OBJECTIVES: If the aortic root dilates after native aortic valve-sparing root reconstruction with remodeling, aortic regurgitation may recur. However, it has not been demonstrated clearly that the aortic root dilates after remodeling. METHODS: This study enrolled 15 patients who underwent an aortic valve-sparing operation with remodeling (2002-2014) but without any ventriculo-aortic junction (VAJ) fixation. Technically, special care was taken to pass the sutures through the fibrous annulus...

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...

Standard aortic valve replacement for aortic regurgitation caused by Behçet's disease is frequently complicated by postoperative recurrent prosthetic valve detachment. To prevent this, we have developed a modified Bentall procedure, in which the valved conduit is proximally attached to the left ventricular outflow tract instead of to the fragile annulus, based on the fact that the left ventricular outflow tract myocardium is rarely involved in Behçet's disease. This modified Bentall procedure was performed in 5 Behçet's disease patients with prosthetic valve detachment after primary aortic valve replacement, and satisfactory results were achieved...

BACKGROUND: Aortic valve predilation with balloon aortic valvuloplasty (BAV) is recommended before transcatheter aortic valve implantation (TAVI), despite limited data around the requirement of this preprocedural step and the potential risks of embolization. This study aimed to investigate the trends in practice and associations of BAV on short-term outcomes in the UK TAVI registry. METHODS AND RESULTS: Eleven clinical endpoints were investigated, including 30-day mortality, myocardial infarction, aortic regurgitation, valve dysfunction, and composite early safety...

REVIEW
W Randolph Chitwood
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

BACKGROUND: Robotic mitral valve (MV) repair is the least invasive surgical approach to the MV and provides unparalleled access to the valve. We sought to assess technical aspects and clinical outcomes of robotic MV repair for isolated posterior leaflet prolapse by examining the first 623 such cases performed in a tertiary care center. METHODS: We reviewed the first 623 patients (mean age 56±9.7 years) with isolated posterior leaflet prolapse who underwent robotic primary MV repair from 01/2006 to 11/2013...

BACKGROUND: Mitral valve cleft (MVC) is the most common cause of congenital mitral insufficiency, and MVC may occur alone or in association with other congenital heart lesions. Direct suture and valvuloplasty are the major and effective treatments for mitral regurgitation (MR) caused by MVC. Therefore, it is important to determine the location and magnitude of the pathological damage due to MVC when selecting a surgical procedure for treatment. This study explored the application value of transthoracic real-time 3-dimensional (3D) echocardiography (RT-3DE) in the diagnosis of MVC...

BACKGROUND: Bicuspid aortic valve (BAV) is associated with asymmetric dilatation of the proximal ascending aorta. We previously demonstrated increased susceptibility of smooth muscle cells to oxidative stress in the BAV-aneurysmal aorta and hypothesized that antioxidant expression is regionally defined and influenced by the BAV morphotype. METHODS: BAV valve morphology was defined according to number of raphes: type 0 (0 raphes), type 1 (1 raphe), or type 2 (2 raphes) and by the raphe location among the left (L), right (R) or non (N) coronary cusps...

Situs inversus totalis and mirror-image dextrocardia is a rare congenital anomaly. A 79-year-old man with a history of atrial fibrillation presented to our hospital with chest oppression. Chest X-ray and computed tomography showed mirror-image dextrocardia and situs inversus totalis. Echocardiography revealed severe mitral and aortic regurgitation and mild tricuspid regurgitation. Mitral and aortic valve replacement using bioprosthesises, tricuspid annuloplasty and closure of the left atrial appendage were successfully performed...

A 40-year-old man underwent 4 aortic surgeries because of endocarditis and subsequent prosthesis dehiscence. At the last recurrence he presented with acute severe aortic regurgitation of a Pericarbon Freedom (LivaNova plc, London, UK) stentless bioprosthesis and a morphologically disarranged aortic root. He also presented with left ventricular dysfunction and a very low origin of the left coronary artery. Therefore, a fifth redo aortic valve replacement was considered at high surgical risk. Accordingly, before listing the patient for a heart transplantation, a transcatheter valve-in-valve implantation with the JenaValve (JenaValve Technology, GmbH, Munich, Germany) prosthesis was performed...

OBJECTIVE: Bicuspid aortic valve anatomy is associated with ascending aortic aneurysm in approximately 50% of individuals and may lead to severe aortic regurgitation with aortic dilatation. Both entities may be treated by valve repair and root remodeling. The objective was to review the cumulative experience of 20 years. METHODS: Between November 1995 and December 2015, 357 patients (324 male; age 10-80 years; mean, 49 ± 13 years) underwent combined bicuspid aortic valve repair and root remodeling...

OBJECTIVES: To describe the feasibility and safety of the Hopscotch Technique, a novel method to close paravalvular leaks. BACKGROUND: Successful closure of paravalvular leaks requires the complete seal of irregular defects, frequently interrupted by remaining sutures or tissue that converts a large defect into a complex series of contiguous smaller defects. Successful treatment with devices placed in a single space is impossible with constrained appearance and significant residual leak; therefore, new techniques to deploy smaller devices in the correct location are needed...

Besides association with acute rheumatic fever (ARF) and acute glomerulonephritis (APSGN), in up to 40% of cases, Group A β-haemolytic streptococcal (GABHS) infections are also implicated as a trigger for Henoch-Schonlein purpura (HSP). A 7-year-old girl with GABHS throat infection who developed HSP, APSGN and rheumatic carditis is reported. She presented with palpable purpura and arthritis in both ankles and later developed carditis characterised by mitral/aortic regurgitation and glomerulonephritis characterised by mixed nephritic/nephrotic syndrome...
