Osborne-Grinter M, Ali A, Williams MC. Prevalence and clinical implications of coronary artery calcium scoring on non-gated thoracic computed tomography: a systematic review and meta-analysis. Eur Radiol 2024; 34:4459-4474. [PMID: 38133672 PMCID: PMC11213779 DOI: 10.1007/s00330-023-10439-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 08/02/2023] [Accepted: 09/07/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVES Coronary artery calcifications (CACs) indicate the presence of coronary artery disease. CAC can be found on thoracic computed tomography (CT) conducted for non-cardiac reasons. This systematic review and meta-analysis of non-gated thoracic CT aims to assess the clinical impact and prevalence of CAC. METHODS Online databases were searched for articles assessing prevalence, demographic characteristics, accuracy and prognosis of incidental CAC on non-gated thoracic CT. Meta-analysis was performed using a random effects model. RESULTS A total of 108 studies (113,406 patients) were included (38% female). Prevalence of CAC ranged from 2.7 to 100% (pooled prevalence 52%, 95% confidence interval [CI] 46-58%). Patients with CAC were older (pooled standardised mean difference 0.88, 95% CI 0.65-1.11, p < 0.001), and more likely to be male (pooled odds ratio [OR] 1.95, 95% CI 1.55-2.45, p < 0.001), with diabetes (pooled OR 2.63, 95% CI 1.95-3.54, p < 0.001), hypercholesterolaemia (pooled OR 2.28, 95% CI 1.33-3.93, p < 0.01) and hypertension (pooled OR 3.89, 95% CI 2.26-6.70, p < 0.001), but not higher body mass index or smoking. Non-gated CT assessment of CAC had excellent agreement with electrocardiogram-gated CT (pooled correlation coefficient 0.96, 95% CI 0.92-0.98, p < 0.001). In 51,582 patients, followed-up for 51.6 ± 27.4 months, patients with CAC had increased all cause mortality (pooled relative risk [RR] 2.13, 95% CI 1.57-2.90, p = 0.004) and major adverse cardiovascular events (pooled RR 2.91, 95% CI 2.26-3.93, p < 0.001). When CAC was present on CT, it was reported in between 18.6% and 93% of reports. CONCLUSION CAC is a common, but underreported, finding on non-gated CT with important prognostic implications. CLINICAL RELEVANCE STATEMENT Coronary artery calcium is an important prognostic indicator of cardiovascular disease. It can be assessed on non-gated thoracic CT and is a commonly underreported finding. This represents a significant population where there is a potential missed opportunity for lifestyle modification recommendations and preventative therapies. This study aims to highlight the importance of reporting incidental coronary artery calcium on non-gated thoracic CT. KEY POINTS • Coronary artery calcification is a common finding on non-gated thoracic CT and can be reliably identified compared to gated-CT. • Coronary artery calcification on thoracic CT is associated with an increased risk of all cause mortality and major adverse cardiovascsular events. • Coronary artery calcification is frequently not reported on non-gated thoracic CT.

Cardiac computed tomography-based assessment of mitral annular calcification in patients undergoing mitral transcatheter edge-to-edge repair. J Cardiovasc Comput Tomogr 2024; 18:26-32. [PMID: 38105119 DOI: 10.1016/j.jcct.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 11/27/2023] [Accepted: 12/10/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND The role of assessment of mitral annular calcification (MAC) using cardiac computed tomography (CCT) in mitral transcatheter edge-to-edge repair (TEER) remains unclear. The aim of this study was to investigate the association of MAC assessed by CCT with procedural and clinical outcomes in patients undergoing TEER. METHODS We retrospectively analyzed 275 patients who underwent pre-procedural CCT prior TEER. Mitral calcium volume (MCV) and MAC score were measured by CCT. Functional procedural success was defined as residual mitral regurgitation of ≤2+ with mean transmitral gradient of <5 mmHg at discharge. All-cause mortality within two years after TEER was collected. RESULTS MAC was present in 115 of 275 patients (41.8 %). The median MCV was 198 mm3 (interquartile range [IQR]: 84 to 863 mm3), and the median MAC score was 3 (IQR: 2 to 4). Higher MCV and MAC score were inversely related to the rate of functional procedural success, independently of anatomical features of mitral valve. Patients with moderate/severe MAC, defined as MAC score of ≥4, had a lower rate of functional procedural success than those without MAC (56.1 % vs. 81.3 %; p = 0.002). Moreover, higher MCV and MAC score were associated with a higher risk of all-cause mortality within two years, irrespective of baseline characteristics and functional procedural success. CONCLUSIONS The presence and burden of MAC assessed by CCT were associated with procedural and clinical outcomes in patients undergoing TEER. The CCT-based assessment of MAC may improve patient selection for TEER.

Abstract
Purpose To determine the impact of an artificial intelligence software predicting malignancy in the management of incidentally discovered lung nodules. Materials and methods In this retrospective study, all lung nodules ≥ 6 mm and ≤ 30 mm incidentally discovered on emergency CT scans performed between June 1, 2017 and December 31, 2017 were assessed. Artificial intelligence software using deep learning algorithms was applied to determine their likelihood of malignancy: most likely benign (AI score < 50%), undetermined (AI score 50-75%) or probably malignant (AI score > 75%). Predictions were compared to two-year follow-up and Brock's model. Results Ninety incidental pulmonary nodules in 83 patients were retrospectively included. 36 nodules were benign, 13 were malignant and 41 remained indeterminate at 2 years follow-up.AI analysis was possible for 81/90 nodules. The 34 benign nodules had an AI score between 0.02% and 96.73% (mean = 48.05 ± 37.32), while the 11 malignant nodules had an AI score between 82.89% and 100% (mean = 93.9 ± 2.3). The diagnostic performance of the AI software for positive diagnosis of malignant nodules using a 75% malignancy threshold was: sensitivity = 100% [95% CI 72%-100%]; specificity = 55.8% [38-73]; PPV = 42.3% [23-63]; NPV = 100% [82-100]. With its apparent high NPV, the addition of an AI score to the initial CT could have avoided a guidelines-recommended follow-up in 50% of the benign pulmonary nodules (6/12 nodules). Conclusion Artificial intelligence software using deep learning algorithms presents a strong NPV (100%, with a 95% CI 82-100), suggesting potential use for reducing the need for follow-up of nodules categorized as benign.

Novel 3D Echocardiographic Technique for Mitral Calcium Mapping. J Clin Med 2023; 12:jcm12041470. [PMID: 36836005 PMCID: PMC9959886 DOI: 10.3390/jcm12041470] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 02/07/2023] [Accepted: 02/10/2023] [Indexed: 02/16/2023] Open
Abstract
Mitral annular calcification (MAC) is a common chronic degenerative process of the mitral valve fibrous support ring. MAC increases the risk of mitral valve dysfunction, all-cause and cardiovascular mortality, and worse outcomes in cardiac interventions. Echocardiography represents the first imaging modality for MAC assessment, but it has low specificity compared to cardiac CT in terms of distinguishing between calcium and dense collagen. Novel three-dimensional transesophageal maximal intensity projection (MIP) mapping allows for the real-time MAC distribution and depth visualization of the cardiac anatomy and represents a useful and promising tool for pre-procedural assessment and intra-procedural guidance of cardiac interventions.

Abstract
With the continuous expansion of the disease scope of chest CT and cardiac CT, the number of these CT examinations has increased rapidly. In addition to their common indications, many incidental cardiac findings can be observed when carefully evaluating the coronary arteries, valves, pericardium, ventricles, and large vessels. These findings may have clinical significance or risk of complications, but they are sometimes overlooked or may not be described in the final reports. Although most of the incidental findings are benign, timely detection and treatment can improve the management of chronic diseases or reduce the possibility of severe complications. In this review, we summarized the imaging findings, incidence rate, and clinical relevance of some benign cardiac findings such as coronary artery calcification, aortic and mitral valve calcification, aortic calcification, cardiac thrombus, myocardial bridge, aortic dilation, cardiac myxoma, pericardial cyst, and coronary artery fistula. Reporting incidental cardiac findings will help reduce the risk of severe complications or disease deterioration and contribute to the recovery of patients.

Abstract
Amaç: Aşil tendonu (AT)- ultrasonografisi (US) ve gerinim elastografisi (SE) ile elde edilen AT- kalınlığı (T) ve AT- gerinim oranının (SR) mitral kapak kalsifikasyonlu (MAC) hastaları belirlemedeki önemini araştırmayı amaçladık.
Gereç ve Yöntem: Çalışmaya ekokardiyografi sonrası MAC tanısı alan 100 hasta (65 kadın, 35 erkek ve ortalama yaş 64.7 ± 12.1) ve kardiyovasküler risk faktörü benzer olan 50 kontrol (32 kadın, 18 erkek ve ortalama yaş 63.2 ± 12.8) alındı. Laboratuvar incelemeler ve AT US yapıldı. AT-T ve AT-SR hesaplandı.
Bulgular: MAC olan hastalarda AT-T ve AT-SR belirgin olarak yüksek olduğu bulundu. Logistic regresyon analizinde, AT-T ve AT-SR değerlerinin MAC olma riskini bağımsız olarak belirlediği bulundu. Bu analize göre AT-T (her 1 mm) ve AT-SR (her 0.1)’nin MAC olma riskini sırası ile %69.9 ve %12.7 oranlarında artırdığı saptandı. AT-T ve AT-SR değerlerinin MAC olan hastaları belirlemesi açısından ROC analizi yapıldığında, ROC eğri altında kalan alanın sırası ile 0.684 ve 0.819 belirlendi. Aynı analizde, AT-SR için sınır değer 1.25 olarak alındığında %94.1 sensitivite ve %76.2 spesivite ile MAC varlığını belirlediği tespit edildi.
Sonuç: AT SE incelemesinde saptanan AT-SR, MAC olan hastaları önceden belirlemede kullanılabilecek basit, ucuz, tekrarlanabilir ve non-invaziv bir parametredir. Bu durum MAC ve AT-SR artışının benzer fizyopatolojik mekanizma ile meydana gelebilmesinin bir sonucu olabilir.

Clinical Outcomes of Mitral Valve Disease With Mitral Annular Calcification. Am J Cardiol 2022; 174:107-113.

Abstract
The prevalence of mitral valve disease with mitral annular calcification (MAC) and its clinical outcomes remain uncertain. This study sought to evaluate the prevalence of significant mitral disease due to MAC, and the impact of intervention on the clinical outcomes in these patients. All patients who underwent transthoracic echocardiography (TTE) between January 2014 and December 2015 in our health care system were reviewed and identified for having MAC with significant mitral valve disease (i.e., either≥moderate mitral regurgitation (MR) or mitral stenosis (MS)). The primary endpoints of the study were all-cause mortality and a composite outcome of mortality or heart failure hospitalization at 3-year follow-up. Of 41,136 patients who underwent TTE, MAC was identified in 2,855 (6.9%) patients, including 434 (1.1% of total) patients who had significant MR and/or MS (median age [IQR], 80 [73 to 87] years; 63% women). MAC predominately involved the posterior annulus (95%), with the majority having calcification of both trigones (55%), the leaflets (71%), and circumferential involvement (67%). During 3-year follow-up, 59 (14%) patients underwent surgical or transcatheter MV intervention. Patients who did not undergo mitral intervention had higher all-cause mortality (HR 2.80, 95% CI 1.60 to 4.92; p <0.001) and a greater risk of the composite outcome (HR 1.43, 1.00 to 2.04; p = 0.05) than those treated. Survival at 3-year follow-up was markedly greater in those with mitral intervention (78% vs 50%; p <0.001). This survival benefit remained after multivariable adjustment. In conclusion, MAC affects approximately % of patients who undergo echocardiography. Those with significant mitral valve disease due to any degree of MAC have poor survival, which may be ameliorated with transcatheter or surgical intervention.

Abstract
Mitral annular calcification (MAC) represents an important risk factor in mitral valve (MV) surgery. Despite several procedures having been described, no surgical treatment of choice has been established so far: whether a decalcification should be systematically carried out, or if the MV should be preferentially repaired rather than replaced. A review of the literature on patients undergoing MV surgery associated with MAC was performed. Studies were excluded if dealing with endovascular procedures or emergency surgery for associated endocarditis. Case reports were also not considered in the final analysis. The literature search identified 1429 potentially eligible studies, and 25 papers were eventually included. Several surgical techniques were described to approach this challenging condition. During MV surgery, the presence of MAC favors the occurrence of suboptimal intraoperative outcomes. MAC-related complications such as atrioventricular groove rupture, cerebrovascular accident, new permanent pacemaker implantation, intraoperative conversion from valve repair to replacement and mortality were analyzed. MV surgery in the presence of MAC considerably impacts the postoperative outcomes in terms of morbidity and mortality. A great variability of surgical techniques is reported, suggesting the need for standardization of the approach.

Abstract
BACKGROUND Severe mitral annulus calcification (MAC) is believed to bear high operative and post-operative risk during mitral valve replacement (MVR) surgery, including longer surgery time, post-surgical valvular leaks and increased rate of embolic phenomena. We hypothesized that quantification of mitral calcium in pre-operative chest computerized tomography (CCT), performed to assess aortic root before cross-clamping may help in risk assessment of adverse intraoperative and postoperative outcomes in patients undergoing MVR. METHODS We included patients who underwent MVR between the years 2015 and 2018 at Poriya medical center. Preoperative CCT was performed using Philips iCT 256 and Agatston mitral annulus calcium score (MACS) was retrospectively calculated using Philips Intellispace portal version 8.0. Patients were divided into MACS quintiles; 1-3 quintiles were grouped (Low MACS) and compared to the 4-5 quintiles (High MACS) group for demographic, clinical operative and post-operative parameters. RESULTS A total of 66 patients had MVR, out of which 61% were males, with mean age of 64±9. Concomitant coronary or valvular procedures were done in 60% of patients. The median MACS was 43. High MACS (≥854) was not associated with longer bypass or cross clamp times. No differences in the MVR results were found between the groups. There were 6 post-operative embolic events; 1 mesenteric and 5 cerebral, which were not associated with MACS. CONCLUSION MACS did not seem to be related to adverse outcomes in MVR. Due to a low event rate and probable pre-selection of patients without extreme mitral annulus calcifications our results should be confirmed in larger prospective study.

Comparison of Clinical Characteristics, Natural History and Predictors of Disease Progression in Patients With Degenerative Mitral Stenosis Versus Rheumatic Mitral Stenosis. Am J Cardiol 2021; 143:118-124. [PMID: 33352211 DOI: 10.1016/j.amjcard.2020.12.026] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Revised: 12/02/2020] [Accepted: 12/07/2020] [Indexed: 11/21/2022]
Abstract
Mitral annular calcification (MAC) is a common echocardiographic finding and an increasingly recognized cause of degenerative mitral stenosis (DMS). However, little is known about the clinical characteristics and disease progression in DMS, particularly in comparison with rheumatic mitral stenosis (RMS). We retrospectively reviewed 203 consecutive patients with mitral stenosis (113 with DMS and 90 with RMS) who underwent echocardiography at our institution between January 2014 and December 2017. We compared the clinical characteristics and disease progression between the 2 groups. In addition, we analyzed the predictors of disease progression (defined as annual progression rate of a mean gradient >0 mm Hg/year) among patients with DMS. Patients with DMS were significantly older and had higher prevalence of atherosclerotic comorbidities than those with RMS. During the median follow-up period of 2.2 years, the annual progression rates were comparable (0.8 ± 0.8 mm Hg/year in DMS vs 1.0 ± 1.2 mm Hg/year in RMS; p = 0.32) and were highly variable (0.0 to 3.5 mm Hg/year in DMS and 0.0 to 5.5 mm Hg/year in RMS) within both groups among disease progression. In DMS patients, atherosclerotic comorbidities and lower initial mean gradient were significantly associated with disease progression even after adjustment by age and sex. There was no significant difference in the disease progression according to the circumferential MAC severity determined by echocardiography among DMS. In conclusion, DMS disease progression was slow but highly variable, similar to that of RMS. In patients with DMS, the baseline MAC severity did not correlate with disease progression, suggesting the importance of follow-up echocardiography regardless of the MAC severity.

Abstract
Objective Intracardiac thrombi are intermittently come across on cardiac computed tomography angiography (CCTA). This study aimed to examine the prevalence, outcome, and prognosis in patients with incidental found left-sided cardiac thrombi on CCTA. Material and Methods The Ethics Committee approved the present study of the Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand. A retrospective review of CCTA was performed for incidental left-sided cardiac thrombi. Results A total of 1080 CCTAs were enrolled with the prevalence of incidental left-sided cardiac thrombi is 4.53%. Of the 49 patients with CCTA incidental left-sided cardiac thrombi, 16 had left atrial thrombi, and 33 had left ventricular thrombi. All thrombi were undetermined before the CCTA, and their identification subsequently generated anticoagulation treatment. In 10 patients, embolic complications happened, 4 of which were fatal. Patients with incidental detected left-sided intracardiac thrombi seen by CCTA had more embolic event than patients who did not discover left-sided intracardiac thrombi by CCTA (HR = 8.07; 95% CI 1.48-44.06; p = 0.016). Conclusions Incidental left-sided cardiac thrombi on CCTA guided to management adjustments and seemed to present substantial mortality and morbidity in the present study. Physicians who interpret CCTA should ensure a dedicated effort not to disregard these prospective pitfalls.

Abstract
Background Computed tomography scans of the chest are often requested as a complementary examination to investigate a clinical suspicion of pulmonary disease caused by the novel coronavirus 19 (COVID-19). Objectives Our objective was to analyze the prevalence of incidental cardiovascular findings on chest CT scans requested to assess radiological signs suggestive of COVID-19 infection. Methods This cross-sectional, descriptive, and retrospective study reviewed 1,444 chest tomographies conducted in the Radiology department of the Hospital de Clínicas Gaspar Vianna, from March 1 to July 30, 2020, describing the prevalence of images suggestive of viral pneumonia by COVID-19 and incidental pulmonary and cardiovascular findings. Results The mean age of the patients was 50.6 ± 16.4 years and female sex was more frequent. Computed tomography without contrast was the most frequently used method (97.2%). Aortic and coronary wall calcification and cardiomegaly were the most prevalent cardiovascular findings. CT angiography revealed aortic aneurysms (9.7%), aortic dissection (7.3%) and thoracic aortic ulcers (2.4%). Conclusions Incidental cardiovascular findings occurred in about half of the chest CT scans of patients with suspected COVID-19, especially aortic calcifications, cardiomegaly, and coronary calcification.

Abstract
BACKGROUND Mitral annular calcification (MAC) has been associated with mitral valve (MV) disease and cardiovascular events in patients undergoing transcatheter aortic valve implantation (TAVI). We aimed to investigate the incidence and impact of mitral calcium volume (MCV) quantified by multidetector computed tomography (MDCT) on MV function and clinical outcomes after TAVI. METHODS Consecutive patients with exploitable echocardiography and MDCT performed during TAVI screening were enrolled in this retrospective analysis. Mitral calcium was assessed visually and measured using a semi-automatic tool developed for the aortic valve in an off-label fashion. RESULTS MCV >0 mm3 was found in 65% of the 875 included patients. Patients with calcification were older (82 ± 6 versus 81 ± 7; P = 0.002) and had high prevalence of renal dysfunction (69% versus 61%; P = 0.017) and mitral stenosis (25% versus 4%, P < 0.001). MCV correlated well with visual MAC severity (r = 0.94; P < 0.001), but showed a greater predictive value for mitral stenosis (AUC = 0.804 vs. 0.780, P = 0.012) , while it was not a predictor of mitral regurgitation (AUC = 0.514). Correlations were found between MCV and echocardiographic parameters including MV area, mean transmitral gradient, and pressure half-time (P < 0.001 for all). MCV did not impact on cardiovascular mortality or new permanent pacemaker implantation after TAVI. CONCLUSIONS Calcification of the mitral apparatus is common in TAVI candidates and results in mitral stenosis in 25% of the patients. Increasing MCV predicts mitral stenosis, but had no impact on clinical outcomes following TAVI. CLINICAL TRIAL REGISTRATION NCT01368250.

Abstract
BACKGROUND Epicardial adipose tissue (EAT) has been shown to be associated with diabetes mellitus (DM), hypertension (HT), coronary artery calcification, and atherosclerotic disease. Mitral annular calcification (MAC) is also associated with atherosclerosis. The purpose of this study was to assess the relationship between EAT and severe MAC. MATERIAL AND METHODS The study enrolled 102 patients who had severe MAC and 107 patients who did not have MAC, as determined by echocardiographic examination. EAT was measured by transthoracic echocardiography. The parasternal long-axis view was used to measure the maximal EAT thickness. RESULTS Patients with severe MAC were older (p<0.001) and were more likely to be female (p<0.001). Epicardial adipose tissue (p=0.001) and urea (p=0.004) were also higher and eGFR was lower (p<0.001) in patients with severe MAC. EAT (OR: 15.96, CI %: 1.04 - 24.604, p<0.05), female sex, CAD, DM, eGFR, and age were independent predictors of severe MAC. The AUC for the EAT to predict severe MAC was 0.699 (95%, CI: 0.625 - 0.774, p<0.001). CONCLUSIONS Our data suggest that EAT is an independent predictor for the presence of severe MAC. Routine echocardiographic assessment of EAT is a cheap and noninvasive method for evaluating patient cardiovascular risk classification.

Abstract
Mitral annulus calcification is a chronic degenerative process in the fibrous base of the mitral valve. Assessment and treatment of mitral valve disease in patients with severe mitral annulus calcification is challenging, and a multimodal approach is helpful to delineate its severity and anatomic features, and to guide the therapeutic strategy. This article reviews the current literature to provide a clinically relevant description of mitral annulus calcification, analyze the diagnostic pathway of a patient with mitral annulus calcification, and summarize the therapeutic options.

Abstract
Surgical mitral valve replacement in patients with severe annular calcification is a challenge for the cardiac surgeon. Surgical transatrial implantation of a transcatheter heart valve is an alternative for selected patients, in particular those at risk for obstruction of the left ventricular outflow tract or valve embolization. Herein, we review patient selection, surgical technique, and early outcomes after this novel hybrid procedure.

Abstract
Objective Incidental cardiac findings are often found on chest CT studies, some of which may be clinically significant. The objective of this pictorial review is to illustrate and describe the appearances and management of the most frequently encountered significant cardiac findings on non-electrocardiographically gated thoracic CT. Most radiologists will interpret multidetector chest CT and should be aware of the imaging appearances, significance, and the appropriate next management steps, when incidental significant cardiac disease is encountered on thoracic CT. Conclusion This article reviews significant incidental cardiac findings which may be encountered on chest CT studies. After completing this review, the reader should not only be familiar with recognizing clinically significant cardiac findings seen on thoracic CT examinations but also have the confidence to direct their further management.

Abstract
Cardiovascular disease risk increases in women after the menopausal transition; why this inflection point occurs remains uncertain. We aimed to characterize the influence of menopause on vascular aging by prospective assessment of change in indexes of subclinical atherosclerosis across the menopausal transition. We evaluated 411 healthy women from SWAN Heart, an ancillary study of SWAN (Study of Women's Health Across the Nation), for subclinical atherosclerosis at baseline and again after an average of 2.3 years. Carotid intima-media thickness and aortic pulse wave velocity were measured by ultrasound. Coronary artery calcium scores were obtained by computed tomography. Women were grouped by menopausal status as premenopausal, postmenopausal, or having undergone the transition during follow-up. Analyses of changes were adjusted for age at baseline and time between scans. Mean age at baseline was 51 ± 3 years; 93 (23%) subjects transitioned to menopause (Pre-Post), 147 (36%) remained premenopausal (Pre-Pre), while 171 (41%) were postmenopausal at baseline (Post-Post). Blood pressure readings did not differ between groups with similar increase noted in carotid intima-media thickness and log coronary artery calcium + 1 from baseline to follow-up. Change in aortic pulse wave velocity from baseline to follow-up was higher in Pre-Post (121 ± 23 cm/s) compared with Pre-Pre (38 ± 250 cm/s, p = 0.029) and Post-Post (41 ± 228 cm/s, p = 0.045). In conclusion, changes in aortic stiffness were more sensitive measures of perimenopausal vascular aging than morphologic indexes of subclinical atherosclerosis in women undergoing the menopausal transition. Serial assessment of such changes could potentially elucidate mechanisms of disease and identify women to target for aggressive lifestyle risk factor modification.

Abstract
PURPOSE Cardiac findings frequently remain unreported on non-electrocardiogram (ECG)-gated computed tomography (CT). Although the clinical relevance of such findings may be limited in a general patient population, they may have significant impact in intensive care patients. Thus, the purpose of this study was to evaluate the prevalence, underreporting, and clinical relevance of incidental cardiac findings in intensive care unit (ICU) patients. MATERIALS AND METHODS Non-ECG-gated chest CT examinations of ICU patients were retrospectively analyzed for incidental cardiac findings. The findings were classified into 3 categories (A to C): category A findings, which carry potential for risk to life; category B findings, which have a potential for significant morbidity; category C findings, which have a possible effect on prognosis. RESULTS A total of 500 patients who underwent non-ECG-gated thoracic CT examinations were included. Of the 500 patients, 403 presented with 1443 cardiac findings. Of all cardiac findings, 37% were described in the initial written report. Sixty category A findings were detected, of which 48% were not mentioned in the report. Six hundred forty category B findings were detected, of which 77% were not described in the report. The remaining 743 findings were classified as category C, 55% of which were not reported in the report. CONCLUSIONS The prevalence as well as the rate of underreporting of incidental cardiac findings in non-ECG-gated chest CT of ICU patients is very high. The results of this study underscore the importance of dedicated training for assessment of cardiac structures and conditions, which may be detected on non-ECG-gated chest CT.

Abstract
INTRODUCTION Computed tomographic pulmonary angiograms (CTPAs) are often ordered to evaluate pulmonary embolism (PE) in the emergency department (ED). The increase use of CTPA has led to an increase in incidental findings, often of low clinical significance. Our objectives were to (1) assess the prevalence and clinical significance of incidental findings identified in patients evaluated with CTPAs for PE in the ED, (2) evaluate follow-up investigations for these incidental findings, and (3) assess the utility of routine chest X-rays done prior to CTPA. METHODS This is a historical cohort study of adult patients, presenting to two tertiary care EDs from January-December 2015, evaluated with CTPA for possible PE. Two reviewers' extracted data from electronic CT records in a standardized fashion with inter-rater reliability reported using the kappa statistic. We measured the prevalence of PE and stratified non-PE findings according to alternative diagnoses and incidental findings. Data were reported as mean and standard deviation (SD). Univariate analyses were performed with t test for continuous variables. RESULTS A total of 1708 studies were included (mean 62 years (SD 16.7), 56.9% female). PE was found in 233 (13.6%) patients. A total of 223 (13.1%) patients had an incidental finding, the majority of which included pulmonary nodules (n = 83, 37.2%) and adenopathy (n = 26, 11.6%). Of the incidental findings, 197 (88.3%) were non-significant and led to no definitive diagnosis of cancer. In patients who underwent both CTPA and chest X-ray, X-ray reports revealed the same diagnosis in 77% of PE-negative patients without missing a clinically significant incidental finding. CONCLUSIONS Incidental findings are as common as a diagnosis of PE in patients undergoing CTPA. They are rarely clinically significant. Chest radiograph remains a reasonable initial investigation as it can aid in identifying alternative diagnoses especially in the setting of a low pre-test probability for PE.

Abstract
Aims Calcified aortic stenosis (AS) and mitral annular calcification (MAC) have certain similar etiology and pathophysiological mechanisms. MAC is frequently encountered in pre-procedural computed tomography (CT) imaging of patients that undergo transcatheter aortic valve replacement (TAVR), but its prognostic implications for these patients have not been thoroughly investigated. This study sought to evaluate the prevalence of MAC among patients with severe AS and to assess the clinical implications of MAC on these patients during and following TAVR. Methods and results Consecutive patients that underwent TAVR were compared according to the existence of MAC and its severity in pre-TAVR CT scans. From the entire cohort of 761 patients, 49.3% had MAC, and 50.7% did not have MAC. Mild MAC was present in 231 patients (30.4%), moderate MAC in 72 patients (9.5%), and severe MAC in 72 patients (9.5%). Thirty-day mortality and major complications were similar between patients with and without MAC. In a multivariable survival analysis, severe MAC was found to be an independent strong predictor of overall mortality following TAVR (all-cause mortality: hazards ratio [HR] 1.95, 95% confidence interval [CI] 1.24-3.07, P = 0.004; cardiovascular mortality: HR 2.35, 95% CI 1.19-4.66; P = 0.01). Severe MAC was also found to be an independent strong predictor of new permanent pacemaker implantation (PPI) after TAVR (OR 2.83, 95% CI 1.08-7.47; P = 0.03). Conclusion Half of the patients with severe AS evaluated for TAVR were found to have MAC. Severe MAC is associated with increased all-cause and cardiovascular mortality and with conduction abnormalities following TAVR and should be included in future risk stratification models for TAVR.

Abstract
Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features.

Abstract
The aim of the study was to estimate the rate of incidental cardiac findings (ICF) in patients undergoing noncardiac chest CT.An experienced radiologist retrospectively reviewed 237 consecutive patients (147 males and 90 females with median age of 69 years) undergoing a noncardiac chest CT. ICF at targeted review were compared to those mentioned in original reports (χ test).At review, ≥1 ICF was detected in 124/237 patients (52%), for a total of 229 ICF, 158 of them (69%) not originally mentioned. Valvular calcifications were unmentioned in 23/23 (100%) patients, main pulmonary artery dilation in 21/22 (96%), coronary calcifications in 69/86 (80%), right or left atrial dilation in 7/11 (64%), aortic atherosclerosis in 29/62 (47%), and ascending aorta dilatation in 8/18 (44%). All 6 pericardial effusions were originally mentioned. No association with sex (P ≥ .189); positive correlation with age (P < .001).Half of patients undergoing noncardiac chest CT presented ≥1 ICF, independently from sex but increasing with age. Moreover, 69% of detectable ICFs were not originally mentioned.

Abstract
BACKGROUND AND METHOD Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. RESULTS The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. CONCLUSION The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance.

Abstract
We evaluated the frequency and subtypes of clinically relevant cardiovascular (CV) findings identified on staging computed tomography (CT) in a large sample. Patients (n = 5026) with different malignant diseases were staged by CT. Clinically relevant CV findings (CRCFs) were included into the study. The CRCFs were defined as cardiac aneurysm, cardiac thrombus, venous thrombosis, arterial thrombosis, arterial dissection, pulmonary thromboembolism, arterial dissection, and dislocation of venous ports/central venous catheters. The CRCFs were identified in 342 patients (6.8% of all patients). Overall, 491 CRCFs were identified in the patients (1.4 per patient). In 203 (59.4%) patients, 1 CRCF; in 129, 2 (37.7%) CRCFs; and in 10 (2.9%) cases, 3 CRCFs were detected. There were incidental venous thrombosis (n = 298, 60.7% of all CRCFs), pulmonary thromboembolism (n = 84, 17.1%), arterial aneurysms (n = 44, 8.9%), arterial thrombosis (n = 43, 8.8%), heart thrombus (n = 15, 3.1%), arterial dissection (n = 3, 0.6%), heart aneurysms (n = 2, 0.4%), and port catheter dislocation (n = 2, 0.4%). The identified CRCF can be associated with potential hazardous complications. The CV system should be carefully evaluated in staging CT investigations.

Abstract
A 65-year-old man with known bone metastases from prostate cancer and no cardiac history attended for a restaging bone scan (BS). Diffuse increased Tc-HDP activity in the heart was noted, new since a BS 3 months earlier. A restaging contrast-enhanced CT scan on the same day showed reduced myocardial perfusion in the anterior, apical, and septal walls. On direct questioning, he described an episode of severe exertional chest pain the day before. Myocardial infarction was confirmed and treated with primary percutaneous coronary intervention. New cardiac uptake on BS, raising the possibility of myocardial infarction, is a red alert for clinicians.

Abstract
BACKGROUND Cardiac myxomas are sources of systemic embolism. Currently a large volume of chest CT and calcium-scoring CT scans are performed without contrast injection. PURPOSE To evaluate the diagnostic capability of non-contrast CT covering heart in detecting cardiac myxomas. MATERIAL AND METHODS This retrospective study included 36 non-contrast CT scans of 36 consecutive patients (16 men, 20 women) who underwent CT scan before surgery for left atrial myxomas and 20 patients without myxoma as a control group. Two independent readers who were blinded to medical information reviewed non-contrast CT scans of 36 patients with cardiac myxomas and 20 scans in the control group patients. They determined the presence of lesions suspicious of myxomas using a five-point scale. The other reader measured attenuation number in the non-calcific areas of the tumors and sizes of the masses on the non-contrast CT images. RESULTS The average attenuation of cardiac myxoma (22.5 Hounsfield units [HU]; range, 8.9-32.9 HU) and adjacent unopacified blood (44.6 HU; range, 31.5-57 HU) were significantly different (P < 0.001). Twelve cardiac myxomas (31.6%) had internal calcification and all of them were detected by both of readers. Cardiac myxomas were measured smaller on non-contrast CT (mean, 3.5 cm; range, 1.1-9.7 cm) than on pathologic specimens (mean, 4.1 cm, 1.4-10.0 cm) (P < 0.001). Considering grade 3-5 on a five-grade scale as the detectability, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of non-contrast CT in detecting cardiac myxomas were 88.8%/86.1%, 95.0%/100%, 96.9%/100%, 82.6%/80.0%, and 91.1%/91.1%, by reader 1 and reader 2, respectively and there was good inter-observer reliability (kappa value = 0.92, P = 0.157). CONCLUSION Non-contrast CT scan is useful for detecting cardiac myxomas. Therefore, radiologists should be familiar with imaging findings of cardiac myxomas on non-contrast CT.

Abstract
The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.
