Perforation of the sinus of Valsalva by guiding catheter during the percutaneous coronary intervention via the right transradial approach: a very unusual complication.

Iatrogenic dissection of the sinus of Valsalva or of the ascending aorta is a rare but potentially fatal event, during the percuteneous coronary intervention (PCI). We reported a case of perforation of the sinus of Valsalva by guiding catheter during PCI via the right transradial approach (TRA) successfully managed and sealed without any sequelae. The choice of guiding catheter into the right TRA should be done carefully and its manipulation should be performed with caution in the coronary artery and in the sinus of Valsalva.
