The Role of CT-Guided Optimal Fluoroscopic Viewing Angle for Coronary Engagement After TAVR.

We report the case of an 89-year-old woman with prior transcatheter aortic valve replacement who underwent successful left coronary artery engagement and left circumflex percutaneous coronary intervention using patient-specific computed tomography fluoroscopic projections. ().

Aortic Annulus S-Curve: Implications for Transcatheter Aortic Valve Replacement and Related Procedures, Part 1.

Most transcatheter aortic valve replacement-related procedures (eg, transcatheter aortic valve replacement implantation depth, commissural alignment, coronary access, bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction, paravalvular leak closure) require an optimal fluoroscopic viewing angle located somewhere along the aortic annulus S-curve. Chamber views, coronary cusp and coronary anatomy, can be understood along the aortic annulus S-curve. A better understanding of the optimal fluoroscopic viewing angles along the S-curve may translate into increased operator confidence and improved safety and efficacy while reducing procedural time, radiation dose, contrast volume, and complication rates.

Pericarditis Secondary to an Acupuncture Needle Extracted Via a Transjugular Approach.

Acupuncture is generally considered safe; however, cardiac complications can occur. We describe a case of refractory pericarditis requiring transvenous extraction of an acupuncture needle from within the right ventricular cavity. ().
