Despite the development of non-invasive tools of investigations for congenital heart diseases (CHDs), still the role of diagnostic cardiac catheterization (DCC) cannot be undermined. The study aimed to analyze the clinical profile of indicated CHDs cases at our center for DCC to evaluate the contribution of DCC in patients’ management plans.

Material and methods:
The study checked files of cases performed DCC between 2011 and 2012 at the pediatric catheterization unit of Alexandria University Children’s Hospital by the same operator. Demographic, laboratory and hemodynamic data were collected and analyzed.

Files of 61 children were included in the study. They were grouped into: group I (GI) (n = 25) with pulmonary hypertension (PH), and group II (GII) (n = 36) cases with obstructive pulmonary artery diseases. For the PH group, ventricular septal defect (VSD) was the most common (55%), and patients’ outcome plans were based on angiography – operable subgroup GI-A: (84%) (n = 21) and non-operable (16%) GI-B: (4% inoperable, 12% recommended for sildenafil). GI-B cases were significantly older, with higher PVRI and PVRI/SVRI (3.62, 0.68, p = 0.002) compared to GI-A (0.89, 0.23, p = 0.002, respectively). For group II, tetralogy of Fallot (TOF) was predominant (60%) among the disease spectrum, and the McGoon ratio ranged from 0.7 to 3.2 (median: 1.8). Outcome for GII: 63% operable, 25% shunt, 12% stent. Only pulmonary atresia cases showed a significant difference in the unmatched plans between echocardiography and catheterization reports (χ2 = 7.438, p = 0.023).

Diagnostic cardiac catheterization had a positive contribution for determination of the management plans for more than 84% of cases. The utility of pediatric cardiac catheterization in diagnosis should be adjusted according to the local needs of every cardiac center.
