Endoscopic sympathicotomy is the choice of the treatment for hyperhidrosis. There are some recognized risks such as Honer's syndrome and Hemopneumothorax; however, Chylothorax has very rarely been reported after thoracic sympathicotomy. We recently encountered a case of chylothorax. Early diagnosis and prompt treatment is noteworthy.

A 79-year-old man was admitted to Samsung Changwon Hospital due to chest pain and dyspnea. The ejection fraction was 31% and mean pressure gradient between the left ventricle and aorta was 69.4 mmHg on echocardiography. Chest computed tomography showed severe calcification of the ascending aorta. Aortic valve replacement was successfully performed using a thoracic endovascular aortic repair balloon catheter without classic aortic cross clamping. The patient was discharged on the eleventh postoperative day.

It is expected that the stent graft will become an alternative method for treating aortic diseases or reducing the extent of surgery; therefore, thoracic endovascular aortic repair has widened its indications. However, it can have rare but serious complications such as paraplegia and retrograde type A aortic dissection. Here, we report a surgical repair of retrograde type A aortic dissection that was performed after thoracic endovascular aortic repair.

A 70-year-old man with dilated cardiomyopathy underwent left ventricular assist device (LVAD) implantation, using a HeartWare ventricular assist device, as a bridge to candidacy. After 26 months, computed tomography (CT) angiography indicated stenosis in the LVAD outflow graft; however, the patient was asymptomatic, prompting a decision to manage his condition with close monitoring. Ten months later, the patient presented with dizziness and low-flow alerts. Subsequent CT angiography revealed a critical obstruction involving the entire LVAD outflow graft. The patient underwent emergency surgery, during which an organized seroma causing the graft obstruction was found between a wrapped expanded polytetrafluoroethylene (ePTFE) graft and a Dacron outflow graft. The covering of the outflow graft was removed, along with the organized seroma. Following removal of the ePTFE wrap and decompression of the outflow graft, normal LVAD flow was reestablished. The practice of wrapping the outflow graft with synthetic material, commonly done to facilitate later redo sternotomy, may pose a risk for outflow graft obstruction.

From 1959 through Jun. 1988, 2094 cases of various Cardiovascular diseases were operated, which were consisted of 1215 open heart surgery under extra-corporeal circulation or hypothermia and 879 conventional Cardiovascular Surgery at Department of Thoracic & Cardiovascular Surgery in National Medical Center. There were 1111 congenital heart anomalies and 983 acquired cardiovascular diseases. Among 1111 congenital cases, acyanotic cases were 748 and cyanotic cases were 363. In acquired heart cases, valvular heart diseases [702 cases] were the most frequent and a small No. of cardiac tumor and coronary artery diseases were included. Overall operative mortality was 9.3%, consisting of 4.6% for acyanotic anomaly, 20.6% for cyanotic anomaly and 8.7% for acquired heart diseases. In open heart surgery, overall mortality was 11.6% and 6% in conventional cardiovascular surgery.

Background: This study aimed to develop a new risk prediction model for operative mortality in a Korean cohort undergoing heart valve surgery using the Korea Heart Valve Surgery Registry (KHVSR) database. Methods: We analyzed data from 4,742 patients registered in the KHVSR who underwent heart valve surgery at 9 institutions between 2017 and 2018. A risk prediction model was developed for operative mortality, defined as death within 30 days after surgery or during the same hospitalization. A statistical model was generated with a scoring system by multiple logistic regression analyses. The performance of the model was evaluated by its discrimination and calibration abilities. Results: Operative mortality occurred in 142 patients. The final regression models identified 13 risk variables. The risk prediction model showed good discrimination, with a c-statistic of 0.805 and calibration with Hosmer-Lemeshow goodness-of-fit p-value of 0.630. The risk scores ranged from -1 to 15, and were associated with an increase in predicted mortality. The predicted mortality across the risk scores ranged from 0.3% to 80.6%. Conclusion: This risk prediction model using a scoring system specific to heart valve surgery was developed from the KHVSR database. The risk prediction model showed that operative mortality could be predicted well in a Korean cohort.

Thoracic endovascular aortic repair has become a widespread alternative treatment option for thoracic aortic aneurysm. The debranching of arch vessels may be required to provide an acceptable landing zone for an endovascular stent graft. We report a case where the bypass graft used in the thoracic endovascular aortic repair procedure compressed the left internal jugular vein, causing acute thrombotic occlusion.

Thoracic outlet syndrome (TOS) due to thoracic trauma is a rare disorder. Surgical treatment of TOS is especially rare. We report here a case of traumatic TOS caused by right 1st rib and clavicular fracture after a traffic accident. The patient underwent first rib resection and open reduction with fixation of the clavicle through axillary and supraclavicular incisions.

In an extremely enlarged right heart, the repeated midline sternotomy was considered to involve the risk of massive hemorrhage. A right thoracotomy provides a convenient and safe way to approach the tricuspid valve in patient who have had previous heart surgery through a midline sternotomy.
