Right pulmonary artery?Cto?Cleft atrial communication is a rare congenital vascular malformation that results in a right-to-left shunting. This report describes the case history of a neonate with a large right pulmonary artery?Cto?Cleft atrial connection resulting in cyanosis and severe heart failure who underwent successful early catheter interventional therapy. In the neonate, this lesion can be diagnosed accurately using transthoracic echocardiography. Closure of the communication can be achieved even in infants via percutaneous interventional catheterization with a low procedure-related risk and a good midterm follow-up result. 相似文献

Proximal stenosis adjacent to the orifice of one or both coronary arteries may occur after the arterial switch operation (ASO) for d-transposition of the great arteries (d-TGA). Coronary artery stenosis (CAS) often progresses within the first 6 months postoperatively and may result in myocardial ischemia and infarction. Although percutaneous transluminal coronary balloon angioplasty (PCBA) for CAS within 15 months after ASO for d-TGA has been reported, there is no report of PCBA for CAS in the late period after ASO. We present the results of PCBA for CAS of the left coronary artery performed more than 10 years after ASO in an 11-year-old boy and a 14-year-old boy without complication. The stenosis degree improved in both patients from 81 to 45 and 80 to 54 %, respectively. Restenosis did not occur, and the stenosis degree improved to about 25 % late after PCBA. Although the initial effect of PCBA may not be dramatic, it can improve late after PCBA. It was considered that the optimal balloon–reference vessel ratio was about 1.0, to obtain the minimal effective lumen diameter. PCBA for CAS even if performed many years after ASO is feasible without complication. PCBA can also provide delayed improvement late after the procedure. 相似文献

We report a symptomatic newborn with Osler–Rendu–Weber syndrome, multiple and diffuse pulmonary arteriovenous malformations,
and right-to-left shunting in the left lung. Right-to-left shunting was significantly decreased by selectively banding the
left pulmonary branch artery and clipping one large feeding vessel so that total resection of the left lung could be avoided. 相似文献

Outcomes After “Unroofing” of a Myocardial Bridge of the Left Anterior Descending Coronary Artery in Children with Hypertrophic Cardiomyopathy 总被引:1,自引:0,他引:1
The importance of myocardial bridging of a coronary artery in the setting of hypertrophic cardiomyopathy is controversial, although we have previously reported an association with myocardial ischemia and sudden death in children. We report five symptomatic children in whom symptoms or evidence of myocardial ischemia resolved or improved after supraarterial myotomy alone. 相似文献

We performed a retrospective echocardiographic study in tetralogy of Fallot (TOF) or pulmonay atresia with ventricular septal
defect (PA&VSD) to evaluate the effects of Blalock–Taussig shunt on branch pulmonary artery growth. There were 35 patients
with TOF and 11 with PA&VSD. We measured the right and left pulmonary artery area index and also the combined pulmonary artery
area index, both before and after shunt operation. The mean ± SD of these three variables before the shunt operation in the
TOF group were 63.5 ± 22.5, 57.8 ± 24.9, and 121.4 ± 42.8 mm2/m2; after shunt operation they were 98.5 ± 33.6, 85.9 ± 31.9, and 184.0 ± 59.8 mm2/m2, respectively (p values <0.0001, <0.0002, and <0.0001, respectively). In the PA&VSD group the comparable values before shunt operation were
66.5 ± 16.0, 55.4 ± 10.6, and 120.9 ± 26.9 mm2/m2 and after shunt operation were 90.5 ± 22.9, 77.2 ± 24.1, and 166.6 ± 44.4 mm2/m2, respectively (p values <0.0006, <0.014, and <0.002, respectively). We also examined the effect of distensibility of pulmonary arteries by
comparing the percentage change in size of the combined pulmonary artery area index in the first 4 months after shunt with
those after this time (p < 0.023). There were no significant differences between left- and right-sided shunts, origin and distal pulmonary artery
growth, and the TOF and PA&VSD groups. 相似文献
