Importance: Internal nasal valve (INV) collapse is a common cause of nasal obstruction, and spreader grafts are the established standard of treatment. Recently, spreader flaps have gained attention in the treatment of nasal valve stenosis when performed in conjunction with dorsal hump reduction. To date, the efficacy of the spreader flap technique without dorsal hump reduction has not been previously described. Objective: To determine whether spreader flaps are equivalent to spreader grafts in correcting INV collapse in the absence of simultaneous dorsal hump reduction...

: Mitral stenosis is often managed percutaneously with an interventional procedure such as balloon commissurotomy. Although this often results in an increased mitral valve area and improved clinical symptoms, this procedure is not benign and may have serious complications including the development of hemodynamically significant mitral valve regurgitation. Multiple scoring systems have been developed to attempt to risk stratify these patients prior to their procedure. CASE: A 64-year-old patient underwent an emergent mitral valve replacement after having percutaneous mitral balloon commissurotomy complicated by development of severe mitral regurgitation...

REVIEW
Yousif Ahmad, Michael F Bellamy, Christopher S R Baker
Aortic valve stenosis occurs 10-20 years earlier in patients on dialysis compared with the general population. This is likely related to the exposure of the valve to a milieu that predisposes to calcification as well as increased shear stress across the valve. Objective assessment of stenosis severity is largely made using echocardiography though accurate interpretation requires an understanding of the potential pitfalls of the technique and the influence of cardiac output upon the gradient measured across the valve...

Situs inversus totalis and anomalous origin of the left coronary artery are rare conditions. An 87-year-old woman with both conditions presented to the authors' hospital with symptomatic aortic stenosis. She underwent aortic valve replacement (AVR) and coronary artery bypass grafting (CABG; saphenous vein graft to the left main trunk). The operator mainly stood on the left side of the patient and performed surgery without difficulty. Both, AVR and CABG were successfully performed despite these two rare conditions...

The aim of this review was to describe recent advancements in the understanding of bicuspid aortic valve (BAV). BAV is the most common congenital cardiac anomaly, and affects between 0.46% and 1.37% of the population. There is a male predominance of approximately 3:1.While isolated BAV is found in certain patients, it is often associated with other congenital cardiac lesions, including dilatation of the thoracic aorta, coarctation of the aorta and abnormalities of the coronary anatomy. In most cases, it remains undetected until the patient contracts infective endocarditis, or calcification occurs...

Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for patients with severe aortic stenosis (AS) who are unsuitable for surgical aortic valve replacement (SAVR), and is an acceptable alternative for those at high and intermediate surgical risk. In published TAVI registries and meta-analyses, whilst women are significantly older they present with fewer comorbidities compared to men (including coronary artery disease, peripheral vascular disease, diabetes and chronic obstructive pulmonary disease)...

BACKGROUND: Prosthesis-patient mismatch (PPM) is highly prevalent among patients undergoing aortic valve replacement (AVR) to treat aortic stenosis. Data regarding the prevalence and impact of PPM on left ventricular remodeling and outcomes in patients who have undergone surgical AVR to treat pure severe aortic regurgitation (AR) are, however, scarce. METHODS: A retrospective analysis was conducted of clinical and echocardiographic data acquired from 50 consecutive patients with pure severe AR, without evidence of significant coronary artery disease, who underwent AVR between 2004 and 2010 at the authors' institution...

BACKGROUND: Controversy exists regarding the potential effects of lipid metabolism on the expression of proximal aortopathy. The study aim was to compare the association between markers of lipid metabolism and the expression of proximal aortopathy in patients with either bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) disease. METHODS: A total of 458 consecutive patients (68% males) underwent aortic valve replacement (AVR) with or without concomitant aortic surgery between January 2008 and December 2014 at the authors' institution...

Pulmonary regurgitation and/or stenosis (PS) is challenging in patients with congenital heart defects. Our aim was to identify if criteria for referral were different between surgical (SPVR) and transcatheter pulmonary valve replacement (TPVR) populations, and to further assess if any baseline differences influence the resultant ventricular remodeling at medium-term follow-up. Retrospective chart review of patients post-SPVR or TPVR at our center from 2013 to 2015 was conducted. Volumetric data from cardiac magnetic resonance (CMR), 1 year before and 1 year after PVR was obtained...

OBJECTIVES: Although transcatheter aortic valve replacement (TAVR) is an excellent alternative procedure for high-risk patients with severe symptomatic aortic stenosis, it is often associated with life-threatening complications. We report on the emergency or elective use of veno-arterial extracorporeal membrane oxygenation (ECMO) to manage these complications. METHODS: Between December 2013 and February 2016, 46 patients underwent TAVR at our institution. Of these, 4 patients required emergency ECMO support and another 3 patients were electively placed on ECMO support at the start of the procedure...

The mitral valve disease (MVD) in Lutembacher's syndrome has been infrequently analyzed from a pathological standpoint. In this study, we have attempted to elucidate the pathology of MVD in this interesting syndrome in 44 autopsied cases of combined non-primum atrial septal defect (ASD) and MVD collected over 16 years. The patients were divided into 3 groups: Group 1: non-primum ASD with clinically diagnosed mitral stenosis (MS)±regurgitation, Group 2: non-primum ASD with clinically diagnosed mitral regurgitation (MR) and, Group 3: non-primum ASD with no clinically evident MVD, but with mitral valve pathology diagnosed at autopsy...

BACKGROUND: Right ventricular (RV) dysfunction was shown to be associated with adverse outcomes in a variety of cardiac patients and is considered a risk factor for adverse outcome according to the updated Valve Academic Research Consortium criteria. OBJECTIVE: Our goal was to assess the impact of RV function at baseline on 1-year mortality among patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). METHODS: All patients with severe AS treated with TAVR from May 2007 to March 2015 at our center were included in the present study, and baseline and procedural characteristics were recorded for each patient...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

BACKGROUND: Left bundle branch block (LBBB) is common following trans-catheter aortic valve replacement (TAVR) and has been linked to increased mortality, although whether this is related to less favourable cardiac reverse remodeling is unclear. The aim of the study was to investigate the impact of TAVR induced LBBB on cardiac reverse remodeling. METHODS: 48 patients undergoing TAVR for severe aortic stenosis were evaluated. 24 patients with new LBBB (LBBB-T) following TAVR were matched with 24 patients with a narrow post-procedure QRS (nQRS)...

A 43-year-old female patient with mitral valve stenosis and hypereosinophilia on admission received mechanical mitral valve replacement. During the 2 years after the first surgery, the patient underwent two mitral valve revision operations for repeated prosthetic mitral valve thrombosis. During the 2-year period, the patient's absolute eosinophil count was found elevated repeatedly. Finally, fluke antibody detection revealed fluke infection and, after praziquantel treatment, a normal level of absolute eosinophil count has been maintained and recurrent thrombosis has not occurred for 18 months...

Immunoglobulin G4-related systemic disease (IgG4-RSD) is a recognized emerging entity characterized by chronic fibroinflammation that can affect every organ but rarely affects the cardiovascular system. We report a rare case of IgG4-RSD involving an aortic valve that resulted in rapid progression of an aortic valvular stenosis and was successfully treated by aortic valve replacement and corticosteroids.
