We experienced an intraatrial baffle repair for unroofed coronary sinus syndrome in TOF. The patient was a 32-month old female, with complaints of cyanosis, exertional dyspnea and growth retardation. Physical examination showed cyanosis of lip, clubbing of finger, growth retardation and systolic murmur[0 /Gr VI] on left sternal border. With an aid of noninvasive and invasive diagnostic procedure, the patient was diagnosed as TOF combined with unroofed coronary sinus syndrome and LSVC connecting to left atrium. After patch closure of VSD, infundibulectomy and pulmonary valvotomy, the intraatrial baffle redirection of anomalous LSVC to right atrium was undertaken. The Dacron baffle was constructed along the roof of the left atrium to the plane of the atrial septum. The intraatrial septum was then reconstructed with Dacron which was sutured to residual septal tissue. After surgery, the systemic oxygen saturation was elevated to 95.5%, as compared with preoperative value 61%. The postoperative course was uneventful.

A technique applicated for physiologic correction of complex congenital cardiac disease suitable for Fontan procedure in which drainage of left superior vena cava and hepatocardiac vein to left atrium combined is described. We made one systemic venous baffle from left hepatocardiac vein to left superior vena cava and another systemic venous baffle from right inferior vena cava to the right superior vena cava with rigid prosthetic material[0.5mm thickness PTFE patch]. And then we anastomosed directly between the right sided atrial appendage and right pulmonary artery, and left-sided atrial wall beneath the appendage and left pulmonary artery. We believe that this procedure is superior to the method using intraatrial tube graft to divert the left hepatocardiac venous blood to right atrium, and applicable for physiologic correction of any complex congenital cardiac disease suitable for Fontan-type procedure in which anomalies of systemic venous drainage combined.

The usage of autosuture instruments and techniques in resection of bronchovascular structures gained increasing acceptance amongst surgeons in the recent years. The manipulation of these devices are simple, safe, and shortens operating time by avoiding numerous ties and sutures. We have been using autosuture instruments in most of pulmonary resections in Yongdong Severance hospital, and had a satisfactory results. However, we recently have experienced post-pneumonectomy rupture of left pulmonary vein on postoperative one day where the rupture site was in the border of left atrium and left pulmonary vein where the stapler was fired. The patient underwent emergency operation to control massive bleeding and successfully managed by left atrial suture.

This study analysed the factors that predict and influence heart disease through key indicators related to changes in left atrial and left ventricular size. Measurements recommended by the American Society of Echocardiography were used, and the influence of variables was assessed using multiple regression analysis. The results showed that left atrial volume index(LAVI) was significantly different by age, obesity, diabetes, hypertension, dyslipidaemia, and left ventricular relaxation dysfunction(p<0.05). Left ventricular mass index(LVMI) was significantly different according to age, body mass index, hypertension, diabetes, dyslipidaemia, and left ventricular relaxation dysfunction(p<0.05). Increases in LVMI and relative ventricular wall thickness(RWT) were associated with changes in LAVI(p<0.05). Age, systolic blood pressure, increased LAVI, and RWT influenced changes in LVMI, and left ventricular dysfunction was analysed as an influencing factor for both changes in LAVI and LVMI. Therefore, changes in left atrial and left ventricular size are indicators for early diagnosis and prevention of heart disease, and it is necessary to carefully observe structural changes in the heart and actively manage risk factors for the prevention and management of heart disease.

Primary cardiac tumors are very uncommon. Seventy five percent of them are benign tumors and these are mostly myxomas. The malignant cardiac tumors, the majority of which are undifferentiated sarcomas, comprise up to 25% of all cardiac tumors. A primary malignant sarcoma of the myocardium is exceedingly rare. Thus, there have been very few such cases reported in the literature. We present here a case of a 15 year old man who had complaints of orthopnea and increasing exercise intolerance over a one month period. Transthoracic echocardiography demonstrated a well demarcated huge mass with left ventricular inflow obstruction on the posterior wall of the left atrium. The patient's symptoms were relieved by surgery. The histological diagnosis was an unclassified spindle cell sarcoma.

Surgical treatment of partial endocardial cushion defect was accomplished in Feb. 1984 in this department. The 5 year old male patient had history of frequent upper respiratory tract infection and since his age of 3 years dyspnea on exertion and palpitation were noted but there were no cyanosis and clubbing. A thrill was palpable on the apex and grade IV/IV harsh systolic ejection murmur and diastolic murmur was audible on it. Liver was palpable about 3 finger breadths and no ascites. Chest X-ray revealed increased pulmonary vascularity, moderate cardiomegaly [C-T ratio; 0.69], and enlarged left atrium. EKG showed first degree heart block, RVH, LVH, and LAD. Echocardiogram showed paradoxical ventricular septal movement and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted left to right shunt [Qp:Qs:2.1:1 ] and moderate pulmonary hypertension [60/40 mmHg]. Left ventriculogram showed mitral regurgitation [Grade III/IV] and filling of left atrium and right atrium nearly same time. Operative findings were: 1.Primum type atrial septal defect [3x2 cm] 2.Cleft on the anterior leaflet of mitral valve. 3.No interventricular communication and cleft of tricuspid valve leaflet. The mitral cleft was repaired with 4 interrupted sutures. The primum type atrial septal defect was closed with Dacron patch intermittently at endocardial cushion and continuously remainder. The post operative course was uneventful and discharged on 22nd postoperative day in good general conditions.

We present a case of a 55-year-old woman who complained of chest pain at rest. A mass was detected adjacent to her left atrium. The mass was completely excised, and a pathologic examination revealed it to be a schwannoma. Schwannomas are tumors that originate in the nerve sheath and are rarely detected in the heart. Here, we describe a rare case of primary schwannoma of the left atrium.

A fistula between the right pulmonary artery and the left atrium is a very rare congenital anomaly, for which there is no definitive embryogenetic explanation. Patients present with cyanosis or clubbing, and the treatment strategy is to close the fistula, which can be done by an open surgical technique or by percutaneous intervention. Although rare, this condition should be considered in the differential diagnosis when evaluating a patient with central cyanosis.

In this study, we simulated the atrial arrhythmia numerically. By using electro-physiological model of atrial cell from Nygren et al. and applying reaction-diffusion partial differential equation, we simulated electrical conduction in atrium. A 3-D mesh system representing the human atrium was reconstructed from the surface geometry of atrium. We used a stimulus in the form of an archetype around pulmonary vessels in the left atrium to cause the atrial arrhythmia. The septal atrial tarchycardia was developed after the stimulus.

We report a case of invasive pulmonary aspergillosis invading the mediastinum and the left atrium. A 70-year-old woman was hospitalized for dyspnea. She had been well controlled for her diabetes mellitus and hypertension. The chest X-ray disclosed mediastinal widening, and the computed tomography scan of the chest showed that there was a large mediastinal mass and this lesion extended into the left atrium and right bronchus. The cardiac echocardiography showed that a huge mediastinal cystic mass compressed in the right atrium and a hyperechoic polypoid lesion in the left. The pathology from the bronchoscopic biopsy observed abundant fungal hyphae which was stained with periodic acid-Schiff and Gomori's methenamine silver. Despite the treatment with antifungal agents, she died from cardiac tamponade after three months. Invasive pulmonary aspergillosis, which involves the mediastinum and the heart, is very rare in immunocompetent patients.
