Septic pseudo-aneurysm of the left main trunk in a dialysis patient.

This case report relating the association between a septic pseudo-aneurysm of the left trunk and myocardial infarction underscores the importance of early non-invasive imaging when acute myocardial infarction is associated with frank clinical or biological signs of systemic sepsis.

Prognostic importance of tissue Doppler-derived diastolic function in patients presenting with acute coronary syndrome: a bedside echocardiographic study.

Aims: We sought to evaluate the prognostic value of bedside tissue Doppler derived diastolic function in patients presenting with acute coronary syndrome (ACS) on top of major clinical predictors of mortality and routine laboratory testings.

Methods And Results: Bedside Doppler echocardiography and laboratory tests were prospectively performed in 239 consecutive patients (mean age 62 +/- 14, 69% men) admitted for ACS. Ratio of early transmitral flow (E) to early mitral annulus velocities (e') was calculated.

Mid-ventricular ballooning heart syndrome.

Stress cardiomyopathies have been increasingly reported these last years, especially in women as a transient left ventricular apical ballooning syndrome. We report six cases in whom, in the context of anxious situations, echocardiograms and ventriculographies revealed mid-ventricular akinesis with preservation of apical and basal contractilities with normal coronary arteriography. This "mid-ventricular ballooning heart syndrome " should probably be classified as a new type of heart stress related syndrome.

Low-level exercise echocardiography fails to elicit left ventricular contractile reserve in patients with aortic stenosis, reduced ejection fraction, and low transvalvular gradient.

Background: Low-level exercise echocardiography is useful to assess left ventricular (LV) contractile reserve after an acute myocardial infarction. Whether low-level exercise can elicit LV contractile reserve in patients with severe aortic stenosis, reduced LV systolic function and low transvalvular gradient are unknown. Accordingly, the value of low-level exercise to elicit contractile reserve was assessed in these patients using dobutamine administration as the gold standard method.

Hemidiaphragmatic paralysis: an underestimated etiology of right-to-left shunt through patent foramen ovale?

Objective: To report a specific pathophysiology of hemidiaphragmatic paralysis that may result in severe hypoxemia.

Design: Case series.

Setting: Intensive care unit in a cardiology hospital.

Acute coronary syndromes associated with thrombus in the sinus of valsalva and normal coronary arteriography: the pivotal role of transesophageal echocardiography in the intensive care unit.

We describe 4 patients with thrombus in nonaneurysmal sinus of Valsalva. The diagnosis was made with transesophageal echocardiography performed in the Intensive care unit, in the setting of acute coronary syndromes. Coronary arterlography showed normal coronary arteries in each patient.

Transient left ventricular basal dysfunction without coronary stenosis in acute cerebral disorders: a novel heart syndrome (inverted Takotsubo).

Myocardial dysfunction without coronary involvement may occur in acute cerebral diseases. We report 4 cases where, in the context of acute cerebral disorder, the echocardiograms revealed an extensive left ventricular circumferential akinesis except at the apex. Besides, for three of those cases no coronary disease has been highlighted.
