Higher coronary artery calcium score is associated with increased risk of atrial fibrillation recurrence after catheter ablation
Coronary artery calcium score (CACS) is associated with an increased risk of atrial fibrillation (AF) development, but scarce data are available regarding the impact on AF recurrence. This study aims to assess the impact of CACS on AF recurrence following catheter ablation.Prospective evaluation of the learning curve and diagnostic accuracy for Pre-TAVI cardiac computed tomography analysis by cardiologists in training: The LEARN-CT study
To investigate the learning curve and the minimum number of cases required for a cardiologist in training to acquire the skills to an accurate pre-TAVI cardiac CT (CCT) analysis using a semi-automatic software.CT Evaluation by Artificial Intelligence for Atherosclerosis, Stenosis and Vascular Morphology (CLARIFY): A Multi-center, international study
Atherosclerosis evaluation by coronary computed tomography angiography (CCTA) is promising for coronary artery disease (CAD) risk stratification, but time consuming and requires high expertise. Artificial Intelligence (AI) applied to CCTA for comprehensive CAD assessment may overcome these limitations. We hypothesized AI aided analysis allows for rapid, accurate evaluation of vessel morphology and stenosis.Accelerating the future of cardiac CT: Social media as sine qua non?
The vision for the Journal of Cardiovascular Computed Tomography's social media efforts is to amplify the impact of the Journal while driving engagement, increasing journal visibility and disseminating content to new audiences globally. Serving as “the front door” to the Journal, this digital evolution represents an important step forward for a field in which advancements in hardware, image processing and clinical evidence have evolved rapidly. However, is social media the panem et circenses of cardiovascular computed tomography (CT), that of superficial appeasement, or of sine qua non; an essential ingredient to the acceleration of the Journal and of the field of cardiovascular CT? This paper aims to present the initial impact of social media within a dedicated cardiovascular CT journal.Subvalvular pannus and thrombosis in a mitral valve prosthesis
A 69-year-old female underwent cardiac CT to evaluate prosthetic valve (PHV) dysfunction detected on echocardiography. A CT coronal and en face views of the mitral annular plane showed a low-density, mass-like lesion on the left atrial side of the PHV and a high-density, plate-like lesion on the left ventricular side of PHV. A repeat of the mitral valve replacement was performed, and preoperative CT findings of both the thrombus on the left atrial side and pannus formation on the LV side were confirmed in the operative findings.Cardiopulmonary manifestations of isolated pulmonary valve infective endocarditis demonstrated with cardiac CT
Right-sided infective endocarditis involving the pulmonary valve is rare. This pictorial essay discusses the use and findings of cardiac CT combined with delayed chest CT and noncontrast chest CT of pulmonary valve endocarditis. Cardiac CT is able to show the full spectrum of right-sided endocarditis cardiopulmonary features including manifestations that cannot be demonstrated by echocardiography.Coronary CT angiography for chest pain in pseudoxanthoma elasticum and cardiac intervention management
We describe the case of a rare cause of severe coronary artery disease in a young woman without cardiovascular risk factors. Cardiac CT played an important role in diagnosis and cardiac management including coronary intervention.Multimodality imaging of multivalvular endocarditis after transcatheter aortic valve replacement
Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgery for severe aortic stenosis in non-operable and high surgical risk patients. While endocarditis following TAVR is rare, the significant co-morbidities commonly found in this patient population can complicate evaluation and management. A case of TAVR endocarditis initially diagnosed by cardiac computed tomography angiography and confirmed with transesophageal echocardiogram is presented. In addition to demonstrating the appearance of vegetations and perivalvular involvement in endocarditis complicating TAVR, this case illustrates the utility of cardiac CT techniques in imaging suspected TAVR endocarditis.Case of double-outlet right ventricle after repair with pulmonary arteriovenous malformations using cardiac CT
We present a case where cardiac CT clearly defines the complex anatomy of a 22 year old man with double outlet right ventricle who is status bilateral bidirectional Glenn and Fontan conduit. This case also shows the association of pulmonary arteriovenous malformations with Fontan and Glenn procedures.Multimodality imaging of an adult with Shone complex
Shone complex is a rare combination of valvular or supravalvular aortic stenosis, supra-valvular mitral membrane, parachute mitral valve, and coarctation of the aorta. This article presents an unusual case of a 40-year-old woman who presented with a history of progressive dyspnea. We describe the main imaging features and protocol used for visualizing this syndrome using various imaging modalities.Evaluation of valvular disease by cardiac computed tomography assessment
Cardiac multidetector computed tomography (MDCT) angiography is emerging as a technique to evaluate cardiac valve structure and function. MDCT can provide insights into cardiac valve anatomy and pathologic states, including comparable efficacy in valve area and regurgitant orifice area assessment compared with echocardiography and magnetic resonance imaging. MDCT can also be useful when initial evaluation of valvular disease with echocardiography yields suboptimal images. MDCT provides concurrent visualization of coronary anatomy which may avoid the need for further invasive preoperative testing.Turner Syndrome with aberrant right subclavian artery and partial anomalous pulmonary venous return
We report the case of a 6 year old girl with Turner Syndrome and Aberrant Right Subclavian Artery with an incidental finding of PAPVR on contrast-enhanced, high-pitch, 128-slice, electrocardiographic-gated dual source CT. There is value of using high-pitch DSCT in pediatric patients for diagnostic images with minimal radiation exposure.Ventricular septal rupture and right ventricular intramyocardial dissection secondary to acute inferior myocardial infarction
A 61-year-old female patient presented with sub acute myocardial infarction with an occluded right coronary artery on invasive evaluation and a ventricular septal rupture on echocardiogram. Cardiac computed tomography (CT) was performed to better define the septal anatomy. As the anatomy on cardiac CT was considered unfavorable for percutaneous intervention, the patient underwent successful surgical repair.
