  • Early repair of complex congenital heart malformation may lead to life-threatening respiratory and hemodynamic embarrassment on sternal closure. We performed delayed sternal closure in nine neonates to avoid a fatal outcome in these situations. Primary elective open sternum was used in 8 [66.7% and primary sternal closure in 4 [33.3% of the 12 patients studied. one patient with primary sternal closure underwent delayed sternal reopening in the intensive care unit. Of the 9 patients with open sternum, 2 patients died of low cardiac output and acute renal failure respectively before delayed sternal closure. 7 patients could undergo delayed sternal closures 3 days after initial operation. The mean age at open cardiac procedure was 14.3 days [range 3 to 30 and mean preoperative weight was 3.4kg [range 2.8 to 4.1 . The aortic cross-clamping time was longer in the group with open sternum than the group with closed sternum [p=0.042 . There was no morbidity and mortality related to delayed sternal closure. Given the low morbidity and potential benifits, this technique should be used in neonates after open heart procedures when postoperative mediastinal compression produces frank low cardiac output or respiratoy compromise during a trial of sternal closure.

  • The records of 248 patients over 16 years of age who had undergone a surgical correction of a congenital cardiovascular malformation during the period of 10 years from August, 1978 to July, 1988 were reviewed. During this period, the incidence of congenital cardiovascular malformation in adult was 18.2% of 1376 total heart disease operated on and 25.5% of 986 congenital heart defects. Among them, there were 200 patients in acyanotic group and 48 patients in cyanotic group. Male versus female ratio was 1:1.28. The oldest patient was 59 years old female who had atrial septal defect. The mean age was 24.4 years old. The distribution of the lesions showed a large preponderance of atrial septal defects [37.19o] followed in frequency by ventricular septal defects [918.1%], patent ductus arteriosus [17.3%], tetralogy of Fallot [16.1%], and a variety of other complex malformations[3.2%]. In the pediatric age group, relative frequency was different from that of this adult group, showing ventricular septal defects, tetralogy of Fallot, patent ductus arteriosus and atrial septal defects in order of incidence. The hospital mortality and late mortality were 6.0% and 1.7% respectively. The causes of hospital death were low cardiac output in 10 patients, arrhythmia in 2, air embolism in 1, sepsis in 1 and respiratory failure in l. Clinical improvement upto NYHA functional class I or II postoperatively has been achieved and sustained in all patients following repair except the patients of late death and receiving reoperation. This result confirms that congenital heart defects in the adults can be corrected with a good outcome and an aggressive operative approach seems justified.

  • Berry syndrome (interrupted aortic arch, aortopulmonary window, and aortic origin of right pulmonary artery with intact interventricular septum) is a very rare and complex cardiac malformation. We report a successful one-stage repair in a 14-day-old neonate without circulatory arrest.

  • This report describes the echocardiographic features of an indirect Gerbode defect in a young cat. Echocardiography revealed high-velocity, turbulent systolic flow directed from left ventricle to right ventricle through a ventricular septal defect. The flow immediately entered the right atrium through a tricuspid septal leaflet. The indirect-type Gerbode defect was confirmed through necropsy. When a high-velocity turbulent flow in the RA without pulmonary hypertension is observed on echocardiography, Gerbode defect should be considered.

  • Berry syndrome (a distal aortopulmonary window and a right pulmonary artery originating from the ascending aorta, an intact ventricular septum, a patent ductus arteriosus and an interrupted aortic arch) is a rare complex congenital cardiac malformation. We describe a case of one stage repair with using an autologous arterial flap in a 19-day-old neonate who was suffering with this malformation, and we report on the development of postoperative right pulmonary artery stenosis and its successful management with performing multiple balloon angioplasties.

  • In this study, the potential toxicity of isoprocarb was demonstrated using zebrafish embryos. We treated isoprocarb (0, 29, and 58 mg/L) to the zebrafish embryos for 72 h then, we estimated morphological changes and apoptotic cell numbers. The increasing extent of apoptosis from the anterior to posterior region of developing zebrafish larvae was correlated with toxicity in the overall development process, including growth and normal organ formation. The appearance of abnormalities in the isoprocarb-treated groups in comparison to normal developing zebrafish larvae was verified using quantitative image analysis based on ImageJ software program. The vascular system comprising a complex interconnection of blood vessels was visualized in vessel-fluorescent transgenic zebrafish (fli1:eGFP). The main vasculature was malformed on isoprocarb treatment, and this was also related to cardiac defects. Taken together, normal embryonic development in zebrafish was interrupted owing to the acute toxicity of isoprocarb.

  • Ebstein's anomaly is a complex malformation that can be treated by various surgical techniques, either repair or replacement of the abnormal tricuspid valve, with variable results. The essence of the malformation is the downward displacement of the septal and posterior leaflets into the ventricle, resulting in the formation of an atrialized portion of the right ventricle. The aim of surgical repair is to correct the tricuspid valve dysfunction and to plicate the atrialized portion of the right ventricle A 12-months old female was admitted with the diagnosis of Carpentier type A of Ebstein's anomaly with severe tricuspid regurgitation. She successfully underwent operation with vertical plication of right ventricle and reimplantation of tricuspid leaflets. Postoperatively cardiac size was significantly reduced and tricuspid regurgitation was trivial in echocardiography. She was diacharged the 14th postoperative day.
