    الوصف: OBJECTIVE: Preoperative atrial fibrillation (AF) increases risk of stroke, heart failure, and all-cause mortality after cardiac surgery. Despite encouraging results and guideline recommendations, surgical ablation (SA) for AF concomitant with other heart surgery remains low. In the current study we aimed to address the long-term mortality after SA concomitant with cardiac surgery. METHODS: This report pertains to the HEart surgery In atrial fibrillation and Supraventricular Tachycardia (HEIST) registry. We identified 20,765 adult patients (62% male) with preoperative AF who underwent conventional sternotomy heart surgery between 2010 and 2021 in 8 tertiary centers in Poland, Netherlands, and Italy. We used Cox proportional hazards models for computations and propensity score matching to minimize differences in baseline characteristics. RESULTS: Of included patients, 2755 (13.4%) underwent SA for AF. The highest rates of SA were observed for mitral interventions (mitral valve repair or replacement and tricuspid intervention, 25.2%), lowest for isolated coronary artery bypass grafting (6.2%). Patients in the SA group were younger (mean age 64.5 ± 9.0 years vs 68.7 ± 16.0 years; P < .001) and lower risk (mean European System for Cardiac Operative Risk Evaluation [EuroSCORE] II, 4.1 vs 5.7; P < .001). During the 11-year study period, there was a mortality reduction associated with SA (hazard ratio, 0.57; 95% CI, 0.52-0.62; P < .001). After propensity matching, 2750 pairs with similar baseline characteristics were identified. SA was associated with 16% mortality decline (hazard ratio, 0.84; 95% CI, 0.75-0.94; P = .003). CONCLUSIONS: In this multicenter, retrospective, propensity matched study, SA concomitant with other cardiac surgery was associated with improved long-term survival regardless of baseline surgical risk.

    الوصف: Cardiac stereotactic body radiotherapy is an emerging treatment method for recurrent ventricular tachycardia refractory to invasive treatment methods. The single-fraction delivery of 25 Gy was assumed to produce fibrosis, similar to a post-radiofrequency ablation scar. However, the dynamics of clinical response and recent preclinical findings suggest a possible different mechanism. The data on histopathological presentation of post-radiotherapy hearts is scarce, and the authors provide significantly different conclusions. In this article, we present unique data on histopathological examination of a heart explanted from a patient who had a persistent anti-arrhythmic response that lasted almost a year, until a heart failure exacerbation caused a necessity of a heart transplant. Despite a complete treatment response, there was no homogenous transmural fibrosis in the irradiated region, and the overall presentation of the heart was similar to other transplanted hearts of patients with advanced heart failure. In conclusion, our findings support the theorem of functional changes as a source of the anti-arrhythmic mechanism of radiotherapy and show that durable treatment response can be achieved in absence of transmural fibrosis of the irradiated myocardium.

    الوصف: Objectives: Although endorsed by international guidelines, complete revascularization (CR) with Coronary Artery Bypass Grafting (CABG) remains underused. In higher-risk patients such as those with pre-operative atrial fibrillation (AF), the effects of CR are not well studied. Methods: We analyzed patients' data from the HEIST (HEart surgery In AF and Supraventricular Tachycardia) registry. Between 2012 and 2020 we identified 4770 patients with pre-operative AF and multivessel coronary artery disease who underwent isolated CABG. We divided the cohort according to the completeness of the revascularization and used propensity score matching (PSM) to minimize differences between baseline characteristics. The primary endpoint was all-cause mortality. Results: Median follow-up was 4.7 years [interquartile range (IQR) 2.3-6.9]. PSM resulted in 1,009 pairs of complete and incomplete revascularization. Number of distal anastomoses varied, accounting for 3.0 + -0.6 vs. 1.7 + -0.6, respectively. Although early (< 24 h) and 30-day post-operative mortalities were not statistically different between non-CR and CR patients [Odds Ratio (OR) and 95% Confidence Intervals (CIs): 1.34 (0.46-3.86); P = 0.593, Hazard Ratio (HR) and 95% CIs: 0.88 (0.59-1.32); P = 0.542, respectively] the long term mortality was nearly 20% lower in the CR cohort [HR (95% CIs) 0.83 (0.71-0.96); P = 0.011]. This benefit was sustained throughout subgroup analyses, yet most accentuated in low-risk patients (younger i.e., < 70 year old, with a EuroSCORE II < 2%, non-diabetic) and when off-pump CABG was performed. Conclusion: Complete revascularization in patients with pre-operative AF is safe and associated with improved survival. Particular survival benefit with CR was observed in low-risk patients undergoing off-pump CABG.

    الوصف: Mechanical circulatory support (MCS) methods are used in patients with both acute and chronic heart failure, who have exhausted other options for pharmacological or surgical treatments. The purpose of their use is to support, partially or completely, the failed ventricles and ensure adequate organ perfusion, which allows patients to restore full cardiovascular capacity, prolonging their life and effectively improving its quality. The three most popular devices include an intra-aortic balloon pump (IABP), percutaneous assist devices (including Impella, TandemHeart), and venoarterial extracorporeal membrane oxygenation (VA-ECMO). A multidisciplinary approach with the special participation of the Heart Team is required to determine the proper MCS strategy, the choice of the supporting method, and the time of its use. The studies published so far do not allow us to determine which MCS method is the safest and the most effective. Thus, the site experience and accessibility of the method seem to matter most today. MCS finds particular application in patients with acute coronary syndromes complicated by refractory cardiogenic shock, as well as in patients with acute heart failure of the high potential for reversibility. It can also serve as a backup for percutaneous coronary interventions of high risk (complex and high-risk indicated percutaneous coronary intervention [PCI], complex and high-risk indicated PCI [CHIP]). The use of appropriate supportive drugs, precise hemodynamic and echocardiographic monitoring, as well as optimal non-invasive or mechanical ventilation, are extremely important in the management of a patient with MCS. The most serious complications of MCS include bleeding, thromboembolic events, as well as infections, and hemolysis.
