We examined diastolic transmitral, left atrial appendage, and pulmonary venous flow pulsed-wave Doppler velocities in five dogs sedated with Valium and ketamine both before and 1 week after rapid (400 beats/min) atrial pacing with transesophageal ech

Objective: To determine the left atrial mechanical and biochemical adaptations to congestive heart failure, 10 dogs with rapid atrial and ventricular pacing and seven control dogs were studied. Methods: Animals were instrumented with left atrial sono

Human chymase is a serine proteinase that converts angiotensin (Ang) I to Ang II independent of angiotensin converting enzyme (ACE) in vitro. The effects of chymase on systemic hemodynamics and left ventricular function in vivo were studied in nine c

BACKGROUND Contractile function of the ex vivo, isolated left atrium (LA) has been described by a time-varying elastance, but this atrial chamber property has not been shown in vivo. METHODS AND RESULTS Instantaneous LA pressure-volume (P-V) relation

We studied seven open-chest anesthetized dogs to test the hypothesis that left atrial (LA) compliance is increased after pericardiectomy and to determine the effect of pericardiectomy on left atrial reservoir and conduit function. Two orthogonal sono

We developed a technique for left atrial (LA) volume estimation using two pairs of sonomicrometers sewn to the anteroposterior (LAX) and mediolateral (SAX) LA diameters and validated the method against water displacement of LA casts in 15 dogs. LA pr

Studies in the rapid-pacing model of heart failure have shown that left ventricular (LV) systolic function normalizes on cessation of pacing and LV diastolic dysfunction persists, but there is no information regarding atrial function under these cond

Background Many of the cardiovascular manifestations of thyroid hormone excess resemble those produced by sympathoadrenal stimulation. The objective of this study was to determine the effects of thyroid hormone excess on myocardial β-adrenergic expr

The transcriptional, posttranscriptional, and related functional effects of thyroid hormone on primate myocardium are poorly understood. Therefore, we studied the effects of thyroid hormone on sarcoplasmic reticulum (SR) Ca 2+ -cycling proteins and m
