Detailed explanation-1: -Mitral stenosis results in a uniquely shaped, low-pitched diastolic murmur best heard at the cardiac apex.
Detailed explanation-2: -One of the most common causes of a diastolic murmur is mitral stenosis. It is the most common manifestation of rheumatic heart disease, which is also the main etiology of mitral stenosis.
Detailed explanation-3: -A presystolic murmur or rumble of mitral stenosis precedes S1, a result of increased blood flow from atrial contraction. Following S2 (closure of the aortic and pulmonic valves) is the opening of the stenotic mitral valve (snap) and the low pitch middiastolic murmur or rumble of mitral stenosis.
Detailed explanation-4: -This type of murmur is a mid-diastolic rumbling murmur heard best over the apex. It is speculated to occur due to an aortic regurgitant jet causing the anterior mitral valve leaflet to close prematurely.
Detailed explanation-5: -The four most commonly encountered diastolic murmurs include aortic and pulmonary valve regurgitation, and mitral and tricuspid valve rumbles (Table 27.1). Compared to most systolic murmurs, diastolic murmurs are usually more difficult to hear, and certain auscultatory techniques are essential for their detection.
