Chest X-Ray. 3. Cardiac computed tomography (CT) scan. 4. Echocardiogram (echo). 5. Electrocardiogram (ECG/EKG). 6. Left and right heart catheterization.
Treatment depends on your condition and its severity. Your provider will talk with you about your treatment options and the urgency of your situation. Some common options include: 1.

Enclosed within the mediastinum, the medial cavity of the thorax, the heart extends obliquely from the second rib to the fifth intercostal space. It rests on the superior surface of the diaphragm, lies posterior to the sternum and ...
The inner visceral layer is also called the epicardium and it lines the surface of the heart. Between these two membranes is a space, the pericardial cavity, containing a small amount of fluid to reduce friction as the heart moves. Both layers have mesothelium which produces serous fluid.
