Early detection of cardiac motion abnormalities is one of the main goals of quantitative cardiac image processing. This article presents a new method to compute the 2-D myocardial motion parameters from gray-scale 2-D echocardiographic sequences, making special emphasis on the validation of the proposed technique in comparison with Doppler tissue imaging.(More)
AIMS Adipose-derived regenerative cells (ADRCs) can be isolated from liposuction aspirates and prepared as fresh cells for immediate administration in cell therapy. We performed the first randomized, placebo-controlled, double-blind trial to examine the safety and feasibility of the transendocardial injections of ADRCs in no-option patients with ischemic(More)
This study was conducted to assess the usefulness of transesophageal echocardiography (TEE) as a guide in the percutaneous transcatheter occlusion of paravalvular defects and in subsequent follow-up. In 27 consecutive patients with mitral paravalvular leaks with significant regurgitation considered to be poor surgical candidates who were treated with(More)
Vortices may have a role in optimizing the mechanical efficiency and blood mixing of the left ventricle (LV). We aimed to characterize the size, position, circulation, and kinetic energy (KE) of LV main vortex cores in patients with nonischemic dilated cardiomyopathy (NIDCM) and analyze their physiological correlates. We used digital processing of(More)
STUDY OBJECTIVES To assess the effect of gender on the in-hospital management of patients with acute inferior or posterior myocardial infarction (MI). DESIGN Retrospective analysis of clinical records. Gender differences in management and prognosis were assessed by stepwise multiple logistic regression analysis. SETTING University, large-volume,(More)
OBJECTIVE Myocardial Infarction with Non-Obstructed Coronary Arteries (MINOCA) is common, but the causes are to a large extent unknown. Thus, we aimed to study the prevalence of myocarditis and "true" myocardial infarction determined by cardiac magnetic resonance (CMR) imaging in MINOCA patients, and risk markers for these two conditions in this population.(More)
3. tient. On the other hand, the fact that it can be connected to a rmanent pacemaker generator allows for programming of more ysiologic pacing modes that help to maintain the patient in a able clinical condition and allow the patient to walk about ithout clinical deterioration. Such advantages are particularly sirable in patients who are totally dependent(More)
OBJECTIVES The aim of our study was to assess whether left atrial appendage (LAA) ligation in patients undergoing mitral valve replacement is associated with the risk of future embolisms. BACKGROUND Previous studies show that the LAA plays an important role in the development of intracardiac thrombus. According to this decisive role, LAA surgical closure(More)
BACKGROUND The percutaneous closure of mitral paravalvular leaks has been reported in patients who are poor operative candidates. Unsuccessful percutaneous closure of leaks may be related to morphologic characteristics of the defects. METHODS Ten patients were selected from a database for mitral dehiscence closure, in whom two-dimensional transesophageal(More)
Isolated noncompaction of the ventricular myocardium is frequently mistaken for other cardiomyopathies. We report a case of a 49-year-old woman admitted to hospital for heart failure and initially given the diagnosis of apical hypertrophic cardiomyopathy. In this case, myocardial contrast echocardiography and magnetic resonance imaging played a pivotal role(More)
