The burden and impact of sleep deprivation on both patient care and on the health of interventional cardiologists is not well understood. Due to the nature of emergent procedures occurring in the cardiac catheterization laboratory, interventionalists are prone to suffer from acute and/or chronic sleep deprivation. Sleep deprivation has been associated with numerous adverse effects, such as impaired performance, cognitive deficits, reduced psychomotor vigilance, and workplace errors and injuries, among many others. Although sleep deprivation has been linked to more errors in trainees, there is paucity of data addressing outcomes in interventional cardiology. The purpose of this overview is to explore the possible impact of sleep deprivation on interventional cardiology in relation to patient care and physician health, and examine potential approaches to this issue.

Distal coronary perforation can cause early or late tamponade and is usually treated with fat or coil embolization. An alternative treatment strategy is occlusion of the ostium of the perforated vessel via implantation of a covered stent in the main vessel, which is typically achieved using the ping-pong guide catheter technique. In this technique, a balloon is inflated over one guide catheter to stop pericardial bleeding and a covered stent is delivered through a second guide catheter due to inability to fit both a balloon and a covered stent through a single guide catheter. With development of lower profile rapid exchange covered stents, a single guide catheter can be used to both occlude the target vessel and deliver the covered stent. We describe a case of distal vessel perforation in which a balloon was inflated to stop pericardial bleeding, followed by delivery of a covered stent (Graftmaster, Abbott Vascular) through a single 8-Fr guide catheter. This "block and deliver" technique represents a novel paradigm for treating coronary perforations through a single guide catheter, obviating the need for the ping-pong guide catheter technique. © 2017 Wiley Periodicals, Inc.
