Simulation of left ventricular function during dyskinetic or akinetic aneurysm

Simulation of left ventricular function during dyskinetic or akinetic aneurysm.

The purpose of our study was to simulate the hemodynamics of left ventricular function after left ventricular aneurysm (LVA) of various sizes and to validate the results of this computer based simulation with patient data. We developed an equivalent electronic circuit (EEC) that reflects the hemodynamic conditions of LVA (after acute myocardial infraction) while taking into consideration the re...

Massive left ventricular aneurysm or unruptured pseudoaneurysm?

Unruptured Pseudoaneurysm? To the Editor: The Image in Cardiovascular Medicine by Stehlik and colleagues1 is not completely accurate with regard to the diagnosis of left ventricular aneurysm and the related terminology. The authors said that left heart catheterization demonstrated and transesophageal echocardiogram confirmed the diagnosis of left ventricular aneurysm. However, these findings we...

Left ventricular function during pregnancy.

As emphasized by Watkins et al.,9 the variability in plasma renin activity in CHF is explained by the degree of compensation in maintaining arterial pressure and plasma volume; the latter measurement was not obtained in the Curtiss or Gavras study. The observations in these two recent studies reaffirm the importance of the RAA system in maintaining systemic vascular resistance (SVR) in CHF. Cur...

Left ventricular aneurysm.

Left ventricular septal aneurysm.

A6-month-old girl (3.5 months corrected, born at 28 weeks gestational age) presented with a history of increasing tachypnea, diaphoresis, difficulty feeding, and poor weight gain. A 15-lead ECG done on day 41 of life had revealed normal sinus rhythm with a nonspecific intraventricular conduction delay. At that time, clinically there was a soft systolic murmur and no evidence of congestive heart...
