A New Contribution to Cardiothoracic Surgical Education

There is nothing more satisfying for a clinician than when a patient understands their ailment, comprehends the nature of the pathology involved, and is clear on the treatment/procedure they are about to undergo. This "satisfaction" is a joyous emotion reflecting successful communication -- it is what parents feel when their children first begin to read, and what educators aspire to when their students master the material at hand.

It is a privilege to share our most recent contribution to the cardiothoracic surgery community, the TSRA Primer of Cardiothoracic Surgery...
