Initial Clinical Experience with the Pantheris SV Catheter

Abstract: A pilot study was conducted of a small diameter atherectomy catheter for use in vessels below the knee. A total of 383 procedures were performed with the catheter in lesions from the superficial femoral artery (SFA) to the peroneal artery, resulting in a 77% decrease in the percent luminal stenosis of targeted vessels. The mean luminal stenosis was reduced from 87% pre-procedure (range 60% to 100%) to 19% (range 5% to 40%) after atherectomy with the Pantheris SV catheter. Following adjunctive therapy, primarily angioplasty, the mean residual stenosis decreased further to 7% (range 0 to 20%). Within this study, a total of 117 single lesions distal to the popliteal artery were treated—56 in the anterior tibial artery (AT), 33 in the posterior tibial artery (PT), 13 in the tibioperoneal trunk (TPT), and 15 in the peroneal artery. In these lesions, atherectomy alone decreased luminal stenosis by 78%. Atherectomy of infrapopliteal lesions by the Pantheris SV catheter shows promising technical and clinical outcomes in this initial pilot study.

OCT an Alternative to Radiation
Using OCT for CTO Crossing and Atherectomy

Abstract :During a typical cath lab procedure, x-ray scanning is performed to guide the physician and technologists. For the patient, this may amount to insignificant radiation exposure. However, the physicians and their staff do not leave the lab after one patient. For them, the process just repeats itself—often, for many years.

With an interest in reducing the risks that interventionists face, new technologies have demonstrated the ability for physicians to improve both patient and operator safety.

The Diagnostic Gap
Limitations of 2D Angiography May Lead to Increased Clinical Risk

Abstract: “Leave nothing behind” is a clinical mantra that many clinicians falsely limit to reduced stent utilization. In reality, this concept emerged during surgical endarterectomies and was in reference to elimination of luminal plaque burden – thus leaving no plaque behind. This foundational principle has been shown to translate to significantly improved laminar flow surfaces and favorable patency at 5 years.
