OBJECTIVES: Favourable outcomes in the repair of Ebstein's anomaly are predicated on tricuspid valve competence, right ventricular function and presence of arrhythmia. We report our experience with a single-stage, three-fold repair of Ebstein's anomaly, namely, cone reconstruction of the tricuspid valve supplemented by bidirectional cavopulmonary anastomosis and right atrial electrocautery maze. METHODS: From 2010 to 2014, 37 consecutive patients with Ebstein's anomaly, median age 17...

BACKGROUND: We have previously demonstrated that early primary repair of tetralogy of Fallot with pulmonary stenosis (TOF) can be safely performed without increase in hospital resource utilization or compromise to surgical technical performance scores (TPS). We sought to identify the optimal timing for elective early primary repair of TOF with respect to intermediate-term reintervention. METHODS: Retrospective review of all patients with TOF undergoing elective primary repair between September 2004 and December 2013 was performed...

BACKGROUND: The David V valve-sparing aortic root replacement (VSRR) is an established and durable method of root reconstruction for varying pathologies. However, the impact of the severity of preoperative aortic regurgitation (AR) on long-term durability remains unclear. The purpose of this research was to investigate the impact of the degree of preoperative AR on midterm durability following VSRR. METHODS: A retrospective review of the adult cardiac surgical database at a single academic center was undertaken from 2005 to 2015 for 223 adult patients who underwent VSRR...

BACKGROUND: Leaving native aortic tissue in situ in root-sparing ascending aortic replacement raises concern regarding potential later need for root reoperation or for the potential occurrence of localized dissections or rupture in the residual root. The purpose of this study was to evaluate the natural growth of the aortic root after root-sparing aortic replacement. METHODS: In all, 102 consecutive patients (mean age 61.8 ± 12.5 years; 60% male) who had undergone root-sparing aortic replacement had sufficient retrievable information regarding their aortic root diameter at postoperative baseline and follow-up imaging by computed tomography or echocardiography...

The Bentall procedure introduced in 1968 represents an undisputed cure to treat multiple pathologies involving the aortic valve and the ascending thoracic aorta. Over the years, multiple modifications have been introduced as well as a standardized approach to the operation with the goal to prevent long-term adverse events. The BioValsalva prosthesis provides a novel manner to more efficiently reconstruct the aortic valve together with the anatomy of the aortic root with the implantation of a valved conduit...

In a treatment planning study, radiosurgical treatment plans designed to produce lesions on the left atrium were created using two different methodologies. In one, structures in the heart (mitral valve and coronary arteries) were designated as critical structures while this was not done in the second plan. The treatment plans that were created were compared with standards for heart dose used when treating spine tumors. Although the dosage for the whole heart greatly exceeded the dose standards, when only the dose to the ventricles was considered, the plan where the mitral valve was spared was very close to the dose standards...

Management of aortic root pathology during repair of acute type A aortic dissection (TAAD) requires a comprehensive evaluation of the patient's anatomy, demographics, comorbidities and physiologic status at the time of emergent operative intervention. Surgical options include conservative repair of the root (CRR) (with or without replacement of the aortic valve), replacement of the native valve and aortic root using a composite valve-conduit and valve sparing root replacement (VSRR). The primary objective of this review is to provide data for surgeons to aid in their decision-making process regarding management of the aortic root during repair of TAAD...

Current surgical results of acute type A aortic dissection in Japan are presented. According to the annual survey by the Japanese Association of Thoracic Surgery, 4,444 patients with acute type A aortic dissection underwent surgical procedures and the overall hospital mortality was 9.1% in 2013. The prevalence of aortic root replacement with a valve sparing technique, total arch replacement (TAR), and frozen stent graft are presented and strategies for thrombosed dissection or organ malperfusion syndrome secondary to acute aortic dissection are discussed...

Acute type A aortic dissection (AcA-AoD) is a surgical emergency associated with very high morbidity and mortality. Unfortunately, the early outcome of emergency surgical repair has not improved substantially over the last 20 years. Many of the same debates occur repeatedly regarding operative extent and optimal conduct of the operation. The question remains: are patients suffering from too large an operation or too small? The pendulum favoring routine aortic valve resuspension, when feasible, has swung towards frequent aortic root replacement...

INTRODUCTION: Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. METHODS: From March/2012 thru March 2015, 37 patients consecutively underwent conservative operations of the aortic valve and/or aortic root. Mean age was 48±16 years and 81% were males...

We present a case of a young female with stroke symptoms who underwent valve sparing resection of a presumed fibroelastoma based on echocardiographic findings. After confirming embolic stroke, she underwent excision of the lesion, which on pathology revealed a nonbacterial thrombus. Ultimately, this led to a more extensive work-up leading to the discovery of a papillary serous ovarian carcinoma, the underlying cause of her hypercoagulable state. The initial echocardiographic findings painted the clear picture of a papillary tumor on the aortic valve which was likely the source of the emboli resulting in ischemic stroke...

OBJECTIVES: Repair for ischemic mitral regurgitation with undersized annuloplasty is characterized by high recurrence rates. We sought to determine the value of pre-repair 3-dimensional echocardiography over 2-dimensional echocardiography in predicting recurrence at 6 months. METHODS: Intraoperative transesophageal 2-dimensional echocardiography and 3-dimensional echocardiography were performed in 50 patients undergoing undersized annuloplasty for ischemic mitral regurgitation...

Giant cell arteritis is a common form of vasculitis, although involvement of the aorta is unusual. There is no established association between giant cell aortitis and human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection. We present the case of a 46-year-old female coinfected with HIV and HCV who had never received antiretroviral therapy and developed symptoms of deteriorating shortness of breath on exertion. Investigations demonstrated aortic root and ascending aorta dilatation, along with severe aortic valve regurgitation, for which the patient underwent valve-sparing aortic root replacement (a David procedure)...

The development of aortic valve-sparing operations (reimplantation of the aortic valve and remodeling of the aortic root) expanded the surgical armamentarium for treating patients with aortic root dilation caused by a variety of disorders. Young adults with aortic root aneurysms associated with genetic syndromes are ideal candidates for reimplantation of the aortic valve, and the long-term results have been excellent. Incompetent bicuspid aortic valves with dilated aortic annuli are also satisfactorily treated with the same type of operation...

BACKGROUND: Repair of tetralogy of Fallot (ToF) using a transannular patch can result in severe pulmonary insufficiency (PI) and subsequent right ventricular (RV) dilation. Use of a Dacron (Maquet Cardiovascular LLC, Wayne, NJ) limited transannular patch with nominal pulmonary annular expansion (LTAP) attempts to limit PI. We sought to evaluate the degree of PI and RV dilation resulting from a LTAP or annular sparing (AS) approach. METHODS: Infants less than 1 year of age undergoing ToF repair between 2000 and 2010 were divided into 2 groups: LTAP and AS RV outflow tract patch...

OBJECTIVES: An untreated dilated aortic annulus is a major risk factor for failure of aortic valve-sparing operations or repair of either bicuspid or tricuspid valve. Aortic annuloplasty efficiently reduces the annulus and increases the coaptation height, thus protecting the repair. This study analyses long-term results of 232 consecutive patients operated on with a standardized and physiological approach to aortic valve repair according to each phenotype of the dystrophic ascending aorta...

OBJECTIVES: In children, words of caution have been raised about valve-sparing procedures especially regarding the valve-remodelling technique. This study reviewed our experience with the valve-sparing reimplantation technique in children. METHODS: All consecutive paediatric (<18 years) patients who underwent valve-sparing root replacement in our centre in the past 12.5 years were retrospectively analysed. RESULTS: Nineteen patients (median age 13...

OBJECTIVE: The anatomically shaped sinus prosthesis (Uni-Graft W SINUS; Braun, Melsungen, Germany) used in valve-sparing aortic root replacement promises physiological hemodynamics believed to grant physiologic valve function. Using time-resolved 3-dimensional magnetic resonance phase contrast imaging (4D Flow MRI), we analyzed sinus vortex formation and transvalvular pressure gradients in patients with sinus prosthesis compared with age-matched and young healthy volunteers. METHODS: Twelve patients with sinus prosthesis (55 ± 15 years), 12 age-matched and 6 young healthy volunteers (55 ± 6 years, 25 ± 3 years, respectively) were examined at 3T with a 4D flow magnetic resonance imaging sequence...

BACKGROUND: We assessed whether additional cusp repair during valve-sparing aortic root replacement affects the echocardiographic mid-term results; a subgroup analysis among patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) was performed. METHODS: Between June 2002 and May 2015, 157 consecutive patients underwent valve-sparing aortic root replacement with the David technique. Thirty patients (19%) had BAV. In 19 patients (12%), cusp motion or anatomic abnormalities contributed in determining aortic regurgitation requiring an additional cusp repair...
