Objective:
Percutaneous coronary intervention for coronary bifurcation lesion is very challenging, especially for true bifurcation lesions. Although the jailed semi-inflated balloon technique is one of the established methods for treatment of coronary bifurcation lesions, little is known regarding the configuration of the side branch orifice after stent implantation using this technique.
Methods:
We report a 73-year-old male patient with angina pectoris who was successfully treated with percutaneous coronary stent implantation for a true bifurcation lesion of the right coronary artery with an obtuse angle using the jailed semi-inflated balloon technique.
Results:
Three-dimensional optical frequency domain imaging clearly showed that there were no signs of plaque or carina shift into the side branch after stent implantation using this technique.
Conclusions:
This case report highlights that the jailed semi-inflated balloon technique is a safe and useful treatment for coronary true bifurcation lesions with an obtuse angle.
