Novel self-expanding intracoronary prosthesis successfully placed in three
patients with coronary artery disease
DOYLESTOWN, Pa., May 29 /PRNewswire/ -- Three patients with established cardiac ischemia recently became the first recipients of the vProtect Luminal Shield, a self-expanding intracoronary prosthesis designed to limit arterial injury that typically occurs when stents are deployed. The Shield also provides robust biocompatible support for the vessel to ensure that the target coronary artery will remain patent after placement.
The patients were treated May 8-9 by Juan F. Granada, MD (Cardiovascular Research Foundation, New York, NY) and Juan A. Delgado, MD (Corbic Institute-MUA) at the Corbic Institute-MUA in Envigado, Colombia. The target lesions ranged from 60% to 80% stenosis before the vProtect Luminal Shields were deployed.
In the first patient, a 75% occlusion in the mid-circumflex coronary artery underwent pre-dilatation at low pressure with a 2.5 x 9 mm balloon and then received a 3.5 x 15 mm luminal shield. After gentle post-dilatation, angiography revealed that blood flow had been restored to the distal portion of the treated vessel.
In the second patient, an 80% occlusion in the middle of the left anterior descending (LAD) branch required pre-dilatation with a 2.5 x 9 mm balloon. Additional lumen gain was achieved by Shield placement and post-dilatation, again achieving restoration of blood flow distal to the treated segment.
The third patient was a challenging case with a 65% occlusion in the
mid-LAD, located in a bend near a side branch ostium. The vProtect Luminal
Shield was chosen for this patient based on its mechanical properties,
including high vascular conformability. Because of its flexibility, the
vProtect Luminal Shield was able to access the tortuous anatomy and cross
the lesion successfully. Restoration of flow was achieved without
angiographic evidence of straightening of t
