RESUMEN
Severe mitral regurgitation (MR) is an important cause of acute heart failure and significant contributor to morbidity and mortality. Mechanical circulatory support (MCS) devices such as Impella are readily used to hemodynamically stabilize patients with cardiogenic shock (CS) secondary to this valvular pathology. Impella can also be combined with VA-ECMO to an "ECPELLA" configuration if further escalation of hemodynamic support is needed. We report a case of a 57-year-old female who presented with CS secondary to a perforated anterior mitral valve leaflet and non-ischemic cardiomyopathy that did not stabilize with initial choice of Impella 5.5. She required further escalation from axillary Impella 5.5 to the combined ECPELLA configuration, which allowed hemodynamic stabilization and ultimately a successful high-risk isolated mitral valve replacement. Despite adequate Impella flow, escalation to a combined MCS configuration, such as ECPELLA, may need to be considered upfront for acute valvular insufficiency in the setting of pre-existing cardiomyopathy.
RESUMEN
Landiolol is an ultra-short-acting, highly cardio-selective, ß-blocker, that is currently approved for clinical use in Japan and the European Union, for the treatment of tachyarrhythmias. Landiolol is highly cardio-selective with high ß1 selectivity and receptor affinity, resulting in a more potent chronotropic effect and less potent hypotensive effect compared with other ß-blockers such as esmolol and propranolol. Based on the recent randomized controlled trials, low-dose landiolol may have a beneficial role in the prevention and management of postoperative atrial fibrillation following noncardiac and cardiac surgeries, including on-pump and off-pump coronary artery bypass grafting and valve surgery. Additionally, landiolol may have potential utility for myocardial salvage and prevention of postpercutaneous coronary intervention myocardial infarction. Furthermore, the use of landiolol may also have a therapeutic effect for rate control of sepsis-related tachyarrhythmias. Positive results of recent randomized controlled trials should continue to inspire clinicians to conduct further, larger studies, to find new potential clinical applications for this novel drug.
RESUMEN
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant inherited condition defined by left ventricular wall thickness greater than 15 mm in the absence of other conditions that could explain that degree of hypertrophy. Obstructive HCM associated with left ventricular outflow tract obstruction is defined by an intraventricular systolic pressure gradient greater than or equal to 30 mm Hg. Over the past couple of decades, there has been an expansion of both invasive and pharmacotherapeutic options for patients with HCM, with recent guidelines calling for a melody of invasive and non-invasive treatment strategies. There are several invasive therapies including proven therapies such as alcohol septal ablation and septal myectomy. Novel invasive therapies such as MitraClip, radiofrequency septal ablation and SESAME procedure have more recently been promoted. Pharmacological therapy has also dramatically evolved and includes conventional medications such as beta-blockers, calcium channel blockers, and disopyramide. Mavacamten, a novel cardiac myosin inhibitor, may significantly change management. Other myosin inhibitors and modulators are also being developed and tested in large clinical trials. Given significant phenotypical variability in patients with HCM, clinical management can be challenging, and often requires an individualized approach with a combination of invasive and non-invasive options.

Background: The high documentation demands and limited time in direct patient care in the first year of internal medicine residency represent concerns for burnout and low job satisfaction in this important year of training. Objective: To assess the effect of scribes on the time PGY-1 residents spent on various work tasks. Methods: Participants were 24 PGY-1 internal medicine residents on two inpatient medicine teams at one site for 6 months (September 2019-February 2020). Residents were assigned a scribe during the first or second 2 weeks of a 4-week rotation and had no scribe for the other 2 weeks. Time study observers documented resident work activities. Residents ranked the meaningfulness of work activities via survey at the end of each 2-week period. Results: Of 24 residents, 18 (75%) completed the survey at both time points. Residents ranked patient care as the most meaningful and EHR work as the least meaningful work activity. EHR work claimed the largest percentage of time, with or without a scribe (mean, 33.2% and 39%, respectively). With a scribe, residents spent significantly less time (-5.8%, P < 0.0001) in EHR work and significantly more time (1.3%, P = 0.0267) in direct patient care and coordinating patient care (3.0%, P < 0.0001). Conclusions: The presence of a scribe with PGY-1 internal medicine residents on inpatient teams resulted in a significantly greater percentage of total work time spent in work they considered most meaningful and a significantly lower percentage of total work time in work they considered least meaningful.
RESUMEN
In the setting of an acute pulmonary embolism (PE), there is often an assumed association between a saddle PE (SPE) and increased clinical severity. We aimed to determine the magnitude of SPE proximal pulmonary artery (PA) flow obstruction and its impact on right ventricular (RV) function in the setting of acute PE in a single-center series. From 2005 to 2022, patients with acute PE presenting with acute RV dysfunction requiring intervention were classified as SPE and non-SPE based on presenting computed tomography (CT) scans. SPE flow obstruction was determined by the ratio of the orthogonal cross-sectional surface area measurements of clot and native PA at the location of maximum clot burden in the right PA and left PA. Presenting RV function based on clinical and imaging parameters (CT and transthoracic echocardiography) were compared between SPE and non-SPE cohorts. A total of 174 patients were identified (SPE 92 [52.9%] and non-SPE 82 [47.1%]). Demographics and co-morbidities were similar. In patients with SPE, there was a mean 25.9% total flow obstruction (right PA 26.9% and left PA 25.5%). Non-SPE had greater clinical RV dysfunction on presentation as reflected by more high-risk PE (43.9% vs 26.1%, p = 0.01), need for venoarterial extracorporeal membrane oxygenation (21.9% vs 10.9%, p = 0.05), and more preoperative cardiopulmonary resuscitation (16.7% vs 7.8%, p = 0.08). RV:left ventricular ratio (CT and transthoracic echocardiography) and RV fractional area change were statistically similar between groups. In-hospital mortality was statistically similar between cohorts (4.9% non-SPE vs 2.1% SPE, p = 0.32). In conclusion, in a single-center series of patients with acute PE with RV dysfunction, SPE did not cause proximal flow-limiting obstruction. Non-SPE was associated with more clinical RV dysfunction than SPE. Thus, it should not be assumed that a non-SPE is a marker of patient stability.

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is one of the most common genetic causes of heart disease. Since the initial description of HCM, there have been minimal strides in management options. Obstructive HCM constitutes a larger subset of patients with increased left ventricular outflow tract gradients causing symptoms. Septal reduction therapy (SRT) has been successful, but it is not the answer for all patients and is not disease modifying. AREAS COVERED: Current guideline recommendations include beta-blockers, calcium channel blockers, or disopyramides for medical management, but there lacks evidence of much benefit with these drugs. In recent years, there has been the emergence of cardiac myosin inhibitors (CMI) which have demonstrated positive results in patients with both obstructive and non-obstructive HCM. In addition to CMIs, other drugs have been investigated as we have learned more about HCM's pathological mechanisms. Drugs targeting sodium channels and myocardial energetics, as well as repurposed drugs that have demonstrated positive remodeling are being investigated as potential therapeutic targets. Gene therapy is being explored with vast potential for the treatment of HCM. EXPERT OPINION: The armamentarium of therapeutic options for HCM is continuously increasing with the emergence of CMIs as mainstays of treatment. The future of HCM treatment is promising.

Yoga has been increasingly popular yet has shown inconsistent benefits on cardiovascular disease (CVD) risk factors. We aimed to systematically analyze the effect of yoga on modifiable CVD risk factors. We systematically searched Ovid MEDLINE, Ovid Embase, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science from database inception in 1966 through June 2022 for studies evaluating the association between yoga and blood pressure, lipid profile, HbA1c and body mass index (BMI). Two investigators independently reviewed data. Conflicts were resolved through consensus. Random-effects meta-analyses were used. 64 RCTs including a total of 16,797 participants were eligible for inclusion in the meta-analysis. Yoga therapy improved both systolic as well as diastolic blood pressure (weight mean difference [WMD] (95% Confidence interval [CI]) of -4.56 [-6.37, -2.75] mm Hg, WMD [95% CI] - 3.39 [-5.01, -1.76] mm Hg respectively). There was also an improvement in BMI as well as hemoglobin A1c (HbA1c) (WMD [95% CI] of -0.57 [-1.05, -0.10] kg/m2, WMD [95% CI] of -0.14 [-0.24, -0.030] mmol/L respectively) . In addition, all parameters of the lipid profile, including low-density lipoprotein cholesterol (LDL-C) showed a significant improvement with yoga therapy (WMD [95% CI] -7.59 [-12.23, -2.95] mg/dL for LDL-C). Yoga has a modest yet positive effect on blood pressure, BMI, lipid profile and HbA1c and, therefore, may play an ancillary role in primary prevention of CVD.

RESUMEN
Background: There have been varying impacts of COVID-19 on racial, ethnic, and socioeconomic communities in the US. Recent literature suggests that Black Americans have the highest unadjusted and adjusted mortality rates from COVID-19, while White Americans have the lowest unadjusted and adjusted rates. However, the role of socioeconomic status and comorbidities in these disparities in health outcomes from COVID-19 are unclear. Thus, the purpose of this study is to evaluate how socioeconomic status and race impact COVID-19 outcomes in patients hospitalized with COVID-19 in a large health care system in the Mid-Atlantic region. Material and methods: We retrospectively analyzed the association of COVID-19 outcomes and race, ethnicity, and socioeconomic status using electronic medical records and the REDCap database from the time period of March 5, 2020 to June 3, 2020. The outcomes evaluated were intubation, ICU admission, and discharge destination. Multivariate logistic regression analysis was then performed to examine whether race and socioeconomic status were independent risk factors of mortality controlling for age, Charlson comorbidity index (CCI), and comorbidities. Results: Race was not found to be an independent predictor for COVID-19 inpatient mortality. Race was found to be an independent risk factor for ICU admission with odds of ICU admission for Black patients to be 1.5 times higher (odds ratio (OR) 1.4 1.07 to 2.04) compared to Non-Black/Non-White (72.4% identifying as Hispanic) but no difference between Black and White races. Race was found not to be an independent risk factor for intubation nor was race an independent risk factor for increased length of ICU LOS, hospital LOS or intubation days. Socioeconomic status was not an independent risk factor for inpatient mortality although high income groups were significantly less likely to be admitted to the ICU compared to middle income patients. Conclusion: Our cohort of patients in a large mid-Atlantic health system showed that there was no statistically significant difference between race or socioeconomic status and COVID-19 related inpatient mortality. However, Black patients and individuals in the lower to middle socioeconomic group had a higher rate of COVID-19 hospitalizations when accounting for age, sex, and comorbidities. With ongoing vaccination efforts, equitable administration of resources should focus on disproportionately affected populations.
RESUMEN
Our understanding of sex differences in subclinical atherosclerosis and plaque composition and characteristics have greatly improved with the use of coronary computed tomography (CCTA) over the past years. CCTA has emerged as an important frontline diagnostic test for women, especially as we continue to understand the impact of non-obstructive atherosclerosis as well as diffuse, high risk plaque as precursors of acute cardiac events in women. Based on its ability to identify complex plaque morphology such as low attenuation plaque, high risk non calcified plaque, positive remodeling, fibrous cap, CCTA can be used to assess plaque characteristics. CCTA can avoid false positive of other imaging studies, if included earlier in assessment of ischemic symptoms. In the contemporary clinical setting, CCTA will prove useful in further understanding and managing cardiovascular disease in women and those without traditional obstructive coronary disease.

BACKGROUND: Barth syndrome (BTHS) is a rare X-linked recessive disorder characterized by clinical features including cardiomyopathy, skeletal myopathy, neutropenia, growth delay, and exercise intolerance. It is often considered to be a paediatric disease, owing to most cases being diagnosed during childhood and mortality being the highest during the first few years of life. CASE SUMMARY: We report a case of dilated cardiomyopathy due to BTHS in a 27-year-old adult male patient, who initially presented with lightheadedness, dyspnoea, orthopnoea, and bilateral lower extremity oedema. Key findings from investigations included leukopenia, prolonged QTc interval, reduced left ventricular ejection fraction (LVEF), global enlargement of all heart chambers, patent coronary arteries, and mild pulmonary hypertension. The patient was diuresed to euvolemia and discharged with a LifeVest. Guideline-directed medical therapy was initiated and uptitrated as an outpatient. A repeat echocardiogram 2 years after initial presentation showed marked improvement in LVEF. DISCUSSION: It is possible that there are adult patients with idiopathic cardiomyopathy, which may be attributable to BTHS. In the absence of an obvious underlying cause, with the appropriate historical information, clinical exam, laboratory investigations, and imaging findings, BTHS should be considered as a likely cause of non-ischaemic cardiomyopathy.
RESUMEN
The shear stress and hypoxia in the pulmonary artery in patients with pulmonary arterial hypertension(PAH) causes endothelial dysfunction, smooth muscle proliferation and activation of thrombotic pathways leading to in situ thrombosis. Targeting the thrombotic pathways is a proposed mechanism to slow disease progression and improve survival. Over the years, the survival in patients with PAH has improved due to multiple factors with the increased use of anticoagulation as one of them. Both European Respiratory Society/European Society of Cardiology and American College of Cardiology/American Heart Association guidelines make grade II recommendations for using anticoagulation in PAH. The guidelines are based on weak observational studies with high risk of bias which have only studied warfarin as the choice of anticoagulation. In this article, we review the pathophysiology, rationale and the current literature investigating the role of anticoagulation in PAH.

A 26-year-old otherwise healthy man died of fulminant myocarditis. Nasopharyngeal specimens collected premortem tested negative for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Histopathological evaluation of the heart showed myocardial necrosis surrounded by cytotoxic T-cells and tissue-repair macrophages. Myocardial T-cell receptor (TCR) sequencing revealed hyper-dominant clones with highly similar sequences to TCRs that are specific for SARS-CoV-2 epitopes. SARS-CoV-2 RNA was detected in the gut, supporting a diagnosis of multisystem inflammatory syndrome in adults (MIS-A). Molecular targets of MIS-associated inflammation are not known. Our data indicate that SARS-CoV-2 antigens selected high-frequency T-cell clones that mediated fatal myocarditis.

COVID-19 became a global pandemic in early 2020. While well known for its pulmonary manifestations, the virus also has a number of cardiac manifestations as well. Takotsubo syndrome has scarcely been reported in patients with COVID-19, but it is possible that the cytokine storm associated with the infection can trigger Takotsubo syndrome in patients with underlying risk factors for Takotsubo (emotional distress, physical distress, history of psychiatric disorders).

Rhabdomyosarcoma is an aggressiveâ¯malignant soft-tissue sarcoma that develop from undifferentiated mesenchymal cells. Less than 1% of all adult solid malignant cancers are sarcomas, and RMSs represent less than 2-5% of adult sarcomas.â¯â¯ RMS is divided into three main subtypes: Embryonal, alveolar and pleomorphic RMS (PRMS).â¯â¯ Most common subtype in adults is PRMS. Most common primary sites are extremities, trunk wall, and genitourinary organs. Metastasis are often found at diagnosis. 5-year overall survival rates were reported in the Surveillance, Epidemiology, and End Results database (SEER) to be 63% for pediatric patients and 27% for adults. Given the rarity of theâ¯adultâ¯PRMS, variation in its clinical presentation, characteristics of the tumor itself and the prognosis; there are very limited data available to guide the management of adults withâ¯PRMS.â¯Herein we present a case report of pleomorphic rhabdomyosarcoma of the right thigh in a 60-year-old male who achieved aâ¯long-termâ¯survival (30 months) which was accomplished by multimodality treatment including surgery, radiotherapy, and chemotherapy.â¯â¯â¯.
RESUMEN
BACKGROUND Acute bacterial pericarditis is rare, and the incidence numbers have been declining in the modern antibiotic era. Purulent bacterial pericarditis is a fatal disease in which mortality rates can reach 100% if left untreated. CASE REPORT We present a case of primary purulent bacterial pericarditis with polymicrobial growth including Micromonas micro, Prevotella intermedia and Fusobacterium species, all of which are anaerobic flora of the oral cavity. Constant re-accumulation of the purulent pericardial effusion led the patient to have recurrent echocardiographic and clinical cardiac tamponade requiring recurrent pericardiocentesis' and eventually a pericardial window. CONCLUSIONS Although rare, bacterial pericarditis has been noted to lead to clinical and echocardiographic tamponade. Early diagnosis and treatment are necessary for improving clinical outcomes. It is important to have a suspicion for purulent pericarditis, due to its high level of mortality, in patients who present with non-specific symptoms and pleuritic chest pain.

Papillary fibroelastomas are a rare cardiac neoplasm typically found on the left side of the heart, and most commonly on the aortic valve, which can present with cardiac or neurologic symptoms. A 51-year-old woman with no cardiac history presented to a resident clinic with complaints of left-sided facial paresthesias and palpitations for 1 month. Echocardiographic imaging showed a mass on the aortic annulus, concerning for a cardiac tumor. Due to the risk of possible embolization, if the tumor was a myxoma, the patient required intrathoracic surgery. During the intrathoracic procedure the mass was confirmed to be a papillary fibroelastoma and the patient had the mass removed without any complications. Papillary fibroelastomas are found in less than 1% of the population but can present clinically with a wide variety of symptoms. Patients with this neoplasm are at risk for severe complications, due to embolization, potentially causing cerebrovascular accidents or myocardial infarctions. We present a case of a papillary fibroelastoma producing both cardiac and neurologic symptoms.
RESUMEN
BACKGROUND: SARS-CoV-2 is a novel viral illness originating out of Wuhan China in late 2019. This global pandemic has infected nearly 3 million people and accounted for 200 000 deaths worldwide, with those numbers still climbing. CASE SUMMARY: We present a 54-year-old patient who developed respiratory failure requiring endotracheal intubation from her infection with SARS-CoV-2. This patient was subsequently found to have a right ventricular thrombus and bilateral pulmonary emboli, likely contributing to her respiratory status. On the 14th day of hospitalization, the patient was successfully extubated, and 5 days later was discharged to the rehabilitation unit. DISCUSSION: SARS-CoV-2 presents primarily with pulmonary symptoms; however, many patients, particularly those who are severely ill, exhibit adverse events related to hypercoagulability. The exact mechanism explaining this hypercoagulable state has yet to be elucidated, but these thrombotic events have been linked to the increased inflammation caused by SARS-CoV-2. This novel viral illness is still largely misunderstood, but the hypercoagulable state, seen in severely ill patients, appears to play a major role in disease progression and prognosis.
RESUMEN
BACKGROUND Coronavirus disease 2019 (COVID-19) is primarily a respiratory illness. However, with rising numbers of cases, multiple reports of cardiovascular manifestations have emerged. We present a case of COVID-19 infection complicated by myopericarditis and tamponade requiring drainage. CASE REPORT An 82-year-old woman with multiple comorbidities presented with five days of productive cough, fever with chills, and intermittent diarrhea. She tested positive for COVID-19. Index EKG revealed new diffuse T-wave inversions and a prolonged QT interval (>500 ms). Troponin was mildly elevated without any anginal symptoms. Hydroxychloroquine and azithromycin were not initiated due to concerns about QT prolongation. The echocardiogram revealed preserved left ventricular (LV) function, a small global pericardial effusion, and apical hypokinesis. Serial echocardiograms revealed an enlarging circumferential pericardial effusion with pacemaker wire reported as 'piercing' the right ventricular (RV) apex alongside early diastolic collapse of the right ventricle, suggesting echocardiographic tamponade. Chest CT revealed extension of the RV pacemaker lead into the pericardial fat. Interestingly, on comparison with a previous chest CT from 2019, similar lead positions were confirmed. Pericardiocentesis was performed with removal of 400 cc exudate. CONCLUSIONS Acute myopericarditis and pericardial effusion can occur in COVID-19 infection, even in the absence of severe pulmonary disease. This case highlights the importance of awareness of rare cardiac manifestations of COVID-19 in the form of acute myopericarditis and cardiac tamponade and their early diagnosis and management.
