PCI

Who first introduced percutaneous transluminal coronary angioplasty (PTCA) as an alternative to coronary bypass surgery?

• Charles Dotter

• Andreas Gruentzig

• David P. Faxon

• Deepak L. Bhatt

What is the main advantage of drug-eluting stents introduced in 2003 for coronary interventions?

• They are less expensive

• They release antiproliferative drugs to reduce restenosis

• They are easier to implant

• They do not require anticoagulation

Which artery access sites are commonly used for percutaneous coronary interventions?

• Femoral or carotid artery

• Radial or femoral artery

• Brachial or aortic artery

• Subclavian or iliac artery

What is the primary function of a stent in coronary angioplasty?

• To dissolve blood clots

• To act as a scaffold and prevent vessel recoil

• To deliver medication directly to the heart muscle

• To measure blood pressure in the artery

Which of the following medications may be given to patients to prevent thrombotic complications during percutaneous coronary intervention?

• Aspirin and platelet P2Y12 inhibitors

• Beta-blockers and statins

• Calcium channel blockers and nitrates

• Diuretics and ACE inhibitors

Why did the introduction of coronary stents in 1994 represent a major advance in percutaneous coronary intervention?

• They made the procedure faster

• They reduced acute complications and late restenosis

• They eliminated the need for anesthesia

• They allowed for non-invasive procedures

What is the main reason percutaneous coronary intervention (PCI) is performed more than twice as often as coronary artery bypass surgery in the United States?

• PCI is less expensive

• PCI is less invasive and requires shorter hospitalization

• PCI is more effective for all patients

• PCI does not require any medication

Which of the following is a primary purpose of drug-coated balloons in coronary interventions?

• To prevent restenosis after stent placement

• To dissolve blood clots in peripheral arteries

• To increase the flexibility of the vessel wall

• To measure blood pressure within the artery

What is the main advantage of rotational atherectomy in the treatment of coronary artery disease?

• It is used to aspirate thrombus in acute STEMI

• It is particularly useful in heavily calcified plaques that are resistant to balloon dilatation

• It is the preferred method for treating soft plaques

• It is used to deliver drug-eluting stents

According to the text, what is the approximate percentage of angioplasty procedures in which stents are currently used?

• 50%

• 70%

• 90%

• 100%
