Abstract
In recent decades, tremendous medical advances have been made. Therapeutic cardiac catheterisation for repair of congenital heart defects has become the standard mode of therapy. Catheter techniques have progressed. They now provide temporary palliation, prepare the patient for surgical reconstruction, or offer a definitive repair. The main advantages of non-surgical procedures are avoidance of thoracotomy and cardiopulmonary bypass, together with a shorter hospitalisation period and speedier convalescence.
Paediatric interventions include: transcatheter device closure of congenital cardiac defects, balloon angioplasty and valvuloplasty, atrial septostomy, patent ductus arteriosus stenting in the neonatal period, vessel embolisation, and many others. Topping those interventions is the introduction of transcatheter valve replacement. The aim of this article is to review these interventions and present them in a simplified, vibrant, and up-to-date fashion.
In conclusion, paediatric cardiac interventions have established their reliability and ever-expanding scope in the setting of congenital heart disease management. Nevertheless, success is dependent on selecting the proper procedure for each condition, which may also vary with each patient. Thus, it is highly dependent on the experience and expertise of the operator. With the current rate of technological innovation, more and more surgical procedures will eventually be replaced by catheter-based interventions with a great degree of safety and efficacy.

Abstract
In an era when less invasive techniques are favored, therapeutic cardiac catheterization constantly evolves and widens its spectrum of usage in the pediatric population. The advent of sophisticated devices and well-designed equipment has made the management of many congenital cardiac lesions more efficient and safer, while providing more comfort to the patient. Nowadays, a large variety of heart diseases are managed with transcatheter techniques, such as patent foramen ovale, atrial and ventricular septal defects, valve stenosis, patent ductus arteriosus, aortic coarctation, pulmonary artery and vein stenosis and arteriovenous malformations. Moreover, hybrid procedures and catheter ablation have opened new paths in the treatment of complex cardiac lesions and arrhythmias, respectively. In this article, the main therapeutic utilities of cardiac catheterization in children are discussed.

Abstract
Transcatheter balloon pulmonary valvuloplasty (BPV) is the standard of care in managing symptomatic patients with moderate-to-severe pulmonary valvular stenosis, or asymptomatic patients with severe pulmonary valvular stenosis or with moderate pulmonary stenosis and evidence of objective exercise intolerance or right ventricular dysfunction. This article discusses the incidence, causes, and pathophysiology of valvular pulmonary stenosis in adolescents and adults; its natural history and noninvasive evaluation; the current guideline-recommended indications for BPV; the technical aspects of performing BPV; the immediate and long-term outcomes after valvuloplasty; and the complications and safety of the procedure. Also discussed is the role of this procedure in neonatal critical pulmonary stenosis and in percutaneous pulmonary valve replacement for patients with prior pulmonic valve interventions or degenerated right ventricular pulmonary artery conduits.

Abstract
BACKGROUND Significant infundibular stenosis and significant tricuspid regurgitation (TR) occasionally result from severe pulmonary valve stenosis in adults, and these 2 conditions have an adverse impact on morbidity and mortality in patients who undergo corrective surgery. The goal of this study was (1) to evaluate the long-term (up to 17 years) outcome of pulmonary balloon valvuloplasty (PBV) in adults and (2) to determine the effect of successful PBV on severe infundibular stenosis and severe TR. METHODS Pulmonary balloon valvuloplasty was performed in 90 consecutive patients (49 women, 41 men) of mean age 23 +/- 9 years (range 15-54 years) with congenital pulmonary valve stenosis. Clinical and echocardiographic assessment was performed 2 to 17 years (mean 10 +/- 3.9 years) after PBV. Repeat cardiac catheterization was performed 6 to 24 months after PBV in 43 patients who had concomitant moderate to severe infundibular stenosis (infundibular gradient > or = 30 mm Hg). RESULTS There were no immediate or late deaths. The mean catheter peak pulmonary gradient (gradient between pulmonary artery and right ventricular body) before and immediately after PBV was 105 +/- 39 and 34 +/- 26 (P < .0001), respectively. The corresponding values for right ventricular pressure were 125 +/- 38 and 59 +/- 21 mm Hg (P < .0001), respectively. The infundibular gradient (in 43 patients) immediately after PBV was 42.9 +/- 24.8 (30-113) mm Hg, and it regressed at second catheterization to 13.5 +/- 8.3 mm Hg (P < .0001), whereas cardiac index improved from 2.68 +/- 0.73 to 3.1 +/- 0.4 L min(-1) m(-2) (P < .05). Doppler pulmonary gradient before PBV and at 1-year and long-term follow-up were 91 +/- 33 (range 36-200), 28 +/- 12 (range 10-60) (P < .0001), and 26 +/- 11 (range 7-60) mm Hg (P = .2), respectively. New mild pulmonary regurgitation was noted in 24 patients (28%) after PBV. Significant TR in 7 patients either regressed or disappeared after PBV. CONCLUSIONS Long-term results of PBV in adults are excellent. Severe infundibular stenosis and severe TR regressed after successful PBV. Therefore, PBV should be considered as the treatment of choice for adult patients with valvular pulmonary stenosis even in the presence of severe infundibular stenosis or severe TR.

Abstract
BACKGROUND This study was performed to determine independent predictors of long-term outcome after percutaneous balloon dilation of congenital pulmonary valve stenosis. Smaller follow-up series of patients after balloon pulmonary valvuloplasty have shown inconsistent results regarding the independent relation between prognostic factors and long-term outcome, as many patient selection and technical factors are correlated. METHODS AND RESULTS Follow-up data were obtained for 533 patients from 22 institutions at up to 8.7 years after an initial balloon pulmonary valvuloplasty. Patients were grouped based on defined long-term outcomes, and the independent effects of patient selection and technical factors were sought in multivariate statistical analyses. At follow-up, 23% of patients were noted to have an outcome judged to be suboptimal because of either a residual right ventricle to pulmonary artery peak systolic gradient of > or = 36 mm Hg or further treatment of pulmonary stenosis requiring repeat balloon pulmonary valvuloplasty or surgical therapy. Significant independent predictors of a suboptimal long-term outcome included an earlier study year of the initial valvuloplasty (adjusted odds ratio, 0.71 per consecutive year), a small valve hinge point diameter (0.81 per 1-mm increase), and a higher immediate residual gradient (1.32 per 10 mm Hg increase). A smaller ratio of balloon to valve hinge point diameter significantly predicted suboptimal outcomes for patients with valve morphologies classified as typical (0.52 per 0.1 increase in ratio) and complex (primarily postsurgical valvotomy, 0.43) but not for patients with dysplastic (0.95) or combined morphologies (dysplasia with commissural fusion, 1.01). Patient age, the presence of Noonan's syndrome or associated cardiac lesions, pre-balloon valvuloplasty hemodynamic parameters, and the use of a simultaneous double-balloon technique did not independently predict follow-up outcomes. CONCLUSIONS Accurate prognostication after balloon pulmonary valvuloplasty depends on the careful determination of valvar anatomy. The use of an appropriate ratio of balloon to valve hinge point diameter in the setting of typical valve morphology will optimize the chance of long-term success.

Abstract
The role of transcatheter methods in the management of pulmonary outflow tract obstruction are discussed in this review. Balloon pulmonary valvuloplasty for relief of isolated pulmonary valve stenosis has been successfully used by many investigators and is the procedure of choice for the management of these lesions. Supravalvar pulmonic stenosis, if discrete, can be relieved by balloon dilatation. Cyanotic children with interatrial right-to-left shunts secondary to severe valvar pulmonary stenosis respond in a manner similar to that observed with isolated pulmonary valve stenosis. In these patients, balloon valvuloplasty is the treatment of choice and may be corrective in most patients. In patients with interventricular right-to-left shunting secondary to pulmonary outflow tract obstruction and in patients with narrowed BT shunts, balloon dilatation may be an effective palliative procedure in a substantial proportion of patients obviating the need for an initial or second palliative shunt. Balloon dilatation is recommended if the patient's size or cardiac anatomy make them unsuitable for safe total surgical correction. In patients with pulmonary atresia, either initial opening of the atretic pulmonary valve by laser or by surgery with subsequent balloon dilatation are potentially beneficial in reducing the total number of surgical procedures that these children are likely to require. However, further clinical trials are needed before their general use.

Abstract
OBJECTIVES The present study was designed to establish possible predictors of unfavorable outcome in infants with pulmonary valve stenosis. BACKGROUND Balloon pulmonary valvuloplasty is the treatment of choice for typical pulmonary valve stenosis. Patients with dysplastic valves may be less suitable candidates for this procedure because they have morphologic abnormalities of the complex valve-anulus-trunk that cause the obstructive phenomenon. METHODS Twenty-five children (mean age +/- SD 1.1 +/- 0.7 years) with normal anulus diameter underwent balloon pulmonary valvuloplasty using a balloon/anulus ratio of 1.2 +/- 0.11. From the lateral view of a right ventricular angiogram, the following variables were quantified and scored: A, supravalvular narrowing; B, texture of the valve surface; C, diastolic deformity of the Valsalva sinuses; D, trunk/anulus ratio; E, systolic valve motion; and F, presence of a contrast jet. Paired t test, stepwise multivariate correlation with "dummy" variable methods were applied for both hemodynamic and valve-anulus-trunk determinations. RESULTS The right ventricular-pulmonary artery gradient decreased from 66 +/- 21 (range 40 to 120) to 24 +/- 11 (range 10 to 50) mm Hg (p less than 0.001), whereas the right ventricular systolic pressure decreased from 89 +/- 20 (range 60 to 130) to 48 +/- 15 (range 30 to 80) mm Hg (p less than 0.001). Only variables A, B and D had significant influence in a percent reduction in right ventricular pulmonary artery gradient (R2 0.94, SEE 5.7; p less than 0.001). A score greater than or equal to greater than 4 obtained by adding the values from these three variables was correlated with poor outcome. CONCLUSIONS These data show that there is an adequate relation between scores and outcome. We conclude that children less than 2 years old with pulmonary valve stenosis and a score greater than or equal to 4 should not be candidates for balloon pulmonary valvuloplasty.

Abstract
In this review, the role of transcatheter methods in the management of cyanotic congenital heart defects is discussed. In patients with interventricular right-to-left shunting secondary to pulmonary outflow tract obstruction (most commonly tetralogy of Fallot), balloon dilatation may be an effective palliative procedure in a substantial proportion of patients, obviating the need for a palliative shunt. We would recommend this if the patient's size or cardiac anatomy makes that patient an unsuitable candidate for safe total surgical correction. Infundibular myectomy with atherectomy catheter in tetralogy of Fallot patients may become a useful adjunct in the management of these infants. Cyanotic children with interatrial right-to-left shunt secondary to severe valvar pulmonary stenosis respond to balloon pulmonary valvuloplasty in a manner similar to that seen with isolated pulmonary valve stenosis. In these patients, balloon valvuloplasty is the treatment of choice and may be corrective in most cases. In patients with a narrowed Blalock-Taussig shunt, balloon angioplasty may improve pulmonary oligemia and systemic arterial hypoxemia and may obviate the need for a second systemic-to-pulmonary artery shunt. Balloon angioplasty is recommended if the patient's cardiac defect is not amenable to surgical correction at a low risk either because of the size of the patient or because of the complexity of the cyanotic heart defect. In patients with pulmonary valve atresia, initial opening of the atretic pulmonary valve by either laser or surgery with subsequent balloon dilatation is potentially beneficial in reducing the total number of surgical procedures that these children are likely to require. However, further clinical trials are needed prior to their general use.

Abstract
During a 2 1/2-year period, staged procedures of transventricular closed pulmonary valvotomy followed by balloon valvuloplasty were attempted in 12 babies with pulmonary atresia and an intact ventricular septum. All babies immediately underwent valvotomy when echocardiography revealed a tripartite right ventricle with adequate inflow and outflow dimensions and without sinusoidal-coronary arterial fistulas. After valvotomy, the overall mortality rate was 25% (3/12), but the only surgical death (1/12, 8%) was due to failure to establish continuity between the right ventricular cavity and the pulmonary trunk. The other 2 babies died of neonatal complications after successful valvotomy. Angiocardiography performed 5 to 18 months after valvotomy documented substantial growth of the right ventricular inflow and outflow dimensions in the 9 survivors. Twelve balloon dilation procedures were then performed in 7 babies. All except 1 achieved a significant drop in the right ventricular to left ventricular peak systolic pressure ratio (0.96 +/- 0.40 to 0.56 +/- 0.28; p less than 0.01). Balloon valvuloplasty was not required in 1 baby and failed in the other, who then underwent successful right ventricular outflow tract reconstruction. After these staged procedures, follow-up at 1 month to 20 months (mean follow-up, 14.8 months) revealed resting cyanosis in 3 babies, which was related to severe residual infundibular stenosis (55 mm Hg) in 1 and a subnormal tricuspid valve annulus in 2. The remaining 5 babies (including 1 who required no valvuloplasty) were active and pink (saturation greater than 97%) and had a mean Doppler estimated gradient of 19 mm Hg (range, 8 to 36 mm Hg) across the pulmonary valve.(ABSTRACT TRUNCATED AT 250 WORDS)
