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.

The present study suggests that lowering the diagnostic thresholds of HBP measurement from 135/85 mm Hg to 130/80 mm Hg may improve diagnostic accuracy for hypertension.

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 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.

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 Hemodialysis is one of the options designated in the Act as a life-sustaining treatment that can be withheld or withdrawn near death.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

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.

A transition from an open ICU model with trainee coverage to a closed ICU model with attending intensivist coverage can be expected to yield improvements in CSICU quality and reductions in postoperative complications.

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

Zone 2 hybrid TEVAR was associated with an acceptable early complication rate and provided acceptable mid-term aortic results for patients with AD, PAU, and TAI. However, patients with large AAs were at increased risk of aortic reintervention. In cases of large AA, clinicians should carefully consider whether zone 2 hybrid TEVAR or open surgical repair will be more effective for the patient.

Patients with unfavorable aortic anatomy showed relatively satisfactory short-term outcomes after EVAR. No difference in the surgical outcomes was observed in patients with a hostile neck. However, unfavorable iliac anatomy was found to inhibit the shrinkage of the aneurysmal sac.

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.

The octogenarians with acute type A aortic dissection had higher incidences of DeBakey type II dissection and intramural haematomas and lower incidences of severe aortic regurgitation and aortic root enlargement than the nonoctogenarians. Being an octogenarian was not associated with an increased risk of early major complications or mortality after surgery for acute type A aortic dissection.
