What is a common immediate therapeutic maneuver to control ongoing coronary perforation during PCI?

• A. Balloon tamponade to control bleeding at perforation site during PCI.
• B. Increase contrast volume to identify the leak.
• C. Switch to MRI to monitor.
• D. Ligation.

Answer: (C)

The immediate concept is to physically control the leak at the perforation site by inflating a balloon over it. Balloon tamponade mechanically compresses the vessel wall, reducing or stopping the bleed into the pericardial space and buying time to implement definitive treatment. This is the fastest, most practical percutaneous maneuver you can perform right away in the cath lab when a coronary perforation occurs, helping to stabilize the patient and preserve distal blood flow. Increasing contrast would not help and can worsen the situation by increasing potential bleeding and nephrotoxicity. Switching to MRI isn’t feasible during PCI because MRI-compatible imaging in the cath lab is not available for this acute complication, and most interventional equipment and devices are not compatible with MRI. Ligation is a surgical approach and not an immediate percutaneous maneuver during an ongoing PCI.
