The embolic storm: dramatic peripheral complications of left ventricular thrombosis after myocardial infarction.

Left ventricular thrombus is a common complication after acute myocardial infarction. Although anticoagulant treatment has an established role in reducing the rate of thrombus formation and embolic phenomena during acute myocardial infarction, prior studies showed that left ventricular thrombus and systemic embolization may develop irrespective of adequate anticoagulant therapy. We present a descriptive case of a patient with left ventricular thrombus who experienced dramatic peripheral embolic events soon after the onset of anterior myocardial infarction despite full anticoagulation, and we discuss possible pathogenesis.

Acute superior vena cava syndrome after insertion of implantable cardioverter defibrillator.

We describe a rare case of superior vena cava syndrome that occurred a few hours after insertion of an implantable cardioverter defibrillator through the right subclavian vein in a patient with previous dual chamber DDD pacemaker. The patient was successfully treated with anticoagulant therapy showing a fast clinical and instrumental improvement.

A case of Guillain-Barrè syndrome following Staphylococcus aureus endocarditis.

Guillain-Barrè syndrome (GBS) is the most important cause of acute neuromuscular paralysis in western countries and it is preceded in almost all cases by an infectious disease such as Campylobacter Jejuni or Cytomegalovirus. However, GBS associated with previous bacterial endocarditis is very rare. We report the case of a 74-year-old man with GBS following Staphylococcus Aureus endocarditis affecting aortic valve. Although the absolute incidence of GBS is low, the present case stresses the need to consider GBS in patients developing neurological symptoms following any infectious illness, such as endocarditis, and highlights the challenging problem of rehabilitation and surgical management in these patients.

[Echocardiographic features in a case of tuberculous lymphadenitis]. / L'ecocardiogramma in un caso di linfoadenite tubercolare.

Tuberculosis can secondarily affect the heart, mainly the pericardium and less frequently the endocardium and coronary vessels. Tuberculous myocarditis usually is a post-mortem diagnosis, and affects the right atrium and left ventricle presenting as miliary granulomas with or without caseating necrosis, or as diffuse cellular infiltration. We report the case of a 65-year-old man, affected by tuberculous lymphadenitis, with a history of hyperkinetic atrial and ventricular arrhythmias. Magnetic resonance, transthoracic and transesophageal echocardiography showed a peculiar cardiac involvement, characterized by right ventricular and left atrial infiltration. As the patient refused myocardial biopsy, the diagnosis of tuberculous myocarditis was stated ex-adjuvantibus, after specific multidrug chemotherapy with complete remission of all echocardiographic abnormalities. Echocardiography represents a useful diagnostic tool in patients presenting with clinical and electrocardiographic features, that even not specific could be suggestive of tuberculous myocarditis, whose incidence could be greater than reported in the literature.
