Interventional cardiology has grown leaps and bound in the last few decades .We are able to clip the wings of mitral valve without surgery when it prolapses
We can deliver a huge aortic valve and fix it with wires .
But . . . we have no proper preformed guiding catheter that can sit into RCA ostium directly and snugly for a long time to enable complex RCA angioplasties !
An now try this one .
Here is a pending patent for a preformed RCA catheter
