Peak systolic velocity (Vmax, m/s) and Doppler-derived pressure gradient (ΔP, mmHg) in Newfoundland dogs for which the board-certified specialist (VC) in charge of the French cardiovascular breed screening program (2010–2023) could conclude to a definitive cardiac status regarding aortic stenosis (n = 876) and pulmonic stenosis (n = 879) out of the 921 Newfoundland dogs that underwent the French cardiovascular breed screening program (2010–2023).

Dogs with other heart diseases (n = 33) were excluded from the analysis.
