ACC.12 Highlights for Surgeons

New research was recently presented at ACC.12, the annual scientific meeting of the American College of Cardiology, from March 24-27 in Chicago. The features below highlight just some of the studies that emerged from the meeting that pertain specifically to the surgeon audience.  >> Positive Outcomes Observed With TAVI >> Assessing the Safety of On- & Off-Pump CABG >> TAVR Comparable to Open-Heart Surgery at 2 Years >> Bariatric Surgery Yields Big Rewards for Obese Diabetics >> Underweight Patients at Increased Risk During ICD Procedures >> Improving the Quality of ACS Care       Positive Outcomes Observed With TAVI The Particulars: Transcatheter aortic valve implantation (TAVI) involves insertion of a bioprosthetic valve into a diseased native aortic valve and represents a potentially less invasive option than surgical replacement. Currently, TAVI has been used mostly in non-operable patients. Data Breakdown: A study was conducted in high-risk patients with severe aortic stenosis who underwent TAVI at 44 centers. Major adverse cardiac and cerebrovascular events at 30-days follow-up occurred in 8.3% of patients receiving TAVI. Total mortality, cardiac mortality, stroke, and life-threatening or disabling bleeding rates were 4.5%, 2.2%, 2.9%, and 4.9%, respectively. Persistent, significant improvements in aortic valve function were also observed. Take Home Pearl: In high operative risk and non-operable patients, TAVI appears to be safe and effective. Assessing the Safety of On- & Off-Pump CABG The Particulars: CABG is one of the most commonly performed cardiac operations, but small randomized trials and meta-analyses have yet to determine conclusively if less-invasive off-pump CABG has better outcomes than on-pump CABG. Data Breakdown: A trial of nearly 5,000 patients with coronary artery disease...
