Aortic valve regurgitation is a condition where there is insufficient closure of the aortic valve. As the valve is not closed tightly, the pumped-out blood is leaked back into the ventricular chamber. Fatigue, shortness of breath, weakness, chest pain, arrhythmia, etc., are the symptoms of aortic regurgitation. Congenital valve diseases, endocarditis, rheumatic fever, etc., are its causes. Valve replacement is the treatment for aortic valve regurgitation.
