Coronary subclavian steal syndrome
Coronary subclavian steal syndrome is the diversion of blood from the coronary circulation to the exercising left upper limb after a coronary artery bypass graft (CABG) using left internal mammary artery [1]. This occurs when there is a high grade stenosis or occlusion of left subclavian artery proximal to the origin of the left internal mammary artery (LIMA). Though it is a rare phenomenon, it is a serious threat to the success of CABG.
Cardiovascular manifestation of coronary subclavian steal syndrome could be angina, myocardial infarction, malignant arrhythmias or heart failure [1]. Cerebral symptoms can occur due to ...

Interview with Medtronic ’s Mark Pacyna on Approval of IN.PACT AV DCB for Failing AV Fistulae
End-stage renal disease (ESRD) patients experiencing kidney failure typically require hemodialysis in order to artificially remove fluid and waste from blood and maintain appropriate electrolyte concentrations. For many patients on hemodialysis, an arteriovenous (AV) fistula is created to link an artery to a vein. Veins are too fragile for frequent access, but arteries are too deep. Creating an AV fistula makes the vein that is linked to an artery more resilient and capable of providing regular vascular access for dialysis.
While effective, and a standard of care for ESRD patients, vessel restenosis can occur over time ...

IN.PACT AV Drug Coated Balloon for Dialysis Patients to Heal AV Fistulaes
Medtronic has won FDA approval to introduce its IN.PACT AV drug-coated balloon as a treatment option for failing arteriovenous (AV) fistulae.
People with non-functional kidneys who undergo dialysis receive AV fistulae, which link an artery to a vein. Veins tend to be too fragile for regular access, but arteries are too deep. Creating an AV fistula makes the connected vein much more resilient and capable of providing vascular access for dialysis.
Eventually, AV fistulae tend to fail because of restenosis, limiting blood flow, and have to be expanded. This is a frequent procedure that comes with dangers, costs, and dis...

Simmons catheter (Sim catheter)
Simmons catheter (Sim catheter)
Simmons catheters (Sim catheters) have been used for cerebral angiography [1] as well as renal angiography [2]. They have 3 different varieties (Sim 1, 2 and 3). 4 French and 5 French sizes are available. Sim catheters can be used for transradial as well as transfemoral approaches. Possibility of engaging the left subclavian by the transradial route has made this an option for angiography of the left internal mammary artery (LIMA) when coronary artery bypass is the option after a diagnostic coronary angiography. Sim catheters comes in handy when there is difficulty in engaging the left subc...

Paladin Carotid PTA Balloon with Embolic Protection Filter Cleared by FDA
Contego Medical, out of Raleigh, North Carolina, won FDA clearance for its Paladin carotid PTA (Percutaneous Transluminal Angioplasty) balloon catheter. The device, used to open up narrow arteries and to post-dilation of self-expanding stents, has a built-in embolic protection filter that traps any debris that may become dislodged and forced to flow downstream of the treatment site.
The filter has pores only 40 micron in width, allowing it to grab onto pretty small pieces of plaque while letting whole blood flow through. The filter is connected directly to the balloon and the two are delivered and deployed at the same time...

Same day discharge for peripheral arterial procedures in elderly – study in CCI
(Peripheral angioplasty – representative image)
Same day discharge after peripheral arterial procedures have been documented to be safe in younger individuals. Now a new study published early online in Catheter and Cardiovascular Interventions [1] has shown that it can be applied in elderly individuals above 70 years as well. The obvious advantage in elderly individuals is that it avoids the risk of delirium, which is common in elderly and demented individuals after night stay in intensive care units.
The peripheral arterial procedures performed where balloon angioplasty, atherectomy and stenting. The study collec...

Contego Medical ’s Vanguard IEP Cleared in Europe for Safer Balloon Angioplasties
Contego Medical of Raleigh, North Carolina won the European CE Mark to introduce its Vanguard IEP peripheral balloon angioplasty system. The product features the firm’s Integrated Embolic Protection (IEP) technology that captures embolic debris coming off occlusions being treated within the superficial femoral artery.
The IEP looks a bit like a parachute that extends around the distal tip of the Vanguard, covering the arterial lumen, whatever its size, so that just about all the blood flows through its filtrating material. Large objects, greater than the 150-micron pores of the parachute, are captured during ball...

First Drug-Coated Balloon Approved By FDA For Leg Blockages
The FDA today announced that it had approved for use in the US the first drug-coated angioplasty balloon catheter to re-open blocked arteries in the thigh and knee (superficial femoral and popliteal arteries). The Lutonix 035 Drug Coated Balloon Percutaneous Transluminal Angioplasty Catheter (Lutonix DCB) is manufactured by CR Bard and has been available in Europe since 2012. … Click here to read the full post on Forbes.

GORE’s VIABAHN Endoprosthesis Gains FDA Approval for Revision of Arteriovenous Access
W.L. Gore (Flagstaff, AZ) has received expanded indication from the FDA for the VIABAHN Endoprosthesis to be used for the treatment of stenosis or thrombotic occlusion at the venous anastomosis of synthetic arteriovenous access grafts. The VIABAHN Endoprosthesis has long been approved for iliac and superficial femoral artery use, but now with the latest approval physicians can use this flexible, low profile endoprosthesis in challenging venous anastomotic locations such as across the elbow and regions where flex angles are greater than 90 degrees.
The VIABAHN Endoprosthesis consists of a nitinol stent structure that s...
