evaluate the role of myocardial performance index (Tei index) in assessing left ventricular function in patients with valvular mitral regurgitation (VMR).

A case control study conducted at Iraqi center for heart disease, Ibn Al-Naffees and Ibn Al-bitar hospitals for cardiac disease. The study included 50 patients with VMR and 50 subjects as control. All participants were subjected to full echocardiographic study (in left lateral decubitus position including left ventricular systolic and diastolic function), myocardial performance index (Tei index) calculated

Left ventricular ejection fraction (LVEF) was normal to all patients with mild mitral regurgitation (MR), 87% of patients with moderate MR had normal LVEF, and 92.2% of patients with severe MR had normal LVEF. There was an increase in left ventricular end systolic dimension with increase in grading of MR. Tei index was increased with higher level of MR severity, and in affected before the decline in EF.

Myocardial performance index is good and easily determined index in the assessment of left ventricular function in patients with MR and myocardial performance index has the ability to detect LV dysfunction earlier than ejection fraction.
