Diagnosis Etiology and pathology Pathophysiology e Clinical manifestation ° Physical Findings e Laboratory Examination Differential Diagnosis Treatment 复旦大学附属中山医院 Zhongshan Hospital, Fudan University @
Diagnosis • Etiology and pathology • Pathophysiology • Clinical manifestation • Physical Findings • Laboratory Examination • Differential Diagnosis • Treatment
Key Concepts o Echocardiography remains the gold standard for diagnosis and follow up patients with valvular heart disease. Stenotic valvular lesions can be monitored clinically until symptoms appear ● Regurgitant valvular lesions require careful echocardiographic monitoring for left ventricular function and may require surgery even if no symptoms are present 复旦大学附属中山医院 Zhongshan Hospital, Fudan University @

Rheumatic fever results in four forms of fusion leading to stenosis: Commissural Cuspal Chordal Combined o mitral valve cusps fuse at the their edges o fusion of the chordae tendineae results in thickening and shortening of these structures 复旦大学附属中山医院 Zhongshan Hospital, Fudan University @

Calcification of the valve immobilizes the leaflets and narrows the orifice lead to narrowing of the valve(fish mouth) e dilated left atrium (LA) o Thrombus frequently arise from LA in patients with atrial fibrillation(AF) Other causes: congenital,- malignant carcinoid, SLE, Amyloid, etc. 复旦大学附属中山医院 Zhongshan Hospital, Fudan University @
