The aim of this study is to report the observed elevation of plasma N-terminal pro-B-type natriuretic peptide (NT proBNP) concentration in a Korean Jindo Dog infected with Dirofilaria immitis. Evaluation of the animal included physical examination, thoracic radiography, ELISA kit ($PetCheck^{(R)}$, IDEXX Laboratories, USA) test and plasma NT-proBNP evaluation. The infected animal's NT-proBNP concentration was compared with those of 5 normal dogs of the same age, sex, and breed; the affected Korean Jindo dog had increased plasma NT-proBNP. To the best our knowledge, this is the first report of NT-proBNP elevation in a Korean Jindo dog with dirofilariasis.

A 5-year-old, intact male Beagle was presented with chronic abdominal pain. The dog was diagnosed with dirofilariasis by positive heartworm antigen detection via ELISA and concurrent microfilaria. Thoracic radiographs revealed cardiomegaly with dilation of the main pulmonary artery. Echocardiography revealed the adult worms in the main pulmonary arteries, but other abnormalities other than heartworm infection were not present. To find the cause of the abdominal pain, exploratory laparoscopy was performed. Ectopic migrating adult heart worms were visualized through exploratory laparoscopy and the clinical sign resolved after removing the heart worm. This report describes removing the ectopic migrating adult heartworms using exploratory laparoscopy in the abdominal cavity.

This study was performed to assess the efficacy of surgical treatment with flexible alligator forceps (FAF) on heartworm infected dogs. Twenty dogs (10 males and 10 females) with heartworm infection, age $5.3\pm3.0\;(mean{\pm}S.D.)$ years and weight $9.3\pm6.5(mean{\pm}S.D.)kg$ were treated with FAF. Adult heartworms were removed by fluoroguided technique with FAF under inhalation anesthesia with isoflurane. For evaluation of the efficacy, removal rate and surgical time were measured, and removal sites were found. Antigen ELISA kit test and autopsy were performed to examine remained adult heartworms. Removal rate of total heartworms was $91.4\%$ including 15 complete retrieval cases and surgical time was $30.0\pm7.6(mean{\pm}S.E.)$ minutes. Heartworms were removed from the right ventricle, main pulmonary artery, and right and left pulmonary artery. Surgical treatment with FAF is an effective method with high removal rate, short surgical time, and various removal sites and it could be considered for the removal of adult heartworms in a dog.

Heartworm infection is a fatal disease causing heart failure and pulmonary diseases in dogs. This heartworm infection can also occur in wild carnivores including Raccoon dogs. Recent study found that relatively high prevalence rate in wild Raccoon dog population. Therefore, this study was designed to evaluate the prevalence rate of D. immitis in free-roaming Raccoon dogs and the recovery rate of microfilariae in infected Raccoon dogs in Korea. Overall prevalence rate of D. immitis in Korean Raccoon dogs was 17.8%. Prevalence rate in male Raccoon dogs was 21.8%, while that in female Raccoon dogs was 12.8%. Microfilariae were not detected in 17 Raccoon dogs having positive in heartworm antigen test. Our study result suggested that the prevalence rate of D. immitis in Korea is twice higher than that of Japan. In addition, microfilaremia is rare in Raccoon dogs as commonly noticed in cats.

Caval syndrome is a life threatening condition caused by heavy worm burden in right cardiac chambers including right atrium, right ventricle, and vena cava and results in mechanical interference in tricuspid valvular excursion and blood flow to lower pulmonary arteries. A mechanical worm removal is the choice of option for treating this condition in dogs. In this study, we developed a new mechanical worm removal method using modified extraction brushes for treating dogs with caval syndrome. With this newly developed method, we successfully removed heartworms in two dogs with caval syndrome. Although the number of cases applied was small, authors found this method can be a good alternative retrieval method for mechanical worm removal in dogs.

A 3-year-old intact female Dachshund was referred due to paraplegia and cool extremities. History taking, physical examination, neurological examination, and blood profiling studies were evaluated to determine the diagnosis. Based on abdominal ultrasound and echocardiograph, features suggestive of adult heartworm were detected in aberrant places. The result of enzyme-linked immunosorbent assay (ELISA) testing with a commercial heartworm antigen kit was positive. The dog fell into a comatose state, and the client requested the dog be euthanized. On post-mortem examination, the patient was diagnosed with ectopic parasitism of heartworm in the left side of heart, aorta, aorta abdominalis, and iliac arteries, a circumstance that induced systemic thromboembolism. This case report describes the clinical, diagnostic imaging, and necropsy findings of canine ectopic parasitism of heartworm.

Ancylostoma caninum과 Ancylostoma tubaeforme는 각각 개와 고양이에서 가장 병원성이 높은 구층(hookworm)이다. 현재 사용하는 두가지의 심장사상충 예방약이 개의 구충의 구제에도 효과가 있다. Ivermectin을 분만전후에 높은 용량으로 주사하면 Ancylostoma caninum의 유충이 모유를 통해 강아지에게 감염되는 것을 막을 수 있다.

A 7-year-old intact male Pitbull terrier dog was presented with complaints of marked abdominal distension and severe exercise intolerance. Diagnostic studies found a right-sided cardiomegaly with marked dilation of pulmonary arteries, diffuse interstitial pulmonary infiltration and heavy worm burden in the right atrium and ventricle. Color and spectral Doppler echocardiography also revealed tricuspid and pulmonic regurgitation indicating severe pulmonary hypertension. The 104 heartworms were removed by interventional extraction using a loop snare (Snare, Boston Scientific, USA) through external jugular vein. After heartworm removals, the clinical condition of this dog was remarkably improved. To author's best knowledge, this is the first case of interventional heartworm extraction using a loop snare in Korea.
