In the present study, we describe a modified novel less cumbersome variant of the Penetrating wire technique, called “STABBING”.
To assess the impact of the new Stabbing wire technique as Conventional Initial Strategy on the outcomes of CTO intervention compared to standard CTO wire techniques.
From January to October 2015, a total of 92 patients were recruited from the Cath lab Unit and prospectively evaluated for the study endpoints. All patients with angiography showing chronic total occlusion, and prepared for CTO intervention were included in this study. Coronary angioplasty and re-vascularization achieved in all 92 patients.
These patients were divided into two groups: group A, comprising 46 patients ( PCI done with Stabbing Wire Technique as Conventional Initial Strategy) and group B, comprising 46 patients (PCI done with standard techniques).
There were no significant differences in terms of age, sex, and classical risk factors. Comparing the success rates of ante grate re-vascularization in both study groups, Stabbing wire technique as Conventional Initial Strategy had a significant higher success outcome with significant (p-value 0.01). compared to the other wire techniques strategies. Comparing the time consumption needed for CTO PCI in both study groups, Stabbing wire technique as Conventional Initial Strategy had a significant lower time consumption with significant (p-value 0.02). Comparing the contrast use in both study groups, Stabbing wire technique as Conventional Initial Strategy had a significant lower amounts of contrast used with significant (p- value 0.01). Comparing the economic burden in both study groups, Stabbing wire technique as Conventional Initial Strategy had a significant lower economic burden with significant (p-value 0.002). This study describes the potential protective effects of the new stabbing wire technique in patients with CTO undergoing PCI with stenting.
These findings may have implications for clinical trials investigating agents and equipment designed to reduce CTO PCI complications. Because CTO PCI became relatively common and carries a lot more challenges and complications, it is imperative for patients with CTO to be identified in clinical trials. This implies that modifying our techniques, upgrading our practice and education promoting should be emphasized in future, which may further shorten the time of CTO PCI and reduce the hazards it carries.
