Phrenic nerve injury has been reported with the use of iced slush for topical cardiac hypothermia. A review of the preoperative and the postoperative chest roentgenograms was performed to detect phrenic nerve injury in patients undergoing cardiac operation with the use of iced slush for topical hypothermia from January, 1985 to June, 1987. The reviewed series included 45 patients who had undergone valve replacement. In this review, the injured site of phrenic nerve was left in 13 cases, right in 1 case and the overall incidence of phrenic nerve paralysis following open heart surgery was 31%. Compared to the incidence of phrenic nerve paralysis in the control group [without pericardial insulation] [406, 12 cases/30 cases], that in the group of patients receiving pericardial insulation [13.3%, 2 cases/15 cases] was lower, but there was no statistical significance. The initial time that diaphragmatic paralysis developed was mean 3.5 days [range 1-8 days] postoperatively and the recovery time of the paralysis was mean 4.7 months [range 0.5-10.5 months] postoperatively.

We had studied 20 cases of VSD patients whose murmur was sustained after open heart surgery from 1977 to 1984. The postoperative cardiac catheterization was performed on post-op. 20th day. Their ages ranged from 5 to 25 years old. Among them, 4 patients had significant residual shunt which required reoperation. [1 patient; re-op, 3 patient; refused]. Sex ratio was 13:7 in male and female. Associated anomalies were PDA, ASD, Pulmonary stenosis, Mitral insufficiency. Except 1 case, all of them was Kirklin type II VSD. Postoperative complications were I RBBB, residual shunt, cardiac tamponade due to bleeding, wound infection. Preoperative pulmonary artery systolic pressure was highly related to residual shunt in our study. Postoperative LVEDV returned to normal range on the 3rd week.

Autologous blood transfusion is a common method of reducing the need for homologous blood transfusion during cardiac operations. Between June 1991 and May 1992, 12 cases [Group I] were experienced autologous blood transfusion using Cell Saver undergoing double valve replacement or redo-valve replacement. Control group [N=12, Group II] was selected to above similar operation during same period. The Cell Saver system [Haemonetics Corp.] was employed for autologous blood transfusion. The blood shed in the operative field before and after cardiopulmonary bypass and remained cardiotomy reservior was aspirated by means of a locally heparinized collecting system. After centrifused salvaged blood, the resulting red cell concentrate reinfused subsequently. The patient receiving autologous blood transfusion required significantly less homologous blood transfusion than their control group. [Group I; 3519 $\pm$ 869, Group II; 4622 $\pm$ 856, Respectively; P=0.005] There were no clinical infections in the autotransfusion group. And there was no apparent intergroup difference of the clinical findings, hematologio datas and coagulation parameters. We conclude the autotransfusion using Cell Saver is effective for reducing of the hom-ologlous blood transfusion in cardiac surgery.

The cardiac anatomic position immediately beneath the sternum leaves it vulnerable to injury when this bone is fractured. Cardiac rupture, however, is uncommon but survival following this injury is rare. We report the case of one patient who survived right ventricle perforation resulting from sternal fracture. The patient developed signs of pericardial tamponade and was brought to the operating theatre immediately for surgery through the emergency anterolateral thoracotomy Perforation of th right ventricle was repaired by direct closure without cardiopulmonary bypass. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and surgery.

Coronary sinus ostial atresia (CSOA) with persistent left superior vena cava (LSVC) in the absence of an unroofed coronary sinus is a benign and rare anomaly that may be taken lightly in most instances. However, if overlooked in patients undergoing univentricular heart repair such as bidirectional Glenn or Fontan-type surgery, fatal surgical outcomes may occur due to coronary venous drainage failure. We report a case of CSOA with a persistent LSVC that was managed through coronary sinus rerouting during a total cavopulmonary connection, and provide a review of the literature regarding this rare anomaly.

Between March, 1989, and August, 1993, 10 patients underwent aortocoronary bypass surgery concomittant with cardiac valve replacement. They were 6 men and 4 women, the age ranging from 47 to 64. 7 patients underwent single valve replacement and 2 patients underwent double valve replacement, Another one patient underwent only CABG one year after valve replacement and he had no evidence of prosthetic valve failure. Total number of graft vessels were.15,14 were saphenous venous grafts and 1 was internal mammary artery graft. Dyspnea on exertion was frequent symptom and was found in all patients. 8 patients presented stable angina, only 1 patient presented postinfarct angina and another 1 patient presented no angina symptom. The graft was placed prior to valve replacement and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout operation. Postoperative course was uneventful and there was no hospital mortality, as was supported by many reports, it is our opinion that simultaneous valve replacement and aortotomy bypass graft does not increase the risk of cardiac valve replacement substantially.

We defined factors affecting the postoperative outcome in adult cardiac surgery with cardiopulmonary bypass (CPB). Thirty-two adult patients scheduled for elective cardiac surgery participated in this study. Levels of leukocyte, glutamic oxaloacetic transaminase (GOT), troponin-I (cTNI), interleukin-6 (IL-6), D-dimer and neuron-specific enolase (NSE) were significantly elevated, whereas platelet count declined in cardiac surgery with CPB. GOT and D-dimer levels at CPB-off each had a positive significant correlation significantly with 24 hrs-bleeding, total bleeding, mechanical ventilatory assist time, ICU stay time and length of hospitalization. BUN levels at CPB-off were directly related to total bleeding, mechanical ventilatory assist time, ICU stay time and length of hospitalization. Platelet count at CPB-off was inversely related to mechanical ventilatory assist time, ICU stay time and length of hospitalization. Creatinine concentration at CPB-off interrelated positively with mechanical ventilatory assist time and ICU stay time. NSE levels at CPB-off had a positive relationship with postoperative 24 hrs-bleeding. The length of hospitalization was prolonged proportionally to the elevation of cTNI levels in cardiac surgery. Aortic cross-clamping and total CPB times also related with increase of 24 hrs and total bleeding volumes and the length of hospitalization. IL-6 and ET-1 had no mutual relation with any postoperative outcome. These data suggest that GOT, BUN, creatinine, D-dimer and platelet levels are the most important factors affecting postoperative outcomes and patient's recovery in adult cardiac surgery with CPB.

Aprotinin, a serine protease inhibitor, has been used to ameliorate the inevitable consequences, including blood component injury after cardiac surgery with cardiopulmonary bypass (CPB). However, there are many arguments on its dosage or usage. We assessed whether administration of low dose of aprotinin in only priming solution has any beneficial effect or reduces its side effects on cardiac surgery. Thirty patients scheduled for elective cardiac surgery were randomly assigned to aprotinin group (n=15) which received aprotinin in priming solution (two million kallikrein inhibitory unit, KIU) and added one million KIU at 1 hour after the beginning of CPB or control group (n=15) which did not receive it. Hematological and biochemical variables, cytokines and cardiac marker levels, and postoperative outcomes were compared between two groups at before, during or after operation. Platelet count in aprotinin group was higher than that of control group at postoperative 24 hr. Activated partial thromboplastin time in aprotinin group was longer than that of control group at intensive care unit (ICU). Troponin-I level and postoperative blood loss volumes in aprotinin group were lower than those of control group at ICU. There were no significant differences between the two groups on the others. These results showed that low dosage of only priming solution during cardiac surgery with CPB reduced platelet destruction and postoperative bleeding, and attenuates myocardial damage. However, further studies need to be carried out with more population or pediatric patients for evaluating various aprotinin usage.
