A Systematic Review and Meta-Analysis of Prevalence, Characteristics, and Impact of Mitral Annular Calcification on Outcomes After Transcatheter Aortic Valve Implantation

There is a paucity of data on the prognostic impact of mitral annular calcification (MAC) in patients who underwent transcatheter aortic valve implantation (TAVI) with conflicting results being reported by the studies that are published. Therefore, we performed a meta-analysis to assess the short-term and long-term outcomes of MAC in patients after TAVI. Of 25,407 studies identified after the initial database search, 4 observational studies comprising 2,620 patients (2,030 patients in the nonsevere MAC arm and 590 patients in the severe MAC arm) were included in the final analysis. Compared with patients with nonsevere MAC, the severe MAC group was associated with significantly higher incidences of overall bleeding (0.75 [0.57 to 0.98], p = 0.03, I² = 0%) at 30 days. However, no significant difference was observed between the 2 groups for the rest of the 30-day outcomes: all-cause mortality (0.79 [0.42 to 1.48], p = 0.46, I² = 9%), myocardial infarction (1.62 [0.37 to 7.04], p = 0.52, I² = 0%), cerebrovascular accident or stroke (1.22 [0.53 to 2.83], p = 0.64, I² = 0%), acute kidney injury (1.48 [0.64 to 3.42], p = 0.35, I² = 0%), and pacemaker implantation (0.70 [0.39 to 1.25], p = 0.23, I² = 68%). Similarly, follow-up outcomes also showed no significant difference between the 2 groups: all-cause mortality (0.69 [0.46 to 1.03], p = 0.07, I² = 44%), cardiovascular mortality (0.52 [0.24 to 1.13], p = 0.10, I² = 70%) and stroke (0.83 [0.41 to 1.69], p = 0.61, I² = 22%). The sensitivity analysis, however, demonstrated significant results for all-cause mortality (0.57 [0.39 to 0.84], p = 0.005, I² = 7%) by removing the study by Okuno et al⁵ and cardiovascular mortality (0.41 [0.21 to 0.82], p = 0.01, I² = 66%) by removing the study by Lak et al.⁷ In conclusion, our meta-analysis corroborates the notion that isolated MAC is not an independent predictor of long-term mortality after TAVI and determines severe MAC to be a predictor of mortality at follow-up because of the higher incidence of mitral valve dysfunction associated with it.

In-hospital mortality of COVID-19 patients hospitalized with ST-segment elevation myocardial infarction: A meta-analysis

Introduction

Coronavirus Disease 2019 (COVID-19) has been associated with an increased risk of adverse cardiovascular events including arteriovenous thrombosis, myocarditis and acute myocardial injury. Relevant literature to date has reported widely varying estimates of mortality, ranging from approximately 2 to 11 times higher odds of mortality in COVID-19-positive STEMI (ST-segment elevation myocardial infarction) patients. Hence, we conducted this meta-analysis to resolve these inconsistencies and assess the impact of COVID-19 infection on mortality and other clinical outcomes in patients presenting with STEMI.

Methods

This meta-analysis was registered in PROSPERO (CRD42021297458) and performed according to the Cochrane Handbook for Systematic Reviews of Interventions. PubMed and Embase were searched from inception to November 2021 (updated on April 2022) using a search strategy consisting of terms relating to COVID-19, STEMI, and mortality.

Results

We identified 435 studies through our initial search. After screening according to our eligibility criteria, a total of 11 studies were included. Compared with the non-COVID-19 STEMI patients, the in-hospital mortality rate was higher in COVID-19-positive STEMI patients. Similarly, the risk of cardiogenic shock was higher in the COVID-19-positive patients. Length of hospital stay was longer in STEMI patients with COVID-19.

Conclusions

Our study highlights the necessity for early evaluation of COVID-19 status in all STEMI patients followed by risk stratification, prompt reperfusion and more aggressive management of COVID-19-positive patients. Further research is needed to elucidate the mechanisms behind poorer prognosis in such patients.

Impact of elevated left ventricular filling pressure on long-term outcomes after transcatheter aortic valve replacement

BACKGROUND

Increase in left ventricular filling pressure (FP) and diastolic dysfunction are established consequences of progressive aortic stenosis (AS). However, the impact of elevated FP as detected by pretranscatheter aortic valve replacement (TAVR) echocardiogram on long-term outcomes after TAVR remains unclear.

OBJECTIVE

To understand the impact of elevated FP in patients with severe AS who undergo TAVR.

METHODS

This was a retrospective study of all patients who underwent TAVR between 1 January 2014 and 31 December 2017. The presence of elevated FP was determined in accordance with the latest guidelines using the last available comprehensive echocardiogram prior to TAVR.

RESULTS

Of 983 patients who were included in our study, 422 patients (43%) were found to have elevated FP and 561 patients (57%) had normal FP prior to TAVR. Patients with elevated FP had a mean age of 81.2±8.6 years and were more likely to be males (62%), diabetic (41% vs 35%, p=0.046), and have a higher prevalence of atrial fibrillation (Afib) (53% vs 39%, p<0.001). The 5-year all-cause mortality after TAVR was significantly higher in patients with elevated FP when compared with patients with normal FP (32% vs 24%, p=0.006). The presence of elevated FP, history of Afib and prior PCI emerged as independent predictors of long-term mortality after TAVR.

CONCLUSION

Elevated FP is associated with increased mortality in patients with severe AS undergoing TAVR. Assessment of FP should be incorporated into the risk assessment of AS patients to identify those who may benefit from early intervention.

Meta-Analysis Comparing Distal Radial Versus Traditional Radial Percutaneous Coronary Intervention or Angiography

Data comparing outcomes of distal radial (DR) and traditional radial (TR) access of coronary angiography and percutaneous coronary intervention (PCI) are limited. Online databases including Medline and Cochrane Central databases were explored to identify studies that compared DR and TR access for PCI. The primary outcome was the rate of radial artery occlusion (RAO) and access failure. Secondary outcomes included access site hematoma, access site bleeding, access site pain, radial artery spasm, radial artery dissection, and crossover. Unadjusted odds ratios (ORs) with a random-effect model, 95% confidence interval (CI), and p <0.05 were used for statistical significance. Metaregression was performed for 16 studies with 9,973 (DR 4,750 and TR 5,523) patients were included. Compared with TR, DR was associated with lower risk of RAO (OR 0.51, 95% CI 0.29 to 0.90, I² = 42.6%, p = 0.02). RAO was lower in DR undergoing coronary angiography rather than PCI. Access failure rate (OR 1.77, 95% CI 0.69 to 4.55, I² 87.36%, p = 0.24), access site hematoma (OR 1.11, 95% CI 0.68 to 1.83, I² 0%, p = 0.68), access site pain (OR 2.22, 95% CI 0.28 to 17.38, I² 0%, p = 0.45), access site bleeding (OR 1.11, 95% CI 0.16 to 7.62, I² 85.11%, p = 0.91), radial artery spasm (OR 0.79, 95% CI 0.49 to 1.29, I² 0%, p = 0.35), radial artery dissection (OR 1.63, 95% CI 0.46 to 5.84, I² 0%, p = 0.45), and crossover (OR 1.54, 95% CI 0.64 to 3.70, I² 25.48%, p = 0.33) did not show any significant difference. DR was associated with lower incidence RAO when compared with TR, whereas other procedural-related complications were similar.

Efficacy and Safety of Catheter Ablation vs Antiarrhythmic Drugs as Initial Therapy for Management of Symptomatic Paroxysmal Atrial Fibrillation: A Meta-Analysis

BACKGROUND

Catheter ablation is an effective treatment for atrial fibrillation (AF), primarily performed in patients who fail antiarrhythmic drugs. Whether early catheter ablation, as first-line therapy, is associated with improved clinical outcomes remains unclear.

METHODS

Electronic databases (PubMed, Scopus, Embase) were searched until March 28th, 2021. Randomized controlled trials (RCTs) compared catheter ablation vs antiarrhythmic drug therapy as first-line therapy were included. The primary outcome of interest was the first documented recurrence of any atrial tachyarrhythmia (symptomatic or asymptomatic; AF, atrial flutter, and atrial tachycardia). Secondary outcomes included symptomatic atrial tachyarrhythmia (AF, atrial flutter, and atrial tachycardia) and serious adverse events. Unadjusted risk ratios (RR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance considered if the confidence interval (CI) excludes one and p < 0.05.

RESULTS

A total of six RCTs with 1212 patients (Ablation n = 609; Antiarrhythmic n = 603) were included. Follow- up period ranged from 1-2 years. Patients who underwent ablation were less likely to experience any recurrent atrial tachyarrhythmia when compared to patients receiving antiarrhythmic drugs (RR 0.63; 95% CI 0.55-0.73; p < 0.00001). Symptomatic atrial tachyarrhythmia was also lower in the ablation arm (RR 0.53; 95% CI 0.32-0.87; p = 0.01). No statistically significant differences were noted for overall any type of adverse events (RR 0.93; 95% CI 0.68-1.27; p = 0.64) and cardiovascular adverse events (RR 0.90; 95% CI 0.56-1.44; p = 0.65) respectively.

CONCLUSIONS

Catheter ablation, as first-line therapy, was associated with a significantly lower rate of tachyarrhythmia recurrence compared to conventional antiarrhythmic drugs, with a similar adverse effect risk profile. These findings support a catheter ablation strategy as first-line therapy among patients with symptomatic paroxysmal atrial fibrillation.

Association of pepper intake with all-cause and specific cause mortality - A systematic review and meta-analysis

OBJECTIVE

To conduct a comprehensive systematic review and meta-analysis to compare mortality and other clinical outcomes associated with chili pepper (CP) consumption versus no/rare consumption of CP.

METHODS

A comprehensive search was performed using Ovid, Cochrane, Medline, EMBASE, and Scopus from inception till January 16, 2020. Observational studies and randomized controlled trials were included, while pediatric/animal studies, letters/case reports, reviews, abstracts, and book chapters were excluded. All-cause mortality was studied as the primary outcome. Cardiovascular mortality, cancer-related deaths and cerebrovascular accidents were studied as secondary outcomes.

RESULTS

From 4729 studies, four studies met the inclusion criteria. Random effects pooled analysis showed that all-cause mortality among CP consumers was lower, compared to rare/non-consumers, with a hazard ratio (HR) of 0.87 [95% CI: 0.85-0.90; p<0.0001; I 2=1%]. HR for cardiovascular mortality was 0.83 [95% CI: 0.74-0.95; p = 0.005, I 2=66%] and for cancer-related mortality as 0.92 [95% CI: 0.87-0.97; p = 0.001; I 2=0%]. However, the HR for CVA was 0.78 [95% CI: 0.56-1.09; p = 0.26; I2 =60%]. The mode and amount of CP consumption varied across the studies, and data were insufficient to design an optimal strategy guiding its intake.

CONCLUSION

Regular CP consumption was associated with significantly lower all-cause, cardiovascular, and cancer-related mortalities. However, based on current literature, it is difficult to derive a standardized approach to guide the optimal mode and amount of CP consumption. This warrants well-designed prospective studies to further investigate the potential health benefits of CP consumption.

Global, regional, and national sex differences in the global burden of tuberculosis by HIV status, 1990-2019: results from the Global Burden of Disease Study 2019

BACKGROUND

Tuberculosis is a major contributor to the global burden of disease, causing more than a million deaths annually. Given an emphasis on equity in access to diagnosis and treatment of tuberculosis in global health targets, evaluations of differences in tuberculosis burden by sex are crucial. We aimed to assess the levels and trends of the global burden of tuberculosis, with an emphasis on investigating differences in sex by HIV status for 204 countries and territories from 1990 to 2019.

METHODS

We used a Bayesian hierarchical Cause of Death Ensemble model (CODEm) platform to analyse 21 505 site-years of vital registration data, 705 site-years of verbal autopsy data, 825 site-years of sample-based vital registration data, and 680 site-years of mortality surveillance data to estimate mortality due to tuberculosis among HIV-negative individuals. We used a population attributable fraction approach to estimate mortality related to HIV and tuberculosis coinfection. A compartmental meta-regression tool (DisMod-MR 2.1) was then used to synthesise all available data sources, including prevalence surveys, annual case notifications, population-based tuberculin surveys, and tuberculosis cause-specific mortality, to produce estimates of incidence, prevalence, and mortality that were internally consistent. We further estimated the fraction of tuberculosis mortality that is attributable to independent effects of risk factors, including smoking, alcohol use, and diabetes, for HIV-negative individuals. For individuals with HIV and tuberculosis coinfection, we assessed mortality attributable to HIV risk factors including unsafe sex, intimate partner violence (only estimated among females), and injection drug use. We present 95% uncertainty intervals for all estimates.

FINDINGS

Globally, in 2019, among HIV-negative individuals, there were 1·18 million (95% uncertainty interval 1·08-1·29) deaths due to tuberculosis and 8·50 million (7·45-9·73) incident cases of tuberculosis. Among HIV-positive individuals, there were 217 000 (153 000-279 000) deaths due to tuberculosis and 1·15 million (1·01-1·32) incident cases in 2019. More deaths and incident cases occurred in males than in females among HIV-negative individuals globally in 2019, with 342 000 (234 000-425 000) more deaths and 1·01 million (0·82-1·23) more incident cases in males than in females. Among HIV-positive individuals, 6250 (1820-11 400) more deaths and 81 100 (63 300-100 000) more incident cases occurred among females than among males in 2019. Age-standardised mortality rates among HIV-negative males were more than two times greater in 105 countries and age-standardised incidence rates were more than 1·5 times greater in 74 countries than among HIV-negative females in 2019. The fraction of global tuberculosis deaths among HIV-negative individuals attributable to alcohol use, smoking, and diabetes was 4·27 (3·69-5·02), 6·17 (5·48-7·02), and 1·17 (1·07-1·28) times higher, respectively, among males than among females in 2019. Among individuals with HIV and tuberculosis coinfection, the fraction of mortality attributable to injection drug use was 2·23 (2·03-2·44) times greater among males than females, whereas the fraction due to unsafe sex was 1·06 (1·05-1·08) times greater among females than males.

INTERPRETATION

As countries refine national tuberculosis programmes and strategies to end the tuberculosis epidemic, the excess burden experienced by males is important. Interventions are needed to actively communicate, especially to men, the importance of early diagnosis and treatment. These interventions should occur in parallel with efforts to minimise excess HIV burden among women in the highest HIV burden countries that are contributing to excess HIV and tuberculosis coinfection burden for females. Placing a focus on tuberculosis burden among HIV-negative males and HIV and tuberculosis coinfection among females might help to diminish the overall burden of tuberculosis. This strategy will be crucial in reaching both equity and burden targets outlined by global health milestones.

Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019

BACKGROUND

Given the projected trends in population ageing and population growth, the number of people with dementia is expected to increase. In addition, strong evidence has emerged supporting the importance of potentially modifiable risk factors for dementia. Characterising the distribution and magnitude of anticipated growth is crucial for public health planning and resource prioritisation. This study aimed to improve on previous forecasts of dementia prevalence by producing country-level estimates and incorporating information on selected risk factors.

METHODS

We forecasted the prevalence of dementia attributable to the three dementia risk factors included in the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 (high body-mass index, high fasting plasma glucose, and smoking) from 2019 to 2050, using relative risks and forecasted risk factor prevalence to predict GBD risk-attributable prevalence in 2050 globally and by world region and country. Using linear regression models with education included as an additional predictor, we then forecasted the prevalence of dementia not attributable to GBD risks. To assess the relative contribution of future trends in GBD risk factors, education, population growth, and population ageing, we did a decomposition analysis.

FINDINGS

We estimated that the number of people with dementia would increase from 57·4 (95% uncertainty interval 50·4-65·1) million cases globally in 2019 to 152·8 (130·8-175·9) million cases in 2050. Despite large increases in the projected number of people living with dementia, age-standardised both-sex prevalence remained stable between 2019 and 2050 (global percentage change of 0·1% [-7·5 to 10·8]). We estimated that there were more women with dementia than men with dementia globally in 2019 (female-to-male ratio of 1·69 [1·64-1·73]), and we expect this pattern to continue to 2050 (female-to-male ratio of 1·67 [1·52-1·85]). There was geographical heterogeneity in the projected increases across countries and regions, with the smallest percentage changes in the number of projected dementia cases in high-income Asia Pacific (53% [41-67]) and western Europe (74% [58-90]), and the largest in north Africa and the Middle East (367% [329-403]) and eastern sub-Saharan Africa (357% [323-395]). Projected increases in cases could largely be attributed to population growth and population ageing, although their relative importance varied by world region, with population growth contributing most to the increases in sub-Saharan Africa and population ageing contributing most to the increases in east Asia.

INTERPRETATION

Growth in the number of individuals living with dementia underscores the need for public health planning efforts and policy to address the needs of this group. Country-level estimates can be used to inform national planning efforts and decisions. Multifaceted approaches, including scaling up interventions to address modifiable risk factors and investing in research on biological mechanisms, will be key in addressing the expected increases in the number of individuals affected by dementia.

Artificial intelligence in the diagnosis and detection of heart failure: the past, present, and future

Artificial Intelligence (AI) performs human intelligence-dependant tasks using tools such as Machine Learning, and its subtype Deep Learning. AI has incorporated itself in the field of cardiovascular medicine, and increasingly employed to revolutionize diagnosis, treatment, risk prediction, clinical care, and drug discovery. Heart failure has a high prevalence, and mortality rate following hospitalization being 10.4% at 30-days, 22% at 1-year, and 42.3% at 5-years. Early detection of heart failure is of vital importance in shaping the medical, and surgical interventions specific to HF patients. This has been accomplished with the advent of Neural Network (NN) model, the accuracy of which has proven to be 85%. AI can be of tremendous help in analyzing raw image data from cardiac imaging techniques (such as echocardiography, computed tomography, cardiac MRI amongst others) and electrocardiogram recordings through incorporation of an algorithm. The use of decision trees by Rough Sets (RS), and logistic regression (LR) methods utilized to construct decision-making model to diagnose congestive heart failure, and role of AI in early detection of future mortality and destabilization episodes has played a vital role in optimizing cardiovascular disease outcomes. The review highlights the major achievements of AI in recent years that has radically changed nearly all areas of HF prevention, diagnosis, and management.

Outcomes After Transfemoral Transcatheter Aortic Valve Implantation With a SAPIEN 3 Valve in Patients With Cirrhosis of the Liver (a Tertiary Care Center Experience)

Little is known about the utility of transcatheter aortic valve implantation (TAVI) in patients with cirrhosis of the liver, and their outcomes have not been studied extensively in literature. We performed a retrospective analysis of patients with severe symptomatic aortic stenosis (AS) who underwent transfemoral TAVI with a SAPIEN 3 valve at our institution between April 2015 and December 2018. We identified 32 consecutive patients with evidence of cirrhosis of the liver on imaging (including ultrasound and/or computed tomography) and patients with severe symptomatic AS who underwent transfemoral TAVI with a SAPIEN 3 valve. Among 1,028 patients, 32 had cirrhosis of the liver and 996 constituted the control group without cirrhosis. Mean age in the cirrhosis group was 74.5 years compared with 81.2 years in the control group. Baseline variables were comparable between the groups. Compared with the noncirrhotic group, patients with cirrhosis had a similar 1-year mortality (12% vs 12%, p = 1), a lower 30-day new pacemaker after TAVI rate (6% vs 9%, p = 0.85), a higher 30-day and 1-year readmission rate for heart failure (11% vs 1% and 12% vs 5%, p = 0.12, respectively), and a similar 1-year major adverse cardiac and cerebrovascular event rate (15% vs 14%, p = 0.98). In conclusion, patients with severe AS with concomitant liver cirrhosis who underwent TAVI demonstrated comparable outcomes to their noncirrhotic counterparts.

Refractory Recurrent Pericarditis After Pericardiectomy in a Young Woman

Pericardiectomy is the recommended treatment for patients with recurrent pericarditis and refractory symptoms despite optimal anti-inflammatory therapy. We present a case of a 40-year-old woman who underwent total pericardiectomy after multiple episodes of pericarditis that was refractory to optimal guideline-derived medical therapy, including anti-inflammatory and biologic agents, who continued to have relapsing symptoms even after pericardiectomy. (Level of Difficulty: Intermediate.)

Global, regional, and national burden of stroke and its risk factors, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Regularly updated data on stroke and its pathological types, including data on their incidence, prevalence, mortality, disability, risk factors, and epidemiological trends, are important for evidence-based stroke care planning and resource allocation. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) aims to provide a standardised and comprehensive measurement of these metrics at global, regional, and national levels.

METHODS

We applied GBD 2019 analytical tools to calculate stroke incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and the population attributable fraction (PAF) of DALYs (with corresponding 95% uncertainty intervals [UIs]) associated with 19 risk factors, for 204 countries and territories from 1990 to 2019. These estimates were provided for ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage, and all strokes combined, and stratified by sex, age group, and World Bank country income level.

FINDINGS

In 2019, there were 12·2 million (95% UI 11·0-13·6) incident cases of stroke, 101 million (93·2-111) prevalent cases of stroke, 143 million (133-153) DALYs due to stroke, and 6·55 million (6·00-7·02) deaths from stroke. Globally, stroke remained the second-leading cause of death (11·6% [10·8-12·2] of total deaths) and the third-leading cause of death and disability combined (5·7% [5·1-6·2] of total DALYs) in 2019. From 1990 to 2019, the absolute number of incident strokes increased by 70·0% (67·0-73·0), prevalent strokes increased by 85·0% (83·0-88·0), deaths from stroke increased by 43·0% (31·0-55·0), and DALYs due to stroke increased by 32·0% (22·0-42·0). During the same period, age-standardised rates of stroke incidence decreased by 17·0% (15·0-18·0), mortality decreased by 36·0% (31·0-42·0), prevalence decreased by 6·0% (5·0-7·0), and DALYs decreased by 36·0% (31·0-42·0). However, among people younger than 70 years, prevalence rates increased by 22·0% (21·0-24·0) and incidence rates increased by 15·0% (12·0-18·0). In 2019, the age-standardised stroke-related mortality rate was 3·6 (3·5-3·8) times higher in the World Bank low-income group than in the World Bank high-income group, and the age-standardised stroke-related DALY rate was 3·7 (3·5-3·9) times higher in the low-income group than the high-income group. Ischaemic stroke constituted 62·4% of all incident strokes in 2019 (7·63 million [6·57-8·96]), while intracerebral haemorrhage constituted 27·9% (3·41 million [2·97-3·91]) and subarachnoid haemorrhage constituted 9·7% (1·18 million [1·01-1·39]). In 2019, the five leading risk factors for stroke were high systolic blood pressure (contributing to 79·6 million [67·7-90·8] DALYs or 55·5% [48·2-62·0] of total stroke DALYs), high body-mass index (34·9 million [22·3-48·6] DALYs or 24·3% [15·7-33·2]), high fasting plasma glucose (28·9 million [19·8-41·5] DALYs or 20·2% [13·8-29·1]), ambient particulate matter pollution (28·7 million [23·4-33·4] DALYs or 20·1% [16·6-23·0]), and smoking (25·3 million [22·6-28·2] DALYs or 17·6% [16·4-19·0]).

INTERPRETATION

The annual number of strokes and deaths due to stroke increased substantially from 1990 to 2019, despite substantial reductions in age-standardised rates, particularly among people older than 70 years. The highest age-standardised stroke-related mortality and DALY rates were in the World Bank low-income group. The fastest-growing risk factor for stroke between 1990 and 2019 was high body-mass index. Without urgent implementation of effective primary prevention strategies, the stroke burden will probably continue to grow across the world, particularly in low-income countries.

Cardiac manifestations of the coronavirus disease-19: a review of pathogenesis, clinical manifestations, diagnosis, and treatment

The coronavirus disease-19 (COVID-19), first appearing in Wuhan, China, and later declared as a pandemic, has caused serious morbidity and mortality worldwide. Severe cases usually present with acute respiratory distress syndrome (ARDS), pneumonia, acute kidney injury (AKI), liver damage, or septic shock. However, with recent advances in severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) research, the virus´s effect on cardiac tissues has become evident. Reportedly, an increased number of COVID-19 patients manifested serious cardiac complications such as heart failure, increased troponin, and N-terminal pro-B-type natriuretic peptide levels (NT-proBNP), cardiomyopathies, and myocarditis. These cardiac complications initially present as chest tightness, chest pain, and heart palpitations. Diagnostic investigations such as telemetry, electrocardiogram (ECG), cardiac biomarkers (troponin, NT-proBNP), and inflammatory markers (D-dimer, fibrinogen, PT, PTT), must be performed according to the patient´s condition. The best available options for treatment are the provision of supportive care, anti-viral therapy, hemodynamic monitoring, IL-6 blockers, statins, thrombolytic, and anti-hypertensive drugs. Cardiovascular disease (CVD) healthcare workers should be well-informed about the evolving research regarding COVID-19 and approach as a multi-disciplinary team to devise effective strategies for challenging situations to reduce cardiac complications.

Exploring the impact of the COVID-19 pandemic on provision of cardiology services: a scoping review

The coronavirus disease-19 (COVID-19) pandemic has forced hospitals to prioritize COVID-19 patients, restrict resources, and cancel all non-urgent elective cardiac procedures. Clinical visits have only been facilitated for emergency purposes. Fewer patients have been admitted to the hospital for both ST-segment elevation myocardial infarctions (STEMI) and non-ST segment elevation myocardial infarctions (NSTEMI) and a profound decrease in heart failure services has been reported. A similar reduction in the patient presentation is seen for ischemic heart disease, decompensated heart failure, and endocarditis. Cardiovascular services, including catheterization, primary percutaneous coronary intervention (PPCI), cardiac investigations such as electrocardiograms (ECGs), exercise tolerance test (ETT), dobutamine stress test, computed tomography (CT) angiography, transesophageal echocardiography (TOE) have been reported to have declined and performed on a priority basis. The long-term implications of this decline have been discussed with major concerns of severe cardiac complications and vulnerabilities in cardiac patients. The pandemic has also had psychological impacts on patients causing them to avoid seeking medical help. This review discusses the effects of the COVID-19 pandemic on the provision of various cardiology services and aims to provide strategies to restore cardiovascular services including structural changes in the hospital to make up for the reduced staff personnel, the use of personal protective equipment in healthcare workers, and provides alternatives for high-risk cardiac imaging, cardiac interventions, and procedures. Implementation of the triage system, risk assessment scores, and telemedicine services in patients and their adaptation to the cardiovascular department have been discussed.

Cardiac papillary fibroelastoma originating from the coumadin ridge and review of literature

Papillary fibroelastomas represent the second most common benign cardiac tumour, secondary only to cardiac myxoma. A majority of patients are asymptomatic on presentation. The most common clinical manifestations include stroke, transient ischaemic attack, myocardial infarction and angina. Echocardiography remains the primary imaging modality for identification of these tumours. The majority of papillary fibroelastomas arise from the valves. Simple surgical excision is the mainstay of treatment, carrying an excellent prognosis. We present an unusual case of cardiac papillary fibroelastoma originating from the coumadin ridge (CR) in a 70-year-old woman. The patient exhibited increasing paroxysms of her atrial fibrillation and was pursuing a MAZE procedure. Preoperatively, a transesophageal echocardiogram revealed a 0.7×1 cm intracardiac mass that had echocardiographic appearance of a fibroelastoma. Surgical resection and MAZE procedures were performed. The gross specimen and histopathology findings were consistent with papillary fibroelastoma. This case reports the seventh documented case of fibroelastoma originating from the CR.
