ST elevation (STE) on the electrocardiogram (ECG) may be due to acute myocardial infarction (AMI) or other nonischemic pathologies such as left ventricular aneurysm (LVA). The objective of this study was to validate 2 previously derived ECG rules to distinguish AMI from LVA. The first rule states that if the sum of T-wave amplitudes in leads V1 to V4 divided by the sum of QRS amplitudes in leads V1 to V4 is greater than 0.22, then acute ST-segment elevation MI is predicted. The second rule states that if any 1 lead (V1-V4) has a T-wave amplitude to QRS amplitude ratio greater than or equal to 0.36, then acute ST-segment elevation MI is predicted.

Pulmonary atresia with intact ventricular septum and congenital left ventricular aneurysms are both rare, representing <1 and <0.1% of CHD, respectively. The association of left ventricular aneurysms and pulmonary atresia with intact ventricular septum has been documented in the literature, but all the previous case reports have involved children with acquired left ventricular aneurysms. We report an interesting case of a child with both pulmonary atresia with intact ventricular septum and a congenital left ventricular aneurysm. The combination of these two lesions ultimately affected the course of clinical care for the patient.

An institutional review board-approved retrospective review of 55 patients who received cardiac MRI within 1 year of myocardial SPECT was performed. Forty-nine demonstrated myocardial infarction by MRI. MRI and SPECT agreed in all but 1 case, where SPECT preceded MRI by 97 days. Three cases are presented here: 2 demonstrating congruent MRI and SPECT changes in a vascular distribution status post infarction and a third with a nonvascular pattern of abnormalities related to left ventricular aneurysm in cardiac sarcoidosis. It is useful to review and correlate myocardial SPECT with available cardiac MRI, especially in patients with matching perfusion defects.

Left ventricular thrombi usually occur in the setting of an acute myocardial infarction, left ventricular aneurysm, or dilated cardiomyopathy. In the absence of ventricular wall motion abnormalities, they are rare. We report the case of a patient with ulcerative colitis in whom two-dimensional echocardiography revealed a left intraventricular mass. Thrombosis in ulcerative colitis is a serious condition and can occur in a very young population. This case report also shows that left ventricular thrombi can occur in the active setting of ulcerative colitis.

Three-dimensional transthoracic echocardiography (3DTTE) may have a role in predicting final left ventricular volumes and clinical response after the surgical ventricular reconstruction (SVR) of left ventricular aneurysms and pseudoaneurysms. Left ventricle final volumes can be calculated through “virtual aneurysmectomy.” We present a patient with a huge ventricular dilation combined with myocardial dissection, localized wall rupture, and aneurysm of the left ventricular apex after acute myocardial infarction in which accurate predictions from 3DTTE suggest potential clinical value.

Congenital left ventricular aneurysm (CLVA) associated with multiple aneurysms with rupture into the left atrium (LA) is rare. We report a 17-year-old male with two CLVAs, one of which ruptured into the LA, and discuss the surgical management and review the literature of this rare disease.

Involvement of the mitral valve (MV) apparatus represents a challenge in surgical ventricular repair (SVR) of posterior left ventricular (LV) aneurysms. This study sought to investigate whether multislice computed tomography (MSCT) assessment can be used to optimize the surgical procedure for posterior LV aneurysms.

Progressive dyspnea after myocardial infarction can suggests the presence of left ventricular (LV) dysfunction or a left ventricular aneurysm (LVA). Surgical treatment of LVA aims to reduce its volume and to restore the ventricle. Recurrence of LVA after previous repair is extremely rare and the occurrence of concomitant postoperative true and false aneurysms is extraordinary. Surgery is usually challenging because of LV dysfunction and cardiac adherences in reoperations. We describe the simultaneous occurrence in a patient of a recurrent true and false LVA after surgical repair of a postinfarction LVA. Five years postoperatively, the patient remains alive and healthy.

Congenital left ventricular aneurysm (LVA) or diverticulum (LVD) is rare cardiac anomalies. We aimed to analyse the clinical characteristics and outcome in all ever published patients.
