Stem cell 'coronary heart patch' strikes nearer to clinic

The promise of stem cells to deal with heart problems might quickly be a step nearer to scientific software as scientists from three establishments search to good and take a look at three-dimensional "coronary heart patches" in a big animal mannequin -- the final large hurdle earlier than trials in human sufferers. In idea, the center patches, engineered tissue composed of the a number of several types of cells that make up coronary heart muscle, could be implanted to interchange diseased or broken tissue and would carry out all of the capabilities of wholesome, beating coronary heart muscle. Utilizing stem cells to deal with heart problems is a grail of regenerative drugs, explains Timothy J. Kamp, a College of Wisconsin-Madison heart specialist and co-director of the UW-Madison Stem Cell and Regenerative Drugs Middle. Treating diseased hearts by implanting wholesome, lab-grown cells to interchange broken tissue has been an aspiration of stem cell biologis...

Credit: Pantheris Removing plaque from clogged arteries is a common procedure that can save and improve lives. This treatment approach was recently made even safer and more effective with a new, high-tech catheter that allows cardiologists to see inside the arteries for the first time, cutting out only the diseased tissue. Interventional cardiologists at Sulpizio Cardiovascular Center at UC San Diego Health are the first in the region to use this technology. The new image-guided device, Avinger's Pantheris™ Lumivascular atherectomy system, allows doctors to see and remove plaque simultaneously during an atherectomy - a minimally invasive procedure that involves cutting plaque away from the artery and clearing it out to restore blood flow. The new technology treats patients suffering from the painful symptoms of peripheral artery disease (PAD), a condition cause...
