BACKGROUND: Patients undergoing hybrid aortic arch reconstruction require careful protection of vital organs. We believe that whole body perfusion with tailored dual circuitry may help to achieve optimal patient outcomes. METHODS: Our circuit has evolved from a secondary circuit utilizing a cardioplegia delivery device for lower body perfusion to a dual-oxygenator circuit. This allows individually controlled regional perfusion with ease of switching from secondary to primary circuit for total body flow...

BACKGROUND: Although aortic valve-sparing (AVS) operations are established alternatives to composite valve graft (CVG) procedures for patients with aortic root aneurysms, comparative long-term outcomes are lacking. OBJECTIVES: This study sought to compare the results of patients undergoing AVS procedures with those undergoing CVG operations. METHODS: From 1990 to 2010, a total of 616 patients age <70 years and without aortic stenosis underwent elective aortic root surgery (AVS, n = 253; CVG with a bioprosthesis [bio-CVG], n = 180; CVG with a mechanical prosthesis [m-CVG], n = 183)...

We report the case of a patient with situs inversus totalis, annuloaortic ectasia complicated by aortic insufficiency and mitral regurgitation which induced congestive heart failure. Both valvular lesions were repaired physiologically using aortic root sparing Yacoub 'remodeling' technique and mitral ring annuloplasty. Valve sparing techniques can be used effectively even in patients with complicated clinical scenarios (like dextrocardia and annuloaortic ectasia) to avoid the potential risks related to prosthetic valve implantation and lifelong anticoagulation therapy...

OBJECTIVES: Treatment of infected thoracic aortic grafts is associated with considerable morbidity and mortality. The replacement of an infected graft is an effective strategy, yet a complex surgical endeavour, especially if the aortic root or aortic arch is involved. In situ graft-sparing surgical therapy with continuous mediastinal irrigation after surgical debridement might offer an alternative in the management of early graft infections in the thoracic aorta. METHODS: Between 1996 and August 2015, 25 patients were treated in our institution for early graft infection after thoracic aortic surgery via sternotomy...

BACKGROUND: Surgery of the aortic arch is challenging. AIM: To assess the results of aortic arch surgery. METHODS: Analysis of 172 patients operated on arch dissection (emergency group: 97 patients) or aneurysm (elective group: 75 patients) between 2007 and 2014. Arch surgery was defined as a procedure requiring circumferential anastomosis at the level of the aortic arch or the descending aorta with the use of techniques of brain protection (deep hypothermic circulatory arrest [DHCA] or selective antegrade cerebral perfusion [SACP]) and/or debranching of at least one supra-aortic vessel...

BACKGROUND: In patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve-sparing surgery (with regards to the age of the patient), Ross procedure and mechanical aortic valve replacement. METHODS: Quality of life was studied in 139 patients after aortic valve surgery divided into four study groups (Y - aortic valve-sparing procedure at the age below 50 years, mean age 36...

BACKGROUND AND AIM OF THE STUDY: Bicuspid aortic valve (BAV), though normally functioning, is frequently associated with dilatation of the aortic root and ascending aorta. Optimal surgical treatment remains controversial. The study aim was to evaluate the fate of the normally functioning spared BAV at long-term follow up. METHODS: Forty patients (26 males, 14 females; mean age 59 +/- 11 years; range: 38-81 years) who underwent aortic surgery for proximal aortic disease between 1996 and 2011, with spared BAV at surgery, were included in the study...

PURPOSE OF REVIEW: In the past year, there has been progress on several fronts in the field of mitral valve surgery and intervention. Here, we review key publications regarding the surgical and transcatheter management of mitral valve disease. RECENT FINDINGS: This past year heralded the publication of the 2014 American Heart Association (AHA)/American College of Cardiology (ACC) Guidelines for the Management of Patients With Valvular Heart Disease. Regarding degenerative mitral regurgitation, low risk of operative mortality and data demonstrating clinical benefit for early surgery are prompting renewed calls for early intervention before guideline-based triggers...

Elective root replacement in Marfan syndrome has improved life expectancy in affected patients. Three forms of surgery are now available: total root replacement (TRR) with a valved conduit, valve sparing root replacement (VSRR) and personalised external aortic root support (PEARS) with a macroporous mesh sleeve. TRR can be performed irrespective of aortic dimensions and a mechanical replacement valve is a secure and near certain means of correcting aortic valve regurgitation but has thromboembolic and bleeding risks...

BACKGROUND: Valve sparing aortic root reconstruction (VSARR) has become an alternative to traditional aortic root replacement with a valved conduit. There have been various modifications but the two broad types are aortic root reimplantation and the aortic root remodelling procedure. We present the early and late outcomes following valve sparing aortic root reconstruction surgery in Australia. METHODS: We reviewed the ANZSCTS database for patients undergoing these procedures...

OBJECTIVES: Dilatation of the aortic annulus is a cause of recurrent aortic regurgitation following the Ross or Yacoub procedures. Use of an extra-aortic annuloplasty ring is a potentially useful adjunct procedure. The aim of this study was to analyze the early effectiveness and mid-term stability of this surgical approach. METHODS: From 2011 to 2015, 50 patients (mean age, 43 ± 14 years) underwent adjunct extra-aortic annuloplasty ring implantation (n = 39 Dacron rings and n = 11 ExAo rings [CORONEO Inc, Montreal, Canada])...
