The thoracic aorta dilated with aging and was larger in subjects with a larger body size. Sex differences in the gross aortic diameter might be related to differences in body size. The growth of the thoracic aorta was faster in younger subjects with a smaller indexed diameter.

BACKGROUND: Differences between the recently suggested outcome-driven diagnostic threshold of home blood pressure (HBP) measurements and the currently recommended diagnostic threshold of HBP measurements may cause a disagreement between 24-hour ambulatory blood pressure (ABP) and HBP measurements in the diagnosis of hypertension. We evaluated the agreement of various HBP diagnostic thresholds (135/85, 130/85, and 130/80 mm Hg) to ABP measurements, as a reference method. METHODS: Patients who wer

Suitability rate of endovascular aneurysm repair (EVAR) and the anatomic features causing unsuitability have not been well determined in Asian patients who have abdominal aortic aneurysm (AAA). In a single Korean center, a total of 191 patients with abdominal aortic aneurysm (maximal diameter ≥ 4 cm) were identified. Aortoiliac morphologic characteristics in contrast-enhanced computed tomography images were retrospectively reviewed to determine suitability for EVAR with four FDA-approved stent-g

Volume of mural thrombus is an important risk factor for the elevation of inflammatory markers after EVAR.

The Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life came into effect on February 4th, 2018, in South Korea. Based on the Act, all Koreans over the age of 19 years can decide whether to refuse life-sustaining treatments at the end of life via advance directive or physician orders. Hemodialysis is one of the options designated in the Act as a life-sustaining treatment that can be withheld or withdrawn near death. However, hemodialysis

The Cox-maze IV procedure using RFBP2 and cryothermy is quite safe and freedom from atrial fibrillation at postoperative 6 month was 82.5%. Risk factors for failure or recurrence of atrial fibrillation after Cox-maze IV were old age and preoperative over moderate tricuspid regurgitation.

BACKGROUND: We aimed to investigate the associations of critical care provided in a cardiac surgical intensive care unit (CSICU) staffed by an attending intensivist with improvements in intensive care unit (ICU) quality and reductions in postoperative complications. METHODS: Patients who underwent elective isolated coronary artery bypass grafting (CABG) between January 2007 and December 2012 (the control group) were propensity-matched (1:1) to CABG patients between January 2013 and June 2018 (th

Coronary endarterectomy appears to be a safe option for patients with diffuse coronary artery disease, regardless of whether CPB or a specified selection of surgical techniques are used.

Completing an advance directive offers individuals the opportunity to make informed choices about end-of-life care. However, these decisions could be influenced in different ways depending on how the information is presented. We randomly presented 185 participants with four distinct types of advance directive: neutrally framed (as reference), negatively framed, religiously framed, and a combination. Participants were asked which interventions they would like to receive at the end of life. Betwee

In coronary artery bypass grafting (CABG) for patients on hemodialysis, there has been concern about “coronary steal”. This study aims to evaluate the influence of using an in situ internal thoracic artery (ITA) ipsilateral to a preexisting arteriovenous fistula (AVF) in dialysis-dependent patients undergoing CABG. Between 2004 and 2018, dialysis-dependent patients with AVFs who underwent CABG were enrolled. According to the locational relationship of AVFs and in situ ITA grafts, the patients we

BACKGROUND: Zone 2 thoracic endovascular aortic repair (TEVAR) is performed for the treatment of various thoracic aortic diseases involving the left subclavian artery. This study aimed to analyze the late clinical outcomes of zone 2 hybrid TEVAR according to the various indications. METHODS: A total of 48 patients who underwent zone 2 TEVAR at our institution between December, 2010 and July, 2020 were enrolled. The indications were aortic aneurysm (AA, n = 15), acute type B aortic dissection (AD

BACKGROUND: Endovascular aortic repair (EVAR) is widely performed to treat infrarenal abdominal aortic aneurysms (AAAs), and related techniques and devices continue to be developed. Although continuous attempts have been made to perform EVAR in patients with unfavorable aortic anatomy, the outcomes are still controversial. This study examined the short-term outcomes of EVAR for the treatment of infrarenal AAAs in patients with a 'hostile' neck and unfavorable iliac anatomy. METHODS: Thirty-eight

In the conventional way of thoraco-abdominal aortic replacement, the intercostal arteries are reimplanted directly to the main aortic graft or by the interposition of branch grafts. To overcome the disadvantages of these techniques, we adopted a different technique using a parallel side graft. The good patency rate of reimplanted intercostal arteries achieved by this technique and its potential technical advantages can contribute to the improvement of the surgical outcome.

OBJECTIVES: The clinical characteristics and early outcomes of surgical repair in octogenarians with acute type A aortic dissection were compared with those in nonoctogenarians. METHODS: All patients who underwent emergency surgical repair for acute type A aortic dissection in our institution between 2003 and 2022 were included in this study. The patients were divided into an octogenarian group and a nonoctogenarian group. The patients in the 2 groups were propensity score matched at a ratio of
