Cath Lab Terms

Front 1

Angiography

Back 1

Examination of blood vessels via radiation after injection of contrast

Front 2

Angioplasty

Back 2

A procedure that uses a balloon to open blocked artery

Front 3

Atherectomy

Back 3

Procedure where plaque is removed from artery

Front 4

Blow back

Back 4

Flow of contrast back into aorta when injecting contrast

Front 5

Cardiac index

Back 5

Cardiac output divided by BSA. Shows cardiac output compared to body size

Front 6

Damping

Back 6

Fall in pressure due to restriction of flow. Usually wedged in stenosis

Front 7

Fick cardiac output

Back 7

Volume of blood ejected by the heart perminute. Calculated BSA, HR, blood saturation, O2 consumption

Front 8

Hypertrophic Obstructive cardiomyopathy

Back 8

Narrowing that occurs below the aortic valve. Gradient is within the LV due to stenosis

Front 9

IVUS intra vascular ultrasound

Back 9

View of vessel via ultrasound inside artery

Front 10

LVEDP

Back 10

Measurement reflects the pressure in the heart and lungs while heart is at rest

Front 11

PCI Percutaneus coronary interventio

Back 11

Includes angioplasty stenting and atherectomies

Front 12

PCW Pulmary Cap Wedge

Back 12

Pressure measurement that refelects LA pressure

Front 13

PDA

Back 13

Usually originates from RCA or Cx. When it comes from RCA its considered right dominate and visa versa

Front 14

Pulse pressure

Back 14

Systolic minus diastolic

Front 15

Reperfusion beats

Back 15

PVCs or other ectopy noted after opening blockage. This is due to the heart receving blood after period of ischemia

Front 16

Thermos

Back 16

Volume of blood ejected by heart per min. CO cooler than body temp injected into Ra via swans ganz temp change in the PA is recorded. Measures liters per min.

Front 17

Antegrade flow

Back 17

In direction of blood flow

Front 18

Elasric recoila

Back 18

scenario where the artery renarrows after dilating it with a ballon

Front 19

Guide wire

Back 19

Thin wire used for pci

Front 20

Ostial leison

Back 20

A blockage that involves the very beginning or opening of the artery

Front 21

ACT

Back 21

Active Clotting Time
