Neonatal right Lung Emphysema due to Pulmonary Artery Sling
No full textPulmonary artery sling is a rare variant of vascular ring where the left pulmonary artery arises from the right and loops behind the trachea or right bronchus causing airway compression. A 40-day-old infant had been mechanically ventilated since birth for severe hypercapnia and right lung emphysema. Left pulmonary artery reimplantation was successfully performed
Type A Aortic Dissection in an 11-month-old Infant With Loeys-Dietz Syndrome
No full textType A aortic dissection is a very uncommon finding in children, especially among infants, where no cases seem to have been described. We report the case of an 11-month-old boy with Loeys-Dietz syndrome and asymptomatic type A aortic dissection involving the aortic root that was successfully repaired
The Norwood operation performed with the heart beating and no prosthetic materials
No full textThe Norwood procedure performed with the heart beating is a useful and attractive way to perform the stage I palliation for hypoplastic left heart syndrome. It allows completion of the surgical procedure without stopping the heart and without using deep hypothermia and circulatory arrest. Therefore it could be an attractive solution for reducing the adverse effects of the operation and the rate of postoperative complications. Moreover, this technique avoids the use of prosthetic materials, thus minimizing long-term complications and reoperations, and promotes a more physiological growth of the anatomical structures. However, the high level of expertise required to perform this type of complex neonatal procedure with the heart beating may be limited to only a few centers in the world thus far
Hypoplastic left heart syndrome in situs inversus totalis
No full textA very rare case of a newborn with hypoplastic left heart syndrome and situs inversus totalis is herein reported. Successful surgical treatment of this cardiac malformation was accomplished at our institution and consisted of: modified Norwood stage I procedure, with direct anastomosis of the transected main pulmonary artery to the aortic arch, without any prosthetic material interposition and right ventricle to pulmonary artery polytetrafluoroethylene shun
Adjustable aorto-pulmonary shunt to prevent temporary pulmonary over-circulation.
No full textThe Blalock-Taussig shunt can produce a temporary pulmonary over-circulation and can be downsized with a metallic clip. This hemodynamic situation can be reversible leading to desaturation. We describe a very simple method to resize temporarily the shunt with a removable metallic cli
Neonatal aortic arch surgery
No full textSurgical repair of the aortic arch is entailed in the neonatal period of patients with: hypoplastic left heart syndrome, interrupted aortic arch, hypoplastic aortic arch and complex aortic coarctation. Aortic arch surgery requires a period of circulatory arrest and deep hypothermia. Cerebral selective perfusion has recently been introduced as an alternative to circulatory arrest with the aim of reducing mortality and neurological complications. Moreover, the arch reconstruction phase can be safely performed under moderate hypothermia and with cerebral and myocardial perfusion (on beating heart), thus, completely avoiding cerebral ischemia and completely avoiding or drastically reducing myocardial ischemi
Systemic venous segments interposition for pulmonary artery to aorta connection
No full textTwo patients with pulmonary atresia and ventricular septal defect underwent implantation of the diminutive pulmonary arteries on the ascending aorta by interposition of short segment of azygos and innominate veins. The very thin structure of the systemic veins' wall matched perfectly the fragile pulmonary arterial wall. The anastomosis were perfectly patent and no aneurism dilatation was evident after 3 and 4 months respectively. Keywords: Biomaterials; Congenital heart disease; Pulmonary arteries
Resternotomy in pediatric cardiac surgery: CoSeal initial experience.
No full textSternal re-entry adds supplementary risk to cardiac re-operations and it may represent the most important factor in the entire hazard estimation. A new anti-adhesive substance, based on a polyethylene glycol material, has been proposed to solve this problem. Results and surgical observations at chest re-entry in five patients treated with this synthetic polymer are herein discussed
Tetralogy of Fallot with coronary-to-pulmonary artery fistula: a diagnostic snare.
No full textAn 11-month-old infant, moderately cyanotic, with diagnosis of tetralogy of Fallot underwent corrective surgery. At echocardiographic evaluation, a subatretic right ventricular outflow tract without aortopulmonary collateral arteries, confluent pulmonary arteries and normal coronary pattern were evidenced. During operation, an undiagnosed large coronary-to-pulmonary artery fistula was disclosed. Because of the large variety of aortopulmonary collateral arteries that can be associated with this pathology, further imaging study is mandatory when oxygen saturation does not match the right ventricular outflow tract obstruction severity
Arterial switch operation for a complex transposition of the great arteries in dextrocardia.
No full textA very rare case of a newborn with dextrocardia, complete transposition of the great arteries {S,D,D}, ventricular septal defect, aortic arch hypoplasia, juxtaposition of the morphologically right atrial appendage and superoinferior ventricles is herein presented. He successfully underwent arterial switch operation, ventricular septal defect closure and aortic arch reconstruction with end to end extended direct anastomosi
