“…[38][39][40] Guidelines for care have been established to optimize the complex management of individuals with NS. 11,41,42 Because vPS comprises a significant portion of CHD in the general population, it is important to ascertain which patients with vPS are most likely to have a syndromic diagnosis and thus require evaluation by genetics. Pulmonary valve dysplasia has been noted to occur more frequently (25%-35%) [43][44][45] in individuals with NS.…”

“…Up to 50% of patients with Noonan syndrome have an abnormal electrocardiographic pattern characterized by left axis deviation, an abnormal R/S ratio over the left precordial leads, and an abnormal Q wave. These findings are independent of underlying cardiovascular malformations [15]. Patients with Noonan syndrome need lifetime cardiac follow-up because left sided obstructive lesions may develop in adulthood and hypertrophic cardiomyopathy can develop at any age.…”

“…Hierbij is de aard van de ECG-afwijking echter niet altijd gerelateerd aan het onderliggende cardiale defect en kan een cardiaal defect zelfs afwezig zijn. 22 Bij de beoordeling van de ECG's hanteerden wij de normaalwaarden van Davignon.…”
