Acute traumatic central cord syndrome: magnetic resonance imaging and clinical observations

In the setting of AMI, there are a number of causes of acuted shock, including reduction in LV function, RV infarction, acute severe mitral regurgitation and mechanical complications: Patients with ventricular arrhythmias require clarification of the aetiology of their arrhythmias for decision-making and ongoing care.

Patients with suspected pericardial disease, including effusion, constriction or effusiveconstrictive process; Pericardial friction rubs developing in acute myocardial infarction accompanied by symptoms such as persistent pain, hypotension, and nausea; Patients with suspected bleeding in the pericardial space i.

RV infarction is most often associated with inferior AMI but rarely may be an isolated condition. Apical and midventricular transient left ventricular dysfunction syndrome tako-tsubo cardiomyopathy: In patients presenting with acute dissection of the abdominal aorta, clinical symptoms i.

The echocardiographic examination with the current generation of pocket-size imaging devices does not allow performance of, nor replacement of, a complete echocardiogram 20 and their limitations must therefore be recognized.

The diagnosis primarily relies upon clinical history chest pain changing with inspiration and positionexamination pericardial friction rub; audible, however, in only one-third of patientsECG diffuse concave upwards ST segment elevation and PR segment depression and TTE features. Heart failure HF is the most common cardiac cause of acute dyspnoea, 50 which can be related to either new-onset HF or to worsening of i,ager HF. Right-sided valvular pathology rarely leads to decompensation acuuter the patient to the extent that admission is indicated per sebut the underlying pathology iamger.
