The purpose of this study is to identify patients presenting to the echocardiogram laboratroy for routine clinically indicated echocardiography or to the cardiac catheterization laboratory for routine clinically indicated catheterization procedures.

Spontaneous Coronary Artery Dissection: Mechanistic Evaluation.

Predict the development of clinical heart failure/.

Predict future reductions in LVEF (cardiotoxicity) or in the case of cardiac rehabilitation, prevention of LVEF decrease/.

Occur before changes in resting strain or resting LVEF/.

The study will also determine whether changes after treatment with cancer therapeutics or a period of cardiac rehabilitation in any of the aforementioned parameters of cardiac function with low intensity exercise:

Mitral valve inflow velocities (E, A) and mitral annular tissue Doppler (e’, a’).

LV circumferential and radial strain and strain rate.

Right ventricular (RV) longitudinal strain and strain rate.2D and 3D left ventricular (LV) longitudinal strain and strain rate.The purpose of this study is to determine whether changes in the following parameters of cardiac function with low intensity exercise occur following (1) treatment with cancer therapeutics or (2) cardiac rehabilitation:
