Abstract
Background: Coronary bifurcation lesions represent one of the most technically complicated subsets of percutaneous coronary intervention (PCI) and are linked to increased restenosis and adverse cardiac events. The modified jailed balloon technique (M-JBT) was developed to protect the side branch while maximizing expansion of the main vessel stent.
Purpose: To assess the effectiveness and operational outcomes of the modified jailed balloon technique in managing coronary bifurcation lesions in patients undergoing PCI at a tertiary cardiac care centre.
Methods: A prospective observational study was conducted at AFIC/NIHD between September 2023 and February 2024, enrolling 100 patients with coronary bifurcation lesions undergoing PCI. Patients underwent PCI using M-JBT where a side-branch non-compliant balloon was placed and jailed uninflated during main vessel stenting, followed by optional side branch optimization. Procedural success, residual stenosis, side branch flow, and in-hospital complications were evaluated via quantitative coronary angiography and analyzed using SPSS version 26.
Results: Procedural success was achieved in 96% of cases. Post-stenting mean residual stenosis was $6.8 \pm 2.4\%$ in the main vessel and $14.5 \pm 3.7\%$ in the side branch. TIMI-3 flow was preserved in both branches in 93% of patients. Minor dissections occurred in 4% of cases, and side branch occlusion was seen in 3%. In-hospital MACE occurred in 2% of cases, and 6-month MACE was 4%.Conclusion: The modified jailed balloon technique is a safe, effective, and technically feasible approach for treating coronary bifurcation lesions. It provides high procedural success, maintains side branch patency, and minimizes complications.
