Background: The Ejection Fraction (EF) represents a fundamental pillar for the phenotypic classification and clinical management of cardiovascular diseases. Although trans-thoracic echocardiography (TTE) acts as the first-line examination and cardiac magnetic resonance (CMR) is the reference gold standard, cardiac computed tomography (CCT) has undergone a technological evolution. The advent of wide-detector scanners and artificial intelligence (AI) models has enabled CCT to transition from a purely morphological tool to a modality capable of comprehensive, three-dimensional morpho-functional assessments. Methods: This narrative review evaluates the literature across Scopus, MEDLINE, and Web of Science regarding the calculation of biventricular function and EF using CCT. It provides an updated summary of current clinical applications, technological advancements, and comparative diagnostic reliability against TTE and CMR. Results: The CCT “one-stop-shop” concept allows for the simultaneous acquisition of anatomical data and systolic function metrics (EDV, ESV, SV, EF), optimizing clinical workflows at no additional cost. Being intrinsically three-dimensional, CCT bypasses the geometric assumptions and apical foreshortening artifacts typical of 2D-TTE, demonstrating high volumetric concordance with CMR. Nevertheless, structural limitations persist, primarily regarding ionizing radiation exposure, contrast media toxicity, dependence on heart rhythm stability, and lower temporal resolution compared to CMR. Conclusions: EF determination via CCT has achieved technical maturity and clinical validation. While it does not intend to replace TTE or CMR, it offers synergistic data when integrated with primary anatomical indications. Furthermore, AI integration has been shown to potentially automate this workflow, transforming CCT into an opportunistic screening tool for subclinical cardiac dysfunction.

Background: The management of localized prostate cancer (PCa) suffers from the dilemma between the overtreatment associated with radical surgery and the uncertainty of active surveillance, highlighting a significant therapeutic gap specifically for intermediate-risk patients and selected low-risk patients. Focal therapy (FT) emerges as an advanced technological solution to balance rigorous oncological control with anatomical and functional preservation. Methods: A narrative review of the literature was conducted to analyze the physical principles underlying various ablative energies (thermal, cryogenic, and non-thermal) as well as radiation-based focal approaches. The review examines the oncological rationale of targeted ablation, recent innovations in imaging, and the expanding clinical scenarios for FT application. Results: Evidence supports the oncological rationale of “Index Lesion” ablation as a targeted curative strategy for clinically significant disease, rather than merely a palliative one. The review highlights the emerging concept of “pushing the disease” and demonstrates the valuable role of salvage focal therapy in the setting of radio-recurrent carcinoma. Furthermore, recent innovations in multiparametric magnetic resonance imaging (mpMRI) and fusion systems have significantly refined patient selection, rendering this minimally invasive approach highly targeted. Conclusions: The current barrier to the universal adoption of focal therapy is the lack of a standardized consensus on the definitions of therapeutic failure and the inadequacy of traditional PSA-based criteria. However, evidence suggests that FT represents a promising, organ-sparing alternative for carefully selected patients with localized PCa, though long-term comparative data are still required.

Background: Right heart failure (HF) and tricuspid regurgitation (TR) are closely interrelated conditions, linked by a bidirectional and self-perpetuating pathophysiological relationship. Alterations in right-ventricular (RV) loading conditions, pulmonary vascular impedance, and ventriculo-arterial (VA) coupling play a central role in the development and progression of TR, which in turn exacerbates RV volume overload and end-organ dysfunction. Methods: This review provides a comprehensive overview of the pathophysiology of right HF and TR, focusing on the mechanisms underlying RV dysfunction, pressure–volume (PV) relationships, and pulmonary vascular load. We further examine the clinical implications of this interaction and summarize current strategies for risk stratification, with particular emphasis on disease-specific risk models. Results: TR emerges both as a consequence and a driver of RHF. Conditions such as pulmonary hypertension (PH) and left-sided heart disease promote annular dilation and leaflet tethering, leading to functional TR. Conversely, TR increases RV volume overload, worsening chamber dilation, reducing effective forward stroke volume (SV), and accelerating disease progression. This vicious cycle results in progressive RV impairment, impaired left-ventricular filling through ventricular interdependence, and systemic venous congestion affecting renal and hepatic function. Traditional risk scores fail to capture this complex pathophysiology. In this context, TRISCORE integrates clinical, biological, and echocardiographic (TTE) parameters reflecting RV dysfunction and systemic involvement, providing a more comprehensive assessment of disease severity and prognosis. Conclusions: TR should be considered not only a marker but also a key determinant of right HF progression. A multiparametric approach integrating pathophysiology and disease-specific risk stratification is essential to identifying the optimal therapeutic window and guiding clinical decision making.

While traditionally focused on coronary anatomy, cardiac computed tomography now enables non-invasive myocardial tissue characterization. By evaluating late iodine enhancement (LIE) and extracellular volume (ECV), single-energy CT (SECT) provides a valuable alternative to cardiac magnetic resonance for assessing ischemic and non-ischemic pathologies. However, clinical implementation of SECT faces technical challenges, primarily the low contrast-to-noise ratio (CNR) of iodine and the reliance on image subtraction for ECV quantification, both of which increase radiation exposure and susceptibility to spatial misregistration. To address these issues, protocol optimization is essential. Evidence-based recommendations include using low tube voltages to shift the X-ray spectrum closer to the iodine K-edge, paired with high reference tube currents. Additionally, delayed acquisition timing should be tailored to specific pathological targets to account for differences in contrast kinetics, and advanced iterative or deep learning image reconstructions should be implemented to mitigate noise. Optimized SECT demonstrates diagnostic and prognostic utility in conditions like acute myocardial infarction, hypertrophic cardiomyopathy, cardiac amyloidosis, and left ventricular thrombus detection. While spectral imaging represents the future, optimizing SECT through technical adjustments and standardized training is crucial for integrating myocardial characterization into routine workflows.

Spontaneous coronary artery dissection (SCAD) is the most common cause of myocardial infarction during pregnancy or the postpartum period and has a major impact on cardiovascular morbidity and death in pregnant women. A 38-year-old woman with sudden cardiac arrest ten days postpartum urgently underwent coronarography, which showed an intraparietal hematoma of the left anterior descending (LAD) artery. Two days later, coronary computed tomography angiography (CCTA) was performed, which showed the evidence of SCAD in the mid-distal tract of LAD and the presence of transmural ischemic infarction in the apex and mid antero-septal wall in delayed acquisition. The patient was treated with a beta-blocker. Four months later CCTA showed complete resolution of SCAD and evolution of the infarcted areas. Given the high accuracy and noninvasiveness of CCTA, our case highlights the potential role of this imaging modality in the diagnosis and follow-up of pregnancy associated SCAD.

The coronary arteries are a pair of arteries that branch off from the aorta and encircle the heart, providing oxygenated blood to the myocardium. Although coronary artery atherosclerosis remains a main cause of morbidity and mortality worldwide, coronary artery anomalies (CAAs) are increasingly recognized as a clinically relevant cause of ischemic events and can be subdivided into origin, course, or termination anomalies. The aim of this narrative review is to summarize the cross-sectional diagnostic imaging and clinical background of CAAs.
