- Abstract
Background: Cardiac disease is the leading cause of maternal mortality in developed countries, and myocardial infarction (MI) is an important cause of pregnancy-associated morbidity and mortality. These infrequent, but very serious, events are not optimally described in the medical literature., Objectives: This study describes a 15-year consecutive, retrospective cohort of confirmed pregnancy-associated MIs (PAMIs) identified in Alberta, Canada (2003-2017)., Methods: Utilizing a provincial administrative database, a cohort of women with PAMI were identified using a validated algorithm. Additional cases were identified by reviewing provincial maternal mortality records. Medical record review was conducted on each case with further details obtained via linkage with a provincial coronary heart disease registry. Available angiographic images were also reviewed., Results: Forty-three cases of PAMI were identified in Alberta between 2003 and 2017, providing a crude incidence of ∼5.64/100,000 births. Rates of PAMI increased over the study period. Of the identified MIs, 16.3% occurred antepartum (mean gestational age of 18 weeks), while 30.2% were peripartum and 53.4% occurred within 6 months postpartum (at a mean of 7.8 weeks after delivery). The most common mechanism of PAMI was spontaneous coronary artery dissection (44.2%) and this mechanism predominated postpartum. Coronary artery disease was a frequent antepartum cause of MI, whereas demand ischemia was the leading cause of peripartum MI. Maternal mortality was approximately 9%., Conclusions: PAMI is an increasing cause of maternal morbidity and mortality in Alberta. Clinicians should have a high index of suspicion for PAMI and ensure optimal management of this dangerous complication of pregnancy., Competing Interests: The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (© 2025 The Authors.)

- Abstract
Despite enormous strides in our field with respect to patient care, there has been surprisingly limited dialogue on how to train and educate the next generation of congenital cardiologists. This paper reviews the current status of training and evolving developments in medical education pertinent to congenital cardiology. The adoption of competency-based medical education has been lauded as a robust framework for contemporary medical education over the last two decades. However, inconsistencies in frameworks across different jurisdictions remain, and bridging gaps between competency frameworks and clinical practice has proved challenging. Entrustable professional activities have been proposed as a solution, but integration of such activities into busy clinical cardiology practices will present its own challenges. Consequently, this pivot towards a more structured approach to medical education necessitates the widespread availability of appropriately trained medical educationalists, a development that will better inform curriculum development, instructional design, and assessment. Differentiation between superficial and deep learning, the vital role of rich formative feedback and coaching, should guide our trainees to become self-regulated learners, capable of critical reasoning yet retaining an awareness of uncertainty and ambiguity. Furthermore, disruptive innovations such as "technology enhanced learning" may be leveraged to improve education, especially for trainees from low- and middle-income countries. Each of these initiatives will require resources, widespread advocacy and raised awareness, and publication of supporting data, and so it is especially gratifying that Cardiology in the Young has fostered a progressive approach, agreeing to publish one or two articles in each journal issue in this domain.

- Abstract
Background: Webinars have recently replaced in-person medical conferences, including paediatric cardiology conferences, given the COVID-19 pandemic., Methods: With increasing environmental concerns, we analysed the differences between the environmental footprint of a paediatric cardiology webinar with a hypothetical conference. Travel data was collected, with assumptions made on the amount of computer use, internet use and accordingly the overall use of electricity for both forms of conference. Life Cycle Assessment methodology was used (OpenLCA and Ecovinvent v 3.7)., Results: We showed that the theoretical environmental impact of a virtual conference is significantly less (4 tons CO2 equivalent) than the traditional international face-to-face conference (192 tons CO2 equivalent). The life cycle assessment methodology showed that resource use for a face-to-face conference lasting 2.5 days for 1374 attendees is equivalent to 400 times what an average person would use in one year, the climate change and photochemical ozone formation approximately 250 times and the eutrophication terrestrial equivalent to 225 times. However, using carbon equivalent emissions to measure environmental harm from flying is an under estimate of the potential damage, when one considers the additional production of airplane contrails. Notwithstanding this, there is a 98% reduction in climate change impact when meetings are held virtually., Conclusions: While the virtual conference may never completely replace the traditional in-person paediatric cardiology conference, due to networking benefits, the significant theoretical benefits to the environment highlighted in this study, warrants consideration for the virtual conference taking a more common place in sustainable academia.

- Abstract
Objective: This study investigated the impact of the Webinar on deep human learning of CHD., Materials and Methods: This cross-sectional survey design study used an open and closed-ended questionnaire to assess the impact of the Webinar on deep learning of topical areas within the management of the post-operative tetralogy of Fallot patients. This was a quantitative research methodology using descriptive statistical analyses with a sequential explanatory design., Results: One thousand-three-hundred and seventy-four participants from 100 countries on 6 continents joined the Webinar, 557 (40%) of whom completed the questionnaire. Over 70% of participants reported that they "agreed" or "strongly agreed" that the Webinar format promoted deep learning for each of the topics compared to other standard learning methods (textbook and journal learning). Two-thirds expressed a preference for attending a Webinar rather than an international conference. Over 80% of participants highlighted significant barriers to attending conferences including cost (79%), distance to travel (49%), time commitment (51%), and family commitments (35%). Strengths of the Webinar included expertise, concise high-quality presentations often discussing contentious issues, and the platform quality. The main weakness was a limited time for questions. Just over 53% expressed a concern for the carbon footprint involved in attending conferences and preferred to attend a Webinar., Conclusion: E-learning Webinars represent a disruptive innovation, which promotes deep learning, greater multidisciplinary participation, and greater attendee satisfaction with fewer barriers to participation. Although Webinars will never fully replace conferences, a hybrid approach may reduce the need for conferencing, reduce carbon footprint. and promote a "sustainable academia".

- Abstract
Background: The primary mode of imaging in hypertrophic cardiomyopathy (HCM) is transthoracic echocardiography (TTE). However, in adults inadequate acoustic windows lead to poor quantification of myocardial thickness compared with cardiac magnetic resonance (CMR) imaging. In comparison, children have better acoustic windows and TTE measurements of wall thickness might be more accurate. The aim of this study was to assess the performance of TTE compared with CMR for the assessment of myocardial thickness in children with HCM., Methods: Nineteen children (median age, 12.7 years; range, 8.4-18.4 years) with known HCM were studied using TTE and CMR imaging on the same day. The left ventricle was measured off-line using the standard 16-segment model., Results: With CMR imaging 304 (19 × 16) segments were analyzable whereas only 263 were analyzable using echocardiography. Wall thickness measurements according to TTE were greater than those according to CMR imaging in the basal anterolateral, midventricular anterior and anterolateral and apical inferior, lateral and septal segments and smaller for the midventricular inferior and inferoseptal segments. Reproducibility of CMR and TTE measurements was assessed using the intraclass correlation coefficient (ICC). CMR measurements showed excellent intrareader (ICC, 0.929-0.991) and moderate inter-reader (ICC range, 0.512-0.991) reproducibility. TTE measurements revealed moderate intrareader (ICC, 0.575-0.942) and poor inter-reader (ICC range, -1.02 to 0.939) reproducibility., Conclusions: Echocardiography incompletely assesses circumferential myocardial thickness in a proportion of pediatric patients with HCM. Echocardiography under- and overestimates maximum wall thickness compared with CMR, depending on the location. Measurements using CMR are more reproducible than those obtained using echocardiography., (Copyright © 2016 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: While well characterized in adult patients, the pattern of hypertrophy and the extent of myocardial scarring in hypertrophic cardiomyopathy (HCM) are insufficiently known. The aim of this study was to assess the hypertrophy patterns and the prevalence and clinical significance of scars in the hearts of young patients with HCM., Methods and Results: A retrospective analysis of the imaging findings of 38 children (aged 12.83 ± 2 years, 30 males) with HCM who underwent cardiac magnetic resonance imaging (CMR) was performed. In addition to left ventricular mass and volumes, the examinations were assessed for the pattern of hypertrophy and presence of late gadolinium enhancement (LGE). A myocardial signal intensity ≥6 standard deviations above the mean of normal myocardium defined positive LGE. Left ventricular mass index averaged 110 ± 34 g/m(2) . Nineteen children (50%) had diffuse septal, 13 (34%) diffuse concentric and 6 (16%) isolated basal hypertrophy. Seven children (18%) had LGE. Patients with LGE had a greater left ventricular mass index than those without (136 ± 34 g/m(2) vs. 104 ± 31 g/m(2) , P = .025). The only two patients who presented with an episode of aborted sudden cardiac death had LGE (P = .03)., Conclusions: The most common hypertrophy pattern in children with HCM was diffuse septal hypertrophy. The incidence of LGE observed is lower than that reported in adults. The presence of LGE appears to confer a risk for adverse events., (© 2015 Wiley Periodicals, Inc.)

- Abstract
In women with valvular heart disease, pregnancy-associated cardiovascular changes can contribute to maternal, foetal and neonatal complications. Ideally, a woman with valvular heart disease should receive preconception assessment and counselling from a cardiologist with expertise in pregnancy. For women with moderate- and high-risk valve lesions, appropriate risk stratification and management during pregnancy will optimise outcomes. Pregnancy in women with high-risk lesions, such as severe aortic stenosis, severe mitral stenosis and those with mechanical valves, requires careful planning and coordination of antenatal care by a multidisciplinary team. The purpose of this overview is to describe the expected haemodynamic changes in pregnancy, review pregnancy risks for women with valvular heart disease and discuss strategies for management., (Copyright © 2014.

- Abstract
To assess the impact of aortic root asymmetry on the relationship between aortic dimensions derived from two-dimensional transthoracic echocardiography (TTE) as compared with cross-sectional cardiovascular magnetic resonance (CMR) imaging in adults with a bicuspid aortic valve (BAV). Maximal CMR cross-sectional aortic measurements at the level of the sinuses of Valsalva, including cusp-commissure, cusp-cusp diameters and aortic root areas, from 68 consecutive patients (65% male) were retrospectively analyzed. The degree of aortic root asymmetry on CMR was expressed using the coefficient of variance of the root diameters in each dimension for an individual (CoeffVi) as compared with the median of the entire population (CoeffVp) and asymmetry was defined as CoeffVi > CoeffVp. Values obtained from CMR were compared with standard root measurements using TTE from contemporary studies (48 patients, 71%). Reproducibility of CMR measurements was assessed using the intra-class correlation coefficient (ICC). Echocardiography systematically underestimated aortic root dimensions in comparison with CMR, particularly in asymmetric roots with cusp-cusp measurements in systole (bias: -4.9 mm). Best agreement between modalities existed in symmetric roots with cusp-commissure measurements in diastole (bias: -0.01 mm). CMR measurements showed excellent intra-reader (ICC ≥ 0.98) and moderate inter-reader (ICC range 0.37-0.95) reproducibility, particularly aortic root area (inter/intra-reader ICC ≥ 0.94). In comparison to cross-sectional CMR diameters, standard TTE measurements consistently underestimates maximum aortic root diameter in adults with a BAV and aortic root asymmetry further decreases the agreement between CMR and TTE. CMR-derived aortic root measurements are reproducible and aortic root area showed the best reproducibility.

- Abstract
Advances in pediatric surgical and interventional techniques and medical care over the past 50 years have revolutionized the care of children with congenital heart disease. Survival to adulthood is now expected and, as such, there is a growing population of adults which is exceeding the pediatric population with congenital heart disease. Noninvasive cardiac imaging with modalities such as echocardiography, computed tomography, and cardiac magnetic resonance imaging are integral to the care of adults with congenital heart disease. These modalities are used for diagnosis, surveillance for complications late after surgery and catheter-based interventions, and in decision-making for medical, interventional, and surgical therapies. In this review we will discuss noninvasive imaging modalities used to assess congenital cardiac lesions, imaging strategies for select congenital lesions, and comment on the future of cardiac imaging in congenital heart disease., (Copyright © 2013 Canadian Cardiovascular Society.

- Abstract
We present the case of a 22-year-old man with a Fontan circulation who suffered from intractable protein losing enteropathy for an 8-year period necessitating several hospital admissions for recurrent pleural effusions and edema. Despite trying several recognized medical therapies to alleviate his protein losing enteropathy, his condition did not improve until the introduction of loperamide for troublesome diarrhea. Following this, his symptoms and serum albumin improved dramatically and he has not required any further hospital admissions at 22 months follow up., (© 2011 Copyright the Authors.

- Abstract
Background: Inflammatory markers are increased in chronic heart failure (CHF), including high-sensitivity C-reactive protein (hsCRP), but there is little information on its relationship to prognosis or other prognostic markers. We aimed to investigate the relationship between hsCRP and prognosis in patients with CHF and left ventricular systolic dysfunction (LVSD)., Methods: Patients with CHF and LVSD (n = 957), but without infection or inflammatory disease, were identified. Patients had their medical history taken, underwent physical examination, had electrocardiographic and echocardiographic assessment, and had a 6-minute corridor walk test (6MWT) and blood tests, including hsCRP and N-terminal pro-B natriuretic peptide (NT-pro-BNP)., Results: Patients with worse New York Heart Association class (P = .02), shorter 6-minute corridor walk test distance (P < .001), higher NT-pro-BNP levels (P < .001), anemia (P < .001), and renal dysfunction (P < .001), but not lower LV ejection fraction, had higher plasma concentrations of hsCRP. Patients with a CRP of >11.0 pg/mL had a hazard ratio for death of 3.0 compared with those with a CRP of <2.8 pg/mL (P < .001). Of 402 patients who had a second sample taken for hsCRP at 1 year, 46% showed a substantial change from baseline levels. Marked increases in hsCRP were associated with a fall in hemoglobin level. NT-pro-BNP was noted to be a more accurate prognostic marker than hsCRP (area under the curve of 0.74 compared with 0.67 for hsCRP, P < .05)., Conclusion: Patients with CHF and LVSD have increased serum concentrations of hsCRP that are related to functional limitation and prognosis but not to the severity of LV ejection fraction.

- Abstract
Background: Statins (3-hydroxy-3-methyl-glutaryl coenzyme A reductase inhibitors) are known to reduce mortality and cardiac events in patients with coronary artery disease who have not progressed to left ventricular systolic dysfunction (LVSD) and/or heart failure (HF). This study investigated the effect of changes in statin therapy and cholesterol level on mortality in patients with LVSD., Methods: Data from consecutive patients with LVSD enrolled in a single local hospital HF management program were analyzed. Patients were grouped according to changes in statin treatment within 4 months after their initial visit: groups NS (no statin), IS (initiation of statin), CS (continuation of statin), and SS (statin stopped)., Results: Nine hundred patients were followed for a median of 36 (28-43) months (range, 16-66 months). The 2-year mortality was 16.7%. Groups IS and CS had lower 2-year mortality than groups NS and SS (11.0% and 11.9% vs 22.0% and 34.8%, respectively; P < .001). This was independent of age, sex, severity of LVSD, HF medications, New York Heart Association functional class, and baseline cholesterol. The effect was mainly observed in patients with coronary artery disease. In 734 patients who had completed 1-year follow-up on stable HF treatment, neither baseline cholesterol nor change over 1 year predicted outcome., Conclusion: Initiation and maintenance of treatment with statins is associated with better survival in patients with LVSD. This could not be explained by other measured variables.
