It most often involves the right coronary sinus and less frequently the non-coronary sinus 3.

Demographics and clinical presentation

There may be a slight male predilection. Presentation with a catastrophic acute rupture is quite common.

Radiographic features

Cardiac MRI

Considered the imaging modality of choice especially with the mycotic type. features to be added


  • rupture : leading to tamponade +/- intra cardiac shunting
  • ventricular outflow tract obstruction


Surgical repair with a Bentall procedure could be performed.
