Myxomatous mitral valve disease (MMVD), an important disease in senile small breed dogs, leads to deterioration of cardiovascular function and impairment of functional capacity resulting in poor quality of life. Submaximal treadmill running has been used as both cardiovascular training and testing worldwide in humans and recently in animals. The objectives of this study were to examine the effects of submaximal endurance training (ET) by treadmill running on safety, adverse events, cardiovascular adaptations, hematology, functional capacity, and the feasibility of submaximal treadmill running test and 6-minute walk test (6-MWT) in dogs with MMVD. Six adult beagle dogs with MMVD, stage B1 according to the American College of Veterinary Internal Medicine (ACVIM) guideline, were examined before the study, at weeks 4 and 8 of the ET. The cardiovascular functions assessed by echocardiography and electrocardiography, systolic blood pressure, hematology and blood chemistry profiles, and functional capacity were determined. All dogs completed all tests and ET sessions without clinical complication. ET resulted in significant improvement in physical capacity measured by submaximal treadmill running test and 6-MWT, while cardiac function parameters were not altered. Moreover, serum creatinine was significantly decreased. In conclusion, ET and submaximal exercise tests are clinically feasible. The ET can improve physical capacity in dogs with MMVD, stage B1. Therefore, supervised moderate ET and submaximal exercise tests should be incorporated in MMVD management. [ABSTRACT FROM AUTHOR]

The article presents a case study of a one-year-old male Chihuahua. He is presented with history of heart murmur to small animal teaching hospital at Chulalongkorn University of Bangkok, Thailand. The dog don't have clinical signs of cardiovascular disease like coughing and his blood test was normal. In electrocardiograph, mild interstitial pattern was found for caudal lung lobe.

The article presents a case study of 14-year-old castrated male mixed breed dog, with systolic murmur heart sound grade and was given angiotensin converting enzyme inhibitor for same. Physical examination showed cardiomegaly with mild peripheral lung infiltration and thickening of mitral valve along with thrombocytopenia, increased liver enzymes. Doxycycline was given to dog during treatment.

The article discusses the medication and echocardiography (ECG) findings of a 14-year-old female Labrador. Among the ECG interpretation that were discussed include the sinus arrhythmia with periodic ventricular bigeminy, sinus arrhythmia, and ventricular bigeminy. Several ECG strips of the Labrador are also presented.

The first case interventional technique of Patent Ductus Arterious (PDA) correction was conducted in a 2 years old Golden Retriever. The dog was presented with continuous murmur with a marked left-side heart enlargement, insufficiency of pulmonic, mitral, and aortic valves. The definitive diagnosis for PDA was performed by echocardiography. The dog received PDA correction with interventional PDA occluding device consisting of nitinol wire mesh under fluoroscope at the Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University with collaboration by medical expertise from Faculty of Medicine, Chulalongkorn University. The procedure was successful as measured by complete occlusion of PDA and no major complication. At one month after correction, the dog was more healthy and energetic while echocardiography showed a reduction of left ventricular dimension and improved valvular insufficiency. At six months after correction, the dog had smaller heart size with improved cardiac function. [ABSTRACT FROM AUTHOR]
