Prolonged left atrial electromechanical conduction time is related with atrial electrical remodeling, and is predictive of the development of atrial fibrillation. The aim of our study was to examine whether left atrial electromechanical conduction time (EMT) and left atrial strain as measured by speckle tracking echocardiography (STE) are predictors for the development of atrial fibrillation (AF) in patients with mitral stenosis (MS) at 5-year follow-up. A total of 81 patients (61% females; mean age 38.1 ± 12...

OBJECTIVES: According to recent guidelines, mitral valve (MV) repair is preferable to replacement. However, replacement is sometimes inevitable. Aims of the study were to identify variables that predict the risk of an unsuccessful MV repair and to evaluate a score that could help in planning MV surgical procedures. METHODS: Clinical data of all consecutive adult mitral valve surgical procedures, performed during a 50-month period, were extracted from our clinical registry, and combined with echocardiographic variables...

PURPOSE: The aim of this study was to evaluate the proportion of suspected heart failure patients with significant valvular heart disease. Early diagnosis of valve disease is essential as delay can limit treatment and negatively affect prognosis for undiagnosed patients. The prevalence of unsuspected valve disease in the community is uncertain. PARTICIPANTS: We prospectively evaluated 79 043 patients, between 2001 and 2011, who were referred to a community open access echocardiography service for suspected heart failure...

Direct oral anticoagulants (DOACs) are indicated for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF), which, according to the American College of Cardiology/American Heart Association/Heart Rhythm Society atrial fibrillation (AF) guidelines, excludes patients with rheumatic mitral stenosis, a mechanical or bioprosthetic heart valve, or mitral valve repair. However, the data regarding use of DOACs in AF patients with other types of valvular heart disease (VHD) are unclear. We aimed to summarize and evaluate the literature regarding the safety and efficacy of DOAC use in NVAF patients with other types of VHD...

Aortic stenosis is the most frequent and mitral stenosis is the least frequent native single-sided valve disease in Europe. Patients with the combination of severe symptomatic degenerative aortic and mitral stenosis are very rare. Guidelines for the treatment of heart valve diseases are clear for single-valve situations. However, there is no common agreement or recommendation for the best treatment strategy in patients with multiple valve disease and severe concomitant comorbidities. A 76-year-old female patient with the combination of severe degenerative symptomatic aortic and mitral stenosis and several comorbidities including severe obesity, who was found unsuitable surgical candidate by the heart team and unsuitable for two-time general anesthesia in the case of two-step single-valve percutaneous approach by anesthesiologists, underwent successful percutaneous dual-valve single-intervention (transcatheter aortic valve implantation and percutaneous mitral balloon commissurotomy)...

Objective: Right heart function is a major determinant of clinical outcome in patients with elevated pulmonary artery pressure due to pulmonary venous hypertension (PVH) and pulmonary arterial hypertension (PAH). Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase. In our study, we aimed to evaluate if different type of pulmonary hypertension (PH) cause the same effect on right heart functions and serum asymmetric dimethylarginine (ADMA) levels in female patients...

In this prospective observational study, conducted at an academic medical center, we evaluated the feasibility of performing a basic transesophageal echocardiography (TEE) examination using endoscopic ultrasound (EUS) technology to determine what cardiac structures could be assessed. This may be potentially beneficial during hemodynamic emergencies in the endoscopy suite resulting from hypovolemia, depressed ventricular function, aortic dissection, pericardial effusions, or aortic stenosis. Of the 20 patients enrolled, 18 underwent EUS with a linear echoendoscope for standard clinical indications followed by a cardiac assessment performed under the guidance of a TEE-certified cardiac anesthesiologist...

Non-vitamin K oral anticoagulants (NOACs) are currently recommended for patients with nonvalvular atrial fibrillation since the publication of the 4 major pivotal trials evaluating the efficacy and safety of factor IIa and factor Xa inhibitors. The definition of nonvalvular atrial fibrillation is unclear, varying from one trial to another and even between North American and European guidelines, which is a source of uncertainties in clinical practice. However, many patients with atrial fibrillation present signs of valvular involvement, and clarification of this term is needed to not deny NOACs to patients based on the wrong perception that they may have valvular atrial fibrillation...

OBJECTIVES: In this review, we will discuss aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis. We will review the etiology, anatomy, pathophysiology, presentation, and treatment of aortic and mitral valve disease. Age and lesion specific treatments are outlined based on the severity of valve disease with an aim at long-term preservation of left ventricular function. DATA SOURCE: MEDLINE and PubMed. CONCLUSIONS: Mitral and aortic valve disease leads to unique hemodynamic burdens that can impact left ventricular function, quality of life, and longevity...

The choice of prosthesis type in patients with valvular heart disease should always be individualised. The treating heart team must weigh the concerns surrounding durability of bioprosthetic valves compared with mechanical valves and the need for lifelong anticoagulation required with mechanical valves. In general, guidelines recommend that patients under the age of 60 would benefit from a mechanical valve, and those over 70 would benefit from a bioprosthetic valve. We would argue, in this context, that the most appropriate choice for this patient would be undertaking a mitral valve replacement with a mechanical prosthesis...

The dilemma of the patient with both AS and LVOTO is now commonly encountered in clinical practice; indeed, physicians must be aware of the complex interaction and coexistent nature of both diseases, especially as both HOCM and TAVR have increased in awareness and prevalence. Importantly, the clinician must be aware of the complex interplay hemodynamically, with the two diseases confusing the TTE imaging and potentially affecting each other anatomically and clinically. There is no set guideline on how to approach this from a surgical or percutaneous approach, but we have outlined a set of recommendations which should serve the clinician and patient well...

BACKGROUND: Current guidelines define severe aortic valve stenosis (AS) as an aortic valve area (AVA) ≤1.0 cm by the continuity equation and mean gradient (ΔPm) ≥ 40 mm Hg. However, these measurements can be discordant when classifying AS severity. Approximately one-third of patients with normal ejection fraction and severe AS by AVA have nonsevere AS by ΔPm when measured by preoperative transthoracic echocardiography (TTE). Given the use of positive pressure ventilation and general anesthesia in the pre-cardiopulmonary bypass (pre-CPB) period, we hypothesized that discordance between ΔPm and AVA during pre-CPB transesophageal echocardiography (TEE) would be higher than previously reported by TTE...

Epidemiology of acquired valvular heart diseases has changed significantly over last decades. Degenerative aortic valve stenosis is the most common acquired valvular disease with high prevalence in elderly population. Another common disorder is ischemic mitral regurgitation secondary to myocardial infarction. Both above-mentioned heart disorders are not typical for women in reproductive age. Rheumatic heart valve disease has become infrequent in Polish population. Mitral stenosis, the most prevalent of rheumatic valvular disorders, affects 5% of pregnant women with heart disease and rheumatic aortic stenosis is responsible for 0...

Atrial fibrillation (AF) confers a substantial risk of stroke. Recent trials comparing vitamin K antagonists (VKAs) with non-vitamin K antagonist oral anticoagulants (NOACs) in AF were performed among patients with so-called "non-valvular" AF. The distinction between "valvular" and "non-valvular" AF remains a matter of debate. Currently, "valvular AF" refers to patients with mitral stenosis or artificial heart valves (and valve repair in North American guidelines only), and should be treated with VKAs. Valvular heart diseases, such as mitral regurgitation, aortic stenosis (AS) and aortic insufficiency, do not result in conditions of low flow in the left atrium, and do not apparently increase the risk of thromboembolism brought by AF...

Lesions of the heart valves are the commonest acquired cardiac abnormalities seen in pediatric age group. Aortic regurgitation (AR) results from abnormality of the valve leaflets or of the aortic root. Mitral valve lesion may be associated in patients with rheumatic heart disease (RHD). Left ventricle dilates and may develop dysfunction in advanced states. Coronary perfusion also tends to suffer in severe AR. The symptoms develop later and include dyspnea and palpitations. An early diastolic, high pitched murmur, best heard at base of the heart is the hallmark of AR...

OBJECTIVES: Mitral regurgitation (MR) is a common entity in patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR), but its influence on outcomes remains controversial. The purpose of this meta-analysis was to assess the clinical impact of and changes in significant (moderate-severe) MR in patients undergoing TAVR, overall and according to valve design (self-expandable (SEV) vs balloon-expandable (BEV)). METHODS: All national registries and randomised trials were pooled using meta-analytical guidelines to establish the impact of moderate-severe MR on mortality after TAVR...

AIMS: The CHA2DS2VASc score is a clinical risk stratification tool which estimates the risk of stroke and thromboembolism in non-valvular atrial fibrillation (AF). We aimed to establish the value of this score for risk evaluation in patients with non-valvular AF and valvular heart disease. METHODS AND RESULTS: Among 8053 patients with non-valvular AF (ESC guidelines definition), patients were categorized into Group 1 (no valve disease, n = 6851; 85%) and Group 2 (valve disease with neither rheumatic mitral stenosis nor valve prothesis, n = 1202; 15%)...

Mitral valve disease (MVD) related to mitral valve prolapse (MVP), coronary artery disease (CAD), and calcific mitral stenosis, is increasing in prevalence across the USA and Europe in the context of a longer life expectancy and aging population. In developing countries, rheumatic heart disease remains a major cause of MVD. Echocardiography represents the primary diagnostic modality for assessment of the mitral valve (MV). With the implementation of three-dimensional imaging, echocardiography has become an indispensable tool to evaluate the morphology, geometry, and function of the MV apparatus in the pre-operative setting...
