ABSTRACT

Coronavirus Disease 2019 (COVID-19) has been a significant cause of global mortality and morbidity since it was first reported in December 2019 in Wuhan, China. COVID19 like previous coronaviruses primarily affects the lungs causing pneumonia, interstitial pneumonitis, and severe acute respiratory distress syndrome (ARDS). However, there is increasing evidence linking COVID-19 to cardiovascular complications such as arrhythmias, heart failure, cardiogenic shock, fulminant myocarditis, and cardiac death. Given the novelty of this virus, there is paucity of data on some cardiovascular complications of COVID-19, specifically myocarditis. Myocarditis is an inflammatory disease of the heart muscle with a heterogenous clinical presentation and progression. It is mostly caused by viral infections and is the result of interaction of the virus and the host's immune system. There have been several case reports linking COVID-19 with myocarditis, however the true mechanism of cardiac injury remains under investigation. In this paper we review the clinical presentation, proposed pathophysiology, differential diagnoses and management of myocarditis in COVID-19 patients.

ABSTRACT

Recent trials have shown impressive results in low-risk patients undergoing Transcatheter Aortic Valve Replacement (TAVR) with low procedural complication rates, short hospital length of stay, zero mortality, and zero disabling stroke at 30 days and have led to a Food and Drug Administration indication for TAVR in these patients. The long-term data on subclinical leaflet thrombosis, valve durability, effects of pacemaker implantation, right ventricular pacing, and progressive paravalvular leak is unclear. We describe clinical and procedural considerations for patient selection and introduce future potential procedural challenges. Finally, we discuss the importance of considering life expectancy and durability prior to TAVR in this low risk relatively young cohort and emphasize the importance of a heart team approach.

ABSTRACT

One of the major issues in management of the acute coronary syndrome (ACS) is classification of patients with atypical presentation who have low risk of having a coronary episode at presentation. There have been multiple studies on the stratification of high risk patients and medical management of such cases, however, there is a sub-class of patients who do not fit any category. In this paper, we have looked at the current literature on stratification of patients based on the study tools available and the risk of having a coronary episode during the following year. In our overview, we have found that the current methods in place namely, cardiac stress test and stress echocardiogram have a good prognostic factor in terms of mortality in the next one year and can safely stratify the patients at low risk when correlated with clinical presentation and laboratory studies. However, such data are limited for computerized tomography or magnetic resonant imaging and their application might be limited due to accessibility and cost of studies. Current guidelines for classification of high risk patient do an excellent job and we believe that proper application of stress tests together with other imaging modalities together with laboratory, clinical judgment, and proper use of medical management can help with safe discharge of patients from the emergency department (ED) and reduction of burden from healthcare.

ABSTRACT

BACKGROUND: There has been much debate on whom to screen, how to screen, and how to treat blunt cerebrovascular injury (BCVI), but there has been little published on long-term functional outcomes following diagnosis and treatment of BCVI. This study was conducted to address those long-term outcomes. METHODS: Patients with BCVI during a 53-month period ending June 2009 were identified. Charts were reviewed for demographics, associated injuries, treatments, strokes, and in-hospital mortality. Posthospital discharge follow-up was conducted. A structured telephone interview was performed using a functional independence measurement-functional activity measurement questionnaire consisting of 30 questions in seven categories (self-care, sphincter control, mobility, locomotion, communication, psychosocial, and cognitive). Each question was scored from 1 (requires full assistance) to 7 (fully independent). Outcomes were compared by type of BCVI, associated injuries, and stroke. RESULTS: Two hundred twenty-two patients with BCVI were identified. Twenty-four patients died during their initial hospitalization, and an additional 11 patient died after hospital discharge. The 68 patients who completed the interview constituted our study population. Mean follow-up was 35 months. Of a possible 210 points, the mean total score on functional independence measurement and functional activity measurement was 186, 185, and 188 for all patients, carotid artery injuries, and vertebral arteries injuries, respectively. A significant difference was seen when comparing patients with and without strokes (173 and 189, respectively). CONCLUSION: This is the first report of functional outcomes following BCVI. We found that carotid and vertebral artery injuries have similar functional outcomes. As would be expected, the development of stroke led to worse outcomes. This underscores the importance of early diagnosis and initiation of therapy. Prevention of stroke in patients with BCVI leads to near-normal functional outcomes. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level III.

ABSTRACT

BACKGROUND: Blunt cerebrovascular injuries (BCVI) once went unrecognized until cerebral ischemia or death occurred. We previously demonstrated that screening of high-risk asymptomatic patients and early treatment improved outcomes. However, major dissections, pseudoaneurysms, and fistulas rarely heal with antithrombotic therapy alone. Endovascular therapy in these lesions has increased without reports of outcomes. We sought to determine ischemic stroke and death rates after BCVI with and without endovascular treatment. STUDY DESIGN: Patients with BCVI during a 53-month period ending May 2009 were identified. Antithrombotic therapy with heparin (goal partial thromboplastin time 40-60 s) or antiplatelets (aspirin and/or clopidogrel) was instituted after diagnosis of BCVI. Endovascular treatment was performed in patients with pseudoaneurysms, major dissections, and fistulas, whereas minor dissections and occluded vessels were treated with medical therapy alone. Outcomes evaluated were ischemic stroke and mortality, both in hospital and long term. RESULTS: A total of 222 patients had 263 BCVI (115 carotid, 148 vertebral injuries); 22 patients had ischemic strokes before their angiographic diagnosis (17 present on arrival, 5 before angiography); 41% of patients underwent endovascular treatment for their BCVI, 50% were placed on heparin drips, and 76% and 52% were given aspirin and clopidogrel, respectively. Seven patients developed infarcts after BCVI diagnosis for a postdiagnosis rate of 4%. Follow-up was achieved in 85% of patients at a mean of 22 months. In-hospital mortality was 11%, and overall mortality rate was 16% at last follow-up. CONCLUSIONS: Endovascular therapy of appropriate lesions in conjunction with medical therapy leads to the lowest ischemic stroke rates reported. Despite being used for more severe lesions with higher potential for ischemia, endovascular therapy had outcomes similar to medical therapy. Aggressive screening and treatment of BCVI leads to the lowest reported mortality and stroke rates.
