Rotational Atherectomy to Treat in-Stent Recurrent Protruding Calcified Nodule.

JACC Case Rep

January 2025

Cardiovascular Division, St Thomas' Hospital, Guy's and St Thomas' NHS Foundation Trust, London, United Kingdom.

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.

We describe the case of a 52-year-old man with radiation-induced severe mixed aortic and mitral valve disease, thickening of the aortomitral continuity, mitral annular calcification, and porcelain aorta with limited transcatheter treatment options. By replacing the aorta during circulatory arrest, we demonstrate that it is possible to clamp the ascending aorta to facilitate prosthetic aortic and mitral valve replacement.

We present a first in human experience of transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification who was at high risk of left ventricular outflow tract obstruction.

Background: Intravascular imaging (IVI) complements coronary angiography and may help prevent coronary artery perforation (CAP) during percutaneous coronary intervention (PCI).

Objectives: The authors evaluated whether IVI-guided PCI is associated with a lower risk of PCI-related CAP in a real-world cohort.

Methods: This observational study analyzed consecutive PCI procedures from January 2006 to October 2023.

Background: Coronary artery calcium, a marker of coronary atherosclerosis, is often identified on noncoronary chest computed tomography (CT). We wanted to evaluate the correlation between the presence of coronary plaques in coronary artery catheterization and coronary calcifications as shown in noncardiac chest CT.

Methods: A retrospective case-control study consisting of cases (N = 63) and controls (N = 29), aged 18-70 years old, residing in northern Israel and treated in the Intensive Cardiac Care Unit of Ziv Medical Center, between January 2020 and November 2022.
