The study was to observe hemodynamic alterations of cardiac function to design a model of canine mitral valve insufficiency (MVI) based on chordae tendinae rupture (CTR). Ten healthy beagles with normal heart function were used in this study. To measure hemodynamics, the patient monitor was equipped for invasive blood pressure and a Swan-Ganz catheter. Hemodynamic alterations were checked promptly during CTR procedures. MVI model was made by transection of the chordae tendinae with small arthroscopy hook knife through $5^{th}$ intercostal open chest. Color Doppler at the level of the mitral valve showed high-velocity regurgitant flow immediately after CTR at intraoperative echocardiography. In hemodynamic measurements, pulmonary capillary wedge pressure (PCWP) was significantly increased, while mean arterial pressure (MAP), venous pressure (VP), pulmonary arterial pressure (PAP), cardiac output (CO) and cardiac index (CI) were significantly decreased after CTR. It was known that the left atrium was overloaded by regurgitant volume from the left ventricle. In conclusion, the MVI model induced by CTR technique in this study should be used as suitable one for the effective research of canine mitral valve disease. Further study should be needed to measure the chronic alternation of mitral valve in the model.

Traumatic rupture of the main bronchus is comparatively very rare. With the advent of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. Rupture of the bronchus is an unusual result of nonpenetrating trauma to the chest. Early recognition of bronchial rupture and emergency thoracotomy and management is essential for reducing of morbidity, mortality and late complications. We experienced 3 cases of bronchial rupture caused by nonpenetrating chest trauma with or without rib fracture. Patients were suffered from dyspnea and chest pain. After closed thoracostomy, corrective surgery was performed. Postoperative courses were uneventful and discharged without any complication.

Bilateral traumatic rupture of diaphragm is very rare. One case due to car accident is reported. Preoperative chest X-ray revealed the diaphragm rupture in the left side and the hemothorax in the right side. During the completion of left diaphragm repair through left thoracoabdominal incision, right diaphragm rupture was found incidentally. Left diaphragm was repaired using pledgets which were anchored at the thoracic wall. Right diaphragm was also repaired by interrupted Halsted sutures through seperated right thoracotomy. Postoperative course was uneventful.

The injuries to the bronchi have been reported with increasing frequencies. The most common cause of such injuries is compression or crushing chest trauma. Early diagnosis and emergent repair should be done for the good prognosis. We report 3 cases who had bronchial injuries after traffic accident. Our operative procedures were a primary bronchial repair for 17 months old boy, a pneumonectomy for delayed recognition and a bronchoplasty procedure 63 days after trauma. All these bronchial ruptures were successfully treated and discharged.

A case is presented of a steering wheel Injury to the chest which developed right atrial free wall rupture and cardiac tamponade without rib fractures or hemo-pneumothorax. A 30 year old man who sustained, blunt chest trauma by steering wheel injury to his chest developed right atrial rupture and cardiac tamponade. Pericardiocentesis was performed and cardiac tamponade was confirmed. After a median sternotomy, large right atrial free wall laceration [about 8cm] was noted. He was placed on cardiopulmonary bypass. The laceration wound of right atrium was closed with a 2 rows of continuous suture. Recovery was uneventful. The patient has returned to his previous level of activity.

The tracheobronchial rupture from blunt trauma is an uncommon injury with a variety of clinical presentations. Most of traumatic tracheobronchial tears occur within 2.5cm of the tracheal carina; lobar or segmental bronchi are rarely affected. Recently we experienced one case of traumatic rupture of right middle lobar bronchus in a patient who had fallen from a bicycle. Bronchoscopy showed linear disruption of the right middle lobe bronchus at its bifurcation site. Emergency right middle lobectomy was performed. The patient was recovered without any sequelae.

Over the past 3.5 years, 5 cases with ruptured sinus of Valsalva were operated upon at Asan Medical Center. Four patients were congenital and 1 traumatic. Coexistent lesions included 2 subarterial VSD, 3 AR requiring procedures [2 AVR, 1 valvoplasty], 2 subaortic membranes, 1 PDA,and 1 bicuspid AV. The communication is noncoronary sinus to RA in I and fight Coronary sinus to RV in the other 4 patients. The ~rstula was repaired through the aorta whenever possible and reinforced through the right sided chamber. There are no surgical mortality and, no recurrence of rupture yet.

Bichamber cardiac rupture is less frequent compared to unichamber cardiac rupture. We report a patient who was successfully treated after the diagnosis of penetrating stab wound of both ventricles. The key to improved outcome of management of cardiac trauma lies in the rapid transportation to a general hospital where cardiac surgery is available. Aggressive primary intervention and immediate operation are also major factors.

Although blunt traumatic cardiac rupture is an uncommon injury, it can be associated with a high mortality rate. Two cases of cardiac rupture in blunt trauma patients are described herein. In those cases, applications of mechanical support devices such as ECMO (extracorporeal membrane oxygenation) and early surgery for exploration under cardiopulmonary bypass may be helpful for treating blunt chest trauma patients.

We have experienced two cases of traumatic subclavian artery rupture at the department of thoracic and cardiovascular surgery, Youngdong Severance hospital, Yonsei University college of medicine. One was combined with brachial plexus injury and the other was combined with brachial plexus injury and subclavian vein rupture. They were treated with graft interposition after segmental resection of ruptured subclavian artery and neurorrhaphy for brachial plexus injury. Post operative courses were not eventful.
