Strain Echocardiography During Septic Shock : an Observational Pilot Study

The mortality of septic shock remains high nowadays despite a trend toward improvement.Septic cardiomyopathy has been reported in most experimental models of sepsis shock. Its relationship with mortality is unclear. A decrease in mortality have been reported in patients with decreased left ventricular ejection fraction (LVEF), but a recent meta-analysis did not support such results. In fact, it appears that high LVEF are linked to profound vasoplegia which is associated to bad ...

The purpose of this study is to compare the diagnostic value of SENC to that provided by conventional wall motion analysis for the detection of inducible ischemia during DS-MRI.High-dose dobutamine stress magnetic resonance imaging (DS-MRI) is safe and feasible for the diagnosis of coronary artery disease (CAD) in humans. However, the assessment of cine scans relies on the visual interpretation of regional wall motion, which is subjective. Recently, Strain-Encoded MRI (SENC) ha...

Comparison of Two Methods of Strain by Perioperative Transesophageal Echo in CABG : An Observational Study

There is an increasing need for diagnostic modalities able to objectively quantify myocardial function. Quantification of regional myocardial function with ultrasound is challenging on its own.

Quantitative Assessment of RV Strain Using cMRI Following Catheter Intervention on PE

Acute pulmonary embolism (PE) is a condition in which the vessels carrying blood to the lungs become suddenly blocked, usually by a blood clot. There are a number of adverse consequences that result, with one of the most significant being strain on the right side of the heart (which must push blood through the blocked arteries to the lungs). Although this strain on the right heart is very important, current methods for measuring it are flawed. The standard practice is to obtain...

The Use of Myocardial Deformation Imaging

Myocardial deformation imaging allows analysis of myocardial viability in ischemic left ventricular dysfunction.

The study will determine optimal dosing for future cardiac...

A Prospective Study of Breast Cancer Patients With Abnormal Strain Imaging

The Cardio-Oncology program at Northwestern offers care to cancer patients who develop cardiac toxicities from chemotherapy. Breast cancer patients with the tumor marker for HER2 necessitate treatment with anthracycline and/or trastuzumab and pertuzumab-based chemotherapies, which are known to cause cardiac toxicities. Breast cancer patients will undergo a "cardio-oncology echocardiogram" which incorporates advanced left ventricular assessment by utilizing deformation or strain...

Coronary artery disease is the leading cause of death in USA. Contemporary cardiac care has substantially reduced mortality and morbidity in patients with severe coronary artery disease. However, patients with mild to moderate coronary artery stenosis (

Cardiac Magnetic Resonance in Non Ischemic Cardiomyopathy

Cardiac magnetic resonance imaging has been established as a promising three dimensional imaging modality with the ability to assess cardiac morphology, ventricular function, perfusion, viability and imaging characteristics of the surrounding vasculature without ionizing radiation. The accurate treatment of patients with cardiac disorders has created the need for accurate and reproducible measurements of cardiac chamber volumes and function. Cardiac magnetic resonance has the a...

Effect of Etelcalcetide on Cardiac Hypertrophy in Hemodialysis Patients

Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated.

A New Ultrasonographic Tool to Assess Pulmonary Strain in Patients Under One-lung Ventilation.

Mechanical ventilation is frequently used in the operating room and the intensive care settings. Although essential in many cases, mechanical ventilation can be responsible for ventilator-induced lung injury (VILI). The relationship between mechanical ventilation and VILI has been clearly demonstrated in animals and is highly suspected in humans. The putative mechanism responsible for VILI is excessive pulmonary strain or overdistension. Frequently observed in mechanically vent...
