A 90-year-old patients underwent valve-in-valve transcatheter aortic valve implantation via the transfemoral route in view of the patient’s prohibitively high surgical and anesthetic risk.
Two Occlutech paravalvular leak devices were successfully delivered in a 67-year-old patient with rheumatic heart valve disease using a simultaneous double-transapical access with double-wire technique.
The authors report the development of new ventricular septal defects after TAVR in 4 patients with left ventricular outflow tract calcification; they discuss imaging and post-TAVR management of these patients.   J INVASIVE CARDIOL 2016;28(7):E59-E6…
This study examines the association of clinical, angiographic, and procedural variables with contrast volume administered during 1330 CTO-PCIs performed at 12 experienced United States centers.
A review of paclitaxel-coated balloons as an emerging therapeutic option for the invasive management of infrainguinal peripheral artery disease. 
A review of the CardioMEMS heart failure system that summarizes implantation procedure, discusses the required imaging steps, reviews procedural supplies, and presents a series of case studies to illustrate clinically relevant issues.
With growing acceptance and ease of use, short adenosine infusion may not prove the deterrent it once seemed, and some form of pressure-flow measurement will likely advance to the point of gold standard.
The authors hypothesize that a certain resting non-hyperemic index of coronary and aortic pressures (Pd/Pa) can obviate the measurement of fractional flow reserve and avoid the use of adenosine administration.
Balloon sizing can complement multidetector CT for annular sizing in TAVR, especially in patients with moderate/severe annular calcification, borderline annular size, and non-tubular LVOT.
