In a prospective observational study, 40 patients were treated with coronary stent grafts covered by a polytetrafluoroethylene membrane. These devices may be regarded as therapy of choice for acute coronary rupture; treatment of conventional in-stent restenosis was not associated with a favorable outcome, whereas the promising results in degenerated vein grafts warrant a randomized, controlled trial.

Myocardial bridging is a frequent anomaly of the heart in humans and other animals. A myocardial bridge is typically characterized by the systolic narrowing seen with traditional catheter angiography, but this abnormality is not by itself a sign of ischemia or the need for intervention. In particular, transient spontaneous angina must be corroborated by reproducible narrowing during acetylcholine testing; this narrowing occurs during resting conditions and is responsive to nitroglycerin administration.

Pickering syndrome, characterized by recurrent episodes of flash pulmonary edema (FPE) and renal impairment, is associated with renal artery stenosis (RAS). This case highlights its manifestation and management in an older adult patient. An 86-year-old woman with hypertension, chronic kidney disease, and a single functioning kidney presented with recurrent FPE episodes.

Coronary computed tomography angiography (CTA) analysis can help in the planning of percutaneous coronary intervention (PCI). Fractional flow reserve derived from coronary CTA (FFR), coronary CTA-derived regional myocardial mass, and FFR virtual PCI planner can facilitate decisions concerning sheath and guide catheter selection, stent lengths on the basis of predicted post-PCI FFR, optimal fluoroscopic angles, evaluation of provisional vs 2-stent bifurcation PCI techniques, and assessment of the magnitude of jeopardized myocardial mass in cases with side branch compromise. This case series illustrates the emerging opportunities for coronary CTA-based planning of bifurcation PCI.

A 77-year-old man with a history of a Bentall procedure presented with acute decompensated heart failure. Investigations revealed severe bioprosthetic aortic valve regurgitation and a large pseudoaneurysm eroding the sternum. We describe the multimodal imaging and heart team planning to stent the pseudoaneurysm with an endograft followed by transcatheter valve-in-valve implantation.

A 73-year-old man presented with acute coronary syndrome secondary to stent failure. Intravascular imaging identified a recurrent protruding calcific nodule as the mechanism, which was effectively treated with low-speed rotablation, resulting in ablation of the nodule allowing the application of a drug-coated balloon.
