Percutaneous MitraClip placement for treatment of severe mitral regurgitation in high surgical risk patients is a commonly performed procedure and requires a transseptal puncture to reach the left atrium. The resulting iatrogenic atrial septal defect (iASD) is not routinely closed, yet the haemodynamic and functional consequences of a persisting defect are not fully understood. Despite positive effects such as acute left atrial pressure relief, persisting iASDs are associated with negative consequences, namely significant bidirectional shunting and subsequent worse clinical outcome...

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...

BACKGROUND: MitraClip (MC) is an alternative treatment for mitral regurgitation (MR). Although residual MR is common after MC, little was known about the impact of residual MR after MC. METHODS: We examined 255 consecutive patients who underwent MC. The primary endpoint was the composite endpoint including all-cause death, left ventricular (LV) assist device, and mitral valve surgery. RESULTS: Procedure failure defined as unsuccessful MC implantation (n=6) and residual MR ≥3+ (n=19) was associated with worse outcomes including the primary endpoint and all-cause death than those with acute procedure success (APS) defined as residual MR 2+ (n=125) or 1+ (n=105)...

The case fatality rate of infective endocarditis (IE) is high and is associated with varying causes. Among them, acute myocardial infarction due to an embolism in a coronary artery is rare; the incidence of this complication in the setting of IE is reported to be up to 1.5%. We report a case of sudden death in a 22-year-old woman diagnosed with systemic lupus erythematosus who was referred to the Cardiology Center for the treatment of mitral valve incompetence due to IE. She was hemodynamically stable with antibiotic therapy and vasoactive drugs, despite severe mitral valve regurgitation...

OBJECTIVE: Mitral valve regurgitation (MR) is the second most common heart valve disease in Europe. Without intervention, prognosis of severe symptomatic MR is poor. Percutaneous edge-to-edge mitral valve repair with MitraClip is a promising mitral regurgitation treatment technique in select, high-surgical-risk patients. The present objective was to describe the experience of a single center with MitraClip use in a high-risk series in Turkey. METHODS: Between May 2013 and September 2014, 28 high-surgical-risk patients with MR of at least grade 3+ and mean EuroSCORE of 26% underwent MitraClip implantation at our institution...

BACKGROUND: Percutaneous mitral valve repair (PMVR) is an alternative treatment in patients with significant mitral regurgitation (MR) who are denied surgery. Although in surgical patients, outcomes have been related both to acute hemodynamic favorable results and to positive cardiac remodeling in the midterm, in the case of PMVR the effect on cardiac chamber remodeling has never been extensively studied. The aims of this study were (1) to evaluate the short- and mid-term remodeling induced by PMVR on cardiac chamber volume using two- and three-dimensional (3D) transthoracic echocardiographic (TTE) imaging and (2) to assess changes in left ventricular (LV) shape on the basis of 3D TTE data...

Ventricular septal rupture (VSR) occurs in approximately 1% of the patients who experience an acute myocardial infarction. The operative mortality of VSR repair decreases if surgery can be delayed until the infarct has healed and tissue strength improved. Because of heart failure or impending cardiogenic shock, surgical treatment can often not be delayed. We present a case in which a delayed repair of a VSR was possible. The patient was initially stabilized with an intra-aortic balloon pump. She was discharged and readmitted 5 weeks later for definitive repair...

Papillary muscle rupture is a rare, life-threatening post myocardial infarction mechanical complication. Without surgical intervention, prognosis is very poor. Clinicians need to recognize this complication early, as prompt therapy is crucial. We present a case of inferior ST elevation myocardial infarction complicated by posteromedial papillary muscle rupture resulting in severe acute mitral regurgitation (flail anterior mitral leaflet), acute pulmonary edema and cardiogenic shock. In our patient, a new mitral regurgitation murmur suggested this mechanical complication...

Cardiovascular manifestations of tertiary syphilis infections are uncommon, but represent an important cause of mortality and morbidity. Syphilitic aortitis is characterized by aortic regurgitation, dilatation of ascending aorta and ostial coronary artery lesions. We report a case of 36 years old man admitted to our hospital for acute anterior ST segment elevation myocardial infarction complicated with cardiogenic shock (hypotension 75/50 mmHg). Transthoracic echocardiography revealed a dilated left ventricle with severe systolic dysfunction (ejection fraction = 25%), severe mitral regurgitation, moderate aortic regurgitation and mildly dilated ascending aorta...

Acute mitral regurgitation (acute MR) is a rare cause of acute respiratory distress, which can present diagnostic challenges. We present the case of a 57 year old man who developed acute shortness of breath subsequently associated with fever, raised white cells and elevated CRP. Chest x-ray revealed unilateral shadowing and he was treated for pneumonia, despite the finding of severe mitral regurgitation on echo. Failure to respond to antibiotic treatment following 3 weeks on ITU led to the consideration of acute MR as the cause of his symptoms and he responded well to diuretics...

Severe mitral regurgitation due to prolapse of the valve demands early surgical intervention. Recently artificial chord implantation is the prefered solution, which requires cardioplegia and application of cardiopulmonary bypass using the left atrial approach. Transoesophageal echocardiography guided transapical neochord implantation is an emerging new technique for the treatment of mitral regurgitation. It enables the operation through left minithoracotomy on beating heart using a special instrument introduced into the left ventricle...

We report the case of a 61-year-old woman with acute decompensated heart failure secondary to acute traumatic mitral regurgitation, resulting from polymethylmethacrylate cement found in the left ventricle less than 24 hours after fluoroscopic percutaneous vertebroplasty. The patient had a history of ovarian cancer and had undergone treatment for symptomatic osteoporotic compression fractures of the vertebrae (T11, L1, and L3). The patient underwent a successful emergency open-heart operation, mitral valve replacement, closure of an atrial septal defect, and video-assisted removal of the cement foreign body from the left ventricle...

BACKGROUND AND AIMS: One option for interventional treatment of secondary mitral regurgitation is the placement of an indirect mitral annuloplasty device (Carillon Mitral Contour System) cinching the mitral annulus to facilitate coaptation of the mitral leaflets. The aim of this study is to evaluate the implantation success and hemodynamic results. METHODS AND RESULTS: Seventeen consecutive patients (11 females, 6 males) suffering from moderate to severe secondary mitral regurgitation (40% ischemic, 59% non-ischemic) received a Carillon Mitral Contour System device, which was evaluated prospectively in a single-center setting...

OBJECTIVE: The optimal treatment strategy in patients with coronary artery disease and ischemic mitral regurgitation (IMR) remains controversial. A staged approach of percutaneous coronary intervention (PCI) followed by minimally invasive valve surgery, rather than combined median sternotomy coronary artery bypass and valve surgery, may be a viable alternative. METHODS: We retrospectively evaluated 31 consecutive patients with coronary artery disease and severe IMR who underwent a staged procedure at our institution between February 2009 and April 2014...

INTRODUCTION: Takotsubo cardiomyopathy (TCM) can be complicated by left ventricular outflow tract (LVOT) obstruction and severe acute mitral regurgitation (MR), leading to hemodynamic instability in an otherwise benign disorder. Despite the severity of these complications, there is a paucity of literature on the matter. Because up to 20-25% of TCM patients develop LVOT obstruction and/or MR, it is important to recognize the clinical manifestations of these complications and to adhere to specific management in order to reduce patient morbidity and mortality...
