ABSTRACT
Background: Current guidelines recommend proceeding with cardioversion, without the explicit need for preprocedural transesophageal echocardiography (TEE), in patients compliant with oral anticoagulation for at least 3 weeks. The relevance of these guidelines remains unclear in those undergoing repeat cardioversion. Case summary: A 66-year-old male with a history of atrial fibrillation (AF) and a left atrial appendage occlusion (LAAO) device, compliant with apixaban, presented with dyspnea and lightheadedness. He was cardioverted into sinus rhythm, 10 days before symptom onset, with TEE unremarkable at the time. An ECG revealed that the patient converted back into AF and a repeat cardioversion was scheduled. At the patient's request, a TEE was obtained, revealing a new 2 cm×1 cm thrombus in the left atrium above the WATCHMAN device. Cardioversion was canceled and the patient was hospitalized for AF management. Discussion: Cardioverted patients are at risk for thrombus formation due to atrial stunning, a transitory dysfunction of the atrial appendage and atrium, which occurs immediately after cardioversion and can persist for several weeks. The likelihood of a thrombus is further propagated by individual risk factors for stroke. Conclusion: Anticoagulation does not eliminate the risk of thrombus formation in those with increased risk factors for stroke. Further studies are warranted to assess the need for routine TEE, after cardioversion, in those with stroke risk factors on anticoagulation or who have LAAO.
ABSTRACT
Background: Cardiac troponin (cTn) can also be elevated in patients with non-cardiac illnesses. The utility of elevated cTn in patients with acute gastrointestinal bleeding (AGIB) is unclear. Methods: We retrospectively identified all patients admitted with AGIB who had cTn ordered. We assessed the prevalence, predictors and mortality. Results: A total of 172 patients with AGIB were included in the study, of whom 17% had abnormal cTn. Predictors of elevated cTn were advanced age, lower BMI, coronary artery disease and chronic kidney disease. The abnormal cTn group had more cardiac consultation and procedures and longer length of stay. However, there was no difference in mortality between the two groups. Conclusion: Elevated cTn in patients with AGIB was associated with more cardiology consultation and downstream cardiac testing, greater delay to endoscopic evaluation and longer length of stay, without significantly affecting the mortality.
Cardiac troponin (cTn) is a type of protein found in the heart muscles. It is released into the bloodstream when heart muscles become damaged. However, cTn can also be elevated in patients with non-cardiac illnesses, such as critically ill patients and patients with acute gastrointestinal bleeding (AGIB). This study analyzed the relationship between elevated cTn and the outcomes (including prevalence, predictors and mortality) in patients with AGIB. A total of 172 patients with AGIB were evaluated. They were divided into groups based on the presence of elevated cTn. The prevalence of elevated cTn in AGIB patients was 17%. Older age, lower BMI, coronary artery disease and chronic kidney disease were found to be some of the factors that can predict cTn elevation in AGIB patients. AGIB patients with elevated cTn had more cardiology service consultations and procedures and longer lengths of hospital stay. However, there was no effect of elevated cTn on the death rate of AGIB patients.

Cardiovascular complications contribute to approximately 40% of all COVID-19-related deaths. Thrombosis in COVID-19 infection is a well-known phenomenon, and the spectrum of thromboembolic diseases related to COVID-19 is wide, with venous thromboembolism being the most common manifestation. We describe a case of myocardial infarction with nonobstructive coronary arteries (MINOCA) that developed in the setting of mild COVID-19 infection. Our case illustrates how COVID-19 can present with MINOCA and highlights the importance of cardiac magnetic resonance imaging in identifying the underlying etiology.
ABSTRACT
Left atrial appendage closure (LAAC) has evolved as a safe alternative to oral anticoagulation therapy for stroke prophylaxis. However, the presence of a patent foramen ovale (PFO) occluder device is considered a relative contraindication. Here we report a successful case of LAAC in the presence of a PFO occluder device. (Level of Difficulty: Beginner.).
ABSTRACT
The use of intravenous (IV) oxytocin has been commonly associated with the development of nausea, vomiting, headache, flushing, and hypotension. To date, only a few previously published studies have linked the administration of IV oxytocin, in high doses exceeding 15 mU/min, with the development of acute pulmonary edema. In this article, we aim to report the rare occurrence of acute pulmonary edema following administration of IV oxytocin at a small dose of 2 mU/min, in a 20-year-old pregnant female, to allow its recognition and prompt treatment by the clinician caring for the patient.
ABSTRACT
BACKGROUND: Acquired thrombocytopenia (aTP) is associated with a high frequency of bleeding and ischemic complications in patients undergoing percutaneous coronary intervention (PCI). Herein, we report a meta-analysis evaluating the adverse effects of aTP on cardiovascular outcomes and mortality post-PCI. METHODS: A literature search was performed using PubMed, Embase, Cochrane and, clinicaltrials.gov from the inception of these databases through October 2019. Patients were divided into two groups: 1) No Thrombocytopenia (nTP) and 2) Acquired Thrombocytopenia (aTP) after PCI. Primary endpoints were in-hospital, 30-day and all-cause mortality rates at the longest follow-up. The main summary estimate was random effects Risk ratio (RR) with 95% confidence intervals (CIs). RESULTS: Seven studies involving 57,247 participants were included. There was significantly increased in-hospital all-cause mortality (HR 10.73 [6.82-16.88]), MACE (HR 2.96 [2.24-3.94]), major bleeding (HR 4.78 [3.54-6.47]), and target vessel revascularization (TVR) (HR 7.53 [2.8-20.2]), in the aTP group compared to the nTP group. Similarly, aTP group had a statistically significant increased incidence of 30-day all-cause mortality (HR 6.08), MACE (HR 2.77), post-PCI MI (HR 1.98), TVR (HR 5.2), and major bleeding (HR 12.73). Outcomes at longest follow-up showed increased incidence of all-cause mortality (HR 3.98 [1.53-10.33]) and MACE (HR 1.24 [0.99-1.54]) in aTP group, while there was no significant difference for post-PCI MI (HR 0.94 [0.37-2.39]) and TVR (HR 0.96 [0.69-1.32]) between both groups. CONCLUSIONS: Acquired Thrombocytopenia after PCI is associated with increased morbidity, mortality, adverse bleeding events and the need for in-hospital and 30-day TVR.

BACKGROUND: Cardiac troponin (cTn) is mainly used to diagnose acute coronary syndrome (ACS). However, cTn can also be elevated in critically ill patients secondary to demand ischemia or myocardial injury. The impact of cardiology consultation on the clinical outcomes of patients admitted to medical intensive care unit (ICU) with elevated cTn is unclear. METHODS: A retrospective analysis of medical ICU patients with elevated cTn without evidence of ACS between January 2013 through December 2018. Patients were stratified based on documentation of cardiology consultation. The primary outcome was 1-year mortality. Secondary outcomes were in-hospital and 30-day mortality, the length of stay (LOS), further cardiac testing, 30-day readmission rate, new prescription of cardiac medications, and the predictors of a cardiology consultation. RESULTS: Of 846 patients screened, 766 patients were included, of whom 63.2% had cardiology consultation. Cardiology consultation group had longer median LOS (7 vs. 5 days, P = 0.007), additional cardiac testing (90.3% vs. 67.7%, P < 0.001), and more new cardiac medications (52.1% vs. 16.3%, P < 0.001). No difference was noted in-hospital mortality (adjusted odds ratio [aOR], 0.6, 95% CI, 0.4-1.1, P = .117), 30-day mortality (aOR = 0.8, 95% CI, 0.5-1.4, P = .425), 1- year mortality (aOR, 1.4, 95% CI, 0.9-2.2, P = .193), or cardiac-specific 30-day readmission rate (aOR, 7.0, 95% CI, 0.7-14.9, P = .137). History of coronary artery disease (CAD) was the most independent predictor for a cardiology consult (aOR, 2.2, 95% CI, 1.3-3.8, P < .001). CONCLUSION: Cardiology consultation for elevated cTn in medical ICU patients was associated with increased cardiac testing and LOS, without significant impact on mortality.

Cerebrovascular disease is the second leading cause of death in the United States in adults aged 65 years and older and is most commonly caused by atherosclerosis. More so, cryptogenic strokes account for one-third of all ischemic strokes. At the same time, iron deficiency anemia is prevalent worldwide and mostly affects females of childbearing age. Here we report a case of a 42-year-old female who presented with symptoms of acute ischemic stroke and was found to have severe iron deficiency anemia. After prompt investigation of other secondary causes, it was determined that her stroke was likely secondary to her iron deficiency anemia. Upon review of the literature, a few case reports showed an association between iron deficiency anemia and strokes in the adult population, but little evidence exists supporting a direct relationship between the two entities. In this case, we aim to evaluate the complex relationship between iron deficiency anemia and stroke and to define a new potential cause of ischemic stroke, which would have been considered earlier as cryptogenic. However, further studies in the future are warranted to validate our observation.
ABSTRACT
Coronavirus disease 2019 (COVID-19) is a respiratory illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that was identified in December 2019. The impact of COVID-19 virus on Acquired Immunodeficiency syndrome (AIDS) patients has been reported with variable outcome. We reported a patient that was immunosuppressed by AIDS disease and chemotherapy for cancer who contracted SARS-CoV-2 infection and had a mild disease. We did literature review for the cases published that had human immunodeficiency virus (HIV) infection and COVID-19 disease and analyzed the characteristics and outcomes of the reported cases. Our review yielded three case reports and four case series for patients with HIV infection and COVID-19 disease. The majority of patients had mild disease, and some had critical disease or death. Those who had severe disease usually had other comorbidities. The findings from the case reports and case series indicate that the risk of death or severe disease from COVID-19 in HIV positive patients was lower than observed in the general population, which may indicate a possible protective effect of uncontrolled HIV in preventing the complications associated with the massive inflammatory response.
ABSTRACT
OBJECTIVE: Although the standard treatment of infective endocarditis (IE) is antimicrobial therapy, surgical intervention is required in some cases. However, the optimal timing of surgery remains unclear. Hence, we conducted a population-based analysis using the National Inpatient Sample (NIS) database to assess the outcomes of early versus late surgery in patients with native valve IE. METHODS: We queried the NIS database for all hospitalized patients between 2006 and 2016 with a primary diagnosis of IE who had cardiac surgery. We stratified surgery as early ≤7 or late >7 days of admission. Multivariable logistic regression models were used to assess in-hospital mortality and postoperative complications. Length of stay (LOS) and total hospital cost (HC) were evaluated using multivariable log-normal regression models. RESULTS: A total of 13 056 patients (57.6% in the early group and 42.4% in the late group) were included. The in-hospital mortality rate in the early group was 5.0% compared to 5.4% in the late intervention group (adjusted odds ratio, 1.20, 95% confidence interval [CI] 0.79-1.81). Overall median LOS was reduced in the early group by 48.2% (95% CI, 46.5%-49.9%, 12.4 days in the early group and 25.9 days in late group), as well as HC which was reduced in the early group by 28.3% (95% CI, 26.0%-30.6%). CONCLUSION: Among patients with native valve IE who needed cardiac surgery, the time of surgical intervention did not affect the in-hospital mortality. However, early surgery was associated with significantly shorter LOS and lower HC.

Myxedema coma occurs mostly in patients with long-standing untreated or undertreated hypothyroidism. Bradycardia is a well-known cardiac manifestation for myxedema coma; however, not all bradycardia with hypothyroidism are sinus bradycardia. Sick sinus syndrome is a group of arrhythmias caused by the malfunction of the natural pacemaker of the heart. Tachy-Brady syndrome is considered to be a type of sick sinus syndrome, where the heart alternates between tachycardia and bradycardia, and it is usually treated with pacemaker implantation along with rate slowing medical therapy. Here we report a case of an 83-year-old female who presented with myxedema coma and atrial fibrillation with tachycardia and intermittent slow ventricular response. We attempt to review the relationship between these two diseases and conclude that appropriate diagnosis of myxedema coma, may be beneficial in reducing the need for pacemaker implantation.

BACKGROUND: There is limited data on the efficacy of direct oral anticoagulants (DOACs) for the treatment of left ventricular thrombus. Currently, vitamin K antagonists (VKAs) remain the preferred oral anticoagulant for left ventricular thrombus. In this retrospective study, we assessed the safety and efficacy of DOACs in comparison to VKAs in patients with a new diagnosis of left ventricular thrombus. METHODS: We retrospectively identified all patients admitted to the 5 Catholic Health Initiative Omaha hospitals with a diagnosis of left ventricular thrombus between January 2012 and March 2019 and were discharged on oral anticoagulants. Patients were stratified into 2 groups: VKAs or DOACs and followed for up to 1 year. We compared the outcomes of ischemic stroke, bleeding, and echocardiographic resolution of left ventricular thrombus between the 2 groups. RESULTS: A total of 99 patients were included in this study (mean age: 61 years, 29% females). Of these, 80 (81%) were discharged on VKAs and 19 (19%) on DOACs. Stroke within 1 year of diagnosis occurred in 2 patients in the VKA group and none in the DOAC group (P = 0.49). Bleeding events were observed in 5 patients (4 in the VKA group and 1 in the DOAC group; P = 0.96). Ninety patients had follow-up echocardiogram; resolution of left ventricular thrombus was similar between the 2 groups (VKAs vs DOACs: 81% vs 80%; P = 0.9). CONCLUSION: In patients with left ventricular thrombus, DOACs and VKAs had similar rates of stroke and bleeding. These findings need confirmation in randomized clinical trials.

Critically ill patients are known to have a variety of electrolyte abnormalities. Lactic acidosis can frequently be seen secondary to shock states and is usually treated with aggressive volume resuscitation. Interestingly, hypophosphatemia is a potential cause of resistant lactic acidosis, which may not be as commonly identified or considered. We present a case of a 42-year-old man admitted twice over a span of 6 months with an elevated lactate level that did not resolve with volume resuscitation. It was ultimately determined that his lactic acidosis was due to hypophosphatemia after ruling out other potential causes. Phosphate replacement therapy resulted in the normalization of his lactate. In the literature, multiple theories have indicated the association of hypophosphatemia with lactic acidosis though no prior cases exist supporting a direct relationship. In this case, we set forth to evaluate the complicated relationship between all of these factors and to highlight the importance of early detection and treatment of hypophosphatemia, which may be beneficial in treating lactic acidosis.

Nonbacterial thrombotic endocarditis (NBTE) is illustrated by thrombi deposition on normal heart valves without the presence of bacteremia. It typically occurs in the setting of chronic debilitating diseases such as cancer or autoimmune disease. The pathogenesis involves an endothelial injury in the presence of a hypercoagulable state secondary to the effects of circulatory cytokines, which triggers platelet deposition. It usually forms on the upstream atrial surface of the mitral and tricuspid valves and the ventricular surface of the pulmonic and aortic valves and occurs most commonly in the fourth to eighth decades of life with no specific gender predisposition. These vegetations have a distinct morphology that varies from infective endocarditis (IE). Cerebrovascular lesions due to NBTE have a distinctive pattern of multiple, widely distributed small and large strokes on brain magnetic resonance imaging (MRI). We present a case of a 78-year-old man who was initially diagnosed as pneumonia and IE; he underwent a trans-esophageal echocardiogram (TEE), which revealed Libman-Sacks findings that have changed his diagnosis to lung cancer. We aim to highlight the characteristic TEE findings of NBTE to help clinicians search for underlying etiologies, including malignancies if NBTE is suspected.
ABSTRACT
Objective: To examine the effect of age on procedural and clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) lesions. Methods: Literature search was conducted across PubMed, Google Scholar and Web of science, databases till March 2019. Results: Seven studies including 7671 patients with an overall follow-up period of 1.5 to 5 years were included in our review. A total of 6299/1372 patients were included in non-elderly and elderly groups, respectively, with mean age and 67%/61% male patients. CTO-PCI was similarly successful in younger and older patients (82.8%, n = 5070 vs. 78.1%, n = 1010). The incidence of short-term outcomes was low across the studies and comparable between the two groups (all-cause mortality: 0.4% younger vs. 0.85% elderly, cerebrovascular accidents: 0.3% vs. 0.4%, major adverse cardiovascular events (MACE): 1.53% vs. 3.72% and major bleeding: 0.57% vs. 2.18%). Long-term outcomes including all-cause mortality (8.89% vs. 29.5%), cardiac mortality (3.72% vs. 15%) and MACE (24.9% vs. 40%) occurred with a higher incidence in elderly patients. When results were segregated according to the success of CTO-PCI, reduced clinical events were noted with successful revascularization in either age group. Conclusion: Compared with the younger age group, CTO-PCI in elderly patients is safe and feasible with a comparable incidence of short-term outcomes. In either population, the incidence of long-term outcomes including survival remains a concern but when successful, CTO-PCI may be associated with improvement in terms of multiple patient-important clinical end-points.
ABSTRACT
Hypolipidemia, an increasingly diagnosed disorder, is defined as a low-density lipoprotein serum level of <50 mg/dL. Hypolipidemia can be asymptomatic. However, the effect of hypolipidemia on sepsis survival and severity is still to be identified. Multiple studies show the physiologic effects of cholesterol on the immune system, and other studies linked hypolipidemia to increased mortality and morbidity. In this case, we present a young patient admitted for severe sepsis, and he developed multiorgan failure. Workup revealed hypolipidemia. The patient recovered from sepsis with residual renal and cardiac injury. We hypothesized that hypolipidemia could be contributing to the increased morbidity in the patient, although further studies are needed to approve this hypothesis. What is unique about this case is that it sheds light on a commonly overlooked metabolic abnormality that plays a role in the body's response to infections and sepsis. RELEVANCE FOR PATIENTS: This case report presents a previously healthy young patient admitted for pneumonia who had a complicated course. Workup revealed hypolipidemia that can be contributing to the severity of his disease. This observation may lead to more studies to evaluate the relationship between lipoprotein level and disease severity which may change the management for patients with hypolipidemia, especially with the familial type.
ABSTRACT
Rheumatoid vasculitis (RV) occurs in patients with long-standing rheumatoid arthritis (RA) or high levels of immunological factors and can result in devastating cardiovascular (CV) events. Here we report a case of a 38-year-old male who presented with hypertensive emergency and intracerebral hemorrhage (ICH). In the literature, a few observational studies have indicated the association of RA with hypertension; however, little evidence exists supporting a direct relationship between RA and ICH. In this case, we attempted to evaluate the complex relationship between all of these factors and found that early detection and treatment of RA may be beneficial in reducing ICH; however, large studies in the future are warranted to validate our observation.
