This issue of Interventional Cardiology Clinics will explore Transcatheter mitral valve repair and replacement. 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: Transcatheter Mitral Valve Direct Annuloplasty With the Millipede Device, Transcatheter Mitral Valve Replacement with Intrepid, Transcatheter Mitral Valve Replacement with Tendyne, Treatment of functional mitral regurgitation with transcatheter edge-to-edge repair, Transcatheter Edge-to-Edge repair for Degenerative Mitral Regurgitation, Predicting Left Ventricular Outflow Tract Obstruction Following Transcatheter Mitral Valve Replacement, Prevention and Treatment of Left Ventricular Outflow Tract Obstruction after Transcatheter Mitral Valve Replacement, and Transatrial implantation of transcatheter heart valve for mitral disease, 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.

Interventional cardiologists are able to perform minimally invasive procedures, such as angioplasty and stenting, due to imaging technologies that allow them to see inside the heart and blood vessels without open surgery. Such imaging often requires injection of contrast media, which are generally safe, but for some patients with drug sensitivities or compromised kidney function, contrast-induced nephropathy (CIN) can result. CIN is a major complication that can increase in-hospital mortality. This issue of Interventional Cardiology Clinica addresses the management, treatment, and prevention of renal complications in the catheterization laboratory.

This issue of Interventional Cardiology Clinics, edited by Jorge Gonzalez and Matthew Price, will span a number of essential topics surrounding Imaging in Intervention. Subjects discussed include: Multimodality Imaging for Transcatheter Mitral Valve Replacement; CT Assessment for Transcatheter Aortic Valve Replacement; Imaging Evaluation and Interpretation for Vascular Access for TAVR; Imaging Evaluation for the Detection of Leaflet Thrombosis after TAVR; CT Imaging Guidance for WATCHMAN LAA Closure; Myocardial viability testing to guide coronary revascularization; Intravascular Ultrasound For Guidance and Optimization of Percutaneous Coronary Intervention; CT-FFR to guide coronary angiography and intervention; Multimodality imaging of the tricuspid valve for assessment and guidance of transcatheter repair; and Three-dimensional printing for structural heart intervention planning, among others.

This issue of the Interventional Cardiology Clinics edited by Jason Rogers covers various approaches, techniques, and therapies for Transcatheter Mitral Value Intervention. Topics include, but are not limited to: Echocardiographic Imaging of the Mitral Valve for Transcatheter Interventions, Use of Computed Tomography to Guide Mitral Interventions, Transseptal Puncture for Mitral Interventions, MitraClip Therapy for Mitral Regurgitation: Primary MR, Coronary Sinus-Based Approach to Mitral Regurgitation, and Transcatheter Mitral Valve Replacement.
