Myocardial protection: a safe cardioplegic catheter
PA Philips and HD Adams
The administration of cold cardioplegic solution has contributed to the
"safe" time allowable for performance of intricate cardiac procedures under
ischemic arrest. A catheter has been designed that delivers a large bolus
of solution quickly, ensures rapid arrest of cardiac function, and allows
continuous perfusion during the procedure. It permits the safe escape of
air on reestablishment of cardiac function. The catheter can be inserted
and removed through a small aortotomy, thereby preventing undue trauma to a
sclerotic or thickened aorta.
