Trisomy 18 also known as Edward’s syndrome‚ is the second most common aneuploidy in comparison to Down Syndrome or Trisomy 21. Edward’s syndrome is a chromosomal condition prompted by an error in cell division. This prognosis is very rare and as a result there are fewer than 20‚000 cases per year in the United States. Due to several life-threatening medical problems in correspondence to this demoralizing condition‚ many individuals with Edward’s syndrome die before birth or within their first month

Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it

Coronary Heart Disease (CHD) is a disease in which waxy substance called plaque builds up inside the coronary arteries. These arteries are used to supply oxygen-rich blood to your heart‚ so if they’re continuously blocked up‚ it can be very dangerous. If the flow of this oxygen-rich blood is reduced or blocked‚ a heart attack can occur. It is the number one cause of death in the United States for both men and women and although this type of disease mainly happens at an older age‚ it can happen

Unfortunately‚ about 50% of babies born with Down syndrome today have heart defects‚ which is a much higher percentage in comparison to the 1% of children born without Down syndrome who have heart defects (www.downsyndrome.about.com). The most common heart defect seen in infants with Down syndrome is an AV canal (atrioventrucular septal defect). There are three other less common heart defects seen in infants

Perimembranous Ventricular Defect A defect in the ventricular septum‚ the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum creating one common ventricle. Perimembranous VSDs are located in the left ventricle outflow tract beneath the aortic valve. They are the most common VSD subtype in the United States‚ occurring 75-80% of cases. Defects may extent into adjacent portions of the ventricular
