Anomalous origin of coronary artery originating from the pulmonary artery in conjunction with the aorticopulmonary window (APW) is a rare but a significant anomaly in the era of congenital cardiac diseases. The occurrence of anomalous origin of the right coronary artery from the pulmonary artery among the associated anomalies is less than 5%. The severity of the clinical condition of these patients depends on the degree of left-right shunt and compromise of the pulmonary blood flow. We report surgical management of a case of a 45-day-old infant with APW, ventricular septal defect, and anomalous origin of coronary artery originated from the pulmonary artery.

An optimal result is often difficult to obtain with conventional banding of the pulmonary trunk. Furthermore, this procedure has a significant surgical morbidity and mortality. An inflatable device has therefore been developed which consists of an inflatable band and a valve. The band is made of a silicone balloon which is covered with reinforced braid. The band is applied loosely around the pulmonary trunk through a left lateral thoracotomy. The valve is implanted subcutaneously in an intercostal space. The size of the band can be adjusted postoperatively using a needle and fluid-filled syringe percutaneously to inflate or deflate the balloon. Experiments were conducted in 5 animals and follow-up evaluation by cardiac catheterization and angiocardiography was made up to 4 months after implantation of the device. The band could be effectively and reliably adjusted and no malfunction or complication occurred. This preliminary study suggests that this new technique may make banding of the pulmonary trunk a more reliable and effective procedure and may reduce surgical morbidity and mortality. It also may avoid or delay subsequent additional surgery for revision of a band which is too tight or too loose.

Pulmonary artery sarcomas (PAS's) are extremely rare malignant tumors that arise from the endothelial lining of the pulmonary arteries. On CT scans PAS's appear as intraluminal filling defects in the pulmonary arteries, mimicking pulmonary embolism (PE). Due to the similarities in radiographic features as well as in clinical presentation, PAS's are usually misdiagnosed as pulmonary embolism. Since PASs are F-18 FDG avid, F-18 FDG PET/CT scan is a useful imaging tool for differentiating between these two conditions, as shown in this case report. We report a case of a 60-year-old woman presented with a 6-month history of chest pain, dyspnea on exertion, non-productive cough and weight loss. The initial CT pulmonary artery angiography showed extensive intraluminal mass in the pulmonary trunk and left pulmonary artery, diagnosed as massive pulmonary embolism. Since there was no clinical improvement after anticoagulant therapy, CT pulmonary angiography was repeated, and with no change observed in the intraluminal filling defect in pulmonary trunk, the possibility of tumor was raised. For further evaluation of a possible malignancy, F-18 FDG PET/CT was performed. It showed increased FDG uptake, suspicious for an aggressive tumor, in the intraluminal lesion of the pulmonary trunk and along the wall of the left pulmonary artery. There was no extrathoracic abnormality seen on PET/CT scan. Histopathological finding after complete pulmonary artery resection showed high grade undifferentiated pleomorphic sarcoma. F-18 FDG PET/CT is a useful tool for differentiating between pulmonary embolism and malignant intraluminal mass, and at the same time it enables the proper staging of the malignancy. < p > < /p >.

The surface of the endothelial cells of the pulmonary trunk of the Wistar albino rat was studied by means of silver preparations and by scanning and transmission electron microscopy. This surface is the site of cytoplasmic projections and the opening of caveolae which together appear to be features associated with the active metabolic rôle of the pulmonary endothelial cell.

A pulmonary artery aneurysm is a rare, heterogeneous disease for which there are currently no surgical guidelines. We present the case of a symptomatic patient presenting with a large aneurysm of the distal pulmonary trunk and left pulmonary artery. The aneurysm was resected through a full median sternotomy under cardiopulmonary bypass and aortic cross-clamping. The reconstruction was performed using a straight vascular prosthesis to connect the proximal pulmonary trunk to the left pulmonary artery with the lateral reimplantation of the right pulmonary artery. We find this surgical technique to be simple, effective, and reproducible by colleagues encountering similar cases.

OBJECTIVE
Establishing a new continuity between the right ventricle and the pulmonary artery is the mainstay of repair for persistent truncus arteriosus. We used the Tran Viet-Neveux technique without a Lecomte maneuver to construct the connection without a conduit. Here, we retrospectively review the mid-term surgical results to examine the effectiveness of this approach.
METHODS
A cylindrical segment incorporating both pulmonary artery branches was sleeve-resected from the truncal artery. The cylindrical segment was cut in the middle and two truncal arterial flaps were combined to form the posterior floor of the new pulmonary arterial trunk. The edge of the floor was attached directly to the superior margin of an oblique incision made in the left-anterior wall of the right ventricle. A polytetrafluoroethylene monocusp was attached to the lower half margin of the right ventricular incision. A large glutaraldehyde-treated pericardial patch was used to form the anterior hood of the new right ventricular outflow tract. Both great arteries were located in a normal spiral configuration.
RESULTS
Ten babies (range: 3 days to 9 months of age) underwent this procedure. The Collett-Edwards classification of persistent truncus arteriosus was type I in five cases and type II in five others. There was one hospital death due to severe respiratory distress. During follow-up (36-60 months, median 54 months), only one re-operation was required to enlarge a left branch pulmonary artery stenosis. Follow-up echocardiography showed pulmonary regurgitation (mild two, moderate seven, and severe one) and mild flow acceleration in the left pulmonary artery branch and right ventricle-pulmonary artery connection in one case.
CONCLUSION
This simple modification for surgical correction of persistent truncus arteriosus may be an effective alternative that overcomes conduit-related problems.

Pulmonary artery (PA) catheterisation has been performed for over four decades. It is utilised in intensive care units and perioperatively to titrate fluid and pressor therapy. Major and minor complications have been reported. The catheter can infrequently loop and coil in the right atrium, right ventricle and superior vena cava .We report a case of coiling of the PA catheter in the main PA. A 33-year-old woman was admitted with multiorgan failure and shock. She required mechanical ventilation, was in severe pulmonary oedema and required vasopressors for shock. We placed a PA catheter to assist in the management of her haemodynamic collapse. The catheter coiled in the main pulmonary trunk, which is extremely rare. The catheter was removed without any complications.

Spontaneous rupture of the main pulmonary trunk is a very uncommon complication of severe pulmonary hypertension. The condition manifests as sudden death or cardiogenic shock usually diagnosed postmortem. We report the case of a 65-year-old-women with severe pulmonary hypertension and hereditary hemorrhagic telangiectasia, among other diseases, evaluated due to severe epistaxis. Initial evaluation was performed and during observation, the patient developed sudden cardiac death. Autopsy revealed rupture of the main pulmonary trunk as the cause of death.

BACKGROUND/AIM
Hypoplastic left heart syndrome (HLHS) is a rare pathology with a very high mortality rate. The present study aimed to share our initial experience with the ductus arteriosus stenting procedure using the pulmonary trunk approach in the treatment of HLHS, as well as provide some technical suggestions and discuss complications and their management.
MATERIALS AND METHODS
The medical records of 9 neonates (age range: 1–8 days) with HLHS, who were operated on within a 12-month period, were reviewed retrospectively. Preprocedural planning was performed by computed tomography angiography and echocardiography. The operations were performed in a hybrid surgery room by interventional radiologists and pediatric vascular surgeons. Balloon-expandable stents were used in all of the operations.
RESULTS
All operations were successfully completed without any intraoperative mortality. All intraoperative complications were managed successfully during the stenting procedure.
CONCLUSION
Stage 1 hybrid palliation for HLHS is a safe and effective procedure when several key points are kept in mind.
