Iatrogenic acute type A aortic dissection during catheter ablation for idiopathic ventricular premature contraction.

Acute aortic dissection type A during cardiac catheterization has been reported as a rare but fatal complication. We present a case of acute aortic dissection type A occurring during catheter manipulation in the ascending aorta during mapping of ventricular premature contraction via the retrograde approach. In the present case, transthoracic echocardiography showed no pericardial effusion and no flap of the aorta, but intracardiac echo clearly showed the flap.

Giant coronary artery aneurysm occluded completely by a thrombus.

A coronary artery aneurysm is an uncommon vascular disorder, and it can be a life-threatening disease when associated with rupture or an embolism. A 52-year-old man was found to have a 50-mm coronary artery aneurysm at the right coronary artery, and the aneurysm was completely occluded by a thrombus. He had no symptoms after arriving at our hospital, and his hemodynamics was stable.

Surgical techniques for infectious endocarditis of the mitral valve with hypertrophic cardiomyopathy in Costello syndrome.

Costello syndrome is a rare congenital disease caused by activating germline mutations, and it is often associated with cardiac abnormalities. A 17-year-old male with a history of Costello syndrome presented with persistent fever. Vegetation attached to anterior mitral leaflet was detected, and antibiotic therapy was administered as treatment for infectious endocarditis.

Plaster technique for filling up a future entry at the suture hole in type A aortic dissection.

Unlabelled: Although the surgical technique for acute type A aortic dissection dramatically improved in recent years, the postoperative mortality and morbidity rates remain high. After the emergency surgery for acute type A aortic dissection, a small tear in the aorta may result in dilation of the false lumen in the future. Some tears originate from the suture line on the anastomosis.

Beating pulmonary vein sign during catheter ablation.

The beating of a pulmonary vein during cardiac catheterization is a rare phenomenon caused by the heart beating through the pericardial effusion when a cardiac tamponade occurs. This "beating pulmonary vein" sign is useful for early detection of a tamponade before circulatory collapse occurs.

Abdominal aortic aneurysm mimicking the cause of gastric obstruction.

A case of abdominal aortic aneurysm appeared to be compression of the antrum of the stomach and was suspected of causing a gastric obstruction. However, an upper gastrointestinal endoscopy to rule out an obstruction by a tumor revealed a gastric tumor, thus avoiding unnecessary intervention, such as open surgery.

Late-phase left ventricular pseudoaneurysm after three-time mitral valve surgery.

Rupture of the left ventricular posterior wall is a fatal complication during mitral valve replacement (MVR), and rupture mainly occurs intraoperatively and up to several days after MVR, but it rarely occurs in the late phase, such as several years postoperatively. Late rupture occasionally presents as left ventricular pseudoaneurysms (LVPAs). A 40-year-old man who had a three-time history of mitral valve surgery for infectious endocarditis was incidentally found to have a left ventricular aneurysm with no symptoms.

Late detection of communication between juxtaposed atrial appendages.

A 40-year-old woman underwent an atrial septal defect closure 4 years before presentation. During the operation, juxtaposition of the atrial appendages was found simultaneously but no obvious communication was found between the appendages. She recently experienced desaturation on exercise, and the residual communication was found between the juxtaposed atrial appendages.

Pericardioperitoneal and pericardiopleural windows: A drainage technique for the treatment of recurrent cardiac tamponade. A case report.

Introduction: Given that pericardial effusion may sometimes lead to cardiac tamponade and chronic heart failure, its management seems absolutely essential. In case of a poor response to medical therapy, surgical drainage of the effusion is required. Although some drainage procedures for pericardial effusion (e.

"Millefeuille Technique" by Using Excised Intimal Layers in Repair of Type A Aortic Dissection.

Surgical outcomes for acute Type A aortic dissection (AAD) have dramatically improved in recent years due to prompt diagnosis, improved surgical technique and perioperative management. A single needle hole can become a new entry point in AAD cases with such a fragile wall, so a mixed technique using minimal surgical stitches and glue is required for a good outcome. The 'Millefeuille' technique involves multiple layers with a prosthetic graft, intimal layer, additionally inserted surplus intimal layer with BioGlue, adventitial layer, and felt.

Coronary artery aneurysm complicated by pneumothorax with a history of Kawasaki disease.

Kawasaki disease (KD) is a common vasculitis disorder of childhood. It can sometimes complicate coronary artery aneurysms, and treatment is required depending on the condition of stenosis. A 20-year-old man was referred for surgery with a coronary artery aneurysm and stenosis in the left coronary artery as sequelae of KD.

[Covering Suture Line Using Bovine Pericardium during Mitral Valve Replacement for Third Time Infectious Endocarditis;Report of a Case].

A 33-year-old man presenting with fever, fatigue, and delirium was diagnosed with infectious endocarditis(IE). He had already undergone surgery for IE twice;initial valve repair 4 years ago and mitral valve replacement(MVR) 1 year later. He has refractory atopic dermatitis, which was considered to be the cause of his repeated IE.

Cor triatriatum in adulthood with mitral valve regurgitation and atrial fibrillation.

Cor triatriatum is a rare congenital heart disease. A 57-year-old woman had cor triatriatum with severe mitral valve regurgitation (MR) and atrial fibrillation (AF). We performed mitral valve repair, left atrial appendage resection, and maze procedure by resection of the anomalous septum in the left atrium.

Total resection of an infected aortic arch aneurysm caused by Mycobacterium avium: a case report.

Background: Infected aortic arch aneurysms caused by Mycobacterium avium are rare in immunocompetent individuals. Promptly recognizing these aneurysms is important because delays in treatment result in aneurysm rupture and a high fatality rate. Although Salmonella species, Streptococcus species, Staphylococcus aureus, and S.

Spinal cord injury following aortic arch replacement.

Purpose: Postoperative spinal cord injury is a devastating complication after aortic arch replacement. The purpose of this study was to determine the predictors of this complication.

Methods: A group of 254 consecutive patients undergoing aortic arch replacement via median sternotomy, with (n = 78) or without (n = 176) extended replacement of the upper descending aorta, were included in a risk analysis.

Detection and genetic characterization of rotavirus infections in non-hospitalized children with acute gastroenteritis in Japan, 2007-2009.

The molecular epidemiology of rotavirus infections in non-hospitalized children in five different regions (Sapporo, Saga, Tokyo, Osaka, and Maizuru) of Japan during 2007-2009 was investigated. Overall, rotavirus was detected in 156 out of 1008 (15.5%) specimens.

In vivo temporal EPR study using a region-selected intensity determination method to estimate cerebral reducing ability in rats treated with olanzapine.

Region-selected intensity determination (RSID) is a method for obtaining the temporal changes in electron paramagnetic resonance (EPR) signal intensity from a target region, without the use of complicated procedures employed in the conventional imaging methods. An in vivo 700-MHz radio frequency EPR spectrometer equipped with a bridged loop-gap resonator was used with the RSID method to estimate intracerebral reducing ability in the rat following acute administration of olanzapine (OZP) or haloperidol (HPD). To this end, temporal changes in EPR signal intensity of target regions (the striatum and the prefrontal cortex) of rats which had received a blood-brain-barrier-permeable nitroxide radical (3-hydroxymethyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl) via an intravenous route were observed.

Genotypic linkages of VP4, VP6, VP7, NSP4, NSP5 genes of rotaviruses circulating among children with acute gastroenteritis in Thailand.

Rotavirus is the main cause of acute viral gastroenteritis in infants and young children worldwide. Surveillance of group A rotavirus has been conducted in Chiang Mai, Thailand since 1987 up to 2004 and those studies revealed that group A rotavirus was responsible for about 20-61% of diarrheal diseases in hospitalized cases. In this study, we reported the continuing surveillance of group A rotavirus in 2005 and found that group A rotavirus was detected in 43 out of 147 (29.

[Rotavirus vaccine].

Rotavirus gastroenteritis is one of the most important diseases in young children. There are 400,000 to 600,000 deaths annually among children under 5 years old in the world, especially in developing countries. Rotavirus vaccine has been developed since 1980s.

Diversification of transcriptional modulation: large-scale identification and characterization of putative alternative promoters of human genes.

By analyzing 1,780,295 5'-end sequences of human full-length cDNAs derived from 164 kinds of oligo-cap cDNA libraries, we identified 269,774 independent positions of transcriptional start sites (TSSs) for 14,628 human RefSeq genes. These TSSs were clustered into 30,964 clusters that were separated from each other by more than 500 bp and thus are very likely to constitute mutually distinct alternative promoters. To our surprise, at least 7674 (52%) human RefSeq genes were subject to regulation by putative alternative promoters (PAPs).

Species-specific but not genotype-specific primary and secondary isotype-specific NSP4 antibody responses in gnotobiotic calves and piglets infected with homologous host bovine (NSP4[A]) or porcine (NSP4[B]) rotavirus.

Using recombinant baculoviruses expressing rotavirus NSP4 [A], [B], [C], and [D] genotypes of bovine, porcine, human, simian, or murine origin, we analyzed serum antibody responses to NSP4s in gnotobiotic calves and piglets infected by the oral/alimentary or intraamniotic route with bovine (NSP4[A]) (Wyatt, R.G., Mebus, C.

Homotypic and heterotypic serum isotype-specific antibody responses to rotavirus nonstructural protein 4 and viral protein (VP) 4, VP6, and VP7 in infants who received selected live oral rotavirus vaccines.

Homotypic and heterotypic serum isotype-specific antibody responses to rotavirus enterotoxin nonstructural protein (NSP)-4, independent neutralization antigens viral protein (VP)-4 and VP7, and group A rotavirus common antigen VP6 were analyzed by an immunocytochemistry assay in infants who received 1 of several live oral rotavirus vaccines. Significant serum immunoglobulin (Ig) A and IgG antibody responses to homotypic and/or heterotypic NSP4s of genotype [A], [B], or [C] were detected after vaccination. The magnitude of antibody responses to homotypic and heterotypic NSP4s was not significantly different, irrespective of the NSP4 genotype of the administered vaccine strain.
