Which of the following is NOT a characteristic of congenital heart defects?

The understanding of congenital heart defects is paramount in recognizing their variability and implications. One of the main characteristics of congenital heart defects is that while they can lead to severe complications, not all cases are fatal. Many congenital heart defects can be managed effectively with medical treatments, lifestyle changes, and in some instances, surgical intervention. Advances in medical technology and surgical techniques have significantly improved outcomes for many patients with these conditions, enabling them to live full and healthy lives.

The presence of a heart murmur is a common indicator that prompts further investigation for congenital heart defects, as it often reflects turbulent blood flow associated with structural abnormalities in the heart. Diagnosis through an echocardiogram is a widely utilized method for visualizing heart structures and assessing any defects. Surgical intervention may be necessary for a variety of congenital heart conditions, depending on the severity and specific nature of the defect. Thus, recognizing that not all congenital heart defects are fatal is key in understanding the broader context of this medical field.
