Post Procedural Echocardiography
At six weeks three patients showed a significant improvement in the
LVEF, compared to the pre-TAVI echo, two patients had a 10% improvement
in their LVEF, and one patient showed a 20% improvement in EF. At six
weeks no patients had a sustained reduction in their EF of more than
7%. Unfortunately, three of 19 TTEs were not available for analysis at
six weeks.
