Mitral Stenosis Diagnosis & Tests
A stethoscope examination reveals a distinctive murmur, snap, or other abnormal heart sound. The typical murmur is described as a "rumbling apical diastolic murmur with pre-systolic accentuation." This means a rumbling sound is heard over the point of the heart during the resting phase of the heart beat, and it gets more pronounced just before the heart contraction begins.
Examination may also reveal irregular heartbeat or lung congestion. Blood pressure is usually normal. There may be vibration (thrill), or a tapping sensation may be noted on palpation over the heart. Mitral stenosis may be difficult to distinguish from left atrial myxoma (a tumor of the heart).
Narrowing or obstruction of the valve or enlargement of the atrium may show on:
