SR Print(0) ID 1146594637 T1 Cardiac Anatomy for the Interventionalist T2 Interventional Cardiology, 2e YR 2017 FD 2017 PB McGraw-Hill Education PP New York, NY SN 9780071820363 LK accesscardiology.mhmedical.com/content.aspx?aid=1146594637 RD 2024/10/10 AB This chapter on cardiac anatomy takes a practical approach for operators who are going to perform various procedures associated with structural heart disease. Rather than assume the traditional approach of describing the gross anatomy of the heart in isolation from the procedures performed, this chapter will attempt to provide useful information (Tips and Tricks) of how the anatomy, as seen by the percutaneous operator, affects the procedure results. Therefore, the emphasis is not only on gross anatomy, but also the anatomy that the interventionalist perceives using different imaging modalities. Whereas a surgeon can see and touch the anatomic structures, a cardiac interventionalist has to rely on indirect methods of visualization, which include fluoroscopy, echocardiography, and intracardiac ultrasound. Magnetic resonance or computed tomography images can be useful for orientation and diagnosis before the procedure (and, more recently, can be used as an overlay on the fluoroscopy monitor in the catheterization lab). However, the focus of this chapter is what the interventionalist has at his or her disposal at the time of the procedure to understand the anatomy. Accurate use of available imaging modalities in the catheterization laboratory and appreciation of relative orientations are important for optimal device sizing and placement.
