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.

Device loss or entrapment during percutaneous coronary interventions (PCI) is a rare circumstance whose incidence has decreased over time mainly because of device improvements. Nevertheless, they still represent fearful complications also and above all because the operators may be unfamiliar with rescue and retrieval techniques. The devices that most frequently experience loss or entrapment are stents, followed by angioplasty balloons, burrs for rotational atherectomy, guidewires and microcatheters. In this review we will illustrate the risk factors for device loss and the main retrieval techniques, as described in the literature or stemmed from our experience as high-volume PCI center.

The growing number of research on quality of life is stimulated by the need to compare therapeutic treatments that have a similar efficacy to reduce mid- and long-term mortality, but that can warrant different levels of quality of life. The aim of this review was to describe theories and applications of different questionnaires (generic vs specific), methodology to construct a new questionnaire, and the methods of translation and cross-cultural adaptation in another language. Finally, the characteristics of the Coronary Revascularization Outcome Questionnaire, a validated instrument that measures symptoms, physical, psychosocial and cognitive function, adverse effects and satisfaction with treatment for bypass surgery and coronary angioplasty are described. The Italian version is actually used in a multicenter trial in several heart surgery and interventional departments.
