Intraoperative surgical sealant application during cardiac defect repair

Bleeding can occur as a sequela to cardiac surgery. Surgical products-such as conventional sutures and clips, and somewhat less conventional sealants-have been developed to prevent this event. Among these, CoSeal is a sealant used at our institution; here we report the cases of 2 patients in whom CoSeal was used successfully as either a supplement or an alternative to suture repair. This sealant was found to be useful in attaining hemostasis both in high-pressure ventricular repair and in the rupture of a friable coronary sinus adjacent to vital structures (in this instance, a left circumflex coronary artery).
