ASD (Atrial Septal Defect) and PS (Pulmonic Stenosis): CKCS, 1,5 years, weight loss, syncope, lethargy. Systolic heart murmur left and right heart base ~ 4/6 intensity inconstant (wich goes with inconstant v-max on spectral). Severe type B PS (severe hypoplasia of PV). Additionally small bidirectional Type 2 ASD. (seen on right parasternal 4 chamber long […]
SAS (Subaortic Stenosis): Boxer, 2 years, breeding examination. 4/6 systolic murmur left heart base. No clinical signs. There is a high grade SAS present. Treated with Atenolol (1.5mg/kg bid). Turbulence can be seen on CDI, was then exactly located by tracking the LVOT, AV and Aorta with PW. Given that the PW velocities alias, CW […]
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).
PDA (Patent Ductus Arteriosus) L to R: Papillon, 6 weeks old, weighing 550 g, The patient was much smaller than the littermates. A machinery murmur was present (maximum underneath left shoulder). Note that this puppy with L-R shunt has a normal systolic gradient across the shunt but the diastolic gradient is quite low (sign of […]
This is a 3-year old mix breed dog with moderate mitral insufficiency, nephritic syndrome and acute pulmonary hypertension potentially due to pulmonary thromboembolism.
4-year-old DSH Feline presented for anorexia. The clinical exam revealed a 4/6 systolic heart murmur. An echocardiogram was performed discovering Tetrology of Fallot; pulmonic stenosis, ventricular septal defect, right ventricular hypertrophy, overriding aorta. Unfortunately further analysis revealed Feline Infectious Peritonitis and the patient was eventually euthanized.
A 1-year-old French Bulldog was referred because of a heart murmur that was heard during routine examination. The owner had not noticed any problems. Clinical examination revealed a 4/6 systolic murmur with a maximum over the left heart base. Mucous membranes were pink, capillary refill time 1.5 sec. Pulse quality was a little bit weaker […]
