Background Aortic Coarcatation (CoA) is one of the congenital heart diseases with the rate of 5-8% of Coronary heart diseases(CHDs). Balloon angioplasty is now one of the effective way of treatment for CoA, native or Re-coarctation (Re-CoA). We aimed to assess the immediate, and short term response to angioplasty and stenting, and also complications. Materials and Methods Balloon angioplasty wi...

BACKGROUND/AIMS Pneumatic dilatation of the oesophagus is a well established treatment for achalasia. Oesophageal perforation is the most serious complication that occurs in 2% to 6% of cases. The aim of this retrospective survey was to identify predictive risk factors for perforation in a consecutive series of 218 patients with achalasia. METHODS Between 1983 and 1993, 270 pneumatic dilatati...

OBJECTIVE To perform an economical single-step renal dilatation (RD) during percutaneous nephrolithotomy (PCNL), using directly a 30-F Amplatz dilator over the central Alken dilator, in a trial to reduce the operative duration and radiation exposure during RD while avoiding an exchange of dilators that might increase the risk of blood loss. PATIENTS AND METHODS In a prospective randomised stu...

conclusions the present case appears to offer a safe and relatively simple method of balloon dilatation inside the lumen of the embolized fragment when the foreign body is too distal to retrieve with conventional snare systems. introduction increasing numbers of complex percutaneous coronary interventions have been accompanied by various intra-procedural complications. the fracture and emboliza...

soon after successful results of balloon valvuloplasty in treatment of congenital pulmonary stenosis, use of this technique for relief of congenital aortic stenosis (as) was attempted in different parts of the world. with the purpose of assessment the value of valvuloplasty in comparison with surgical valvotomy in relief of congenital as, we retrospectively studied 115 patients with valvar as, ...

background: percutaneous balloon mitral valvotomy (bmv) is the gold standard treatment for rheumatic mitral stenosis (ms) in that it causes significant changes in mitral valve area (mva) and improves leaflet mobility. development of or increase in mitral regurgitation (mr) is common after bmv. this study evaluated mr severity and its changes after bmv in iranian patients. methods: w e prospecti...

OBJECTIVE A new second-generation balloon dilatation device for percutaneous nephrolithotomy (PCNL) has been launched, promising to challenge the traditional Amplatz serial dilators (ASDs). This device allows for the polyurethane sheath to be deployed on balloon inflation. Our primary objective in this pilot study was to determine whether the use of this new device impacted on overall patient o...

statement of problem comprehensive diagnosis is regarded as an important base for orthodontic treatment. an effective way to achieve a correct diagnosis is to compare the craniofacial skeleton of patients with normal cases in the same race through lateral cephalograms. purpose the present study was designed to determine the cephalometric norms of senior high school students in the city of hamed...

balloon angioplasty for aortic coarctation was introduced in 1979 for the fust time.1 this procedure soon became the choice treatment for restenosis of operated coarctation,2-5 but remains controversial for native (unoperated) coarctation. however, it seems to be rapidly becoming the intervention of choice for relief of unoperated coarctation as well. in this study, we evaluate the outcome of t...

critical pulmonary valve stenosis (cpvs) and atrial septal defect (asd) is an uncommon form of congenital heart disease. concurrent transcatheter pulmonary valvuplasty and closure of secundum atrial septal defect appears to be an interesting alternative to surgical correction. we present the simultaneous balloon valvuloplasty of critical pulmonary stenosis (ps) with supra systemic right ventric...
