Introduction and objectives
Percutaneous pulmonary valvuloplasty is the preferred interventional procedure for pulmonary valve stenosis. The aim of this study was to evaluate the effectiveness of this technique, assess the factors leading to its success, and determine the long-term results in the pediatric population.Methods
The study included 53 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty between December 1985 and December 2000. Right ventricular size and functional echocardiographic parameters, such as pulmonary regurgitation and residual transvalvular gradient, were assessed during long-term follow-up.Results
Peak-to-peak transvalvular gradient decreased from 74 mmHg [interquartile range, 65-100 mmHg] to 20 mmHg [interquartile range, 14-34 mmHg]. The procedure was unsuccessful in 2 patients (3.77%). The immediate success rate was 73.58%. Follow-up ranged from 10 years to 24 years (median, 15 years). During follow-up, all patients developed late pulmonary regurgitation which was assessed as grade II in 58.4% and grade III in 31.2%. There was only 1 case of long-term restenosis (2.1%). Severe right ventricular dilatation was observed in 27.1% of the patients. None of the patients developed significant right ventricular dysfunction. Pulmonary valve replacement was not required in any of the patients.Conclusions
Percutaneous balloon valvuloplasty is an effective technique in the treatment of pulmonary valve stenosis with good long-term results.Full English text available from:www.revespcardiol.org/en 相似文献15.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the triad of epistaxis, telangiectasia and vascular malformations. Pulmonary vascular complications associated with this disease include pulmonary arteriovenous malformations (AVM) and, less frequently, pulmonary hypertension (PH). 相似文献

The increase in survival that has been achieved with the new treatments in the era of highly active antiretroviral therapy, has enabled clinicians and researchers to analyze issues that emerge in the long term in patients with HIV infection. Although the majority of cardiovascular complications have been widely described, the pathogenesis of pulmonary arterial hypertension is still poorly understood, and is one of the more complex and feared complications as it worsens the prognosis and quality of life of these patients 相似文献
