Diagnosis
The patient was diagnosed with recurrence of the sub­valvular membrane, signifi cant left ventricular outfl ow tract obstruction, severe aortic regurgitation, and moderate tricuspid regurgitation.
Comment
This membrane produced a systolic gradient of 60 mmHg and severe aortic regurgitation. Consequently, redo surgery was recommended for the patient. Additionally, the patient’s
tricuspid regurgitation was moderate and tricuspid annulus was 35 mm; therefore, tricuspid annuloplasty, in conjunction with subvalvular web resection and aortic valve replacement, was recommended [ 23 ].

Diagnosis
The patient was diagnosed with a bicuspid aortic valve, severe aortic regurgitation, mild left ventricular dilation, and normal systolic function.
Comment
The patient had a negative exercise tolerance test and a left ventricular ejection fraction of greater than 50 %. Accordingly, close follow-up and prophylaxis for infective endocarditis were recommended for him.
Lesson
1. The most common form of the bicuspid aortic valve is due to the fusion of the left and right coronary cusps (70–80 %).
2. The diagnosis of the bicuspid aortic valve is made in systole.
3. The bicuspid aortic valve is associated with aortopathy and the dilation of the aortic root and the ascending aorta [ 23 , 36 ].

A 20-year-old man presented with syncopal attack of 1-year duration. Physical examination revealed a systolic ejection murmur and a holodiastolic murmur at the left
sternal border and the aortic area. Echocardiography showed severe aortic insuffi ciency and the dilation of the ascending aorta.

Diagnosis
The patient was diagnosed with a bicuspid aortic valve, severe aortic regurgitation, and aortic root dilation. The bicuspid aortic valve was due to the fusion of the left and right coronary cusps.
Comment
The patient was referred for surgery. Because the sinus of Valsalva was approximately 42–43 mm, a computed tomography scan was recommended for a further evalua­tion of the ascending aorta. A sinus of greater than or equal to 45 mm would have mandated the Bentall operation [ 23 , 36 ].

A 46-year-old man presented with recent dyspnea on exer- tion (functional class II). Physical examination showed a systolic ejection murmur and a holodiastolic murmur at the left sternal border. Transthoracic echocardiography revealed that the aortic valve area was 1.1 cm

Diagnosis
The patient was diagnosed with bicuspid aortic valve, severe aortic stenosis, dilation of the ascending aorta (up to 50 mm), and mild mitral stenosis due to the extension of calcifi cation to the anterior mitral leafl et.
Comment
With respect to the patient’s severe valvular aortic stenosis and dilation of the ascending aorta up to 50 mm, the Bentall operation was recommended.
Lesson
In the bicuspid aortic valve, aortic root replacement at the time of aortic valve replacement is indicated with an aortic dimension of greater than 45 mm. In the absence of the aortic valve disease, aortic root replacement is recommended with an aortic dimension of greater than 50 mm [ 23 , 36 ].

A 26-year-old woman presented with dyspnea on exertion (functional class III) of recent duration. She was a known case of aortic regurgitation since 13 years old and had deliv­ered one child 2 years previously without complications.
Transthoracic echocardiography showed severe left ventricu­lar dilation and normal systolic function. The left ventricular ejection fraction was about 55 %.
