title: Guidewire-induced coronary artery perforation treated with transcatheter delivery of subcutaneous tissue.
abstract: In three cases of small coronary artery perforation by guidewires during percutaneous coronary intervention, coronary leakage continued despite prolonged balloon inflation and reversal of heparin. Subcutaneous tissue was selectively delivered to perforated vessels by means of microcatheters in a successful attempt to stop leakage. This method appears to be extremely effective for treating guidewire-induced perforations of distal coronary arteries.
