BACKGROUND
A 79-year-old female patient with past medical history of chronic myeloid leukaemia, presented to the outpatient cardiology clinic with shortness of breath (NYHA class 3) and fatigue.
INVESTIGATION
Echocardiography (ECG) and multislice computed tomography (MSCT).
DIAGNOSIS
Severe calcified aortic valve stenosis by echocardiography. Logistic EuroSCORE 10.3. Porcelain aorta by multislice computed tomography (MSCT).
TREATMENT
Transcatheter aortic valve implantation (TAVI) with an 18 Fr Medtronic-CoreValve system (Medtronic Inc., Minneapolis, MN, USA) using a right transfemoral arterial approach.
背景
一位 79 岁女性患者，既往有慢性髓性白血病病史，因呼吸困难（纽约心脏病协会心功能分级 3 级）和疲劳到心内科门诊就诊。
检查
超声心动图（ECG）和多层螺旋 CT（MSCT）。
诊断
超声心动图提示严重钙化性主动脉瓣狭窄。Logistic EuroSCORE 10.3。多层螺旋 CT（MSCT）提示主动脉呈瓷样改变。
治疗
