Permanent complete heart block developed in a five year old child during balloon dilatation for pulmonary valve stenosis. Damage to the atrioventricular node by pressure from the inflated balloon may have caused the conduction defect.

BACKGROUND AND AIMS There is a high rate of stricturing post-operative recurrence in Crohn's disease (CD) particularly at sites of surgical anastomosis, and over 50% of these patients will require a repeat resection. Endoscopic dilatation of anastomotic strictures is an alternative to surgical resection in selected patients. We aimed to evaluate the safety and long term efficacy of endoscopic b...

Coarctation is a narrowing of the aorta located between the first brachiocephalic vessel and the aortic bifurcation. When isolated coarctation is associated with congestive heart failure, it is considered clinically important,2 but what is "important" when the child is asymptomatic? Shaddy et all use as an entrance criterion "hemodynamically significant native coarctation of the aorta" without ...

Balloon dilatation of the aortic valve was attempted in 34 consecutive children aged 16 months to 17 years (median 7 years), weight range 9-60 (median 22) kg. Previous surgical valvotomy had been performed in two patients (twice in one of them). The valve was not crossed in one patient. In the remaining 33 patients the pressure difference between the left ventricle and the ascending aorta durin...

conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...

BACKGROUND Tracheobronchial stenosis is a known complication of endobronchial tuberculosis. Despite antituberculous and steroid therapy, the development of bronchial stenosis is usually irreversible and requires airway patency to be restored by either bronchoscopic or surgical interventions. We report the use of balloon dilatation and topical mitomycin-C to successful restore airway patency. ...

BACKGROUND Carcinoid heart disease typically results in pulmonary stenosis and tricuspid incompetence. Percutaneous balloon dilatation is an effective treatment for congenital pulmonary stenosis and has been applied successfully to tricuspid stenosis caused by carcinoid heart disease. The value of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis was assessed. METHODS ...
