Magnetic resonance imaging roadmaps of cardiac structures were obtained from miniature swine with spontaneous vsd and registered with live x ray using external fiducial markers. Nowadays percutaneous trascatheter closure is considered feasible therapy for vsd compared to closure by surgery which carries the risks of complete atrio ventricular block cavb about 2 9 5 7 and cardio pulmonary 8 10.

Recently perventricular device closure of isolated vsds has become increasingly popular especially in china.

Vsd closure device x ray. In vsd closure surgery the defect usually requires a patch of some sort. It involves crossing the vsd retrograde from the left to right ventricle retrieving a guidewire from the right ventricle side positioning a delivery sheath for the closure device into the left ventricular apex and device deployment. Early and mid term results.

Heart vessels 2012 27 398 404. A large vsd may also show features of pulmonary arterial hypertension pulmonary edema pleural effusion and increased pulmonary vascular markings. Wei y wang x zhang s hou l wang y xu y et al.

This means that the immune system should not react to the material. Often this material is either dacron or ptfe. Larger vsds may show cardiomegaly particularly left atrial enlargement although the right and left ventricle can also be enlarged.

We compared antegrade xfm guided vsd crossing with conventional retrograde x ray guided crossing for repair. Catheter based closure of ventricular septal defects vsd is technically demanding. Transcatheter closure of perimembranous ventricular septal defects vsd with vsd occluder.

Frontal and lateral asd closure device. We compared antegrade xfm guided vsd crossing with conventional retrograde x ray guided crossing for repair. However percutaneous device closure requires x ray exposure to both patients and doctors 13 15.

We hypothesized that x ray fused with magnetic resonance imaging xfm roadmaps might permit direct antegrade crossing and delivery of a ventricular septal defect vsd closure device and thereby reduce procedure time and radiation exposure. Magnetic resonance imaging roadmaps of cardiac structures were obtained from miniature swine with spontaneous vsd and registered with live x ray using external fiducial markers. Case discussion atrial septal defect closure device.

The patches used in asd vsd closures are a synthetic material that is designed to be hypoallergenic or non allergenic. The chest radiograph can be normal with a small vsd. 2 article feature images from this case atrial septal defect medical devices in the thorax 5 public playlist.
