A 32-year-old woman, who had been followed up in our cen­ter for the previous 8 years, developed atypical chest pain. Physical examination showed a holosystolic murmur at the left sternal border.
Echocardiography revealed normal left ventricular and
right ventricular sizes as well as systolic functions, Qp/Qs of
1.3, peak pulmonary arterial systolic pressure of 35 mmHg,
and trivial aortic insuffi ciency.

Diagnosis
The patient was diagnosed with a doubly committed VSD.
Comment
Considering that the patient was asymptomatic and had a Qp/Qs of 1.3 and an upper limit of normal peak pulmonary arterial systolic pressure (35 mmHg), prophylaxis for infec­tive endocarditis and follow-up were recommended.

A 24-year-old man, who had previously undergone device closure for a ventricular septal defect (VSD) in our center,
was referred to our echocardiography laboratory for follow-up echocardiography. He was totally asymptomatic.

Diagnosis
The patient was diagnosed with a perimembranous VSD, which was successfully closed by device. No residual shunt or obstructive effect was seen on other organs.
Lesson
The perimembranous VSD can be closed by intervention. The rim to the aortic valve must be more than 2 mm [ 72 ]. Amplatzer VSD occluder membranous and muscular are available in sizes between 4 and 18 mm. Membranous occluder type extends 0.5 mm in the aortic end and 5.5 mm in the apical end on the LV side. Right ventricular disk is symmetric and extends 4 mm, and the length is 1.5 mm. Muscular VSD occluder extends 8 mm at the waist and the length is 7 mm [ 80 ]. Device size is chosen 1–2 mm larger than VSD size measured by echocardiography or angiography [ 72 ].
The possible complications of VSD device closure
include (1) complete atrioventricular block, (2) prolapse of aortic leafl ets and aortic regurgitation, and (3) embolization of device [ 72 ]. Tricuspid regurgitation severity improves fol­lowing membranous VSD closure [ 81 ].

sure effect by the VSD device closure ( arrow ) on the other organs. LA left atrium, LV left ventricle, RA right atrium, RV right ventricle

A 16-year-old male, completely asymptomatic with a history of surgery for ventricular septal defect (VSD) closure 2 years previously, was referred to us for follow-up echocardiogra­phy. Physical examination revealed a continuous murmur (grade IV/VI) at the left sternal border.
Echocardiography showed a normal left ventricular size
and systolic function and a normal right ventricular size and function.

Comment
Given the continuous fl ow, the following differential diagno­ses were considered for the patient:
1. Rupture of the sinus of Valsalva to the right ventricle
2. Fistula of the right coronary artery to the right ventricle (although this anomaly has a diastolic accentuation of fl ow, since the perfusion of the coronary arteries is domi­nated in diastole)
3. Low probability of the rupture of the VSD patch
Consequently, transesophageal echocardiography (TEE) was conducted to make a defi nite diagnosis.

Case 55 Residual Ventricular Septal Defect Post Surgery (Patch Closure)
173
Diagnosis
The patient was diagnosed with a large VSD following the fi rst surgery for VSD closure.
Comment
Given the pulmonary arterial systolic pressure of 50 mmHg and the absence of rim to the aortic valve, the patient was referred for VSD patch closure by surgery.
Lesson
The VSD fl ow is almost always systolic but there are rare cases with systolic and diastolic fl ow [ 82 , 83 ].
