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

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 will publish in the Journal of the American College of Cardiology: Cardiovascular Interventions on April 2.
