Angiography in the left ventricle at a 45/20 left anterior oblique projection/cranial was used to profile the PMVSD (fig-1).
The diameter of the PMVSD was measured at the largest diastolic phase, and an occluder was selected based on this measurement.
Among all 30 patients in which we attempted transcatheter closure of PMVSD, all patients (100%) were successfully treated by transcatheter intervention.
Different devices have been used to close PMVSD15, among which the Amplatzer PMVSD occluder and similar devices have been shown to cause few complications and yield good results16.
Indications for intervention in pmVSD include: (1) recurrent respiratory tract infections; (2) significant hemodynamic changes such as left chamber enlargement; (3) heart failure and developmental delay; (4) patient's weight >10 kg and age >2 years; (5) uncomplicated but significant pulmonary hypertension; and (6) absence of concomitant heart abnormalities warranting surgical repair concurrently.
A total of 395 patients (199 males) with pmVSD who fulfilled the inclusion criteria were enrolled in this retrospective study.
Logistic regression analysis was conducted to further determine the risk factors for arrhythmia associated with transcatheter closure of pmVSD. Arrhythmia was used as the dependent variable.
The incidence rate of arrhythmia after transcatheter closure of pmVSD is approximately 25.4% to 37.7%.
Most common cause of hemodynamically significant VSD in infants and children is Perimembranous ventricular septal defects (PMVSDs).
Transcatheter closure of multiple pmVSD with giant aneurysms using double devices is feasible and safe in selected patients.
From July 2012 to April 2016, four patients with multiple pmVSDs underwent transcatheter closure with double occluders successfully.
It is still a great challenge for cardiologists to transcatheter close multiple pmVSDs with giant aneurysm due to anatomic complexity and variation.[sup][1] Although some modified devices such as small-waist occluder may help cure this kind of disease, it still probably failed due to a significant RS.[sup][2] We made an attempt to close a giant aneurysmal VSD using more than one device.
