What are the traits of the murmur of mitral insufficiency?

Harsh, Blowing: Mitral valve prolapse is commonly caused by rheumatic heart disease. The murmur is harsh, blowing, and holosystolic radiating from the apex of the heart to the axilla. It has a characteristic midsystolic click. It is often asymptomatic but can cause difficulty breathing at night, with exertion, or when laying down. Diagnosis is made with an echocardiogram.

Mitral regurgitation: Is typically a holo systolic murmur best heard at the left lower sternal border or apex.

Systolic: It's holosystolic murmur that's loudest in the left lateral part of the chest and in the left axilla, louder with hand grip.
