Mitral valve percutaneous intervention

Michaela M Hell, Stephan Achenbach
Due to its high temporal and isotropic spatial resolution, CT has become firmly established for pre-procedural imaging in the context of structural heart disease interventions. CT allows to very exactly measure dimensions of the target structure, CT can provide information regarding the access route and, as a very valuable addition, volumetric CT data sets can be used to identify fluoroscopic projection angulations to optimally visualize the target structure and place devices. This review provides an overview of current methods and applications of pre-interventional CT to support adult cardiac interventions including transcatheter aortic valve implantation, percutaneous mitral valve intervention, left atrial appendage occlusion and paravalvular leak closure...

Mitral regurgitation is a highly prevalent condition among elderly patients, affecting almost 10% of the general population aged 75 and older. Left untreated, severe mitral regurgitation results in high mortality and frequent hospitalisation for treatment of heart failure. Surgical treatment remains the first-line therapy for symptomatic, severe mitral regurgitation , especially for patients presenting with a primary aetiology. However, a high proportion of patients with mitral regurgitation are turned down for open-heart surgery, mainly due to advanced age, diminished left ventricular function and comorbidities...

The diagnosis of acute mitral regurgitation (MR) is often missed or delayed because the clinical presentation is substantially different from that in patients with chronic MR. Management of acute MR depends on the specific aetiology of valve dysfunction and there is a lack of consensus on the optimal therapeutic approach in many patients. In particular, management of secondary MR due to acute ischaemia is challenging because of unique mechanisms of valve incompetence compared with chronic ischaemic MR. Another clinical challenge is management of acute MR due to transient systolic anterior motion of the mitral valve in the acute phase of Takotsubo cardiomyopathy, which commonly resolves within a few weeks...

PURPOSE: Cognitive impairment and reduced quality of life is a common condition in patients with heart failure (HF). Percutaneous mitral valve repair using (PMVR) MitraClip (MC) has emerged as a promising interventional tool, reducing all-cause mortality and hospitalization as well as increasing cognitive functioning and quality of life. However, the benefit of HF patients with severely depressed cognitive functioning remains unknown. METHODS: We assessed cognitive functioning (figural memory-FGT, executive function-TOL, TMT B), psychosocial functioning (depression-PHQ-9, quality of life-SF36), and clinical parameters (echocardiography, 6-min walk test distance, and cardiac biomarkers) 1 day before (t0) and 6 weeks after (t1) MC intervention in HF patients (n = 40)...

Percutaneous intervention for mitral valve disease has been established as an alternative to open surgical repair in high risk and inoperable candidates. Edge-to-edge leaflet plication with Mitraclip (Abbott, Menlo Park, CA, USA) is indicated for primary and secondary mitral valve diseases. Echocardiography provides a better understanding of mitral valve anatomy and allows us to classify and quantify mitral regurgitation. Transesophageal echocardiography is essential in patient screening, intraprocedural guidance, and post-procedure evaluation for patients undergoing edge-to-edge plication with MitraClip...

The left circumflex (LCX) artery is located close to the mitral valve (MV), making it susceptible to injury during MV surgery. We are reporting our experience in the diagnosis and management of this complication. We retrospectively reviewed our surgical and coronary angiography databases for patients with documented LCX artery injury during MV surgery between January 2000 and December 2016. The complication was associated with MV replacement (9/1313, 0.7%) but not MV repair (0/393, 0.0%). Eight patients (88...

This study was performed to investigate the prevalence and impact on survival of baseline mitral stenosis (MS) in patients who underwent transcatheter aortic valve implantation (TAVI) due to the presence of severe symptomatic aortic stenosis. This retrospective study included 928 consecutive patients with severe, symptomatic aortic stenosis who underwent TAVI in 2 institutions, from January 2012 to August 2016. Mean follow-up was 40.8 ± 13.9 months. Based on the mean mitral gradient (MMG) at baseline, 3 groups were identified: MMG <5 mm Hg (n = 737, 81...

Even cardiac surgery has been accepted as the standard therapy for Lutembacher syndrome, a combination of congenital ostium secundum atrial septal defect (ASD) and acquired mitral valve stenosis (MVS), it also owns many limitations and disadvantages. Therefore, seeking for a less invasive therapy with the same efficacy may be worthwhile. Thanks to the development in technology and experience gaining in cardiovascular intervention, the combination of the two proved effective procedures, including percutaneous MVS treatment using balloon valvuloplasty and percutaneous ASD closure using atrial septal occluders, can be utilized as an attractive alternative therapy for these conditions...

Recent innovations and advancements in 3-dimensional (3D) echocardiography allow for better understanding of anatomic relationships and improve communication with the interventional cardiologist for guidance of catheter-based interventions. The mitral valve lends itself best for imaging with transesophageal echocardiography (TEE). Consequently, the role of 3D TEE in guiding catheter-based mitral interventions has been evolving rapidly. Although several publications have reported on the advantages and role of 3D TEE in guiding one or more of the steps involved in percutaneous mitral valve repair using the MitraClip, none offer a comprehensive and practical user-friendly guide...

Traditional approaches to the characterization of secondary or functional mitral regurgitation (MR) have largely ignored the critical importance of the left ventricle (LV). We propose that patients with secondary MR represent a heterogenous group, which can be usefully subdivided based on understanding that the effective regurgitant orifice area (EROA) is dependent on left ventricular end-diastolic volume (LVEDV). According to the Gorlin hydraulic orifice equation, patients with heart failure, an LV ejection fraction of 30%, an LVEDV of 220 to 250 ml, and a regurgitant fraction of 50% would be expected to have an EROA of ≈0...

Papillary muscle rupture is a rare complication after myocardial infarction and almost all cases occur in the mitral valve papillary muscle. Tricuspid regurgitation development after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare.  In this video tutorial we present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous stenting of the right coronary artery. We performed tricuspid valve repair with reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve...

Surgical management of patients with aortic valve stenosis is declining and Transcatheter aortic valve implantation (TAVI) is becoming the treatment of choice in many patients. The ESC guideline integrated results of randomized controlled trials in patients with intermediate surgical risk for the first time. TAVI showed good and comparable results to the standard surgical approach.Mitral regurgitation (MR) is a complex disease with good surgical results in primary MR and mixed results in secondary MR. Secondary MR is mainly based on left ventricular disease with subsequent dilatation...

Transcatheter interventions for valvular and structural heart diseases are rapidly expanding due to greater operators' experience and development of new generation devices associated with increased procedural safety. They represent the standard strategy for patients with prohibitive risk for open surgery. These procedures are associated with a significant occurrence of both thrombotic and bleeding complications, thus in this setting, even more than in other percutaneous procedures, the balance between thrombotic and bleeding risk is critical...

A 70-year-old woman with back pain was diagnosed with adult anomalous origin of the left coronary artery from the pulmonary artery [Bland-White-Garland (BWG) syndrome]. Preoperative transthoracic echocardiography showed diffuse hypokinesia of the left ventricle and mild mitral valve regurgitation. Coronary angiography revealed dilatation of both coronary arteries, but no aneurysms. The left coronary ostium was removed as buttons of the pulmonary arterial wall, and a prosthetic graft (8 mm ePTFE graft) was interposed between the ascending aorta and coronary button...
