Toxic effects of domoic acid in the seabream Sparus aurata.

Neurotoxicity induced in fish by domoic acid (DA) was assessed with respect to occurrence of neurotoxic signs, lethality, and histopathology by light microscopy. Sparus aurata were exposed to a single dose of DA by intraperitoneal (i.p.

Is there an anatomical substrate for idiopathic paroxysmal atrial fibrillation? A case-control echocardiographic study.

Aim: Idiopathic paroxysmal atrial fibrillation (AF) occurs in patients with apparently normal heart. Its mechanisms may be complex and are poorly understood. The aim of the study was to evaluate whether patients with idiopathic AF have any structural abnormality that may explain the occurrence of AF.

[Clinical and echocardiographic follow-up of patients with hypertrophic obstructive cardiomyopathy treated by percutaneous septal ablation].

Introduction And Objectives: Alcohol septal ablation is a therapeutic option for patients with hypertrophic obstructive cardiomyopathy who remain symptomatic despite medical treatment. Our aim was to monitor clinical and echocardiographic progression in patients with hypertrophic obstructive cardiomyopathy treated by septal ablation at our center.

Methods: Thirty-five septal ablations were performed in 34 patients (79% male) who had symptomatic hypertrophic obstructive cardiomyopathy despite optimum medical treatment.

[Left ventricular remodeling in patients with hypertrophic obstructive cardiomyopathy treated with percutaneous alcohol septal ablation: an echocardiographic study].

Introduction: In patients with hypertrophic obstructive cardiomyopathy, obstruction in the left ventricular outflow tract may generate more hypertrophy. Our aim was to evaluate the impact of reducing ventricular outflow tract obstruction on left ventricular hypertrophy and remodeling after alcohol septal ablation.

Patients And Method: 20 patients with hypertrophic obstructive cardiomyopathy who underwent alcohol septal ablation were included.
