Transcatheter closure of the atrial septal defect (ASD) resulted in significant reductions in tricuspid regurgitation (TR) and improvements in right ventricular dimensions, according to a new study in JACC: Cardiovascular Interventions.

Scientists have discovered a protein that appears to mimic the benefits of weight-loss surgery without requiring an operation.

Low-dose colchicine therapy can favorably remodel coronary plaque following acute coronary syndrome (ACS), reducing one of the major predictors of future cardiovascular events, according to a new study in JACC: Cardiovascular Imaging.

Cardiovascular research has traditionally focused on hard clinical endpoints such as markers of disease progression, adverse events and death. But now researchers are calling for more studies that incorporate the viewpoints of patients and caregivers, both in trial design and execution and in measuring outcomes like quality of life, time off work, out-of-pocket expense and caregiver burden.


Clinical guidelines don’t recommend valve replacement for patients with severe aortic stenosis (AS) demonstrating normal flow and low gradients. But maybe they should, according to new research published in JACC: Cardiovascular Imaging.

 - Money Sand

Medical device company Medtronic was already projecting a $250 million financial hit due to Hurricane Maria before wildfires in northern California forced it to shut down four facilities in Santa Rosa on Oct. 9. A Medtronic spokesperson said the approximately 840 employees who live in the area have all reported being safe, and the company plans to reopen three of the four plants next week.

Google Maps has pulled a calorie-counting feature from its iPhone application after a wave of complaints that it was dangerous or insulting.

 - Mitral Valve Repair

About two-thirds of mitral regurgitation cases are classified as degenerative, implying little can be done to prevent them as people age. But a new study in PLOS Medicine suggests high blood pressure could be a modifiable risk factor for the common heart valve disorder.

A one-month education and screening program at a rural tertiary medical center reduced inappropriate cardiac catheterization referrals by primary care physicians (PCPs) from 17 percent to zero percent.

Despite encountering more short-term complications after transcatheter aortic valve replacement (TAVR), women have better long-term survival rates than men, according to a meta-analysis of 47,188 patients. However, they remain at greater risk for stroke.
