Seventy-one patients with achalasia were studied. They were 2-29 years old. Dysphagia to solid food was the main presenting symptom (100 percent). Reliable and persistent manometric findings were absence of normal contraction waves in association with the presence of low amplitudes simultaneous waves in all cases. In vigorous achalasia, weight loss (P=0.001), dysphagia (P=0.012) and LES pressur...

BACKGROUND Transformation from persistent to paroxysmal atrial fibrillation (AF) after ablation suggests modification of the underlying substrate. We examined the nature of initial arrhythmia recurrence in patients with nonparoxysmal AF undergoing antral pulmonary vein isolation and nonpulmonary vein trigger ablation and correlated recurrence type with long-term ablation efficacy after the last...
