  • Congenital diverticula of the cardiac ventricle have been reported as arising either from the left ventricle or, rarely from both ventricles. A diverticulum arising from the right ventricle alone is very rare. Furthermore the diverticulum associated with double chambered right ventricle was extremely rare. We experienced a 62 years old female of double chambered right ventricle combined with congenital right ventricular true diverticulum. She had complained intermittent chest pain and mild dyspnea on exertion during 8 months. The chest X-ray and chest CT showed protruded abnormal density at anterolateral side of right ventricular outflow tract. Preoperative angiography demonstrated a double chambered right ventricle and a right ventricular diverticulum. In operative finding, there was found a anomalous muscle band, dividing the right ventricle into an inflow and outflow portion, and a 5x6cm sized right ventricular diverticulum arised from conus region with a stenotic orifice of 1.5cm in diameter. The diverticulum was open toward the infundibulum, and its orifice was approximately 1cm in diameter. On treatment, the diverticulum orifice was closed directly and the abnormal muscle band was resected in order to widen the right ventricular outflow tract. The postoperative result was satisfactory and good without specific complications.

  • This is one case report of the extremely rare congenital cardiac malformation, Double-outlet of left ventricle in corrected transposition of great arteries. 11-year-old boy complained acrocyanosis and exertional dyspnea, the parents noticed cyanosis since birth. Physical examination revealed acrocyanosis, clubbed fingers and toes, G-III pansystolic murmur on 2nd and 3rd ICS, LSB. Right heart catheterization revealed significant $O_2$ jump in ventricular level. Right and left ventriculography showed the both catheters arriving in the same ventricle i.e. anterior chamber, morphological left ventricle was in right and anterior position, simultaneous visualization of aorta and pulmonary artery and aorta locating anterior and right side of pulmonary artery. Echo cardiogram surely disclosed interventricular septum. Conclusively it was clarified that the patient has Double-outlet of left ventricle and corrected transposition of great arteries [S.L.D.]. Operation was performed to correct the anomalies under extracorporeal circulation with intermittent moderate hypothermia. Right-sided ventriculotomy disclosed the following findings. 1. Right-sided ventricle was morphological left ventricle. 2. Left-sided ventricle was morphological right ventricle. 3. Right side atrioventricular valve was bicuspid. 4. Left side atrioventricular valve was tricuspid. 5. Aortic valve was superior, anterior and right side of pulmonary valve. 6. Subpulmonary membranous stenosis. 7. Non-committed ventricular septal defect. We made a tunnel between VSD and aorta with Teflon patch so that arterial blood comes through VSD and the tunnel into aorta. After correction the patient needed assisted circulation for 135 min. to have adequate blood pressure. Postoperatively by any means, adequate blood pressure could not be maintained and expired in the evening of operation day.

  • The myocardial temperature was monitored in 19 patients of open heart surgery using the Shiley myocardial temperature probe in Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The myocardial temperature were measured time-wise: initial and 15 minutes following the infusion of the cardioplegic solution into the aortic root and upon reinfusion, which is 30 minutes apart from the initial. The measurements were made in the anterior wall of the right ventricle, the posterior wall of the left ventricle and the interventricular septum. Immediately after initial infusion, the temperature of the right ventricle[10.7 $\pm$4.3oC] was the lowest and that of the left ventricle[12.9$\pm$3.9 oC] the highest in the mean values among all 19 patients. However, no significant differences were noted among the different regions. At 15 minutes after infusion, the lowest temperature was in the right ventricle[17.5$\pm$5.1 oC], followed by interventricular septum[17.9$\pm$2.9 oC], and left ventricle[21.4$\pm$2.5 oC]. At 30 minutes after infusion, the lowest temperature was measured in the interventricular septum[13.6$\pm$2.7 oC ], followed by right ventricle[13.8$\pm$4.0 oC] and left ventricle[14.5$\pm$4.5 oC ]. Evaluating changes of myocardial temperature according to postinfusion time, the temperature at 15 minutes after infusion showed significant increase as compared with that immediately after the infusion in all three regions[p<0.05] and the temperature at 30 minutes after infusion showed significant decrease as compared with that at 15 minutes after the infusion in the left ventricle and the interventricular septum[p<0.05]. The left ventricle was rewarmed most rapidly and its temperature the highest in the mean values, Accordingly, the maintenance of optimal hypothermia of the left ventricle indicated a very careful factor in myocardial protection.

  • The division of the right ventricle into two chambers by aberrant muscle bands traversing the sinus portion, Double Chambered Right Ventricle[DCRV], is a relatively rare congenital cardiac malformation. Double Outlet Right Ventricle[DORV], basically recognized by the origin of both great arteries from the morphologic right ventricle, is also a rare anomaly; its frequency has been reported as approximately 0.09 case per 1,000 birth. DORV associated with DCRV, unusual combination, is even more rare; only a few known cases have been recorded previously in the literature. This report presents our surgical experience with this rare anomaly, DORV with DCRV.

  • The authors report a case of atypical meningioma in the fourth ventricle. Intraventricular meningioma is not uncommon intracranial neoplasm, especially that in the trigone of lateral ventricle, however, those in the third and fourth ventricle are very rare. There are only two cases of atypical meningiomas in the fourth ventricle among 29 cases of fourth ventricular meningiomas reported 17 literature. The clinical features, findings of magnetic resonance image and operation of our case, and review of literature are presented.

  • Various grading systems and surgical techniques have been developed for the treatment of intraventricular hemorrhage (IVH); however, little attention has been paid to the fourth ventricle hematoma. Nonetheless, hemorrhagic dilation of the fourth ventricle may lead to catastrophic consequences for patients with massive IVH. We present two cases of massive IVH accompanied by massive fourth ventricle hematoma which was successfully removed with combination of suboccipital craniotomy for fourth ventricle hematoma and intraventricular fibrinolysis for supratentorial hematoma.

  • A 31-year-old man was admitted to our hospital due to hydrocephalus with neurosarcoidosis. Ventriculo-peritoneal shunting was performed in the right lateral ventricle with intravenous methylprednisolone. Subsequently, after 4 months, additional ventriculo-peritoneal shunting in the left lateral ventricle was performed due to the enlarged left lateral ventricle and slit-like right lateral ventricle. After 6 months, he was re-admitted due to upward gaze palsy, and magnetic resonance image showed an isolated fourth ventricle with both the inlet and outlet of fourth ventricle obstructed by recurrent neurosarcoidosis. Owing to the difficulty of using an endoscope, we performed neuronavigator-guided ventriculo-peritoneal shunting via the left lateral transcerebellar approach for the treatment of the isolated fourth ventricle with intravenous methyl prednisolone. The patient was discharged with improved neurological status.

  • This paper proposed a curve progress control function of the area base instead of the existing edge indication function, in order to detect the brain ventricle area by utilizing a geodesic active contour model. The proposed curve progress control function is very effective in detecting the brain ventricle area and this function is based on the average brightness of the brain ventricle area which appears brighter in MRI images. Compared numerically by using various measures, the proposed method in this paper can detect brain ventricle areas better than the existing method. By examining images of normal and diseased brain's images by brain tumor, we compared the several brain ventricle detection algorithms with proposed method visually and verified the effectiveness of the proposed method.

  • In this paper, we propose an automatic left ventricle segmentation method in computed tomography angiography (CTA) using separating energy function. First, we smooth the images by applying anisotropic diffusion filter to remove noise. Secondly, the volume of interest (VOI) is detected by using k-means clustering. Thirdly, we divide the left and right heart with split energy function. Finally, we extract only left ventricle from left and right heart with optimizing cost function including orientation term.
