Papillary muscle infarction in relation to left ventricular infarct distribution and transmurality - assessment by delayed enhancement cardiac magnetic resonance imaging

چکیده
Methods Patients with initial STEMI were enrolled in a prospective imaging registry. CMR (1.5T) was performed within 6 weeks (27±8 days) post-STEMI. Cine-CMR (SSFP) was used to assess LV wall motion (17 segment model, 5 point per-segment score) DE-CMR (IR-GRE, acquired 10-30 minutes post gadolinium [0.2 mmol/kg]) was used to assess infarct morphology: PMI was graded for location and extent (partial or complete, stratified by >50% papillary hyperenhancement); LV infarction was quantified based on global size and regional transmurality (17 segment, 5 point per-segment score). Invasive coronary angiograms were read blinded to CMR.

متن کاملPrediction of life-threatening arrhythmic events in patients with chronic myocardial infarction by contrast-enhanced CMR.
OBJECTIVES We hypothesized that infarct transmurality assessed with late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) predicts arrhythmic events in patients with chronic myocardial infarction. BACKGROUND Patients with decreased left ventricular function due to chronic myocardial infarction are at increased risk for life-threatening arrhythmias related to infarcted tissue. LGE-C...
متن کاملImaging Prevalence and Clinical Significance of Papillary Muscle Infarction Detected by Late Gadolinium-Enhanced Magnetic Resonance Imaging in Patients With ST-Segment Elevation Myocardial Infarction
Background—The frequency of papillary muscle infarction (PapMI) without rupture has not been fully investigated in vivo. Furthermore, the relationship between papillary muscle dysfunction and mitral regurgitation (MR) has been controversial in patients with ST-segment elevation myocardial infarction. Therefore, the aim of this study was to assess the frequency and clinical characteristics of Pa...

متن کاملInfarct transmurality and adjacent segmental function as determinants of wall thickening in revascularized chronic ischemic heart disease.
BACKGROUND There are many factors which influence regional left ventricular wall thickening (WT) in ischemic heart disease (IHD). We used magnetic resonance imaging (MRI) to explore, in patients with chronic ischemic heart disease (CIHD), how regional WT is affected by both infarct transmurality (IT) and the function of adjacent segments. We also compared these findings with a group of healthy ...
