Coronary Arteries
This coronary artery is known as the “widowmaker” because blockage is often fatal.
What is the LAD?
STEMI occurs due to this event involving plaque
What is plaque rupture?
PCI is used to restore this to coronary arteries.
What is blood flow?
A patient with femoral access and no closure device must remain flat for this long
What is 6 hours?
This bracelet‑like device provides hemostasis after radial artery access.
What is a TR band?
These branches come off the Circumflex artery
What are the obtuse marginal (OM) branches?
This segment elevation on an EKG indicates full-thickness myocardial injury
What is ST elevation?
This device is placed after angioplasty to keep the vessel open.
What is a stent?
Pain in the flank, back, or lower abdomen may indicate this dangerous bleeding complication.
What is retroperitoneal hemorrhage?
Air is removed in this increment during radial band weaning
What is 1–2 mL every 10 minutes?
The PDA branches off this artery
What is the RCA?
NSTEMI often shows this pattern on the ST segment
What is ST depression (or transient elevation or T‑wave inversion)?
Stents can be drug-eluting or this type
What is bare metal?
When holding pressure for groin bleeding, pressure should be applied here relative to the puncture site.
What is 1.5–2 cm proximal?
After the radial band is removed, this colored band must be applied for 24 hours.
What is the blue band?
This major coronary artery sits at the top of the heart and divides into LAD and Circumflex
What is the left main?
This blood test detects cardiac-specific proteins released when heart muscle is injured
What is troponin?
This type of PCI approach treats one vessel first, then returns later for others
What is staged stenting?
A fem-stop is indicated if bleeding continues or reoccurs after this amount of manual pressure time.
What is 30 minutes?
Radial band weaning begins sooner when ACT is below this value.
What is 250?
These branches come off the LAD
What are the diagonal and ramus branches?
A high-sensitivity troponin <14 ng/L is considered this
What is normal?
Before cath, patients must be NPO except for these meds.
What are cardiac meds (ASA/antiplatelets)?
Radial band weaning begins sooner when ACT is below this value.
What is 250?
One reason to call the cath lab during radial weaning is the loss of this
What is a palpable pulse?
