Upfront 2-stent techniques are often used in bifurcation percutaneous coronary interventions (PCI), but there is controversy about optimal strategy selection.
The authors examined the clinical and angiographic characteristics and long-term outcomes of 232 bifurcation PCIs that were performed using the double kissing (DK) crush or culotte technique in 216 patients between 2014 and 2023 using data from the Prospective Global Registry for the Study of Bifurcation Lesion Interventions (NCT05100992). The inverse probability of treatment weighted (IPTW) Cox proportional hazards model was used to assess long-term outcomes.
DK crush was more commonly used (69.0%). Patients in the DK-crush group had similar baseline characteristics to those in the culotte group. Lesions treated with DK crush were more likely to be in the left main coronary artery (42.9% vs 15.5%, P less than .001), had larger proximal (3.50 [3.50-4.00] vs 3.50 [3.21-3.79] mm, P = .027) and distal (3.00 [3.00-3.50] vs 3.00 [2.75-3.25] mm, P = .047) main vessel diameter, and were more likely to have severe calcification (29.8% vs 5.6%, P less than .001). Technical (98.8% vs 97.2%, P = .588), procedural success (96.5% vs 95.1%, P = .698), and in-hospital major adverse cardiovascular events (MACE) (6.1% vs 3.0%, P = .509) were similar in both groups. During a median follow-up of 43 months, 60 (33.9%) patients experienced MACE. On IPTW adjusted Cox analysis, DK crush was associated with lower follow-up MACE (hazard ratio 0.28; 95% CI, 0.13-0.60; P = .001) compared with culotte driven by lower target vessel revascularization (TVR) (14.3% vs 29.3%, P = .029).
Compared with culotte, DK crush is associated with similar periprocedural outcomes but lower TVR and MACE during follow-up.
在分叉病变经皮冠状动脉介入治疗（PCI）中，初始双支架技术经常被使用，但在最佳策略选择方面存在争议。
作者使用前瞻性全球分叉病变介入治疗研究注册库（NCT05100992）的数据，研究了2014年至2023年间216例患者中采用双吻（DK）挤压或裤裙技术进行的232例分叉病变PCI的临床和血管造影特征及长期结局。采用治疗加权逆概率（IPTW）Cox比例风险模型评估长期结局。
DK挤压技术使用更为普遍（69.0%）。DK挤压组患者的基线特征与裤裙组相似。DK挤压技术治疗的病变更可能位于左主干冠状动脉（42.9%对15.5%，P＜0.001），近端（3.50[3.50 - 4.00]对3.50[3.21 - 3.79]mm，P = 0.027）和远端（3.00[3.00 - 3.50]对3.00[2.75 - 3.25]mm，P = 0.047）主血管直径更大，且更可能有严重钙化（29.8%对5.6%，P＜0.001）。两组的技术成功率（98.8%对97.2%，P = 0.588）、手术成功率（96.5%对95.1%，P = 0.698）和院内主要不良心血管事件（MACE）发生率（6.1%对3.0%，P = 0.509）相似。在中位随访43个月期间，60例（33.9%）患者发生MACE。在IPTW调整的Cox分析中，与裤裙技术相比，DK挤压技术与较低的随访MACE相关（风险比0.28；95%CI，0.13 - 0.60；P = 0.001），这是由较低的靶血管血运重建（TVR）率驱动的（14.3%对29.3%，P = 0.029）。
与裤裙技术相比，DK挤压技术围手术期结局相似，但随访期间TVR和MACE较低。
