The mitral valve surgery volume has remained steady over the last 5 years.
Many of these procedures repair the mitral valve instead of replacing it.
Mitral valve repair procedures account for over 99% of the mitral valve procedures performed on patients with degenerative mitral valve disease.
Only 3 out of 372 mitral valves with degenerative disease were replaced over the last 5 years.
Mitral valve procedures performed via thoracotomy include complex redo operations, as well as primary minimally invasive procedures.
More than three quarters of the mitral valve procedures are repairs.
