[Percutaneous treatment of pulmonary embolism: diffusion and use of the technique in Italian interventional cardiology centers. Results of the PETER survey].

BACKGROUND Reperfusion in acute pulmonary embolism (PE) by percutaneous techniques is a valid therapeutic option when there is a formal contraindication to or failure of thrombolysis. In the last years, an increasing number of patients with acute PE have been treated with these techniques. METHODS In order to obtain a map of current availability and use of percutaneous techniques in PE, on behalf of the ANMCO Pulmonary Circulation Area, 56 Italian interventional cardiology and radiology departments, equipped with technology for percutaneous embolectomy, were invited to participate in a national survey. Questionnaires were e-mailed to each department from April to May 2015. RESULTS Thirty-one out of 56 centers (54.8% in the North, 9.7% in the Center and 35.5% in the South of Italy) answered to the questionnaire. Percutaneous techniques were available in 90% of the cardiology departments involved, reporting also a good experience with their use in PE (77.4%). Only two responders were interventional radiology departments. AngioJet(®) and EkoSonic Endovascular System(®) (64.7% and 19.4%, respectively) were the most common devices used. Overall, in 2014, 62 patients were treated with percutaneous techniques, mainly in the North of the country. With regard to local diagnostic and therapeutic protocols, 61.3% of respondents reported owning one. Great interest was provided by participants in adhering to this national multicenter registry. CONCLUSIONS Our results show the interest of Italian cardiology departments about percutaneous techniques as a therapeutic option for acute PE. Percutaneous techniques are largely available but still underused in routine clinical practice.
