Background/aim: Penetrating heart injuries result in high mortality. We designed a new catheter to facilitate the treatment of penetrating
cardiac injuries and provide more effective initial bleeding control and fluid replacement.
Materials and methods: The cardiac injury model was applied to 8 female 1-year-old Sus domesticus pigs. Subjects were grouped
according to whether a Foley catheter or a newly designed catheter was placed into the heart through cardiac lacerations. Changes in
systolic blood pressures, mortality, and problems encountered during surgery and other intraoperative findings were recorded.
Results: There were higher mean blood pressure measurements in the newly designed catheter group during stages IV to VII. All
subjects had tamponade and cardiac activity after completion of the repair of all lacerations in the catheter group, whereas in the other
group only one subject did. Intraoperative direct fluid infusion to the heart through the catheters in the diastole was performed in all
subjects of both groups. However, regurgitation from the cardiac cavity in the systole was seen only in the Foley catheter group. All of
the intraoperative complications were seen in the same group.
Conclusion: The newly designed catheter can provide effective initial bleeding control, better initial vital sign stabilization, and fewer
intraoperative problems during primary repair of cardiac lacerations.
