Amongst patients with mitral stenosis (MS), the most common complication is AF.Our study aimed at evaluating the effect of AF cardioversion after Percutaneous Mitral Balloon Valvuloplasty (PMBV) on echocardiographic atrial functions. The study included 34 patients with MS and AF, presenting to Ain-shams University hospitals, who underwent successful PMBV then randomized into 2 different groups according to AF management strategy. Group-I patients (n=16) received DC cardioversion after amiodarone infusion (within 24 hours post-PMBV) in addition to anticoagulation...

Cor triatriatum sinister (CTS) is a rare congenital abnormality. Clinical presentation of patients with CTS mainly depends on the anatomic features of membrane and may vary from mild or moderate symptoms mimicking mitral stenosis to more severe and complicated cardioembolic stroke or a new onset heart failure. We herein have reported on a young male who presented with the signs and symptoms of mitral stenosis and was diagnosed as CTS with gradient on the orifice of the membrane after transthrocacic echocardiography...

BACKGROUND AND OBJECTIVES: The most common injury to the heart valve with rheumatic involvement is mitral stenosis, which is the reason for a big number of cardiac operations in Brazil. Commissurotomy is the traditional technique that is still widely used for this condition, although late postoperative restenosis is concerning. This study's purpose was to compare the histological findings of porcine cusp mitral valves treated in vitro with commissurotomy with a scalpel blade to those treated with high-power laser (HPL) cutting, using appropriate staining techniques...

We have modified the mitral repair technique in infants and small children by using autologous pericardial strips to treat mitral regurgitation resulting from a dilated mitral annulus. Our results demonstrate that this technique maintains stability and flexibility of the mitral annulus and decreases the risk of mitral stenosis.

Lutembacher syndrome is defined as a combination of congenital Atrial Septal Defect (ASD) with an acquired Mitral Stenosis (MS). There are various challenges involved in the percutaneous management of Lutembacher syndrome. Here, we present a case that had a very small Left Atrium (LA) and Left Ventricle (LV) cavities with an anteriorly placed ASD. We used Transoesophageal echocardiography (TEE) to take a separate interatrial septal puncture and complete the Balloon Mitral Valvotomy (BMV) procedure. Finally both the defects in interatrial septum were closed with the help of a large device...

PURPOSE OF REVIEW: This review summarizes the evidence describing functional mitral stenosis (MS) following surgical mitral valve repair. RECENT FINDINGS: Functional MS is an evolving concept and has been implicated in the repair of functional and organic mitral regurgitation. Following repair of functional mitral regurgitation, an elevation in peak transmitral gradient and pulmonary artery pressure has been observed under physiologic stress. These changes have been associated with worse functional status early after restrictive annuloplasty...

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)...

Left atrial thrombus after acute pancreatitis (AP) is a rare clinical statement. Because of induction of systemic prothrombotic process by AP; some patients with underlying risk factors may develop an intra-cardiac thrombus. We present a 53years-old-woman with moderate mitral stenosis and atrial fibrillation. However the patient was under warfarin treatment, she developed a big left atrial big thrombus which was originated from left atrial appendage after she was suffered from AP.

REVIEW
Takahiro Shiota
Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures...

Andrew C T Ha, Atul Verma, Subodh Verma
PURPOSE OF REVIEW: The majority of evidence on the safety and efficacy of oral anticoagulation for stroke prevention amongst patients with atrial fibrillation is derived from those without significant valvular heart disease. This article will review current knowledge, areas of uncertainty and controversy, and ongoing research on oral anticoagulation for stroke prevention amongst patients with valvular heart disease. RECENT FINDINGS: The rates of stroke, systemic embolism, and major bleeding were similar for patients with and without significant native valvular disease when treated with direct oral anticoagulants (DOACs) or vitamin K antagonists...

BACKGROUND: Auckland City Hospital (ACH) established a Heart Murmur Clinic (HMC) with the aim of providing prompt assessment of patients with asymptomatic systolic murmurs. This may lead to early intervention and improved outcomes if significant structural heart disease is detected and reassurance if no significant findings found. Similar clinics for children have proven beneficial; the benefit of a HMC in an adult population has been difficult to determine. OBJECTIVES: To review the clinical demographics and echocardiographic information of patients presenting to our HMC and to assess what proportion had significant structural heart disease and determine the common structural abnormalities in this population...
