Summary
Kissing balloon technique can cause coronary perforation, a rare PCI complication. Considering proximal lumen shape, not just balloon size and pressure, is crucial for left main trunk interventions.
Area of Science:
- Interventional Cardiology
- Cardiovascular Research
Background:
- Percutaneous coronary intervention (PCI) is a common procedure for coronary artery disease.
- Coronary perforation is a rare but potentially life-threatening complication of PCI.
Observation:
- The kissing balloon technique, used to optimize results in complex coronary lesions, can lead to coronary perforation.
- In this case, perforation occurred despite careful attention to balloon diameter and inflation pressure.
Findings:
- The proximal lumen's elliptical, rather than circular, shape was a critical factor contributing to the perforation during kissing balloon deployment.
- Successful hemostasis was achieved using a 90-second perfusion balloon inflation.
Implications:
- Balloon form, specifically the proximal lumen's geometry, should be considered a vital safety factor in the kissing balloon technique, particularly for left main trunk interventions.
- This finding highlights the need for enhanced pre-procedural assessment and technique modification to mitigate perforation risks.
