  • Computed tomography (CT) plays an important supplementary role in the evaluation of patients with heart disease. CT can be used to evaluate the aorta, pulmonary artery, pulmonary vein, cardiac chambers, coronary artery, valves and systemic veins (superior vena cava, inferior vena cava and hepatic veins). The "Learning Objectives" describe the normal anatomy and typical pathological conditions seen on axial scans and reformatted images from CT in patients with heart disease, focusing focus on frequent, fatal, and rare but characteristic diseases encountered in routine practice.

  • The incidence of congenital aortic valvular stenosis has been known rare, and approximately 3-6% of congenital heart diseases. Recently, we experienced 1 case of congenital aortic valvular stenosis, and which was corrected surgically under extracorporeal circulation successfully. A 11 years old male pt. was admitted to N.M.C. because of dyspnea, dizziness, chest pain and episode of syncope. An auscultation, harsh systolic murmur [Gr. IV/VI] was noted at aortic area and also palpable strong thrill. ECG showed LVH c strain pattern and suspicious LVH finding in simple chest P-A film. In Lt. cardiac catheterization, abrupt pressure change [110mmHg] between LV & Aorta was noted across the aortic valve. And aortic insufficiency was absent, well visualized both coronary arteries and suspicious bicuspid aortic valve in aortography. Valve form was bicuspid, large one was noncoronary cusp and another cusp was Rt. & Lt. coronary cusp which was interpositioned rudimentary commissure. Central aortic orifice was about 5ram in diameter. Valvulotomy was done along the fusioned commissure between noncoronary cusp and Rt. & Lt.coronary cusp, and then short incision was added between Rt. coronary cusp & Lt. coronary cusp. Immediate postoperative course smooth but unknown cardiac arrest was noted in POD second day. Complete recovery was done without sequelae by resuscitation. After operation, clinical symptoms were subsided but systolic murmur [Gr. II/VI] was audible at aortic area, diastolic murmur was absent. ECG showed still remained LVH but much decreased R wave voltage in Lt. precordial leads. Simple chest P-A showed no interval changes compared to preop film. Control Lt. heart catheterization revealed still remained pressure gradient [40ramrig] between LV & Aorta. But much decreased pressure gradient compared to preop pressure gradient [110mmHg].

  • Lysyl oxidase (LOX) catalyzes the lysine-derived cross-links of fibrillar collagens and elastin in the extracellular matrix. Recent molecular cloning has revealed existence of a LOX family consisting of LOX and four lysyl oxidase-like proteins (LOXL, LOXL2, LOXL3 and LOXL4). Pathological conditions associated with impaired LOX activity in several heritable and acquired disorders lead to severe structural and functional abnormalities of cardiovascular tissues, such as occlusion of coronary arteries and aneurysms, suggesting an essential role for the LOX family proteins in the maintenance of the cardiovascular system. However, the specific roles of the lysyl oxidase-like proteins in normal and pathological conditions of the cardiovascular tissues have not been established yet. Here, I report that LOXL3, a novel member of the LOX family, is predominantly expressed in the aorta, with an amine oxidase activity toward collagen and elastin, suggesting an essential role of LOXL3 in the development and maintenance of the aorta.

  • Echocardiography and catheterization angiography suffer certain limitations in the evaluation of congenital heart diseases in adults, though these are overcome by MRI, in which a wide field-of view, unlimited multiplanar imaging capability and three-dimensional contrast-enhanced MR angiography techniques are used. In adults, recently introduced fast imaging techniques provide cardiac MR images of sufficient quality and with less artifacts. Ventricular volume, ejection fraction, and vascular flow measurements, including pressure gradients and pulmonary-to-systemic flow ratio, can be calculated or obtained using fast cine MRI, phase-contrast MR flow-velocity mapping, and semiautomatic analysis software. MRI is superior to echocardiography in diagnosing partial anomalous pulmonary venous connection, unroofed coronary sinus, anomalies of the pulmonary arteries, aorta and systemic veins, complex heart diseases, and postsurgical sequelae. Biventricular function is reliably evaluated with cine MRI after repair of tetralogy of Fallot, and Senning's and Mustard's operations. MRI has an important and growing role in the morphologic and functional assessment of congenital heart diseases in adolescents and adults.

  • 심혈관계 석회화는 다양한 심혈관계 질환에서 나타나며 심혈관 사건 발생의 표지자의 역할을 한다. CT의 기술이 발전함에 따라 심전도동기 CT뿐만이 아닌 비 심전도동기 CT에서도 심혈관계 석회화를 평가하는 것이 가능해졌다. 이번 종설에서는 비 조영증강 비 심전도동기 흉부 CT에서 발견되는 심혈관계 석회화를 심혈관 사건 발생과 연관되었다고 알려진 3가지 석회화(관상동맥, 흉부 대동맥, 판막 석회화)에 대해 자세히 살펴보고 추가적으로 우연적으로 발견될 수 있는 심막 석회화에 대해서도 간단히 기술하였다. 우리나라에서 2019년 하반기부터 폐암 검진이 시작되면서 고령 흡연자의 비 조영증강 비 심전도동기 저선량 CT의 영상의 수가 늘어나고 있고 이에 우연히 발견되는 심혈관계 석회화도 늘어나고 있다. 그러므로 비 조영증강 비 심전도동기 흉부 CT에서 발견되는 심혈관계 석회화의 의미를 이해하고 적절히 보고하는 것이 영상의학과 의사에게 중요할 것이다.

  • Background and Objective: Atherosclerosis is a diffuse, systemic disease that affects the coronary, cerebral, and peripheral arterial trees. Clopidogrel is widely used antiplatelet agent and its efficacy has been proven in cardiac and extracardiac vascular diseases, but it has several side effects. Therefore we investigated whether Sopunghwalhyeoltang, which is widely used for treating the blood stasis syndrome in traditional medicine, could decrease the side effect of antiplatelets and have a synergic effect. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups, non-treated group (Control group), clopidogrel-treated group (CP group) and clopidogrel with Sopunghwalhyeol-tang treated group (CPS group). The control group was fed with only an atherogenic diet, the CP group an atherogenic diet plus clopidogrel 25mg/kg and the CPS group an atherogenic diet plus clopidogrel 25mg/kg with Sopunghwalhyeol-tang 100 mg/kg. We investigated plasma lipids with liver function test, and performed a histological investigation of liver and abdominal aorta. Results: 1. Photomicrographs of liver and abdominal aorta tissue showed lower histological injury and lipid accumulation in the CP and CPS groups than those in the Control group. 2. In the CPS group, plasma triglyceride level was significantly lower than in the Control and CP groups. 3. In the CPS group, the plasma aspartate aminotransferase (AST) level was significantly lower than in the CP group. Conclusions: The above results shows that a combined treatment of Sopunghwalhyeol-tang and clopidogrel have a synergic effect through inhibiting vessel injury and decrease the side effects of clopidogrel alone.

  • 배경: 뇌관류 방법은 저체온 순환정지를 이용한 흉부 대동맥 수술 시 가장 중요한 관심사이다. 이 연구는 저체온 순환정지를 이용한 흉부 대동맥 수술 시 뇌관류 방법(역행성 뇌관류법과 전방성 뇌관류 법)에 따른 수술 결과를 비교하였다. 대상 및 방법: 1995년 5월부터 2007년 2월까지 저체온 순환정지를 이용한 흉부 대동맥 수술 중 역행성 뇌관류법이나 전방성 뇌관류법을 이용한 146명의 환자를 연구대상으로 후향적으로 분석하였다. 이 중 역행성 뇌관류법을 사용한 경우가 114예(1군)였으며 전방성 뇌관류법은 32예(2군)에서 사용되었다. 원인별로는 대동맥 박리증이 104명(급성 박리증 94명, 만성 박리증 10명), 대동맥류가 42명(진성 대동맥류 41명, 가성 대동맥류 1명)이었다. 수술 범위로는 대동맥궁 완전치환술 21명, 대동맥궁 부분치환술 5명, 대동맥궁 반치환술을 33명에서 시행하였으며 모든 환자에서 상행대동맥 치환술을 시행하였다. 결과: 두 군간의 수술 전 혹은 수술 특성은 대부분 비슷하였지만 2군에서는 70세 이상 고령 환자가 더 많았으며(34.4% vs. 10.5%), 관상동맥 질환이 더 많았고 (18.8% vs. 4.4%), 대동맥궁 완전치환술을 더 많이 시행하였고 (46.9% vs. 5.3%), 저체온 순환정지 시간이 더 걸었다 ($50{\pm}24$분 vs. $32{\pm}17$분). 수술 사망률은 1군이 4.4% (5/114)였고 2군이 3.1% (1/32)였다. 영구적 뇌손상 발생률은 1군이 5.3% (6/114)였고 2군이 3.1% (1/32)였다. 일시적 뇌손상은 1군이 1.8% (2/114)였고 2군이 9.4% (3/32)였다. 수술 사망률, 수술 후 출혈 및 뇌손상(영구적 혹은 일시적) 발생률은 두 군간 통계적 유의성이 있는 차이는 보이지 않았다. 결론: 저체온 순환정지를 이용한 대동맥 수술의 조기 결과는 양호하였고 뇌관류법에 따른 차이는 관찰되지 않았다. 하지만 저 체온 순환정지 시간이 더 길거나 더 광범위한 대동맥궁 수술에서 전방성 뇌관류법이 이용되었음에도 불구하고 대등한 결과를 보인 점을 고려할 때 저체온 순환정지 시간이 걸어질 것으로 예상되거나 수 술범위가 커질 것으로 예상되는 경우에는 전방성 뇌관류법을 사용하는 것이 바람직할 것으로 사료된다.
