Cardio Murmurs


Mitral Regurgitation left sided heart failure, increase with expiration, problem closing valve during systole; holosystolic high pitched "blowing murmur" loudest at apex; MVP most common radiates to axilla
Tricuspid Regurgitation right sided heart failure; increase with inspiration; problem closing valve during systole; holosystolic high pitched "blowing murmur"; increase preload; best heard at left parasternal border, IV drug user; carcinoid heart disease; pulsatile liv
Aortic Regurgitaion Problem in closing diastole; increase LV EDV = increase frank starling mechanism; drop in diastolic pressure; "immediate high pitched blowing murmur"; involuntary head bobbing; isolated aortic valve root dialation
Mitral Stenosis problem opening valve in diastole, recurrent attacks of rheumatic fever; narrowing of mitral valve orifice; LA becomes dilated (due to increase ventricular feeling)>>>LV increase in PCWP =LA pressure; Low pitched mid to late diastolic rumble at apex. Open
Tricuspid Stenosis Problem opening valve in diastole; low pitched diastolic murmur often confused with MS; Murmur louder in inspiration which differentiates from MS
Aortic stenosis problem opening valve in systole; common cause of calcification of bicuspid valve; age related sclerosis valve; chronic RF; crescendo decrescendo murmur, radiates to carotids and apex; pulse weak compared to heart sounds "pulsus parvus et tardus' Diamond
MVP[mitral valve prolapse] late systolic murmur with midsystolic click; myoxamaotous degeneration of mitral valve leaflets "floppy valves" decrease preload --> hear S1 sound ; increase in preload--> hear S2 sound
ASD diastolic: wide fixed split S2 and loud S1; midsystolic ejection murmur, tricuspid rumble
VSD Harsh holosystolc murmur heard diffusely over the pericardium maximally
PDA Continous machine murmur heard at 2nd left space
Opens during systole Closes in diastole Aortic and Pulmonic
Opens in diastole and closes in systole Mitral and Tricuspid
Regurgitations problems closing valves
Stenosis Problems in stenosis
