TABLE 3.

Specific echocardiographic measures of pulmonary hypertension, ductal diameter, and left atrial size in dogs and cats

Echocardiographic findings
Variable Result
MDD type II 5.30 mm (±2.45)
MDD type III 6.85 mm [4.90‐8.87]
MDD overall 6.14 mm (±2.78)
TR maximal velocity 5.14 m/s (±0.72)
PR maximal velocity 3.90 m/s (±0.59)
LA : Ao 1.28 (±0.26)

Note: Normally distributed data are presented as mean (±SD) and nonnormally distributed data are reported as median [range].

Abbreviations: LA : Ao, left atrial to aortic ratio; MDD, minimal ductal diameter; PR, pulmonic regurgitation; TR, tricuspid regurgitation..
