OBJECTIVE: To evaluate the effects of controlled ovarian hyperstimulation (COH) treatment on cardiac functions using tissue Doppler imaging (TDI).STUDY DESIGN: Twenty-one patients aged 22-35 years were enrolled to COH cycles. Each subject underwent a conventional transthoracic echocardiographic examination that included an assessment of cardiac function. Measurements were taken twice--the first on the second day of the cycle and the second on the day when human chorionic gonadotropin was administered. Twenty-one healthy women were chosen for the control group.RESULTS: The COH treatment did not cause favorable cardiac function changes. The parameters showing the left ventricular diastolic function such as early diastolic peak flow velocity (E), late diastolic peak flow velocity (A), mitral E/A ratios, mitral E wave, deceleration time (DT), lateral isovolumic relaxation time (IVRT), and left ventricular myocardial performance index (LVMPI) were not changed. The COH treatment did not affect the right ventricular diastolic functions such as tricuspid valve E wave, DT, right ventricular (RV) IVRT, or right ventricular myocardial performance index (RVMPI). Concurrently, the COH treatment showed no effects on the right and left ventricular systolic functions.CONCLUSION: TDI findings reveal no effects of the COH treatment on cardiac function.
