Could successful cryoballoon ablation of paroxysmal atrial fibrillation prevent progressive left atrial remodeling?

Background: Radiofrequency catheter ablation of atrial fibrillation (AF) has been proved to be effective and to prevent progressive left atrial (LA) remodeling. Cryoballoon catheter ablation (CCA), using a different energy source, was developed to simplify the ablation procedure. Our hypothesis was that successful CCA can also prevent progressive LA remodeling.

Comparison of tissue Doppler velocities obtained by different types of echocardiography systems: are they compatible?

Background: Both systolic and diastolic tissue Doppler (TD) velocities have an important diagnostic and prognostic role in cardiology. We aimed to compare TD velocities between two different echocardiography systems.

Patients: Thirty-one consecutive patients (mean age: 65.

Predictors of the outcome of thrombolytic therapy in prosthetic mitral valve thrombosis: a study of 62 events.

Background And Aim Of The Study: Treatment strategies and guidelines in the management of prosthetic valve thrombosis (PVT) remain controversial. The study aim was to assess the success and complication rate of thrombolytic therapy (TT) by comparing thrombus size, severity of symptoms, type of prosthetic valve, and time since valve implantation.

Methods: Between April 1993 and December 2006, TT was administered for 62 thrombotic events in 55 patients with mitral PVT.

Assessment of diastolic dysfunction in elderly hypertensive patients using integrated Doppler echocardiography.

Unlabelled: The aim of this study was to assess the different stages of diastolic dysfunction (DD) in elderly, asymptomatic, hypertensive patients with preserved systolic function, and to investigate the role of Tissue Doppler imaging (TDI) and Pulmonary venous (PV) flow added to the routine echocardiographic assessment. Patients. 322 patients (age: 70.

[Use of anticoagulant therapy in non-valvular atrial fibrillation. Analysis of a Hungarian cohort].

Unlabelled: In nonvalvular atrial fibrillation stroke prevention by anticoagulation is clearly recommended by evidence based medicine. Underusage of coumarin treatment however is a general problem. The aim of this study was the analysis of prehospital and hospital practice of anticoagulant therapy in a Hungarian cohort.
