The replacement valve often made of cow or pig heart tissue is compressed in the catheter and expands into place after delivery. The American Heart Association provides a full explanation with illustrations. French cardiologist Alain Cribier, MD, is credited with performing the first successful TAVR, in , in France, according to the American College of Cardiology.
The U. Food and Drug Administration FDA first approved the procedure in for certain patients at the highest risk from major surgery. Subsequent studies showed that TAVR was at least as effective and sometimes superior in low-risk patients with severe AVS. The procedure was studied and improved through various trials, most notably the PARTNER Placement of Aortic Transcatheter Valves trials, conducted at numerous academic medical institutions, which prompted the FDA to gradually expand its approved use for all patients with severe cases of the disease.
The treatment is now commonly used in lieu of open-heart surgery. In the early s, clinical trials demonstrated the power of a class of drugs to lower blood sugar in patients with type 2 diabetes. The drugs inhibit the ability of a protein SGLT2 to make the body reabsorb glucose into the kidneys — which, in people with diabetes, drives their glucose levels too high.
Over time, doctors and researchers found that the drugs, called SGLT2 inhibitors, also provided protections against heart failure and the worsening of kidney disease by lowering blood pressure, reducing plasma volume which reduces the workload on the heart , and lowering sympathetic nervous system activity.
Academic medical centers have played key roles in developing, refining, and studying SGLT2 inhibitors. The FDA first approved the first SGLT2 inhibitor canagliflozin to treat type 2 diabetes in , and since has approved three other SGLT2 inhibitors dapagliflozin, empagliflozin, and sotagliflozin to lower the risk of heart failure, heart attacks, and cardiovascular death in patients with diabetes.
In mitral regurgitation, the flaps of the mitral valve, which controls the flow of blood from the left atrium to the left ventricle, do not close properly. This can cause blood to leak back into the heart in the wrong direction.
While many people do not feel symptoms for years, as the condition progresses it often causes escalating health problems, including shortness of breath, swelling of hands and feet, symptoms of shock such as loss of consciousness , atrial fibrillation, and heart failure.
Mitral regurgitation affects an estimated 1. population , with the prevalence rising to about 9. For many years, people with severe cases of mitral regurgitation had to decide whether to risk open-heart surgery to repair or replace the valve, or live with a defect that might kill them.
MitraClip provides a less invasive option. Through the catheter they deliver a small clip — made of cobalt-chromium with a polyester cover — that attaches to the valve to help it close more completely, as explained by Penn Medicine.
The procedure takes hours. Studies, such as one published last year in The New England Journal of Medicine , have shown that the clip reduces mitral regurgitation, the risk of hospitalization, and the risk of death for up to five years after the procedure. The study was conducted by researchers at numerous universities, including the Icahn School of Medicine in New York, the Cleveland Clinic, and the University of Colorado Hospital.
Development of MitraClip began in the late s at Evalve Inc. later purchased by Abbott , with the first implant in a patient occurring in , according to Abbott.
The FDA initially approved the procedure for certain severely ill patients in , and gradually expanded approvals for more patients.
Drugs such as Ozempic and Wegovy, which are widely used to treat diabetes and obesity, have recently been found to reduce heart attack and stroke. The drugs mimic the intestinal hormone GLP-1 that as explained here triggers the release of insulin which lowers glucose levels , keeping blood sugar down, slowing digestion, and increasing how full a person feels after eating.
The FDA approved the GLP-1 agonist Ozempic as a treatment for diabetes in The agency approved Wegovy for weight loss in , and approved Mounjaro for diabetes and Zepbound for weight loss in Studies have shown that patients who took the drugs for diabetes also experienced significant reductions in adverse cardiac events, according to a review published in in Frontiers in Clinical Diabetes in Healthcare.
Research at the University of Texas Southwestern Medical Center has included the effect of GLP-1 agonists on glucose control and weight loss , while research at the University of Vermont Medical Center has included cardiovascular outcomes.
In addition to reducing such cardiovascular risk factors as glucose levels, weight, lipid levels, and hypertension, the drugs also stimulate production of nitric oxide which expands blood vessels and increases blood flow , reduce oxidative stress thus stabilizing antioxidant levels , and help to reduce inflammation.
About 40, U. babies are born with congenital heart defects CHDs each year, making CHDs the leading cause of infant illness and death associated with birth defects, according to the Centers for Disease Control and Prevention CDC.
In decades past, babies born with a severe CHD almost always died in childhood, often before their first birthdays. Those with less severe cases routinely died by early adulthood. But various medical advances have gradually and significantly prolonged their lifespans. According to the CDC:. In the last year for which a full analysis is available , about 1 million children and 1.

Aortic valve stenosis AVS occurs when the opening of the aortic valve through which blood passes from the main pumping chamber, the left ventricle, to the aorta and out to the body is narrowed, reducing blood flow from the heart to the aorta.
