Outcomes following combined percutaneous balloon valvuloplasty and external beam radiation therapy for the treatment of congenital pulmonic stenosis in four dogs
Publication date: Available online 3 February 2020Source: Journal of Veterinary CardiologyAuthor(s): Koichi Nagata, Amanda E. ColemanAbstractValve restenosis following percutaneous balloon pulmonary valvuloplasty (BPV) for the treatment of congenital pulmonic stenosis (PS) may occur in up to 17% of canine cases. Outcomes in dogs with PS that are treated with repeat BPV following restenosis have not been described. The present report details the clinical courses of four dogs with congenital PS, previously treated with conventional BPV and atenolol (n = 4) or atenolol alone (n = 1), two with anomalous, circumpulmonary corona...

DELay of appearance of sYmptoms of canine degenerative mitral valve disease treated with spironolactone and benazepril: The DELAY study
ConclusionsThis study failed in demonstrating that combined administration of spironolactone and benazepril delays onset of HF in dogs with preclinical MMVD. However, such treatment induces beneficial effects on cardiac remodeling and these results could be of clinical relevance. (Source: Journal of Veterinary Cardiology)

Pulmonary vein to pulmonary artery ratio in healthy and cardiomyopathic cats
ConclusionsOur study provides reference values for PV and PA variables in cats. Moreover, PV/PA variables performed better than LA:Ao in discriminating cardiomyopathic cats with and without CHF. (Source: Journal of Veterinary Cardiology)

Ventricular arrhythmia and sudden cardiac death in young Leonbergers
ConclusionsSudden cardiac death in young Leonbergers is associated with malignant VA characterized by complexity and polymorphic nature. Diagnosis is based on 24-hour Holter monitoring. Pedigree analysis suggests that the arrhythmia is familial. (Source: Journal of Veterinary Cardiology)

Two-dimensional echocardiographic left- atrial-to-aortic ratio in healthy adult dogs: a reexamination of reference intervals
ConclusionsReference limits were either confirmed or established for the common two-dimensional methods of assessing relative left atrial size in healthy dogs. Clinicians should use caution when diagnosing mild left atrial enlargement in certain dog breeds and should examine the weight-based aortic dimensions in such cases.

Prevalence of Bartonella sp. in United States military working dogs with infectious endocarditis: a retrospective case-control study
ConclusionsBartonella sp. Infections were correlated with cardiopathies in US military working dogs. Systemic use of insecticides against ectoparasites and regular testing of MWDs for Bartonella infection seem highly appropriate to prevent such life-threatening exposures.

Evaluation of non-ECG and ECG-gated computed tomographic angiography for three-dimensional printing of anomalous coronary arteries in dogs with pulmonic stenosis
ConclusionIn dogs, CTA is effective for diagnosis of coronary artery anomalies. Printed 3D models of ECG-gated studies were of excellent quality and allowed direct visualization of abnormal coronary artery anatomy. The usefulness of these models to improve the understanding of anomalous coronary artery anatomy could be evaluated in future studies. (Source: Journal of Veterinary Cardiology)

Comparison between the effects of torsemide and furosemide on the renin-angiotensin-aldosterone system of normal dogs
ConclusionsAt approximately equipotent dosages (20:1), torsemide and furosemide produced comparable renin-angiotensin-aldosterone system activation. Torsemide’s similar potassium excretion profile to furosemide decreases support for a hypothesized mineralocorticoid-receptor blocking capability. (Source: Journal of Veterinary Cardiology)

Echocardiographic assessment of right heart size and function in dogs with pulmonary valve stenosis
ConclusionsRight heart remodeling and RV dysfunction are common in dogs with PS and are associated with echocardiographic and clinical severity. Results support the quantitative assessment of right heart size and function in dogs with PS. (Source: Journal of Veterinary Cardiology)

Successful transcatheter pulmonary valve implantation in a dog: first clinical report
We report here the first successful transcatheter implantation of a stented valve in a pulmonary position in a dog with congenital pulmonary valve disease. A 3-year-old, 10.9 kg, client-owned Beagle dog was referred for a follow-up visit after a percutaneous balloon valvuloplasty performed 22 months before for treatment of a severe type A valvular pulmonary stenosis. The Doppler-derived peak pressure gradient (PG) was 348 mmHg before the procedure and 66 mmHg 24 hours after. The dog was lethargic. Echocardiography revealed a mild pulmonary stenosis (PG - 43 mmHg), severe pulmonary regurgitation, and secondary severe right ...

Schertenleib, Tony M. GlausAbstractA 2 year old Airedale Terrier was presented with exercise intolerance since birth and newly developed chylous pleural effusion. Imaging procedures including echocardiography, cardiac magnetic resonance imaging, computed tomography, and selective angiography revealed an aberrant connection of the azygos vein and the left atrium, a membrane in the right atrium consistent with cor triatriatum dexter, and a patent ...

A Pilot Study Evaluating Cutting and High-Pressure Balloon Valvuloplasty for Dysplastic Pulmonary Valve Stenosis in 7 Dogs
ConclusionsThis procedure is a feasible therapeutic transcatheter intervention for dogs with dysplastic pulmonary valves and appears safe in this small cohort. The ideal selection criteria and rate of restenosis for this procedure is under investigation, and long-term follow-up as well as a large, randomized, controlled study are necessary to demonstrate efficacy.
