Background: Primary cardiac sarcoidosis (CS) is rare, and concomitant involvement of the coronary arteries is rarer still. Successful diagnosis of this disease is difficult due to its nonspecific symptoms which mimic those of idiopathic dilated cardiomyopathy (IDCM).
Methods And Results: We describe a 47-year-old Caucasian male who underwent orthotopic heart transplant for presumed IDCM. Examination of the explanted heart revealed numerous nonnecrotizing granulomata throughout, similar granulomata in the walls of the large coronary arteries, and large areas of fibrosis.
Conclusions: In cases of IDCM with symptoms of angina or acute coronary syndrome, the possibility of CS should be considered. Herein, we present this case and a review of the relevant literature.

Background: Evidence regarding drug-coated balloon (DCB)-only angioplasty in de novo lesions of large vessels is still limited and mainly focused on paclitaxel-coated balloon. We aimed to analyze the safety and efficacy of sirolimus-coated balloon (SCB)-only angioplasty in de novo lesions in large vessels compared to drug-eluting stent (DES).
Methods: In this retrospective, dual-center, case-control study, we enrolled all consecutive patients treated between January 2022 and January 2024 with SCB-only angioplasty in de novo lesion in large vessel (> 2.

Heart disease is a category of various conditions that affect the heart, which includes multiple diseases that influence its structure and operation. Such conditions may consist of coronary artery disease, which is characterized by the narrowing or clotting of the arteries that supply blood to the heart muscle, with the resulting threat of heart attacks. Heart rhythm disorders (arrhythmias), heart valve problems, congenital heart defects present at birth, and heart muscle disorders (cardiomyopathies) are other types of heart disease.

Replicating the contractile function of arterial tissues in vitro requires precise control of cell alignment within 3D structures, a challenge that existing bioprinting techniques struggle to meet. In this study, we introduce the voxel-based embedded construction for tailored orientational replication (VECTOR) method, a voxel-based approach that controls cellular orientation and collective behavior within bioprinted filaments. By fine-tuning voxel vector magnitude and using an omnidirectional printing trajectory, we achieve structural mimicry at both the macroscale and the cellular alignment level.

Renal denervation is an emerging strategy for the management of uncontrolled hypertension. However, real-world experience is still modest, in particular for the management of complex anatomy, with available data being limited to the selected population of randomized clinical trials. We first describe the feasibility of delivering the renal denervation system to the target site with a child-in-mother technique, using a common coronary guiding extension, in a patient with severe tortuosity and double renal arteries.

Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.
