Because of its favourable haemodynamic characteristics and easy implantability, Mitroflow aortic valve bioprosthesis has been the valve of choice for many surgeons in patients with small aortic annulus. Disappointingly, early structural valve deterioration and high transvalvular gradients have been reported mostly in older patients with small prostheses. Reimplanting a new stented prosthesis sutured in a narrow and damaged annulus is technically challenging and demanding mainly in high-risk patients. Valve-in-valve transcatheter aortic valve implantation has been proposed as a viable option; however, it presents significant limitations because of residual high transprosthetic pressure gradients and risk of coronary occlusion...

In recent years, transcatheter aortic valve implantation (TAVI) has been considered a novel option for the management of surgically high-risk patients requiring aortic valve replacement. Presently described is a case of acute coronary syndrome (ACS) managed with a challenging primary percutaneous coronary intervention (PCI) shortly after a valve-in-valve TAVI intervention. This case highlights 2 important issues: PCI may be an option for the management of coronary heart disease in patients after TAVI even in the setting of demanding features associated with coronary osteal engagement, and secondly, TAVI may serve as a potential risk factor for future coronary ischemic syndromes, largely due to its potential adverse effects on coronary flow dynamics, etc...

OBJECTIVE: Remodeling or reimplantation are established operative techniques of aortic valve-sparing root replacement. Long-term follow-up is necessary comparing tricuspid and bicuspid aortic valves. METHODS: A total of 315 patients (tricuspid, n = 225, bicuspid, n = 89, quadricuspid, n = 1; remodeling, n = 101, reimplantation, n = 214) were evaluated. Mean follow-up was 10.1 ± 5.6 and 6.4 ± 4.2 years for the remodeling and reimplantation group, respectively...

The objective of our study was to compare the cellular and extracellular matrix (ECM) structure and the biomechanical properties of human pericardium (HP) with the normal human aortic heart valve (NAV). HP tissues (from 12 patients) and NAV samples (from 5 patients) were harvested during heart surgery. The main cells in HP were pericardial interstitial cells (PICs), which are fibroblast-like cells of mesenchymal origin similar to the valvular interstitial cells (VICs) in NAV tissue. The extracellular matrix (ECM) of HP had a statistically significantly (p ≤ 0...

BACKGROUND: Current retrospective evidence suggests similar clinical and superior hemodynamic outcomes of the Sorin Freedom Solo stentless aortic valve (SFS) (LivaNova PLC, London, UK) compared to the Carpentier Edwards Perimount stented aortic valve (CEP) (Edwards Lifesciences Inc., Irvine, California, USA). To date, no reports exist describing case-matched long-term outcomes and analysis for treatment of native valve endocarditis (NVE). METHODS: From 2004 through 2014, 77 consecutive patients (study group, 59...

Quadricuspid aortic valve (QAV) is a rare congenital anomaly frequently associated with other anomalies particularly coronary anomalies. It may be detected on transthoracic or transesophageal echocardiography. We present here a case report of a 27-year-old male patient with a QAV, the valve being regurgitant and requiring aortic valve replacement. It has been reported as isolated case reports in the literature and various theories exist to the development of QAV. The diagnosis requires a high degree of suspicion and a detailed assessment, and if asymptomatic, then patients need to be carefully followed up for the development of aortic regurgitation...

Bicuspid aortic valve is the most common congenital cardiac defect in adults, and symptom typically develops in adulthood. In the majority of cases, bicuspid aortic valve disease progress with ages and surgical aortic valve replacement is performed with excellent operative outcomes. However, with the relatively slow progression of disease, surgical aortic valve replacement is required in elderly patients but the surgical risk often deemed extremely high due to old age and multiple comorbidities. Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for intermediate- and high-risk patients with symptomatic severe aortic valve stenosis (AS)...

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)...

The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (ContegraR) graft (31 patients)...

An 88-year-old woman with a prior history of aortic stenosis and history of valvuloplasty presented with worsening symptoms of heart failure and dizziness. She underwent successful transcatheter aortic valve replacement (TAVR) without complications. Follow-up echocardiograms revealed a small fistula connecting aorta to the right ventricle. The patient was initially asymptomatic but 3 months later developed overload of the right ventricle and heart failure and chose to continue medical therapy. She died of progressive heart failure at 9 months from onset of fistula...

OBJECTIVES: The aim of this study was to provide predictive data on the performance of the Freestyle stentless bioprosthesis that can be used to support and improve the shared decision-making process of prosthetic valve choice for aortic valve replacement. METHODS: Between 1993 and 2014, 604 patients received the Freestyle stentless bioprosthesis (143 subcoronary, 58 root inclusion and 403 full-root replacement). Perioperative data were collected retrospectively, and follow-up data were collected prospectively from 2015...

OBJECTIVES: Right ventricular (RV) function is impaired after cardiac surgery, possibly because of the opening of the pericardium. In minimally invasive aortic valve replacement, the pericardium is only partially incised. METHODS: A randomized trial compared RV function after ministernotomy versus full sternotomy in 40 adults undergoing aortic valve replacement at the Karolinska University Hospital. Primary outcomes were tricuspid annular plane systolic excursion, RV pulsed-wave tissue Doppler velocity, RV fractional area change and basal and mid-RV transversal diameters on postoperative Days 4 and 40...

Objectives: Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. Methods: The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach...

BACKGROUND: Low cardiac output syndrome is a main cause of death after cardiac surgery. We sought to assess the impact of glucose-insulin-potassium (GIK) to enhance myocardial protection in moderate- to high-risk patients undergoing on-pump heart surgery. METHODS: A randomized controlled trial was performed in adult patients (Bernstein-Parsonnet score >7) scheduled for elective aortic valve replacement and/or coronary artery bypass surgery. Patients were randomized to GIK (20 IU of insulin, 10 mEq of potassium chloride in 50 mL of glucose 40%) or saline infusion given over 60 minutes on anesthetic induction...
