<p>Robotic approach allows to harvest bilateral thoracic
arteries using 5 ports (8 or 12 mm) in the left chest with no thoracotomy or
sternotomy. This allows for a quick recovery with early post-operative
discharge from the hospital (POD 2 or 3) and a quick return to daily activity:
the absence of any thoracotomy or sternotomy makes the post-operative pain
minimal and return to daily activity the quickest among any other minimally
invasive coronary bypass surgical approach. </p>
<p>By adopting a robotic platform, surgeons can harvest both
thoracic artery conduits nullifying the risk of sternal wound infection.
Independently from BMI, gender or HbA1C, bilateral thoracic arteries (BITA) can
be chosen as the grafts of choice in all comers. The only relative contra
indication for robotic BITA take down are: 1) previous left thoracic surgery
and 2) intolerance to single lung ventilation. </p>
<p>The international reports of BITA harvest via thoracotomy or
endoscopically assisted, have showed a very complex selection criteria required
for such techniques due to the challenging in visualizing the mammary arteries
via a small thoracotomy and the difficulties in maneuvering the long-shafted
instrument inside the chest cavity. The robot allows increased operative
dexterity and tremor-free movement with high-powered, magnified vision.
Articulating instruments move with seven degrees of freedom and do not face the
fulcrum effect which is typical of long-shafted, endoscopic instruments.</p>
<p>In a closed chest environment, the RITA is actually closer
to the heart than generally perceived in an open sternotomy case and can reach
left side targets passing underneath the anterior mediastinal fat. Finally, the
value of BITA conduits even in incomplete revascularization has been proved to
be superior to single internal thoracic artery and multiple veins coronary
surgery even when the latter achieve complete revascularization.</p>

<p>We present here the detailed techniques and surgical notes
on how to harvest bilateral thoracic arteries by using a robotic platform. We
decided to divide the steps into 5 checklist that needs to be completed to
achieve the final goal of obtaining two excellent grafts ready to be deployed
on the heart. </p>
