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.

This issue of Interventional Cardiology Clinics, guest edited by Dr. Srihari S. Naidu, will discuss Interventional techniques for Heart Failure. Subjects covered in the articles include, but are not limited to: Invasive Hemodynamics of Myocardial Disease: Systolic and Diastolic Dysfunction; Invasive Hemodynamics of Pericardial Disease: Constriction and Tamponade; Invasive Hemodynamics of Pulmonary Disease and the Right Ventricle; TAVR and MitraClip to Reverse Heart Failure; Mechanical Circulatory Support in Acute Decompensated Heart Failure and Shock; Adult Congenital Interventions in Heart Failure; Future Directions in Device Treatment of Heart Failure; and Prioritizing and Combining Interventional Therapies for Heart Failure, among others.

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.

This issue of Interventional Cardiology Clinics will explore Updates in Percutaneous Coronary Intervention. Curated by the series Editor-in-Chief, Dr. Matthew J. Price, this issue will cover topics and advances in the field that are relevant for practicing clinicians. This issue is one of four selected each year by Dr. Price. The volume will include articles on: Current Concepts in Intraprocedural Pharmacology During PCI; Periprocedural Myocardial Infarction in Contemporary Practice; Newer Generation Metallic Stents: Design, Performance Characteristics, and Outcomes; Distal Transradial Access for Coronary Angiography and Intervention; Clinical Outcomes Data for iFR-guided PCI; Culprit-only or Complete Revascularization During STEMI in Patients with and Without Shock; Technical Approaches to Left Main Coronary Intervention: Contemporary Best Practices; Robotic Assisted Percutaneous Coronary Intervention; Orbital Atherectomy: A Comprehensive Review; and Percutaneous revascularization of spontaneous coronary artery dissection, among others.

Among the most recently developed procedures for treating heart disease in a minimally invasive way are the techniques for percutaneous treatment of valvular heart disease. These are important advances because the only alternative is open heart surgery, which is not an option for many high-risk patients. This issue provides a detailed description of several percutaneous procedures, including trans-catheter aortic valve implantation.
