A randomized controlled trial of drug-coated balloon angioplasty in venous anastomotic stenosis of dialysis arteriovenous grafts.

Objective: Paclitaxel-coated balloons are used to reduce neointimal hyperplasia in native arteriovenous (AV) fistulas. However, no study specifically evaluated their effect on venous anastomotic stenosis of dialysis grafts. We aimed to compare the efficacy of angioplasty with drug-coated balloons (DCBs) and angioplasty with conventional balloons (CBs) for venous anastomotic stenosis in dysfunctional AV grafts.

Very late recurrence of sinus of Valsalva aneurysm rupture after patch repair.

Background: Sinus of Valsalva aneurysm (SVA) is an uncommon cardiac defect accounting for only 1% of congenital cardiac anomalies and the most common complication is ruptured into the atrium or ventricle. Very late recurrence of ruptured SVA after patch repair is extremely rare.

Case Presentation: We present a case of 57-year-old man had received repair for ruptured Sinus of Valsalva aneurysm at 19 ages.
