Abstract

Background: Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide, with bifurcation lesions representing a particularly challenging subset due to their complex anatomy and higher risk of adverse outcomes. The Crush and Culotte stenting techniques are two commonly employed strategies for addressing these lesions, each with its own procedural intricacies and potential benefits.


Objective: The primary objective of this study was to compare the outcomes of Crush versus Culotte stenting techniques for bifurcation lesions in Pakistani patients.


Methods: This retrospective observational study was conducted at the National Institute of Cardiovascular Diseases (NICVD) in Karachi, Pakistan, from January 2018 to December 2021. The study included 303 patients aged 18 years or older who underwent PCI for bifurcation lesions, with 151 patients in the Crush stenting group and 152 patients in the Culotte stenting group. Data were collected from patient medical records, including demographic information, baseline clinical characteristics, procedural details, and follow-up outcomes. Statistical analysis was performed using SPSS version 26.0, employing the Student's t-test for continuous variables, the chi-square test for categorical variables, and Kaplan-Meier survival curves with log-rank tests for time-to-event data.


Results: The in-hospital mortality rate was 3.5% in the Crush stenting group compared to 3.0% in the Culotte stenting group (p = 0.80). The 30-day mortality rate was 4.6% in the Crush stenting group and 4.1% in the Culotte stenting group (p = 0.82). The incidence of major adverse cardiac events (MACE) at 6 months was 13.2% in the Crush stenting group versus 12.8% in the Culotte stenting group (p = 0.88). The incidence of contrast-induced nephropathy was higher in the Crush stenting group (8.5%) compared to the Culotte stenting group (6.4%) (p = 0.04). The duration of hospital stay and procedural time were also longer in the Crush stenting group.


Conclusion: There were no significant differences in mortality and MACE between Crush and Culotte stenting techniques. However, Crush stenting was associated with higher procedural complications such as contrast-induced nephropathy and longer hospital stays. These findings highlight the need for personalized treatment strategies and careful management of procedural risks to optimize patient outcomes.
