Coronary artery stenting has evolved substantially since the first use of coronary stenting as an adjunct to balloon angioplasty in the early 1990s. The performance (and particularly the deliverability) of coronary stents has improved such that coronary stenting is now the primary mode of revascularisation for percutaneous coronary interventions (PCIs) in more than 95% of cases. The new Svelte™ stent-on-a-wire (SOAW) delivery system represents one of the first substantive innovations in stent delivery systems (SDS) in more than a decade. This SDS uses a shapeable ‘fixed wire’ as an integral part of the SDS. This allows a significant reduction in SDS profile (~0.029 inches) compared with conventional monorail or over-the-wire SDS. This SOAW SDS is intended to facilitate direct stenting. It has the potential to provide substantial procedural cost savings by eliminating the need for a coronary guidewire and balloon pre-dilatation and/or post-dilatation, and by reducing contrast use and the time required to complete the procedure. The SOAW system is compatible with 5Fr guiding catheters, and may reduce the need for closure devices, facilitate stenting via the radial approach and (potentially) reduce bleeding risks. In conclusion, the Svelte SOAW SDS represents a new very-low-profile balloon-expandable SDS that should promote direct stenting in PCIs. The efficiency and small profile of this SDS may allow procedural cost savings, a reduction in procedure time and a reduced risk of bleeding complications. These theoretical advantages will need to be demonstrated in clinical trials.

<p><strong>Background</strong>. No-reflow phenomenon during primary percutaneous coronary intervention (PCI) is a significant clinical problem in patients with ST-elevation myocardial infarction (STEMI), and its predictors remain unclear.</p><p><strong>Aim</strong>. To develop a scoring system to predict the risk of no-reflow in patients undergoing PCI for STEMI.</p><p><strong>Methods</strong>. Data were collected from 1280 consecutive patients with STEMI (59.2±11.4 years, 74.2% men, 5.2% no-reflow) who were admitted to the coronary care unit and underwent PCI. Baseline clinical, angiographic and procedural variables were used to develop the risk score in a training dataset (n=888, 70%) which was then validated in a test dataset (n=392, 30%). A credit risk assessment tool was used to construct a precise screening tool for no-reflow.</p><p><strong>Results</strong>. The model comprised age, pain to revascularisation time, neutrophil count, admission plasma glucose level, initial TIMI flow and direct stenting as the only independent predictors of no-reflow. These factors were weighted and used to develop a risk score ranging from 0 to 7. In the training dataset, the optimal threshold score for predicting no-reflow was ≥35, with 69% sensitivity and 81% specificity (area under the curve (AUC) = 0.84, p &lt; 0.001). When these findings were applied to the test dataset, the AUC was 0.75 (p &lt; 0.001), with 70% sensitivity and 80% specificity.</p><p><strong>Conclusion</strong>. The score developed in this study, based on clinical, angiographic and procedural features, can be used with acceptable accuracy to predict no-reflow in STEMI patients treated by PCI.</p><p>Received 29 August 2019. Revised 25 March 2020. Accepted 16 April 2020.</p><p><strong>Funding:</strong> The study did not have sponsorship.</p><p><strong>Conflict of interest:</strong> Authors declare no conflict of interest.</p>
