Eponyms and History Flashcards
Eponym for parchment paper right heart
Uhl’s anomaly
(nonfunctioning fibroelastic tissue replaces the RV myocardial layer)
Borders of Koch’s triangle
Coronary sinus
Tendon of Todaro
TV septal leaflet
(AV node lies within)
What is an Austin Flint murmur
apical diastolic murmur due to AI jet restricting opening of the anterior mitral leaflet
What is Kussmaul’s sign
Increased JVP with inspiration
Eponym and mechanism for post-PVC drop in aortic pulse pressure + increase in peak LV systolic pressure
Brockenborough-Braunwald-Morrow sign
Post-PVC compensatory pause –> increased calcium release –> increased contractility –> increased LV SP and LVOT gradient
What is the Bowditch effect?
Higher HR –> increased contractility
(has to do with increase calcium release)
(ie, +chronotropy increases CO by more than just simple CO=HRxSV)
