Fringe Field Navigation transforms endovascular surgery

A new technique could enable vascular surgeons to reach even the more difficult body regions. Instead of pushing catheters into minute veins, the system, devised in Canada by Professor Sylvain Martel and team at the Polytechnique Montréal Nanorobotics Laboratory, uses magnetic forces to pull a guidewire, or catheter, into remote physical locations, guiding medical instruments into narrow and…

Robot uses AI and imaging to draw blood

Engineers at Rutgers University have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their most recent research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on…

Benefit and risk: drug-coated balloon angioplasty

Scientists of Jena University Hospital, Germany, conducted a meta-analysis to evaluate benefit and risk of paclitaxel-coated balloon angioplasty compared to conventional balloon angioplasty as therapy of intermittent claudication. The study confirms an increased all-cause mortality, which has formerly been stated, and found a broad heterogeneity in the effectivity of the procedure depending on…

“Back to basics” atrial fibrillation procedure could cut waiting lists

A day case catheter ablation procedure which includes only the bare essentials and delivers the same outcomes could slash waiting lists for atrial fibrillation patients, according to late-breaking results from the AVATAR-AF trial presented today at EHRA 2019, a European Society of Cardiology (ESC) congress. With the simplified protocol, 30% more patients could receive catheter ablation for the…

Radial artery catheter failure

2.5 million radial arterial catheters (RAC) are used annually in Europe (USA: 8 million), commonly to monitor arterial blood pressure and take blood samples in surgical, A&E and ICU units. They can fail. For a study of mechanisms that might lie behind premature RAC failure and complications related to RAC in clinical use*, at team at the Radiology/Ultrasound and Anaesthesiology Department,…

Restrictive ruling on cardiac procedure

In the future, TAVIs can only be carried out in German hospitals with cardiac surgery departments and cardiac wards, as decided by the German Government’s Expert Panel on Health (G-BA) last January. An interim arrangement in force until 2016 is anticipated for Heart Centres that currently carry out the TAVI procedure without cardiac surgery departments on site. The Federal Ministry of Health is…

The fall and rise of cardiac surgery innovations

Grandly announced, the da Vinci became the must-have of any self-respecting cardiac surgeon, only to sink into obscurity as quickly as it had risen to stardom. Once the wunderkind of robotic surgery, today this surgical system is merely collecting dust on many a hospital cupboard. A whole slew of methods and technologies were launched with varied fanfares over the past ten years. European…
