Amiodarone is an iodinated benzofuran derivative that has been proved effective in the control of supraventricular and ventricular arrhythmias refractory to other antiarrhythmic drugs. In patients treated with amiodarone, subsequent surgical intervention is a common clinical scenario, but unfortunately we do not have definite data about complications due to amiodarone after cardiac surgery. Some reports have shown that amiodarone treatment can be associated with a state of $\alpha$-adrenergic and $\beta$-adrenergic receptor blockade, which requires more pacing and epinephrine infusion for perioperative hemodynamic support. And some reports have also identified a severe form of ARDS in patients on amiodarone therapy which was associated with siginificant morbidity and mortality. We exprienced a patient who expired after mitral valve replacement due to amiodarone-induced ARDS; therefore, we report this case with a brief literature.

We are now detecting an increasing number of solitary pulmonary nodules (SPNs) that are difficult to diagnosis. The purpose of this study was to evaluate the useful radiologic findings for differentiating benign from malignant pulmonary nodules. Material and Method: The high-resolution CT (HRCT) findings of SPNs smaller than 3 cm in largest diameter were evaluated in 134 patients with malignant and benign nodules in regard to internal structures, margin characteristics, and surrounding parenchymal responses. Result: The nodules with the area of ground-glass attenuation (GGA) greater then 50% were noted in adenocarcinoma, inflammatory lesions and some of metastatic tumors, and the lesions greater than 90% were noted only in adenocarcinoma. The area of GGA in non-adenocarcinoma, benign tumors and tuberculomas were less than 50%, and mainly less than 10%. The findings of air bronchogram, spiculation, lobulation, vascular involvement, and pleural indentation were some noted at every types of malignant tumors, but especially high over than 30% in adenocarcinomas. Conclusion: Most peripheral lung adenocarcinomas form a characteristic radiologic findings especially in HRCT. Evaluation of these findings would be helpful in differentiating between lung cancer, especially adenocarcinoma, and other lesions.

Deep vein thrombosis (DVT) is a common disease. However, May-Thurner syndrome, which is the cause of DVT, is an uncommon processes in which there is an impaired venous return due to compression of the left iliac vein by the overlying right common artery. This condition results in a left iliofemoral deep thrombosis and severe leg edema. It is, therefore, called iliac compression syndrome. Catheter-directed thrombolytic therapy of acute extensive iliofemoral DVT and balloon angioplasty with venous stenting are recommended. Two cases with history of left leg swelling are diagnosed as May-Thurner syndrome, which was demonstrated by venography. We successfully treated the patients with thrombolysis, balloon angioplasty, and stent insertion at the site of common iliac vein compression. Therefore, we report the cases with overall review of the literature.

Congenital cystic adenomatoid malformation of the lung is a rare pulmonary malformation, Although it is one of the most common congenital anomalies which cause acute respiratory distress in the newborn infants, characterized by marked proliferation of terminal respiratory structures. We have experienced an unusual case of congenital cystic adenomatoid malformation associated with pectus excavatum. The patient was 3-year-old female who suffered from cough and high fever for 20 days, and antibiotic therapy was given in other hospital before transfer to our hospital. The findings on chest X-ray, chest CT, aortogram, and selective bronchial arteriogram showed cystic lesions in the right upper and middle lobe accompanied but severe pectus excavatum. Right bilobectomy for pulmonary lesion and costosternal elevation for pectus excavatum was performed simultaneously with successful result. The postoperative course was uneventful and the patient was discharged on the twentieth postoperative day.

Although mediastinal involvement by Hodgkin's disease is frequent, the initial presentation of the lymphoma by an endobronchial lesion is rare. A 23-year-old man was admitted with progressive dyspnea. Initial chest roentgenogram showed atelectasis of right middle and lower lobe. Fiberoptic bronchoscopy showed a polypoid mass obstructing the right mainstem bronchus. The mass lesion was histologically confirmed as Hodgkin's disease, nodular sclerosis type. He received systemic chemotherapy and improved rapidly.

Myxomas are the most common form of intracardiac tumors and are found primarily in the left atrium. In rare cases, Carney and associates have described a syndrome called "the complex of myxoma" consisting of cardiac myxoma, which characteristically is familial, in assocation with two or more of the follow conditions: myxomatous masses (cardiac myxoma, cutaneous myxosma, and mammary myxoid fibroademoma), spotty pigmented lesions of the skin, and endocrine disorders. We report a case of familial atrial myxoma with Carney's complex in a 19-year old woman who has spotty pigmentations on her face, and left atrial myxomas, and myxoma on the right nipple. Her mother and sister share the left atrial myxoma. The myxomas originated in the septum of the left atrium and the anterior leaflet of the mitral valve were successfully excised. In conclusion, family members of affected patients should be screened periodically with echocardiography in an attempt to identify asymptomatic cardiac myxomas. Complete excision and postoperative follow up are necessary to rule out the muticentricity and high rate of recurrent lesions.

Organ malperfusion may mask the presence of aortic dissection and is one of major cause of death in patient with aortic dissection. Several key mechanism appear to contribute to the development of malperfusion, therefore optimal choosing of treatment is necessary to obtain better result. In cases of extremity malperfusion, open bypass procedures have been used for primary treatment, but noninvasive interventional procedures are also recommended as good alternatives in some cases. Here in, we report a case of successful aortic replacement followed by stent insertion in patient with extremity malperfusion caused by acute aortic dissection.

Pulmonary hyalinizing granuloma (PHG) is a rare disease that usually presents with multiple bilateral pulmonary nodules and characteristic histological findings, with hyaliuized collagen lamellae. Because of the absence of characteristic radiologic and clinical features, PHG is usually diagnosed after surgical resection or biopsy. We performed thoracoscopic wedge resection for a pulmonary nodule located in the right lower lobe that proved to be PHG histo-pathologically. We report two cases along with a review of the literature.

Patients with aortic root disease, frequently seen in Marfan syndrome have progressive dilatation of the aortic sinuses and dilatation and distortion of the aortic annulus, leading to aortic incompetence. They are currently treated with composite graft replacement of the ascending aorta and aortic valve and reimplantation of the coronary arteries. Recently, we experienced an aortic root replacement with aortic valve preservation in a patient with annuloaortic ectasia. The ascending aorta and sinus was excised except the aortic annulus and aortic valve. The aortic valve was reimplanted inside of a collagen-impregnated tubular Dacron graft. The coronary arteries were also reimplanted. The patient was followed up for six months and reevaluated with the echocardiography. Postoperative Doppler echocardiography revealed normal aortic valve function. With this technique, it is possible to preserve the native aortic valve if the aortic leaflets are anatomically normal.

Ventricular septal defect (VSD) complicating an acute myocardial infarction is rather uncommon. However, the outcomes after the development of a VSD are poor with an in-hospital mortality of more than 90% for the medically treated patients. To prevent the recurrence of VSD, many techniques have been reported on for the closure of a postinfarction VSD. In this. report, we present a case of a patient who had a postinfarction VSD due to Prinzmetai's variant angina, and the rupture of the pseudoaneurysm of the left ventricle was successfully treated by the "Sandwich technique".
