Mitral regurgitation (MR) may be classified into two major categories: primary and secondary (functional). In primary MR, disease of the valve itself (eg, myxomatous degeneration, rheumatic disease) causes valve incompetence, producing left ventricular (LV) volume overload. To compensate, the left ventricle must enlarge in order to increase its volume-pumping capacity. ...
