Early post-operative pulmonary function tests after mitral valve replacement: Minimally invasive versus conventional approach. Which is better?

Minimally invasive right anterolateral mini-thoracotomy is as safe as median sternotomy for mitral valve surgery, with fewer complications and postoperative pain, less ICU and hospital stay, fast recovery to work with no movement restriction after surgery. There was a highly significant difference denoting better post operative pulmonary function of the minimally invasive approach.
