OBJECTIVES: Mitral valve (MV) repair is the gold standard for treatment of degenerative mitral regurgitation. A variety of surgical techniques allow surgeons to achieve a high rate of MV repair even with MV diseases of other aetiologies. However, a certain number of repairs fail over time. The aim of this study was to review our single-centre experience of MV re-repair and analyse the mode of repair failure, re-repair safety and efficiency in relation to the initial aetiology. METHODS: Between 1997 and 2015, 91 patients underwent redo MV re-repair...

INTRODUCTION: Cardiovascular complications represent the leading cause of morbidity and mortality in patients with Marfan syndrome. Here, we describe a unique case where a total artificial heart was implanted in a young Marfan syndrome woman. METHODS: A 22-year-old postpartum African American female with Marfan syndrome developed multiple severe valve dysfunction and biventricular failure that was refractory to medical management. She previously had a Bentall procedure for Type A aortic dissection and repair of a Type B dissection...

PURPOSE OF REVIEW: The past couple of decades have brought tremendous advances to the field of pediatric and adult congenital heart disease (CHD). Percutaneous valve interventions are now a cornerstone of not just the congenital cardiologist treating patients with congenital heart disease, but also-and numerically more importantly-for adult interventional cardiologists treating patients with acquired heart valve disease. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with right ventricular outflow tract (RVOT) dysfunction...

OBJECTIVES: Postoperative left pulmonary artery (PA) or bronchus compression occasionally follows narrowing of the retroaortic space after the Norwood procedure. We examined hypoplastic left heart syndrome (HLHS)-specific anatomical malformations and hypothesized that a long main pulmonary arterial trunk might contribute to a larger retroaortic space. In this study, we introduced a modified Norwood procedure [pulmonary artery trunk-saving method (PATS)] and evaluated the results. METHODS: HLHS-specific anatomical malformations were examined using computed tomographic data from 23 consecutive patients who underwent bilateral pulmonary banding...

BACKGROUND: Percutaneous mitral valve edge-to-edge repair (pMVR) with a MitraClip is beneficial for the clinical symptoms of patients irrespective of the ejection fraction (EF). Nevertheless, the consequences on hemodynamics are poorly understood. Therefore, we used data from noninvasive pressure-volume loops to investigate the left ventricular (LV) remodeling of patients after pMVR dependent on their baseline EF. METHODS AND RESULTS: In 130 patients with successful pMVR, the end-diastolic pressure-volume relationship (EDPVR) and end-systolic pressure-volume relationship were estimated noninvasively from echocardiographic data...

OBJECTIVE: To assess the results of catheter-based and surgical reintervention in primary mitral regurgitation (PMR) after failed MitraClip therapy. METHODS: We report on 21 consecutive symptomatic patients with PMR (median age 78 years) who underwent either repeat MitraClip therapy (n=7) or mitral valve surgery (n=14) after failure of the index procedure with 1-2 MitraClip implantations. At the time of reinterventions, 193 [IQR: 32 to 622] days after index procedure, patients had recurrent or persistent grade 3 MR...

AIMS: We compared thromboembolic (TE) and bleeding risks in patients with atrial fibrillation (AF) according to the new 'Evaluated Heartvalves, Rheumatic or Artificial' (EHRA) valve classification. METHODS: Patients were divided into 3 categories: (i) EHRA type 1 corresponds to the previous 'valvular' AF patients, with either rheumatic mitral valve stenosis or mechanical prosthetic heart valves; (ii) EHRA type 2 includes AF patients with other valvular heart disease (VHD) and valve bioprosthesis or repair; and (iii) 'non-VHD controls' i...

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR...

The feasibility and durability of mitral valve (MV) repair in active infective endocarditis (IE) has been reported, but proper management of perioperative neurological complications and surgical timing remains uncertain and may crucially affect the outcome.In this single-center retrospective observational study, patients who underwent isolated MV surgery for active native IE in our institution between August 2005 and August 2015 were reviewed and analyzed. Patients who were operated on for healed IE or who required combined procedures were excluded from this study...

BACKGROUND: Mitral regurgitation is the most common valve disease worldwide but whether the community-wide prevalence, poor patient outcomes, and low rates of surgical treatment justify costly development of new therapeutic interventions remains uncertain. Therefore, we did an observational cohort study to assess the clinical characteristics, outcomes, and degree of undertreatment of mitral regurgitation in a community setting. METHODS: We used data from Mayo Clinic electronic health records and the Rochester Epidemiology Project to identify all cases of moderate or severe isolated single-valvular mitral regurgitation (with no other severe left-sided valvular disease or previous mitral surgery) diagnosed during a 10-year period in the community setting in Olmsted County (MN, USA)...

OBJECTIVE: Mitral valve repair using an undersized complete annuloplasty ring in secondary mitral regurgitation with restricted leaflet motion during systole (Carpentier's surgical classification of mitral valve pathology: type IIIb) only inadequately addresses the underlying left ventricular disease. This may lead to an ongoing ventricular remodelling and progressive papillary muscle displacement with increasing leaflet tethering. Several subannular techniques have been proposed to counteract the reoccurrence of mitral regurgitation after mitral valve repair...

BACKGROUND: Although reverse remodeling of the left atrium (LA) has been shown after MitraClip placement in degenerative mitral regurgitation (MR), changes in LA strain and strain rate have not been evaluated in these patients or compared with surgical mitral valve repair. METHODS AND RESULTS: We included 87 subjects (mean age 59.7±12.3 years) with degenerative MR enrolled in the randomized EVEREST II trial (Endovascular Valve Edge-to-Edge Repair Study II). Baseline peak positive LA strain (ε) and strain rates along with longitudinal left ventricular strain (LV ε) were compared with 12-month follow-up measures...

Although vancomycin administration is recommended for the treatment of infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA), it is unclear whether an alternative agent, daptomycin, can be used to treat IE with pulmonary complications. A 26-year-old female who had undergone surgical repair of a ventricular septal defect as an early teenager presented with fever, headache, and vomiting. She was admitted to our hospital and diagnosed with right-sided IE with septic pulmonary embolism caused by MRSA...

OBJECTIVES: The technique of subcoronary autograft implantation for the Ross procedure has shown excellent durability of aortic valve function in adults. However, its use in children with hypoplastic aortic annulus or multilevel left ventricular outflow tract obstruction (LVOTO) was traditionally precluded. We combined this technique with a Konno incision and evaluated LVOTO relief and durability of the autograft function in growing patients. METHODS: Between January 2012 and January 2017, 13 patients with severe LVOTO and hypoplastic aortic annulus underwent Ross-Konno procedure with subcoronary autograft implantation...

BACKGROUND: Ischemic mitral regurgitation (IMR) is a frequent complication of coronary artery heart disease and is associated with increased mortality. Controversies exists whether patients with moderate IMR may benefit from a combined procedure with coronary artery bypass grafting (CABG) and treatment of mitral regurgitation. METHODS: 451 patients with moderate IMR (grade 2) receiving either CABG alone (CABG only) or additional mitral valve repair or replacement (CABG+MV) were included in this observational single-centre study...

OBJECTIVES: Mitral regurgitation (MR) in the majority of infants with an anomalous left coronary artery from the pulmonary artery (ALCAPA) has been shown to improve without concomitant mitral valve repair. However, the outcome of MR in older children with ALCAPA is unclear. The purpose of this study was to compare the outcome of MR following the ALCAPA repair in infants and older children. METHODS: Forty-six patients (34 were younger than 1 year and 12 were aged 1-12 years) underwent the repair for ALCAPA in our institution from June 2006 to June 2016...
