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., (Copyright © 2024 The Author(s).

Background: Preservation solutions may be used intraoperatively during coronary artery bypass grafting (CABG) to flush and preserve vein grafts. The aim of this study is to evaluate the effect of DuraGraft, an endothelial damage inhibitor (EDI) preservation solution on major adverse cardiac events (MACEs) after CABG., Methods: We conducted an observational, prospective, longitudinal, single-center study that included patients who underwent isolated CABG. The cohort treated with an EDI was matched 1:1 with a control group treated with conventional vein preservation, and matching was adjusted for possible confounding factors through propensity score (PS) matching. Three years follow-up was conducted, and the occurrence of MACE [defined as all cause-death, acute coronary syndrome (ACS), and new unplanned revascularization] was analyzed using Kaplan-Meier method., Results: The study included 180 patients, 90 in each group. There were no significant differences in baseline characteristics across study groups. The EDI group had a significantly better event-free survival at 3 years (89% vs . 78%, log-rank test P=0.035), with an incidence rate ratio of 0.41 [95% confidence interval (CI): 0.16-0.96]. In the pre-specified subgroups analysis, the use of an EDI was associated with a significantly better event-free survival in diabetic patients (log-rank test P=0.041) and those with two or more saphenous vein grafts (log-rank test P=0.015)., Conclusions: The utilization of an EDI for vein flushing and storage after vein harvest in CABG procedures has been shown to significantly decrease the incidence of MACE at 3 years post-surgery. This protective effect is particularly notable in diabetic patients and in individuals who have multiple vein grafts., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-23-636/coif).

This is a consensus document of the Spanish Society of Cardiovascular Infections ( SEICAV ), the Spanish Society of Thoracic and Cardiovascular Surgery ( SECTCV ) and the Biomedical Research Centre Network for Respiratory Diseases ( CIBERES ). These three entities have brought together a multidisciplinary group of experts that includes anaesthesiologists, cardiac and cardiothoracic surgeons, clinical microbiologists, infectious diseases and intensive care specialists, internal medicine doctors and radiologists. Despite the clinical and economic consequences of sternal wound infections, to date, there are no specific guidelines for the prevention, diagnosis and management of mediastinitis based on a multidisciplinary consensus. The purpose of the present document is to provide evidence-based guidance on the most effective diagnosis and management of patients who have experienced or are at risk of developing a post-surgical mediastinitis infection in order to optimise patient outcomes and the process of care. The intended users of the document are health care providers who help patients make decisions regarding their treatment, aiming to optimise the benefits and minimise any harm as well as the workload.

Purpose: There is a lack of consensus about which endocarditis-specific preoperative characteristics have an actual impact over postoperative mortality. Our objective was the identification and quantification of these factors., Methods: We performed a systematic review of all the studies which reported factors related to in-hospital mortality after surgery for acute infective endocarditis, conducted according to PRISMA recommendations. A search string was constructed and applied on three different databases. Two investigators independently reviewed the retrieved references. Quality assessment was performed for identification of potential biases. All the variables that were included in at least two validated risk scores were meta-analyzed independently, and the pooled estimates were expressed as odds ratios (OR) with their confidence intervals (CI)., Results: The final sample consisted on 16 studies, comprising a total of 7484 patients. The overall pooled OR were statistically significant (p < 0.05) for: age (OR 1.03, 95% CI 1.00-1.05), female sex (OR 1.56, 95% CI 1.35-1.81), urgent or emergency surgery (OR 2.39 95% CI 1.91-3.00), previous cardiac surgery (OR 2.19, 95% CI 1.84-2.61), NYHA ≥ III (OR 1.84, 95% CI 1.33-2.55), cardiogenic shock (OR 4.15, 95% CI 3.06-5.64), prosthetic valve (OR 1.98, 95% CI 1.68-2.33), multivalvular affection (OR 1.35, 95% CI 1.01-1.82), renal failure (OR 2.57, 95% CI 2.15-3.06), paravalvular abscess (OR 2.39, 95% CI 1.77-3.22) and S. aureus infection (OR 2.27, 95% CI 1.89-2.73)., Conclusions: After a systematic review, we identified 11 preoperative factors related to an increased postoperative mortality. The meta-analysis of each of these factors showed a significant association with an increased in-hospital mortality after surgery for active infective endocarditis. Graph summary of the Pooled Odds Ratios of the 11 preoperative factors analyzed after the systematic review and meta-analysis.

Objectives: We assessed the prognostic utility of risk scores in surgery for infective endocarditis (IE) to evaluate their reliability in mortality risk prediction., Methods: An observational retrospective study was developed to include all patients who underwent surgery for active IE from 2002 to 2016. Classical and endocarditis-specific risk scores were calculated., Results: A total of 180 patients were included in the study. The 30-day mortality rate was 26.82% [95% confidence interval (CI) 20.26-33.20%]. Classical risk scores were confirmed to have a suboptimal prognostic ability. Therefore, 4 IE-specific risk scores were calculated. Discrimination was evaluated using the area under the receiver operating characteristic curve. It was 0.76 (95% CI 0.68-0.82) for the Society of Thoracic Surgeons-IE (STS-IE) score; 0.68 (95% CI 0.58-0.76) for the De Feo-Cotrufo score; 0.73 (95% CI 0.66-0.79) for the PALSUSE score and 0.65 (95% CI 0.57-0.72) for the Costa score. The STS-IE score had higher discrimination when compared with the De Feo-Cotrufo score (P = 0.055) and the Costa score (P = 0.024); however, there was no significant difference when we compared the STS-IE score with the PALSUSE score (P = 0.58). Calibration was assessed using the Hosmer-Lemeshow test; an adequate calibration was confirmed in all 4 scores., Conclusions: Specific risk scores had better prognostic performance than classical risk scores. The STS-IE score had the highest discrimination and was adequately calibrated. The PALSUSE score also showed optimal discrimination and calibration. The De Feo-Cotrufo score had a lower discrimination in our sample; however, the De Feo-Cotrufo score is recommended in the current guidelines. The Costa score had the lowest discrimination.

Aims: Surgery for infective endocarditis (IE) is associated with high mortality. Our objectives were to describe the experience with surgical treatment for IE in Spain, and to identify predictors of in-hospital mortality., Methods: Prospective cohort of 1000 consecutive patients with IE. Data were collected in 26 Spanish hospitals., Results: Surgery was performed in 437 patients (43.7%). Patients treated with surgery were younger and predominantly male. They presented fewer comorbid conditions and more often had negative blood cultures and heart failure. In-hospital mortality after surgery was lower than in the medical therapy group (24.3 vs 30.7%, p=0.02). In patients treated with surgery, endocarditis involved a native valve in 267 patients (61.1%), a prosthetic valve in 122 (27.9%), and a pacemaker lead with no clear further valve involvement in 48 (11.0%). The most common aetiologies were Staphylococcus (186, 42.6%), Streptococcus (97, 22.2%), and Enterococcus (49, 11.2%). The main indications for surgery were heart failure and severe valve regurgitation. A risk score for in-hospital mortality was developed using 7 prognostic variables with a similar predictive value (OR between 1.7 and 2.3): PALSUSE: prosthetic valve, age ≥ 70, large intracardiac destruction, Staphylococcus spp, urgent surgery, sex [female], EuroSCORE ≥ 10. In-hospital mortality ranged from 0% in patients with a PALSUSE score of 0 to 45.4% in patients with PALSUSE score >3., Conclusions: The prognosis of IE surgery is highly variable. The PALSUSE score could help to identify patients with higher in-hospital mortality., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

Introduction and Objectives: The treatment of severe symptomatic aortic stenosis has been revolutionized by the technique of transcatheter valve replacement. The purpose of this study was to present the outcomes and predictors of mortality in patients enrolled between 2010 and 2011 in the Transcatheter Aortic Valve Replacement National Registry., Methods: We collected 131 preprocedural, 31 periprocedural, and 76 follow-up variables, and analyzed the immediate implant success rate, the 30-day safety endpoint, and all-cause 30-day and mid-term (mean follow-up, 244 days) mortality., Results: From January 2010 to December 2011, a total of 1416 patients were included: 806 with Edwards valves and 610 with CoreValves. The implant success and 30-day mortality rates were 94% and 8%, respectively, without differences between types of valves and approaches. The 30-day safety endpoint and mid-term mortality rates were 14% and 16%, respectively, which were also similar between groups. The presence of comorbidities (renal failure, peripheral vascular disease, ejection fraction, and atrial fibrillation), the need for conversion to surgery, and at least moderate aortic regurgitation after transcatheter aortic valve implantation were identified as independent predictors of in-hospital and mid-term mortality., Conclusions: The prognosis of valve implant patients could be improved by including comorbidities in patient selection and by minimizing the degree of residual aortic regurgitation to optimize the results of the procedure., (Copyright © 2013 Sociedad Española de Cardiología.

Objectives: The purpose of this study was to compare the voltage-dependent K(+) currents of human cells of the right and left atria and determine whether electrical remodeling produced by chronic atrial fibrillation (CAF) is chamber-specific., Background: Several data point to the existence of interatrial differences in the repolarizing currents. Therefore, it could be possible that CAF-induced electrical remodeling differentially affects voltage-dependent K(+) currents in each atrium., Methods: Currents were recorded using the whole-cell patch-clamp in myocytes from left (LAA) and right atrial appendages (RAA) obtained from sinus rhythm (SR) and CAF patients., Results: In SR, LAA and RAA myocytes were divided in 3 types, according to their main voltage-dependent repolarizing K(+) current. CAF differentially modified the proportion of these 3 types of cells on each atrium. CAF reduced the Ca(2+)-independent 4-aminopyridine-sensitive component of the transient outward current (I(to1)) more markedly in the LAA than in the RAA. Therefore, an atrial right-to-left I(to1) gradient was created by CAF. In contrast, the ultrarapid component of the delayed rectifier current (I(Kur)) was more markedly reduced in the RAA than in the LAA, thus abolishing the atrial right-to-left I(Kur) gradient observed in SR. Importantly, in both atria, CAF increased the slow component of the delayed rectifier current (I(Ks))., Conclusions: Our results demonstrated that in SR there are intra-atrial heterogeneities in the repolarizing currents. CAF decreases I(to1) and I(Kur) differentially in each atrium and increases I(Ks) in both atria, an effect that further promotes re-entry., (Copyright (c) 2010 American College of Cardiology Foundation.
