1232 Acute myocarditis: prognostic role of speckle tracking echocardiography and cardiac magnetic resonance

2020

Abstract Background Myocarditis is an inflammatory disease of the myocardium predominantly caused by infection with subsequent immunological response. Cardiac magnetic resonance (CMR) is the currently best imaging modality to confirm a suspected diagnosis of myocarditis. Conventional echocardiography can detect regional or global wall motion abnormalities but it could also be negative. Speckle tracking echocardiography can help to identify subtle systolic dysfunction, in patients with myocardits and apparently negative echocardiogram. Purpose the aim of this study was to identify cardiac imaging parameters predictive of cardiovascular events in patients with acute myocarditis. Methods a pro…

Takotsubo cardiomyopathy features at cardiac magnetic resonance

2012

Abstract Diagnosis of Takotsubo cardiomyopathy is based on clinical symptoms, electrocardiographic changes, absence of angiographic significant coronary lesions and presence of suggestive wall motion abnormalities. CardioMRI is an useful complementary tool especially to role out the diagnosis of myocarditis and of myocardial infarction with angiographically normal coronary artery and to document complications of the disease.

Juvenile Rheumatoid Arthritis and Still’s Disease

1975

In the Anglo-American literature, the term “Still’s disease”, based on the observations of ○Cornil (1864) and Still (1897) is generally employed to cover the juvenile forms of rheumatoid arthritis, defined by Ansell and Bywaters (1959). German paediatricians, on the other hand, particularly Storber and Kolle, regard Still’s disease as a separate syndrome. Kolle uses the following characteristics for this distinction: 1. High fever at the commencement of illness. 2. Enlargement of lymph nodes, spleen and liver. 3. Myocarditis and pericarditis. 4. High leucocyte count. 5. Erythema multiforme in about 70% of patients.

Cardiac magnetic resonance in the diagnosis of the unusually detected acute myocarditis in the young people: a case report

2021

Myocarditis is among the causes of arrhythmic sudden cardiac death (SCD) in young athletes, with viral infection being the most common cause worldwide. Myocarditis recently has been reported as one of the cardiac complications of coronavirus disease 2019 (COVID-19) in athletes. Here we present a case of a 20-year-old male recreational soccer player with an episode of loss of consciousness in the context of respiratory infection. The patient reports having woken up with symptoms of an upper respiratory tract infection, and after playing a soccer match, he developed dizziness and a headache. He then suffered vasovagal syncope without loss of sphincter control. Physical examination, heart ausc…

Phrenic nerve displacement by intrapericardial balloon inflation during epicardial ablation of ventricular tachycardia: Four case reports

2020

BACKGROUND Phrenic nerve (PN) injury is one of the recognized possible complications following epicardial ablation of ventricular tachycardia (VT). High-output pacing is a widely used maneuver to establish a relationship between the PN and the ablation catheter tip. An absence of PN capture is usually considered an indication that it is safe to ablate, and that successful ablation may be performed at adjacent sites. However, PN capture may impact the procedural outcome. Only a few cases have been reported in the literature that avoid PN injury by using different techniques. CASE SUMMARY Three patients with a previous history of myocarditis and one patient with ischemic cardiomyopathy underw…

Oncolytic targeting of renal cell carcinoma via encephalomyocarditis virus

2010

Apoptosis is a fundamental host defence mechanism against invading microbes. Inactivation of NF-kappaB attenuates encephalomyocarditis virus (EMCV) virulence by triggering rapid apoptosis of infected cells, thereby pre-emptively limiting viral replication. Recent evidence has shown that hypoxia-inducible factor (HIF) increases NF-kappaB-mediated anti-apoptotic response in clear-cell renal cell carcinoma (CCRCC) that commonly exhibit hyperactivation of HIF due to the loss of its principal negative regulator, von Hippel-Lindau (VHL) tumour suppressor protein. Here, we show that EMCV challenge induces a strong NF-kappaB-dependent gene expression profile concomitant with a lack of interferon-me…
