Postoperative Pulmonary Hemodynamics and Systemic Inflammatory Response in Pediatric Patients Undergoing Surgery for Congenital Heart Defects.

There is scarce information about the relationships between postoperative pulmonary hemodynamics, inflammation, and outcomes in pediatric patients with congenital cardiac communications undergoing surgery. We prospectively studied 40 patients aged 11 (8-17) months (median with interquartile range) with a preoperative mean pulmonary arterial pressure of 48 (34-54) mmHg who were considered to be at risk for postoperative pulmonary hypertension. The immediate postoperative pulmonary/systemic mean arterial pressure ratio (PAP/SAP, mean of first 4 values obtained in the intensive care unit, readings at 2-hour intervals) was correlated directly with PAP/SAP registered in the surgical room just after cardiopulmonary bypass ( = 0.

EXPRESS: Parameters associated with outcome in pediatric patients with congenital heart disease and pulmonary hypertension subjected to combined vasodilator and surgical treatments.

Management of pediatric pulmonary hypertension associated with congenital heart disease (PHT-CHD) is challenging. Some patients have persistently elevated pulmonary artery pressure (PAP) after cardiac surgery, an undesired condition that is difficult to predict. We investigated the value of clinical, hemodynamic, and histopathological data in predicting the outcome in a prospective cohort.

Repair of congenital heart disease with associated pulmonary hypertension in children: what are the minimal investigative procedures? Consensus statement from the Congenital Heart Disease and Pediatric Task Forces, Pulmonary Vascular Research Institute (PVRI).

Standardization of the diagnostic routine for children with congenital heart disease associated with pulmonary arterial hypertension (PAH-CHD) is crucial, in particular since inappropriate assignment to repair of the cardiac lesions (e.g., surgical repair in patients with elevated pulmonary vascular resistance) may be detrimental and associated with poor outcomes.

Capillary hemangiomatosis like-lesions in lung biopsies from children with congenital heart defects.

The morphological findings in the lung vessels of children with pulmonary arterial hypertension associated with uncorrected congenital cardiac shunts may be qualitatively and quantitatively assessed by lung biopsy in selected cases. Among 297 lung biopsies collected over a period of 11 years two cases were detected presenting the typical findings of pulmonary capillary hemangiomatosis, a rare disorder usually associated with pulmonary veno-occlusive disease. We report the clinical and histological findings and discuss about the impact of this unexpected and not-previously described associated lesion on the prognosis and on the therapeutic strategy in patients with pulmonary hypertension associated with congenital heart disease.

Identification of respiratory virus in infants with congenital heart disease by comparison of different methods.

Respiratory virus infections are the main cause of infant hospitalization and are potentially severe in children with congenital heart disease (CHD). Rapid and sensitive diagnosis is very important to early introduction of antiviral treatment and implementation of precautions to control transmission, reducing the risk of nosocomial infections. In the present study we compare different techniques in the diagnosis of respiratory viruses in CHD infants.

[Association of plastic bronchitis to protein-losing enteropathy after fontan operation].

We report an unusual case of association of plastic bronchitis (PB) to protein-losing enteropathy (PLE) in a girl of 4 years and 9 months of age with double inlet single left ventricle and ventriculoarterial concordance. submitted to total cavopulmonary surgery. with an intracardiac lateral tunnel at the age of three.

A computer-based matrix for rapid calculation of pulmonary hemodynamic parameters in congenital heart disease.

Background: In patients with congenital heart disease undergoing cardiac catheterization for hemodynamic purposes, parameter estimation by the indirect Fick method using a single predicted value of oxygen consumption has been a matter of criticism.

Objective: We developed a computer-based routine for rapid estimation of replicate hemodynamic parameters using multiple predicted values of oxygen consumption.

Materials And Methods: Using Microsoft® Excel facilities, we constructed a matrix containing 5 models (equations) for prediction of oxygen consumption, and all additional formulas needed to obtain replicate estimates of hemodynamic parameters.
