A Case of Balloon Rupture Cause Serious Complication during Percutaneous Coronary Intervention

Balloon rupture in the process of percutaneous coronary intervention (PCI) leading to coronary artery dissection, subintimal hematoma and hematoma extension after stent implantation is an uncommon complication, but it has important clinical significance. The reason for balloon rupture during PCI and hematoma extension after stent implantation is not clear. In this case, Balloon rupture may be due to excessive balloon dilation pressure, severe coronary artery calcification, balloon dilatation with gas presence and poor quality of the balloon; hematoma extension after stent implantation may be for remaining undiscovered hematoma and dissection. We should pay attention to these risk factors and prevent the occurrence of clinical complications in the treatment of PCI.
