We recently reported that esophageal contraction reduces esophageal wall perfusion in an animal study. Our aim was to determine esophageal wall blood perfusion (EWBP) during esophageal contraction and transient lower esophageal sphincter relaxations
Mechanism of stretch-activated excitatory and inhibitory responses in the lower esophageal sphincter

We recently found that an orally directed stretch of the esophagus activates a neurally mediated relaxation of the lower esophageal sphincter (LES). Goals of our study were to characterize the neural mechanisms responsible for axial and transverse st

Myocardial blood flow occurs during the diastolic phase of the cardiac cycle, because myocardial contraction during the systolic phase impedes myocardial perfusion. Using laser Doppler perfusion technique, we studied the effect of esophageal contract

We tested the hypothesis that the pericardium, by restricting heart size, limits maximal cardiac output and oxygen consumption. We studied 15 pigs. Five underwent maximal treadmill running before and 14–21 days after thoracotomy and pericardiectomy

Background & Aims: Patients with high-amplitude esophageal contractions (nutcracker esophagus [NCE]) show asynchrony of circular muscle (CM) and longitudinal muscle (LM) contraction during peristalsis. The goal of our study was to determine if this a

Left ventricular regional wall motion was evaluated in 11 patients with pulmonary hypertension and 18 control subjects. All 11 patients had secondary pulmonary hypertension and less than 20% measured diameter stenosis in any vessel. This study utiliz
