For the purpose of clinical analysis of secundum atrial septal defect, the patients with atrial septal defect operated on during the period from Aug. 1959 to Aug. 1983 were analysed. The age of the patients was ranged from 3 months to 60 years and there were 132 males [45.3%] patients and 145 female patients [54.6%] in this series. The most frequent type was oval type defect in 219 [86.9%]. The PAPVC were present in 7 patients of high defect group. Clinical analysis revealed 53 patients [19.9%] were asymptomatic. The QP/QS above than 3.61 were 45 patients and less than 1.5 were 24 patients. The pulmonary artery pressure was 10 to 100 mmHg. The majority of the defects were closed in primary suture and closed with a Dacron patch in 19 patients. The postoperative complications occurred in 35 patients [13.1%] and the most frequent complication was wound problem which was present in 10 patients. The hospital mortality rate was 1.6%.

Cardiac atrium is now well-known as an endocrine organ which secretes atrial natriuretic peptide (AMP), participating in the regulation of body fluid and blood pressure. ANP is released mainly from cardiac muscle cells in response to various physiological and pathological conditions to induce atrial stretch. Ca$\^$2+/ may be one of the most important factors affecting ANP secretion even though controversy still persists. The aim of the present study is to investigate the effect of lysophosphatidylcholines (LPCs) and moxonidine on atrial hemodynamics and ANP secretion in hypertrophied atria. LPC is an endogenous phospholipid released from cell membrane during ischemia, and moxonidine is a imidazoline 1 (Il) receptor agonoist.

A 18-year-old female underwent surgical correction of tricuspid atresia and complete transposition of great arteries combined with atrial 8 ventricular septal defect and pulmonary stenosis. After the transection of main pulmonary artery just above the pulmonic valve, proximal portion of main pulmonary artery was closed with running suture and distal portion of main pulmonary artery anastomosed with right atrial appendage without valve insertion. Atrial septal defect was closed with running suture. Postoperative course was uneventful and she discharged on 18th postoperative day. Her condition is in very good until present. Modified Fontan`s operation without valve placement [in the condition of low pulmonary vascular resistance and good left ventricular function] may has a good result.

Till June 1988, We experienced 3 cases of single atrium at Dept. of Thoracic k Cardiovascular Surgery of National Medical Center. Case 1 was 26 years old female, and had single atrium associated with partial cleft in mitral anterior leaflet and PAPVC. Atrial septation with Dacron patch and MVR [I-S, 31 mm] were done, followed by TAP, De Vega. Postoperative course was good, OPD follow-up for about 4 years with normal physical activity and ordinary working. Case 2 was 4 years old female with single atrium alone. Atrial septation with pericardial patch. Good postoperative course and OPD follow-up for about 2 years with appropriate physical growth. Case 3 was 22 years old female, single atrium with complete cleft in the anterior and posterior mitral leaflet, and septal tricuspid cleft were identified. Atrial septation with polystan bovine pericardial patch and repair of mitral anterior cleft. Postoperatively, residual regurgitation of mitral and tricuspid valve, but tolerable in some limitation of physical activity.

We at Keimyung University Dongsan Medical Center experienced simultaneous repair of pectus excavatum and secundum atrial septal defect We used resection deformed perichondrium, raising sternum at right angle to secure good operative field for open heart surgery. Mechanical ventilation was applied which could be weaned on postoperative 2 hours. The hospital course was uneventful without any other sequale. The patient was discharged on postoperative day 6.

A 75-year-old man was admitted to the hospital because of a pericardial effusion.After 3 L of blood-stained pericardial fluid was drained, clinical examination together with echocardiography and chest computed tomography showed a tumor in the right atrium. At operation a pedunculated vascular tumor was found with a broad base which was embedded in the atrial wall and extended into the pericardium.A wide resection was performed resulting in a large defect of the right atrial wall. The defect was reconstructed with a pericardial patch. The patient did well postoperatively, but bloody pleural effusion developed later, presumably because of pulmonary metastasis. The patient died 2 months after surgery as a result of respiratory failure.

The percutaneous transcatheter closure of secundum atrial septal defect has recently become an increasingly widespread alternative to surgical closure in many centers. Although immediate, short, and intermediate term results of percutaneous transcatheter septal closure are promising, the procedure is not free from inherent complications that could be lethal. We report a case of device embolization necessitating emergent surgical retrieval.

The number of patients suffering from atrial fibrillation is increasing and many cardiologists is trying to develop the ideal antiarrhythmic drugs for atrial fibrillation. An ideal antiarrhythmic agent would selectively prolong the action potential duration more in extraordinarily depolarized cardiac myocytes than in normal cells, and show tissue selectivity. Voltage-gated K$\^$+/ (Kv) channels represent a structurally and functionally diverse group of membrane proteins. These channels play an important role in determining the length of the cardiac action potential and are the targets for antiarrhythmic drugs. (omitted)

Atrial fibrillation (AF) is the most common arrhythmia associated with the risk of morbidity and mortality in clinical patients. AF is considered as an arrhythmia type that develops and progresses through close connection with cardiac structural arrhythmogenic substrates. Since the introduction of catheter ablation-mediated electrical isolation of arrhythmogenic substrates, cardiac imaging indicates improved treatment outcome and prognosis with appropriate candidate selection, ablation catheter guidance, and post-ablation follow-up. Currently, cardiac computed tomography (CCT) and cardiovascular magnetic resonance (CMR) imaging are essential in the case management of AF at both pre-and post-procedural stages of catheter ablation. In this review, we discuss the roles and technical considerations of CCT and CMR imaging in the management of patients with AF undergoing catheter ablation.

A 6-month-old male Ragdoll cat presented with exercise intolerance. On physical examination, there was a grade 2/6 systolic murmur at the right apex. Diagnostic tests, including SpO₂ measurement, blood tests, radiography, echocardiography, contrast echocardiography, and electrocardiography, were performed. Severe right atrial dilation, tricuspid valve leaflets and orifice displacement, right ventricular atrialization, septal leaflet adherence, anterior leaflet tethering, and right atrioventricular junction dilation were noted on echocardiography, alongside a right-to-left atrial septal defect. Cor triatriatum dexter and left ventricular aneurysm were observed. We diagnosed this case as having Ebstein anomaly with rare congenital heart deformities; which is rare in cats.
