A 15-year-old girl underwent successful surgical correction of double-outlet right ventricle [S.D.L.] subaortic ventricular septal defect, patent foramen ovale, and pulmonary hypoplasia with valvular stenosis. The operation consisted of an internal baffling connecting the left ventricle to the aorta through the ventricular septal defect. The pulmonary stenosis was corrected with the method of connection the right ventricle to the pulmonary artery bifurcation using the Hancock valve[18mm] contained conduit. This rare type of DORV seemed to be suitable for corrective surgery, and the patient`s condition is very good until present time (post operative 7 months).

Four to seven percent of infants born with aortic atresia have a normal-sized left ventricle in association with a ventricular septal defect and a normal mitral valve. In contrast to the more common group of infants with aortic atresia whose left ventricle is hypoplastic, this important subgroup has potential for complete operative correction involving both the right and left ventricle. Our approach was to perform complete repair at one stage. The patient who underwent single-stage repair was discharged from the hospital in good condition. Achieving a physiologically normal circulation simplifies the postoperative management of this condition.

The syndrome of anomalous muscle bundle dividing the right ventricle into two pressure chambers has been described by many authors. The malformation should not be confused with tetralogy of Fallot itself because the obstructive hypertrophic bands are usually proximal to the right ventricular infundibulum. One case [11 years old male] of double chambered right ventricle due to aberrant muscle bundle with intact ventricular septum is presented. The pressure gradient was 68 mmHg between inflow and outflow tracts of right ventricle on cardiac catheterization. On opening the right ventricle, there noted stenosis of outflow tract by infundibular membrane, hypertrophied anomalous muscle bundle, thickened moderator band & hypertrophied anterior papillary muscle. Open heart surgery was carried out with the aid of extracorporeal support, Anomalous muscle bundle [1.0 cm x 4.0 cm] and infundibular membrane were resected safely. The hypertrophied moderator band was cut at mid-portion and anterior papillary muscle was split vertically. The postoperative course was uneventful and discharged in good condition 2 weeks later.

Chordoid glioma is a rare primary brain tumor of the third ventricle, and was recently characterized as a novel tumor entity. Typical radiological features of chordoid gliomas include; a solid, round-to-ovoid, well-circumscribed, contrast-enhancing mass of the hypothalamus and anterior third ventricle. Despite being classified as WHO grade 2, the third ventricular chordoid glioma has been reported to have a poor clinical outcome because of its anatomical location. The authors report a case of chordoid glioma of the third ventricle in a 48-year-old man with unusual radiological features of cystic component and ill defined circumscription.

Speckle noise reduction for power Doppler ventricle coherent image for restoration and enhancement using Fast Wavelet Transform with multi-thresholding and multi-filtering on the each subbands is presented. Fast Wavelet Transform divides into low frequency component image to high frequency component image to be multi-resolved. Speckle noise is located on high frequency component in multi-resolution image mainly. A Doppler ventricle image is transformed and inversed with separated threshold function and filtering from low to high resolved images for restoration to utilize visualization for ventricle diagnosis. The experimental result shows that the proposed method has better performance in comparison with the conventional method.

In this study we propose the computational model for the coronary circulation. The bypass from left ventricle is also considered. Lumped parameter model with three compartments in the coronary circulation is implemented in this study. We connected the coronary artery compartment with left ventricle to explain the bypass procedure from left ventricle. The asymmetric resistance is assumed in the bypass line from left ventricle. The present numerical method is tested for normal coronary circulation and the results are compared with the existing computational work. The bypass simulation is conducted and the flow pattern is delineated. The effect of shunt resistance and coronary compliance to circulation is investigated for the better design of the bypass shunt.

Within the group of congenital cardiac anomalies manifesting atrioventricular discordance, there exists a subset of hearts characterized by the additional presence of double outlet of the morphological right ventricle. Most of these hearts have associated pulmonary stenosis and abnormal direction of the cardiac apex, and all have a ventricular septal defect. Recently, a 10-year old boy underwent successful surgical correction of double outlet right ventricle with atrioventricular discordance. Diagnostic confirmation was made by 2-D echocardiography, cardiac catheterization and cineangiocardiography. The operation consisted of patch closure of ventricular septal defect so as to leave both great arteries draining the systemic[morphologically right] ventricle, and insertion of an extracardiac valved conduit between the morphological left ventricle and the distal end of the proximally oversewn pulmonary artery. Postoperative course was uneventful.

Obstruction of the right ventricular outflow tract occurs in many various positions. Recently, obstruction due to anomalous muscle bundle has been clearly recognized. This anomaly is caused by a large anomalous muscle bundle, which creates an obstruction low in the body of the right ventricle and divides it into two chambers. Three cases of double chambered right ventricle were treated surgically utilizing cardiopulmonary bypass in the Department of Chest Surgery, College of Medicine, Seoul National University. 1] All of the 3 cases were female. 2] In 2 cases, FKG findings were RVH and RAD, but in case 2, normal EKG findings. 3] In case 2, no pressure gradient between the inflow portion and outflow portion of the right ventricle was observed, but in case 1 and 3, pressure gradients were 70 and 64 mmHg, respectively. 4] In 2 of the 3 cases, type II VSD was combined to double chambered right ventricle. 5] All of the 3 cases were discharged with symptomatic improvement after operation.

Double-chambered right ventricle [DCRV] is a rare congenital heart disease caused by anomalous muscle bundle traversing the sinus portion of the right ventricle well beneath the infundibulum. Recently we have experienced a case of DCRV with ventricular septal defect in 7-year old male patient. Preoperative cardiac catheterization and cineangiography revealed 80 mmHg pressure gradient between the proximal and distal chamber of the right ventricle and diagonal shape filling defect by the anomalous muscle bundle in the sinus portion of the right ventricle. Resection of the anomalous muscle bundle and patch closure of the ventricular septal defect was performed with cardiopulmonary bypass. The postoperative course was uneventful and excellent.

A 12-month-old, 3.0-kg, male, Scottish fold cat was referred to Irion animal hospital with dyspnea and cardiac murmur. In radiograph, right-sided cardiomegaly and pleural effusion were identified. In echocardiographic examination, abnormal stenotic region was identified in right ventricle and dilation of right atrium and concentric hypertrophy of interventricular septum and the free wall of right ventricle were also identified. In the stenotic region, abnormal muscular band was identified. The turbulent flow was identified in infundibular region of right ventricular outflow tract with color-Doppler examination and high velocity flow (4.0 m/s) was also identified in stenotic region. With these results, double-chambered right ventricle (DCRV) was diagnosed.
