Question

Quizplus · Accepted Answer

MVP stands for mitral valve prolapse, which occurs when one or both cusps of the valve on the left side of the heart bulge back into the left atrium during systole. A is incorrect because AS refers to aortic stenosis, which is a narrowing of the aortic valve. B is incorrect because TS refers to tricuspid stenosis, which is a narrowing of the tricuspid valve. C is incorrect because MS refers to mitral stenosis, which is a narrowing of the mitral valve, but does not involve prolapse of the cusps.
