Commonest cause of right ventricular failure is ?
Correct Answer: Left ventricular failure
Description: Ans. is 'd' i.e., Left ventricular failureRight sided hea failureo Most common cause of right sided hea failure is left sided hea failure, i.e. right hea failure occurs as a consequence of left hea failure because left hea failure increases pressure in pulmonary circulation that produces an increased burden on the right side of the hea.o Left sided hea failure --> is pulmonary circulation pressure T burden to right atrium and ventricle -4 right sided hea failure.o Isolated right-sided hea failure most often occurs with chronic severe pulmonary hypeension and thus is called Cor-pulmonale.o Dilatation and hyperopy are confined to right atrium and ventricle.o The major morphological and clinical effects of pure right sided hea failure differ from those of left-sided hea failure because pulmonary congestion is minimal, while there is increased pressure and congestion in systemic veins and poal venous system. That results in ?l. Peripheral edema of dependent poion, especially ankle (pedal) and pretibial edema is a hallmark of right sided hea failure. Generalized massive edema may occur --> An asarca.Hepatic enlargement with centrilobular necrosis that may progress to cirrhosis --> Cardiac cirrhosis.Congestive splenomegaly.Pleural effusion (in contrast to left sided hea failure where pulmonary edema occurs).Pericardial effusion.Ascitieso Pulmonary edema is associated with LVF whereas pleural effusion is associated with RVF.
