Coronary calcification inhibits stent expansion. We sought to establish an intravascular ultrasound–derived calcium score to predict stent underexpansion.

Although stent underexpansion on intravascular ultrasound (IVUS) has been a major predictor for adverse outcomes in previous studies, these studies have primarily focused on angiographic restenosis or repeat revascularization with short-term follow-up. This study sought to evaluate the long-term benefit of different criteria for IVUS-defined optimal stent expansion on hard clinical outcomes.

Compared with angiographic guidance, intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) is associated with better clinical outcomes. However, its very long-term clinical effect is still unclear in patients undergoing PCI for unprotected left main coronary artery disease.

Impact of Diastolic Vessel Restriction on Quality of Life in Symptomatic Myocardial Bridging Patients Treated With Surgical Unroofing: Preoperative Assessments With Intravascular Ultrasound and Coronary Computed Tomography Angiography

Despite optimal medical therapy, a myocardial bridge (MB) can cause life-limiting symptoms in a subset of patients. While surgical unroofing has been shown to improve MB-derived refractory angina, diagnostic indices of clinical symptoms and predictors of improvement following surgery are yet to be elucidated.

Tricuspid edge to edge repair (TEER) is a novel treatment for severe tricuspid regurgitation and is highly dependent on intraprocedural image quality. To date, transesophageal echocardiography (TEE) has been the primary imaging modality used to guide TEER. The role of intracardiac echocardiography (ICE) has not been assessed. The objective of this study was to describe the use and role of 2-dimensional ICE in the early experience of TEER.

Several studies have evaluated preprocedural imaging predictors of left ventricular outflow tract obstruction (LVOTO) after transcatheter mitral valve replacement. The patient cohorts in these studies were heterogeneous and included patients with transcatheter mitral valve replacement in failed bioprostheses, annuloplasty rings, and severe mitral annular calcification (MAC). The goal of this study was to evaluate predictors of LVOTO specific to patients undergoing valve-in-MAC.

Access site vascular and bleeding complications remain problematic for patients undergoing transcatheter aortic valve replacement (TAVR). Ultrasound-guided transfemoral access approach has been suggested as a technique to reduce access site complications, but there is wide variation in adoption in TAVR. We performed a systematic review and meta-analysis to compare access site vascular and bleeding complications according to the Valve Academic Research Consortium-2 classification following the use of either ultrasound- or conventional fluoroscopy-guided transfemoral TAVR access.
