Perforation of the right ventricle by a suction drain.

Suction drains can be used as alternatives to conventional underwater seal drains following cardiac surgery, and may be advantageous under some circumstances. The authors present a case where a suction drain eroded into the right ventricle causing near-fatal haemorrhage following coronary artery surgery. Caution should be exercised in taking the decision to use suction drains, the material from which they are manufactured should be chosen carefully, and close attention paid to their positioning within the mediastinum.
