Transcatheter embolization of systemic-to-pulmonary artery fistulas in a dog using embolization coils and silk suture
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): R.L. Winter, J.A. Horton, D.K. Newhard, M. HollandAbstractA 4-month-old intact female Cavalier King Charles spaniel presented for evaluation of a left, basilar continuous murmur. Transthoracic echocardiography suggested anomalous vessels around the main pulmonary artery, and computed tomography angiography revealed two systemic-to-pulmonary artery fistulas. Transcatheter embolization of these fistulas was achieved with a combination of embolization coils and silk suture threads delivered through a microcatheter.

Balloon valvuloplasty in a dog with congenital bicuspid aortic valve and supravalvar aortic stenosis (atypical Shone's complex)
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): R.L. Winter, D.K. Newhard, A.R. Taylor, J.A. Johnson, E.D. Baravik-MunsellAbstractAn 8-month-old intact female pug was presented for evaluation and possible balloon valvuloplasty (BV) for severe aortic stenosis. A bicuspid, severely stenotic aortic valve of type 3 morphology with a supravalvar stenosis component was diagnosed, consistent with the diagnosis of atypical Shone's complex. There was severe concentric hypertrophy of the left ventricle, with increased echogenicity of the myocardium nearest to the endocardial border. Mild left...

Effect of sildenafil and pimobendan on intracardiac heartworm infections in four dogs
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): S.S. Tjostheim, H.B. Kellihan, K.A. Grint, R.L. StepienAbstractFour dogs, referred for management of heartworm (HW) disease, were found to have HWs entangled in their tricuspid valve apparatus. None of the dogs were actively hemolyzing or showed signs of acute cardiovascular collapse that would have necessitated emergency transvenous HW extraction, and surgery was not performed at time of presentation. The dogs received pimobendan and sildenafil within 24 h of identifying HW in the tricuspid valve apparatus, and the HW moved to the pu...

The Repeatability and Left Atrial Strain Analysis Obtained via Speckle Tracking Echocardiography in healthy Dogs
ConclusionsLeft atrial speckle tracking echocardiographic analysis provided useful information to assess the LA function in healthy dogs. The influencing factors on strain and SR variables including the age, body weight, and heart rate should be considered in interpretation of these parameters in a clinical setting.

Pericardial Effusion in a Dog with Pericardial Hemangiosarcoma
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): T. Gunasekaran, N.B. Olivier, R.C. Smedley, R.A. SandersAbstractAn adult Jack Russel terrier dog presented for evaluation of large-volume peritoneal and pleural effusion. Echocardiography revealed scant pericardial effusion and abnormally thickened pericardium. Electrocardiography revealed complete atrioventricular block with junctional and ventricular escape beats and occasional ventricular premature complexes. Computed tomography of the thorax confirmed diffuse abnormal thickening of the pericardium, and a tentative diagnosis of cons...

Doppler-derived echocardiographic evidence of pulmonary hypertension in cats with left-sided congestive heart failure
ConclusionsPulmonary hypertension identified by Doppler echocardiography is not a common finding in cats with L-CHF. Right-sided heart enlargement, more frequently observed, may raise the suspicion of PH in cats with L-CHF. (Source: Journal of Veterinary Cardiology)

Canine leishmaniasis associated with pericardial effusion in a 4-year-old dog
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): P. Sebastián-Marcos, G. Santarelli, S. Gómez, M. J. Fernández-del PalacioAbstractA 4-year-old crossbreed dog presented with a two-day history of lethargy and abdominal effusion. Physical examination and echocardiography revealed pericardial effusion with cardiac tamponade. Pericardiocentesis was performed. Intracytoplasmic Leishmania amastigotes were found on cytological examination of the pericardial fluid. The animal was treated with N-methylglucamine antimoniate and allopurinol. After an initial favorable response, cardiac tampo...

Coronary arteriovenous malformation in a dog with a complex arrhythmia and hypothyroidism
Publication date: June 2019Source: Journal of Veterinary Cardiology, Volume 23Author(s): R.R. Blake, M. Longo, G. Santarelli, T. Liuti, Y. Martinez-Pereira LdaVetAbstractA four-year-old Japanese Akita was referred for investigation of lethargy, exercise intolerance, and an irregular heart rhythm. He was diagnosed with atrial fibrillation, a complex ventricular arrhythmia, and hypothyroidism. Echocardiography identified a nest of anomalous vessels surrounding the heart and shunting into the pulmonary artery. Computed tomography confirmed a coronary arteriovenous malformation consisting of a coronary-to-pulmonary arterial co...

Cardiac pacemakers: a basic review of the history and current technology
Publication date: Available online 18 February 2019Source: Journal of Veterinary CardiologyAuthor(s): W.F. DeForgeAbstractIn the 60 years since the first human implant of a cardiac pacemaker, tremendous improvements have been made to devices themselves as well as the lead systems. Improvement in battery materials has allowed for production of smaller devices with greater longevity and a vast array of technologies allowing for communication between the device and the operator. Lead wires, typically to as the weakest part of the pacing system, have also seen a metamorphosis as improvements in conductor materials and hybrid i...

Right ventricular function and dyssynchrony measured by echocardiography in dogs with precapillary pulmonary hypertension
ConclusionsEchocardiographic RV function indices are impaired in dogs with precapillary PH. In addition, RV dilation and elevated systolic pulmonary arterial pressure estimated by echocardiography are associated with RV dyssynchrony. (Source: Journal of Veterinary Cardiology)

Indications for permanent pacing in dogs and cats
We described the etiology of bradyarrhythmias, clinical signs and electrocardiographic abnormalities, and the choice of pacing modality, taking into account how different choices may have different physiological consequences to selected patients. It is expected that this review will assist veterinarians in recognizing arrhythmias that may require permanent pacing and the risk-benefit of each pacing modality and its impact on outcome.
