RESUMEN
OBJECTIVES: This study aimed to evaluate the effectiveness of dalbavancin as sequential therapy in patients with infective endocarditis (IE) due to gram positive bacteria (GPB) in a real-life heterogenous cohort with comorbid patients. METHODS: A single center retrospective cohort study including all patients with definite IE treated with dalbavancin between January 2017 and February 2022 was developed. A 6-month follow-up was performed. The main outcomes were clinical cure rate, clinical and microbiological relapse, 6-month mortality, and adverse effects (AEs) rate. RESULTS: The study included 61 IE episodes. The median age was 78.5 years (interquartile range [IQR] 63.2-85.2), 78.7% were male, with a median Charlson comorbidity index of 7 (IQR 4-9) points. Overall, 49.2% suffered native valve IE. The most common microorganism was Staphylococcus aureus (26.3%) followed by Enterococcus faecalis (21.3%). The median duration of initial antimicrobial therapy and dalbavancin therapy were 27 (IQR 20-34) and 14 days (IQR 14-28) respectively. The total reduction of hospitalization was 1090 days. The most frequent dosage was 1500mg of dalbavancin every 14 days (96.7%). An AE was detected in 8.2% of patients, only one (1.6%) was attributed to dalbavancin (infusion reaction). Clinical cure was achieved in 86.9% of patients. One patient (1.6%) with Enterococcus faecalis IE suffered relapse. The 6-month mortality was 11.5%, with only one IE-related death (1.6%). CONCLUSION: This study shows a high efficacy of dalbavancin in a heterogeneous real-world cohort of IE patients, with an excellent safety profile. Dalbavancin allowed a substantial reduction of in-hospital length of stay.
RESUMEN
BACKGROUND AND METHODS: Heart transplant recipients (HTr) have a higher probability of suffer from severe coronavirus disease-2019 (COVID-19) in comparison to general population, but their risk has changed over the course of the pandemic in relation to various factors. We conducted a prospective study including all HTr at risk of COVID-19 in a tertiary center between February 2020 and October 2022. The aim was to analyze how the prognosis (incidence of pneumonia and mortality) of COVID-19 in HTr has evolved over time, contextualizing variants, vaccination, and other treatments. RESULTS: Of 308 HTr included, 124 got the infection (39.2%). COVID and non-COVID HTr had similar baseline characteristics. COVID-19 patients with pneumonia had a poorer prognosis than those with less severe presentations, with a higher rate of hospitalization (93.3 vs. 14.1%, p < .001) and death (41.0 vs. 1.2%, p < .001). Multivariate analysis identified age ≥60 years (odds ratio [OR] 3.65, 95% confidence interval [CI] 1.16-11.49, p = .027), and chronic kidney disease ≥3a (OR 4.95, 95% CI 1.39-17.54, p = .014) as predictors of pneumonia. Two-dose vaccination (OR 0.20, CI 95% 0.05-0.72, p = .02) and early remdesivir administration (OR 0.17, CI 0.03-0.90, p = .037) were protective factors. Over the course of the pandemic considering three periods in the follow-up (prevaccination February-December 2020, postvaccination January-December 2021, and post early remdesivir indication January-October 2022), we observed a reduction in pneumonia incidence from 62% to 19% (p < .001); and mortality (from 23% to 4%, p < .001). CONCLUSIONS: The prognosis of COVID-19 in HTr has improved over time, likely due to vaccination and early administration of remdesivir.

BACKGROUND AND AIMS: Benefit of tricuspid regurgitation (TR) correction and timing of intervention are unclear. This study aimed to compare survival rates after surgical or transcatheter intervention to conservative management according to a TR clinical stage as assessed using the TRI-SCORE. METHODS: A total of 2,413 patients with severe isolated functional TR were enrolled in TRIGISTRY (1217 conservatively managed, 551 isolated tricuspid valve surgery, and 645 transcatheter valve repair). The primary endpoint was survival at 2 years. RESULTS: The TRI-SCORE was low (≤3) in 32%, intermediate (4-5) in 33%, and high (≥6) in 35%. A successful correction was achieved in 97% and 65% of patients in the surgical and transcatheter groups, respectively. Survival rates decreased with the TRI-SCORE in the three treatment groups (all P < .0001). In the low TRI-SCORE category, survival rates were higher in the surgical and transcatheter groups than in the conservative management group (93%, 87%, and 79%, respectively, P = .0002). In the intermediate category, no significant difference between groups was observed overall (80%, 71%, and 71%, respectively, P = .13) but benefit of the intervention became significant when the analysis was restricted to patients with successful correction (80%, 81%, and 71%, respectively, P = .009). In the high TRI-SCORE category, survival was not different to conservative management in the surgical and successful repair group (61% and 68% vs 58%, P = .26 and P = .18 respectively). CONCLUSIONS: Survival progressively decreased with the TRI-SCORE irrespective of treatment modality. Compared to conservative management, an early and successful surgical or transcatheter intervention improved 2-year survival in patients at low and, to a lower extent, intermediate TRI-SCORE, while no benefit was observed in the high TRI-SCORE category.

INTRODUCTION: Estimation of peri-procedural risk in patients with tricuspid regurgitation (TR) undergoing isolated tricuspid valve surgery (ITVS) is of paramount importance. The TRI-SCORE is a new surgical risk scale specifically developed for this purpose, which ranged from 0 to 12 points and included eight parameters: right-sided heart failure signs, daily dose of furosemide ≥125 mg, glomerular filtration rate <30 mL/min, elevated bilirubin (with a value of 2 points), age ≥70 years, New York Heart Association Class III-IV, left ventricular ejection fraction <60% and moderate/severe right ventricular dysfunction (with a value of 1 point). The objective of the study was to evaluate the performance of the TRI-SCORE in an independent cohort of patients undergoing ITVS. METHODS: A retrospective observational study was performed in four centres, including consecutive adult patients undergoing ITVS for TR between 2005 and 2022. The TRI-SCORE and the traditional risk scores used in cardiac surgery (Logistic EuroScore (Log-ES) and EuroScore-II (ES-II)) were applied for each patient, and discrimination and calibration of the three scores were evaluated in the entire cohort. RESULTS: A total of 252 patients were included. The mean age was 61.5±11.2 years, 164 (65.1%) patients were female, and TR mechanism was functional in 160 (63.5%) patients. The observed in-hospital mortality was 10.3%. The estimated mortality by the Log-ES, ES-II and TRI-SCORE was 8.7±7.3%, 4.7±5.3% and 11.0±16.6%, respectively. Patients with a TRI-SCORE ≤4 and >4 had an in-hospital mortality of 1.3% and 25.0%, p=0.001, respectively. The discriminatory capacity of the TRI-SCORE had a C-statistic of 0.87 (0.81-0.92), which was significantly higher than both the Log-ES (0.65 (0.54-0.75)) and ES-II (0.67 (0.58-0.79)), p=0.001 (for both comparisons). CONCLUSION: This external validation of the TRI-SCORE demonstrated good performance to predict in-hospital mortality in patients undergoing ITVS, which was significantly better than the Log-ES and ES-II, which underestimated the observed mortality. These results support the widespread use of this score as a clinical tool.

BACKGROUND: The surgical approach for the treatment of a left ventricular assist device with severe infection may be controversial. MATERIAL & METHODS: We present the case of a patient implanted with a HeartWare™ HVAD as a bridge to transplant and chronic infection of the device by Pseudomonas who underwent a conservative partial treatment of the driveline tunnel and subsequently a heart transplantation and device removal were done. CONCLUSIONS: The two-step simplified approach allowed the patient to be transplanted in a short period of time, with the abdominal wall healed and almost two-thirds of the driveline subcutaneous tunnel sterilized.

Background: Allograft pathologies, such as valvular, coronary artery, or aortic disease, may occur early and late after cardiac transplantation. Cardiac surgery after heart transplantation (CASH) may be an option to improve quality of life and allograft function and prolong survival. Experience with CASH, however, has been limited to single-center reports. Methods: We performed a retrospective, multicenter study of heart transplant recipients with CASH between January 1984 and December 2020. In this study, 60 high-volume cardiac transplant centers were invited to participate. Results: Data were available from 19 centers in North America (n = 7), South America (n = 1), and Europe (n = 11), with a total of 110 patients. A median of 3 (IQR 2-8.5) operations was reported by each center; five centers included ≥ 10 patients. Indications for CASH were valvular disease (n = 62), coronary artery disease (CAD) (n = 16), constrictive pericarditis (n = 17), aortic pathology (n = 13), and myxoma (n = 2). The median age at CASH was 57.7 (47.8-63.1) years, with a median time from transplant to CASH of 4.4 (1-9.6) years. Reoperation within the first year after transplantation was performed in 24.5%. In-hospital mortality was 9.1% (n = 10). 1-year survival was 86.2% and median follow-up was 8.2 (3.8-14.6) years. The most frequent perioperative complications were acute kidney injury and bleeding revision in 18 and 9.1%, respectively. Conclusion: Cardiac surgery after heart transplantation has low in-hospital mortality and postoperative complications in carefully selected patients. The incidence and type of CASH vary between international centers. Risk factors for the worse outcome are higher European System for Cardiac Operative Risk Evaluation (EuroSCORE II) and postoperative renal failure.
RESUMEN
Placement of a pulmonary artery catheter is not a risk-free technique. Related incidents include ventricular arrhythmias, air embolisms, pulmonary artery perforation, infections, or catheter thrombosis. Herein the authors report a rare complication-the intracardiac knotting and its successful extraction using a percutaneous tracheostomy set in a hemodynamically compromised patient after a heart transplant.

Providing complex therapies such as extracorporeal membrane oxygenation (ECMO) during outbreaks of infectious diseases has singular challenges. The impact of the SARS-CoV-2 pandemic has implied a mentality change by force of circumstances, and cardiac surgery has not been stranger to this trend. The need to treat critically ill patients with an unknown evolution has compelled cardiovascular surgeons to decide whether or not to implant an ECMO system, despite the limited scientific evidence available in the context of COVID-19. To add some confusion, doubts were raised about its potential deleterious outcome in COVID-19 patients, due to its effect on lymphocyte counts and interleukin-6 concentrations. The care of the critically ill patient in a moment of national emergency in Spain took precedence over those possible formal doubts. The Spanish perspective on ventricular assist devices during and after the COVID-19 pandemic, focused on ECMO as a particular case of mechanical circulatory support, is presented. We address both the challenges posed by the pandemic and the organizational model established in Spain; changes in ECMO therapy and some lessons learned for the next outbreaks are also described. It is not about reinventing the wheel in each country; it is enough to learn from experience and take advantage of the knowledge generated by those who have already gone through similar situations in our environment.
