce since its discrimination ability is poor and similar to other simple prognostic variables.

Cancer Incidence in Heart Transplant Recipients With Previous Neoplasia History.

Neoplasm history increases morbidity and mortality after solid organ transplantation and has disqualified patients from transplantation. Studies are needed to identify factors to be considered when deciding on the suitability of a patient with previous tumor for heart transplantation. A retrospective epidemiological study was conducted in heart transplant (HT) recipients (Spanish Post-Heart Transplant Tumor Registry) comparing the epidemiological data, immu-nosuppressive treatments and incidence of post-HT tumors between patients with previous malignant noncardiac tumor and with no previous tumor (NPT). The impact of previous tumor (PT) on overall survival (OS) was also assessed. A total of 4561 patients, 77 PT and 4484 NPT, were evaluated. The NPT group had a higher proportion of men than the PT group (p < 0.001). The incidence of post-HT tumors was 1.8 times greater in the PT group (95% confidence interval [CI] 1.2-2.6; p < 0.001), mainly due to the increased risk in patients with a previous hematologic tumor (rate ratio 2.3, 95% CI 1.3-4.0, p < 0.004). OS during the 10-year posttransplant period was significantly lower in the PT than the NPT group (p = 0.048) but similar when the analysis was conducted after a first post-HT tumor was diagnosed. In conclusion, a history of PT increases the incidence of post-HT tumors and should be taken into account when considering a patient for HT.

Light-chain-restricted germinal centres in reactive lymphadenitis: report of eight cases.

AIMS: Light-chain-restricted germinal centres are generally associated with the existence of a neoplastic lymphoproliferative disorder. The aim was to present a series of cases with persistent lymph node enlargement that featured some germinal centres showing light chain immunoglobulin restriction. METHODS AND RESULTS: A series of six reactive lymphadenitis and two Castleman's disease cases was analysed by immunohistochemistry, IgH-polymerase chain reaction (PCR) and microdissected PCR. In all cases some germinal centres contained a population of plasma cells and plasmacytoid germinal centre cells showing light chain immunoglobulin restriction. In three cases the monotypic cells also showed distinct Bcl-2 expression. Two of the cases showed a predominant IgH rearrangement on a florid polyclonal background and one had an IgH monoclonal rearrangement, as revealed by PCR. Microdissected germinal centre PCR revealed a dominant repeated band in one of three cases and in another case a non-repeated clonal peak was observed. One of the patients developed a follicular lymphoma, which became evident from a subsequent biopsy. CONCLUSIONS: These findings may be a manifestation of an underlying disorder in the regulation of the immune response, or an exaggeration of the germinal centre oligoclonal nature. This should be taken into account in the differential diagnosis of follicular hyperplasia.

Long-term persistence of molecular disease after histological remission in low-grade gastric MALT lymphoma treated with H. pylori eradication. Lack of association with translocation t(11;18): a 10-year updated follow-up of a prospective study.

BACKGROUND: Localized low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma can regress after Helicobacter pylori eradication, but IgV(H) gene monoclonality may persist. We studied the long-term histological and molecular follow-up of 24 patients and the possible association of t(11;18) with the persistent monoclonality. PATIENTS AND METHODS: From January 1994, 24 untreated patients with stage I low-grade gastric MALT lymphoma associated with H. pylori were prospectively studied. They all received eradication treatment and were sequentially followed-up with endoscopies for histological and molecular studies. Rearrangement of the IgV(H) gene was studied by PCR analysis. MALT1 locus alterations were studied by FISH. RESULTS: Twenty-two of the 24 patients (91%) achieved disappearance of the lymphoma. Eighteen (82%) of the 22 histologically cured patients and 16 of the 19 (84%) with long follow-up had monoclonality. Three patterns of development of IgV(H) gene rearrangements were observed: four patients (21%) had polyclonal rearrangements; eight (58%) had maintained/intermittent monoclonality and four (21%) had occasional monoclonality, mostly after H. pylori reinfection. Only one patient (6%) with persistent monoclonality relapsed. The remaining 18 patients maintained the remission, despite the persistent monoclonality in 15, for a median of 66 months (range 20-113). t(11;18) was not found in any of the patients with persistent monoclonality. Time and the number of endoscopies performed were not related with the occurrence of monoclonality. CONCLUSIONS: In stage I low-grade gastric MALT lymphoma eradication of H. pylori achieves prolonged histological remission in 90% of patients, but molecular remission is not accomplished in most cases. Molecular disease persists for years, but is not associated with t(11;18).

Randomized comparison of efficacy of cooled tip catheter ablation of atrial flutter: anatomic versus electrophysiological complete isthmus block.

There is a subset of patients with failed ablation of the cavotricuspid isthmus (CTI) using standard catheters and with 10% of the patients having recurrences. The purpose of this study was to compare the cooled and standard ablation with regard to acute successful electrophysiological achievement of bidirectional isthmus block and the subacute anatomic characteristics of the lesions. This randomized, experimental study compares the effects of ablation on the isthmus using a cooled catheter with those of a standard ablation catheter in 16 pigs. In 12 animals, CTI block was achieved after ablation (8/8 cooled and 4/8 standard). In two animals, it was not possible to achieve complete isthmus block and two had persistent slow conduction (all four using the standard catheter). After 1 week, the animals were slaughtered. The size of the lesion was greater with the irrigated tip catheters. Transmural lesions were found in 14 animals. A complete line of anatomic isthmus block was not documented after thefirst line in six animals, four with the standard and two with the cooled catheter. A conduction block was never present across gaps > or = 5 mm. In conclusion cooled catheters achieved a complete line of electrophysiological and anatomical block in a significantly higher percentage than the standard catheters.

[Macroscopic and microscopic study of the right coronary artery after radiofrequency catheter ablation of cavotricuspid isthmus in an experimental model]. / Estudio macro y microscópico de la arteria coronaria derecha tras ablación con catéter y radiofrecuencia del istmo cavotricuspídeo en un modelo experimental.

INTRODUCTION AND OBJECTIVES: The right coronary artery (RCA) is found in the AV groove, just below the ablation target of atrial flutter, the cavotricuspid isthmus (ICT). After radiofrequency (RF) ablation with standard catheters, there have been no reports of complications, but it may not be successful in 10% of the cases. However, the use of irrigated tip catheters, which create deeper lesions, might potentially damage the coronary tree. METHODS: We analyzed the effects of ICT RF ablation on the coronary tree, with macroscopic and microscopic anatomopathological study. Ablation on ICT was performed using an irrigated tip catheter in 16 pigs and was randomly compared with a standard ablation catheter. There were no clinical problems, modifications of ST or new arrhythmias during the ablation. The heart was extracted at 1 week. RESULTS: The macroscopic study demonstrated that the right coronary artery was preserved, along the ICT, surrounded by the epicardial fat. The microscopic study showed an inflammatory reaction in the epicardial fat that reached the adventitia of the coronary artery, but never produced necrosis in 14 cases. The muscular wall of the artery had signs of focal inflammation without endothelium involvement in 2 cases. However, we found a subepicardial vein completely damaged by the radiofrequency. CONCLUSIONS: Although the right coronary artery is located just below the isthmus, no necrosis was observed in any case. However, there was an inflammatory reaction that focally reached the muscular wall. The veins may be damaged in RF ablation, perhaps due to the different blood flow of each vessel.
