Mri scar mortality

PURPOSE: Atrial fibrillation (AF) is the most common heart rhythm disorder and causes considerable morbidity and mortality, resulting in a large public health burden that is increasing as the population ages. It is associated with atrial fibrosis, the amount and distribution of which can be used to stratify patients and to guide subsequent electrophysiology ablation treatment. Atrial fibrosis may be assessed noninvasively using late gadolinium-enhanced (LGE) magnetic resonance imaging (MRI) where scar tissue is visualized as a region of signal enhancement...

Caesarean scar ectopic is one of the rarest of all ectopic pregnancies. It is defined as when a blastocyst implants on a previous Caesarean scar. The incidence of Caesarean scar ectopic has increased due to increase in number of Caesarean deliveries. Early diagnosis of this can be done by using sonography. It is very important because a delay can lead to increased maternal morbidity and mortality. Early diagnosis leads to prompt management and improves the outcome by allowing preservation of future fertility...

BACKGROUND: Pelvimetry assesses the size of a woman's pelvis aiming to predict whether she will be able to give birth vaginally or not. This can be done by clinical examination, or by conventional X-rays, computerised tomography (CT) scanning, or magnetic resonance imaging (MRI). OBJECTIVES: To assess the effects of pelvimetry (performed antenatally or intrapartum) on the method of birth, on perinatal mortality and morbidity, and on maternal morbidity. This review concentrates exclusively on women whose fetuses have a cephalic presentation...

Abstract/ Resumo Behcet's disease (BD) is a multisystem inflammatory disorder characterized by recurrent oral and genital ulcers, skin lesions and uveitis. The nervous system involvement of BD, neuro-Behcet's disease (NBD), is one of the important causes of mortality of the disease. Herein, we present a 29-year-old male with parenchymal NBD who has progressed rapidly and was managed with an uncommon aggressive immunosuppresive combination therapy. The patient first presented six years ago with vertigo and difficulty in talking and walking...

BACKGROUND: Decreased right ventricular (RV) ejection fraction (RVEF) portends poor prognosis in patients with ischemic cardiomyopathy, and previous studies have suggested an association between mitral regurgitation (MR) and RVEF. We sought to evaluate this association and whether mitral valve repair or replacement affects the relationship between RV function and mortality. METHODS: We included 588 patients (mean age, 63±11 years; 75% male) with ischemic cardiomyopathy who underwent cardiac magnetic resonance imaging between 2002 and 2008...

Introduction. Cesarean scar pregnancies (CSPs) are one of the rarest forms of ectopic pregnancy. Given their rarity, there is lack of consensus regarding the management and natural course of CSPs. Case. A 37-year-old G10 P3063 female with a history of two prior cesarean deliveries was diagnosed with her second CSP at 6 weeks and 5 days in her tenth pregnancy. The patient underwent vertical hysterotomy, excision of a gestational sac implanted in the cesarean sac, and bilateral salpingectomy via a laparotomy incision...

OBJECTIVE: Intraoperative overestimation of resection volume in epilepsy surgery is a well-known problem that can lead to an unfavorable seizure outcome. Intraoperative MRI (iMRI) combined with neuronavigation may help surgeons avoid this pitfall and facilitate visualization and targeting of sometimes ill-defined heterogeneous lesions or epileptogenic zones and may increase the number of complete resections and improve seizure outcome. METHODS: To investigate this hypothesis, the authors conducted a retrospective clinical study of consecutive surgical procedures performed during a 10-year period for epilepsy in which they used neuronavigation combined with iMRI and functional imaging (functional MRI for speech and motor areas; diffusion tensor imaging for pyramidal, speech, and visual tracts; and magnetoencephalography and electrocorticography for spike detection)...

BACKGROUND: The purpose of the study was to determine the long-term prognostic value of normal adenosine stress cardiac magnetic resonance imaging (CMR) in patients referred for evaluation of myocardial ischemia. METHODS: We reviewed 300 consecutive patients (age 65 ± 11 years, 74% male) with suspected or known coronary disease and normal wall motion who had undergone adenosine stress CMR negative for ischemia and scar. Most patients were at intermediate risk of coronary artery disease...

BACKGROUND: The presence of myocardial scar detected by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging has been described as a good independent predictor of mortality in patients with hypertrophic cardiomyopathy (HCM). Time-domain T-wave alternans (TWA) is also a potential predictor of cardiac mortality in patients with left ventricular dysfunction. OBJECTIVE: The purpose of this study was to elucidate the relationship between LGE distribution and TWA in patients with HCM...

BACKGROUND: Left ventricular thrombus (LVT) formation occasionally complicates patient recovery post myocardial infarction, conveying a significant risk of systemic embolism. Accordingly, thrombus detection and subsequent anticoagulation is imperative in order to minimize patient morbidity and mortality. Transthoracic echocardiography (TTE) is the imaging modality most widely used to screen for thrombus formation despite its suboptimal sensitivity and specificity. CASE PRESENTATION: This report describes the discordant imaging findings of a LVT in a 56 year old Caucasian male with an anterior ST elevation myocardial infarction...

BACKGROUND: Ventricular tachycardia (VT), a common manifestation of cardiac sarcoidosis (CS), is associated with high morbidity and mortality. It could be mistaken for idiopathic VT (IVT) in the absence of systemic manifestations and overt cardiac structural abnormality. We studied the electrocardiogram (ECG) characteristics of VT in CS that may distinguish from IVT and also explored the relationship of the ECG characteristics with imaging findings in patients with CS. METHODS AND RESULTS: Twelve-lead ECG characteristics of VT in CS patients (Group I = 37) were compared with IVT (Group II = 49)...

OBJECTIVES: We hypothesized that myocardial scar characterization using cardiac magnetic resonance imaging (CMR) may be associated with the occurrence of ventricular tachyarrhythmia (VT), appropriate implantable cardioverter-defibrillator (ICD) therapy and mortality. BACKGROUND: Since a minority of patients with prophylactic ICD implantation receive appropriate ICD therapy, there is a need for more effective risk stratification for primary prevention in patients with ischemic cardiomyopathy...

OBJECTIVE: To assess the effectiveness of grey-scale and colour Doppler ultrasound (US) versus magnetic resonance imaging (MRI) for the prenatal diagnosis of placenta accreta. METHODS: A prospective observational study including a total of 74 patients with placenta previa and previous uterine scar (n = 74). Grey-scale and colour Doppler US was done followed by MRI by different observers to diagnose adherent placenta. Test validity of US and MRI were calculated...

Heart failure presents a significant problem in industrialized countries, with a high prevalence, morbidity, and mortality, where it is most frequently caused by coronary artery disease. Revascularization in patients with symptomatic heart failure has been associated with improved cardiovascular outcomes. Predictors of outcome benefit from revascularization include the presence and extent of hibernating myocardium, ischemia, scar, left ventricular ejection fraction, and renal function. Viability is useful in directing the management of patients with ischemic cardiomyopathy...

BACKGROUND: Infarct heterogeneity has been shown to be independently associated with adverse outcomes in previous smaller studies. However, it is unknown whether infarct characterization is an independent predictor of all-cause mortality in patients with advanced ischemic cardiomyopathy, after adjusting for clinical risk factors, severity of ischemic mitral regurgitation, incomplete revascularization, and device therapy. METHODS AND RESULTS: A total of 362 patients with ischemic cardiomyopathy (left ventricular dysfunction with >70% stenosis in ≥1 epicardial coronary artery) underwent delayed hyperenhancement-magnetic resonance imaging and coronary angiography between 2002 and 2006...

UNLABELLED: Cardiac magnetic resonance (CMR) identifies important prognostic variables in ischemic cardiomyopathy (ICM) patients such as left ventricular (LV) volumes, LV ejection fraction (LVEF), peri-infarct zone, and myocardial scar burden (MSB). It is unknown whether Doppler-based diastolic dysfunction (DDF) retains its prognostic value in ICM patients, in the context of current imaging, medical, and device therapies. METHODS: Diastolic function was evaluated in ICM patients (LVEF ≤ 40% and ≥ 70% stenosis in ≥ 1 coronary artery) who underwent transthoracic echocardiogram and delayed hyperenhancement CMR studies within 7 days...

Postpartum and posttermination complications are common causes of morbidity and mortality in women of reproductive age. These complications can be broadly categorized into vascular, infectious, surgical, and neoplastic etiologies, or are due to ectopic implantation of placental or endometrial tissue. Causes of postpartum vascular complications include retained products of conception, arteriovenous malformation, and pseudoaneurysm. Infectious entities include endometritis, abscess, wound cellulitis, and pelvic septic thrombophlebitis...

Despite significant advancements in the treatment of ischemic heart disease (IHD), IHD remains a leading cause of mortality and morbidity. In addition, there remains clinical equipoise regarding a number of important management issues across the spectrum of IHD, from evaluating patients with chest pain in the emergency department, to deciding whether patients with chronic stable angina or severe ischemic cardiomyopathies should undergo invasive revascularization procedures. Recent data over the past 2 decades has demonstrated that cardiac magnetic resonance imaging is highly accurate and carries robust prognostic value in the evaluation of patients with both acute and chronic IHD...
