Spontaneous ischaemic stroke lesions in a dog brain: neuropathological characterisation and comparison to human ischaemic stroke
Dogs develop spontaneous ischaemic stroke with a clinical picture closely resembling human ischaemic stroke patients. Animal stroke models have been developed, but it has proved difficult to translate results ...

Ischemic stroke in greyhounds
Stroke can be the result of ischemic or hemorrhagic events that cause decreased perfusion to the entire brain or to a specific region of the brain. Ischemic stroke is the result of vascular occlusion secondary to a thrombus or embolus. Hemorrhagic stroke is the result of bleeding.

Electrical velocimetry for noninvasive cardiac output and stroke volume variation measurements in dogs undergoing cardiovascular surgery
Conclusions and clinical relevanceIn dogs undergoing cardiovascular surgery, EV provided accurate CO measurements compared with CIPAC, although its trending ability was poor. Further, SVV by EV, but not CVP, reliably predicted fluid responsiveness during mechanical ventilation in dogs.

Comparison of left and right ventricular stroke volume of dogs calculated on the basis of morphology and blood flow determined by use of cardiac magnetic resonance imaging.
CONCLUSIONS AND CLINICAL RELEVANCE In contrast to quantification based on blood flow, calculation on the basis of morphology for the short-axis plane significantly underestimated SV, probably because of through-plane motion and complex right ventricular anatomy. PMID: 28945128 [PubMed - in process]

Neurological signs in 23 dogs with suspected rostral cerebellar ischaemic stroke
In dogs with ischaemic stroke, a very common site of infarction is the cerebellum. The aim of this study was to characterise neurological signs in relation to infarct topography in dogs with suspected cerebell...

The Influence of Emotional Stress on Doppler‐derived Aortic Peak Velocity in Boxer Dogs
Conclusion and Clinical ImportanceAortic peak velocity was affected by emotional stress during echocardiographic examination both in SAS‐affected and normal Boxers. In normal Boxers, aortic root size weakly affected AoPVs, but did not affect AoPV0–AoPV1. Stroke volume seems to play a major role in stress‐related AoPV increases in normal Boxers. Emotional stress should be taken into account when screening for SAS in the Boxer breed.

Esophageal Doppler-derived indices and arterial load variables provide useful hemodynamic information during assessment of fluid responsiveness in anesthetized dogs undergoing acute changes in blood volume
Am J Vet Res. 2023 Feb 1:1-11. doi: 10.2460/ajvr.22.11.0198. Online ahead of print.ABSTRACTOBJECTIVE: To investigate the relationship between invasively measured stroke volume (SV) and (1) esophageal Doppler-derived indices such as stroke distance (StrokeD), flow time corrected (FTc), stroke distance variation (SDV), and peak velocity variation (PVV); and (2) arterial load (AL) variables during evaluation of fluid responsiveness (FR) in anesthetized dogs undergoing sudden hemodynamic shifts in blood volume.ANIMALS: 6 healthy male dogs.PROCEDURES: Dogs were anesthetized with isoflurane, ventilated mechanically, and instrume...

Comparison of echocardiography with dual-source computed tomography for assessment of left ventricular volume in healthy Beagles.
Conclusions and Clinical Relevance-LV volume determined via the Teichholz method was more similar to that determined via DSCT than was the LV volume determined via the modified Simpson method. The modified Simpson method underestimated LV volume, compared with that obtained via the Teichholz method, in both anesthetized and awake dogs. PMID: 23270347 [PubMed - in process]

Cardiovascular effects of dexmedetomidine, with or without MK‐467, following intravenous administration in cats
Conclusion and clinical relevanceFollowing IV co‐administration, MK‐467 effectively attenuated dexmedetomidine‐induced cardiovascular effects in cats. The drug combination resulted in transient reduction in arterial blood pressure, without causing hypotension.

Assessment of left ventricular volume and function in healthy dogs by use of one-, two-, and three-dimensional echocardiography versus multidetector computed tomography.
CONCLUSIONS AND CLINICAL RELEVANCE Values for EDV and ESV obtained by use of 3-D echocardiography, including RTBPE and RT3DE, had the highest correlation with slight underestimation, compared with values obtained by use of MDCT. This was similar to results for 3-D echocardiography in human medicine. PMID: 27805446 [PubMed - in process]

Investigation of the influence of manual ventilation-controlled respiration on right ventricular pressure-volume loops and echocardiographic variables in healthy anesthetized dogs
CONCLUSIONS AND CLINICAL RELEVANCE: Specific RV echocardiographic variables were significantly affected by respiration. In contrast, RVS and RVSR determined with RVGA were not affected by respiration and were associated with hemodynamic indicators of RV contractility.PMID:34669489 | DOI:10.2460/ajvr.82.11.865
