Abstract :
Cor-triatriatum sinister (CTS) is a rare congenital condition in which
the left atrium is divided into two chambers. Patients can present as
infants or later in life, which is largely dependent on the size of
fenestration between these two chambers. Surgical excision of the
membrane is curative. This is traditionally performed through a median
sternotomy. Here we report of a case of a 60-year old man who presented
to his primary care physician with dyspnea and atrial fibrillation. He
was found to have CTS. We performed excision of the left atrial membrane
and maze procedure through a left anterolateral mini-thoracotomy with
femoral cannulation.
