Coron Artery Dis
January 2025
Intensive Cardiac Care Department, Ziv Medical Center.
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.
Coron Artery Dis

Department of Medicine, Lundquist Institute at Harbor-UCLA Medical Center, Los Angeles.
Background: Coronary artery dominance is determined by the coronary artery emitting the posterior descending artery. In the left dominant system, a greater proportion of coronary flow enters the left coronary artery, potentially influencing calcified plaque development in the left anterior descending artery (LAD).
Methods: This retrospective single-center cohort study analyzed patients who underwent computed tomography angiography from September 2006 to December 2022 at Harbor-UCLA in Los Angeles, California.

Background: Self-expanding valves used in transcatheter aortic valve implantation (TAVI) are designed to allow recapture and repositioning, facilitating optimal placement and mitigating conduction disturbances and paravalvular leakage. Here, we present a rare case in which the Navitor (Abbott Structural Heart, Santa Clara, CA, USA) could not be recaptured.
Case Summary: An 81-year-old Japanese woman with very severe aortic stenosis and a massively calcified nodule at the non-coronary cusp (NCC) underwent TAVI with a 25 mm Navitor valve.
Catheter Cardiovasc Interv
January 2025
Department of Cardiology, Ageo Central General Hospital, Saitama, Japan.
Background: Intravascular lithotripsy (IVL), that generates shockwaves through spark gap discharge between emitters, has been increasingly used to treat severely calcified coronary artery lesions. However, there is a question as to whether IVL has no electrical effects on endocardial tissues or cardiac implantable devices (CIEDs).
Aims: The aim of this study was to investigate the effects of IVL-induced intracardiac potentials on cardiac electrophysiology and CIEDs.
Catheter Cardiovasc Interv

Department of Cardiology, Heart Center and Beijing Key Laboratory of Hypertension, Beijing Chaoyang Hospital, Capital Medical University, Beijing, China.
We report the case of a 73-year-old male with a history of recurrent coronary interventions who presented with progressive angina and was diagnosed with a chronic total occlusion (CTO) of a heavily calcified and tortuous right coronary artery (RCA). Standard antegrade and retrograde techniques were attempted but failed due to the complexity of the lesion. A novel "Drag-Drill" technique was employed, utilizing a retrogradely externalized RG3 guidewire as a rotational atherectomy wire, enabling successful rotational atherectomy and percutaneous coronary intervention (PCI).
