About this study

Official title: Multidetector Cardiac Computed Tomographic Assessment of Cardiac and Extra Cardiac Vascular Anomalies Associated With Tetralogy of Fallot in Pediatric

Evaluation of cardiac and extra cardiac vascular defects associated with Tetralogy of fallot in pediatric patients, regarding frequency and types of anomalies with assesment of multidetector computed tomography diagnostic value.

Read the detailed description

Tetralogy of Fallot (TOF) is the most common complex cyanotic congenital heart disease (CHD), with a prevalence of 3.5-9%. Almost all pediatric patients born with TOF can now expect to survive to adulthood because of advances in its surgical treatment. In addition to the four diagnostic criteria of TOF that include ventricular septal defect, right ventricular hypertrophy with outflow tract obstruction, and overriding aorta, other extra-cardiac vascular anomalies are frequently coexist . These may involve pulmonary, aortic, and coronary arteries with or without valve abnormalities, aorto-pulmonary vessels, and vena cava connections, is crucial for surgeons in the formulation of surgical strategies. Trans-thoracic echocardiography (TTE) is the initial classical procedure done for these patients, as it can demonstrate heart structure and estimate intra-cardiac pressures, gradients, and contractile functions as well as blood flow direction across any heart defect and emphasizing coronary vessels integrity. However, many extracardiac vascular defects associated with different heart diseases cannot be detected accurately by TTE; consequently, heart catheterization with its invasive complications was widely used for confirming these abnormalities before surgery. Recently, the evolution of multi-slice or multi-detector computed tomography (MDCT) with its multi-planar information, lower doses of radiation, short scanning time, and easy availability suggested it to be a non-invasive reliable diagnostic method for detection of different malformations in pediatric patients with complex CHD. Thus, effective imaging modalities are required to provide a thorough preoperative anatomic description of the associated extracardiac vascular anomalies in pediatric patients with TOF in order to improve surgical planning and outcomes. In recent years, multi-detector computed tomography (MDCT) has become regarded as a reliable non-invasive tool for delineating various anomalies in patients with complex CHD. Few studies have focused on the preoperative evaluation of associated cardiac and extracardiac vascular anomalies in pediatric patients with TOF using MDCT, especially not large case series studies. In this study, we aim to investigate the diagnostic performance of MDCT for assessing associated cardiac and extracardiac vascular abnormalities in patients with TOF.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of cardiac and extra cardiac vascular anomalies associated with tetralogy of Fallot by MDCT and its repercussion on preoperative decision.

    The four main characteristics of TOF [ventricular septal defect, overriding aorta, right ventricular outflow tract (RVOT) obstruction, and right ventricular hypertrophy] and associated cardiac and extracardiac malformations will be analyzed and recorded using a sequential segmental approach. To compare the diagnostic performance of DSCT with that of TTE, we will categorize all the surgically confirmed associated cardiac and extracardiac vascular deformities into five groups, namely abnormal vena cava connection (AVCC), aortic artery and valve disorders, anomalies of the pulmonary artery and valve, deformities of the aortopulmonary vessels, and coronary artery anomalies (CAAs).

Questions about this trial

What is this clinical trial studying?

An observational study of Fallot Tetralogy, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 23 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of cardiac and extra cardiac vascular anomalies associated with tetralogy of Fallot by MDCT and its repercussion on preoperative decision. (time frame: within a year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Mar 2022.
