Coronary Angioplasty, also called Percutaneous Coronary Intervention (PCI), is a procedure by which blockage in the coronary artery is opened using a dilatation balloon catheter, followed by a deployment of an expandable stent. It is performed to remodel a diseased blood vessel in order to increase perfusion or revascularize a cardiac muscle.
The patient will undergo an imaging diagnostic procedure called a coronary angiogram to see if the blockages can be intervened with angioplasty.
If the interventionist finds significant narrowing of the vessels during coronary angiogram, the physician may proceed to angioplasty and stenting immediately after the angiogram or can be scheduled another day if patient’s condition still warrants it and upon patient’s request.
A small mesh wire tube called stent is placed inside a blocked artery and stays there permanently to open the narrowed artery or arteries to prevent further narrowing. A single stent or multiple stents in a single blocked artery can be used. In some cases, multiple blocked arteries can also be revascularized by placement of multiple stents. When clogged arteries cannot be opened using stents the patient is advised to undergo Coronary Artery Bypass Graft.
Deployment of stents is usually done via flouroscopy guidance and with the use of contrast media to help visualize proper placement. Access can be radial or femoral approach. Repeat angiogram is done after the stent was deployed to check if the blocked artery was already dilated and blood flow is restored up to the distal part of the artery. Patient is usually transferred at the Coronary Care Unit (CCU) after the procedure for monitoring. Maintenance medications are usually prescribed together with lifestyle modification.
For scheduled cases:
The patient will be admitted at the hospital the night before the procedure.
An informed consent will be secured from the patient
The doctor will instruct the patient not to eat or drink (NPO- nothing per orem) anything for 4 hours before the procedure.
The doctor will assess the patient’s physical and medical history and will review diagnostic tests done such as Coronary Angiogram, ECG, 2D Echo. Patient’s creatinine is usually checked prior to procedure as basis for contrast media to be used. History of allergies on food especially seafood and on drugs will be noted.
The patient’s groin will be shaved prior to the procedure as another possible access in case radial approach is not feasible or unsuccessful.
An intravenous line will be initiated, preferably on left hand, once admitted or once patient is put on NPO (nothing per orem) especially for diabetic patient.
Certain medication such as Metformin will be put on hold 1-2 days prior to procedure.
Anticoagulant medications such as Aspirin as also given upon admission or few hours prior to procedure.
Medications for mild sedation are usually given at least 30 minutes prior to procedure.
Patient may resume diet once fully awake if patient is stable.
