Cerebral small vessel disease in a six-month-old Rottweiler with severe subaortic stenosis.

A six-month-old, 23.5-kg female Rottweiler with severe subaortic stenosis (SAS) was referred for cardiological management due to exercise intolerance. Transthoracic echocardiography revealed severe SAS with a pressure gradient of 130 mmHg. A combined cutting balloon and high-pressure balloon dilatio...

Use of the subcostal view for obtaining aortic spectral Doppler-derived outflow velocities in cats.

In dogs and foals, spectral Doppler-derived aortic outflow velocities (AVs) obtained from the subcostal (SC) view provide higher values than the left parasternal apical five-chamber (LAp) view. In cats, use of the SC view for obtaining AV has not been reported. The aim of the study was to compare AV...

Evaluation of Changes in Heart Rate Variability Associated with Puppy Growth Using Phase-Rectified Signal Averaging (PRSA) and Non-Gaussianity Index.

Heart rate variability (HRV) reflects autonomic nervous system (ANS) activity through nonlinear mechanisms, including complex beat-to-beat fluctuations and chaos-like dynamics of healthy cardiac rhythms. However, conventional HRV indices often show inconsistent interpretations of sympathetic activit...

Cardiac Abnormalities in Feline Hyperthyroidism.

Hyperthyroidism is a common endocrine disorder in elderly cats, often leading to concurrent cardiac abnormalities. Understanding the development of these cardiac abnormalities and the effect of treatment is crucial for optimizing monitoring strategies and long-term management. Hyperthyroid cats freq...

Prognostic Value of Body Weight-Independent Tricuspid Annular Plane Systolic Excursion to Systolic Pulmonary Arterial Pressure Ratio in Canine Precapillary Pulmonary Hypertension: A Retrospective Study.

The prognostic use of both the echocardiographic parameters tricuspid annular plane systolic excursion (TAPSE) and systolic pulmonary artery pressure (sPAP) in dogs with pulmonary hypertension (PH) has shown conflicting results. The ratio of TAPSE/sPAP, not yet described in dogs, is used for the eva...
