[Thoracic Endovascular Aortic Repair for Mycotic Thoracic Aortic Aneurysm After BCG Intravesical Therapy].

Bacille Calmette-Guérin( BCG) intravesical therapy is an effective and safe treatment for bladder cancer; however, mycotic aneurysms have been reported as a rare complication. Case 1:A 64-year-old man with a history of BCG intravesical therapy underwent emergent thoracic endovascular aortic repair (TEVAR) for a ruptured thoracic aortic aneurysm (TAA). He was diagnosed with BCG infection by hemosputum specimen culture five months later;then, antituberculous therapy was initiated.

Mitral valve plasty in a patient with multiple cerebral cavernous malformations: A case report.

Cerebral cavernous malformations (CCMs) are blood vessel malformations, often untreated if asymptomatic. However, upon cardiac surgery with cardiopulmonary bypass, cerebral edema/hemorrhage may occur. We successful performed mitral valve plasty for a case of severe mitral regurgitation with multiple CCMs.

Takayasu Arteritis Complicated by Ischemic Colitis: A Case Report.

Takayasu arteritis is an inflammatory disease of the aorta and its major branches, which results in stenosis and aneurysm formation. Lesions of the abdominal aorta and renal arteries are common. Nevertheless, lesions of the celiac and superior mesenteric arteries are less common.

Anastomotic stenosis of a reconstructed dissecting superior mesenteric artery aneurysm undetectable by intraoperative indocyanine green angiography: A case report.

Intraoperative evaluation of blood flow using ICG angiography revealed no significant abnormality. However, the anastomotic stenosis was revealed by postoperative CT angiography; more precise intraoperative evaluation methods need to be developed.

Diagnosis of Carney complex following multiple recurrent cardiac myxomas.

Carney complex is a rare syndrome caused by a genetic mutation leading to multiple endocrine abnormalities and a variety of tumors. Here, we report a case of Carney complex diagnosed due to recurrent multiple myxomas in the right atrium of a patient 16 years after the resection of the primary left atrial myxoma. Surgical excision was performed for the multiple recurrent right atrial tumors under cardiopulmonary bypass.

Application of the Konno procedure for infective endocarditis in native bicuspid aortic valve with annular abscess extending into the interventricular septum.

Annular abscess is a serious complication of infective endocarditis, which often requires complex surgery and has a very high post-operative mortality rate. The Konno procedure involves valve annuloplasty for a narrow aortic annulus or left ventricular outflow tract stenosis in children; it is also performed for various cardiac conditions in adults. Here, we report a case of the Konno procedure performed in a patient with aortic valve infective endocarditis, with an annular abscess extending into the interventricular septum (IVS).

Peak Lag Between Plasma Vasopressin and Urine Aquaporin-2 Following Cardiac Surgery.

Tolvaptan, a vasopressin type-2 receptor antagonist, is utilized to ameliorate fluid retention following cardiac surgery. However, the optimal timing of tolvaptan administration considering novel biomarkers remains unknown. We prospectively included patients who underwent cardiac surgery between 2016 and 2020.

Iatrogenic diversion of the inferior vena cava into the left atrium diagnosed 43 years after surgical atrial septal defect closure.

The diversion of the inferior vena cava into the left atrium after surgical atrial septal defect closure is a fatal complication. Cases of atrial septal defect with no inferior rim should be treated with this complication in mind.

Impact of a long-term high-glucose environment on pro-inflammatory responses in macrophages stimulated with lipopolysaccharide.

Cumulative evidence has established that macrophages orchestrate inflammatory responses that crucially contribute to the pathogenesis of insulin-resistant obesity and type 2 diabetes. In the present study, we examined the impact of hyperglycemia on macrophage pro-inflammatory responses under an inflammatory stimulus. To conduct this study, RAW264.

Surgical repair of a right coronary aneurysm with a coronary artery fistula to the right atrium.

A coronary artery fistula is a rare condition caused by abnormal coronary artery embryological development. Although most cases are asymptomatic, in some, the large shunt volume and the myocardial ischemia due to the steal phenomenon require surgical treatment. We present the case of a 40-year-old woman who presented with angina on exertion.

Congenital vascular ring.

A vascular ring is a rare congenital cardiovascular anomaly, which encircles and compresses the trachea or esophagus, or both. In this review we discuss the pathophysiology, theoretical embryopathogenesis, diagnostic modalities, and surgical treatment of the different types of vascular ring. Knowledge of the normal embryonic development of the aortic arch and related structures is important for understanding and classifying the various forms of vascular ring.

Different involvement of the MAPK family in inflammatory regulation in human pulmonary microvascular endothelial cells stimulated with LPS and IFN-γ.

Pulmonary endothelial injury is central in the pathogenesis of acute lung injury (ALI). The MAPK signaling cascades are generally thought to be involved in the molecular mechanism underlying the ALI development, but their roles in pulmonary endothelial injury is poorly understood. We thus examined the involvement of the MAPK family member in inflammatory responses of human pulmonary microvascular endothelial cells (HPMVECs) stimulated with LPS and IFN-γ.

Cardioprotective and functional effects of levosimendan and milrinone in mice with cecal ligation and puncture-induced sepsis.

Levosimendan and milrinone may be used in place of dobutamine to increase cardiac output in septic patients with a low cardiac output due to impaired cardiac function. The effects of the two inotropic agents on cardiac inflammation and left ventricular (LV) performance were examined in mice with cecal ligation and puncture (CLP)-induced sepsis. CLP mice displayed significant cardiac inflammation, as indicated by highly increased pro-inflammatory cytokines and neutrophil infiltration in myocardial tissues.

[Septic cardiomyopathy: pathophysiology and potential new therapeutic approaches].

Sepsis is the leading cause of death in critically ill patients, and its incidence continues to rise. Sepsis was defined as a systemic inflammatory response syndrome with an identifiable focus of infection, but therapeutic strategies aimed at eliminating the inflammatory response have only modest clinical benefit. The development of a failure of one or more organs poses a major threat to the survival of patients with sepsis, and mortality in sepsis is most often attributed to multiple organ dysfunction.

Diminished responsiveness to dobutamine as an inotrope in mice with cecal ligation and puncture-induced sepsis: attribution to phosphodiesterase 4 upregulation.

Dobutamine has been used in septic shock for many years as an only inotrope, but its benefit has been questioned. We weighed the effects of dobutamine and milrinone as inotropes in mice with cecal ligation and puncture (CLP)-induced polymicrobial sepsis. CLP-induced septic mice exhibited significant cardiac inflammation, as indicated by greatly increased mRNAs of proinflammatory cytokines and robust infiltration of inflammatory cells in the ventricular myocardium.

Surgery for total anomalous pulmonary venous connection: primary sutureless repair vs. conventional repair.

Despite recent advances in surgical technique and perioperative care, the surgical correction of total anomalous pulmonary venous connection (TAPVC) remains a challenge. The major complication and the main cause of reoperation in TAPVC surgery are the occurrence of pulmonary venous obstruction (PVO). In the 1990s, sutureless repair was introduced as a technique to relieve PVO after TAPVC repair.

[Current status and prospect of off-pump pulmonary vein isolation for atrial fibrillation].

We reviewed our clinical experience in off-pump pulmonary vein isolation (PVI) using bipolar radiofrequency (RF) device for atrial fibrillation (Af). From August 2004 to July 2007, the combined off-pump PVI and coronary artery bypass grafting (CABG) was performed in 13 of the 22 planned patients. There was no operative mortality or major complication.
