[Percutaneous treatment of intermediate- and high-risk pulmonary embolism: two case reports]. / Trattamento percutaneo dell'embolia polmonare a rischio intermedio e ad alto rischio: due casi clinici.

Pulmonary embolism is the third most common cause of cardiovascular emergency. Risk stratification is crucial in the clinical and therapeutic management of these patients. The latest European guidelines introduced a new classification based on short-term mortality risk stratification, dividing patients into four categories (high, intermediate-high, intermediate-low and low risk). Despite the limited evidence in this field, the percutaneous treatment of pulmonary embolism represents an option of interest; however, correct patient selection and device choice should be better investigated. In this article, we present two case reports of patients with intermediate-high-risk and high-risk pulmonary embolism treated with the EkoSonic Endovascular System (EKOS Corp., Bothell, WA, USA) and the FlowTriever System (Inari Medical, Irvine, CA, USA), respectively.

Everolimus-eluting bioresorbable vascular scaffolds for treatment of complex chronic total occlusions.

AIMS: Bioresorbable vascular scaffolds (BVS) represent a novel therapeutic option for the treatment of coronary artery diseases. The objective of this study was to evaluate the feasibility of BVS implantation in complex chronic total occlusions (CTO). METHODS AND RESULTS: The present report is a multicentre registry evaluating results after BVS deployment in challenging CTO lesions, defined as J-CTO score ≥2 (difficult or very difficult). A total of 105 patients were included in the present analysis. The mean J-CTO score was 2.61 (difficult 52.4%, very difficult 47.6%). Device success and procedural success rates were 98.1% and 97.1%, respectively. The retrograde approach was used in 25.7% of cases. After wire crossing, predilatation was performed in all cases with a mean predilatation balloon diameter of 2.73±0.43 mm. The mean scaffold length was 59.75±25.85 mm, with post-dilatation performed in 89.5% of the cases and a mean post-dilatation balloon diameter of 3.35±0.44 mm. Post-PCI minimal lumen diameter was 2.50±0.51 mm and percentage diameter stenosis 14.53±10.31%. At six-month follow-up, a total of three events were reported: one periprocedural myocardial infarction, one late scaffold thrombosis and one additional target lesion revascularisation. CONCLUSIONS: The present report suggests the feasibility of BVS implantation in complex CTO lesions, given adequate lesion preparation and post-dilatation, with good acute angiographic results and midterm clinical outcomes.
