This education is designed to examine the diagnosis and intervention of disease states that are studied in the cardiac catheterization laboratory.  Patient case studies will be presented and discussed, from the point of admission or symptom onset, to diagnosis, to the cardiac catheterization laboratory study/intervention performed, concluding with the patient outcome.  When patients in the cases are referred for cardiothoracic and or vascular surgery, those aspects of the cases will also be reviewed.  Discussion of interventions will include technique, successes and pitfalls.  Our goal is to illustrate best practice and provide providers with opportunity to review innovation and revisions in practice.
