Question

question 58 1 pts a patient has a cardiac murmur that peaks in mid - systole and is best heard along the left sternal border. the provider determines that the murmur decreases in intensity when the patient changes from standing to squatting and increases in intensity with the valsalva maneuver. which will the provider suspect is causing this murmur? aortic stenosis hypertrophic cardiomyopathy mitral valve prolapse tricuspid regurgitation

Explanation:

Hypertrophic cardiomyopathy murmur peaks in mid - systole, is best heard along the left sternal border, decreases with increased preload (standing to squatting which increases venous return) and increases with the Valsalva maneuver (decreases preload). Aortic stenosis murmur is usually a harsh crescendo - decrescendo systolic murmur but has different response to maneuvers. Mitral valve prolapse has a mid - systolic click and late systolic murmur. Tricuspid regurgitation murmur is a holosystolic murmur best heard at the lower left sternal border and changes with respiration rather than the described maneuvers.

Answer:

B. Hypertrophic cardiomyopathy
