18 organisms.
One method.
You are not revising all of microbiology today. You are revising the 18 organisms that belong to cardiovascular — the exact list is below — and you are doing each one the same way. That method is WRWRT.
Opening the SystemWise Micro chart and scanning the whole image is how an hour disappears without a single organism being revised. The list has already been made for you. Work down it, apply WRWRT to each one, and stop when it ends.
If you have only ever used First Aid, you can revise every organism on this page from First Aid and the FA Guide alone. The list below is still your list; only the source changes. You will not fail for skipping Sketchy.
But if you have the time, invest in Sketchy — or whichever video resource is named against each organism. The whole point of a named resource is that somebody already worked out which one teaches that organism best, so you do not spend an evening sampling three of them. Sketchy is a memory palace; First Aid is a reference. If you can afford the hours, use both.
PART ONEThe WRWRT method
Five steps, in order, for every organism. The order is the whole point: each step only works because of the one before it.
Watch
1x speed. Full attention. No notes. Notes split your attention, and your brain cannot process the visual story and write at the same time. Just watch.
Recall
Close the video. Look away from the screen. Walk the whole story through chronologically, in your head — start to finish, in order.
Watch again
1.5x or 1.75x, and only the parts you could not recall — not the whole video again. Fill the gaps, then move on.
Read the PDF
Open the Sketchy Micro PDF for those organisms — the written version of what you just watched. Read it once.
Test
Finish with the FA Guide MCQs for those exact organisms, in the Microbiology section — not the whole of Micro, just what you covered.
The goal is not to master cardiovascular microbiology today. It is to finish these 18 and move on. The real learning happens when you meet these organisms in UWorld weeks from now and the visual story comes straight back.
PART TWOThe 18 cardiovascular organisms
This is the entire cardiovascular column of the SystemWise Micro chart. Nothing else from Micro belongs to this system, and nothing here belongs to another one.
- 01Staphylococcus aureus — acute, IV drug use, tricuspid
- 02Viridans group streptococci — subacute, after dental work
- 03Staphylococcus epidermidis — prosthetic valves
- 04Enterococcus — after GI/GU procedures
- 05Streptococcus gallolyticus — look for colon cancer
- 06Streptococcus pyogenes — Group A, rheumatic fever
- 07Corynebacterium diphtheriae — diphtheritic myocarditis
- 08Borrelia burgdorferi — Lyme carditis, AV block
- 09Treponema pallidum — syphilitic aortitis
- 10Coxsackievirus B — commonest viral myocarditis
- 11Echovirus — myocarditis, pericarditis
- 12Adenovirus — myocarditis in children
- 13Parvovirus B19 — myocarditis
- 14HIV — dilated cardiomyopathy
- 15Trypanosoma cruzi — Chagas: dilated cardiomyopathy, megacolon
- 16Taenia solium — cysticercosis, rarely myocardium
- 17Candida
- 18Aspergillus
TB, COVID, HIV and the Bunyaviruses are done directly from First Aid, not from Sketchy. Skip them in Sketchy entirely.
PART THREEOne organism, worked through
Here is WRWRT applied to the first organism on the list, in full, so you know exactly what each step looks like before you do it 17 more times.
Watch the Staphylococcus aureus sketch, once, at 1x
Phone away. Nothing in your hands. You are watching a story, and you will be asked to retell it in about four minutes.
Close it and retell the story out loud
Not a fact list — the sketch, in the order it happened. Then check yourself against the prompts below. If you cannot answer one, that is a gap, not a failure.
Rewatch only the gaps
Whatever did not come back, scrub to that part of the sketch. 1.75x. Ninety seconds, not nine minutes. Then stop.
Read the Staphylococcus aureus pages of the Sketchy Micro PDF
Once, properly. Highlight only what you failed to recall a moment ago — those highlights are a precise map of where your memory breaks, and they are what you revisit before the exam. Everything else you already have.
Do the FA Guide MCQs for Staphylococcus aureus
Microbiology section, this organism only. Getting one wrong here costs you two minutes and fixes the gap permanently; the same gap found on test day costs you the mark.
That is one organism. Do the same for Viridans group streptococci, Staphylococcus epidermidis, Enterococcus, Streptococcus gallolyticus, Streptococcus pyogenes, Corynebacterium diphtheriae, Borrelia burgdorferi, Treponema pallidum, Coxsackievirus B, Echovirus, Adenovirus, Parvovirus B19, HIV, Trypanosoma cruzi, Taenia solium, Candida and Aspergillus — and cardiovascular micro is finished. Do not go back to the chart. Do not start another system's organisms. Close this and move to your cardiovascular First Aid reading.
