Management of Wolff-Parkinson-White Syndrome in a Patient with Post-partum Cardiomyopathy.

Wolf-Parkinson-White (WPW) syndrome is a congenital heart condition in which the atrioventricular (AV) node is bypassed by an accessory pathway that connects the atria and ventricle directly. WPW syndrome in patients with a history of peripartum cardiomyopathy (pregnancy-related cardiomyopathy) is associated with a high risk of morbidity and mortality secondary to failure of the pump and the conduction system of the heart. Management of these cases deals with arrhythmia and systolic heart failure, which becomes more challenging in pregnant patients as it requires treatment methods that minimize risks to the fetus. We report a case of a young female patient with WPW syndrome and postpartum cardiomyopathy presenting with symptomatic arrhythmias (tachycardia).

Where is the Thrombus ? Mural Ascending Aortic Thrombus with Embolic Events in a Patient with Recent COVID 19 Infection.

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a global health pandemic that led to substantial morbidity and mortality worldwide. The virus has been known to predominantly cause severe hypoxemic respiratory failure but there have been multiple reports of extra-pulmonary manifestations. Additionally, there has been increasing evidence of COVID-19 hyper-coagulability. Herein, we present a case of a 49-year-old male with a past medical history of diet controlled type II diabetes mellitus and recently diagnosed COVID-19 who presented to the emergency department with a chief complaint of nausea and vomiting. Our patient was found to have a thrombus-like appearing 1.9 cm × 1.2 cm well-circumscribed mass, attached to the greater curvature of the ascending aorta, superior to the right coronary cusp of the aortic valve almost three weeks after his initial diagnosis of COVID-19 virus.

A Rare Case of Eustachian Valve Endocarditis in a Young Male With Poorly Controlled Type 1 Diabetes Mellitus.

The eustachian valve (EV) is a vestigial structure found at the junction of the inferior vena cava and the right atrium, a remnant of the embryological sinus venosus that may persist throughout life. Right-sided infective endocarditis of the eustachian valve remains a distinctly rare and under-diagnosed entity. Commonly known risk factors of eustachian valve endocarditis (EVE) are intravenous drug use, in-dwelling intracardiac devices, and central lines, although more recently immunocompromised states, e.g. uncontrolled diabetes mellitus and old age, have been recognized as risk factors for the disease. Although Staphylococcus aureus has been the most commonly implicated organism, cases of infections with gram-negative organisms are emerging. We present a 47-year-old male with uncontrolled type 1 DM who initially presented to the ED with complaints of low back pain and dysuria and was later found to have eustachian valve endocarditis ultimately treated with intravenous antibiotics.

Fever and Hyponatremia Unmasking Brugada Pattern Electrocardiogram in a Patient With SARS-CoV-2 Infection.

Brugada syndrome is an autosomal dominant genetic disorder that primarily affects myocardial sodium channels and has been associated with an increased risk of ventricular tachyarrhythmias and sudden cardiac death. Here, we report a case of a 58-year-old Hispanic male with a history significant for prior pulmonary tuberculosis infection who presented with pleuritic left-sided chest pain associated with body aches, productive cough, fevers, and chills and was found to be positive for SARS-CoV-2 by real-time reverse-transcription-polymerase chain reaction (rRT-PCR). Electrocardiogram (ECG, EKG) on presentation demonstrated a coved ST-segment elevation in V1-V2, suggesting Brugada pattern type 1 without evidence of ischemic changes. EKG changes normalized once fever and hyponatremia improved.

Management of Wolff-Parkinson-White syndrome in a patient with peripartum cardiomyopathy.

Wolf-Parkinson-White (WPW) syndrome is a congenital heart condition in which the atrioventricular (AV) node is bypassed by an accessory pathway that connects the atria and ventricle directly along with symptoms of syncope or palpitations. WPW syndrome in patients with a history of peripartum cardiomyopathy (pregnancy-related cardiomyopathy) is associated with a high risk of morbidity and mortality secondary to failure of the pump and the conduction system of the heart. Management of these cases deals with arrhythmia and systolic heart failure, which becomes more challenging in pregnant patients as it requires treatment methods that minimize risks to the fetus. We report a case of a young female patient with WPW syndrome and peripartum cardiomyopathy presenting with symptomatic arrhythmias (tachycardia).

Does Baseline Diuretics Use Affect Prognosis in Patients With COVID-19?

The rapid emergence of coronavirus disease 2019 (COVID-19) has become the biggest healthcare crisis of the last century, resulting in thousands of deaths worldwide. There have been studies that evaluated the role of angiotensin-converting enzyme (ACE) inhibitors (ACEi) and angiotensin receptor blockers (ARBs) in treating patients with COVID-19. However, the prior use of diuretics and their effect on mortality in this setting remains unknown. The aim of the study was to evaluate the effect of diuretics in patients admitted with COVID-19. The current study was conducted between March 15, 2020, and April 30, 2020, during the COVID-19 pandemic in three different hospitals in Northern New Jersey, USA. The primary outcome was survival or in-hospital mortality from COVID-19 from the day of admission. The secondary outcome was severe or non-severe illness from COVID-19. This retrospective study included a total of 313 patients with a median age of 61.3 ± 14.6 years. There was a total of 68 patients taking diuretics at home and 245 patients who were not taking diuretics. There was a total of 39 (57.35%) deaths in patients taking diuretics as compared to 93 (37.96%) deaths in patients not taking diuretics (p-value 0.0042). Also, 54 (79.41%) patients who took diuretics had severe COVID-19 illness as compared to 116 (47.35%) who did not take diuretics (p-value <.0001). However, after adjusting for the confounding factors, there was no difference in mortality or severity of illness in COVID-19 patients taking diuretics at the time of admission. In conclusion, there was no effect of the baseline use of diuretics in the prognosis of COVID-19.

Misoprostol-induced Coronary Vasospasm Complicated by Takotsubo Cardiomyopathy and Cardiac Arrest.

Misoprostol is a synthetic E1 prostaglandin commonly used to induce abortion in the United States and elsewhere. There is limited literature on the cardiovascular adverse effects of misoprostol, and, to the best of our knowledge, very few such events have been reported. We describe the case of 52-year-old woman who was given misoprostol for cervical softening before endometrial ablation and experienced a cardiac arrest due to coronary vasospasm. She was successfully resuscitated and echocardiography showed features consistent with Takotsubo cardiomyopathy. Coronary angiography revealed coronary artery spasm which responded to nitroglycerin. Our case adds to the limited literature on this life-threatening adverse event of misoprostol. LEARNING POINTS: Misoprostol is frequently used obstetrics and gynaecology and routinely for the medical termination of pregnancy.Misoprostol can result in cardiac arrest due to coronary vasospasm.Coronary vasospasm induced by misoprostol can be relieved with intra-arterial nitroglycerin.

A Case of STEMI Masquerading Brugada Syndrome: Emphasizing the Importance of Clinical Decision Making in Emergencies.

Brugada syndrome is a rare arrhythmogenic syndrome that is associated with an increased risk of ventricular fibrillation and sudden cardiac death. Electrocardiographic findings include patterns similar to a right bundle branch block (RBBB) and persistent ST-segment elevation in precordial leads (V1 and V2). There are numerous reports of Brugada syndrome mimicking ST-segment elevation myocardial infraction (STEMI); however, we describe a case of 47-year-old male who presented with STEMI mimics Brugada syndrome with preexisting RBBB. The patient developed polymorphic ventricular tachycardia generating into ventricular fibrillation right before catheterization making the diagnosis more challenging. The patient, eventually, was found to have obstructive coronary artery disease and no evidence of abnormal sodium channelopathy on further testing. This case highlights the importance of meticulous history taking and appropriate diagnostic test in establishing proper diagnosis of STEMI in a patient with preexisting RBBB, which can mimic Brugada syndrome.

Characteristics and outcomes of patients with COVID-19 in an intensive care unit of a community hospital; retrospective cohort study.

Background: The limited data available so far has shown a high mortality rate among COVID-19 patients admitted to the ICU. Possible risk factors for poor outcomes in this type of patients need to be analyzed so we can identify strategies to reduce mortality. Objective: Characterized the COVID-19 experience in Community hospital ICU. Methods: Single center retrospective cohort study involving all adult patients admitted to the ICU with severe COVID-19 infection. Results: 132 patients were admitted to ICU during the study period. There was a preponderance for males and the most common ethnicity was Hispanic. The overall mortality was 69%, and mortality after intubation was 76%. In the multivariable analysis older Age (OR = 15.7), Obesity (OR = 2.92) and Mechanical Ventilation (OR = 12.0) were found to be a significant independent risk factor for increased mortality. Conclusion: Our study confirms the high mortality rate in patients critically ill with COVID-19 requiring ICU care especially among older age group, mechanically ventilated and obese patients. Overall outcomes are comparable to larger tertiary care centers. Our findings highlight the need to plan for optimal resource allocation and tailoring therapies to target the disease so as to improve outcomes.

A STEMI mimic (Brugada ECG pattern) unveiled by influenza fever.

Brugada syndrome is a genetic disease with a characteristic electrocardiogram (ECG) findings of ST elevation in leads V1-V3 with a right bundle branch block (RBBB) appearance called Brugada ECG pattern and a tendency to develop malignant polymorphic ventricular arrhythmias that may lead to syncope or cardiac arrest. Common triggers for Brugada ECG pattern include fever, tricyclic antidepressants, lithium, cocaine and alcohol. This ECG pattern together with clinical findings mentioned above is termed Brugada Syndrome. We report a case of a 51-year-old male with a past medical history of hypertension presented to emergency department with 2-day complaint of fever, chills, sore throat, nasal congestion, malaise, productive cough, was positive for Influenza B and on ECG found to have type-I (coved) Brugada ECG pattern. Influenza fever associated with Brugada ECG pattern is a rare manifestation; in fact, to the best of our knowledge, only three case reports have been published in the literature to date.

The utility of bedside echocardiography in critically ill COVID-19 patients: Early observational findings from three Northern New Jersey hospitals.

INTRODUCTION: Cardiovascular complications related to coronavirus disease 2019 (COVID-19) have led to the need for echocardiographic services during the pandemic. The present study aimed to identify the echocardiographic findings in hospitalized COVID-19 patients and their utility in disease management. METHODS: We included patients who were diagnosed with COVID-19 using polymerase chain reaction and those who underwent echocardiographic examination during their hospitalization. RESULTS: Altogether, 45 patients were evaluated. The mean age was 61.4 ± 12.2 years. Hypertension (n = 29, 64%) and diabetes mellitus (n = 25, 55%) were the most common comorbidities followed by congestive heart failure (n = 11, 24%), coronary artery disease (n = 9, 20%), and valvular heart disease (n = 3, 7%). Eight patients (18%) showed evidence of myocardial injury, as suggested by elevated troponin levels. Brain natriuretic peptide was elevated in 14 patients (36%), and 14 patients had left ventricular dysfunction in the form of reduced ejection fraction (31%). Right ventricular (RV) dilatation was observed in six patients, and five patients had reduced RV ejection fraction. RV pressure and volume overload were observed in three patients. RV thrombus was observed in one patient. Pulmonary pressure was elevated in 10 patients (24%). CONCLUSION: Two-dimensional echocardiography can be an important bedside tool for the assessment of cardiovascular abnormalities and hemodynamic status of COVID-19 patients.

A Rare Case of Myocarditis Mimicking ST-Elevation Myocardial Infarction.

Myocarditis is caused by acute injury and inflammation of cardiac myocytes and is most commonly caused by a viral infection. Myocarditis remains a rare diagnosis and manifests with a wide spectrum of non-specific symptoms that include chest pain, dyspnea, and palpitations associated with electrocardiographic abnormalities that resemble that of ST-elevation myocardial infarction (STEMI). Therefore, clinical diagnosis is often challenging and is often misdiagnosed. We present a case of a 22-year-old male who presented with left-sided non-radiating chest pain associated with shortness of breath, elevated troponin of 3.2 ng/ml (<0.03 ng/ml). Electrocardiogram (ECG) and cardiac echocardiogram revealed ST-segment elevations in the anterolateral leads and an ejection fraction of 35%, respectively. The patient was initially suspected of having a STEMI; however, cardiac catheterization revealed non-obstructed coronary arteries. Due to elevated inflammatory markers, the patient was then started on colchicine for suspected myocarditis and had complete resolution of symptoms one week after. This case highlights that a high index of clinical suspicion and prompt diagnosis is necessary to prevent any delays in appropriate therapy for myocarditis.

Coronary risk equivalence of diabetes assessed by SPECT-MPI.

BACKGROUND: Several publications and guidelines designate diabetes mellitus (DM) as a coronary artery disease (CAD) risk equivalent. The aim of this investigation was to examine DM cardiac risk equivalence from the perspective of stress SPECT myocardial perfusion imaging (MPI). METHODS AND RESULTS: We examined cardiovascular outcomes (cardiac death or nonfatal MI) of 17,499 patients referred for stress SPECT-MPI. Patients were stratified into four categories: non-DM without CAD, non-DM with CAD, DM without CAD, and DM with CAD, and normal or abnormal perfusion. Cardiac events occurred in 872 (5%), with event-free survival best among non-DM without CAD, worst in DM with CAD, and intermediate in DM without CAD, and non-DM with CAD. After multivariate adjustment, risk remained comparable between DM without CAD and non-DM with CAD [AHR 1.0 (95% CI 0.84-1.28), P =0.74]. Annualized event rates for normal subjects were 1.4% and 1.6% for non-DM with CAD and DM without CAD, respectively (P = 0.48) and 3.5% (P = 0.95) for both abnormal groups. After multivariate adjustment, outcomes were comparable within normal [AHR 1.4 (95% CI 0.98-1.96) P = 0.06] and abnormal [AHR 1.1 (95% CI 0.83-1.50) P = 0.49] MPI. CONCLUSIONS: Diabetic patients without CAD have comparable risk of cardiovascular events as non-diabetic patients with CAD after stratification by MPI results. These findings support diabetes as a CAD equivalent and suggest that MPI provides additional prognostic information in such patients.

The obesity paradox: the protective effect of obesity on right ventricular function using echocardiographic strain imaging in patients with pulmonary hypertension.

BACKGROUND: Obesity is associated with right ventricular (RV) dysfunction, but its effect on RV remodeling in patients with pulmonary hypertension (PHTN) has not been studied. We evaluated the effect of obesity, and its interplay with diabetes, in patients with PHTN using RV echocardiographic strain imaging. METHODS: One hundred eighty-five patients underwent echocardiographic imaging and pulmonary artery pressure was calculated using tricuspid regurgitation jet velocity. From focused RV apical-four-chamber view, global and mid peak systolic RV free wall longitudinal strain (FWLS) was calculated using speckle-tracking software. RESULTS: Global and mid RV FWLS in patients with PHTN (N.=84) was lower (-16.8±7 vs. 18.9±6.3, P=0.035 and -11.2±12.8 vs. -18.9±9.2, P=0.002 respectively) compared with patients without PHTN (N.=101). Among patients without PHTN, obese patients (BMI>30) had lower global and mid RV FWLS (-17.2±6.2 vs. -20.3±5.7, P=0.012 and -17.6±7.2 vs. -21.9±7.3, P=0.004), even after excluding diabetic patients (Mid RV FWLS -18.2±6.8 vs. -22.1±8, P=0.032). Among patients with PHTN, obese patients had similar RV FWLS compared with non-obese patients (P=0.46). However, on excluding diabetic patients from PHTN group, obese patients with PHTN had higher global and mid RV FWLS (-21.7±5.7 vs. -16.1±8, P=0.017 and 23.8±4.8 vs. -17±9.4, P=0.009 respectively) compared to non-obese patients which suggests a protective effect of obesity on RV function in patients with PHTN. CONCLUSIONS: Obesity is associated with subclinical RV dysfunction as assessed by RV strain imaging, but paradoxically it may confer a protective effect on RV function once the patient develops PHTN. Future studies should evaluate the clinical impact of this paradox.

Isolated Pulmonary Valve Fungal Endocarditis with Candida parapsilosis: Management Considerations of a Rare Case.

Pulmonary valve infections without the involvement of other valves account for only 1.5- 2% of all infective endocarditis cases. Isolated pulmonary valve endocarditis due to fungus is extremely rare. The case is presented of a 36-year-old male who was found to have isolated pulmonary valve endocarditis caused by a very rare organism, Candida parapsilosis, and that was solely managed with medical therapy. The patient was evaluated for three weeks of lowgrade fever, generalized rash and fatigue, and found to have C. parapsilosis in the blood. Transesophageal echocardiography (TEE) demonstrated a 4.5 cm vegetation on the pulmonary valve, without involvement of other valves. The patient was deemed not to be a surgical candidate and was subsequently started on intravenous liposomal amphotericin B and 5-flucytosine, with excellent clinical outcome. Based on these case details, it must be emphasized that in selective cases and if there are no known complications, fungal endocarditis can be managed successfully using anti-fungal agents.

Resting perfusion MPI-SPECT combined with cardiac 123I-mIBG sympathetic innervation imaging improves prediction of arrhythmic events in non-ischemic cardiomyopathy patients: sub-study from the ADMIRE-HF trial.

BACKGROUND: Delayed Iodine-123 meta-iodobenzylguanidine heart/mediastinum (H/M) uptake ratio predicted arrhythmic events in patients with heart failure (HF) and significant left ventricular dysfunction in ADMIRE-HF. We tested the hypothesis that resting perfusion defects on MPI-SPECT, representing scar, would further risk stratify patients beyond H/M ratio in the prediction of ventricular arrhythmic events in both ischemic (ICM) and non-ischemic cardiomyopathy (NICM) patients. METHODS: Patients from the ADMIRE-HF database were classified as ICM and NICM and were stratified by delayed H/M ratio (<1.6/≥1.6) and by summed rest score (SRS) (≤8/>8) on MPI-SPECT. The entire cohort was also classified as high risk (H/M <1.6, SRS >8) and low risk (H/M ≥1.6, SRS ≤8). Scores were from visual interpretation of individual and derived consensus (average) reads per ASNC guidelines. RESULTS: There were 612 (66%) ICM and 317 (34%) NICM patients. ICM patients had higher mean SRS than NICM patients (25 ± 13 vs 12 ± 10). Sixty-three arrhythmic events occurred over a median follow-up of 17 months. SRS had incremental predictive value among NICM patients with low H/M ratio (<1.6). There was no risk stratification in patients with ICM. Multivariable analysis for NICM with H/M ratio <1.6 demonstrated SRS score >8 as the only independent predictor of arrhythmic events (hazard ratio 3.3, 95% CI 1.1-9.8, P = .03). Patients classified in high-risk subgroup had statistically significant increased risk of arrhythmic events (hazard ratio 2.080, 95% CI 1.112-3.894, P = .022). There was only one event in low-risk subgroup with a trend towards lower risk of arrhythmic events (P = .07). CONCLUSION: Resting perfusion defects provide independent risk stratification in addition to Iodine-123 meta-iodobenzylguanidine sympathetic innervation imaging in predicting arrhythmic events in patients with NICM and HF. High and potentially low-risk groups for arrhythmic events can be identified based on the severity of resting perfusion defect score and H/M ratio.

Appropriateness criteria are an imprecise measure for repeat echocardiograms.

BACKGROUND: Previous studies have reported that most transthoracic echocardiograms meet current ACC/ASE appropriateness criteria, but efficacy of appropriateness criteria for repeat echocardiograms has not been investigated. We sought to prospectively determine whether current appropriateness criteria accurately assess the need for repeat echocardiograms in a consecutive series of inpatients in a tertiary care community teaching hospital. METHODS AND RESULTS: Appropriateness criteria were assessed for consecutive echocardiograms ordered over 30 days. Ordering clinician specialty and level of training were recorded. For repeat echocardiograms, change in clinical status between first and second echocardiogram and any change in echocardiographic findings were documented. Out of 574 echocardiograms analyzed, 143 repeat studies were performed in 104 patients. Level of appropriateness for first time studies was estimated at 84.6% and for repeat studies at 73.4% (x(2) = 7.71, P = 0.005). Of those patients receiving at least 1 repeat echocardiogram 42 patients (40%) experienced no detectable change in clinical status or other reason that would justify a repeat study. New echocardiographic findings were found in slightly more than half (52%) of patients receiving repeat studies. CONCLUSIONS: Inappropriate repeat echocardiograms are ordered more frequently than first time studies. A significant proportion of repeat echocardiograms do not appear to be justified, and often yield no new echocardiographic findings. Our data suggest that current appropriateness criteria might benefit from further revision with particular regard to justification for repeat studies.
