For patients with paravalvular mitral prosthetic regurgitation, percutaneous repair is an established therapy for the treatment of symptoms of heart failure or hemolytic anemia. Percutaneous repair of paravalvular mitral regurgitation is a complex procedure with unique technical challenges, even when performed in experienced centers. Herein, the author discusses patient selection, catheter-based techniques for repair, and clinical outcomes of percutaneous repair for paravalvular mitral regurgitation.

BACKGROUND: Few therapeutic options exist for patients with severe heart failure due to obstructive hypertrophic cardiomyopathy (HCM) who are at unacceptable surgical risk. We hypothesized that percutaneous plication of the mitral valve could reduce left ventricular outflow tract (LVOT) obstruction and associated mitral regurgitation, thereby leading to amelioration of heart failure symptoms. OBJECTIVES: This study sought to evaluate the potential effectiveness of percutaneous mitral valve plication as a therapy for patients with symptomatic, obstructive HCM...

Paravalvular leak (PVL) occurs after both surgical and transcatheter valve replacement/implantation. It can lead to haemolysis, heart failure and may increase the risk of endocarditis. Percutaneous closure has significantly less morbidity than re-operation and is therefore often the therapy of choice. Percutaneous PVL closure can make an important difference for patients and can improve patient prognosis. These procedures can be intricate and larger case series and research is needed to further develop and improve these procedures...

OBJECTIVES: We aimed to assess the utility of changes in systolic and diastolic function by isoproterenol challenge in predicting symptom resolution post-myectomy in selected patients with hypertrophic cardiomyopathy (HCM) and labile obstruction. BACKGROUND: In a subset of symptomatic HCM patients without resting/provocable obstruction on noninvasive assessment, isoproterenol challenge during hemodynamic catheterization may elicit labile left ventricular outflow tract (LVOT) obstruction, and demonstrate the effect of obstruction on diastolic function...

BACKGROUND: Transcatheter mitral valve (MV) repair with the MitraClip received approval in 2013 for the treatment of prohibitive-risk patients with primary mitral regurgitation (MR). OBJECTIVES: The aim of this study was to report the initial U.S. commercial experience with transcatheter MV repair. METHODS: Data from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry on patients commercially treated with this percutaneous mitral valve repair device were analyzed...

OBJECTIVES: The aim of this study was to assess the effect of a novel hourglass-shaped balloon on reduction of paravalvular leak (PVL) in patients undergoing transcatheter aortic valve replacement (TAVR) with self-expanding prostheses. BACKGROUND: An important limitation of TAVR compared with surgical aortic valve replacement remains the higher incidence of PVL. A commonly used strategy to treat PVL is balloon postdilatation (BPD); however, the optimal technique for treating PVL after TAVR is unknown...

OBJECTIVES: To investigate the utility and safety of the GuideLiner "mother-and-child" catheter system during transradial and transfemoral percutaneous coronary intervention (PCI). BACKGROUND: In patients with complex coronary anatomy, stent delivery can be challenging and result in procedural failure and complications. The GuideLiner is a coaxial guide extension system designed to enable deep vessel engagement and facilitate device delivery. The purpose of this study was to evaluate procedural success and safety in a series of GuideLiner-facilitated PCI...

OBJECTIVE: Severe, late functional tricuspid regurgitation is characterized by annulus dilation, right ventricular enlargement, and papillary muscle displacement with leaflet tethering. However, the early stages of mild tricuspid regurgitation and its progression are poorly understood. This study examined structural heart changes in mild, early tricuspid regurgitation. METHODS: Sequential patients undergoing cardiac computed tomography and transthoracic echocardiography with tricuspid regurgitation were identified and evaluated...

Paravalvular prosthetic regurgitation is common, affecting 5-10% of surgical prostheses and 40-70% of transcatheter valves. While many patients may suffer no significant morbidity, paravalvular prosthetic regurgitation can lead to heart failure and haemolytic anaemia, and, in some studies, has been associated with impaired survival. Over the past several years, percutaneous repair of paravalvular prosthetic regurgitation has been demonstrated to be a highly efficacious therapy. When performed in experienced centres, procedural success with percutaneous repair occurs in 90% of patients...

Percutaneous repair of aortic paravalvular regurgitation can help avoid the need for repeat valve surgery. Although the initial diagnosis of paravalvular regurgitation is usually made with echocardiography, cardiac CT angiography helps to determine the site and morphology of these leaks. The utility of CT is highly dependent on the quality of the data. Herein, we describe a systematic approach to image acquisition and interpretation of cardiac CT angiography in patients with aortic paravalvular regurgitation, which integrates findings from echocardiography...

The rationale to perform left ventriculography at the time of cardiac catheterization has been little studied. The technique and frequency of use of left ventriculography vary by geographic regions, institutions, and individuals. Despite the recent publication of guidelines and appropriate use criteria for coronary angiography, revascularization, and noninvasive imaging, to date there have been no specific guidelines on the performance of left ventriculography. When left ventriculography is performed, proper technique must be used to generate high quality data which can direct patient management...

OBJECTIVE: Low-gradient (LG) severe aortic stenosis (AS) and preserved EF with reduced stroke volume are associated with an adverse prognosis, but the relationship of stroke volume index (SVI) with mortality among a range of values is unknown. We investigated the prognostic impact of SVI in this population. METHODS: We examined 405 consecutive patients with preserved EF (≥50%) and severe AS (valve area <1.0 cm(2)) with LG (<40 mm Hg) using echocardiography...

OBJECTIVE: To determine the frequency and clinical impact of noncardiovascular incidental findings (IFs) detected on preoperative computed tomographic angiography (CTA) of the chest/abdomen/pelvis performed in elderly patients with severe aortic stenosis being considered for transcatheter aortic valve replacement (TAVR). PATIENTS AND METHODS: The CTA studies for 424 consecutive patients being evaluated for TAVR between January 1, 2009, through January 24, 2012, were reviewed for noncardiovascular IFs (62...
