As a result of advances in cardiac surgery and interventional treatment, cardiac catheterisation is now being performed more often in neonates and small infants. In these patients the vascular approach is a major concern because of limited vascular access and the potential for vascular damage.1,2 For these reasons, the miniaturisation of diagnostic catheters and interventional tools to preserve vascular access in small patients is of vital importance.

The aim of our study was to assess the feasibility and safety of diagnostic and interventional procedures performed in small infants using 3 French sheaths and catheters, and to evaluate their results.


From January 2001 to December 2002 we performed 11 diagnostic and five interventional procedures in 15 infants, utilising 3 French sheaths and catheters. Inclusion criteria were: need for arterial catheterisation in patient weighing ⩽ 4 kg, or need for venous catheterisation in patient < 3 kg. The median age and weight of the patients were 7 days (range 1–180 days) and 2.8 kg (range 2–4 kg), respectively. Diagnosis and type of procedure are listed in table 1.
