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.

(1→3)-ß-D-Glucan Assay in Monitoring Response to Anti-Fungal Therapy in Fungal Endocarditis.

BACKGROUND AND AIM OF THE STUDY: A case is reported of Candida glabrata infective endocarditis (IE) treated without surgical intervention. The study aim was to: (i) briefly discuss the outcomes of other documented cases of fungal IE managed medically with fluconazole; (ii) discuss the (1→3)-ß-D-glucan assay and its previously studied role in the diagnosis of invasive fungal infections; and (iii) examine a possible application of the (1→3)-ß-D-glucan assay to monitor response to antifungal treatment in patients with Candida endocarditis. METHODS: The serum Fungitell assay was used to trend (1→3)-ß-D-glucan in a patient with Candida endocarditis to determine treatment effectiveness with fluconazole, to provide an appropriate end date for antifungal therapy, and to survey infection suppression while off treatment. RESULTS: The (1→03)-ß-D-glucan assay began trending downwards at 197 days into treatment with oral fluconazole. After 16 months of therapy, fluconazole was stopped due to transaminitis. (1→3)-ß-Dglucan levels were checked six weeks after the discontinuation of treatment and were negative. The patient has now been off therapy for 21 weeks with no signs of clinical disease, and values remain negative. CONCLUSIONS: The present case indicates that a trending (1→3)-ß-D-glucan assay may have valuable application in monitoring treatment response and infection suppression for Candida endocarditis.

Unusual Presentation of Post-coital Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection (SCAD) is a grave medical condition that is defined as a separation of the coronary artery wall layer. This presentation is rare in males and can be triggered by cardio-circulatory stress, such as exercise and emotional stress. Sexual intercourse is considered potent cardiovascular stress that can be strenuous and cause rapid and significant changes in the heart rate and blood pressure which can predispose SCAD. Herein, we are reporting a very rare case of a 41-year-old male gentleman who presented with SCAD after vigorous sexual intercourse. We are reporting this case to encourage physicians to educate their patients on the topic.

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.

Left ventricular aneurysm and ventricular tachycardia as initial presentation of cardiac sarcoidosis.

CONTEXT: Cardiac sarcoidosis (CS) is a rare, potentially fatal disease. It has a wide range of clinical presentations that range from asymptomatic electrocardiogram changes to sudden cardiac death. Ventricular aneurysms and ventricular tachycardia are seen late in the disease, and are rarely the presenting manifestation of the disease. Diagnosis of CS is challenging and often missed or delayed. CASE REPORT: We report a 35-year-old patient who presented with sustained ventricular tachycardia and ST-elevation on electrocardiogram. Cardiac catheterization showed normal coronaries and left ventricular aneurysm. Subsequent 2D-echocardiography showed an infiltrative disease pattern. Cardiac MRI was done and showed late gadolinium enhancement in the septum, apex and lateral wall. The patient was diagnosed with cardiac sarcoidosis and treated with immune suppression and antiarrhythmic agent. In addition underwent AICD implantation. CONCLUSION: Our case highlights the importance of suspecting cardiac sarcoidosis in young patients presenting with electrocardiogram changes, and present an atypical presentation of this disease.

Giant dissecting aortic aneurysm in an asymptomatic young male.

Giant aortic aneurysm is defined as aneurysm in the aorta greater than 10 cm in diameter. It is a rare finding since most patients will present with complications of dissection or rupture before the size of aneurysm reaches that magnitude. Etiological factors include atherosclerosis, Marfan's syndrome, giant cell arteritis, tuberculosis, syphilis, HIV-associated vasculitis, hereditary hemorrhagic telangiectasia, and medial agenesis. Once diagnosed, prompt surgical intervention is the treatment of choice. Although asymptomatic unruptured giant aortic aneurysm has been reported in the literature, there has not been any case of asymptomatic giant dissecting aortic aneurysm reported in the literature thus far. We report a case of giant dissecting ascending aortic aneurysm in an asymptomatic young male who was referred to our institution for abnormal findings on physical exam.

Takotsubo Syndrome in African American vs. Non-African American Women.

OBJECTIVES: Takotsubo syndrome (TTS) is a reversible cause of heart failure rarely described in African-American patients. This study aimed to compare and contrast the clinical characteristics of TTS in African-American (AA) and non-African-American (NAA) patients. METHODS: We retrospectively reviewed the charts of eight patients (four AA and four NAA) diagnosed with TTS, between June 2006 and August 2008, in four different teaching hospitals: St Michael's Medical Center, St Joseph's Medical Center, Trinitas hospital and St Louis' University Hospital. We compared the patients with regard to presenting symptoms, precipitating stressors, electrocardiographic findings, troponin levels, ejection fraction and in-hospital course. RESULTS: All patients were females (mean age 64 for AA and 67 for NAA). All patients experienced chest pain and had elevated troponin levels. Two AA and three NAA patients had associated shortness of breath and one NAA had syncope. All AA and three NAA had T-wave inversions. Three NAA and one AA had ST segment elevation. Three patients in both groups developed prolongation of the QT interval. Coronary angiograms did not reveal any significant obstructive coronary artery disease. Three patients, all NAA, needed hemodynamic support during their hospital stay but none died. CONCLUSION: AA and NAA women with TTS have similar presenting symptoms but may differ in the electrocardiographic findings and in-hospital course of the disease.
