In angioplasty procedures, a balloon is fed through a catheter and used to prop open an artery that has become narrowed or blocked. In cases where stenting is appropriate, a stent mounted on a balloon is inserted and inflation of the balloon expands the stent against the blocked artery wall to hold the vessel open. The balloon is then deflated and the catheter is withdrawn. Stent treatment of arteries holds them open and improves blood flow to the heart. In cases where post-dilatation is needed, a high-pressure balloon is inflated inside a stent to help better place the stent against the vessel wall.
Vijaya B. Kolachalama, PhD, assistant professor of medicine at Boston University School of Medicine, has received a Scientist Development grant from the American Heart Association.
A new gene therapy that targets the heart and requires only one treatment session has been found safe for patients with coronary artery disease, according to a successful trial carried out in Finland.
As open surgery has gradually been replaced by minimally-invasive and image-guided procedures, tissue adhesives are taking the place of sutures and surgical staples.
Michael Koumjian, a heart surgeon for nearly three decades, said he considered treating the sickest patients a badge of honor. The San Diego doctor was frequently called upon to operate on those who had multiple illnesses or who'd undergone CPR before arriving at the hospital.
Patients with obesity have a higher risk of infection within 30 days after receiving heart bypass surgery, according to a series of studies conducted by University of Alberta researchers at the Faculty of Rehabilitation Medicine.
EuroPCR 2017, the official annual meeting of the European Association for Percutaneous Cardiovascular Interventions, pushed back barriers in bringing together young and established interventional cardiologists to learn from past successes, build understanding and experience of new percutaneous interventional approaches, and develop innovations for the future at this year's course held from 16 to 19 May 2017 at the Palais des Congrès in Paris, France.
Royal Philips will showcase its market-leading image guided therapy solutions at EuroPCR 2017 (Paris, May 16 – 19, 2017) to advance interventional cardiology and make care more personalized, while optimizing patient care and hospital budgets. This year, the healthcare industry is celebrating the 40th anniversary of angioplasty, the minimally invasive treatment of obstructed blood vessels, and as a leader in interventional cardiology, Philips is reinforcing its longstanding commitment to transforming cardiac care with meaningful innovations.
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have discovered a new mechanism of action of metoprolol, a drug that can reduce the damage produced during a heart attack if administered early.
While heart disease remains the leading cause of death for both men and women in the U.S., according to the Centers for Disease Control, advances in medicine over the past 40 years have led to a substantial reduction in cardiovascular-related deaths.
Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein, often in the deep veins of the legs, thigh or pelvis. Those clots can break loose, travel to the lungs and block blood flow, causing a pulmonary embolism.
A new tool for assessing the narrowing of the heart's arteries was found to be as effective as current methods and less painful for patients.
Physician researchers at Thomas Jefferson University suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents.
Patients experiencing a major heart attack often have more than one clogged artery, but under current guidelines doctors typically only clear the blockage responsible for the heart attack.
For patients experiencing angina (chest pain) or a heart attack, a new tool called instantaneous wave-free ratio (iFR) was equivalent to the currently-preferred tool, fractional flow reserve (FFR), in terms of incidence of major adverse events according to two studies presented at the American College of Cardiology's 66th Annual Scientific Session. The studies also showed iFR resulted in markedly less patient discomfort and reduced procedure-related adverse events compared to FFR.
Common impotence drugs such as Viagra may have a life-prolonging effect on patients who have suffered a myocardial infarction, a paper published by researchers at Karolinska Institutet suggests.
Hospitals can improve patient care and reduce costs associated with coronary angioplasty if cardiologists perform more of these procedures through an artery in the wrist and if they take steps to discharge such patients on the same day, according to a new study led by Washington University School of Medicine in St. Louis.
If hospitals can perform more transradial, same-day percutaneous coronary intervention, or PCIs, not only will patients benefit because it is associated with have less complications, but collectively, hospitals across the U.S. could save $300 million each year, according to research published today in JACC: Cardiovascular Interventions.
Over 93 percent of heart attack patients are receiving stents within the guideline-recommended threshold of 90 minutes after arriving at the hospital, with the median time to stenting only 59 minutes, according to a broad report on trends in heart disease care from the American College of Cardiology's National Cardiovascular Data Registry published in the Journal of the American College of Cardiology.
A physician at Scripps Health's Prebys Cardiovascular Institute has become the first in the Western United States to treat heart attack patients with a new supersaturated oxygen (SSO2) system in an attempt to reduce permanent damage to their heart muscle.
The inability of cells to eliminate damaged proteins and organelles following the blockage of a coronary artery and its subsequent re-opening with angioplasty or medications - a sequence known as ischemia/reperfusion - often results in irreparable damage to the heart muscle.
