Transthoracic minimally invasive closure for the treatment of ruptured sinus of Valsalva aneurysm: immediate and mid-term follow-up results.

Abstract

BackgroundWe aimed to evaluate the immediate and mid-term outcomes of transthoracic minimally invasive closure (TMIC) of ruptured sinus of Valsalva aneurysm (RSVA), which is a rare and mostly congenital heart disease.MethodsFrom January 2014 to November 2020, 19 patients (16 males, 3 females) with RSVA were selected for TMIC and were followed up at our centre. Data were analysed from our prospectively collected database and clinical mid-term follow-up was obtained.ResultsAmong these 19 cases, transthoracic echocardiography showed rupture of the right coronary sinus to the right atrium in 9 patients, non-coronary sinus rupture to the right atrium in 7 patients, and right coronary sinus rupture to the right ventricle in 3 patients. Most (13/19) cases were New York Heart Association (NYHA) functional class III or IV. The mean diameters of the defect from the aortic end and ruptured site were 8.8±3.0 and 6.4±2.6 mm, respectively. TMIC was attempted using ventricular septal defect (VSD)/patent ductus arteriosus (PDA) occluders 2–7 mm larger than the aortic ends of the defects. All patients were successfully treated by TMIC and achieved complete closure at discharge after a mean hospital stay length of 6.2±2.5 days. Seventeen patients were NYHA class I while 2 patients were NYHA class II. No cases of residual shunts, device embolization, infective endocarditis, or aortic regurgitation were observed during a median follow-up of 36 months (range, 16–84 months).ConclusionsIn appropriately selected cases with RSVA, TMIC is an attractive alternative to surgery, with a high technical success rate and encouraging short-term and mid-term outcomes. However, long-term follow-up is needed.
