A patient with aortic regurgitation is seen in the clinic for a regular checkup. The nurse assesses the patient and hears an Austin Flint murmur, which is heard best in which location?

Explanation

• An Austin Flint murmur is best heard over the apex of the heart. It is described as low-pitched and rumbling and can be heard during mid to late diastole. This murmur is associated with severe aortic regurgitation

• Incorrect: The second intercostal space on the left sternal border is the best location for hearing pulmonic stenosis

• Incorrect: The second intercostal space on the right sternal border is the best location for hearing aortic stenosis

• Incorrect:  Carotid arteries can produce a bruit if occluded, which may sound like a murmur. Aortic stenosis murmurs may also at times radiate to the carotid arteries
