[Acute myocardial infarction and cardiogenic shock in patient with COVID-19].

The conditions of the pandemic caused by the novel coronavirus infection (COVID-19) are associated with overloading intensive care units, conversion of hospitals, and changes in routing of patients with acute cardiovascular pathology. At the same time, medical practice is still challenged to provide medical care to patients with acute coronary syndrome (ACS). Patients with COVID-19 and acute myocardial infarction (AMI) are at a higher risk of death while the incidence of this combination of diseases will be growing. This article describes a case of diagnosis and treatment of COVID-19 in a 69-year-old patient who was urgently hospitalized with cardiogenic shock associated with ACS, electrocardiographic signs of complete left bundle branch block, and left ventricular ejection fraction of 19 %. Coronary angiography with stenting was successfully performed in the conditions of extracorporeal membrane oxygenation. The patient received long-term intensive therapy in the intensive care unit followed by symptomatic treatment in the cardiac surgery unit. The patient's condition gradually improved and he was discharged from the hospital on the 56th day. The strategy of intensive care and active follow-up helped saving life of the patient with COVID-19 and AMI.

Early surgical myocardial revascularization as an effective method of treating patients with acute coronary syndrome. / Ranniaia khirurgicheskaia revaskuliarizatsiia miokarda kak éffektivnyi metod lecheniia patsientov s ostrym koronarnym sindromom.

BACKGROUND: One of the main methods of treating patients with acute coronary syndrome (ACS) is percutaneous coronary intervention (PCI), however in patients with multivascular, abnormal, or technically complicated coronary lesions, early surgical myocardial revascularization is more promising. Despite modern development of surgical and interventional techniques, the application of one strategy for all patients with acute coronary syndrome is problematic and should be based on the heart team's decision and patient data. AIM: The study was aimed at assessing the results of early surgical myocardial revascularization in patients with acute coronary syndrome. PATIENTS AND METHODS: Retrospectively with continuous sampling the study included 342 patients who underwent surgical treatment of acute coronary syndrome at the Federal Centre of High Medical Technologies from January 1st, 2014 to December 31st, 2018. Myocardial revascularization using two internal thoracic arteries was performed in 220 (64.3%) cases. The mean age of the patients was 64.2±10.8 years. Prevailing in the study were men - 69.3%. The average number of affected vessels amounted to 3.1±0.9. Fifty-six (16.4%) patients had cardiogenic shock at the time of operation, with 9 (2.6%) patients diagnosed as having severe mitral insufficiency and 5 (1.5%) with interventricular septal defect. All patients were on antiplatelet therapy. RESULTS: In-hospital mortality was 5.2% (18 patients). The mean time of operation amounted to 205.3±58.9 min, with that of artificial circulation to 57.9±13.2 min. Such complication as postoperative haemorrhage was observed in 20 cases (5.8%). The average volume of drainage losses amounted to 507.3±66.7 ml. The average length of stay in the ICU was 3.8±1.4 days, with that of hospital stay being 16.6±2.1 days. Twenty-seven (7.9%) patients after removal of drainages were diagnosed as having exudative pericarditis which resolved on the background of medicamentous therapy. CONCLUSION: Early surgical myocardial revascularization in patients with acute coronary syndrome may be performed safely and effectively, and should be considered individually in each patient by the heart team.

[Immediate and intermediate results of staged carotid endarterectomy in combination with coronary artery bypass grafting]. / Neposredstvennye i sredneotdalennye rezul'taty étapnykh operatsii na sonnykh arteriiakh v sochetanii s koronarnym shuntirovaniem.

The purpose of our investigation was to evaluate the immediate and intermediate results of staged operations of carotid endarterectomy and coronary artery bypass grafting in patients with multifocal atherosclerosis. We analysed a total of 475 operations. Of these, 371 (78.1%) patients underwent staged interventions (stage 1 - carotid endarterectomy, stage 2 - coronary artery bypass grafting). No neurological complications were observed after stage 1. Five (1.3%) patients developed cardiac arrhythmia in the form of atrial fibrillation, 7 (1.9%) were found to have transient neuropathy of cranial nerves. There were no lethal outcomes. Stage 2 was carried out 16±13 days after carotid endarterectomy. Of complications encountered, mention should be made of perioperative myocardial infarction in 1 (0.3%) patient, with 2 (0.6%) patients requiring emergency coronary bypass angiography. Newly onset atrial fibrillation was registered in 71 (19.1%) patients, haemorrhage followed by resternotomy in 6 (1.6%), and purulent wound complications in 4 (1.1%) patients. Death occurred in 1 (0.3%) patient. We also analysed the mid-term postoperative results (up to 32 months). The coverage amounted to 151 patients. The incidence rate of major adverse cardiac and cerebrovascular events (MACCE) was 6% (myocardial infarction - 2, acute cerebral ischaemia - 1, repeat myocardial revascularization - 5, lethal outcome - 1). Based on the obtained findings it may be concluded that staged operations on the carotid basin and coronary arteries by the number of complications are comparable to those after isolated coronary artery bypass grafting.

[Minimally invasive operations for varicose disease of lower extremities].

The authors discuss specific using minimally invasive surgical technique of ablation of the saphenous vein trunks by a modified Oesch PIN stripper method proposed by the authors. An experience with surgical treatment of 245 patients with varicose veins using the same modified technique is analyzed. Postoperative complications and medium-term results are evaluated.
