CVT 2420 INVASIVE EXAM 1 QUESTIONS AND ANSWERS
What is cardiac catheterization? - CORRECT ANSWER✅✅the insertion of small plastic tubes called
catheters into arteries & veins to the heart; used for diagnostic procedures and intervention
what is Claude Bernard known for? - CORRECT ANSWER✅✅first applying cardiac catheterization (in a
horse); obtained ventricular pressures
What is Werner Forssman known for? - CORRECT ANSWER✅✅theorizing it was possible to safely insert
a tube through a vein in the arm using a urethral catheter
What is Andre Cournand known for? - CORRECT ANSWER✅✅began using catheters to study human
circulation, pulmonary physiology, and to measure cardiac output
What is Zimmerman known for? - CORRECT ANSWER✅✅first to demonstrate retrograde technique by
passing catheter into LV
What is Sven Ivar Seldinger known for? - CORRECT ANSWER✅✅first percutaneous femoral artery
technique
What are Ross, Cope, and Brochenbrough known for? - CORRECT ANSWER✅✅transseptal cath
What is Mason Sones known for? - CORRECT ANSWER✅✅first selective coronary angiogram; father of
coronary arteriography; Sones Technique: 1 inch incision to antecubital space to isolate brachial artery
What are Charles Dotter and Melvin Judkins known for? - CORRECT ANSWER✅✅found that by inserting
a series of stiff dilators gradually increasing in diameter through diseased vessels, blood flow improved
What is Judkins most known for? - CORRECT ANSWER✅✅using Seldinger's technique and catheters
with performed curves to visualize coronary anatomy; finding appropriate shapes for catheters to reach
the ositum of coronary arteries
, What is Rene Favaloro known for? - CORRECT ANSWER✅✅conducting first modern saphenous vein
bypass graft at Cleveland Clinic
What are Swan and Ganz known for? - CORRECT ANSWER✅✅introducing a flow directed balloon-
tipped catheter for monitoring right heart pressures & thermodilution cardiac outputs
What is Andreas Gruentzig known for? - CORRECT ANSWER✅✅interventional cardiology; first PTCA
(percutaneous transluminal coronary angioplasty)
What is a drug-eluting stent? - CORRECT ANSWER✅✅stent coated with slow-release medicine to help
prevent blood clots from forming in stent
What is X-ray? - CORRECT ANSWER✅✅type of electromagnetic radiation that can pass through the
body to create images of its internal structures
What are X-rays used for? - CORRECT ANSWER✅✅medical imaging to diagnose and treat medical
conditions; therapeutic (cancer treatments)
What does PACS stand for? What is it for? - CORRECT ANSWER✅✅Picture Archiving and
Communication System; securely store and digitally transmit electronic images
What does Dicom stand for? What is it? - CORRECT ANSWER✅✅Digital Imaging and Communications in
Medicine; international standard for medical images and associated information
How are x-rays produced? - CORRECT ANSWER✅✅by the acceleration of electrons from the cathode to
the anode and the abrupt stop once they hit the target material (tungsten)
How are X-rays converted into the image we see on screen? - CORRECT ANSWER✅✅image
intensifier(II); converts invisible image into visible image
What is the first step within the image intensifier? - CORRECT ANSWER✅✅the input phosphor converts
the x-ray photons to light photon
