Bypass Grafting to Circumflex: Left Internal Thoracic Artery versus Saphenous Vein.

Background: This study aimed to compare the short- and long-term outcomes of saphenous vein grafts (SVGs) and in situ left internal thoracic artery (LITA) grafts to the left circumflex artery (LCX) territory.

Methods: This study included 678 patients who underwent LITA-left anterior descending (LAD) + SVG-LCX grafts and 286 patients who underwent right internal thoracic artery (RITA)-LAD + in situ LITA-LCX grafts from January 2002 to December 2020. Short-term and long-term clinical outcomes were compared using inverse probability of treatment weighting adjustment to reduce selection bias.

Very-long-term outcomes of mechanical valves in mitral position focusing on valve-related complications.

Objectives: This study aimed to examine very-long-term outcomes of a mechanical valve at the mitral position.

Methods: This study included all patients who underwent mitral valve replacement (MVR) using a mechanical valve including urgent operation at the Department of Cardiovascular Surgery, Hyogo Brain and Heart Center, Himeji, from January 1987 to December 2015.

Results: Five hundred and eighty-three patients (277 men [47.

Distal Stent Graft-Induced New Entry after Total Arch Replacement with Frozen Elephant Trunk for Aortic Dissection.

Distal stent graft-induced new entry (dSINE), defined as a new tear caused by a stent graft, has been increasingly observed following total arch replacement using frozen elephant trunk (FET) for aortic dissection. We aimed to investigate the incidence and treatment of dSINE after the use of FET. This retrospective study evaluated 70 patients who underwent total arch replacement using FET for aortic dissection between August 2014 and March 2020.

Modes of the bioprosthetic valve failure of the porcine and pericardial valves in the mitral position.

Objectives: This study was conducted to examine the incidence and modes of the bioprosthetic valve failure of the porcine valve in the mitral position and compare them with those of the pericardial valve.

Methods: This study included 240 patients (116 men [48.3%]; mean age, 74.

Dynamic changes in insulin requirements with post-operative time using bedside artificial pancreas to maintain normoglycemia without hypoglycemia after cardiac surgery.

It is difficult to manage postoperative blood glucose levels without hyperglycemia and hypoglycemia in cardiac surgery patients even if continuous intravenous insulin infusion is used. Therefore, the insulin requirements for maintaining normoglycemia may be difficult to evaluate and need to be elucidated. In this single-center retrospective study, 30 adult patients (age 71.
