PURPOSE OF REVIEW: The purpose of this review was to summarize recent progress in the field of transcatheter aortic valve replacement (TAVR), discuss expansion of indications, and identify areas of future clinical applications. RECENT FINDINGS: Favorable clinical outcomes as well as continued refinement of transcatheter heart valve technology have prompted the continuous expansion of indications for TAVR. The results of randomized clinical trials comparing the safety and efficacy of TAVR relative to conventional surgical aortic valve replacement (SAVR) in lower- than high-risk patients have recently been published, and trials among lower-risk categories are ongoing...

Quadruple-valve repair or replacement is associated with significant morbidity and mortality because the clinical situation of severe disease of all 4 valves implies incipient myocardial damage. We report a case of redo quadruple-valve repair in a patient with rheumatic heart disease who had undergone the Ross procedure 14 years earlier. He presented with heart failure. Cardiac evaluation revealed severe disease of all 4 valves, necessitating surgery. Because he was in advanced heart failure and all 4 valves were suitable for repair, a quadruple-valve repair was performed...

Modeling different treatment options before a procedure is performed is a promising approach for surgical decision making and patient care in heart valve disease. This study investigated the hemodynamic impact of different prostheses through patient-specific MRI-based CFD simulations. Ten time-resolved MRI data sets with and without velocity encoding were obtained to reconstruct the aorta and set hemodynamic boundary conditions for simulations. Aortic hemodynamics after virtual valve replacement with a biological and mechanical valve prosthesis were investigated...

BACKGROUND: Individuals with repaired tetralogy of Fallot develop pulmonary regurgitation that may cause symptoms (dyspnea, chest pain, palpitations, fatigue, presyncope, and syncope), impair functional capacity, and may affect health-related quality of life. Surgical pulmonary valve replacement is the gold standard of treatment although transcatheter pulmonary valve replacement is becoming more common. Patients want to know whether less invasive options are as good. AIMS: This analysis aimed to examine the differences in surgical versus transcatheter pulmonary valve replacement effects in terms of physiological/biological variables, symptoms, functional status and health-related quality of life...

Tricuspid valve regurgitation (TVR) in the orthotopic heart transplant (OHT) recipient is quite common and has varied clinical sequelae. In its severest forms, it can lead to right-sided failure symptoms indistinguishable from that seen in native heart TVR disease. While certain implantation techniques are widely recognized to reduce the risk of TVR in the cardiac allograft, concomitant tricuspid annuloplasty, while having advocates, is not currently accepted as a routinely established adjunct. Decisions to surgically correct TVR in the OHT recipient must be made carefully, as certain clinical scenarios have high risk of failure...

Concomitant coronary artery disease (CAD) is highly prevalent among patients with severe aortic stenosis (AS). Historically, surgical aortic valve replacement with coronary artery bypass grafting was the only treatment option for patients with severe AS and significant CAD. The rapid expansion of transcatheter aortic valve replacement has led to significant paradigm shifts in the treatment of severe AS and has raised new questions regarding the optimal management of CAD in these patients. We review the evidence regarding management of concomitant CAD in severe AS patients, specifically focusing on issues surrounding transcatheter aortic valve replacement...

The mitral valve apparatus, both functionally and morphologically is composed of a constellation of individual structures, including the annulus, anterior and posterior leaflets, chordae tendineae, and papillary muscles. Most also include the left ventricular wall and the left atrium which are essential for the valve to function normally. Areas covered: The commonest conditions responsible for mitral valve dysfunction in the Western World are degenerative and functional mitral regurgitation, which are discussed in detail...

INTRODUCTION: Aortic stenosis is one of the most common valvular heart diseases in the ageing population. Patients with symptomatic severe aortic stenosis are at high risk of sudden death. Surgical aortic-valve replacement is the gold standard of treatment but many patients do not receive surgery because of advanced age or co-morbidities. Recently, transcatheter aortic valve implantation has been developed as an option for these patients. This study aimed to assess efficacy and safety of this procedure in the Hong Kong Chinese population...

Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves...

Aortic stenosis (AS) is the most frequently observed valvular heart disease. During the symptomatic stage, the rate of death increases dramatically, so that a precise diagnostic approach is taken to guide therapeutic options. Of patients with severe AS, 30% to 50% present with low-flow/low-gradient AS (LF/LGAS) status. This review focuses on LF/LGAS and the best diagnostic and therapeutic management in either classic LF/LGAS with reduced left ventricular ejection fraction (LVEF) or paradoxical LF/LGAS with preserved LVEF...

Transcatheter aortic valve replacement (TAVR) has become a widely accepted therapeutic option for patients with severe, symptomatic aortic stenosis at intermediate, high, or extreme risk for conventional surgery as determined through a heart team approach. Two valve prostheses are currently available and the Food and Drug Administration (FDA) approved in the United States for TAVR: the self-expandable Medtronic CoreValve (Medtronic, Inc., Minneapolis, MN, USA) and the balloon-expandable Edwards Sapien Valve (Edwards Lifesciences, Irvine CA, USA)...

Transcatheter aortic valve implantation (TAVI) is recommended for patients who are inoperable or at high risk for surgical aortic valve replacement (SAVR). Corticosteroid therapy is considered to be a risk factor for SAVR, but there is a paucity of information about TAVI in patients taking corticosteroids. The aim of this study is to elucidate the outcome of TAVI in patients on chronic corticosteroid therapy, compared with SAVR. We retrospectively analyzed patients on corticosteroid therapy who underwent TAVI (n = 21) or SAVR (n = 30) for severe aortic stenosis in Sakakibara Heart Institute...

Cardiac myxomas are the most common type of primary cardiac tumors. They mainly affect the interatrial septum and exceptionally the heart valves. Surgical excision remains the only therapeutic alternative. We here report the case of a 69-year old patient with no significant pathological history suffering from NYHA class II-III dyspnea associated with lipothymia. Transthoracic echocardiography showed a tight calcified aortic narrowing with aortic valve gradient of 58 mmHg. A sessile mass of 15mm diameter inserted into the posterolateral leaflet, without stenosis or mitral regurgitation evoking an atypical localization of myxomaor or fibroelastoma was detected at the level of the mitral valve...

BACKGROUND: Aortic valve disease is a common condition that is easily treatable with cardiac surgery. This is conventionally performed by opening the sternum longitudinally down the centre ("median sternotomy") and replacing the valve under cardiopulmonary bypass. Median sternotomy is generally well tolerated, but as less invasive options have become available, the efficacy of limited incisions has been called into question. In particular, the effects of reducing the visibility and surgical access has raised safety concerns with regards to the placement of cannulae, venting of the heart, epicardial wire placement, and de-airing of the heart at the end of the procedure...

INTRODUCTION: Rheumatic mitral stenosis is the most common Valvular Heart Disease encountered during pregnancy. Balloon Mitral Valvuloplasty (BMV) is one of the treatment option available if the symptoms are refractory to the medical management and the valve anatomy is suitable for balloon dilatation. BMV with Inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique using Joseph Mitral Valvuloplasty (JOMIVA) balloon catheter which is being followed in certain centres...
