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'...

In literature, there are limited data comparing ischemic mitral regurgitation (I-MR) versus nonischemic MR regarding outcomes after percutaneous "edge-to-edge" repair. We aimed to describe the early and 12-month results after MitraClip device implantation regarding the 2 etiologies. From January 2011 to December 2012, the Transcatheter Valve Treatment Sentinel Pilot Registry included 452 patients with MR who underwent MitraClip procedure in 25 centers across Europe. The prevalent etiology was I-MR (235 patients, 52...

Heart failure and severe mitral regurgitation (MR) are mutually dependent. Secondary MR is a consequence of chronic heart failure in patients with severely depressed left ventricular ejection fraction (LV-EF) and LV dilatation. Severe MR in heart failure patients worsens prognosis and accelerates LV dilatation and decline in LV-EF. Interventional therapies have changed clinical practice for heart failure patients with secondary MR. In this review we summarize the available data of patients with chronic heart failure undergoing transcatheter edge-to-edge mitral valve repair (TMVR) with the MitraClip® system for severe secondary mitral regurgitation...

The purpose of this European Heart Rhythm Association (EHRA) Survey was to assess the perceptions of 'valvular' atrial fibrillation (AF) and management of AF patients with various heart valve abnormalities in daily clinical practice in European electrophysiology (EP) centres. Questionnaire survey was sent via the Internet to the EHRA-EP Research Network Centres. Of the 52 responding centres, 42 (80.8%) were university hospitals. Choosing the most comprehensive definition of valvular AF, a total of 49 centres (94...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...

REVIEW
Jeffrey M Paulsen, Thomas W Smith
Echocardiography continues to be the most effective imaging tool for the diagnosis and follow-up of mitral valve disease. This review addresses the use of transthoracic echocardiography and transesophageal echocardiography in the planning and guidance of transcatheter mitral valve therapies. Many of the echo-imaging guidance techniques are applicable to transcatheter intervention as a whole. However, given that the MitraClip is the only device approved for mitral regurgitation at present, specific attention is paid to this procedure, with additional focus on the guidance of noncentral repair...

REVIEW

Valve-in-valve and valve-in-ring transcatheter mitral valve replacement can be used in for the treatment of inoperable patients with failing mitral surgical bioprosthesis or valve repairs. Preprocedural multi-image evaluation by a heart team must include transthoracic echocardiogram, transesophageal echocardiogram, and cardiac computed tomography angiography (CTA). CTA is used to determine access site (transapical, transseptal, or transatrial), transcatheter valve size, and landing zone. Though complications can occur (ie, valve embolization, bleeding, or vascular complications), this less invasive procedure has a reported success rate of 70% to 100% and is now increasingly used...

OBJECTIVES: A thorough understanding of mitral and aortic valve motion dynamics is essential in mastering the skills necessary for performing successful valve intervention (open or transcatheter repair or replacement). We describe a reproducible and versatile beating-heart mitral and aortic valve assessment and valve intervention training model in human cadavers. METHODS: The model is constructed by bilateral ligation of the pulmonary veins, ligation of the supra-aortic arteries, creating a shunt between the descending thoracic aorta and the left atrial appendage with a vascular prosthesis, anastomizing a vascular prosthesis to the apex and positioning an intra-aortic balloon pump (IABP) in the vascular prosthesis, cross-clamping the descending thoracic aorta, and finally placing a fluid line in the shunt prosthesis...

Advancements in surgical technique and understanding of the pathophysiology of mitral valve (MV) dysfunction have led to improved outcomes. Seen as a development beyond measures of morbidity and mortality, health-related quality-of-life (HRQOL) outcome measures are becoming increasingly popular. These measures are important because complications following routine (i.e. low-risk) operations on the MV are uncommon and further markers of outcome are needed. Surgeons are increasingly operating earlier on asymptomatic patients and will need to prove that HRQOL is not impacted...

AIMS: Mitral annular calcification (MAC) negatively influences outcomes in surgical mitral valve (MV) repair for mitral regurgitation (MR). However, there are no data on whether MAC impacts on outcomes of MitraClip percutaneous MV edge-to-edge repair. This study sought to investigate whether the presence of MAC impacts on the procedural success and durability of percutaneous transcatheter repair of MR using the MitraClip. METHODS AND RESULTS: One hundred and seventy-three patients undergoing MitraClip repair for significant MR were studied...

Most mitral paravalvular leaks (PVLs) occur during the first year after mitral valve replacement (MVR). This report describes the surgical management of 6 patients who developed very late mitral PVLs. The median interval between MVR and initial diagnosis of PVL was 16.5 years. All patients presented with congestive cardiac failure and haemolytic anaemia. The median EuroSCORE II was 9.5%. Two patients (33%) had failed attempts at transcatheter closure. Five patients underwent suture repair of the PVL. One patient underwent MVR after removal of the previous prosthesis...
