Finals - PACES Flashcards
Cardiac - inspection
Scars / medications
Sternotomy scar
CABG / valve placement
Bruising
fall - cardiac origin with anti-coagulations
with Valves - metallic e.g. warfarin
Pitting oedema
evidence of cardiac failure
Observation cardiac
warfarin, bruising, sternotomy scar, saphenous graft scar, audible click, oedematous ankles
No scar
Valvular - Pulse, BP and heart sounds
AF - “”
CCF - JVP, lungs, oedema
Normal pulse and no warfarin
exclude AF
Auscultation - ESM
Aortic stenosis or aortic sclerosis
Pulse, BP, radiation & Apex beat
with no warfarin, normal pulse and no scar
check for CCF - JVP, lungs, oedema
Pulse character of aortic stenosis
slow rising pulse - blood moving slower rate due to stenosis - only in severe aortic stenosis
narrow pulse pressure - systolic similar to diastolic - 25% of difference between the two or less
Systolic murmur
loudest in upper chest = AStenosis/Sclerosis
(only) Heard at Apex = Mitral regurgitation
between heart sounds 1 and 2
AF - more likely to be mitral
tip: feel the subclavian artery above the clavicle
Aortic stenosis
radiates to carotids
slow rising
narrow pulse pressure
heaving apex beat - hypertrophied heart due to extra work
absent 2nd Heart sound
sclerosis is slight calcification
AS presentation
examined CV system
describe pulse - regular, slow rising pulse - haemodynamic effect
Apex beat - not displaced and normal character - no LVH
heart sounds - normal and had ESM murmur, intensity 3/6, loudest in the 2nd intercostal space on the right radiates to carotids - aortic flow murmur, loud but no thrill, no sclerosis
no features of cardiac failure - so signs consistent with aortic stenosis - good negative
history to assess symptoms of As and request echo to look for aortic pressure gradient - assess indications for surgery
Other differentials: ASD and pulmonary stenosis
Sclerosis
does not radiate
assess AS and CXR - systolic murmur, early aortic stenosis
Causes of aortic stenosis
calcific degeneration
biscuspid valve - turners
Symptoms of AS
Syncope
Angina
Left-Ventricular Failure
Sudden Death
ASH - Angina, Syncope, Heart failure
Signs of severity of Aortic stenosis
Narrow pulse pressure / slow rising pulse – much harder to pump
delayed closure of A2 or reveresed splitting
absent 2nd HS
heaving apex beat
features of CCF
symptomatic
Indications for surgery in AS
symptomatic
asymptomatic + LVEF < 50%
Mean transcalcular pressure gradient > 40mmHg, valve area <1cm2 or jet velocity > 5m/s
Concomitant CABG
Grading of murmurs
1 - audibe to expert
- just audible to non-expert
- clearly audible
- clearly audible with palpable thrill
- audible with stehoscope only lightly applied
- audible without stehoscope on chest
Valve replacement work through
Sternotomy scar - valve replacement - warfarin / heart sounds
CABG - Saphenous scar, tar staining, xanthelasma
assess AF and CCF as well
Sternotomy scar with warfarin
metallic valve - click, heart sounds, murmur, pulse regularity
Present metallic valve
midline sternotomy scar and there was warfarin at the bed side
metallic click heard with first heart sound and second heart sound was normal
mitral = first heart
aortic = second heart sound
look for AF
Tissue valve presentation
no audible sounds with a mid-line sternotomy scar
No scars on legs
No warfarin on the bedside
could also be Prevsious CABG using internal thoracic artery. or repair of congential cardiac disease
Severe anaemia
cause of high output heart failure
