Interventional cardiology and general cardiology: divided by a common speciality?

For a couple of years now, the annual meeting of the American College of Cardiology (ACC) consists of two separate meetings: the conventional ACC meeting and the SCAI-ACCi2 (Society for Cardiovascular Angiography and Interventions) meeting. The SCAI-ACCi2 meeting is specifically intended for interventional cardiologists and in order to attend the meeting one has to pay either a special entrance fee for this meeting or an additional fee to attend both meetings. Even Fellows of the ACC are not allowed into this dedicated interventional meeting (unless they pay the additional entrance fee). At the ACC.08 meeting in Chicago this year, the general cardiologist (ACC.08) could be recognised by a blue badge and the interventional cardiologist by a yellow badge (SCAI.ACCi2).
