Definition and Incidence
Coronary perforations are uncommon (< 1%) complications of percutaneous coronary intervention (PCI) and are associated with significant morbidity and mortality rates. [1] [2] [3] [4] [5] Coronary perforations are infrequent in patients undergoing balloon angioplasty (0.1%) compared with patients undergoing atheroablative therapy (1.3%; P< 0.001) [6] [7] Perforation due to coronary guidewires may present late after the procedure.
Risk Factors
The use of hydrophilic wires and wires in which the court extends to the tip are wire characteristics associated with perforation. Lesions with the highest risk of perforation include chronic total occlusions.
Diagnosis
Perforation is an angiographic diagnosis. It appears as a small extraluminal extravasation of blush in the distribution of the target vessel. Care should be taken to routinely visualize the distal extent of the vessel following PCI to exclude the presence of a wire perforation. Emergency echocardiography should be performed to rule out the presence of a pericardial effusion or pericardial tamponade.
Prognosis
The prognosis following coronary perforation depends on the extent of extravastion into the pericardium [8].
Classification
The following classification scheme has been developed based on angiographic appearance of the perforation:
- Type I perforations including an extraluminal crater without extravasation
- Type II perforations containing pericardial or myocardial blushing
- Type III perforations having a ≥ 1 mm diameter with contrast streaming; and cavity spilling [9].
Coronary Artery Perforation

- Class I perforations were associated with no deaths and cardiac tamponade in 8% of patients.
- Class II perforations were associated with no deaths and cardiac tamponade in 13% of cases
- Class III perforations were associated with death in 19% and cardiac tamponade in 63% of patients [10].
Management of Vessel Perforation
Initial management strategies include:
- Prolonged balloon inflation: For this reason it is often wise for a cardiac catheterization laboratory to have perfusion balloons in a range of sizes available.
- Reversal of anticoagulation: This would included administration of protamine to reverse heparin and administration of platelets if abciximab has been administered.
- In refractory cases, polytetrafluoroethylene covered stents (stent grafts) can be used to seal the perforation [11] [12] .
- The administration of platelets can be considered to reverse the effects of antiplatelet agents.
- The administration of protamine can be considered to reverse the effects of unfractionated heparin. Protamine will also partially reverse the antithrombotic effect of enoxaparin if this antithrombin was used.
- Other techniques include coil embolization, the injection of clotted blood, the use of gel foam and the injection of thrombin at the site of the perforation.
Approximately one third of cases of PCI-associated coronary artery perforation require emergent cardiac surgery.
