Question

What is the possible cause of plop sound on chest auscultation in a patient with recent history of TIA?

1) Aortic stenosis
2) Mitral regurgitation
3) Pulmonary hypertension
4) Ventricular septal defect

Answer 1

A plop sound during chest auscultation may indicate mitral regurgitation, where blood flows backward due to improper closure of the mitral valve, causing a murmur.

Step-by-step explanation:

The plop sound heard on chest auscultation in a patient with a recent history of TIA could potentially be caused by mitral regurgitation. This condition occurs when the mitral valve does not close properly, leading to blood flowing backward into the left atrium (regurgitation), which can produce a murmur or distinct plop sound when examining the heart via auscultation.

Heart murmurs are sounds produced by the turbulent flow of blood around damaged or insufficiently closed heart valves. In the case of mitral regurgitation, the sound you describe could correspond to the prolapse or backward motion of the mitral valve cusps when they fail to seal hermetically, allowing a backward squirt of blood which generates such an acoustic phenomenon.

Murals are classified from grade 1 to 6, with a higher number indicating a louder murmur. A plop sound is characteristic of significant turbulent blood flow that might be depicted on an auscultogram or phonocardiogram if further analysis is needed, which records both normal and abnormal sounds emitted from the heart valves.
