The shunt allows the continued perfusion of the coronary outflow area during most of the anastomosis time.
It needs to be available in the operating suite in sizes from 1 to 3 mm. Shunting will be discussed later.
We observed no negative effect on hemodynamics and with a negative suction of -200 mmHg,
it is rare to observe a “chignon” that
last more than seconds.
This is our preferred apical positioner.
