Optical coherence tomography guided additional Noevas bioresorbable vascular scaffold in the treatment of iatrogenic coronary artery dissection: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIatrogenic coronary artery dissection is a potential complication during percutaneous coronary bioresorbable vascular scaffolds placement. We report that significant dissection occurred during post-expansion of the left circumflex branch bioresorbable vascular scaffolds to attach it to the wall. Additional resorbable stents successfully covered the dissection without blood flow restriction. CASEREPORT: The patient was a 49-year-old male with refusing intracoronary metal stents and was diagnosed with stable angina pectoris and type 2 diabetes. Coronary angiography showed serious lesions in three vessels. A Noevas stent was had placed in the proximal segment of the anterior descending branch. Unfortunately a type-D dissection occurred during post-dilatation after the second scaffold was placed in the proximal of the circumflex branch. A third scaffold was inserted to cover the dissection and optical coherence tomography reexamination showed good apposition. After 6 months of coronary angiography, optical coherence tomography examination showed no deterioration of the circumflex branch dissection, and the proximal intimal hyperplasia in the proximal scaffold was 95%. Scoring balloon and drug balloon dilatation were successfully performed, and right coronary artery dilatation with drug coated balloon was performed. The patient had no symptoms of chest pain after 2 years of follow-up.
conclusionAdditional bioresorbable vascular scaffold coverage of coronary type-D dissection with the help of imaging tools may be a practical strategy when patients selcet for coronary metal-less implantation. Furthermore, imaging review is recommended especially for diabetics.
