Edith louise potter 1901 1993 was an american pediatric pathologist.
Life in the fast lane rv infarct.
Inferior st elevation myocardial infarction.
Patients with rv infarction are very preload sensitive due to poor rv contractility and can develop severe hypotension in response to nitrates or other preload reducing agents.
Right ventricular infarction complicates up to 40 of inferior stemis.
Chris is an intensivist and ecmo specialist at the alfred icu in melbourne.
And the potter classification of polycystic kidney disease 1964.
Along with posterior mi you may want to look at rv infarction when you see an inferior mi.
A case report in 1974 was the first to mention right ventricle rv infarction as a distinct entity noting that patients with this pathology exhibit a unique clinical and haemodynamic syndrome.
It commonly shows on a 12 lead ecg as st segment elevation in v1 and in leads ii and iii with iii showing greater than ii as lead iii has a better angle on the rv litfl 1.
Posterior extension of an inferior or lateral infarct implies a much larger area of myocardial damage with an increased risk of left ventricular dysfunction and death.
He is also the innovation lead for the australian centre for health innovation at alfred health and clinical adjunct associate professor at monash university.
Isolated posterior mi is less common 3 11 of infarcts.
Posterior infarction accompanies 15 20 of stemis usually occurring in the context of an inferior or lateral infarction.
This is because the resulting weakness of the rv makes the patient s cardiac output extremely preload sensitive.
They often present in shock and.
Clinical significance of rv infarction.
They typically do not occur in isolation due to improved collateral blood supply of the right ventricle and overall smaller mass of this chamber.
Patients with rv infarction are very preload sensitive due to poor rv contractility and can develop severe hypotension in response to nitrates or other preload reducing agents.
Hypotension in right ventricular infarction is treated with fluid loading and nitrates are contraindicated.
Life in the fast lane.
Generally have a more favourable prognosis than anterior myocardial infarction in hospital mortality only 2 9 however certain factors indicate a worse outcome.
Syncope shock and chest pain.
An infarction of the right ventricle.
Lmca left main coronary artery occlusion st elevation in avr.
Right ventricular infarctions are noted to occur with as many as 40 of inferior ami.
