      RE: Letter Regarding Article, “Optical Coherence Tomography to Optimize Results of Percutaneous Coronary Intervention in Patients With Non-ST-Elevation Acute Coronary Syndrome: Results of the Multicenter, Randomized DOCTORS Study"

      We read with interest the results of the DOCTORS study (Does Optical Coherence Tomography Optimize Results of Stenting) of the use of optical coherence tomography to optimize stent implantation in non-ST-elevation myocardial infarction. The finding that stent underexpansion detected by optical coherence tomography occurs in 42% of implants and often goes undetected by angiography is sobering and calls for the interventional community to rethink current stent implantation strategies. In this study, stents were implanted under high pressure (mean 16 atm). High-pressure implantation in metallic stents has been shown to improve stent expansion, and this practice is common around the world ...

    3. Classification of mechanisms of strut malapposition after angiographically optimized stent implantation: An optical coherence tomography study

      Classification of mechanisms of strut malapposition after angiographically optimized stent implantation: An optical coherence tomography study

      Aims To elucidate causes and extent of strut malapposition in angiographically optimized stenting. Methods and Results Using a new classification system for strut malapposition, the mechanisms of stent strut malapposition were classified as localized lumen enlargement, vessel asymmetry, stent undersizing, strut underexpansion and stent deployment issue. Stent implantations ( n  = 110) in 100 consecutive patients undergoing optical coherence tomography (OCT) after the operator considered the stent as optimally deployed angiographically were reviewed to determine if strut apposition was complete. 127,894 stent struts in 110 stents were analyzed. There were 6,644 struts malapposed (5.2% ±7.3%), with strut malapposition ...

    4. Utility of Frequency Domain Optical Coherence Tomographic Evaluation of Angiographically Optimized Stented Lesions

      Utility of Frequency Domain Optical Coherence Tomographic Evaluation of Angiographically Optimized Stented Lesions

      Background. Given its high resolution, optical coherence tomography (OCT) may be a useful clinical tool to optimize stent deployment. Methods. We reviewed 100 patients with post-PCI OCT who had angiographically optimized coronary stent implantation to determine the frequency of further intervention based on OCT pathology. OCT pathology was classified as “significant” if an OCT finding prompted further intervention. Results. OCT pathology was found in 90% of patients and considered significant in 52%. Stent strut malapposition by OCT was the most common reason for prompting further treatment, with approximately one-half due to relative stent undersizing. Based on OCT findings, 42% underwent ...
