Combined interventional method of air-plasma flow and exogenous nitric oxide for the debridement of intracardiac infectious sites

Prosthetic valve endocarditis is a clinically severe pathology, which, unless timely treated, rapidly leads to the development of heart failure. The severity of the disease is caused by the fact that the microorganisms and toxins bypass biological barriers and constantly enter the bloodstream, which subsequently results in sepsis with the development of systemic embolism and multiple organ failure. The conservative antibiotic therapy is often ineffective due to the location of the infectious focus in the avascular zone. The operations for prosthetic infectious valve endocarditis are technically challenging and require high qualifications of the operating surgeon. The article presents a clinical case of surgical treatment for infectious prosthetic endocarditis of the aortic valve. The combined treatment with air-plasma flow and exogenous nitric oxide (NO) using the Plazon device without any antiseptic solutions was used as a method for the debridement of infectious site.
