Breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. Labrador Retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. So, the present study was aimed to determine the M-mode...

pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...

STUDY OBJECTIVE To analyze the extent of pericardial constraint on right ventricular function in humans. PATIENTS AND METHODS Twenty patients, 59 +/- 2 (mean +/- SEM) years old, undergoing coronary bypass surgery. Right ventricular volumes and pressures were evaluated using a rapid response Swan-Ganz thermodilution catheter. INTERVENTIONS Parameters were determined before and after pericard...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

OBJECTIVE To evaluate the long-term effects of septic shock on cardiac function in children treated with inotropic and/or vasoconstrictive agents for 24 hours or longer. DESIGN Cohort study. SETTING Tertiary pediatric intensive care unit and outpatient follow-up clinic. PARTICIPANTS One hundred eight of 144 eligible children who were admitted to our tertiary pediatric intensive care unit ...

Left ventricular function was assessed by angiographic methods in 40 patients (ages 3-27), 1-12 years following repair of tetralogy of Fallot. Twenty of the 40 patients (group A) had a satisfactory repair with a pulmonary-systemic flow ratio (Qp/Qs) less then or equal to 1.5 and a right ventricular systolic pressure of less than or equal to 60% of the left ventricular value. The other 20 patien...
