REVIEW
Barry O'Brien, Haroon Zafar, Simon De Freitas, Faisal Sharif
In recent years, the transseptal puncture approach has enabled passage of increasingly large and complex devices into the left atrium. Traditional tools remain effective in creating and dilating the initial puncture, with an acceptable safety profile. Even for skilled operators, the procedure is technically demanding and requires sound understanding of atrial anatomy. Intracardiac echocardiography is useful in cases of previous septal repair, poorly defined fossa ovalis anatomy or when considering patent foramen ovale portal crossing...

BACKGROUND: Degenerated surgical mitral valve repairs or surgical prostheses are currently being treated with transcatheter mitral valve replacement (TMVR). We report the procedural and mid-term assessment of thirteen cases. METHODS: From 12/2013 to 12/2015, 13 consecutive patients with degenerated mitral valve repair or valve replacement were treated. Patients were assessed for mitral valve academic valve consortium (MVARC) defined outcomes. RESULTS: Immediate procedural MVARC defined technical success was 92%...

A 75-year-old man presented with infective endocarditis. Transesophageal echocardiogram (TEE) revealed mild-moderate mitral regurgitation (MR). After 4 weeks of antibiotics, he presented with New York Heart Association class III dyspnea. Repeat TEE demonstrated severe MR. After consultation with Infectious Diseases, it was determined the infection risk was low and transcatheter mitral valve repair (TMVR) was offered. Deployment of two MitraClip devices (Abbott Vascular) resulted in symptom relief. This case demonstrates a potential role of TMVR in treating acute severe MR due to endocarditis...

Mitral valve regurgitation (MR) is common, with a prevalence that exceeds 9% for those patients >75 years of age. For symptomatic patients with prohibitive surgical risk, transcatheter mitral valve repair with the MitraClip(®) system (Abbott Vascular, Menlo Park, CA) is available for clinical use and is effective in reducing MR in select patients. For optimal clinical success, the procedure requires mastery of complex catheterization skills with application of an in-depth understanding of the mitral valve anatomy...

BACKGROUND: Longitudinal motion of the mitral annulus is an index that reflects left ventricular (LV) function. The aim of this study was to evaluate and compare the effects of transcatheter mitral valve (MV) repair and open heart surgery for mitral regurgitation (MR) on mitral annular motion (MAM). METHODS: We retrospectively analyzed in total 115 patients who underwent isolated transcatheter MV repair using MitraClip (n=50) or surgical MV interventions (n=65, 50 repairs and 15 replacements) for MR...

OBJECTIVE: In patients with atrial fibrillation, 90% of embolic strokes originate from the left atrial appendage (LAA). Successful exclusion of the LAA is associated with a lower stroke rate in patients with atrial fibrillation. Surgical oversewing of the LAA is often incomplete when evaluated with transesophageal echocardiogram (TEE). External closure techniques of suturing and stapling have also demonstrated high failure rates with persistent flow and large stumps. We hypothesized that the precise visualization of a robotic LAA closure (RLAAC) would result in superior closure rates...

Hybrid transcatheter Mitral Valve-in-Ring and Mitral Valve-in-Valve procedures can be an alternative to traditional surgical valve replacement in patients with high surgical risk. We present a case of a 65-year-old male with recurrent severe mitral regurgitation (MR) that failed two traditional surgical attempts due to severe chest fibrosis. We performed a mitral valve-in ring replacement with a Sapien valve followed by a mitral valve-in-valve replacement with a Melody valve. Patient had a residual paravalvular leak that was closed with a vascular plug...

AIMS: Pacemaker lead-associated severe tricuspid regurgitation (TR) can lead to right heart failure and poor prognosis. Surgery in these patients carries significant morbidities. We describe a successful treatment of symptomatic severe TR by leadless pacemaker implantation followed by tricuspid valve (TV) repair with the MitraClip NT. METHODS AND RESULTS: A 71-year-old frail female with poor functional status, chronic atrial fibrillation and permanent pacemaker implantation in 2012 presented with symptomatic moderate-severe mitral regurgitation (MR) and severe TR with the pacemaker lead as the culprit...

OBJECTIVES: To investigate in a series of 232 patients whether the MitraClip(®) procedure can be performed safely using deep sedation (DS) without general anesthesia (GA). BACKGROUND: Transcatheter mitral valve repair using the MitraClip(®) system is a safe and effective therapy for severe mitral regurgitation (MR) in patients who are at high operative risk or are unsuitable for surgery. For these patients, avoidance of GA might be beneficial. METHODS: Between 2011 and 2015, we performed 232 MitraClip(®) procedures for the treatment of severe MR...

BACKGROUND: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. METHODS: In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information...

Sutureless aortic valve replacement (AVR) was developed as an alternative treatment option to conventional open-heart surgery and transcatheter aortic valve implantation for "gray zone" patients. The need for concurrent mitral valve surgery is generally viewed as a contraindication to sutureless AVR. The purpose of this brief paper is to report our experiences with sutureless valves in patients after previous cardiac procedures with degenerated aortic bioprostheses and concomitant mitral valve disease.

AIMS: The aim of this study was to investigate the procedural feasibility and short-term durability of the transcatheter tricuspid valve edge-to-edge repair technique in highly symptomatic patients with severe tricuspid regurgitation (TR). METHODS AND RESULTS: Eighteen consecutive patients suffering from severe right-sided heart failure (NYHA Class III-IV), primarily due to moderate to severe tricuspid regurgitation, were included in the study. Applying a modified steering technique for the clip delivery system, six patients were treated for isolated severe TR, while 12 patients were treated for moderate to severe TR and concomitant severe mitral regurgitation...

Paravalvular leak (PVL) following aortic valve implantation is a rare complication but may cause potentially serious consequences. It occurs in 2%-10% of surgical aortic valve replacements and 7%-17% of surgical mitral valve replacements. Transcatheter valve replacement data show that significant PVL occurs in 6%-8% of cases. The management of significant PVL has traditionally involved repeat surgical repair. However, many of these patients are considered too high risk to undergo a repeat surgical procedure; hence, a percutaneous transcatheter approach has often been utilized to treat these patients...

Interest in minimally invasive video-assisted mitral valve surgery (MIMVS) is rapidly growing. Data on concomitant atrial fibrillation (AF) ablation to MIMVS are still lacking. The present study investigates the long-term results of AF cryoablation concomitant to MIMVS. From October 2006-September 2014, 68 patients with mitral valve disease (age 65.9 ± 11.1 years, 34 men out of 68 patients, Euroscore log 5.4 ± 4.5) and drug-resistant AF underwent MIMVS via right minithoracotomy and concomitant left-sided AF endocardial cryoablation (Cryoflex Medtronic, Minneapolis, MN)...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

An 83-year-old man with a previous mitral valve repair using a semi-rigid annuloplasty ring was found to have severe mitral stenosis. A transcatheter approach for mitral valve-in-ring replacement was selected due to the patient's high surgical risk. Pre-procedural computed tomography scans for transcatheter valve size selection were inconsistent with previously published recommendations. To determine the appropriate valve size, a 25 mm compliant balloon was inflated intraoperatively within the stenotic mitral ring, but yielded no resistance to movement and no 'waist'...
