At 12 years old, patient exhibits shortness of breath
(class II) that progresses to class III in the third postoperative
year. |
April 2016 |
At 13-year-old, she was presented with severe SOB and
admitted to the hospital. |
|
A transthoracic echocardiography shows a degenerated bioprosthetic
mitral valve and severely dilated right ventricle with significantly
depressed function. Severe mitral stenosis was observed (mean pressure
gradient of 18 mm Hg). |
|
The heart team discussed the case and opted not to perform surgery.
The team recommended a transcatheter mitral valve
replacement. |
|
The transcatheter mitral valve replacement was successfully completed.
The patient’s mean pressure gradient with the new valve was 5 mm Hg.
After extubation, the patient was moved to the intensive care unit and
then discharged after 2 days. |
Follow up after 30 months |
At the patient’s 30-month post-procedure
follow-up, she reported regular daily activity with no shortness of
breath. A follow-up transthoracic echocardiography revealed that the
right ventricle had reduced in size and demonstrated normal function.
The systolic pulmonary artery pressure reduced to 33 mm Hg, the mean
pressure gradient of the left ventricular outflow tract was 10 mm Hg,
and the mitral valve mean pressure gradient was 6 mm Hg. |
