Background: The Amplatzer™ Trevisio™ Intravascular Delivery System (Trevisio DS; Abbott Laboratories, Chicago, IL, USA) facilitates the delivery of Amplatzer™ Occluders and features an ultraflexible tip, which improves assessment of occluder position before release., Aims: To assess the safety and efficacy of the Trevisio DS for transcatheter closure of patent foramen ovale and atrial septal defect., Methods: The Amplatzer™ Trevisio™ Intravascular Delivery System Post-Approval Study was a prospective, postmarket, single-arm, multicentre, observational study of the Trevisio DS. Enrolled patients were indicated for transcatheter closure of patent foramen ovale or atrial septal defect. In all procedures, the Trevisio DS was used to deliver Amplatzer™ Occluders. Technical success was defined as successful deployment and release of at least one occluder. Device- or procedure-related serious adverse events were tracked until discharge or day 7, whichever occurred earlier., Results: The study enrolled 144 patients with patent foramen ovale and 107 patients with atrial septal defect at 22 European sites; 53 patients with atrial septal defect (49.6%) were aged<18years. The rate of technical success was 98.4% (97.2% for atrial septal defect, 99.3% for patent foramen ovale). There was one serious adverse event (0.4%), an acute periprocedural device embolization that occurred after occluder release in a patient with atrial septal defect; the device was retrieved percutaneously. This was determined by the implanter to be unrelated to the performance of the Trevisio DS., Conclusions: The Trevisio DS exhibited a high rate of technical success and an excellent safety profile during transcatheter closure of patent foramen ovale and atrial septal defect., (Copyright © 2023 Abbott Laboratories.

Superior sinus venosus defect is a communication between the right and left atrium located above the upper margin of the oval fossa, immediately inferior to the junction of the superior vena cava and the right atrium. It is systematically associated with partial anomalous pulmonary venous drainage, especially of the right upper pulmonary vein. Surgical repair has been the gold standard approach to close that defect. Introduced in 2014, percutaneous closure has gradually become a safe and effective alternative to surgery in carefully selected patients, although worldwide experience remains limited. This article provides an appraisal of the patients' selection process and a step-by-step description of the procedure as well as a comprehensive review of its outcomes., Competing Interests: Funding Support and Author Disclosures This work was supported by the French Federation of Cardiology (to Dr Hascoet) and the French Society of Cardiology (to Dr Batteux).

Purpose of the Review: Percutaneous closure of sinus venosus atrial septal defects (ASD) using covered stent implantation is a new and promising minimally invasive technique. New imaging tools are used to ensure preoperative anatomical characterization and preoperative guidance, which are key procedural success factors. Here we will describe and analyze these recent developments., Recent Findings: Sinus venosus ASDs present a wide variety of anatomical features which must be described and analyzed using various imaging tools, including 3D technology. Percutaneous closure is challenging, but can hasten clinical recovery compared to the gold-standard conventional open-heart surgery. The feasibility of percutaneous closure relies on precise preoperative anatomical study and on real-time guidance using a multimodal fusion imaging process. Three-dimensional modeling of sinus venosus ASD is essential to understand the large anatomical panel encountered in this pathology. Multimodal fusion imaging guidance is very useful for performing sinus venosus ASD percutaneous closure in selected patients., (© 2021.
