This chapter covers percutaneous coronary intervention. It starts with the history of the procedure, indications, and techniques for imaging the lesion, and describes different systems of lesion classification. The equipment required for percutaneous coronary intervention, including guiding catheters, angioplasty guide wires, angioplasty balloons, and intracoronary stents (drug-eluting stents, bioabsorbable scaffolds, etc.) are all covered. The percutaneous coronary intervention procedure is then explained. Intravascular ultrasound is compared and contrasted to optical coherence tomography. Antiplatelet and anticoagulant therapies are described in detail, and finally specific techniques in complex PCI are covered.

Cardiac comorbidities are oftentimes not limited to a single diagnosis, and multiple cardiac abnormalities may have to be considered when administering an appropriate anesthetic. Atrial fibrillation is an abnormal cardiac rhythm with uncoordinated depolarization of the atria causing an irregularly irregular ventricular response. Optimization requires heart rate control as well as anticoagulation, which must be considered prior to any surgical procedure. Percutaneous coronary intervention or coronary stents are placed in the coronary arteries in the face of coronary artery stenosis. The circumstances of when the stents were placed, as well as the type of stents that were used, will determine how long dual antiplatelet therapy must be undertaken and when elective surgery can take place.
