History
PDA (Patent Ductus Arteriosus) Bidirectional: This 700 g, 6-week old Papillon puppy had inconstant systolic murmur under left and right shoulder. The patient was much smaller than the littermates. On the clips/images of the bidirectional PDA one can easily see the concentric RV hypertrophy as a result of severe PHT (pulmonary hypertension).
