title: Simplified circular aortotomy in aortocoronary bypass operations.
abstract: Adaptation of a rongeur technique facilitates aortotomy in aortocoronary bypass operations. A single motion with a double-action duckbilled rongeur produces a smooth-walled, symmetrical aortotomy which varies in shape predictably according to the angle at which the rongeur is held relative to the axis of the aorta.
