Describe Aortic Stenosis Heart Murmurs	Crescendo-decrescendo systolic ejection murmur (ejection click may be present). LV >> aortic pressure during systole. Loudest at heart base; radiates to carotids. “Pulsus parvus et tardus”—pulses are weak with a delayed peak. Can lead to Syncope, Angina, and Dyspnea on exertion (SAD). Most commonly due to age-related calcification in older patients (> 60 years old) or in younger patients with early-onset calcification of bicuspid aortic valve.
In Aortic Stenosis, the murmur is loudest where? And where does it radiate to?	Loudest at heart base; radiates to carotids.
In Aortic Stenosis, the pulses are weak with a delayed what?	“Pulsus parvus et tardus”—pulses are weak with a delayed peak.
Aortic Stenosis can lead to what? What is the mnemonic device to remember?	Can lead to Syncope, Angina, and Dyspnea on exertion (SAD).

Describe Mitral Regurgitation Murmurs	Holosystolic, high-pitched “blowing murmur.” Mitral—loudest at apex and radiates toward axilla. MR is often due to ischemic heart disease (post-MI), MVP, LV dilatation. Rheumatic fever and infective endocarditis can cause either MR or TR.
Describe Tricuspid Regurgitation Murmurs	Holosystolic, high-pitched “blowing murmur.” Tricuspid—loudest at tricuspid area. TR commonly caused by RV dilatation. Rheumatic fever and infective endocarditis can cause either MR or TR.
What can cause either Mitral regurgitation or Tricuspid regurgitation?	Rheumatic fever and infective endocarditis can cause either MR or TR.

What commonly causes Tricuspid regurgitation?	TR commonly caused by RV dilatation.
Describe Mitral Valve Prolapse Murmurs	Late systolic crescendo murmur with midsystolic click (MC; due to sudden tensing of chordae tendineae). Most frequent valvular lesion. Best heard over apex. Loudest just before S2. Usually benign. Can predispose to infective endocarditis. Can be caused by myxomatous degeneration (1° or 2° to connective tissue disease such as Marfan or Ehlers-Danlos syndrome), rheumatic fever, chordae rupture.
What is the most frequent valvular lesion?	Mitral valve prolapse

What can mitral valve prolapse predispose someone to?	Can predispose to infective endocarditis.
What can mitral valve prolapse be caused by?	Can be caused by myxomatous degeneration (1° or 2° to connective tissue disease such as Marfan or Ehlers-Danlos syndrome), rheumatic fever, chordae rupture.
Describe Ventricular Septal Defect	Holosystolic, harsh-sounding murmur. Loudest at tricuspid area.
Where is a ventricular septal defect loudest?	Loudest at tricuspid area.
Describe Aortic Regurgitation Murmurs	High-pitched “blowing” early diastolic decrescendo murmur. Long diastolic murmur, hyperdynamic pulse, and head bobbing when severe and chronic. Wide pulse pressure. Often due to aortic root dilation, bicuspid aortic valve, endocarditis, rheumatic fever. Progresses to left HF.
What is aortic regurgitation often due to?	Often due to aortic root dilation, bicuspid aortic valve, endocarditis, rheumatic fever.
What does aortic regurgitation progress to?	Progresses to left HF
Describe Mitral Stenosis	Follows opening snap (OS; due to abrupt halt in leaflet motion in diastole, after rapid opening due to fusion at leaflet tips). Delayed rumbling mid-to-late diastolic murmur (decreased interval between S2 and OS correlates with increased severity). LA >> LV pressure during diastole. Often a late (and highly specific) sequela of rheumatic fever. Chronic MS can result in LA dilatation.
Mitral stenosis is often a late sequela of what?	Often a late (and highly specific) sequela of rheumatic fever.
Chronic mitral stenosis can result in what?	Chronic MS can result in LA dilatation.
