What does PTCA stand for?

Percutaneous Transluminal Coronary Angioplasty or PTCA is a procedure used in the treatment of ischemic heart diseases that are due to the blockages in the coronary circulation. It can be defined as the process of dilating a coronary artery stenosis using an inflatable balloon and a metallic stent introduced into...

Who is not a good candidate for PTCA?

Patients with left main coronary heart disease are poor candidates for the PTCA procedure due to the risk of acute obstruction or spasm of the left main coronary artery during the procedure. It is also not recommended for patients with hemodynamically insignificant (less than 70%) stenosis of the coronary arteries.

What is the difference between CABG and PTCA?

In comparison to coronary artery bypass grafting (CABG), PTCA is associated with lower morbidity and mortality, shorter convalescence and lower cost 3). It can significantly improve blood flow through the coronary arteries in about 90% of patients with relief of anginal symptoms and improvement in exercise capacity.

What is the mortality and morbidity associated with PTCA?

PTCA is widely practiced and has risks, but major procedural complications are rare. The mortality rate during angioplasty is 1.2% 13). People older than the age of 65, with kidney disease or diabetes, women and those with massive heart disease are at a higher risk for complications.

What is a PTCA?

Percutaneous Transluminal Coronary Angioplasty (PTCA) and Percutaneous Coronary Intervention (PCI) both essentially mean the process of dilating a coronary artery stenosis using an inflatable balloon and a metallic stent introduced into the arterial circulation via the femoral, radial or the brachial artery. Nowadays it is the most commonly used intervention in the treatment of ischemic heart diseases. It should be stressed that there is no difference between PTCA and PCI. They are in fact synonyms. However, here, we will discuss PTCA or PCI procedure and complications in detail.

What is PTCA in a stent?

PTCA or Percutaneous Transluminal Coronary Angioplasty is the process of dilating a coronary artery stenosis using an inflatable balloon and a metallic stent introduced into the arterial circulation via the femoral, radial or the brachial artery. Percutaneous Coronary Intervention is another name given to this procedure. Therefore, there is no difference between PTCA and PCI.

Is PTCA recommended for calcified arteries?

There is a better prognosis in the presence of a soft lesion that does not involve any arterial bifurcations. PTCA is not recommended when the site of obstruction is within a calcified, long and tortuous artery which is bifurcating at an adjacent point.

Is PTCA the same as PCI?

There’s no difference between PTCA and PCI since Percutaneous Transluminal Coronary Angioplasty, or PTCA is also referred by the name Percutaneous Coronary Intervention or PCI.

It is also not recommended for patients with hemodynamically insignificant (less than 70%) stenosis of the coronary arteries.

What is PTCA surgery?

PTCA is performed under local anesthesia and serves as an alternative to coronary artery bypass surgery (CABG).

How long does a PTCA procedure last?

During the procedure, anticoagulation is administered to prevent the formation of clots. Most coronary angioplasty procedures last between 30 minutes to 3 hours depending upon the technical difficulties of the case.

What test is used to determine if a blockage is a PTCA?

How you prepare. Before a scheduled PTCA procedure, your doctor will review your medical history and do a physical exam. You’ll also have an imaging test called a coronary angiogram to see if your blockages can be treated with angioplasty.

Is PTCA a risk?

PTCA risks. Although percuta neous coronary angioplasty is a less invasive way to open clogged arteries than bypass surgery is, the procedure still carries some risks. The most common percutaneous coronary angioplasty risks include: Re-narrowing of your artery (restenosis).

Is PTCA better than CABG?

In comparison to coronary artery bypass grafting (CABG), PTCA is associated with lower morbidity and mortality, shorter convalescence and lower cost 3). It can significantly improve blood flow through the coronary arteries in about 90% of patients with relief of anginal symptoms and improvement in exercise capacity.

The cardiologist controls the direction and movement of the PTCA guide wire, and balloon wire by twisting the part of guide wires that sit outside the patient. The balloon is then inflated and deflated repeatedly until the artery is patent. In most instances, a stent is required.

What is the RCA branch?

The right coronary artery (RCA) divides into the right posterior descending (PDA) and a (PL) posterolateral branch. RCA supplies blood to the ventricles, right atrium and sinoatrial node. Coronary arteries are end-arteries supplying the myocardium and blockage can lead to serious adverse effects.
