Role of 128 slice multi-detector Computed tomography angiography in Evaulation of congenital cyanotic Heart diseases - a hospital based one Year cross sectional study

Abstract

Background and objectives: Cyanotic heart disease refers to a type of congenital heart defect that causes cyanosis, a bluish discoloration of the skin and mucous membranes. This condition occurs because the heart defect allows oxygen-poor blood to mix with oxygen-rich blood, resulting in decreased oxygen levels in the bloodstream. Cyanotic heart defects often involve structural abnormalities in the heart that affect how blood flows through the heart and to the lungs. Some most common cyanotic heart defects include: 1. Tetralogy of Fallot: 2. Transposition of the Great Arteries 3. Tricuspid Atresia 4. Total Anomalous Pulmonary Venous Return (TAPVR) 5. Truncus arteriosus Cyanotic heart defects typically require surgical intervention early in life to improve blood flow and oxygenation. Surgery aims to correct the structural abnormalities or to temporarily improve blood flow until definitive repair can be performed. The long-term outlook for individuals with cyanotic heart disease depends on the specific defect, the timing of intervention, and any associated complications. Advances in surgical techniques and medical management have significantly improved outcomes for many patients with these conditions. xiv The objective of the research was to evaluate the sensitivity, specificity, and accuracy of CT scan in detecting diverse cardiovascular abnormalities in individuals with complex congenital heart disease. It also sought to gather additional information for pre-operative patients with inconclusive results on echocardiography. Furthermore, the study aimed to compare the findings of multi-detector computed tomography angiography (MDCTA) with 2D-echocardiography to accurately outline the morphological characteristics of the cardiovascular system. The goal was to determine whether MDCT could potentially replace diagnostic echocardiography for assessing complex CHD.
