Autologous transplantation of CD34⁺ bone marrow derived mononuclear cells in management of non-reconstructable critical lower limb ischemia

Ahmed M. Ismail, Said M. Abdou, Hassan Abdel Aty, Adel H. Kamhawy, więcej

Cytotechnology > 2016 > 68 > 4 > 771-781

Patients with a decrease in limb perfusion with a potential threat to limb viability manifested by ischemic rest pain, ischemic ulcers, and/or gangrene are considered to have critical limb ischemia (CLI). Because of this generally poor outcome, there is a strong need for attempting any procedure to save the affected limb. The aim of this work is to evaluate the possibility to use stem cell therapy...

Florian André, Astrid Burger, Dirk Loßnitzer, Sebastian J. Buss, więcej

International Journal of Cardiology > 2015 > 185 > Complete > 240-247

Since the differentiation between physiological and pathological trabeculation is challenging, we assessed its distribution in a reference population of selected healthy volunteers.We studied 117 subjects (58 males) stratified into age tertiles and by gender. Cardiovascular magnetic resonance images were acquired using a standard SSFP-sequence. Left and right ventricular (LV/RV) end-diastolic (EDV),...

Selective apheresis of C‐reactive protein: A new therapeutic option in myocardial infarction?

Ahmed Sheriff, Ralf Schindler, Birgit Vogt, Hassan Abdel‐Aty, więcej

Journal of Clinical Apheresis > 30 > 1 > 15 - 21

Background: There is substantial evidence that C‐reactive protein (CRP) mediates secondary damage of the myocardium after acute myocardial infarction (AMI). The aim of this animal trial in pigs was to specifically deplete CRP from porcine plasma after AMI and to study possible beneficial effects of the reduced CRP concentration on the infarcted area. Methods: Ten pigs received balloon catheter‐induced...

Clinical Research in Cardiology > 2014 > 103 > 6 > 441-450

Objectives To investigate whether cardiac magnetic resonance phase-contrast imaging (PC-CMR) can determine left ventricular (LV) diastolic function in comparison to echocardiography (EC). Background Non-invasive evaluation of diastolic function is important for the diagnostic classification and risk stratification of patients with cardiomyopathies. With EC, diastolic function is classified based...

Philipp Boyé, Hassan Abdel-Aty, Udo Zacharzowsky, Steffen Bohl, więcej

JACC: Cardiovascular Imaging > 2011 > 4 > 8 > 871-879

We hypothesized that infarct transmurality assessed with late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) predicts arrhythmic events in patients with chronic myocardial infarction.Patients with decreased left ventricular function due to chronic myocardial infarction are at increased risk for life-threatening arrhythmias related to infarcted tissue. LGE-CMR accurately detects infarct...

Ralf Wassmuth, Hassan Abdel-Aty, Steffen Bohl, Jeanette Schulz-Menger

European Radiology > 2011 > 21 > 8 > 1643-1650

Objectives Using cardiac magnetic resonance imaging (MRI) we tested the diagnostic value of various markers for amyloid infiltration. Methods We performed MRI at 1.5 T in 36 consecutive patients with cardiac amyloidosis and 48 healthy volunteers. The protocol included cine imaging, T2-weighted spin echo, T1-weighted spin echo before and early after contrast and late gadolinium enhancement. We compared...

Takotsubo cardiomyopathy after nasal application of epinephrine—A magnetic resonance study

Florian von Knobelsdorff-Brenkenhoff, Hassan Abdel-Aty, Jeanette Schulz-Menger

International Journal of Cardiology > 2010 > 145 > 2 > 308-309

Takotsubo cardiomyopathy (TTC), which is characterized by transient left ventricular impairment in absence of coronary artery disease, is usually associated with emotional or physical stress, supposing that catecholamines are involved in pathophysiology. The present article reports on two cases with characteristic features of TTC following nasal application of epinephrine during nasal surgery. Both...

Acute oedema in the evaluation of microvascular reperfusion and myocardial salvage in reperfused myocardial infarction with cardiac magnetic resonance imaging

Arintaya Phrommintikul, Hassan Abdel-Aty, Jeanette Schulz-Menger, Matthias G. Friedrich, więcej

European Journal of Radiology > 2010 > 74 > 3 > e12-e17

The accurate measurement of myocardial salvage is critical to the ongoing refinement of reperfusion strategies in acute myocardial infarction (AMI). Cardiac magnetic resonance imaging (CMR) can define the area at risk in AMI by the presence of myocardial oedema, identified by high signal intensity on T ₂ -weighted imaging with a short inversion time inversion-recovery (STIR) sequence. In addition,...

The Use of Cardiovascular Magnetic Resonance in Acute Myocardial Infarction

Hassan Abdel-Aty, Christoph Tillmanns

Current Cardiology Reports > 2010 > 12 > 1 > 76-81

Acute myocardial infarction (MI) results in reversible and irreversible injury to the myocardium, including stunning, edema, myocyte necrosis, and microvascular obstruction. Because of its unique tissue characterization capabilities, cardiovascular magnetic resonance provides a reliable means of visualizing and quantifying the extent of these injuries. Such characterization is readily achieved through...

Journal of the American College of Cardiology > 2009 > 53 > 17 > 1475-1487

Cardiovascular magnetic resonance (CMR) has become the primary tool for noninvasive assessment of myocardial inflammation in patients with suspected myocarditis. The International Consensus Group on CMR Diagnosis of Myocarditis was founded in 2006 to achieve consensus among CMR experts and develop recommendations on the current state-of-the-art use of CMR for myocarditis. The recommendations include...

Myocardial edema is a feature of Tako-Tsubo cardiomyopathy and is related to the severity of systolic dysfunction: Insights from T2-weighted cardiovascular magnetic resonance

Hassan Abdel-Aty, Myra Cocker, Matthias G. Friedrich

International Journal of Cardiology > 2009 > 132 > 2 > 291-293

We investigated if myocardial edema is a feature of Tako-Tsubo cardiomyopathy (TTC). Seven TTC patients in the acute phase were studied using cine, T2 and late enhancement cardiovascular magnetic resonance (CMR). A transmural area of high T2 signal was visible involving the mid-anterior wall and apical segments matching the distribution of hypokinesis. CMR-identified edema is a feature of TTC. This...

JACC: Cardiovascular Imaging > 2009 > 2 > 2 > 131-138

We sought to assess the value of cardiac magnetic resonance (CMR) to monitor the spectrum of myocarditis-related injuries over the course of the disease.Myocarditis is associated with a wide range of myocardial tissue injuries, both reversible and irreversible. Differentiating these types of injuries is a clinical demand.We studied 36 patients (31 males, age 33 ± 14 years) hospitalized with myocarditis...

Andre Rudolph, Hassan Abdel-Aty, Steffen Bohl, Philipp Boyé, więcej

Journal of the American College of Cardiology > 2009 > 53 > 3 > 284-291

We aimed to evaluate the incidence and patterns of late gadolinium enhancement (LGE) in different forms of left ventricular hypertrophy (LVH) and to determine their relation to severity of left ventricular (LV) remodeling.Left ventricular hypertrophy is an independent predictor of cardiac mortality. The relationship between LVH and myocardial fibrosis as defined by LGE cardiovascular magnetic resonance...
