Transseptal approach versus left atrial approach to mitral valve: a propensity score matching study

ABSTRACT

Background: Many patients with mitral valve diseases need surgical procedures for the repair or replacement of their mitral valve. There is a great deal of controversy over the outcomes of the transseptal [TS] and left atrial [LA] approaches to the mitral valve. We sought to evaluate the outcomes of each approach more accurately by eliminating the possible biases in case selection and matching
