Three-Dimensional Transesophageal Echocardiography to Assess Right Ventricular Function by Pressure-Volume Loops during Left Ventricular Assist Device Surgery
Not Applicable
- Conditions
- Severe heart failure requiring left ventricular assist device
- Registration Number
- JPRN-UMIN000024698
- Lead Sponsor
- ational Cerebral and Cardiovascular Center
- Brief Summary
Right ventriculoarterial coupling increased significantly after LVAD implantation, suggesting that the efficiency of RV performance improved. Although RVSWI was similar between before and after LVAD implantation, the shape of the RV-PVC changed markedly after LVAD implantation. RVMWI increased significantly after LVAD implantation, corresponding to a significantly higher CI to match LVAD flow. These findings indicate that LVAD implantation might not worsen RV function.
