Low weight as an independent risk factor for adverse events during cardiac catheterization of infants

Background Studies have documented the importance of procedure type and hemodynamic variables on the incidence of procedure related adverse events (AE) after cardiac catheterization. However, little is known about the impact of low weight on the incidence and severity of AE. Methods: Data were prospectively collected using a multicenter registry (C3PO). Infants <1 year were divided into four weight categories: <2 kg, 2–3 kg, 3–5 kg, ≥5 kg....
