VentureMed launches Flex scoring catheter study

Vascular focused device developer VentureMed said yesterday that it launched a new study of its Flex dynamic scoring catheter, exploring whether the device reduces dissections and the need for bailout stents in peripheral arteries. In the newly launched iDissection Classification study, investigators will use intravascular ultrasound to identify the health of vessels after treatment with the Flex system, the Toledo, Ohio-based company said. The trial is being led by Dr. Nicolas Shammas of Davenport, Iowa’s Midwest Cardiovascular Research Foundation, who led the previous iDissection study. In the previous study, researchers found that after atherectomy, significant dissections in the peripheral arteries were more visible at a ratio of 6 to 1 when using IVUS as compared to standard angiograms. “After the indicative results of the initial iDissection study, I am motivated to look for vessel prep devices that further reduce the need for provisional stenting. I am optimistic about the ability of the Flex Catheter to reduce the rate of high-grade dissections and looking forward to the evaluation,” principal investigator Dr. Shammas said in a prepared statement. VentureMed said that analyzing the presence and severity of dissection after atherectomy “may have been underestimated,” specifically for deeper dissections which the company said are associated with recurrent restenosis, recoil and possible acute closure. The study will evaluate the d...

ConclusionsDrug-coated balloon angioplasty resulted in superior survival of dysfunctional peripheral vascular access at 6 and 12  months, but this result was not statistically significant. Both arms show equivalent complications and similar mortality.Level of EvidenceLevel Ia, therapeutic study, RCT. EBM ratings will be based on a scale of 1-5.

A 38 year-old obese man who is currently smoking was referred to our hospital with chest pain. His electrocardiography and echocardiography suggested myocardial infarction in proximal region of left coronary artery. Emergent coronary angiography revealed 99% stenosis at mid portion of LAD and diffu...

ConclusionsFor patients with uncontrolled hypertension despite receiving medications, renal Doppler ultrasound should be included in the diagnostic workup for secondary hypertension. Once renal artery stenosis is suspected, renal angiography is highly recommended because the technique is able to accurately diagnose stenosis in the branch arteries, unlike computed tomographic angiography and magnetic resonance angiography. Percutaneous transluminal renal angioplasty is the treatment of choice for renal artery stenosis in patients with renovascular hypertension or renal dysfunction.

We report a case of isolated septal myocardial infarction, in which the diagnosis was confirmed not by electrocardiographic, echocardiographic, or angiographic findings, but by nuclear imaging. A 46-year-old man with chest discomfort exhibited ST-segment elevations in leads V1 and V2, and borderline abnormalities of the septal wall motion on echocardiography. Emergency coronary angiography demonstrated delayed flow in the second septal branch of the left anterior descending coronary artery. Intravascular ultrasound showed plaque in the proximal portion of the septal branch without evidence of plaque rupture. No balloon ang...

Semin intervent Radiol 2019; 36: 084-090 DOI: 10.1055/s-0039-1688420Hepatic artery stenosis (HAS) is an infrequent complication of liver transplant; if left untreated, it can lead to hepatic artery thrombosis with high risk of biliary necrosis and graft loss. HAS is diagnosed with screening Doppler ultrasound, together with computed tomography angiography and magnetic resonance angiography. Endovascular treatment with angioplasty ± stent placement is safe and effective with infrequent major complications; however, when complications occur, they can devastate long-term graft survival. Herein, we present...

Authors: Shammas NW, Shammas WJ, Jones-Miller S, Radaideh Q, Shammas GA Abstract BACKGROUND: Luminal gain post balloon angioplasty (PTA) is in part due to the occurrence of dissections. The depth and extent of dissections, however, can influence the short- and long-term outcomes of a procedure. Focal force and scoring balloons have been used to reduce angiographic dissections post PTA. The role of the Flex Vessel Prep (VP) system (VentureMed Group), a dynamic, microincision, non-balloon based system, prior to PTA in reducing and/or limiting severe dissections has not been fully characterized. METHODS: In this p...

We report a 32-year-old female worker presenting pain in her left upper-extremity for 7 months. Her left hand became paler and cold when the temperature decreased, and the symptoms could not be eased through rest, physiotherapy and drugs medication. Diagnoses: Compression of left subclavian artery with axillary and brachial arteries thrombosis was confirmed by duplex ultrasound and computed tomography angiography. ATOS caused by cervical ribs was confirmed by medical history, physical examination, and imaging. Interventions: The patients underwent acute thrombolysis and balloon angioplasty. Outcomes: Symptoms of p...
