  • Two patients with uncorrectable cyanotic cardiac anomalies underwent total cavopulmonary shunt[modified Fontan operation]. Case I was a 14 years old male with dyspnea and cyanosis after birth. Aortogram showed TGA combined with overriding of aorta, pulmonary stenosis, complete atrioventricular septal defect, interruption of inferior vena cava, and situs inversus totalis. We had performed total cavopulmonary shunt using with 16 mm Gortex Graft in single atrium to bypass the hepatic vein to pulmonary artery. Postoperatively, patient sustained low PaCO2 and low cardiac output and then expired at 19th postoperative day. The cause of death of the patient would be low cardiac output. Case II was a 6 years old female with dyspnea and cyanosis after birth. Aortogram showed tricuspid atresia[Type IIb], transposition of great arteries, atrial septal defect, ventricular septal defect and pulmonary stenosis, We had performed total cavo-pulmonary shunt using intraatrial baffle[tunnel] with Goretex patch. The postoperative course of this patient was good without event.

  • Doxorubicin and daunorubicin are excellent chemotherapeutic agents utilized for several types of cancer but the irreversible cardiac damage is the major limitation for its use. The biochemical mechanisms of doxorubicin- and daunorubicin- induced cardiotoxicity remain unclear. There are many reports on toxicity of doxorubicin and doxorubicin in cardiomyocytes, but effects in cardiovascular system by these drugs are almost not reported. In this study, we investigated gene expression profiles in human umbilical vein endothelial cells (HUVECs) to better understand the causes of doxorubicin and doxorubicininduced cardiovascular toxicity and to identify differentially expressed genes (DEGs). Through the clustering analysis of gene expression profiles, we identified 124 up-regulated common genes and 298 down-regulated common genes changed by more than 1.5-fold by all two cardiac toxicants. HUVECs responded to doxorubicin and doxorubicin damage by increasing levels of apoptosis, oxidative stress, EGF and lipid metabolism related genes. By clustering analysis, we identified some genes as potential markers on apoptosis effects of doxorubicin and doxorubicin. Six genes of these, BBC3, APLP1, FAS, TP53INP, BIRC5 and DAPK were the most significantly affected by doxorubicin and doxorubicin. Thus, this study suggests that these differentially expressed genes may play an important role in the cardiovascular toxic effects and have significant potential as novel biomarkers to doxorubicin and doxorubicin exposure.

  • Background: Despite recent advances in surgical technique and perioperative care of total anomalous pulmonary venous return (TAPVR), post-repair pulmonary vein stenosis (PVS) remains as a serious complication. We thought that the most important factors of TAPVR repair to prevent PVS were good exposure, proper alignment, and sufficient stoma size. We analyzed our experience retrospectively. Material and Method: Between Jan. 1995 and Feb. 2005, we studied 74 patients diagnosed with TAPVR suitable for biventricular repair. Supra-cardiac type (n=41, 55.4%) was the most common. Mean CPB time, ACC time, and TCA (40.5%, 30/74) time were $92.1{\pm}25.9\;min,\;39.1{\pm}10.6\;min$, and $30.2{\pm}10.7\;min$, respectively. Mean follow-up duration was $41.4{\pm}29.1$ months and follow-up was possible in all patients. Result: The median age and body weight at operation were 28.5 days ($0{\sim}478$ days) and 3.4 kg $(1.4{\sim}9\;kg)$. Early mortality was 4.1% (3/74). Causes of death were pulmonary hypertensive crisis, sepsis, and sudden death. There was PR-PVS in 2 patients (early: 1, late: 1). Both patients were cardiac type TAPVR drained to coronary sinus. Re-operations were done but only one patient survived. Cumulative survival rate in 5 year and percent freedom from PVS were $94.5{\pm}2.7%\;and\;97.2{\pm}2.0%$, respectively. Conclusion: There was no PVS in patients who underwent extra-cardiac anatomosis between LA and CPVC. Therefore it could be said that our principle might be effective in preventing PR-PVS in patients suitable two-ventricle.

  • Background: Subclavian vein (SV) catheterization is a method for the delivery of fluids, drugs, and blood products, venous blood sampling, and central vein pressure monitoring in cardiac surgery. Catheter occlusion is a serious complication of SV catheterization during cardiac surgery, especially after sternal retractor expansion. Methods: In this observational study, 303 patients who had successful right infraclavicular SV catheterization from September 2019 to April 2020 were enrolled to determine the incidence of catheter occlusion. After catheterization, the lumens of all catheters were checked for the ability to infuse and withdraw blood from the catheter before and after sternal retractor expansion. The patients' characteristics, cannulation approach, on-pump or off-pump technique, occlusion of the catheter and its lumens, and any associated complications were recorded. The data were analyzed using IBM SPSS ver. 22.0 (IBM Corp., Armonk, NY, USA). Results: Of the 303 patients studied, 205 were male (67.7%) and 98 were female (32.3%). Catheter occlusion occurred in 11 patients with on-pump cardiopulmonary bypass (CPB) (227 patients) and 4 patients with off-pump CPB (76 patients) (p=0.863). The incidence of catheter occlusion was 4.95% (15 of 303 patients) with no cases of simultaneous 3-lumen occlusion in a catheter. The most commonly occluded lumen was the distal lumen (57.92%). Simultaneous 2-lumen occlusion occurred in 4 patients. Catheter occlusion was found in 3 of 13 malpositioned catheters (23.07%). Conclusion: The current study showed that malpositioning of the catheter tip was a risk factor for catheter occlusion and that the distal lumen of a triple-lumen catheter was the most commonly occluded lumen.

  • Primary masses rarely originate from the heart and great vessels, and a malignant peripheral nerve sheath tumor (MPNST) is extremely rare. A 76-year-old male with pleural effusion underwent contrast-enhanced computed tomography, which revealed a hypoattenuating mass involving the right pulmonary vein and left atrium. Ultrasonography showed that the mass originated from the right pulmonary vein. Surgical resection confirmed an MPNST that originated from the pulmonary vein. We report the first Korean case of a primary MPNST originating from the pulmonary vein. We have also described the radiologic findings suggestive of a pulmonary vein mass.

  • This study was conducted to determine the effects of deep breathing exercise and ankle exercise on blood flow velocity in the femoral vein. Sixteen healthy male students were recruited from Yonsei University, at Wonju. The blood flow velocities in the femoral vein were measured under three different conditions: resting, deep breathing, and ankle exercise. All subjects were given a 5-minute relaxing time in supine position prior to the study. Using a doppler ultrasound with a 8 MHz probe, the peak blood flow velocities were collected in a twenty-second-period at each condition. The subjects took a rest in between trials for the blood flow to return to its resting levels. The result showed a significant difference in peak blood flow velocities under those three conditions (p<.001). The peak blood flow velocity was highest in ankle exercise condition. The peak blood velocity was significantly higher in deep breathing condition compared with the resting condition. As a result, it is revealed that not only the muscular contractions but also the deep breathing exercises induced facilitating effects of venous return. Either of the exercise methods can be recommended to prevent blood stasis in patients with risk of deep vein thrombosis after cardiac or lower extremity surgery.

  • We experienced the seven cases of penetrating and non-penetrating cardiac injuries combined with cardiac tamponade from June 1986 to June 1989 at Seoul and Chun-An Hospital of SOONCHUNHYANG medical college. The results were as follows. l. In sex distribution, 7 cases were male. In age distribution, The fourth decades occupied about 58 % of all cases. 2. In mode of injury, 4 cases were stab wounds, 1 case penetration by metallic fragment, 2 cases blunt chest trauma. 3. We routinely checked the CVP with subclavian vein catheterization in case of suspicious cardiac tamponade. Significant increments were showed in 4 cases. 4. Becks triad [low blood pressure, raised central venous pressure, distant heart sound] were recorded in 43 % of the cases with proven tamponades. 5. The sites of injury included RV in 4 cases, LV in 1 case, RA in 1 case and branch of RCA in 1 case. The RV injuries were the most common. 6. Coronary artery damage occurred in 2 cases. LADA was severed in 1 case combined with RV rupture and branch of RCA was torn 1 case. 7. Pericardiocentesis was performed 1 case at another hospital before referring to our hospital. We have never used the procedure because we think that it is potentially dangerous with no clear benefit. 8. Subxyphoid pericardial window was performed in 2 cases of severe cardiac tamponade. We have employed this method to stabilize the patients who had systolic hypotension. 9. Surgical approaches were performed with median sternotomy in 3 cases, thoracotomy in 4 cases. 10. We undertook the simple closure in 6 penetrating cardiac wounds. The removal of impacted metallic fragment was performed under the cardiopulmonary bypass. Simple ligation was performed in 2 cases of coronary artery severance 11. One patient with no sign of life was urgently intubated and undertaken an emergency room thoracotomy on the stretch car without antiseptic preparation. The cardiorrhaphy in 6 cases were performed in the operating theater 12. One patient undertaken emergency room thoracotomy did not survive due to refractory hypovolemic shock. But the remaining 6 patients recovered.

  • From Nov. 1987 to Aug. 1989, 12 patients with coronary occlusive disease underwent coronary bypass surgery at the Department of Thoracic and Cardiovascular Surgery, Catholic University Medical College. The results were as follows: 1. There were 9 males and 3 females ranged in age from 25 to 69 years with a mean of 50.4 years. 2. The prevalent locations of coronary artery stenosis were left anterior descending branch [9 cases], right coronary artery[4 cases], first diagonal branch[3 cases], left circumflex artery [2 cases] in order of frequency. 3, Among 12 cases, 5 cases had an episode of previous myocardial infarction respectively. 4. We performed triple bypass operation in 3 cases, double bypass in 2 cases and single bypass in 7 cases using great saphenous vein. 5. Postoperative complications were cerebral embolism[1, died], pleural effusion[1], temporary cardiac arrest[1], supraventricular tachycardia[1] and late gastric ulcer bleeding[1]. 6. The follow up periods were ranged from 8 months to 30 months and all survivors were on antiplatelet medication showing free of angina.

  • From February 1986 through September 1986, the authors have experienced 6 cases of coronary artery bypass graft for patients with unstable angina. There were five males and one female who ranged from 39 to 65 years [mean, 53.3 years]. The extent of coronary disease was as follows: one-, two- and three-vessel diseases, all 2 cases respectively, and among them, 1 case had left main disease. Distal anastomoses were performed first with using saphenous vein grafts as conduits in all cases and sequential bypass methods were employed in 5 cases. Numbers of vein grafts were two in 2 cases and one in 4 cases. The mean time wasted for one distal anastomosis was 36 minutes. Post operative complications were leg-wound disruption [2 cases], transient psychosis [1 case] and perioperative myocardial infarction [MI] [1 case]. Sixty three year-old male patient associated with cardiomegaly, prior MI, ventricular arrhythmia, cardiac dysfunction and endocrinologic diseases preoperatively was expired in the operating room due to perioperative Ml. All survivors were asymptomatic and on discontinuing medical therapy on follow-up varying from 1 to 8 months.

  • The juxtaposition of atrial appendage may possibly be diagnosed by angiography recently, and it is widely regarded as an ominous sign of severe cyanotic congenital heart disease. However, it is apparently rare congenital cardiac anomaly in which the atrial appendages lie side by side, both to the left or right of the great arteries, known as left or right juxtaposition of the atrial appendages. Juxtaposition of the atrial appendages has no functional significance, since it does not, itself, cause any hemodynamic disturbance. But it`s presence always indicates the coexistence of other major cardiac anomalies. In review of literatures TGA and VSD are invariable present, and ASD is common. Other anomalies, such as, tricuspid atresia, pulmonary outflow that, obstruction bicuspid pulmonic valve, persistent SVC etc. are relatively high incidence. In this report, we present one case of 6 year old female child having left juxtaposition of atrial appendage combined with TGA [D-looping, D-transposition], TAPVD, large ASD, small VSD, and vertical vein.
