Key result
Stenting of the entry point at the coronary ostia successfully restored normal flow and sinus rhythm in a patient with iatrogenic right coronary cusp dissection.
Why the study?
Iatrogenic coronary artery dissection during catheter engagement is not uncommon, but iatrogenic right coronary cusp dissection is relatively rare.

Stenting of the entry point at the coronary ostia is an effective treatment for iatrogenic coronary ostia dissection with aortic cusp involvement.
May support bailout stenting in rare iatrogenic cusp dissections; leaves open generalizability and safety.
Iatrogenic dissection of coronary arteries while performing catheter engagement, in general is not uncommon. However, we encountered a relatively rare case of iatrogenic right coronary cusp dissection.Here we report an iatrogenic coronary artery dissection after diagnostic angiography in a 54-year-oldwoman presented with exertional dyspnea and chest discomfort. In our case delayed progression of sub-intimal hematoma and subsequent compression of RCA ostium an SA node branch was the cause of SA node dysfunction and subsequent junctional rhythm and atrial fibrillation. To conclude it should be said that in catastrophic cases of iatrogenic coronary ostia dissection and ensuing aortic cusp involvement, stenting of entry point at coronary ostia is a logical decision with good result.

Eshraghi et al. (2020) conducted a case report in Iatrogenic right coronary cusp dissection (n=1). Stenting of coronary ostia was evaluated on Restoration of vessel patency and resolution of symptoms. Stenting of the entry point at the coronary ostia successfully restored normal flow and sinus rhythm in a patient with iatrogenic right coronary cusp dissection.
