Aortic stenosis Symptoms of aortic stenosis may include heart failure symptoms, such as dyspnea on exertion (most frequent symptom), orthopnea and paroxysmal nocturnal dyspnea, angina pectoris, and syncope, usually exertional. Medical signs of aortic stenosis include pulsus parvus et tardus, that is, diminished and delayed carotid pulse, fourth heart sound, decreased A2 sound, sustained apex beat, precordial thrill. Auscultation may reveal a systolic murmur of a harsh crescendo-decrescendo type, heard in 2nd right intercostal space and radiating to the carotid arteries. Aortic regurgitation Patients with aortic regurgitation may experience heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, and angina pectoris. In acute cases patients may experience cyanosis and circulatory shock. Medical signs of aortic regurgitation include increased pulse pressure by increased systolic and decreased diastolic blood pressure, but these findings may not be significant if acute. The patient may have a diastolic decrescendo murmur best heard at left sternal border, water hammer pulse, Austin Flint murmur, and a displaced apex beat down and to the left. A third heart sound may be present Mitral stenosis Patients with mitral stenosis may present with heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, chest pain, hemoptysis, thromboembolism, or ascites and edema (if right-sided heart failure develops). Symptoms of mitral stenosis increase with exercise and pregnancy On auscultation of a patient with mitral stenosis, typically the most prominent sign is a loud S1. Another finding is an opening snap followed by a low-pitched diastolic rumble with presystolic accentuation. The opening snap follows closer to the S2 heart tone with worsening stenosis. The murmur is heard best with the bell of the stethoscope lying on the left side and its duration increases with worsening disease. Advanced disease may present with signs of right-sided heart failure such as parasternal heave, jugular venous distension, hepatomegaly, ascites and/or pulmonary hypertension (presenting with a loud P2). Signs increase with exercise and pregnancy. Mitral regurgitation Patients with mitral regurgitation may present with heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, or pulmonary edema. On auscultation of a patient with mitral stenosis, there may be a holosystolic murmur at the apex, radiating to the back or clavicular area, a third heart sound, and a loud, palpable P2, heard best when lying on the left side. Patients also commonly have atrial fibrillation. Patients may have a laterally displaced apex beat, often with heave In acute cases, the murmur and tachycardia may be only distinctive signs. Tricuspid regurgitation Patients with tricuspid regurgitation may experience symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension. Signs of tricuspid regurgitation include pulsatile liver, prominent V waves and rapid y descents in jugular venous pressure. Auscultatory findings include inspiratory third heart sound at left lower sternal border (LLSB) and a blowing holosystolic murmur at LLSB, intensifying with inspiration, and decreasing with expiration and Valsalva maneuver. Patients may have a parasternal heave along LLSB. Atrial fibrillation is usually present in patients with tricuspid regurgitation
