Does multiple MGuard stent implantation resolve massive right coronary artery dissection during primary PCI in a patient with inferior MI?
Multiple MGuard stent implantation successfully treated a massive right coronary artery dissection complicating a thrombotic lesion during primary PCI.

MGuard stents may serve as bailout in rare dissection cases during primary PCI; hypothesis-generating, prospective data needed before wider use.
Here we report a case of a 79-year-old woman with inferior myocardial infarction, transferred to our cath lab to perform a primary percutaneous coronary intervention (PPCI). During the procedure, a massive dissection complicated the thrombotic lesion of the right coronary artery (RCA). In this case, we decided to use the MGuard stent to treat both the large dissection and the thrombotic lesion. MGuard stent is a combination of a coronary stent merged with an embolic protection device. After multiple MGuard stent implantation we obtained a complete resolution of the coronary dissection obtaining a patent RCA with normal antegrade flow.

Rapacciuolo et al. (2010) conducted a case report in Inferior myocardial infarction with massive right coronary artery dissection (n=1). Multiple MGuard stent implantation was evaluated on Resolution of coronary dissection and restoration of antegrade flow. Multiple MGuard stent implantation successfully treated a massive right coronary artery dissection during primary percutaneous coronary intervention, resulting in a patent artery with normal flow.
