Dilated cardiomyopathy in the Newfoundland: a study of 37 cases (1983-1994)

The case records of 37 Newfoundlands with congestive heart failure caused by dilated cardiomyopathy were reviewed in an attempt to compare current knowledge of dilated cardiomyopathy with findings in a large and homogeneous population. The clinical diagnosis was based on echocardiographic findings of reduced shortening fraction (FS) in the presence of clinical and radiographic signs or necropsy findings of left-sided or biventricular heart failure. Systolic murmurs were detected in only four cases. Atrial fibrillation was the most common arrhythmia. Histopathological changes consisted of attenuated wavy fibers and interstitial fibrosis. No significant sex predilection was observed.

Canine Dilated Cardiomyopathy

The case records of 189 dogs (including 38 breeds) with congestive heart failure caused by dilated cardiomyopathy were studied retrospectively. Airedale terriers, boxers, Doberman pinschers, English cocker spaniels, Newfoundlands, St. Bernards, and standard poodles were over-represented. German shepherd dogs were under-represented. A male predominance was observed. Systolic murmurs were detected in 25% of the cases. Atrial fibrillation was the most common arrhythmia. Mild hyperglycemia and mild-to-moderate hypercholesterolemia were found in 38% and 33% of cases, respectively. Histopathological changes consisted of attenuated wavy fibers and interstitial fibrosis.

Balloon Ablation

A 70-year-old man who developed dilated cardiomyopathy with persistent atrial fibrillation (PSAF) was admitted to our hospital. He was already drug-resistant. The left atrium (LA) was severely enlarged. The left ventricular ejection fraction (LVEF) was 39%, and contraction was severely reduced. For AF ablation, catheter ablation (CA) was used for mild to moderate LV dysfunction without severe left atrial dilatation. In severe LV dysfunction, excessive intravenous drip volume may precipitate congestive heart failure. On the other hand, shorter isolation time has been reported with balloon ablation as compared to CA. Therefore, the intravenous drip volume is small. We planned to use the balloon technique for a patient with LA dilatation and severe LV dysfunction despite another hospital not having done so. After the procedure, the pulmonary veins were successfully isolated, and congestive heart failure recovered after sinus rhythm termination. There was no recurrence of AF after the procedure. Hot balloon ablation can be effective for PSAF with severe heart failure.

Electrocardiogram Ecg

In this paper, symbolic relative entropy was used to analyze normal electrocardiogram (ECG), the ECG taken from patient with congestive heart failure (CHF) and Atrial fibrillation (AF). Statistical testing showed that the symbolic relative entropy of normal ECG was distinctly higher than that of CHF while the symbolic relative entropy of CHF was distinctly higher than that of AF. It discoved that symbolic relative entropy can be used to analyze the different pathological ECG which could be used to assisted clinical diagnosis.
