[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.

[Aortic valve replacement via J-shaped partial upper sternotomy: randomized trial, mid-term results]. / Effektivnost' i bezopasnost' protezirovaniya aortal'nogo klapana cherez «mini-J¼ sternotomiyu: randomizirovannoe issledovanie, sredne-otdalennye rezul'taty.

OBJECTIVE: To evaluate the effectiveness and safety of aortic valve replacement through upper partial J-shaped sternotomy compared to conventional sternotomy. MATERIAL AND METHODS: There were 240 procedures of isolated aortic valve replacement for the period 2012-2017. According to inclusion criteria, 112 patients were randomized into 2 groups: group I - median sternotomy, group II - upper partial J-shaped sternotomy. Mean age of patients was 56.1±14.3 and 53.1±14.9 years, respectively (p=0.284). Females prevailed in both groups (55.4% vs. 57.1%, p=0.848). Peak pressure gradient on the aortic valve was 106.2±23.9 and 102.8±25.3 mm Hg, respectively (p=0.484). RESULTS: In-hospital mortality was 1.8% (n=1) in group I (p=0.315). Incidence of postoperative complications (complete atrioventricular blockade, ventricular septal defect) was similar (p=1.0). Mean time cross clamping in I and II groups was 65.5±12.5 and 64.7±13.1 min (p=0.729). Mean follow-up period was 31.6 and 33.5 months, respectively. Kaplan-Meier survival rate was 92.6 and 93.0%, respectively (log-rank test=0,767). Freedom from thromboembolic events was 91.7 and 90% (log-rank test=0.213). CONCLUSION. U: Pper partial J-shaped sternotomy is safe and effective for aortic valve surgery and characterized by similar outcomes compared to conventional sternotomy.
