The current research focuses on hemodynamic stresses and their impact on ventricular function. Heart failure caused by intrinsic myocardial injury causes high surgical mortality in valvular heart disease. When a patient survives surgery, his or her functional class frequently deteriorates, and intermediate-term mortality is significant. When heart failure is caused by excessive afterload and the myocardium is normal, however, reducing the afterload normalises ventricular function, lowers surgical mortality, and improves long-term survival. As this case indicates, by include afterload in the evaluation of these patients, death can be decreased and long-term survival can be greatly improved. Prospective studies are required to determine the best afterload cutoffs for predicting surgical mortality and long-term survival.
