Left Ventricular Performance Following Direct Myocardial Revascularization

Editorial: Left ventricular performance following direct myocardial revascularization.

Regional left ventricular performance in the year following myocardial infarction.

The relationship of abnormal regional myocardial performance to left ventricular (LV) function 2-12 months following transmural myocardial infarctfon was investigated in 25 patients by quantitative biplane angiocardiography. Abnormally contracting segments (ACS) (akinetic or dyskinetic) of the LV were identified in 24 patients. Their sites correlated with the electrocardiographic locations of i...

Ventricular Arrhythmias and Myocardial Revascularization

Ventricular arrhythmias are closely associated with myocardial ischemia and its sequelae. Acute ischemia frequently leads to ventricular fibrillation (Vfib) and to sudden cardiac death. As well, chronic ischemia, if presented as ischemic cardiomyopathy with restricted left ventricular function, is prone to the risk of Vfib. In contrast, scar formation after myocardial infarction leads to reentr...

Influence of Direct Myocardial Revascularization on Left Ventricular Asynergy and Function in Patients with Coronary Heart Disease

asynergy was present preoperatively in 12 of the 18 patients in the first two groups. Marked improvement occurred in all and a normal wall motion was restored in the majority following surgery. More pronounced improvement was noted in the preinfarction syndrome as compared to the group with chronic ischemia and no previous infarct. The ejection fraction was reduced in 12 of the 18 patients in t...

Unruptured left ventricular pseudoaneurysm following inferior wall myocardial infarction.

Left ventricular (LV) pseudoaneurysm is a rare but potentially lethal complication of acute myocardial infarction (MI). We report a very rare case of a 60 year-old woman with a ruptured myocardial wall, and a non-ruptured LV pseudoaneurysm. The patient presented with acutely worsening shortness of breath and exertional dyspnea of one month's duration, and palpitation. She had an inferior wall M...
