- Primary Outcome Measures
Name Time Method Primary outcome: Differences in time to peak systolic velocity between different segments of the right ventricle: <br /><br>- Right ventricular outflow tract<br /><br>- Right ventricular free wall<br /><br>- Right ventricular septum. <br /><br /><br>The greatest difference in time to peak systolic velocity of the segments (latest peak systolic velocity minus earliest peak systolic velocity) will be used as a measure of dyssynchrony, and this value will be compared before and after PVR<br><br><br>
- Secondary Outcome Measures
Name Time Method Effect of PVR on ventricular function<br>(eg. volume, diastolic function, E/A ratio, pulmonary regurgitation, Vo2 max, clinical condition)
