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...

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)...

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...

BACKGROUND: Although practice guidelines recommend surgery for patients with severe chronic ischemic mitral regurgitation (CIMR), they do not specify whether to repair or replace the mitral valve. The purpose of this study was to evaluate the long-term outcomes in patients with severe CIMR undergoing mitral valve annuloplasty (MVA) versus subvalvular sparing mitral valve replacement (MVR). METHODS: 392 consecutive patients who underwent MVA or subvalvular sparing MVR for treatment of severe CIMR were retrospectively reviewed...

In patients with aortic regurgitation (AR), a precise preoperative assessment of aortic valve (AV) pathology is important if AV repair or sparing operation is an alternative option. The aim of this study was to assess the diagnostic accuracy of computed tomography (CT) for evaluating the AR mechanism compared with surgical inspection. 59 patients with AR who underwent AV surgery and preoperative cardiac CT were evaluated. AR mechanism was classified into type 1 (aortic dilatation or cusp perforation), type 2 (prolapsed cusp) and type 3 (cusp retraction)...

OBJECTIVES: Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. METHODS: Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively...

Valve-sparing root replacement is increasingly used to overcome drawbacks associated with valvular prostheses. In our institution, 7 patients underwent valve-sparing root replacement from August 2016 to July 2017. The mean age was 45 years (range, 14~69 years). Three patients had Marfan syndrome and 1 had Loeys-Dietz syndrome with acute aortic dissection. All patients underwent surgery with reimplantation technique using a Valsalva graft. Two patients required repair of aortic valve leaflet prolapse. All patients had an excellent clinical course, with mild or no aortic regurgitation and a decrease in end-diastolic volume on echocardiography...

This case study reports the successful implantation of the Xen ab interno gel stent in a 44-year-old man with refractory chronic open-angle glaucoma. The patient had multiple unsuccessful filtration surgeries including a trabeculectomy and 2 Ahmed glaucoma valves placed superotemporally and inferonasally oculus dexter. 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 intraocular pressure in patients with refractory glaucoma, despite previous filtration surgeries if the superonasal conjunctiva is spared and healthy...

OBJECTIVES: The significant morbidity of long-term pulmonary regurgitation (PR) has driven the development of pulmonary valve (PV) sparing repair strategies in patients with tetralogy of Fallot (ToF). We assessed mid-term PV function in patients who underwent primary ToF repair with valve-sparing intraoperative balloon dilation (IBD) technique. METHODS: We evaluated 162 consecutive patients with ToF and pulmonary stenosis (ToF-PS) who underwent valve-sparing repair with IBD under 1 year of age...
