Prosthetic valve mismatches common in transcatheter valve replacement, ups risk of death

Health Problems

In the largest multi-institutional study to date, led by researchers from Penn Medicine, the team found that among patients who underwent a transcatheter aortic valve replacement (TAVR), a high number experienced severe and moderate cases of prosthesis-patient mismatch (PPM)—meaning the implanted heart valve is too small for the patient which can lead to inadequate blood flow. The team also found […]

Previous stroke tied to higher risks in aortic valve replacement

Health Problems

(HealthDay)—For patients undergoing surgical aortic valve replacement (SAVR), previous stroke is a risk factor for recurrent ischemic stroke and major adverse cardiovascular events (MACE), according to a study published online April 25 in JAMA Cardiology. Charlotte Andreasen, M.D., from the Copenhagen University Hospital Herlev and Gentofte in Denmark, and colleagues conducted a cohort study involving 14,030 patients with aortic valve […]

New technique makes heart valve replacement safer for some high-risk patients

Health Problems

Scientists have developed a novel technique that prevents coronary artery obstruction during transcatheter aortic valve replacement (TAVR), a rare but often fatal complication. The method, called Bioprosthetic Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA), will increase treatment options for high-risk patients who need heart valve procedures. The findings by researchers at the National Institutes of Health […]
