Confirmation of Non-Ischemic Etiology of Left Ventricular Aneurysm

A case of left ventricular aneurysm of uncertain etiology presenting as ventricular tachycardia.

A case of a 59-year-old Asian male with several episodes of syncope and palpitation is reported. Electrophysiologic study disclosed that sustained ventricular tachycardia was induced by programmed electrical stimulation at the right ventricular apex. The electrogram in the left ventricular aneurysm showed delayed activities and the fastest depolarization. Entrainment was observed by faster paci...

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...

Left Ventricular Aneurysm

Angiocardiographic characteristics of the residual contracting left ventricle (LV) have been examined in 16 patients with anterolateral ventricular aneurysms (VA). In each patient a contractile section (CS) of the LV was clearly demarcated from the remaining aneurysmal section (AS). Using a double hemispheroid model, volumes of CS and AS were separately estimated by a modified area-length metho...

[Chronic left ventricular pseudoaneurism of undetermined etiology].

Pseudoaneurysms occur as a rare complication of the myocardial infarction, of which hemorrhagic process is contained by adherences of the visceral or parietal pericardium - or of both - preventing the development of cardiac tamponade. We report the case of a 55-year-old patient, with a chronic left ventricular pseudoaneurysm of undetermined etiology, who was submitted to a conservative treatment.
