Simple Diagnostic Tools May Guide Transcatheter Closure of Superior Sinus Venosus Defects Without Advanced Imaging Techniques

Transesophageal echocardiography and balloon interrogation identified 60% of the patients with sinus venosus defects to be eligible for catheter closure. Overlapping stents are an alternative to custom-made long stents. Transesophageal echocardiography confirms procedural success on follow-up. Advanced imaging and printing technologies are not essential for successful outcomes and thus simple tests increase the feasibility in developing countries.
