Question

The typical murmur associated with patent ductus arteriosus is:

A. Continuous murmur
B. Decreased diastolic murmur
C. Holosystolic murmur
D. Late systolic murmur

Answer 1

The typical murmur associated with patent ductus arteriosus is a continuous murmur, which can lead to heart complications if not treated.

Step-by-step explanation:

The typical murmur associated with patent ductus arteriosus (PDA) is a continuous murmur. This murmur is often referred to as a "machinery" murmur because of its continuous nature that occurs throughout both systole and diastole. PDA involves the failure of the ductus arteriosus, a vessel in the heart that allows blood to bypass the fetal lungs, to close after birth, resulting in the unusual blood flow that causes this distinct sound.

Treatment for PDA includes options such as surgical closure (ligation), manual closure using platinum coils or specialized mesh, or the use of nonsteroidal anti-inflammatory drugs to inhibit prostaglandin E2. If left untreated, PDA can lead to complications like congestive heart failure.
