| Question | Answer |
|---|---|
| Aneurysm | An aneurysm is a localized dilation of an artery that most commonly involves the aorta, especially its abdominal portion. |
| Angiography | Angiography is a general term that describes the radiologic examination of vascular structures within the body after the introduction of an iodinated contrast media or gas. |
| Arteriography | Visceral and peripheral angiography procedures can be categorized generally as either arteriography or venography. — OR — Radiologic examination of arteries after injection of a radiopaque contrast medium. |
| Arteriosclerotic | Indicative of a general pathologic condition characterized by thickening and hardening of arterial walls, leading to general loss of elasticity. |
| Arteriotomy | Surgical opening of an artery. |
| Atherectomy | Excision of atherosclerotic plaque. |
| Biliary Stent | Wire mesh or plastic conduit placed to maintain flow. |
| CIT tech (cardiovascular and interventional technologist) | Technologists specializing in angiographic and interventional procedures. |
| Claudication | Cramping of the leg muscles after physical exertion because of chronically inadequate blood supply. |
| Endarterectomy | Surgical operation to “clean out” artery (plaque) and restore normal bloodflow. |
| Embolization | Transcatheter embolization involves the therapeutic introduction of various substances to occlude or drastically reduce blood flow within a vessel |
| Embolus | Foreign material, often thrombus, that detaches and moves freely in the bloodstream. - STOPS BlOOD FLOW - |
| French size | Measurement of catheter sizes; 1 French = 0.33 mm; abbreviated Fr. |
| Gastrostomy | tubes through an opening (ostomy) into the stomach (gastro) to supplement nutrition. For long term feeding |
| Gianturco wool coil (embolizer) | stops bloodflow |
| Guidewire | Tightly wound metallic wire over which angiographic catheters are placed. |
| Hematoma | Collection of extravasated blood in an organ or a tissue space. |
| Intervention | Therapeutic modality—mechanical or pharmacologic—used to modify the course of a disease process. |
| Ischemic | Indicative of a local decrease of blood supply to myocardial tissue associated with temporary obstruction of a coronary vessel, typically as a result of thrombus (blood clot). |
| IVC filter | Filters that are designed as a conical shape to trap clots in the central lumen. They are also designed to be placed in vena cavae ranging up to 20 to 30 mm in diameter. |
| Occlusion | Obstruction or closure of a vessel, such as a coronary vessel, as a result of foreign material, thrombus, or spasm. |
| Patency | State of being open or unobstructed. |
| Percutenous transluminal angioplasty (PTA) | Surgical correction of a vessel from within the vessel using catheter technology. |
| Percutaneous transluminal coronary rotational atherectomy (PTCRA) | Manipulative interventional procedure involving a device called a Rotablator to remove atherosclerotic plaque from within the coronary artery using a high-speed rotational burr. |
| Repurfusion | Reestablishment of blood flow to the heart muscle through a previously occluded artery. |
| Restenosis | Narrowing or constriction of a vessel, orifice, or other type of passageway after interventional correction of primary condition. |
| Stent | Wire mesh or plastic conduit placed to maintain flow. |
| Thrombolytic | Capable of causing the breakup of a thrombus. |
| Thrombosis | Formation or existence of a blood clot. |

| Cardiolite--- | myocardial perfusion ( blood flow) |
| Thallium -- | myocardial imaging |
| Xenon gas- | lung ventilation |
| Hot vs cold spot? | HOT: more metabolic activity. COLD: less metabolic activity |
