Even though some authors have reported on the advantages of early total correction of complex heart disease, for low birth weight premature neonates, most surgeons prefer a multi-step approach to early total correction due to the many problems, such as the technical problems, the cardiopulmonary bypass management and etc. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,250 gram premature neonate.

Recently, surgical outcomes of repair of tetralogy of Fallot (TOF) have improved. For patients with TOF older than 3 months, primary repair has been advocated regardless of symptoms. However, a surgical approach to symptomatic TOF in neonates or very young infants remains elusive. Traditionally, there have been two surgical options for these patients: primary repair versus an initial aortopulmonary shunt followed by repair. Early primary repair provides several advantages, including avoidance of shunt-related complications, early relief of hypoxia, promotion of normal lung development, avoidance of ventricular hypertrophy and fibrosis, and psychological comfort to the family. Because of advances in cardiopulmonary bypass techniques and accumulated experience in neonatal cardiac surgery, primary repair in neonates with TOF has been performed with excellent early outcomes (early mortality<5%), which may be superior to the outcomes of aortopulmonary shunting. A remaining question regarding surgical options is whether shunts can preserve the pulmonary valve annulus for TOF neonates with pulmonary stenosis. Symptomatic neonates and older infants have different anatomies of right ventricular outflow tract (RVOT) obstructions, which in neonates are nearly always caused by a hypoplastic pulmonary valve annulus instead of infundibular obstruction. Therefore, a shunt is less likely to preserve the pulmonary valve annulus than is primary repair. Primary repair of TOF can be performed safely in most symptomatic neonates. Patients who have had primary repair should be closely followed up to evaluate the RVOT pathology and right ventricular function.

BACKGROUND: Despite the excellent early results after the repair of congenital bicuspid aortic valve (BAV) disease, the mid-term durability of the repaired valve has still controversies. MATERIAL AND METHOD: To evaluate the mid-term results of BAV repair, retrospective review of medical records and echocardiographic data were done. Between 1994 and 2003, twenty-two patients underwent reparative procedure for either regurgitant or stenotic congenital bicuspid aortic valve (BAV). RESULT: Mean age was 41+/-14 years with male predominance (Male=17, Female=5). The pathophysiologies of the BAV were regurgitation-dominant in 20 (91%) and stenosis-dominant in 2 (9%) cases. Various repair techniques were used for raphe, prolapsed leaflet, thickened leaflet, and commissures; 1) release of raphe in 19 (86%), 2) wedge resection and primary repair in 11 (50%), pericardial patch reinforcement after plication of the leaflet in 6 (27%), and plication of the leaflet in 3 (14%), 3) slicing of thickened leaflet was used in 12 (55%) cases, 4) commissuroplasty in 8 (36%), and commissurotomy in 6 (27%) cases. There was no in-hospital mortality. During the mean follow-up of 38+/-17 months, one patient underwent aortic valve replacement after developing acute severe regurgitation from dehiscence of the suture on postoperative 2 months. New York Heart Association functional class was improved from 1.9+/-0.6 to 1.2+/-0.5 (p<0.01). Left ventricular end-systolic and diastolic dimension (LVESD/LVEDD) were also improved from 45+/-9 and 67+/-10 to 37+/-10 and 56+/-10, respectively (p<0.01). The grade of aortic regurgitation (AR) was improved from preoperative (3.1+/-1.2) to post-bypass (0.9+/-0.7). However, the grade at last follow-up (1.7+/-1.1) was deteriorated during the follow-up period (p<0.01). Freedom from grade III and more AR at one, three, and four year were 89.7%, 89.7%, and 39.9% respectively. CONCLUSION: Midterm clinical result of the BAV repair was favorable. But, the durability of the repaired valve was not satisfactory.

OBJECTIVES: The aim of this study is to evaluate the short-term results and complications of treating the intertrochanteric fracture with bipolar hemiarthroplasty (BHA) in elderly population. METHODS: We retrospectively reviewed 31 unstable intertrochanteric fracture patients who were treated with BHA between January 2007 and August 2009 in older populations more than 65 years old. The 6 males and 25 females had a mean age of 79.8 years (range: 66-88) and a mean follow-up of 36.3 months (range: 24-55). We analyzed the radiological outcomes, functional recovery grade, using Jensen's social function score and Harris hip score (HHS), and complications. RESULTS: The average operation time and blood loss was 148.9 min (range, 110-215 min) and 455.2 mL (range, 200-1200 mL). Mean preoperative and postoperative hemoglobin (Hb) was 10.9 g/dL (range, 8.6-13.4 g/dL) and 10.5 g/dL (range, 5.1-14.1 g/dL) respectively. Average 1.3 pints of blood transfusion was performed. Ambulation with (or without) crutch was possible at mean 6.8 days postoperatively. The stability and alignment indices were adequate in all cases at final follow-up. On clinical results, the average HHS score, was changed from 79.7 points (range, 44-100) preoperatively to 73.0 points (range, 46-92) postoperatively, and the preoperative and postoperative Jensen's score was 1.8 (range, 1-3) and 2.1 (range, 1-4) respectively. CONCLUSIONS: The BHA is an acceptable alternative for unstable intertrochanteric fractures in older population.

5.Indentation in the Right Ventricle by an Incomplete Pericardium on 3-Dimensional Reconstructed Computed Tomography.
The Korean Journal of Thoracic and Cardiovascular Surgery 2017;50(4):298-299
We report the case of a 17-year-old girl who presented with an indentation in the right ventricle caused by an incomplete pericardium on preoperative 3-dimensional reconstructed computed tomography. She was to undergo surgery for a partial atrioventricular septal defect and secundum atrial septal defect. Preoperative electrocardiography revealed occasional premature ventricular beats. We found the absence of the left side of the pericardium intraoperatively, and this absence caused strangulation of the diaphragmatic surface of the right ventricle. After correcting the lesion, the patient’s rhythm disturbances improved.

Ebstein's anomaly is a complex congenital defect of the tricuspid valve and right ventricle. Various surgical methods to repair the regurgitant tricuspid valve have been reported, and most of them depend on monocuspidalization with using the anterior leaflet. We report here on our first experience with Ebstein's anomaly in a 31-year-old female patient who underwent cone reconstruction of the tricuspid valve with using three leaflets.

Journal of Chest Surgery 2024;57(3):231-239
Background:
Although the modified Blalock-Taussig shunt remains the mainstay method of palliation for augmenting pulmonary blood flow in various congenital heart diseases, the shunt must be carefully designed to achieve the best outcomes. This study investigated the effect of shunt configuration on pulmonary artery growth and growth discrepancy.
Methods:
Twenty patients with successful modified Blalock-Taussig shunt takedown were analyzed. Pulmonary artery and shunt characteristics were obtained using computed tomography scans. Differences in the baseline and follow-up diameter ratios and growth in the ipsilateral and contralateral arteries were calculated. The angle between the shunt and pulmonary artery, as well as the distance from the main pulmonary artery bifurcation, were measured. Correlations between pulmonary arteries and shunt configurations were analyzed.
Results:
The median interval time between shunt placement and takedown was 154.5 days (interquartile range, 113.25–276.25 days). Follow-up values of the ipsilateral-to-contralateral pulmonary artery diameter ratio showed no significant correlation with the shunt angle (ρ=0.429, p=0.126) or distance (ρ=0.110, p=0.645). The shunt angle and distance from the main pulmonary bifurcation showed no significant correlation (ρ=-0.373, p=0.189). Pulmonary artery growth was negatively correlated with shunt angle (ipsilateral, ρ=-0.565 and p=0.035; contralateral, ρ=-0.578 and p=0.030), but not with distance (ipsilateral, ρ=-0.065 and p=0.786; contralateral, ρ=-0.130 and p=0.586).
Conclusion
Shunt configuration had no significant effect on growth imbalance. The angle and distance of the shunt showed no significant correlation with each other. A more vertical shunt was associated with significant pulmonary artery growth. We suggest a more vertical graft design for improved pulmonary artery growth.
