Flashcards in Hogan 1-on-1 Tut #1 Deck (16):
1

what is transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI)?

similar to a stent placed in an artery, the TAVI approach delivers a fully collapsible replacement valve to the valve site through a catheter

2

Pulseless electrical activity (PEA) aka?

electromechanical dissociation (EMD)

3

what is Pulseless electrical activity?

unresponsiveness and lack of palpable pulse in the presence of organized cardiac electrical activity. PEA does not mean mechanical quiescence.

4

electromechanical dissociation (EMD) aka PEA is what?

-cardiac contractions are absent in the presence of coordinated electrical activity.
-the absence of peripheral pulses should not be equated with PEA, as it may be due to severe peripheral vascular disease.

5

What is dobutamine?

sympathomimetic: it's an Inotropic agent; vasodilator. mimics the agonistic actions of noradrenaline or adrenaline on the alpha and/or beta adrenoreceptors.

6

dobutamine used when?

Inotropic support in acute heart failure, cardiogenic and septic shock

7

What does Noradrenaline do?

it's a Sympathomimetic: Vasoconstrictor with few cardiac effects.

8

indications for Noradrenaline?

Acute hypotension

9

IgA Nephropathy presents?

normal serology
IgA in the mesangium

10

Post-Strep Glomerulonephritis classically presents with?

hypocomplementemia: immune complexes

11

timing of IgA Nephropathy versus Post-Strep Glomerulonephritis?

PSGN is 2 weeks after an infection
IgA Nephro has have pharyngitis and nephritis at the same time

12

What is ASOT?

Antistreptolysin O Test to detect: group A, C and G streptococci,

13

ASOT to help detect what 4 things?

rheumatic fever
post streptococcal glomerulonephritis
scarlet fever
erysipelas

14

what is Marantic endocarditis aka?

Noninfective Endocarditis

15

what causes noninfective endocarditis?

sterile platelet and fibrin thrombi on cardiac valves and adjacent endocardium in response to trauma, circulating immune complexes, vasculitis, or a hypercoagulable state

16

Marantic endocarditis in what conditions? what happens?

chronic wasting diseases
thrombotic vegetations tend to form on congenitally abnormal cardiac valves or those damaged by rheumatic fever.
