Background: Cardiac resynchronization therapy (CRT) has become a successful treatment option for symptomatic heart failure in patients with poor left ventricular (LV) systolic function and broad QRS complex in the surface electrocardiogram (ECG).
Case Report: In this report we present a case of a 70-year-old woman with advanced heart failure due to ischaemic heart disease who underwent an upgrade from VVIR stimulator (pacemaker, PM) to cardiac resynchronization therapy defibrillator (CRT-D). The first attempt was unsuccessful due to problems with inefficient cannulation of the orifice of the coronary sinus (CS). After performing a 3D reconstruction with a 128-slice CT scanner, it was possible to carry out the up-grade to CRT-D resulting in enormous clinical improvement.
Conclusions: The case represents an example of the usefulness of 3D reconstruction with the 128-slice CT scanner used after failed CRT-D implantation due to difficulties with efficient cannulation of the coronary sinus orifice in a rare anatomical variant.

Objectives: The study aimed to evaluate the relationship between maxillary sinus volume and various sinonasal anatomical variants, as detected by multi-detector computed tomography, and their associations with chronic rhinosinusitis (CRS).
Material And Methods: A case-control study was conducted with 103 patients presenting with chronic sinonasal symptoms (cases) and 50 asymptomatic individuals (controls). A 128-slice computed tomography scanner was used to measure maxillary sinus volume and assess anatomical variants, such as a deviated nasal septum (DNS), concha bullosa (CB), and agger nasi cells.

Background And Objectives: Colorectal lesions can present as a mass or as focal or diffuse thickening of the colon wall and may also be associated with abnormalities in the perienteric region. Multidetector computed tomography (MDCT) enables simultaneous imaging of both extracolonic structures and the gut wall. It is instrumental in assessing tumor extent, detecting pericolic dissemination, including lymph node involvement, and identifying metastases.

Article Synopsis
- The study aimed to assess trabecular attenuation of the L1 vertebral body using low-dose CT in adult patients with multiple myeloma (MM), smoldering myeloma (SMM), and monoclonal gammopathy of undetermined significance (MGUS).
- The study included 73 patients, with evaluations of trabecular bone density based on CT scans, showing significant differences in bone density among the different patient groups.
- Results indicated that lower Hounsfield unit (HU) values are associated with poorer progression-free survival, highlighting the potential clinical relevance of L1 attenuation values in managing these conditions.

Introduction Obesity, a prevalent global health concern, is associated with various chronic conditions, including cardiovascular diseases and metabolic syndrome. Visceral adiposity, the accumulation of fat around internal organs, has a more significant impact on metabolic health compared to subcutaneous fat. Accurate assessment of visceral fat is critical for predicting metabolic risks.

Introduction The pericardial fat pad, located anteriorly to the heart between the pericardium and myocardium, has garnered significant interest in cardiovascular research due to its potential role in the pathophysiology of various cardiac conditions. Despite its proximity to the myocardium, it is distinct from the epicardial fat depot found between the myocardium and the visceral layer of the pericardium. Studies have shown that excess pericardial fat is associated with an increased risk of heart failure and other cardiovascular diseases.
