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.
