[Distal Stent Graft-induced New Entry after Total Arch Replacement for the Aortic Dissection:Report of a Case].

A 73-year-old man after total arch replacement with open stent graft (OSG) technique for Stanford type B aortic dissection was found to have expanding descending aortic aneurysm. Contrast-enhanced computed tomography (CT) showed distal stent graft-induced new entry (distal SINE). We successfully performed additional thoracic endovascular aortic repair (TEVAR).

Left Ventricular Pseudoaneurysm With a Bead-Like Appearance After Myocardial Infarction: The Utility of Cardiac Computed Tomography.

A left ventricular pseudoaneurysm is a rare but life-threatening complication after myocardial infarction. Because untreated pseudoaneurysms have a 30%-45% risk of rupture, surgery is the preferred therapeutic option. However, its diagnosis is sometimes challenging, as a pseudoaneurysm presents with non-specific symptoms that can mimic myocardial infarction or heart failure.

Incidental retroaortic innominate vein in a patient with acute aortic dissection.

Background: Retroaortic innominate vein is a rare anomaly. It has been reported in patients with congenital anomalies such as Tetralogy of Fallot or right aortic arch. However, isolated retroaortic innominate vein is quite rare.

Critical left coronary main trunk stenosis, chronic occluded right coronary artery, left subclavian artery occlusion, severe aortic regurgitation and porcelain aorta in a patient with aortitis.

Background: Coronary involvement is rare but can be critical in patients with aortitis. Although cardiac ischemia can be resolved by coronary artery bypass grafting (CABG), patients complicated with cardiac ischemia, calcified aorta, and valve insufficiency pose difficult problems for surgeons.

Case Presentation: A 71-year-old woman was referred to our institution because of unstable angina.

Aorto-carotid bypass for type A acute aortic dissection complicated with carotid artery occlusion: no touch until circulatory arrest.

The surgical management for type A acute aortic dissection complicated with carotid artery occlusion remains controversial. Between December 2012 and June 2017, 127 patients who presented with type A acute aortic dissection were operated on in our hospital. Of this group, nine (7.

Ventriculitis after emergent arch aneurysm surgery.

A 72-year-old man was referred to our institution because of an arch aneurysm and acute aortic dissection (thrombosed Stanford type A). Anti-impulse therapy was initiated. He developed a high fever after admission.

Was the internal thoracic arterial graft selection for coronary artery bypass grafting appropriate in a patient with neurofibromatosis-1?

Neurofibromatosis type 1, also called von Recklinghausen's disease, is a hereditary congenital disorder that affects tissues of neuroectodermal or mesodermal origin. This disease has various manifestations, including pigmented skin lesions, cutaneous neurofibromas, skeletal abnormalities, and tumors of the central/peripheral nervous and gastrointestinal systems, and vascular abnormalities. Because of vasculopathy, part of the vessel wall may be replaced by neurofibromatosis tissue.

[Simultaneous Transapical Transcatheter Aortic Valve Implantation and Coronary Artery Bypass Grafting;Report of a Case].

Coronary artery disease(CAD) is often found concurrently in patients presenting with severe aortic stenosis(AS). Surgical aortic valve replacement(SAVR) and coronary artery bypass grafting(CABG) were usually selected with such patients. Recently, transcatheter aortic valve implantation (TAVI) is considered as a less invasive and more feasible treatment option in high-risk AS patients.

[Redo Coronary Artery Bypass Grafting Through Left Thoracotomy in Patient with Patent Left Internal Thoracic Artery Graft;Report of a Case].

A 61-year-old man was admitted because of unstable angina. The patient had a history of CABG [LITA-left anterior descending artery(LAD), aorta-saphenous vein graft(SVG)-posterolateral branch (PL)-diagonal branch (D1)]4 years ago. Coronary angiography revealed an occlusion of old SVG at proximal anastomosis site and a stenosis of native high lateral artery (HL).

[Native Aortic Valve Endocarditis Caused by Nocardia asteroides;Report of a Case].

Infection by Nocardia sp. is rare and usually affects immuno-depressed patients, such as those receiving chemotherapy and long-term steroid therapy. Cardiac involvement is uncommon and usually occurs as endocarditis.

Effect of landiolol hydrochloride after off-pump coronary artery bypass.

Objectives: many studies have shown that oral beta blockers reduce the incidence of atrial fibrillation after coronary artery bypass. The goal of this study was to determine whether landiolol, an intravenous beta blocker, reduces the incidence of atrial fibrillation after off-pump coronary artery bypass.

Methods: 39 consecutive patients were given landiolol after coronary artery bypass, and 20 who were not given landiolol served as a control group.

A Case of Acute Aortic Dissection with Intimal Tear Found at 1 cm Above Previous Aortotomy.

Although it is rare, acute aortic dissection after cardiac surgery predisposes the patients to critical condition such as rupture, tamponade and death. Prompt diagnosis and treatment is mandatory for this fatal complication. We present our case in which acute aortic dissection occurred 7 years after aortic valve replacement.

[Total arch replacement for spontaneous rupture of the thoracic aorta;report of a case].

A 75-year-old man without history of trauma and aortic aneurysm presented with chest discomfort. A computed tomography (CT) revealed massive mediastinal hematoma without intimal flap in the aorta. Under hypothermic circulatory arrest, total arch replacement was performed.

Biatrial myxomas with Carney complex.

A 30-year-old man presented with chest pain and was diagnosed with biatrial myxomas and pulmonary embolism. He underwent resection of the biatrial myxomas and tumor embolectomy from the pulmonary artery. The histological diagnosis was multiple cardiac myxomas.

[Intercostal lung hernia diagnosed by computed tomography images under the semilateral position].

A 62-year-old man developed a swelling of the left anterior chest after surgery for a thoracic aortic aneurysm. Chest computed tomography (CT) images in the left semilateral position, which were obtained when his intrathoracic pressure was elevated through the Valsalva maneuver, showed a herniated lung with a fragile site of the surgical wound in the chest wall as a hernial orfice, as well as a hernial sac in the posterior of the greater pectoral muscle. A diagnosis of traumatic hernia occurring after thoracotomy was made, for which radical surgery involving direct closure was performed.

[Preferable surgical approaches to the aortic root-arch in patients with functioning tracheostomy].

Preferable surgical approaches to aortic diseases occurring between the aortic root and the arch in patients with functioning tracheotomy or permanent tracheostomy are described for securing adequate exposure and avoiding postoperative mediastinitis. Case 1: A 41-year-old man with Marfan syndrome presented with chronic type A thrombosed aortic dissection and severe aortic valve regurgitation. He had had a functional tracheostomy for managing respiratory function due to traumatic spinal cord damage.

Chronic expanding intrapericardial hematoma after pericardial paracentesis.

Chronic expanding intrapericardial hematoma (CEIH) is rare. A thorough search of literature revealed a few cases after open heart surgery, chest trauma, or epicardial injury. We report the case of a 72-year-old man presenting with a large CEIH and constrictive pericarditis, who had no past history of the above conditions but had undergone pericardiocentesis four years earlier.

Antithrombogenicity of the Gyro permanently implantable pump with the RPM dynamic suspension system for the impeller.

In 1995, a group at Baylor College of Medicine started to develop the NEDO biventricular assist device (BVAD) using two Gyro permanently implantable (PI) centrifugal pumps. This pump consists of a sealless pump housing and an impeller supported with a double pivot bearing. In May 2001, an RPM dynamic suspension system (RPM-DS) for the impeller was developed to improve durability and antithrombogenicity without a complex magnetic suspension system.

Development of silicone rubber hollow fiber membrane oxygenator for ECMO.

Silicone rubber hollow fiber membrane produces an ideal gas exchange for long-term ECMO due to nonporous characteristics. The extracapillary type silicone rubber ECMO oxygenator having an ultrathin hollow fiber membrane was developed for pediatric application. The test modules were compared to conventional silicone coil-type ECMO modules.

In vivo evaluation of the NEDO biventricular assist device with an RPM dynamic impeller suspension system.

Since 1995, the Baylor College of Medicine group has been developing the NEDO Gyro permanent implantable (PI) pump. The Gyro PI pump has achieved outstanding results up to 284 days with no thrombus formation during the left ventricular assist device (LVAD) animal experiments. However, in biventricular assist device (BVAD) animal experiments, thrombus formation did occur.

Physiological adaptation to a nonpulsatile biventricular assist system.

Physiological adaptation of the recipient to a nonpulsatile biventricular assist system (NPBVAS) is not well understood. The aim of this study is to evaluate the physiological adaptation of experimental animals after NPBVAS implantation. Since May 2001, four long-term NPBVAS implant experiments in calves were performed.

Hemolytic characteristics of oxygenators during clinical extracorporeal membrane oxygenation.

A connection was previously reported between the hemolytic characteristics associated with oxygenators and the pressure drop measurements in the blood chamber under experimental conditions simulating their use in cardiopulmonary bypass. We examined this association during extracorporeal membrane oxygenation (ECMO) conditions. Three oxygenators for ECMO or pediatric cardiopulmonary bypass (Menox EL4000, Dideco Module 4000, and Mera HPO-15H) were evaluated.

Titania gel reduces thrombin generation.

Titanium alloy (Ti) commonly is used for long-term blood pumps as a conventional blood contacting material. Thrombus formation in the pump, however, is still a critical problem. Once thrombin is generated on the Ti surface, it activates platelets and the coagulation cascade, leading to thrombus formation.
