Cardiology Flashcards
Indications for AVR
(THREE)
Severe symptomatic aortic stenosis
Severe symptomatic aortic regurgitation
Infective endocarditis
Mechanical vs bioprosthetic valve
Mechanical long lasting and durable
Mechanical requires life long anticoagulation with warfarin
Signs of severity in aortic stenosis
(FIVE)
Quiet second heart sound
Long duration of murmur
Low volume pulse
Forceful apex beat
Fourth heart sound
Differentials for ejection systolic murmur
(FOUR)
Aortic stenosis
Aortic sclerosis
HOCM
Mitral regurgitation in pansystolic murmur
Aortic stenosis vs pulmonary stenosis
(THREE)
Each loudest over respective areas
Aortic loudest expiration, pulmonary loudest inspiration
RV heave in pulmonary stenosis
Management of symptomatic aortic stenosis
(FIVE)
Referral to surgeons for valve replacement
Mechanical valve
Bioprosthetic valve
TAVI - transcatheter aortic valve implantation
Beta blockers
Avoid ACE-i, nitrates (increase gradient over valve)
Long term management of mechanical valves
(TWO)
Serial echos to monitor functions
Long term anticoagulation
Indications for MVR
(THREE)
Mitral stenosis
Mitral regurgitation
Infective endocarditis
Causes of new systolic murmur in MVR
Valve incompetence
New mumurs such as AS and TR
Signs of tricuspid regurgitation
(THREE)
Pansystolic murmur
Giant V waves in JVP
Left sternal thrill
Second heart sound in ASD
Fixed split second heart sound
All other causes of split second heart sound vary with respiration
Aortic stenosis murmur character
Crescendo-decrescendo
Ejection systolic
Loudest in aortic area
Loudest in expiration
Radiates to carotids
Mitral regurgitation murmur character
Pansystolic
Loudest at apex
Radiates to axilla
Loudest in expiration
Signs of severe MR
(FIVE)
Signs of pulmonary hypertension
Raised JVP
Loud P2
S3
Right ventricular heave
Displaced thrusting apex
Mitral regurgitation differentials
(THREE)
Mitral valve prolapse
Tricuspid regurgitation
VSD
Symptoms of MR
(THREE)
Dyspnoea
Reduced exercise tolerance
Fluid overload
Indications for mitral valve replacement
(FOUR)
Symptomatic mitral disease
Pulmonary hypertension/fluid overload
Declining ejection fraction
Acute MR following MI
Causes of MR
(FIVE)
Age related degeneration
Mitral prolapse (connective tissue disease eg Ehler’s Danlos)
Papillary muscle rupture (MI)
Rheumatic fever
Infective endocarditis
