Location and Radiation
2nd right intercostal space going to right neck
What is aortic stenosis
Physiology of the Valsalva maneuver.
What is increasing intrathoracic pressure (reduces LV size-> decreases venous return to R heart-> L heart)
Pansystolic, blowing
What is mitral regurgitation
Closure of aortic/pulmonic valve
What is S2
Best diagnostic test for a heart murmur
What is an echo
Systolic at apex going into left axilla
What is mitral regurgitation (or prolapse)
Systolic murmur that increases with handgrip
What is mitral regurgitation
Harsh, crescendo-decrescendo,. As pathology progresses, the murmur will peak later in diastole.
What is aortic stenosis
Can be normal in kids and pregnancy
What is S3
Caused by rheumatic heart disease, diastolic rumbling
What is mitral stenosis
Systolic at 2nd and 3rd left intercostal space-> if loud will radiate towards left shoulder and neck
What is pulmonic stenosis
Squatting will shorten this murmur
What is MVP associated MR
What is a patent ductus arteriosus.
Closure aortic then pulmonic valve, increases w/inspiration
What is a physiological split
2 murmurs associated with Marfan's syndrome
What is MVP and AR
3rd or 4th left intercostal space-> down left sternal boarder to apex, not to the neck (atheletes)
What is hypertrophic cardiomyopathy
This murmur increases with Valsalva but decreases with squatting and isometric hand grip
What is hypertrophic obstructive cardiomyopathy or mitral valve prolapse
Blowing, decrescendo right after S2, leaning forward
What is aortic regurgitation.
Caused by LBBB, advanced aortic stenosis
What is a paradoxical split S2
Systolic murmur that is most often congenital
Pulmonic stenosis
Congential 3rd-5th left intercostal space that radiates widely. Often with a palpable thrill. Shunting from left to right
What is a VSD
Blowing, holosystolic murmur that increases in intensity with inspiration
What is tricuspid regurgitation
A loud, crescendo-decrescendo systolic murmur with widely split S2
What is pulmonic stenosis
2 causes of a fixed split S2
ASD, pulmonary HTN
Murmur from regurgitant jet prematurely closing a valve
What is an Austin-Flint murmur
