Aortic root aneurysm is the most common cardiovascular manifestation requiring surgical intervention in patients with Marfan syndrome (MFS), a heritable thoracic aortic disease. Elective replacement of the aortic root is the treatment of choice for patients with aneurysmal complications of the aortic root and ascending aorta. There are two basic approaches to aortic root replacement: valve-sparing (VS) and valve-replacing (VR) techniques. After successful aortic root replacement surgery, several patients with MFS may develop a late complication related to their aortic disease process, such as developing a pseudoaneurysm of the coronary artery reattachment buttons, aneurysmal expansion, or aortic dissection in the remaining native aorta...

We investigated long-term functional changes in the kidney and bladder of patients with posterior urethral valve (PUV) who underwent fetal intervention or postnatal surgery.We retrospectively reviewed the medical records of 28 consecutive patients treated for PUV at our institution. Detailed data on medical and surgical histories, particularly on pre- and postnatal treatment modality, including fetal vesicoamniotic shunt, endoscopic valve ablation, and vesicostomy, were collected and analyzed. Long-term renal function was evaluated based on serum levels of creatinine (sCr), estimated glomerular filtration rate (eGFR), and renal scans...

BACKGROUND: To assess early and late clinical outcomes in patients who underwent aortic valve repair or aortic valve sparing surgery, and to investigate predictors for failure. METHODS: Of 227 consecutive patients who underwent aortic valve repair or sparing surgery in our department between 2004 and 2016, 81(36%) underwent aortic root replacement with or without cusp repair, 97(42%) ascending aorta replacement with or without cusp repair, and 49 (22%) isolated aortic valve repair...

Mixed connective tissue disease (MCTD) syndrome in children may lead to large aortic aneurysms, which in turn pose a difficult surgical problem. Valve-sparing root replacement is not always a viable option as the disease process invariably affects the aortic valve leaflets. Among pediatric patients, the Ross procedure is contraindicated on account of weakness of the pulmonary root, while Bentall surgery is the 'gold standard' treatment of aortic aneurysm, with reproducible and excellent long-term results. The case is presented of a three-year-old girl with a large thoracic aortic aneurysm in whom Bentall's surgery was performed, with a good result...

A thorough understanding of the well-functioning, native aortic root is pivotal in an era, where valve sparing surgical techniques are developed and used with increasing frequency. The objective of this study was to characterize the local structural stiffness of the native aortic root, to create a baseline for understanding how different surgical interventions affect the dynamics of the aortic root. In this acute porcine study (N = 10), two dedicated force transducers were implanted to quantify the forces acting on both the annular plane and on the sinotubular junction (STJ)...

BACKGROUND: A sternal-sparing approach to surgery of the proximal aorta could decrease postoperative morbidity. METHODS: To determine the potential benefits of using a minimally invasive right thoracotomy approach for the treatment of ascending aortic pathology, we retrospectively reviewed our experience in patients who required circulatory arrest for the treatment of ascending aortic pathology (with or without aortic valve involvement) between January 2009 and November 2014 (N=177)...

BACKGROUND: Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder predisposing patients to aneurysm formation and arterial dissection. Aortic root replacement is often performed prophylactically and valve-sparing root replacement (VSRR) has become the procedure of choice. However, in these patients with connective tissue disorders, postoperative pseudoaneurysms may develop. METHODS: All children with LDS undergoing VSRR at a single institution were retrospectively reviewed to identify patients who developed postoperative pseudoaneurysms...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

INTRODUCTION: Bicuspid aortic valve (BAV) is the single most common cardiac congenital mal-formation with a prevalence of 1-2%. It is frequently associated with aortic disease including annular ectasia. Increasing evidence suggests that valve-sparing root re-implantation surgery combined with primary aortic valve repair can be performed with good midterm results in patients with BAV. METHODS: Our objective is to compare the short and long term results of David procedure in BAV patients with aortic root ectasia...

OBJECTIVE: The size of the pulmonary annulus measured as a z-score is often used to determine when to insert a transannular patch (TAP). Multiple "cutoffs" are quoted in the literature; this could lead to inappropriate insertion. We aimed to determine whether the use of z-scores derived from different populations may have contributed to the varied "cutoffs" quoted. METHODS: PubMed was searched using the terms: "tetralogy," "Fallot," "transannular," "patch," "mortality," and "death...

We retrospectively reviewed the indications and outcomes of ileal-ureter substitution cases for complex ureteral reconstruction. We analyzed the patient clinical characteristics, outcomes, and complications of eight patients who had ileal ureter substitution surgery at Kyoto University Hospital between 2009 and 2016. The median patient age was 55.5 years (36-79), and the median follow up period was 25.5 months (7-85). Seven patients had unilateral ureteral obstruction (right:left=4:3), and one had bilateral ureteral obstruction...

Aortitis is an infrequent cause of aortic root dilatation and aortic valve regurgitation. Valve-sparing procedures have been proposed, but there is not clear evidence of which is the treatment of choice. We report the case of a 38-year-old pregnant lady with a diagnosis of idiopathic aortitis associated with aortic root aneurysm and severe aortic valve regurgitation.

Background: Patients with annuloaortic ectasia may be surgically treated with modified Bentall or David I valve-sparing procedures. Here, we compared the long-term results of these procedures. Methods: A total of 181 patients with annuloaortic ectasia underwent modified Bentall (102 patients, Group 1) or David I (79 patients, Group 2) procedures from 1994 to 2015. Mean age was 62 ± 11 years in Group 1 and 64 ± 16 years in Group 2. Group 1 patients were in poorer health, with a lower ejection fraction and higher functional class...

A 58-year-old African American female, who had previously undergone a valve-sparing aortic root replacement for a type A dissection, represented 2 months later with a new focal dissection and aneurysm with intramural hematoma just distal to the origin of the left subclavian artery. Since no landing zone distal to the subclavian artery existed, the patient underwent thoracic endovascular aortic repair with laser fenestration-aided stent-graft placement in the left subclavian artery. The patient recovered without complication, and 52 months later, she is doing well with normal renal function and ambulatory status...

BACKGROUND: This study aimed to evaluate the clinical outcomes of aortic root replacement(ARR) surgery:Root reimplantation as valve-sparing root replacement(VSR) and the Bentall procedure. METHODS: We retrospectively reviewed 216 patients who underwent ARR between 1995 and 2013 at Samsung Medical Center. Patients were divided into two groups, depending on the procedure they underwent: Bentall(n=134) and VSR(n=82). The mean follow-up duration was 100.9±56.4 months...

We describe a case of Type A aortic dissection in a 25 year old lady who had undergone a Ross Procedure for aortic valve endocarditis 13 years previously. She was pregnant and noted to have significant enlargement of the aortic root during the latter portion of the third trimester of her pregnancy. An echocardiogram performed after delivery demonstrated new aortic valve insufficiency in addition to an aortic root diameter of 6.5 cm. A CT angiogram demonstrated a Type A aortic dissection involving only the very proximal portion of the ascending aorta...
