STAGED ENDOVASCULAR TREATMENT OF ACUTE CORONARY SYNDROME AND AORTIC VALVE STENOSIS IN A PATIENT WITH HIGH RISK OF SURGICAL INTERVENTION ON THE "OPEN" HEART
Aortic stenosis (AS) is currently prevalent disease wherein there is a narrowing outlet of left ventricle (LV) and left ventricle blood ejection failure during systole. The prevalence of this pathology is about 0.5% in population and increases sharply among the group of patients older than 70 years and, is usually associated with age-related valve calcification. Gradual progressive disposition and thickening of the valve flaps leads to aortic valve opening narrowing. This results in a systolic pressure gradient between left ventricle and aorta.In 2002, an endovascular aortic valve prosthesis was created. This type of surgery has revolutionized the treatment of «non-operable» aortic stenosis. Transcatheter aortic valve replacement in Russia has been carried out since 2009, and to date quite a lot of experience has been accumulated using such technology. Especially severe course and the most unfavorable prognosis of this disease is observed in patients with combined acute coronary disease.
