OBJECTIVES: Remodelling with extra-aortic ring annuloplasty has emerged as an alternative approach to root reimplantation. However, no studies have yet compared outcomes between procedures. The aim of this study was to compare mid-term outcomes in patients undergoing reimplantation versus remodelling with extra-aortic annuloplasty. METHODS: From 2001 to 2017, 142 patients underwent root remodelling with extra-aortic annuloplasty (n = 83, 48 ± 13 years) or a reimplantation technique (n = 59, 48 ± 12 years) at the Montreal Heart Institute...

BACKGROUND: Right ventricular (RV) volume overload increases morbidity and mortality after tetralogy of Fallot (TOF) repair. Surgical strategies like pulmonary leaflets sparing and tricuspid valve repair at time of primary repair may decrease RV overload. Our objective is to evaluate early and midterm results of pulmonary leaflets sparing with infundibular preservation and tricuspid valve repair in selected TOF patients with moderate pulmonary annular hypoplasia. METHODS: From 2011 to 2016; 46 patients with TOF and moderate pulmonary annular hypoplasia had surgical repair with sparing of the pulmonary valve leaflets...

INTRODUCTION: Life expectancy in young adults undergoing mechanical or bioprosthetic aortic valve replacement (AVR) may be reduced by up to 20 years compared to age matched controls. The Ross procedure is a durable, anticoagulation-sparing alternative. We performed a systematic review and meta-analysis to compare the valve hemodynamics of the Ross procedure versus other AVR. EVIDENCE ACQUISITION: We searched Cochrane CENTRAL, MEDLINE and EMBASE from inception to February 2017 for randomized controlled trials (RCTs) and observational studies (n≥10 Ross)...

This case study reports the successful implantation of the Xen ab interno gel stent in a 44-year-old male with refractory chronic open angle glaucoma. The patient had multiple unsuccessful filtration surgeries including a trabeculectomy and two Ahmed glaucoma valves placed superotemporally and inferonasally OD. The patients intraocular pressure was reduced from 29▒mm Hg preoperatively to 17▒mm Hg 1 year after surgery, without any ocular complications. The Xen gel stent may be considered as a possible intervention to lower IOP in patients with refractory glaucoma, despite previous filtration surgeries if the superonasal conjunctiva is spared and healthy...

Despite the obvious advantages of the preservation of a normal aortic valve during aortic root replacement, the complexity of valve sparing procedures prevents a number of cardiac surgeons from incorporating them into their practice. The aim of this protocol is to describe a simplified and user-friendly technique of an aortic valve-sparing root replacement (VSRR) procedure by re-implantation of the aortic valve. Proper selection of patients and limitations of the technique are discussed. In 54 consecutive patients, normal appearing aortic valves were re-implanted in a commercially available polyester prosthesis with pre-shaped sinuses by a simplified and standardized technique...

Hammock mitral valve (MV), also known as anomalous mitral arcade, is a rare congenital anomaly. We report a case of a 10-month-old child who presented with congestive heart failure and was found to have severe mitral stenosis (MS) secondary to a hammock MV anomaly. Detailed advanced imaging with cardiac MRI and three-dimensional (3D) echocardiography favorably navigated a customized valve-sparing surgical reconstruction of the congenitally abnormal MV. Repair of a hammock MV is technically difficult with a guarded prognosis...

BACKGROUND: Annulus-sparing (AS) repair of tetralogy of Fallot (TOF) carries a potential increased risk reoperation for re-stenosis and unproven benefits on right ventricular (RV) geometry. METHODS: Primary TOF repairs (N=434) between 2000 and 2012 were studied using risk-adjusted parametric techniques. Progression of cardiac dimensions were analyzed using repeated measures regression using reports of all 2,103 echocardiograms undertaken throughout the study period, to maximum follow-up 13...

Background: It is recommended that dilated ascending aortas (≥45 mm) should be replaced at the time of aortic valve replacement (AVR) for bicuspid aortic valve (BAV). The risk of progressive sinus of Valsalva dilatation after AVR and ascending aorta replacement is less clear. Methods: We identified 156 patients (age 56.2±10.8 years, 46 females) who underwent AVR and ascending aorta replacement in our institution from 2010-2014, 124 (79%) of whom had BAV. Aortic root and ascending aorta sizes were determined from preoperative and the most recent echocardiograms...
