BACKGROUND: The Inoue balloon technique is the standard technique for mitral valve balloon commissurotomy at this stage. However, the hardware for this technique is expensive and may not always be available in resource-limited settings. OBJECTIVE: This article reports our experience with percutaneous transmitral balloon commissurotomy using a single balloon (Nucleus) with arteriovenous loop stabilisation. METHOD: Eleven young patients, aged 12-26 years and weighing 23-48 kg, underwent transmitral balloon commissurotomy using the described technique at our centre from April to May 2014...

Intermittent dysfunction of mechanical mitral valve prosthesis is an uncommon condition. It carries serious clinical implications if unrecognized. Here, we present a case of a 28-year-old female with a history of rheumatic multivalvular disease, for which she had undergone double valve replacement and tricuspid annuloplasty. Six months later, she presented with heart failure. Clinical examination revealed intermittent loss of closing clicks followed by a pansystolic murmur at the apex, suggestive of mitral prosthetic valve dysfunction...

AIM: To report our initial experience with lens-sparing vitrectomy for stage 4 retinopathy of prematurity using the 27-gauge (G) system. METHODS: This retrospective case series involved nine eyes of five babies with active stage 4 ROP, who underwent 27-G lens-sparing vitrectomy. Surgery was done using 27-G valved cannulas and sclerotomies were made 1.5 mm from the limbus. Bilateral sequential vitrectomy was done in eight eyes. RESULTS: At one-year follow-up, anatomical outcome was favourable in all nine (100%) eyes...

Calcifications occur during the development of healthy bone, and at the onset of calcific aortic-valve disease (CAVD) and many other pathologies. Although the mechanisms regulating early calcium deposition are not fully understood, they may provide targets for new treatments and for early interventions. Here, we show that two-photon excited fluorescence (TPEF) can provide quantitative and sensitive readouts of calcific nodule formation, in particular in the context of CAVD. Specifically, by means of the decomposition of TPEF spectral images from excised human CAVD valves and from rat bone prior to and following demineralization, as well as from calcific nodules formed within engineered gels, we identified an endogenous fluorophore that correlates with the level of mineralization in the samples...

Suttonella indologenes is a Gram-negative, aerobic coccobacillus of Cardiobacteriaceae family and its natural habitat is the mucous membranes of the upper respiratory system. The literature includes limited number of case reports concerning fatal endocarditis due to infection in the prosthetic heart valves caused by the aforementioned microorganism. However, there is no information on extracardiac involvement due to this microorganism. Here, we present a peritonitis case caused by Suttonella indologenes in a patient receiving continuous ambulatory peritoneal dialysis...

OBJECTIVE: Our institution uses a valved polytetrafluoroethylene conduit as an alternative to homografts. The objective of this study was to investigate the performance of bicuspid valved polytetrafluoroethylene conduits used for right ventricular outflow tract reconstruction in children aged less than 2 years and to evaluate risk factors for earlier conduit explant. METHODS: We performed an Institutional Review Board-approved retrospective chart review of all patients aged less than 2 years who underwent surgical right ventricular outflow tract reconstruction with a bicuspid valved polytetrafluoroethylene conduit or homograft conduit from July 2004 to December 2014...

BACKGROUND: The aim of this study was to examine the association between abnormal morphology of the proximal aorta and aortic stenosis (AS) progression rate. The main hypothesis was that morphologic changes of the proximal aorta, such as effacement of the sinotubular junction (STJ), result in increased biomechanical stresses and contribute to calcification and progression of AS. METHODS: Between 2010 and 2012, 426 patients with mild to moderate AS were included in this study...

There is controversy about handling functional mitral regurgitation in patients undergoing aortic valve or proximal aortic operations. We describe a transaortic Alfieri edge-to-edge repair for functional mitral regurgitation that reduces operative excessive invasion and prolonged cardiopulmonary bypass time. Between May 2013 and December 2016, 10 patients underwent transaortic Alfieri edge-to-edge mitral repair. There were no operative deaths. The severity of mitral regurgitation immediately after the operation by transesophageal echocardiography was none or trivial in all patients...

Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction...

Sutureless aortic valves are increasingly used for aortic valve replacement (AVR) with excellent outcomes. Implantation requires device expansion in a subannular position within the native aortic root. We report a patient with severe aortic stenosis who received a Perceval sutureless AVR (LivaNova, London, United Kingdom), resulting in a competent prosthesis with an absence of paravalvular leak and aortic regurgitation. However, this implantation resulted in the exacerbation of mitral regurgitation. The sutureless valve required explantation, and a traditional sutured valve was subsequently implanted, which returned the mitral regurgitation to baseline...

PURPOSE: Rapid deployment/sutureless aortic valve replacement is aimed at minimizing the invasiveness of surgical aortic valve replacement. We describe the implantation techniques of a new rapid deployment aortic valve, focusing on its unique and challenging features. DESCRIPTION: The EDWARDS INTUITY Elite aortic valve (Edwards Lifesciences, Irvine, CA) represents a hybrid between the surgical PERIMOUNT Magna Ease (Edwards Lifesciences) pericardial valve, but with advanced features of the percutaneous SAPIEN valve system (Edwards Lifesciences)...

OBJECTIVES: Investigate the effects of left and right ventricular function and severity of pulmonary valve regurgitation, quantified by cardiac magnetic resonance (CMR), on exercise tolerance in adult patients who underwent ToF repair at a young age. METHODS: This is a retrospective cohort study of 52 patients after ToF surgery and 33 age- and sex-matched healthy volunteers. CMR and cardiopulmonary exercise testing (CPET) were performed on all patients; CPET was performed on control subjects...

OBJECTIVE: To study the echocardiographic features of criss-cross heart (CCH), a congenital cardiac anomaly characterized by crossed ventricular inflow streams, in Indian patients. METHODS: In this retrospective observational study, all pediatric echocardiograms performed in a single tertiary care institution in South India over a three-year period were scrutinized for a diagnosis of CCH. Demographic, clinical and echocardiographic data were collected from patients' medical records and echocardiographic database...

PURPOSE: To report a case of rupture of the descending aorta after aortic migration during transcatheter aortic valve replacement (TAVR). CASE REPORT: An 85 year-old man with a severe and symptomatic aortic stenosis underwent elective TAVR, which complicated with embolization into the ascending aorta. While repositioning into the descending aorta the procedure complicated with aortic rupture. The patient required urgent thoracic intra-valve stent graft implantation (TEVAR)...

OBJECTIVES: The purpose of this study was to investigate the association between right ventricular dysfunction (RVD) and cardiovascular death after transcatheter aortic valve replacement (TAVR). BACKGROUND: There is conflicting evidence on the effect of RVD on clinical outcomes after TAVR. METHODS: A total of 1,116 TAVR patients (age 82 ± 6 years; 51% female) who were consecutively enrolled into a prospective registry underwent detailed pre-operative assessment of right ventricular (RV) function and were dichotomized into 2 groups for the purposes of the present retrospective analysis...
