Percutaneous coronary intervention for acute myocardial infarction with mitral regurgitation
Ischemic mitral regurgitation (IMR) is a common complication of acute myocardial infarction (AMI). Current evidences suggest that revascularization of the culprit vessels with percutaneous coronary artery intervention (PCI) or coronary artery bypass grafting can be beneficial for relieving IMR. A 2.5-year follow-up data of a 61-year-old male patient with ST-segment elevation AMI complicated wit...
متن کاملIschemic mitral regurgitation in patients with acute myocardial infarction.
AIM OF THE STUDY Echocardiographic evaluation of mitral regurgitation (MR) during the evolution of patients with acute myocardial infarction (MI). MATERIAL AND METHODS The study included 104 patients (73 males and 31 females), aged between 38-85, diagnosed with acute myocardial infarction (based on clinical, ECG and enzymatic evidences), in order to assess the MR (clinically--a new systolic m...
متن کاملLeft Ventricular Mechanics in Functional Ischemic Mitral Regurgitation in Acute Inferoposterior Myocardial Infarction
UNLABELLED Ischemic mitral regurgitation (MR) is an established adverse prognostic factor after myocardial infarction (MI). Functional ischemic mitral regurgitation in acute phase of MI remains under-investigated due to its often transient and dynamic nature. We aimed to assess left ventricular (LV) mechanics by speckle-tracking echocardiography in acute inferoposterior MI and ischemic mitral r...
متن کاملAcute Mitral Regurgitation in Man
Four patients are presented who developed acute mitral regurgitation 5 days, 2, 3, and 18 months, respectively, before cardiac catheterization. The hemodynamic findings in the three early cases resemble those found in the presence of a constricting pericardium: left and right ventricular, as well as left and right atrial pressures, equilibrated during diastole. As expected, giant left atrial v ...
متن کاملQuantitative echocardiography of the mitral complex in dilated cardiomyopathy: the mechanism of functional mitral regurgitation.
We sought to elucidate the mechanism of mitral regurgitation (MR) in dilated cardiomyopathy (DCM). Quantitative two-dimensional echocardiographic examinations were performed in 27 patients, 18 with DCM (nine with MR on physical examination, nine without MR) and nine without underlying heart disease. The MR and "no MR" patients were clinically comparable. Spatial reconstructions from multiple ap...
