Minimally Invasive Transthoracic Device Closure of an Acquired Sinus of Valsalva-Right Ventricle Fistula in a Pediatric Patient

Background: sinus of valsalva-right ventricle fistula is a recognized but very rare complication after surgical repair of subaortic ventricular septal defect. surgical repair with cardiopulmonary bypass and percutaneous transcatheter closure guided by x-ray has been the traditional treatment for fistula of sinus of valsalva. case presentation: recently, we have used a novel approach, that avoids the need for either secondary open surgical repair or radiation exposure; that is, minimally invasive transthoracic device closure guided by transesophageal echocardiography to occlude an acquired sinus of valsalva-right ventricle fistula in a 4-year-old patient. conclusion: to our knowledge, there have been no prior cases reported of this technique applied to close an acquired sinus of valsalva-right ventricle fistula. this report aims to provide a detailed description of the procedure.
