Significant narrowing of the left main coronary artery is a high-risk condition with significant mortality risk. Bypass surgery is the current gold-standard treatment for unprotected left main (ULM) disease. Stenting utilizing drug-eluting stents (DES) is another therapeutic option for patients with ULM disease considered too high risk for bypass surgery or for patients who simply refuse bypass surgery. We have had great initial success with ULM stenting using DES in 10 selected patients at Baylor University Medical Center. Ongoing multicenter, international randomized studies comparing percutaneous coronary intervention with DES and bypass surgery will shed more light on the best treatment strategy for ULM coronary disease.

The AmBulatory Closure Device Percutaneous Intervention (ABCD-PCI) study is a multicenter randomized prospective controlled trial evaluating the safety of and patient satisfaction with same-day discharge following ambulatory percutaneous intervention with a closure device. This article reviews the findings from a single center, Baylor Jack and Jane Hamilton Heart and Vascular Hospital, from October 2008 through April 2010, with 23 patients in the same-day discharge group and 21 patients in the next-day discharge group. There were no differences between the groups in demographic or procedure characteristics. Outcomes were measured by a questionnaire and 7-day and 30-day follow-up phone calls. Results showed that same-day discharge after percutaneous intervention with a closure device is as safe as next-day discharge. However, there was a trend for a higher comfort level among patients in the next-day discharge group.
