Cardiovascular Risks

TURNER SYNDROME
Turner syndrome is a genetic condition that only affects biological females, occurring when one of a female’s X chromosomes is fully or partially missing. Turner syndrome can disrupt many parts or functions of the body, but the primary characteristics include short stature,infertility, as well as some physical characteristics.
The missing X chromosome can commonly cause delays in development from an early age. Females with Turner syndrome may grow noticeably slower compared to peers and have little to no periods, provided they aren’t on estrogen supplements. Other known physical characteristics of Turner syndrome are webbed neck, broad chest, and low set ears. All of these characteristics are main causes of concern for those with Turner syndrome, and they may focus on fixing or improving them with doctors through various treatments. However, there are other risks that may be harmful if individuals affected do not consider them.
CARDIOVASCULAR HEALTH
Cardiovascular health is the umbrella term used to refer to health-related things in terms of the cardiovascular system. Blood pressure, heart health, blood vessel health, and common heart diseases are all part of cardiovascular health. Since the cardiovascular system allows our entire body to receive enough oxygen and nutrients, poor cardiovascular health can harm multiple bodily systems at once. These harms can be both fatal and nonfatal.
CARDIOVASCULAR HEALTH RISKS IN TURNER SYNDROME
Unfortunately, the missing X chromosome in individuals with Turner syndrome causes them to be at a higher risk for cardiovascular conditions. These individuals may have both congenital and acquired heart conditions. Some of the most common congenital heart abnormalities in Turner syndrome are bicuspid aortic valve, thoracic aortic aneurysm, coarctation of the aorta, and partial anomalous pulmonary venous connection (PAPVC). These cardiovascular conditions make individuals with Turner syndrome more susceptible to experiencing other developed difficulties such as stroke, high blood pressure (hypertension), aortic dissection, heart attack (myocardial infarction), and some pregnancy-related conditions. These include pre-eclampsia and various other conditions, with Turner Syndrome patients at an elevated risk compared to average individuals without Turner syndrome.
While most of these conditions are related to the aorta, they affect the aorta and the cardiovascular system as a whole in different ways. The aorta is the largest artery of the heart and it distributes freshly oxygenated blood all over the body. When the aorta is harmed, it can directly impair the body’s ability to deliver oxygen to parts of the body. One condition common in Turner syndrome that affects the aorta is bicuspid aortic valve, which is when the aortic valve of the heart has two (rather than three) flaps, called cusps. The cusps make sure blood is flowing in the right direction, so when one of them is missing, blood can leak and the aorta may become enlarged. This can cause some chest pains and difficulty with breathing, alongside increased risk of more serious heart conditions later on. Another condition related to the aorta is thoracic aortic aneurysm, which is the widening or bulging of the aorta. This usually happens when the aortic wall is weak, and can therefore show up as chest and back pain, coughs, and shortness of breath. Eventually, the weak aortic wall and the huge bulge can cause a dissection, which is a medical emergency and can become fatal if not treated in time. Similarly, coarctation of the aorta, also called aortic coarctation, is the narrowing of part of the aorta. This usually causes hypertension in many individuals with the condition due to the insufficient space that blood has to flow through. Since this also inhibits enough oxygenated blood from flowing to the body, symptoms may be similar to the other two conditions discussed above, with severe cases in babies including trouble feeding, heavy sweating, irritability, and blue or gray skin. In certain cases, coarctation of the aorta may occur with bicuspid aortic valve and thoracic aortic aneurysm, requiring extensive treatment for all three conditions.
The other common congenital condition that doesn’t directly occur in the aorta is partial anomalous pulmonary venous connection (PAPVC). PAPVC, also known as partial anomalous pulmonary venous return (PAPVR), is a condition where some, but not all, of the pulmonary veins from the lungs attach to the wrong place. Normally, oxygenated blood flows from the lungs to the left atrium of the heart to be pumped to the upper body. However, with PAPVC, the veins are attached to the right atrium instead and some of the oxygenated blood ends up going back to the lungs. This gives the right atrium an unnecessary extra load which can then cause swelling in the right chambers of the heart. These effects can cause some trouble breathing or fatigue, but sometimes the condition goes unnoticed.
There are also some rarer cases of some less common congenital cardiovascular conditions in individuals with Turner syndrome. These conditions include hypoplastic left heart syndrome (HLHS), coronary anomalies, dextrocardia, ventricular septal defect (VSD), and atrial septal defect (ASD). Even though these are extremely unlikely to occur, it is important that individuals with Turner syndrome remain aware of their overall risks with cardiovascular diseases so that they can recognize signs and get the right treatment.
CONCLUSION
Turner syndrome, a genetic condition in females associated with a missing or partially missing X chromosome, comes with extra cardiovascular health risks for individuals affected. While most heart conditions discussed can happen to anybody, they are much more common and likely to appear in individuals with Turner syndrome. Many of these diseases have genetic causes and can cause acquired diseases. It is absolutely crucial that individuals with Turner syndrome remain as aware of these risks as their other characteristics because they all affect their overall bodily health and the treatments they need to lead an independent life.
