Aortic regurgitation is not a rare complication of Takayasu's disease. Aortic regurgitation may aggravate cerebral ischemic syndrome like syncope in patients with stenotic or occlusive lesions in cerebral branches of aorta secondary to acute or progressive inflammation. In a 34-yrs-old male patient who complained of syncope and exertional dyspnea with occlusion of both carotid arteries and severe stenoses of both subclavian arteries, occlusion of right coronary artery, and aortic regurgitation, his symptom was improved with perioperative aggressive steroid therapy, stent insertion in both subclavian arteries, and aortic valve replacement.

Fructus Aristolochiae has been used in Korea for many centuries as a treatment for various disease.The purpose of the present study is to determine the effect of Fructus Aristolochiae on norepinephrine(NE) induced blood vessel contraction in rabbits. Rabbit(2 kg, male) were killed by $CO_2$ exposure and a segment (8-10mm) of each rabbit was cut into equal segments and mounted in a tissue bath. Contractile force was measured with force displacement transducers under 2-3 g loading tension. The dose of norepinephrine(NE) which evoked 50% of maximal response ($ED_{50}$) was obtained from cumulative dose response curves for NE ($10^{-6}{\sim}10^{-3}M$). Contractions evoked by NE ($ED_{50}$) were inhibited significantly by Fructus Aristolochiae in abdominal aorta and femoral artery. Fructus Aristolochiae inhibited the relaxation pretreated propranolol and L-NNA in femoral artery. But Fructus Aristolochiae did not effect the relaxation pretreated ODQ in femoral artery and abdominal aorta. These results indicate that Fructus Aristolochiae can relax NE induced contraction of rabbit blood vessel selectively, and that this relaxation relates to nitric oxide synthesis and sympathetic action.

Noninfectious aortitis, inflammatory abdominal periaortitis, and idiopathic retroperitoneal fibrosis are chronic inflammatory diseases with unclear causes. Recent studies have shown that some cases of aortitis are associated with immunoglobulin G4 (IgG4)-related systemic disease. Herein, we report a case of IgG4-related aortitis (IgG4-RA) that was diagnosed after surgery. Our patient was a 46-year-old man who had experienced abdominal pain for several weeks. Preoperative evaluations revealed an area of aortitis on the infrarenal aorta. He underwent surgery, and histological examination resulted in a diagnosis of IgG4-RA.

Shone complex is a rare congenital disorder that involves 4 obstructive lesions of the left heart, as follows: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta. Incomplete forms with 2 or 3 of these lesions in adult patients have been rarely reported in the literature, meaning that insufficient general data exist concerning the surgical strategy and clinical follow-up. Herein, we report the case of a 31-year-old woman with a diagnosis of incomplete form of Shone complex with parachute mitral valve and coarctation of the aorta who underwent successful single-stage surgical repair.

Congenital Cystic Lung Disease is a spectrum of closed related anomalies that arise during an early stage of embryonic lung bud maturation-namely bronchogenic cyst, congenital lobar emphysema, pulmonary sequestration and congenital cystic adenomatoid malformation. And they show similar surgical strategies. So they are called as the term bronchopulmonary-foregut malformations, firstly proposed by Gerle[1968]. From Aug. 1979 to Aug 1989, 47 patients were operated upon on Dept. of Thoracic & Cardiovascular Surgery at the CUMC. There were 21 females and 26 males ranging in age from age of 21 day to age of 56 year [15 cases under 15 years old]. 30 patients had bronchogenic cysts - 23 of intrapulmonary type, 7 of mediastinal type in location. Affected lobes and locations were as follows: 11 in upper lobe, 3 in middle lobe, 11 in lower lobe and anterosuperior, middle, and posterior mediastinal type were 3, 2, 2 respectively. There were 9 pulmonary sequestrations[all intralobar type] with the distribution of 5 in right lower lobe and 4 in left lower lobe. And associated anomalies were presented with arterial supply originating from thoracic aorta[8 cases], abdominal aorta[1 case] and with venous drainage into azygos vein[1 case]. They all were operated upon lower lobectomy [8 case], pneumonectomy[1 case] in case of pulmonary hypoplasia Congenital lobar emphysema and congenital cystic adenomatoid malformation had 4 cases respectively. Their affected lobes were as follows: the former were 3 in upper lobes, 1 in middle lobe and the latter were 3 in upper lobe, 1 in lower lobe. They were treated with lobectomy and segmentectomy. Diagnosis was aided by chest X - ray, bronchography, aortography, DSA and CT scan, They all were confirmed by pathologic exams. There were no hospital death but few minor morbidities such as, atelectasis-pneumonia[2], wound infection[2], prolonged chest tube placement[2]. We experienced surgical treatments of 47 cases for 10 years and reported them with literature review.

This study aimed to evaluate the plasma concentration of NT-proBNP in dogs with different stages of heart failure by chronic mitral valve insufficiency (CMVI). Fifty small-breed dogs with CMVI and 7 healthy control dogs without cardiac disease and critical systemic diseases were included in the study population. As a preliminary study, we compared the plasma concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP) and the echocardiographic parameters between dogs of the International Small Animal Cardiac Health Council (ISACHC) classes. Then, we evaluated the associations between NT-proBNP and echocardiographic parameters. Plasma NT-proBNP levels showed a significant difference among the ISACHC groups. In the comparison between echocardiographic parameters and NT-proBNP, NT-proBNP were found to be associated with left atrium/aorta (LA/AO), early diastolic transmitral flow (E) velocity, late diastolic transmitral flow (A) velocity, end diastolic volume index (EDVI). Our study found plasma NT-proBNP might be useful to predict the disease progression in dogs with CMVI.

Takayasu's arteritis(aortoarteritis) is a chronic inflammatory disease involving the aorta, the arteries arising from the aorta, and the pulmonary arteries also may be involved. The inflammation leads to either stenosis and occlusion of the involved artery or formation of aneurysm or both. The arterial lesions can lead to secondary hypertension, retinopathy, cardiac involvement, cerebrovascular events, and premature death. The course and prognosis of patients with aortoarteritis show wide variation, and few authors have published systematic studies documenting the natural history of this disease. While the etiology of Takayasu's arteritis remains unknown, various modes of treatment including steroids, vascular surgery, and balloon angioplasty have been used for management of these patients. We experienced a case of Takayasu's arteritis with multiple occlusion of pulmonary arteries, which was confirmed by angiography and perfusion scan, so reported it with a review of literature.

Purpose: Coronary arterial lesion assessment in children can be difficult, depending on the coronary dominance pattern. Although it is easier to determine coronary dominance with echocardiography in children than in adults, it is still difficult. This study aimed to examine the coronary dominance pattern according to the objective coronary artery (CA) indices. Methods: The CA diameter, aortic valve annulus, and abdominal aorta of 69 children without any cardiovascular disease were measured with cross-sectional echocardiography at Chungnam National University Hospital. To evaluate the coronary dominance pattern, echocardiography was primarily used; additionally, coronary computed tomographic angiography or coronary angiography (CAG). Coronary dominance was determined according to the status of the CA that gives rise to the posterior descending artery. Results: The mean age was $4.02{\pm}2.78years$, and the mean body surface area (BSA) was $0.70{\pm}0.22m^2$. Right dominance was present in 78% and left in 22% of the subjects. In those with left dominance, the CA to aortic valve annulus diameter ratio was $0.125{\pm}0.021$ in the right coronary artery (RCA) and $0.255{\pm}0.032$ in the left coronary artery (LCA). In those with right dominance, the corresponding ratio was $0.168{\pm}0.028$ in the RCA and $0.216{\pm}0.030$ in the LCA (P<0.05). Significant differences were also found in the diametric ratios of the CA to BSA and abdominal aorta (P<0.05). Conclusion: The CA indices showed significant difference according to the coronary dominance pattern in early childhood. It is possible to indirectly determine the coronary dominance pattern with the CA indices in children using echocardiography. The accuracy of coronary artery lesion diagnosis can be improved by taking coronary dominance into account.

The causes of vocal cord paralysis include iatrogenic injury during thyroid or cervical surgery, heart and chest surgery, and tumorous lesion such as laryngeal cancer and lung cancer. In addition to these common causes, rarely, cardiovascular disease can also cause vocal fold paralysis. A disease known as Cardiovocal syndrome, or Ortner's syndrome, causes left vocal fold paralysis when the left recurrent laryngeal nerve is compressed by the pulmonary artery and aorta, which is occurred by pulmonary hypertension from heart disease. We report for the first case in Korea the diagnosis of vocal fold paralysis caused by Ortner's syndrome.

The purpose of this study is to evaluate an effectiveness of switching turbo direction to improve motion artifacts of small bowels and aorta. From June to October 2015, 60 patients suspected of having Crohn's disease were enrolled. The MR Enterography scans were performed using same protocol other than the turbo direction: with the Z phase encoding (group A) and with Y phase encoding (group B). Qualitative analysis of each group was performed to evaluate the effectiveness of switching turbo direction from Z to Y. As a result, the 5-point Likert scale for paired observers were $2.33{\pm}0.88$ for group A and $3.80{\pm}0.85$ for group B on dynamic contrast enhanced coronal images. In conclusion, group B is proved to be superior to group A and can lessen the motion artifacts derived from phase shifts.
