The Silent Heart Condition Affecting One in Fifty People
Hundreds of thousands of individuals across the United Kingdom are living with a potentially serious heart condition without any awareness of its presence. Medical experts reveal that between one and two percent of the population, equating to approximately one in fifty people, are born with a bicuspid aortic valve (BAV). This congenital heart defect often remains asymptomatic for decades, with many cases not diagnosed until middle age.
Understanding Bicuspid Aortic Valve
The Leeds Teaching Hospitals NHS Trust provides crucial insight into this condition. Normally, the aortic valve consists of three cusps or leaflets that regulate blood flow from the heart's left ventricle to the aorta. However, in individuals with BAV, this valve has only two cusps instead of the typical three. While these valves can function adequately throughout life, they possess a tendency to become narrow or develop leaks as people age.
"This is usually an incidental finding," explains the trust. "These valves can function very well throughout life but do have a tendency for the valve to become narrow and/or leak as people get older."
Additionally, people with bicuspid aortic valves frequently experience abnormalities in the aorta itself, causing this major blood vessel to become stretched over time.
Diagnosis and Monitoring Requirements
Diagnosing BAV involves a relatively simple procedure: an ultrasound scan of the heart known as an echocardiogram. Once identified, the condition requires regular monitoring every few years in outpatient departments to ensure the valve continues functioning properly and doesn't develop leaks or narrowing.
"Sometimes the main blood vessel, the aorta may stretch (dilate) over years with the risk of a tear once it gets beyond a certain size," warns the Leeds Teaching Hospitals. This potential complication underscores the importance of consistent cardiologist supervision through regular scans of both the valve and aorta.
Significant Health Risks and Preventative Measures
Patients diagnosed with bicuspid aortic valve face particular risks, most notably endocarditis – a life-threatening heart infection. The Leeds Teaching Hospitals Trust emphasizes that endocarditis may originate from dental or gum infections, making regular dental visits every six to twelve months essential for prevention.
The trust specifically advises against procedures that break the skin, including:
- Tattooing
- Body piercing
- Cosmetic treatments like eyebrow microblading
- Botox injections
- Dermal fillers
These activities carry a small but significant risk of infection that could potentially spread to the heart.
For children with bicuspid valves who don't exhibit narrowing or leakage, the trust recommends normal activity levels without restrictions, unless other associated heart problems exist.
Recognizing the Symptoms
The Aortic Dissection Charitable Trust highlights that BAV symptoms often go unnoticed or are mistakenly attributed to other conditions. In adults, potential indicators include:
- Fatigue – frequently overlooked as a common sign
- Chest discomfort – pain or discomfort in the chest area
- Dizziness or fainting – sudden, unexplained episodes
- Heart palpitations – uncomfortable awareness of heartbeat
- Shortness of breath – particularly noticeable during physical exertion
For children, symptoms may manifest differently:
- Easily fatigued – quicker to tire during play or activity
- Chest pain – uncommon but possible
- Fainting – sudden and unexplained episodes
- Pale skin – potentially indicating reduced blood flow
- Breathing difficulties – particularly noticeable during feeding for infants
The Serious Threat of Endocarditis
Endocarditis represents a particularly dangerous complication for those with BAV. This infection develops on heart valves or surrounding tissues and proves extremely difficult to treat, typically requiring extended hospital stays with intravenous antibiotics.
"Patients who develop endocarditis can be extremely unwell and often require heart surgery to remove the infected area," warns the Leeds Teaching Hospitals. "Sometimes people die from endocarditis."
Since the mouth serves as the most common source of bacteria causing endocarditis, maintaining excellent oral hygiene becomes paramount. Recommendations include:
- Brushing teeth twice daily with fluoride toothpaste
- Maintaining a healthy diet while avoiding sugary snacks and drinks
- Drinking plain water or milk between meals
- Seeking immediate dental care for toothaches or mouth infections
The Aortic Dissection Charitable Trust emphasizes that BAV frequently leads to valve-related diseases such as aortic regurgitation (where the valve fails to close properly, causing blood leakage) or aortic stenosis (where the valve narrows, affecting blood flow). Additionally, many with this condition experience aortopathy involving aortic dilation, which can progress to more severe complications including aortic aneurysm, dissection, and rupture.
With up to one in fifty people affected by this often-silent condition, increased awareness, regular monitoring, and preventative measures become essential components of maintaining cardiac health for those living with bicuspid aortic valve.
