A 6-month-old intact male Maltese dog (2.5 kg of body weight) was presented with the primary complaint of heart murmur and exercise intolerance. Diagnostic studies revealed severe pulmonic stenosis. Since the pressure gradient in stenotic pulmonic valve area was higher than 200 mmHg (maximum flow velocity = 7.1 m/s), the dog was underwent balloon valvuloplasty. With this procedure, the peak pulmonic velocity was reduced to 3.0 m/s (PG = 36 mmHg). Periodic re-evaluations performed in monthly interval revealed no further deterioration even after 4 month of procedure. This is the first case report of pulmonic stenosis fixed by non-surgical balloon valvuloplasty in Korea.

A 6-month-old mature intact female Siamese cat presented with exertional dyspnea. Diagnostic studies revealed pleural effusion, grade 4/6 left basal systolic murmur, deep S-wave in electrocardiograph leads I, II, and III, cardiomegaly with pleural effusion on radiography, pulmonic systolic (~5.8 m/sec) and tricuspid (3.6 m/sec) regurgitant jets, atrial septal defect, and a hypoplastic right outflow tract. Based on these results, the case was diagnosed as pulmonic stenosis with atrial septal defect. To the best of our knowledge, this is the first case report describing pulmonic stenosis with atrial septal defect in a cat in Korea.

A 1.3 year-old Castrated male Bedlington terrier (10.0 kg of body weight) was presented with heart murmur and occasional coughing. Diagnostic imaging studies revealed supravalvular pulmonic stenosis (maximal velocity 2.91 m/s) from abnormal membranous structure (aperture) distal to the pulmonary valve in the main pulmonary artery. Further study also revealed pulmonic regurgitant (1.82 m/s of peak velocity, 13.2 mmHg of pressure gradient) jets started from the abnormal membranous structure. Since the dog had no obvious clinical signs related to heart failure, no interventional therapy including balloon dilation was considered in this case. Instead, medical treatment for preventing further deterioration of clinical signs related to PS was done with enalapril. This case report described a rare case of type III supravalvular PS in a dog, which has never been reported. Further deterioration of clinical signs has yet been recognized after medical treatment.

A 3-year-old, intact female, Shih-tzu dog was presented with a 15-day history of vomiting,depression, and anorexia. On physical examination, systolic ejection murmurs with precordial thril atthe left heart base were detected. A diagnosis of congenital pulmonic stenosis (PS) was made mainlyfrom the thoracic radiography, electrocardiography, and echocardiography. On complete blood counts andconfirmed that main pulmonary artery was tremendously buldged and electrocardiography was suggestiveof severe right ventricular hypertrophy. Echocardiographic findings revealed the pulmonic valve stenosiscontaining valvular dysplasia and poststenotic dilation. On Doppler echocardiography, ejection velocityof the lesion accounted for 3.38 m/sec, meaning mild velocity through the stenotic area. The dog'sproblem and resulted in death. However, there has been no reliable relation between PS and CRF. Primarymalformation of pulmonic valve was confirmed at necropsy after death.

Congenital cystic disease of the lung is very rare and controversial disease. But in general is regarded as developmental anomaly. Occasionally failure of the primitive lung bud to develop combined with cardiac anomaly had been reported but it was very rare. Recently a case of cystic lung disease combined with pulmonic valvular stenosis was seen in this clinic with clinical pictures of nonspecific respiratory infection and X-ray finding very similar to that of far advanced pulmonary tuberculosis, destroyed left lung. This case was treated by closed pulmonic valvulotomy and left side pneumonectomy successfully.

An 8-year-old spayed female Maltese (2.5 kg of body weight) presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging revealed severe pulmonic stenosis (peak velocity 5.2 m/s) with right ventricular hypertrophy. The dog revisited after 2 years, at which time, diagnostic imaging revealed severe biventricular hypertrophy, dynamic left ventricular outflow tract obstruction, left atrial dilation and pulmonary hypertension with worsened pre-existing pulmonic stenosis. Postmortem investigation revealed hypertrophic cardiomyopathy and regional myocardial infarction. The case was diagnosed as hypertrophic cardiomyopathy secondary to severe right and left ventricular outflow tract obstruction.

The results of surgical experience of double outlet right ventricle with pulmonic stenosis in 14 patients are reported. Among the 14 patients, 8 underwent the intraventricular tunnel repair with the result of 3 hospital deaths, 5 had Fontan type operations due to the various anatomic reasons and resulted in one hospital death, and the remaining one patient had palliative pulmonary valvotomy. Besides the problems related to the effective relief of the pulmonic stenosis, double outlet right ventricle with pulmonic stenosis may present a surgical challenge because severe associated anomalies which definitely complicate their repair are not uncommon. We describe the anatomic details of our 14 cases of DORV with PS and the surgical results. The results having been unsatisfactory, more meticulous diagnostic studies for the detailed intracardiac morphologies and the strict indication for their repair with the refinement of surgical technique seem necessary for the better surgical results.

9개월령 프렌치불독(체중 13 kg)이 심한 심잡음과 운동불내성으로 내원하였다. 영상진단검사상, 폐동맥에서 5 m/s이상의 고속의 젯트와 우심실 비대가 확인되었다. 우심실과 유출로 사이의 압력구배가 100 mmHg이상이여서 풍선확장술로 치료하였다. 치료후 폐동맥에서 젯트속도는 2.1 m/s (PG = 18 mmHg)이하로 감속되었다. 환자는 그 이후에 별다른 진단검사상 악화소견이 관찰되지 않았다. 본 증례는 대퇴정맥으로 폐동맥 협착을 풍선확장술로 치료한 국내 첫 증례이다.

A 8-month-old female Maltese dog was presented with a history of heart murmur. In physical examination, grade 4/6 systolic murmur heard at the left heart base. Electrocardiography showed sinus arrhythmia, right axis deviation, deep S wave and splintered QRS complex. Thoracic radiography revealed enlarged right side heart and bulging of the main pulmonary artery. Echocardiography showed mild hypertrophy of right ventricle, a supravalvular stenosis, marked post-stenotic dilation of the main pulmonary artery and a moderately increased pulmonary arterial velocity through the stenotic area (4.4 m/s, pressure gradient of 78.7 mmHg). The dog was diagnosed with supravalvular pulmonic stenosis based on the diagnostic imaging findings. Medical management using ${\beta}1$-blocker and ACE inhibitor was started in this dog and this is first case report described diagnostic characteristic features of supravalvular pulmonic stenosis in korea.
