RESUMEN
To study the frequency, prevalence, clinical presentation, management and out come of inflammatory heart diseases [IHD] in Lebanese children. Prospective survey of a group of children carriers [or at high risk] of an IHD [n: 156] recorded over a period of six years, between May 1[st], 1999, and April 30[th], 2005, at the National Register of Paediatric and Congential Heart Disease, Lebanese Society of Cardiology. The diagnosis was confirmed in all cases by echocardiography. Cases related to cardiac surgery were excluded. Acute rheumatic fever [ARF] is the most frequent pathology: 35.9%, followed by Kawasaki disease [KD]: 24.4%, dilated cardiomyopathy [DCM]: 22.4% pericardial effusion: 10.9% and finally infective endocarditis [IE]: 6.4%. There is a seasonal predominance for the ARF and KD during fall and early spring. Consanguineous marriage of first degree dosen't seem to be a factor predisposing for ARF and KD. ARF with carditis benefited from steroids with partial to total regresstion in 41/45 patients [91%], two patients under went valve repair or replacement, another patient died from severe pancarditis. All children affected with KD [except 2 cases] received IV immunoglobulins [2 g/kg, single dose], and coronary aneurysms were observed in 2 patients [5.3%]. Patients with DCM in whom there was a strong suspicion of viral myocarditis, were treated medically with complete recuperation of the cardiac function in 88% of cases. Among the patients with pericardial effusion, 3 needed urgent drainage because of a tamponnade. A child with IE was operated of his mitral valve and another one with cerebral palsy had a fatal outcome. No case of cardiac disease associated with HIV infection was found. In Lebanon, ARF remains the main cause of IHD during childhood, before KD. Currently, non-surgical treatments are highly efficient. Delayed diagnosis increased morbidity. Efforts are necessary for early recongnition and primary prevention

We evaluated our immediate and midterm results of balloon dilation of critical valvular aortic stenosis in 15 consecutive neonates. Balloon dilation was attempted in 15 neonates at a mean age of 14 days. Three patients [20%] had associated left heart hypoplasia. Balloon dilation could be performed in 14 out of the 15 neonates [93.3%]. The average immediate maximal gradient reduction was 80 +/- 26%. The immediate mortality rate was nil, but 7 deaths [46%] occurred afterwards all not related to the dilation. Moderate to severe aortic regurgitation was noted in 7/14 [50%] of the dilated neonates but none has necessitated reintervention. At a mean follow-up of 11.5 months, survival and freedom of reintervention rates were respectively 40% and 50%. At last follow-up, 87.5% of the survivors were asymptomatic. This study confirms that dilation of aortic stenosis in neonates is effective, with encouraging immediate success but still disappointing short and midterm results
