Although pressure-overload right ventricular hypertrophy is a long-term risk in some congenital heart diseases such as tetralogy of Fallot, how it develops unclear. The aim this study was to investigate the mechanism development failure.Pulmonary artery banding 10-day-old rabbits induced they grew. Comparisons were made with age-matched sham controls (n = 24 per group). In weekly serial echocardiography, contraction and diastolic function decreased from 3 weeks after surgery (P < 0.01),...

Abstract OBJECTIVES We conducted this case series to evaluate the feasibility and mid-term outcomes of orthotopic aortic arch reconstruction using xenopericardial grafts treat native arch/arch graft infection. METHODS Between 2010 2023, adopting a multidisciplinary approach, we treated consecutive patients with infection by branched roll replacement tissue filling. The end points study were reinfection graft-related complications such as pseudoaneurysm formation, thromboembolism, stenosis,...

Abstract Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heart muscle disorder characterized by enlargement, failure (HF), and arrhythmias which lead to sudden death especially in young adults. Current recommendations for management of patients with ARVC are antiarrhythmic medications, catheter ablation, implantable cardioverter defibrillator therapy prevent cardiac death. However, despite these treatments, few suffer from recurrent or HF unresponsive conventional management....

Atypical aortic coarctation (AAC) has been reported to occur anywhere along the aorta, except for ascending aorta. The associated symptoms include hypotension in lower half of body, secondary hypertension upper and heart failure. Here we present an 80-year-old Asian woman complaining progressive exertional dyspnea. She was diagnosed with acute decompensated failure kidney injury due severely calcified stenosis thoracoabdominal so called AAC. received hemodiafiltration, pulmonary congestion...

We previously demonstrated that infrared coagulator IRK-151 (Lumatec, Deisenhofen, Germany) is capable of creating a transmural lesion while preserving the epicardium and endocardium beating right atrium ventricle in canine model (1). Since original contains 3-sec timer its plastic body not strong enough to tolerate long coagulation times, we modified it by replacing with reinforced heat-resistant substituting digital programmable so would be perform myocardial ablation, conduction block on...

Central MessageThis is the first report showing a large vegetation on an elephant trunk using xenopericardial roll graft that almost totally occludes lumen during late postoperative period.See Commentaries pages 50 and 52. This period. See Elephant (ET) infection rare complication.1Tanaka A. Sakamoto T. Okada K. Okita Y. Vegetation attached to trunk.Eur J Cardiothorac Surg. 2013; 44: 565-566Crossref PubMed Scopus (3) Google Scholar We present uncommon case of ET, which occluded A 72-year-old...

The increasing use of total arch replacement and frozen elephant trunk (FET) is expected to lead an increase in the prevalence graft infections requiring involving FET, which generally a more invasive procedure than initial surgery. Herein, we describe novel method for FET removal using polyvinyl tube as storage device. completed same median sternotomy approach We report on outcomes six patients. Our simple perform safe caused no injury aorta our case series.

Abstract Background Creating a box lesion in the posterior wall of left atrium from epicardial side beating heart remains challenge. Although transmural can be created by applying radiofrequency (RF) energy at clampable sites, it is still difficult to create unclampable sites because inner blood flow free weakens thermal effect on outside. Our aim was apply newly developed infrared coagulator linear lesions thoracoscopically treat atrial fibrillation (AF). Case presentation A 71-year-old...

Hemoptysis is a rare complication of acute aortic dissection. A 77-year-old woman was admitted to our department with epigastralgia and hemoptysis. Computed tomography showed Stanford dissection massive posterior mediastinal hematoma which extended along the right pulmonary artery. lethal sign dissection, therefore, emergency ascending replacement performed good clinical outcome.

A three-month-old boy with hypoplastic left heart syndrome (mitral atresia, aortic atresia) and moderate tricuspid regurgitation developed ascending aorta obstruction two months after a Norwood stage I procedure. An emergent mammary artery bypass grafting to the extracorporeal membrane oxygenator support resulted in successful salvage. The patient subsequently underwent bidirectional Glenn procedure valve repair at age of five months. Follow-up an outpatient clinic reveals no...

Abstract Background Persistent blood flow is common in aortic aneurysms following endovascular repair. However, the recanalization of thrombosed intercostal arteries after open repair rare. We report a case aneurysm recurrence 11 years thoracoabdominal replacement resulting from like type II endoleak patient with Marfan syndrome. Case presentation A 50-year-old woman syndrome presented left-sided back pain meals. She underwent abdominal at 35 age, distal arch and for B chronic dissection 38...

Introduction With advancement of continuous flow ventricular assist device (Cf-VAD) technology, implantation and longer support has been becoming safer safer. Miniaturization also allowed us to implant cf-VAD in patients with small body size. There is still some concern about stable safe We sought analyze our implantations for bridge transplantation (BTT) see if there was any difference survival or complication rates by the Material Methods analyzed 148 consecutive BTT (age: 39.7 years, 41...

Abstract Introduction; Despite its rapid technological development and widespread uptake for thoracic aortic disease, an extremely tortuous anatomy is considered a contraindication endovascular repair procedure. We report case of successful using techniques to straighten aorta friendly. Case Presentation; A 78-year-old man with frequent surgical history was admitted our outpatient clinic because dyspnea back pain. Enhanced computed tomography scan revealed type Ib endoleak, acute enlargement...

Abstract BackgroundCreating a box lesion in the posterior wall of left atrium from epicardial side beating heart remains challenge. Although transmural can be created by applying radiofrequency (RF) energy at clampable sites, there is still no reliable source to use create roof and bottom linear connect bilateral pulmonary vein (PV) cuff lesions produced with RF energy, because inner blood flow unclampable free weakens thermal effect on outside. Our aim was apply newly developed infrared...
