An 11-year-old, castrated male dog presented with a 3-month history of cough and depression. Auscultation revealed systolic murmur and thoracic radiographs showing enlargement of both the atrium and left ventricle. Echocardiography showed thickened mitral valve and moderate-to-severe left atrial enlargement. Additionally, M-mode echocardiography showed symmetric left ventricular wall thickening and systolic anterior motion of the mitral valve, while Doppler imaging revealed high velocity turbulent flow through the left ventricular outflow tract. Based on echocardiography, this case was diagnosed with hypertrophic obstructive cardiomyopathy. After 5 months, the dog was clinically static in radiography and echocardiography.

The malformation consisted of persistent left SVC terminating in left atrium, absence of coronary sinus, and atrial septal defect is considered as a developmental complex anomaly. We observed such a case associated with partial atrioventricular canal defect and common atrium. We operated it by intraatrial roofing [tunneling] along its course of the posterior wall of the left atrium using bovine pericardial patch, which was designed to contain some of thebesian veins, thereby, left superior vena caval and some coronary venous blood would be drained into venous side. Associated lesions were also corrected.

Pulmonary arteriovenous fistula is a congenital vascular malformation In the lung, various synonyms including Pulmonary cavernous vascular malformation, Pulmonary arteriovenous aneurysm, Cavernous hemangioma of the lung0 Pulmonary telangiectasia, Pulmonary hamartoma, etc. The pathogenesis of its symptoms is that unoxygenated, desaturated arterial blood enters into the pulmonary venous system directly. Recently we have experienced one case of the pulmonary arteriovenous fistula which was diagnosed as the pulmonary cystic lesion of the lung preoperatively in 20 years old, 61 kg, male patient. Operation was revealed well circumscribed cystic lesion filled with blood, subpleural and anterior mediobasal location, and bright red colored aspirates on two times needle aspirations. Microscopic finding shows ill circumscribed vascular lesion composed of varying sized blood vessels with irregular thickening of wall and final pathological diagnosis is Pulmonary Arteriovenous Fistula. Basal segmentectomy was done and the patient shows good postoperative course.

This is a report of a case of tuberculous esophageal perforation, which was surgically treated.. The patient was 32-year-old Korean female patient, who complained swallowing difficulty for` 4 weeks duration. Esophagogram was shown irregular filling defects in the upper one third of esophagus, about 4 cm in length. It was noticed that a small amount of contrast media was leaked out from the involved area of esophagus into the right mediastinum. It was highly suggested that abscess formation was due to perforation of esophageal cancer. Esophagoscopy revealed no definitive evidence of perforation of esophagus, but punch biopsy specimen of esophageal mucosa was shown acute and chronic inflammatory changes. Operation was performed under impression of esophageal cancer. In the right-sided upper mediastinum, a walnut-sized abscess cavity which was connected with esophagus through a fistulous tract was noted. A portion of cavity submitted for frozen section was shown tuberculous inflammation. The abscess cavity, fistula tract, and involved esophageal wall were removed. The perforated esophagus was closed layer by layer. The tuberculous changes were confirmed by histopathologic examination postoperatively. The postoperative course was uneventful.

Mediastinoscopy is a surgical endoscopic technique used mainly for examination and biopsy of lesions of the superior and posterior middle mediastinum. It is particularly concerned with diseases that primarily or secondary involve the paratracheal and parabronchial lymphatics. A total of 18 cases of mediastinoscopy are presented with a detailed analysis of indications and results. Of these mediastinoscopy was positive in i0 [56%] and negative in 8 [44%]. The 10 positive mediastinoscopies were diagnostic in 4 patients with malignant lymphoma, 5 patients with carcinoma of the lung, one patient with active pulmonary tuberculosis. Of 8 negative mediastinoscopies, one was inoperable due to recurrent laryngeal nerve involvement, 7 patients were subjected to radical resection. Complications of mediastinoscopy were developed in 2 cases, one was minimal degree of subcutaneous emphysema on anterior chest wall, and the other was widening of right mediastinal border due to hematoma. Two complications were completely absorbed after 7 days.

Pleural mesothelioma is usually divided into two forms of localized and diffuse type. Localized pleural fibrous mesothelioma is uncommon mesodermal neoplasm, which may occurs in both sexes and at the age of 50 years. This type of mesothelioma is usually asymptomatic and detected on routine chest X-ray and made fibrous tissue and shows of collagen fibers microscopically. Most localized fibrous mesothelioma arises from the visceral pleura and is well encapsulated and pedunculated mass. CT findings included well delineated, often lobulated, non-calcified soft tissue masses in close relation to a pleural space, associated pleural thickening, and absence of chest wall invasion and a peripheral or fissure location. Three cases of localized pleural fibrous mesothelioma diagnosed by resectional surgery were reported with the review of literature.

The unroofed coronary sinus syndrome is a spectrum of cardiac anomalies in which part or all the common wall between the coronary sinus and the left atrium is absent. This defect is part of a developmental complex which includes absence of the coronary sinus and termination of a persistent left superior vena cava in the left atrium. Recognition of this complex is important so that interruption or diversion of the left superior vena cava may be done to prevent subsequent central nervous system complications. Surgical correction uses an intraatrial baffle to divert flow from the left superior vena cava to right atrium and to close the atrial septal defect. This report describes a 7 years old female patient in whom the left superior vena cava was identified preoperatively and the complex [unroofed coronary sinus syndrome, common atrium, mitral valve cleft] recognized at the time of operation. Surgical correction, following repair of cleft mitral valve, utilized a Dacron patch baffle to route the left caval blood to the right atrium and included closure of the atrial septal defect

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.

Supraventricular tachyarrhythmias are readily characterized and understood, but the surgical procedures for their correction are complex and not easily mastered. Conversely, ventricular tachyarrhythmias are frequently difficult to characterize and localize electrophysiologically and their basic mechanisms are poorly understood. The role of the surgeon in the treatment of cardiac arrhythmia has changed dramatically during the past decade. This report is a case of 26 years old male with supraventricular tachyarrhythmia. The result of endocardial electrophysiologic study demonstrated accessory pathway connecting left atrium to left ventricle which located at left atrial free wall about 4 cm apart from the coronary sinus orifice. The accessory bundle interruption has been successfully accomplished utilizing the internal open heart technique. The operation consisted of dissection of the atrioventricular fat pad and division of all the superficial fibers going from the ventricle to the annulus. Following this, cryoablation made with cryoprobe at - 60` for 90 seconds. The accessory pathway was successfully ablated without specific problems.
