OBJECTIVE Many interventional cardiologists are concerned about the risk of side branch (SB) loss during main vessel (MV) stenting in complex bifurcation lesions. Therefore, novel techniques are required to reduce the risk of SB occlusion. Jailed semi-inflated balloon technique (JSBT) is one of the techniques developed for this. In this article we describe our clinical experience in SB patency assessment using a JSBT.
METHODS At our institution, 64 patients with 82 distinct coronary bifurcation lesions underwent percutaneous coronary intervention (PCI) via JSBT. In the majority of patients, the SB balloon was inflated with a higher pressure (4.8±2.0 atm) as distinct from JSBT. Procedural and immediate clinical outcomes were reviewed via baseline and post-procedural quantitative coronary angiography analysis.
RESULTS The majority of the patients had acute coronary syndrome (60.9%) and almost one third of the patients were Medina class 1.1.1. (32.8%). The jailed-balloon or wire was not entrapped during any PCI. SB ostial dissection was seen in only two patients. The minimal lumen diameter was improved in the MV and SB following PCI. There were no adverse cardiac events during in-hospital stays and at one month follow-ups.
CONCLUSIONS JSBT provides maximum SB protection with bifurcation lesions and requires less time than a complex technique. There was no significant SB occlusion risk even though the SB balloon was inflated with a slightly higher pressure. The immediate clinical outcomes and procedural success of this study can encourage interventional cardiologists to use this technique safely with reliable preservation of SB patency.
