Balloon-stent kissing technique versus jailed wire technique for interventional treatment of coronary bifurcation lesions: Comparison of short- and long-term clinical outcomes.

ABSTRACT: Side-branch occlusion is a serious complication of provisional one-stent strategies used to treat coronary bifurcation lesions. The aim of the study was to compare the short- and long-term clinical outcomes between the balloon-stent kissing technique (BSKT) and jailed wire technique (JWT) in patients with non-left coronary bifurcation lesions.This prospective, double-blinded, randomized controlled study enrolled 89 consecutive patients (aged 18-85 years) with 90 true bifurcation lesions (hemadostenosis ?70%; bifurcation angle <90°; Medina classification 1.1.1, 1.0.1, or 0.1.1) who underwent percutaneous coronary intervention (PCI) at the Zhongshan Hospital Affiliated to Dalian University (China) between January 2013 and May 2016. The patients were randomly divided into the BSKT (44 patients, 45 lesions) and JWT (45 patients, 45 lesions) groups. The intervention was conducted according to technical requirements using a single-stent strategy. Operative success rate, occurrence of complications, postoperative quantitative coronary angiography, and incidence of perioperative and long-term major adverse cardiovascular events (MACEs) were compared between groups.The intervention success rate was 100% in both groups. After main-branch stenting, the BSKT was associated with significantly lower rates of side-branch occlusion (0% vs 15.6%, P?

Project description:BackgroundProvisional 1-stent technique is currently regarded as the default approach for the majority of bifurcation lesions. Nonetheless, 2-stent techniques may be required for complex bifurcations with high compromise risk or fatal consequences of side branch (SB) occlusion. Limitations exist in current approaches, as stents gap, multiple metal layers and stent malapposition caused by imprecise placement with fluoroscopic guide and intrinsic technical defects. This study was designed to investigate the effectiveness of the novel Szabo 2-stent technique for coronary bifurcation lesions.MethodsIn the Szabo 2-stent technique, one stent is precisely implanted at the SB ostium with Szabo technique resulting in a single strut protruding into the main vessel (MV). After MV rewiring and SB guidewire withdrawal, another stent is implanted in MV followed by proximal optimization technique, SB rewiring, and final kissing inflation (FKI).ResultsThe technique tested successfully in silicone tubes (n = 9) with: procedure duration, 31.2 ± 6.8 min; MV and SB rewiring time, 26.8 ± 11.2 s and 33.3 ± 15 s; easy FKI; and 2.3 ± 0.5 balloons/procedure. Bifurcation lesions (n = 22) were treated with angiographic success in MV and SB, respectively: increased minimal lumen diameter (0.63 ± 0.32 mm to 3.20 ± 0.35 mm; 0.49 ± 0.37 mm to 2.67 ± 0.25 mm); low residual stenosis (12.4 ± 2.4%; 12.4 ± 2.3%); and intravascular ultrasound confirmed (n = 19) full coverage; minimal overlap and malapposition; minimal lumen area (2.4 ± 1.2 mm2; 2.1 ± 1.0 mm2); plaque burden (78.1 ± 11.3%; 71.6 ± 15.5%); and minimal stent area (9.1 ± 1.6 mm2; 6.1 ± 1.3 mm2). Periprocedural cardiac troponin increased in 1 asymptomatic patient without electrocardiographic change. There was no target lesion failure (cardiac death, myocardial infarction, target lesion revascularization) at 6-month follow-up.ConclusionsThe Szabo 2-stent technique for bifurcation lesions provided acceptable safety and efficacy at short-term follow-up.
