Multivessel Coronary Disease and Severe Atherosclerotic Aorta: Real-World Experience.

Background and Objectives: Surgical revascularisation of patients with atherosclerosis of the ascending aorta remains a challenge. Different surgical strategies have been described in coronary surgical patients to offer alternative revascularisation strategies other than the conventional surgical revascularisation in patients unsuitable for it. The aim of this study is to compare the real-world outcomes between two groups of patients who underwent off-pump surgery (left internal mammary artery graft to the left anterior descending artery) or a hybrid with a percutaneous revascularisation procedure at a later stage. Materials and Methods: This is a single-centre retrospective observational study. Between the years 2010 and 2021, 91/6863 patients (1.33%) were diagnosed with severe atherosclerosis of the ascending aorta. All the patients were treated with off-pump revascularisation (91 patients), and the cardiologist would decide at a later stage whether the rest of the vessels would be treated with percutaneous revascularisation (25 patients). Results: There was no statistical difference in the various preoperative characteristics, except for coronary artery left main disease (30.30% vs. 64%; p = 0.0043). The two groups had no statistical differences in the perioperative characteristics and postoperative complications. The 1-, 5-, and 10-year mortality rates in the two groups were 6.1% vs. 0%, 59% vs. 80%, and 93.9% vs. 100%, respectively (off-pump vs. hybrid with percutaneous revascularisation procedure, p = 0.1958). Conclusions: Both strategies have high long-term comparable mortality. The off-pump surgery and the HCR procedure at a later stage may be solutions for these high-risk patients, but the target treatment should be complete HCR revascularisation during the index hospitalization.

Adult cardiac surgery report 2021: The annual report from the Registry of the National Institute of Cardiovascular Diseases.

INTRODUCTION: Based on a longtime voluntary registry founded by the Ministry of Healthcare of the Slovak Republic in 2012 and endorsed by the National Institute of Cardiovascular Diseases, well-defined data of all adult cardiac surgery procedures performed during the year 2021 are analyzed. MATERIAL AND METHOD: For this period, data on 947 procedures were submitted to the registry. RESULTS: The unadjusted in-hospital survival rate for the 352 isolated coronary artery bypass grafting procedures including urgent and emergency procedures (relationship on-/off pump 3.8 : 1) was 96.3 %. For 331 isolated heart valve procedures (33 transcatheter interventions), it was 95.5 %. Concerning ventricular assist devices, 19 implantations were registered. In 2021 the number of isolated heart transplantations was 16, which is a decrease by 38.5 % as compared to the previous year. CONCLUSION: These annually registered data are collected from voluntary public reporting and accumulate actual information on nearly all heart procedures carried out in the National Institute of Cardiovascular Diseases. These data capture advancements in heart medicine and represent the basis for quality management. In addition, the registry demonstrates that the provision of cardiac surgery in Slovakia is up to date, appropriate, and nationwide patient treatment is guaranteed all the time (Tab. 14, Fig. 2, Ref. 5).

Effect of intraluminal thrombus on growth rate of abdominal aortic aneurysms.

BACKGROUND: Abdominal aortic aneurysm (AAA) includes a variety of morphologies with changing properties. Growth rate is one of the most important factors directly linked to the risk of rupture. Intraluminal thrombus (ILT) covering aortic wall is found in the majority of AAAs. Yet, its role in biomechanical processes in AAA remains unclear. From one point of view ILT can serve as protective factor in reducing wall stress of AAA and thus slow down the growth. Modern concept of multilayered ILT proved active inflammatory processes inside, that can significantly affect the quality of the wall and thus lead to a higher growth rate and higher risk of rupture. The goal of this study was to analyze the effect of ILT on growth rate of AAA and support one of these theories. METHODS: Retrospective study of computed tomography angiography scans of AAA of 26 patients was performed. Forty pairs of consecutive scans have been analyzed. Periods between two scans varied. Maximal infrarenal diameter of AAA and size of ILT were measured. AAAs were split into 4 groups according to their initial diameter. Growth rate was calculated for each AAA and linked to the relative size of ILT. These values were statistically evaluated. RESULTS: Negative correlation between relative size of ILT and growth rate was found (P=0.042062). This significant result proved that thicker thrombus slowed down the growth of AAA and vice versa, smaller relative size of ILT was linked to higher growth rate. CONCLUSIONS: This finding shows importance of ILT as one of the key factors influencing biomechanical processes inside an AAA. Results of this study may contribute to future researches of this topic.
