Structural Heart

 - structural heart, Medtronic CoreValve

Transcatheter aortic valve replacement (TAVR) continued to hold its own against surgery in low-risk patients with severe aortic stenosis, based on two-year results presented May 19 at EuroPCR in Paris.

 - Melody Transcatheter Pulmonary Valve

After a median follow-up period of 4.5 years, most patients who underwent transcatheter pulmonary valve replacement with the Melody valve had positive hemodynamic and clinical results, according to a prospective study.

 - Elderly Patient

By using an online tool to track central venous catheters (CVCs), physicians reduced the use of CVCs by 46 percent at two internal medicine teaching clinics.


Five years after patients underwent transcatheter aortic valve replacement (TAVR), 45.5 percent were still alive, according to an analysis of a United Kingdom registry.

 - Mitral Valve Repair

For patients undergoing mitral valve (MV) repair, concomitant tricuspid annuloplasty was safe and effective and minimized the risk of tricuspid regurgitation, according to a retrospective analysis.

ACC.15: TAVR safe and effective in low-risk patients, with caveats

When comparing transcatheter and surgical aortic valve replacements, findings presented at the American College of Cardiology scientific sessions noted that there were no differences in death, stroke, or MI at one year. However, there were some differences in outcomes, leaving neither on top.

ACC.15: PARTNER I outcomes equal for TAVR, surgery at 5 years

High-risk patients with severe aortic stenosis had similar outcomes at five years in both arms of the PARTNER I trial, a finding that the presenter at the American College of Cardiology scientific session called a win for the intervention.

ACC.15: CoreValve’s advantage over surgery widens at 2 years

So it wasn’t a fluke. Two-year results from the CoreValve pivotal trial for high-risk patients with severe aortic stenosis reaffirmed that the transcatheter aortic valve replacement device is superior to standard surgery. The results were presented March 15 at the American College of Cardiology scientific session.
