Infective endocarditis (IE) is a life-threatening condition with a rising incidence, demanding rapid and precise diagnosis. While echocardiography remains the cornerstone of initial evaluation, its limitations in complex cases—such as those involving prosthetic valves or cardiac devices—are well-known. This review synthesizes current evidence and guidelines to outline a practical, multimodality imaging approach for IE. We emphasize that integrating advanced techniques like cardiac computed tomography (CT) and [18F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) early in the diagnostic pathway, particularly in high-risk scenarios, significantly enhances diagnostic certainty, guides therapeutic decisions, and improves patient outcomes. A tailored imaging strategy, driven by clinical presentation and integrated within a multidisciplinary endocarditis team, is paramount for modern IE management.
Background and Objectives: Cardiac magnetic resonance (CMR) imaging has become an essential instrument in the study of cardiomyopathies; it has recently been integrated into the diagnostic workflow for cardiac amyloidosis (CA) with remarkable results. An additional emerging role is the stratification of the arrhythmogenic risk by scar analysis and the possibility of merging these data with electro-anatomical maps. This is made possible by using a software (ADAS 3D, Galgo Medical, Barcelona, Spain) able to provide 3D heart models by detecting fibrosis along the whole thickness of the myocardial walls. Little is known regarding the applications of this software in the wide spectrum of cardiomyopathies and the potential benefits have yet to be discovered. In this study, we tried to apply the ADAS 3D in the context of CA. Materials and Methods: This study was a retrospectively analysis of consecutive CMR imaging of patients affected by CA that were treated in our center (Marche University Hospital). Wherever possible, the data were processed with the ADAS 3D software and analyzed for a correlation between the morphometric parameters and follow-up events. The outcome was a composite of all-cause mortality, unplanned cardiovascular hospitalizations, sustained ventricular arrhythmias (VAs), permanent reduction in left ventricular ejection fraction, and pacemaker implantation. The secondary outcomes were the need for a pacemaker implantation and sustained VAs. Results: A total of 14 patients were deemed eligible for the software analysis: 8 patients with wild type transthyretin CA, 5 with light chain CA, and 1 with transthyretin hereditary CA. The vast majority of imaging features was not related to the composite outcome, but atrial wall thickening displayed a significant association with both the primary (p = 0.003) and the secondary outcome of pacemaker implantation (p = 0.003). The software was able to differentiate between core zones and border zones of scars, with the latter being the most extensively represented in all patients. Interestingly, in a huge percentage of CMR images, the software identified the highest degree of core zone fibrosis among the epicardial layers and, in those patients, we found a higher incidence of the primary outcome, without reaching statistical significance (p = 0.18). Channels were found in the scar zones in a substantial percentage of patients without a clear correlation with follow-up events. Conclusions: CMR imaging plays a pivotal role in cardiovascular diagnostics. Our analysis shows the feasibility and applicability of such instrument for all types of CA. We could not only differentiate between different layers of scars, but we were also able to identify the presence of fibrosis channels among the different scar zones. None of the data derived from the ADAS 3D software seemed to be related to cardiac events in the follow-up, but this might be imputable to the restricted number of patients enrolled in the study.
Background: Left ventricular noncompaction (LVNC) is a myocardial abnormality char-acterized by prominent trabeculations, a thin compacted layer, and deep intertrabecular recesses. LVNC is a heterogeneous myocardial disorder of uncertain etiology, which may occur as a congenital or acquired condition or develop in association with other cardio-myopathies. Genetic factors have also been implicated in its pathogenesis. Objectives: The aim of this study was to investigate the genetic background of patients with LVNC through next-generation sequencing (NGS) analysis and to identify potentially dis-ease-associated variants. Methods: Twenty-five patients with LVNC underwent genetic testing by NGS using the Ion Torrent™ platform. Variants identified by NGS were con-firmed by Sanger sequencing. The interpretation was performed according to ACMG guidelines using multiple bioinformatic and clinical databases. Results: Genetic variants were identified in 13 patients, with 14 variants detected in 9 genes (TTN, MYH7, CTNNA3, DSG2, FLNC, JPH2, NKX2-6, TNNC1, and JUP). Eight variants (57%) were nov-el, four (29%) had been previously reported in clinical cases without scientific discussion, and two (14%) were already described in the literature. According to ACMG criteria, vari-ants were classified as pathogenic (n=1), likely pathogenic (n=7), or variants of uncertain significance (n=5). Conclusions: These findings highlight the marked genetic heterogenei-ty of LVNC and support the role of genetic testing in improving diagnosis, risk stratifica-tion and clinical management.
