1/194. The use of transesophageal echocardiography to evaluate the effectiveness of patent ductus arteriosus ligation.The ligation of patent ductus arteriosus (PDA) is a comparatively easy operation, but some complications are possible. The most common complication is incomplete ligation of the PDA; others include inadvertent ligation of the descending aorta or left pulmonary artery, transient rise in systemic blood pressure and increased left ventricular afterload, and acute right heart failure due to pulmonary hypertension. The completeness of the PDA ligation is usually determined only by the operating physician's experience, including the use of an esophageal stethoscope or a finger on the lesion to feel for vibration. These methods sometimes fail to detect an incomplete ligation. With transesophageal echocardiography (TEE), we have monitored the entire course of the PDA ligation directly without interrupting the surgical procedure, and precisely determined the completeness of the ligation. We also expect that TEE will enable us to avoid other complications as well.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/194. High origin of the right coronary artery with congenital heart disease.We encountered a case of anomalous high origin of the right coronary artery associated with ventricular septal defect and patent ductus arteriosus. The right coronary artery originated from the distal part of the ascending aorta resulting in unsuccessful induction of cardiac arrest by cardioplegia. We describe this rare case with anomalous origin of the right coronary artery.- - - - - - - - - - ranking = 7keywords = artery (Clic here for more details about this article) |
3/194. Thrombotic occlusion of the main stem of the left coronary artery in a neonate.Thrombotic coronary arterial occlusion, and myocardial infarction, are rare in the newborn. We report such a happening presenting shortly after birth with cardiogenic shock, no left ventricular output and a systemic circulation dependent on flow from a patent arterial duct.- - - - - - - - - - ranking = 4keywords = artery (Clic here for more details about this article) |
4/194. Aneurysm of the pulmonary trunk with patent arterial duct.We present a 14-year-old female with a massive aneurysm of the pulmonary trunk occurring secondary to bacterial endocarditis of the patent arterial duct. Echo Doppler imaging, magnetic resonance and angiography confirmed the diagnosis. On intermediate follow-up after surgical correction, the echo studies and cardiac catheterization disclosed no residual lesions. The patient is now asymptomatic.- - - - - - - - - - ranking = 51.071746059382keywords = aneurysm (Clic here for more details about this article) |
5/194. Right aortic arch with isolation of the left subclavian artery, moderate patent ductus arteriosus, and subclavian steal syndrome: A rare aortic arch anomaly treated with the Gianturco-Grifka vascular occlusion device.We present the first described use of the Gianturco-Grifka Vascular Occlusion Device to close a moderate patent ductus arteriosus associated with the rare congenital condition of right aortic arch with isolation of the left subclavian artery. Left vertebral artery "steal" through the moderate patent ductus arteriosus was eliminated by this transcatheter technique. Cathet. Cardiovasc.

6/194. pulmonary artery aneurysm.Main pulmonary artery aneurysm is an exceedingly rare entity. We present a case of main pulmonary artery aneurysm with patent ductus arteriosus in a sixty-year-old woman. The aneurysm was successfully treated with aneurysmectomy and primary anastomosis of the defect of the main pulmonary artery, and the patent ductus arteriosus was divided. The etiology, operative indication and surgical intervention of main pulmonary artery aneurysm are discussed along with a review of the literature.- - - - - - - - - - ranking = 470.15101230188keywords = aneurysm, artery, artery aneurysm (Clic here for more details about this article) |
7/194. Subclinical aortic perforation with the infant double-button patent ductus arteriosus occluder.Modification of the double-button (Sideris) patent ductus arteriosus (PDA) occluder has resulted in a single-strut aortic component rather than the conventional cross-strut design. We report the use of this infant PDA occluder for transcatheter closure in three patients with PDA measuring 2 mm, 3.7 mm, and 4 mm. Subclinical aortic perforation with a small aortic aneurysm developed in two patients 1 year after occluder implantation. The third patient had developed a small aortic aneurysm without perforation at 3-month follow-up. All three patients had a residual shunt and underwent successful PDA surgical closure with aortic aneurysmal repair. Single-strut umbrella designs are not recommended for PDA transcatheter closure.- - - - - - - - - - ranking = 153.21523817815keywords = aneurysm (Clic here for more details about this article) |
8/194. Spontaneous closure and thrombosis of a ductal aneurysm in a neonate.The natural history of a ductal aneurysm detected prenatally is presented.

9/194. Embolization of Gianturco coil into the pulmonary artery requiring emergency surgical intervention.We report the case of a 20-month-old girl who underwent Gianturco coil embolization to a patent ductus arteriosus in May 1997. The coil migrated to the pulmonary artery. After unsuccessful attempts to retrieve it with snares and forceps, we engaged the coil with an end-hole balloon catheter and pulled it down to the right ventricle. There it became entangled in the tricuspid valvular apparatus and could not be moved farther. Due to concerns about sequelae, the patient was referred for surgery. Following a mid-sternotomy under cardiopulmonary bypass, we removed the coil and ligated the patent ductus arteriosus. The patient made an uneventful recovery. A brief review of the literature is presented.- - - - - - - - - - ranking = 5keywords = artery (Clic here for more details about this article) |
10/194. Successful resection of ductus arteriosus aneurysm in infancy.We report a case of thrombosed patent ductus arteriosus aneurysm in an infant. The aneurysm was detected accidentally on chest roentgenogram and presented as globular soft tissue density mass in left posterosuperior mediastinum. Resection of the aneurysm was performed without cardiopulmonary bypass. Two years after operation the patient is well and growing normally.- - - - - - - - - - ranking = 357.50222241568keywords = aneurysm (Clic here for more details about this article) |
