Successful factors for improving aortic remodeling with thoracic endovascular repair and bare stent extension.

Objective: Proximal ExTension to Induce COmplete ATtachment (PETTICOAT), which uses downstream bare metal stents for structural support, demonstrates potential, yet its adoption is limited by variable outcomes. This study elucidates the potential of PETTICOAT in aortic dissection, emphasizing the determinants that guide patient selection.

Methods: A retrospective analysis of 60 patients who underwent full PETTICOAT for aortic dissections was conducted.

Visualizing the invisible: aortopulmonary window diagnosis enhanced by 3D computer graphics.

An aortopulmonary window is a rare disorder that occurs in 0.1–0.2% of all congenital disorders.

Total arch replacement with extended branched stented anastomosis frozen elephant trunk repair for type A dissection improves operative outcome.

Objective: Emergency surgical repair is the standard treatment for acute aortic dissection type A. However, the surgical risk of total arch replacement remains high. The Viabahn Open Revascularization TEChnique has been used for supra-aortic reconstruction during total arch replacement.

A surgical sealant, AQUABRID decreased the volume of intraoperative blood transfusions and operative time for acute aortic dissection repair.

Background: The effect of the surgical sealant AQUABRID on outcomes after acute aortic dissection repair has not been evaluated. The objective of this study was to examine whether the use of AQUABRID affects the volume of intraoperative blood transfusion or operative time in patients undergoing emergency surgery to repair acute aortic dissection.

Methods: A multicenter retrospective cohort study from January 2007 to December 2021.

Comparison of patency of single and sequential radial artery grafting in coronary artery bypass.

Objectives: Sequential radial artery (RA) grafting has the potential to enhance arterial revascularization compared to single grafting. Sequential RA grafting was performed predominantly with a single side-to-side anastomosis. The study aimed to assess if sequential RA grafting improved long-term graft patency compared to single RA grafting.

Full PETTICOAT in acute type B aortic dissection with patent false lumen may offer positive remodeling for the distal aorta.

Objective: The provisional extension to induce complete attachment (PETTICOAT) technique is a unique thoracic endovascular aortic repair (TEVAR) for aortic dissection, which consists of proximal descending aortic endografting plus distal bare-metal stenting. This study aimed to investigate the efficacy of the PETTICOAT technique in patients with acute-sub-acute complicated type B aortic dissections. In particular, we compared the remodeling effect of full PETTICOAT covering down to the abdominal aorta with that of simple entry closure.

[Thrombectomy for right atrial thrombosis complicating a pyogenic liver abscess].

Vascular complications from a liver abscess are rare but life-threatening. Herein, we report the case of a man in his 40s with a pyogenic hepatic abscess complicated by an inferior vena caval thrombus extending to the right atrium. His presenting complaint was a high fever.

Giant Aneurysm of Coronary Artery Fistula Successfully Treated by Surgical Repair.

An asymptomatic 65-year-old woman was identified with an oversized round-shaped hypoechoic lesion (62 mm in diameter) between right and left atria by echocardiogram. A contrast-enhanced 320-slice multidetector computed tomography demonstrated a giant aneurysmatic fistula branched from the left main coronary trunk towards right atrium. The patient underwent an elective surgical repair.

Left atrial myxoma detected after an initial diagnosis of polymyalgia rheumatica.

We herein report the case of a 69-year-old woman with left atrial myxoma detected following treatment with glucocorticoids for an initial diagnosis of polymyalgia rheumatica (PMR). The glucocorticoids markedly improved the patient's symptoms, and the tumor was excised after rapidly tapering the glucocorticoid dose. The PMR-like symptoms did not recur and the inflammatory marker levels returned to normal after surgery.

Reconstruction of the free margin of the anterior mitral leaflet with autologous pericardium in active infected endocarditis.

In patients with active infective endocarditis mitral valve repair is better than mitral valve replacement, but it remains a challenge when there has been massive destruction of the rough zone of the anterior leaflet. We report a technical modification of mitral valve repair for advanced active infective endocarditis in which a widely infected rough zone and the chordae were successfully replaced with autologous pericardium and multiple artificial chordae. The procedure described here is capable of improving the prospects of mitral valve repair in advanced infective endocarditis.

Apicoaortic valved conduit with an apical connector for aortic stenosis with a calcified aorta.

We report a case of apicoaortic bypass using an apical connector for severe aortic stenosis. A 74-year-old woman suffered from severe aortic stenosis, with a small aortic annulus and a severely calcified aorta. A valved conduit with an apical connector was placed between the left ventricular apex and the descending thoracic aorta because the risk of aortic valve replacement was high.

Cerebral perfusion using the tissue oxygenation index in mitral valve repair in a patient with porcelain aorta and aortic regurgitation.

We report successful mitral valve repair in a patient with porcelain aorta, complicated by aortic regurgitation, severe cerebrovascular disease, and multiple cerebral infarctions. The patient was a 77-year-old male who had congestive heart failure as a result of severe mitral regurgitation. Mitral valve repair was performed without aortic cross-clamping, using moderate hypothermic cardiopulmonary bypass.

Administration of granulocyte colony-stimulating factor after myocardial infarction enhances the recruitment of hematopoietic stem cell-derived myofibroblasts and contributes to cardiac repair.

The administration of granulocyte colony-stimulating factor (G-CSF) after myocardial infarction (MI) improves cardiac function and survival rates in mice. It was also reported recently that bone marrow (BM)-derived c-kit(+) cells or macrophages in the infarcted heart are associated with improvement of cardiac remodeling and function. These observations prompted us to examine whether BM-derived hematopoietic cells mobilized by G-CSF administration after MI play a beneficial role in the infarct region.

Changes in left ventricular volume and predictors of cardiac events after endoventricular circular patch plasty.

Objective: The aim of this study was to identify predictors of cardiac events after endoventricular circular patch plasty (Dor operation) by analyzing our experience with Dor operation.

Methods: Thirty patients with left ventricular aneurysm and/or ischemic cardiomyopathy who underwent Dor operation were included in this study. Hemodynamic and clinical results were analyzed, and the predictors of cardiac events were examined.

Resection of giant right atrial lymphoma using vacuum-assisted cardiopulmonary bypass without snaring the inferior vena cava.

A 53-year-old man sustained hemodynamic collapse due to a huge right atrial tumor and was transferred to our hospital and underwent a life-saving emergency operation. The tumor arose from the inferolateral wall of the right atrium, occupying almost the whole right atrial cavity and obstructing not only the inflow of the right ventricle but also the orifice of the inferior vena cava. Venous cannulation via the right atrial wall and placing a snare around the inferior vena cava were impossible.

Mortality and morbidity after total arch replacement using a branched arch graft with selective antegrade cerebral perfusion.

Background: The early outcome after aortic arch surgery has improved. However, some operative survivors have died as a result of postoperative problems soon after discharge. This study determines the factors affecting mortality within 1 year of total arch replacement.

Apico-pulmonary artery conduit repair of congenitally corrected transposition of the great arteries with ventricular septal defect and pulmonary outflow tract obstruction: a 10-year follow-up.

Background: In conventional repair of the congenitally corrected transpositions of the great arteries associated with ventricular septal defect and pulmonary outflow tract obstruction, the placement of the left ventricle-pulmonary artery conduit is at risk owing to probable compression by the sternum, heart block, or injury to the mitral anterior papillary muscle. Apical placement of the left ventriculotomy for the inflow conduit rather than in the midportion or base placement may avoid these complications, although this results in a long and winding extracardiac conduit that may be short-lived because of the proliferation of pseudointima.

Methods: Between 1985 and 1990, a nonvalved Dacron woven-fabric graft conduit was placed between the left ventricular apex and pulmonary artery in 5 patients (mean age, 6.

Liberal use of tricuspid valve detachment for transatrial ventricular septal defect closure.

Background: Although temporary tricuspid valve detachment is useful for improved visualization of ventricular septal defect through right atriotomy, liberal use of this adjunct is not widely supported, mainly because of concerns about iatrogenic complications such as heart blocks and tricuspid valve dysfunction. The objective of this study was to determine whether liberal use of this adjunct can improve operative outcome.

Methods: Between January 1997 and March 2002, trans-atrial closure of isolated ventricular septal defect (conoventricular or canal type) was performed in 87 consecutive patients.
