Title and Author Image Guided Cardiac SurgeryKeith A. Horvath Abstract Critical elements to any operation are imaging and access. As a result what drives how cardiac surgeons operate is their obtaining access so that they can see the area of interest and effect a treatment. To reduce trauma minimally invasive approaches have been developed largely based on smaller incisions but are still reliant on direct vision. Other specialties have approached the problem from the opposite direction. Employing the types of imaging with which they are familiar they have devised treatments based more on what the imaging allows than what the access permits. These approaches are typically less invasive as a result. It can be argued however that basing the approach on the imaging rather than the pathology may lead to limitations in the treatment. Typically the balance shifts from more invasive and more durable to less of both. Advances in imaging have surpassed what can be seen with the eye and can in fact allow assessment at the cellular level. This has led to significant improvement in diagnostic capabilities. The next big advance is to move these imaging tools from the diagnostic arena to the therapeutic. Examples of this shift to therapeutic imaging are the use of real time magnetic resonance imaging to provide clear definition of the anatomy as well as function, perfusion and device tracking1; physiologic imaging for revascularization2 and computer modeling for preoperative planning and intraoperative assessment. The major challenge facing future operators is determining the best imaging that will allow the best treatment. Key Research Gap Requiring NHLBI Leadership
