Intervertebral disk disease at T12\u201313 was diagnosed, and a hemilaminectomy was performed. Three days after surgery, the dog developed a ventricular tachyarrhythmia. Severe left and mild right ventricular hypertrophy were detected by echocardiography.<\/jats:p>\n<jats:p><jats:bold>TREATMENT AND OUTCOME<\/jats:bold> The arrhythmia was controlled with sotalol. Phenylpropanolamine administration was discontinued immediately before surgery and was not resumed. Heart rate and rhythm and blood pressure were within reference limits, and the ventricular hypertrophy had almost completely resolved 5 months later. Sotalol administration was discontinued. Shortly after the 5-month recheck evaluation, PPA administration was resumed, albeit at a lower dosage than that before surgery, for control of urinary incontinence. At the 10-month recheck evaluation, the dog was hypertensive and ventricular hypertrophy had recurred. Discontinuation of PPA administration was recommended but not heeded. The dog developed marked azotemia 1.5 years after surgery, which was managed by the referring veterinarian, and was subsequently lost to follow-up.<\/jats:p>\n<jats:p><jats:bold>CLINICAL RELEVANCE<\/jats:bold> The fact that the ventricular hypertrophy almost completely resolved when PPA administration was discontinued and then recurred after it was resumed strongly suggested the drug was an important contributing factor to the cardiac disease of this patient. Patients receiving PPA on a long-term basis should be frequently monitored for cardiac disease, and use of other adrenergic receptor agonists should be avoided in such patients.<\/jats:p>","DOI":"10.2460\/javma.253.11.1452","type":"journal-article","created":{"date-parts":[[2018,11,19]],"date-time":"2018-11-19T16:20:45Z","timestamp":1542644445000},"page":"1452-1459","source":"Crossref","is-referenced-by-count":0,"title":["Myocardial
