Effect of Body Position, Exercise, and Sedation on Estimation of Pulmonary Artery Pressure in Dogs with Degenerative Atrioventricular Valve Disease
Conclusions and Clinical ImportanceThe increase in TRFV observed with sedation could change assessment of PH severity and impact prognostication and interpretation of treatment response. Further studies with invasive validation are needed.

Echocardiographic and electrocardiographic parameters during the normal postpartum period in toy breeds of dogs
In conclusion, there were changes in systolic function and some structural adaptive changes in the bitch during the first 80days postpartum. In addition, maternal heart rate and corrected QT interval decreased, while P wave and QRS amplitudes increased.

Maternal and fetal effects of dexmedetomidine infusion in pregnant ewes anesthetized with sevoflurane.
CONCLUSIONS AND CLINICAL RELEVANCE Pregnant ewes receiving a combination of sevoflurane and an infusion of dexmedetomidine without a loading dose had cardiac index in acceptable ranges and maintained normoxia. This balanced anesthesia did not produce significant changes in fetal blood pressure or heart rate. However, the increase in fetal plasma lactate concentration and changes in maternal pulmonary vascular resistance and uterine blood flow require further investigation to better elucidate these effects.

Comparison of cardiac measurements by multi-detector computed tomography angiography and transthoracic echocardiography in English bulldogs
Conclusion Multi-detector-CT ECG-gated cardiac angiography is possible in sedated, non-intubated English bulldogs. Differences were found between some cardiac dimensions as measured by TTE in the awake dog and compared with sedated CTA, indicating the two methodologies are not equivalent. Sedated, non-intubated CTA yielded high-quality imaging with strong intraobserver and interobserver measurement repeatability in English bulldogs.

Quantification of right ventricular volume measured by use of real-time three-dimensional echocardiography and electrocardiography-gated 64-slice multidetector computed tomography in healthy dogs.
CONCLUSIONS AND CLINICAL RELEVANCE There was substantial variance for RVV measured by use of 3DE in healthy dogs and a significant underestimation of volumes, compared with results for MDCT, despite the fact there were no significant differences in SV and EF.

Effect of different analgesic techniques on hemodynamic variables recorded with an esophageal Doppler monitor during ovariohysterectomy in dogs.
This study compared the efficacy of intravenous (IV) fentanyl and ketamine with lumbosacral epidural lidocaine in dogs undergoing ovariohysterectomy. Dogs with esophageal Doppler monitoring (n = 112) were included in this retrospective study. All dogs were premedicated with dexmedetomidine and methadone, induced with IV propofol or alfaxalone and maintained using isoflurane and IV fentanyl, IV ketamine, or epidural lidocaine. Heart rate (HR), mean arterial pressure (MAP), expired fraction of isoflurane (ETIso), stroke distance (SD), minute distance (MD), peak velocity (PV) and mean acceleration (MA) were recorded before an...

Change of heart dimensions and function during pregnancy in goats
Publication date: June 2018 Source:Research in Veterinary Science, Volume 118 Author(s): Olga Szaluś-Jordanow, Michał Czopowicz, Lucjan Witkowski, Agata Moroz, Marcin Mickiewicz, Tadeusz Frymus, Iwona Markowska-Daniel, Emilia Bagnicka, Jarosław Kaba The study aimed to evaluate the effect of pregnancy on heart diameters and function in goats. Transthoracic echocardiography of 12 female dairy goats of two Polish regional breeds was performed. A Mindray M7 diagnostic ultrasound system with Phased Array transducer was used. Simultaneously, electrocardiography was recorded. All animals were examined four times – at mating...

Usefulness of focused cardiac ultrasonography for predicting fluid responsiveness in conscious, spontaneously breathing dogs.
CONCLUSIONS AND CLINICAL RELEVANCE: The evaluated echocardiographic variables were useful for noninvasive prediction of fluid responsiveness in conscious dogs and could be valuable for informing clinical decisions regarding fluid therapy.

Echocardiographic assessment of left ventricular systolic function in neonatal calves with naturally occurring sepsis or septic shock due to diarrhea
The objectives of this study were to evaluate the clinical value of echocardiography for monitoring left ventricular (LV) systolic function in septic calves. A prospective longitudinal study was performed using a convenience sample. Twenty septic calves and 10 healthy calves were enrolled in the study. Arterial blood pressure (BP) was measured and M-mode echocardiography performed to characterize LV systolic function; the latter included measurement of ejection fraction, EF; stroke volume, SVI and cardiac output indexed to body weight, CI; E-point of septal separation, EPSS; pre-ejection period, PEP; ejection time, LVET; r...

Cardiovascular and respiratory effects of carbon dioxide pneumoperitoneum in the domestic rabbit (Oryctolagus cuniculus).
In conclusion, pneumoperitoneum with carbon dioxide causes an increase in ETCO2, PaCO2, and PIP, whereas cardiac output and CI decrease. These cardiorespiratory changes should be considered when determining the optimal IAP for laparoscopic procedures in rabbits.

Quantitative assessment of left ventricular volume and function by transthoracic and transesophageal echocardiography, ultrasound velocity dilution, and gated magnetic resonance imaging in healthy foals.
CONCLUSIONS AND CLINICAL RELEVANCE: All assessed modalities yielded clinically acceptable measurements of LVEDV, LVESV, and function, but those measurements should not be used interchangeably when monitoring patient progress.
