Rare Variant of Meigs Syndrome Associated With Pericardial Effusion.

Meigs syndrome is an uncommon entity associated with benign ovarian tumor, pleural effusion, and ascites. Its association with pericardial effusion is extremely rare. We report a case of Meigs syndrome associated with recurrent pericardial effusion that resolved after surgical resection of the ovarian tumor. (Level of Difficulty: Beginner.).

Cardiac macrophage density in Covid-19 infection: relationship to myocyte necrosis and acute lung injury.

SARS-Cov-2 infection is not limited to the respiratory tract and can involve other organs including the heart, blood vessels, kidneys, liver, gastrointestinal tract, placenta, and skin. Covid-19 patients with cardiac involvement usually have higher morbidity and mortality compared to those without cardiac involvement. The frequency and the specificity of the myocardial pathological changes in patients who die after documented infection with SARS-Cov-2 is uncertain. Macrophages can be found in the normal heart (interstitium, around the endothelial cells and in the epicardial adipose tissue), and they are considered part of the major immune cell population in the heart. In this case-control autopsy study, we compare the gross and microscopic cardiac findings, and the available clinical characteristics between a group of 10 Covid-19 decedents and a control group of 20 patients who died with non-SARS-Cov-2 severe bronchopneumonia and/or diffuse alveolar damage. The objectives of this semi-quantitative study are to study single myocyte necrosis and its relation to the strain on the heart caused by lung injury as a causative mechanism, and to study the density of myocardial and epicardial macrophages in Covid-19 hearts in comparison to the control group, and in Covid-19 hearts with single myocyte necrosis in comparison to Covid-19 hearts without single myocyte necrosis. Lymphocytic myocarditis was not identified in any of the hearts from the Covid-19 or the control group. Single myocyte necrosis is more frequent in the Covid-19 group compared to the control group, suggesting that it is unrelated to the strain on the heart caused by underlying lung injury. The density of the macrophages in the epicardium and myocardium in the hearts of the Covid-19 group is higher compared to those in the control group. The density of epicardial macrophages is higher in the Covid-19 hearts with single myocyte necrosis than in those without. These observations contribute to our increasing appreciation of the role of macrophages in the pathophysiologic response to infection by SARS-CoV-2.

Transfemoral aortic valve replacement in a nonagenarian with aortic stenosis and cardiac amyloidosis: case report.

BACKGROUND: Cardiac amyloidosis (CA) is diagnosed with increasing frequency in the elderly population with severe aortic stenosis (AS), especially with the low-flow, low- gradient phenotype. Prognosis is poor with no treatment. CASE PRESENTATION: The patient is a 94-year-old active male who presented with a stroke that fully resolved. He was found to have low-flow, low-gradient severe AS, along with concomitant CA. Gradients across the aortic valve worsened with the dobutamine challenge test. He underwent successful transfemoral aortic valve replacement (TAVR) and did well postoperatively, where he remained in the hospital for only one day. Treatment of his CA with Tafamidis was recommended; however, the patient declined due to its cost and personal preference. CONCLUSION: To our knowledge, we report on one of the oldest patients to undergo TAVR for low-flow, low-gradient AS with concurrent CA (AS-CA). It might be prudent to screen elderly patients with AS for CA, as prognosis is worse with medical management alone. TAVR has overall improved survival in patients with AS-CA and is considered the procedure of choice, as these patients are typically older and at higher risk for surgical intervention.

Pregnancy-Associated Myocardial Infarction: A Review of Current Practices and Guidelines.

PURPOSE OF REVIEW: Pregnancy-associated myocardial infarction is a principal cause of cardiovascular disease with a steadily rising incidence of 4.98 AMI events/100,000 deliveries over the last four decades in the USA. It is also linked with significant maternal and fetal morbidity and mortality, with maternal case fatality rate ranging from 5.1 to 37%. The management of acute myocardial infarction can be challenging in pregnant patients since treatment modalities and medication use are limited by their safety during pregnancy. RECENT FINDINGS: Limited guidelines exist regarding the management of pregnancy-associated myocardial infarction. Routinely used medications in myocardial infarction including angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), and statin therapy are contraindicated during pregnancy. Aspirin use is considered safe in pregnant women, but dual antiplatelet therapy and therapeutic anticoagulation can be associated with increased risk of maternal and fetal complications, and should only be used after a comprehensive benefit-to-risk assessment. The standard approach to revascularization requires additional caution in pregnant women. Percutaneous coronary intervention is generally considered safe but can be associated with high failure rates and poor outcomes depending on the etiology. Fibrinolytic therapy may have significant sequelae in pregnant patients, and hemodynamic management during surgery is complex and adds risk during pregnancy. Understanding the risks and benefits of the different treatment modalities available and their utility depending on the underlying etiology, encompassed with a multidisciplinary team approach, is vital to improve outcomes and minimize maternal and fetal complications.

Postoperative Myocardial Injury in Patients Classified as Low Risk Preoperatively Is Associated With a Particularly Increased Risk of Long-Term Mortality After Noncardiac Surgery.

Background Prior studies have shown an association between myocardial injury after noncardiac surgery (MINS) and all-cause mortality in patients following noncardiac surgery. However, the association between preoperative risk assessments, Revised Cardiac Risk Index and American College of Surgeons National Surgical Quality Improvement Program, and postoperative troponin elevations and long-term mortality is unknown. Methods and Results A retrospective chart review identified 548 patients who had a troponin I level drawn within 14 days of noncardiac surgery that required an overnight hospital stay. Patients aged 40 to 80 years with at least 2 cardiovascular risk factors were included, while those with trauma, pulmonary embolism, and neurosurgery were excluded. Kaplan-Meier survival and odds ratio (OR) with sensitivity/specificity analysis were performed to assess the association between preoperative risk and postoperative troponin elevation and all-cause mortality at 1 year. Overall, 69%/31% were classified as low-risk/high-risk per the Revised Cardiac Risk Index and 66%/34% per American College of Surgeons National Surgical Quality Improvement Program. Comparing the low-risk versus high-risk groups, preoperative risk assessment was not associated with either postoperative troponin elevation or 1-year mortality. MINS portended a 1-year mortality of OR, 3.9 (95% CI, 2.44-6.33) in the total population. Patients classified as low risk preoperatively with MINS had the highest risk of 1-year mortality (OR, 9.6; 95% CI, 4.27-24.38), with a low prevalence of statin use. Conclusions Current preoperative risk stratification tools do not prognosticate the risk of postoperative troponin elevation and all-cause mortality at 1 year. Interestingly, patients classified as low risk preoperatively with MINS had a markedly higher 1-year mortality risk compared with the general population, and most of them are not taking a statin. Our results suggest that evaluating preoperatively low-risk patients for MINS presents an opportunity for prognostication, risk reclassification, and initiating therapies such as statins to mitigate long-term risk.

Canakinumab: Promises and Future in Cardiometabolic Diseases and Malignancy.

Inflammation has proven in multiple studies to be responsible for the progression of cardiometabolic diseases and malignancies. The interleukin family has been critically associated with progression of atherosclerosis, insulin resistance, and various malignancies. Given the advent of pharmacologic interleukin-1 (IL-1) inhibition, this pathway can potentially be targeted to improve outcomes. In the recently concluded Canakinumab Anti-inflammatory Thrombosis Outcomes Study (CANTOS) trial, investigators looked at the potential role of IL-1 (especially IL-1ß) inhibition in halting the progression of atherosclerosis. In the subset analysis of the data from this trial, IL-1ß inhibition with canakinumab was found to have beneficial effects in other cardiometabolic diseases characterized by inflammation, like diabetes, stroke, and chronic kidney disease, and also in patients with lung cancer. In this article, we will try to review the current literature on the role of canakinumab in the treatment of cardiometabolic diseases and malignancies.
