Comparison of the Hemodynamic Response to Intra-Aortic Balloon Counterpulsation in Patients With Cardiogenic Shock Resulting from Acute Myocardial Infarction Versus Acute Decompensated Heart Failure.

The intra-aortic balloon pump (IABP) neither benefits nor harms patients with acute myocardial infarction (AMI) with cardiogenic shock (CS) but may stabilize those with chronic heart failure who decompensate into CS. We sought to compare its hemodynamic effects in these 2 populations. We performed a retrospective analysis of the hemodynamic effects of IABP for AMI or acute decompensated heart failure (ADHF) patients with hemodynamic evidence of CS.

Left circumflex coronary artery to hepatic vein fistula: a case report and brief review of coronary vasculogenesis.

Coronary artery fistulas are rare coronary artery anomalies. Their clinical significance varies from a long asymptomatic course to overt heart failure and death. They are often detected incidentally with diagnostic coronary angiograms.
