Entire Body System
- Fever
People with infective endocarditis may develop fever. If aortic stenosis or aortic regurgitation develops, the person may tire easily, and have shortness of breath, fainting, awareness of heartbeats (palpitations), and chest pain. [merckmanuals.com]
- Pain
If aortic stenosis or aortic regurgitation develops, the person may tire easily, and have shortness of breath, fainting, awareness of heartbeats (palpitations), and chest pain. [merckmanuals.com]
- Fatigue
Symptoms depend on the type of complication and can include fever in infective endocarditis or dyspnea, fatigue, syncope, palpitations, and exercise intolerance due to valvular regurgitation or stenosis. [merckmanuals.com]
- Asymptomatic
Circulation 119(6):880–890, 2009. doi: 10.1161/CIRCULATIONAHA.108.795401 Children with bicuspid aortic valve may be asymptomatic if there is little or no valve dysfunction. [merckmanuals.com]
Respiratoric
- Dyspnea
Symptoms depend on the type of complication and can include fever in infective endocarditis or dyspnea, fatigue, syncope, palpitations, and exercise intolerance due to valvular regurgitation or stenosis. [merckmanuals.com]
Gastrointestinal
- Regurgitation
If aortic stenosis or aortic regurgitation develops, the person may tire easily, and have shortness of breath, fainting, awareness of heartbeats (palpitations), and chest pain. [merckmanuals.com]
Cardiovascular
- Palpitations
If aortic stenosis or aortic regurgitation develops, the person may tire easily, and have shortness of breath, fainting, awareness of heartbeats (palpitations), and chest pain. [merckmanuals.com]
- Ejection Murmur
Examination reveals an early systolic click, a systolic ejection murmur and, if aortic regurgitation is present, a diastolic decrescendo murmur. Echocardiography Diagnosis is by physical examination findings and echocardiography. [merckmanuals.com]
- Chest Pain
If aortic stenosis or aortic regurgitation develops, the person may tire easily, and have shortness of breath, fainting, awareness of heartbeats (palpitations), and chest pain. [merckmanuals.com]
- Heart Murmur
Doctors suspect a bicuspid aortic valve if they hear a heart murmur or a clicking sound during an examination with a stethoscope. Echocardiography is then done to confirm the diagnosis. [merckmanuals.com]
Treatment
Balloon dilation or surgical repair Treatment of bicuspid aortic valve is indicated if severe valve dysfunction develops and if symptoms occur. Treatment consists of balloon dilation or surgical repair of stenotic valves. [merckmanuals.com]
