Methods: Information on treatment modalities and diagnoses of BPH was obtained from the Health Insurance Review and Assessment Service-Aged Patient Sample.

A 10-year study of surgical results of descending aorta aneurysm repair following chronic aortic dissection.

Background: Patients presenting with descending aortic aneurysms developing after aortic dissection often undergo continued aortic expansion which may require operative interventions to address the risk of aortic rupture. In light of the current advances in various treatment options, including endovascular approaches, we analyzed our experience with open surgical repair (OSR) of aneurysms of the descending aorta following aortic dissection.

Methods: Patients who underwent open repair for aneurysmal changes of the descending aorta after chronic dissection were retrospectively studied.

Three-Dimensional Computed Tomographic Analysis of Normal and Aneurysmal Aortic Roots: Is There a Specific Geometric Pattern in the Aortic Root?

Current knowledge of the aortic root geometric anatomy and its surgical implications remain limited. We analyzed multiple predefined parameters of the aortic root to increase our understanding of the geometric changes that occur in normal and aneurysmal transformations. Between November 2003 and September 2015, the aortic roots of 107 healthy subjects (control group) and 105 annuloaortic ectasia (AAE) patients (AAE group) were analyzed using multiplanar reformatted computed tomographic images.

Guidelines for Transcatheter Aortic Valve Replacement in Korea: Past Obstacles and Future Perspectives.

Background: Analyses of the efficacy and safety of transcatheter aortic valve replacement (TAVR) in most countries have been based on outcomes obtained in accordance with national practice guidelines and monitoring protocols. The purpose of this study is to share our experience regarding the process for establishing guidelines and monitoring protocols for the use of TAVR in Korea, in the hopes that it may be helpful to others undergoing a similar process in their own country.

Methods: The Korean guidelines for TAVR were established on June 1, 2015 in through a tri-party agreement involving the Department of Health and Welfare, the Korean Society of Thoracic and Cardiovascular Surgery and the Korean Society of Cardiology.

A Systemic Review and Meta-Analysis of Sutureless Aortic Valve Replacement Versus Transcatheter Aortic Valve Implantation.

Background: Sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) are increasingly adopted methods to treat high-risk patients with severe aortic valve stenosis. We conducted a systematic review and meta-analysis to compare the clinical outcomes between these two recent methods to treat aortic valve disease.

Methods: We systematically searched multiple databases (January 2000 to October 2016) to identify original studies comparing clinical outcome between SU-AVR and TAVI.

Outcomes of ring versus suture annuloplasty for tricuspid valve repair in patients undergoing mitral valve surgery.

Objective: There is controversy regarding the comparative effectiveness of methods of tricuspid valve (TV) repair-prosthetic ring versus suture annuloplasty-in patients undergoing operation for primary mitral valve (MV) disease. In this study, we analyzed factors associated with patient survival and recurrent tricuspid regurgitation (TR) following TV repair and focused on results stratified by method of tricuspid valve repair.

Methods: We reviewed patients who underwent TV repair with suture (De Vega) or flexible ring annuloplasties at the time of MV surgery from 1995 to 2010.

Evidence-based surgical management of acquired tricuspid valve disease.

Tricuspid valve (TV) disease most often occurs secondary to left-sided heart disease, particularly mitral valve (MV) regurgitation or stenosis. Appropriate treatment, even when TV regurgitation is secondary to left-sided heart disease, can improve long-term outcome. Valvuloplasty is the most common procedure for TV disease, and has received an increasing amount of attention, as right-sided heart failure combined with TV regurgitation is associated with poor long-term outcome.

A simple method of substernal bar removal after the Nuss procedure.

The Nuss procedure for pectus excavatum is a well-known technique. Although there are numerous reports on the Nuss procedure, the reports on its removal are few. Removal has been done with many variations in the supine position, which involves bending the bar or bringing the bar beneath the operating table, which can prove to be troublesome and dangerous.

Double primary tumor, thymic mass and posterior mediastinal neurogenic tumor, in a patient with acute pancreatitis performed with single-staged robotic-assisted thoracoscopic surgery.

Finding 2 primary benign lesions at 2 extremes of the mediastinum is a rare event. A minimal invasive operation performed in a single-staged procedure can prove to be difficult, especially when the procedure is performed with a robot. We discuss the positioning and details of the procedure carried out in a 52-year-old woman with acute pancreatitis.

Primary peripheral pulmonary adenoid cystic carcinoma: report of a case diagnosed by fine needle aspiration cytology.

Adenoid cystic carcinoma (ACC) arising from anatomic sites other than the salivary gland is rare and those occurring in the lung are extremely rare. When arising from the lung, the tumor generally arises from extrapulmonary bronchi, originating from bronchial glands. Primary ACC of the lung located peripherally within lung parenchyma is an even rarer event.

Rib xanthoma resected by video-assisted thoracoscopic surgery using a bone punch.

Xanthomas of the rib are extremely rare benign neoplasms, most commonly reported in soft tissue, but rarely in bone. We report a case of a 4-cm xanthoma of the rib resected by video-assisted thoracoscopic surgery and pulled through a 2-cm port incision around the patient's areola. To the best of our knowledge, there are only 8 other such cases, and none of which were removed by thoracoscopic surgery.

Angiographic results of the radial artery graft patency according to the degree of native coronary stenosis.

Objective: Radial arteries are gaining widespread acceptance as complementary arterial conduits for surgical myocardial revascularization, but there are limited reports about its angiographic patency compared with that of the internal thoracic artery or saphenous vein according to the degree of native coronary stenosis. Therefore, we tried to evaluate the mid-term angiographic results of the radial artery graft patency focusing on the native coronary stenotic status in a prospective manner.

Methods: From March 2000 to September 2006, a total of 488 patients underwent coronary artery bypass grafting using radial artery graft at our institution.
