The goal of the echocardiography rotation is to gain a full understanding of the role of noninvasive diagnostic testing in contemporary clinical cardiology. The fellows will learn all the applications of the following noninvasive modalities during the course of this rotation:
• Transthoracic echocardiography
• Transesophageal echocardiography
• Stress echocardiography (treadmill and pharmacologic)
• Treadmill stress testing
• Interpretation of electrocardiograms
• Interpretation of holter monitors and 30-day event monitors
Given the complexity and array of contemporary noninvasive diagnostics, it is recognized that multiple one-month rotations will be required for mastery of all of the techniques. Fellows spend a minimum of six months during the three year program rotating through the heart station. There are three fellows (generally one from each year) on this rotation at any time. During this period the trainee is directly supervised by one of five non-invasive attendings.
On a daily basis, non-invasive rounds are held with the non-invasive attending and each test is reviewed , and the fellow's interpretation is discussed and, if need be, revised.
There is ample opportunity for fellows to obtain "hands-on" experience in performing echocardiograms. Trained, certified sonographers supervise the performance of one study per day performed by the fellow; this study is subsequently reviewed by the non-invasive attending. This experience provides valuable training for fellows and enhances appreciation of how technical aspects of the ultrasound examination impact the ultimate quality of the data. Fellows also gain extensive experience with quantitative aspects of echocardiography during their rotations and gain familiarity with measurements of left ventricular mass, volume, fractional shortening, and wall stress. Fellows are encouraged to perform quantitative analysis of studies using the off-line analysis systems both for clinical and research studies.
Fellows also have responsibility for EKG interpretation and for performance and interpretation of exercise treadmill tests while on the heart station rotation. Exercise treadmill testing is performed in the heart station as well as nuclear cardiology. The heart station is one of three inpatient sites for exercise treadmill testing (in addition to nuclear cardiology and the fitness center). The heart station generally performs exercise tests on cardiology inpatients on the medical service and for vascular surgery patients, undergoing evaluation for intermittent claudication. Approximately five exercise tests are performed per day in conjunction with experienced technicians; the fellow is responsible for obtaining the patient's clinical history, performing an examination, and for supervising and providing an interpretation of the test. A preliminary note is written in the patient's chart; the report is subsequently reviewed with the non-invasive attending later that day.
