Pulmonary valve stenosis was relieved by balloon dilatation during cardiac catheterisation on 27 occasions in 23 infants and children aged 7 days to 12 years, median 31 months (three aged less than 2 weeks). Pulmonary valve diameter was estimated by cross sectional echocardiography to assist in the choice of balloon size. Before dilatation the right ventricular systolic pressure ranged from 41 ...

BACKGROUND The results of immediate and short term follow up of balloon dilatation of the pulmonary valve have been well documented, but there is limited information on long term follow up. OBJECTIVE To evaluate the results of three to 10 year follow up of balloon dilatation of the pulmonary valve in children and adolescents. SETTING Tertiary care centre/university hospital. DESIGN Retros...

OBJECTIVE To review the presentation of tubercular ureteric strictures and assesses the role of balloon dilatation and open surgical repair in their management. METHODS This was a retrospective review of tubercular ureteric strictures managed between January 1993 and December 2002. The records were analyzed to assess clinical presentation and compare the results of balloon dilatation with ope...

BACKGROUND Exertional dyspnoea is a limiting symptom in many patients with mitral stenosis but its causes remain incompletely understood. Ventilation during exercise is abnormal in chronic heart failure of all causes and there is increased ventilatory cost of carbon dioxide production. PATIENTS 23 patients with rheumatic mitral stenosis undergoing percutaneous balloon dilatation of the mitral...

AIM To evaluate the safety and efficacy of upper esophageal sphincter (UES) dilatation for cricopharyngeal (CP) dysfunction. To determine if: (1) indication for dilatation; or (2) technique of dilatation correlated with symptom improvement. METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dila...

BACKGROUND AND OBJECTIVES We investigated the effectiveness of balloon dilatation of homograft conduits in the pulmonary position in delaying surgical replacement. SUBJECTS AND METHODS We reviewed the medical records of patients who underwent balloon dilatation of their homograft in the pulmonary position from 2001 to 2015. The pressure gradient and ratio of right ventricular pressure were me...

PURPOSE We retrospectively investigated the feasibility and clinical efficacy of balloon dilatation and subsequent retrievable stent insertion, when necessitated, for pyloric spasms after pylorus-preserving gastrectomy (PPG). MATERIALS AND METHODS Forty-five patients experiencing pyloric spasms after PPG underwent fluoroscopic balloon dilations to alleviate obstructive symptoms due to delayed...

Percutaneous balloon dilatation has been used successfully to dilate various stenoses occurring after repair of congenital heart disease. Acute dissection of a stenotic right ventricular outflow tract occurred after attempted balloon dilatation in a patient with previously corrected tetralogy of Fallot.

Objective: Balloon dilatation of Primary Achalasia Cardia (PAC) is usually performed under antegrade endoscopic guidance, with conscious sedation. The main goals of this prospective study were to assess the safety and efficacy of pneumatic dilatation without conscious sedation and to determine the endoscopic signs of effacement of the balloon”waist”. Methodology: Pneumatic dilatation was succes...

Three patients developed protein-losing enteropathy caused by intra-atrial obstruction of the systemic venous return after Mustard's operation. The enteropathy resolved in one case after reoperation and in the others after balloon dilatation of the stenosed caval pathways. Protein-losing enteropathy may occur as a complication of Mustard's operation. Balloon dilatation of the obstructed baffle ...
