Afterload it’s importance in surgical decision making in severe aortic stenosis

Abstract

The present study investigates the role of hemodynamic afterload in severe aortic stenosis and its influence on ventricular function. In this disease, heart failure due to intrinsic myocardial damage causes high surgical mortality. When the patient survives the surgical time; functional class deteriorates frequently in medium-term and mortality is also high. On the other hand, when heart failure is due to excessive afterload and normal myocardial structure, reducing excessive afterload is supposed to normalize ventricular function, reduce surgical mortality, and improve long-term survival. In this prospective study we tried to demonstrate the value of ventricular afterload on surgical prognosis in tight aortic valve stenosis in immediate and medium-term..
