This issue of Interventional Cardiology Clinics reviews percutaneous circulatory support device use in several situations, including left and right ventricular shock, cardiopulmonary resuscitation, and infarct size reduction. Keep up to date with the latest developments in this rapidly evolving field.

This issue of Interventional Cardiology Clinics, Guest Edited by Dr. Brian O'Neill, will focus on Mechanical Circulatory Support. This issue is one of four selected each year by the series Consulting Editor, Dr. Marvin H. Eng. Mechanical circulatory support (MCS) plays an important role in the management of a variety of patients with a range of conditions in interventional cardiology. As many times the question of MCS arises in the most critical of patients, an understanding of each of the devices along with which patients may potentially benefit is vital. This issue aims to provide a review of the various options of MCS, as well as a variety of scenarios in which MCS may play a beneficial role in the management of patients.

In ST segment elevation myocardial infarction (STEMI), the coronary artery is completely blocked by a blood clot. It is the most serious type of heart attack. The best treatment for STEMI patients is to have the blocked artery opened by balloon inflation within 90 minutes of arriving at a hospital. The 90-minute window is called "door-to-balloon time. The shorter the door-to-balloon time, the greater the chance of survival. Treatment of this life-threatening illness is reviewed in this issue.
