Coronary fibromuscular dysplasia is uncommon, and even rarer its unstable and recurrent course. We present the unique case of a 52-year-old woman who underwent in total 12 coronary angiographies and three percutaneous coronary intervention within 24 months because of repetitive acute coronary syndromes due to refractory spasm, dissection, restenosi...
Article
Background: Studies indicate no clear impact of intracoronary injection of bone-marrow unselected mononuclear cells (BM-MNC) after acute myocardial infarction (AMI) on left-ventricular function (LVEF). Strain parameters by cardiovascular magnetic resonance (CMR) have been proposed to be more sensitive to functional changes of the heart. The aim of...
Article
Recent advances in different percutaneous treatments made insertion of large-caliber sheaths in the femoral veins more common. Venous punctures are historically managed by initial manual compression with subsequent application of a compression bandage and bed rest. We describe a modified "figure-of-eight" suture technique for minimizing the risk of...
Article
Objectives This study sought to test the accuracy of strain measurements based on anatomo-electromechanical mapping (AEMM) measurements compared with magnetic resonance imaging (MRI) tagging, to evaluate the diagnostic value of AEMM-based strain measurements in the assessment of myocardial viability, and the additional value of AEMM over peak-to-pe...

Background: Validation of voltage-based scar delineation has been limited to small populations using mainly endocardial measurements. The aim of this study is to compare unipolar voltage amplitudes (UnipV) with scar on delayed enhancement cardiac magnetic resonance imaging (DE-CMR). Methods: Heart failure patients who underwent DE-CMR and electr...

Background: Both duration and morphology of the T-wave are regarded important parameters describing repolarization of the ventricles. Conventionally, T-wave concordance is explained by an inverse relation between the time of depolarization (TD) and repolarization (TR). Little is known about T-wave morphology and TD-TR relations in patients with he...

CCTA and CA images...
Conference Paper
This document aims at introducing the development and the construction of a pre-industrial automatic heart resuscitator, able to drastically reduce the X-Rays masking in the action zone. Thanks to lateral actuation of the massage and the carbon fiber choose for building the chest contact point bridge, it was possible to pass the limitations view un...
Article
Full-text available
Left ventricular thrombus (LVT) formation may worsen the post-infarct outcome as a result of thromboembolic events. It also complicates the use of modern antiplatelet regimens, which are not compatible with long-term oral anticoagulation. The knowledge of the incidence of LVT may therefore be of importance to guide antiplatelet and antithrombotic t...
Article
Background: Combined measurement of electrical activation and mechanical dyssynchrony in heart failure (HF) patients is scarce but may contain important mechanistic and diagnostic clues. Objective: The purpose of this study was to characterize the electromechanical (EM) coupling in HF patients with prolonged QRS duration. Methods: Ten patients...

Article
Over four million Europeans and a similar number Americans suffer from significant mitral regurgitation (MR). Approximately 250,000 new patients are diagnosed with the disease annually. The disorder generally evolves insidiously over many years because the heart compensates for the regurgitant volume by left atrial enlargement, left ventricular (LV...

Article
The X-linked ANG II type 2 receptor (AT2) is supposed to be involved in cardiovascular disorders. Two studies associated the A allele of the AT2 gene polymorphism (PM) 1675 G/A with left ventricular hypertrophy in men and coronary ischemia in women. Because the PM is located in the short intron 1 of the AT2 gene within a sequence motif similar to t...
Article
Expression levels of angiotensin II type 1 and type 2 receptors (AT1, AT2) vary at different cardiac localizations and are regulated in cardiac diseases. Differential splicing of the 5' untranslated exons of the primary AT1 mRNA transcripts may modulate translational efficiency and thus receptor expression. We therefore searched for AT1 and AT2 mRN...
