Critical congenital heart disease (CCHD) refers to a group of life-threatening heart conditions that affect newborns and infants. These conditions are present at birth and involve structural abnormalities in the heart or major blood vessels. CCHD can cause serious problems with blood flow to the body and may result in severe health complications or even death if not detected and treated early.

There are several different types of CCHD, including Tetralogy of Fallot, Transposition of the Great Arteries, and Hypoplastic Left Heart Syndrome. These conditions are often associated with genetic factors, and testing for specific genetic mutations or abnormalities can help identify individuals at higher risk for CCHD. Genetic testing can also provide valuable information about the causes and development of these diseases, contributing to ongoing research and clinical trials aiming to improve the diagnosis, treatment, and management of CCHD.

In addition to genetic testing, other diagnostic methods and tools are used to identify and evaluate patients with CCHD. These may include clinical examinations, imaging tests, blood tests, and cardiac catheterization. The information gathered from these tests helps healthcare professionals develop appropriate treatment plans and provide necessary support and resources to patients and their families.

Managing CCHD requires a multidisciplinary approach involving various medical specialists, including pediatric cardiologists, cardiothoracic surgeons, and genetic counselors. Ongoing research, advocacy efforts, and support from patient associations and other resources play a vital role in raising awareness about CCHD, promoting early detection and timely intervention, and improving the overall care and outcomes for individuals with this rare, but critical, heart disease.
