Epsilon-aminocaproic acid is routinely used to reduce bleeding during cardiac surgery. Anecdotal reports of thrombotic complications have led to speculation regarding this drug's safety. We investigated the association between epsilon-aminocaproic acid administration and postoperative stroke. ⋯ This series suggests that epsilon-aminocaproic acid administration does not increase the risk of postoperative stroke.

Inversion of the left atrial appendage can masquerade as a new left atrial mass. Failure to be aware of this entity can result in unnecessary diagnostic and therapeutic procedures. If the entity is diagnosed intraoperatively, treatment is simple with external reduction and ligation.

Although some pediatric cardiology departments have a policy of adopting primary correction of tetralogy of Fallot in all symptomatic infants, we and others still palliate neonates and infants. Effective palliation should ameliorate symptoms and allow growth of the pulmonary arteries. Although studies on the growth of the ipsilateral and contralateral pulmonary arteries after a classic Blalock-Taussig shunt have been reported, pulmonary artery growth after a modified Blalock-Taussig shunt has not been studied as thoroughly. Therefore, we examined whether there is equal growth of the contralateral pulmonary artery after a modified Blalock-Taussig shunt. ⋯ We showed equal growth of the right and left pulmonary arteries with no distortion after a modified Blalock-Taussig shunt. If palliation is considered, the modified Blalock-Taussig shunt remains our choice.

Two patients with an inverted left atrial appendage after cardiac surgery were presented. Magnetic resonance imaging is one of the useful methods to establish an accurate diagnosis of this complication. In 1 patient, it repaired spontaneously without surgical intervention.

Cerebral protection by lidocaine during cardiac operations.
Lidocaine improves outcome in animal brain injury models. Cardiac operations often cause postoperative neuropsychological (NP) impairment. We investigated cerebral protection by lidocaine in cardiac surgical patients. ⋯ These data show that cerebral protection by lidocaine, which is unrelated to any effect on depression or anxiety, and is at a level that is noticed by the patients.
