Co-morbidities increase markedly with aging, and they often negatively affect its prognosis. Although mortality with transcatheter mitral valve repair (TMVr) is significantly less than for open mitral valve surgery in patients at high surgical risk, it remains a concern to identify which patients will benefit from this treatment. Some prognostic metrics have been reported to guide better patient selection; however, universal risk stratification measures have not been established. This study aimed to determine if age-adjusted Charlson co-morbidity index (CCI) could predict mortality in patients who underwent TMVr and to assess its discriminatory performance in long-term outcomes...

We describe herein 2 patients who developed severe mitral stenosis (MS) approximately two decades after a mitral valve repair operation for pure mitral regurgitation (MR) secondary to mitral valve prolapse. This report's purpose is to point out that use of a circumferential mitral annular ring during the repair has the potential to produce a transmitral pressure gradient just like that occurring after mitral valve replacement utilizing a mechanical prosthesis or a bioprosthesis in the mitral position.

We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

BACKGROUND: Cardiac valve disease is common in patients with end-stage heart failure undergoing left ventricular assist device implantation (LVAD). The aim of this study was to determine if preoperative mitral regurgitation (MR) affects outcomes and hemodynamics in patients after LVAD implantation. METHODS: From March 2006 through May 2015, 238 consecutive patients underwent LVAD implantation. Patient cohorts included less than moderate to severe MR (< moderate-severe, n = 195) and greater than or equal to moderate to severe MR (≥ moderate-severe, n = 43)...

A 74-year-old man with a history of mitral valve repair was referred to our hospital with fever and diagnosed with mitral valve endocarditis involving occlusion of the superior mesenteric artery. Bacterial cultures showed Staphylococcus lugdunensis. Despite antibiotic therapy, orthopnea ensued due to valve destruction. Emergency mitral valve replacement was performed. Computed tomography on postoperative day 10 revealed a rapidly expanding mycotic aneurysm of the superior mesenteric artery. Aneurysmectomy was undertaken...

The current non-resectional paradigm in mitral valve (MV) repair emphasizes the use of polytetrafluoroethylene (PTFE) for artificial chordal replacement. While excellent long-term durability of repair using PTFE neochordae has been established, there have been rare reports of neochordal rupture at various times after surgery. We report a case of artificial chordal rupture 10 years after anterior mitral leaflet repair, necessitating reoperation. This complication may have been precipitated by maldistributed intracardiac tensile forces as a consequence of a malpositioned annuloplasty band...

BACKGROUND: Adults with congenital heart disease (ACHD) undergoing systemic atrioventricular valve (SAVV) surgery are a complex, understudied population. We assessed midterm outcomes and prognostic factors in ACHD undergoing SAVV surgery. METHODS: We performed retrospective evaluation of ACHD undergoing SAVV surgery from January 2005 to February 2016: 14 (33%) patients with congenital mitral valve stenosis/regurgitation, 15 (35%) with atrioventricular septal defect (AVSD), and 14 (33%) with congenitally corrected transposition of the great arteries (ccTGA) with systemic tricuspid valve regurgitation...

We report a clinical case of a 40-year-old male with surgically corrected congenital heart disease (CHD) 10 years earlier: closure of ostium primum, mitral annuloplasty, and aortic valve and root surgery. The patient was admitted with acute heart failure. Transesophageal echocardiography (TEE) revealed a dysmorphic and severely incompetent aortic valve, a partial tear of the mitral valve cleft repair and annuloplasty ring dehiscence. A true left ventricular-to-right atrial shunt confirmed a direct Gerbode defect...

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible...

We report about the first-in-man implantation of the Mitra-SpacerTM (Cardiosolutions Inc., West Bridgewater, MA/USA). It was implanted transapically. FMR was reduced to moderate degree. At two-months, while in NYHA II, LVEF had improved, but FMR increased and 2mL was added, reducing FMR to mild degree. Despite anticoagulation, thrombi developed around the device and the valve was replaced at eight-months. The Mitra-SpacerTM successfully bridged this patient to surgery after LVEF had recovered.

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

BACKGROUND: Tricuspid valve (TV) repair at the time of left-sided valve surgery is indicated in patients with either severe functional tricuspid regurgitation (TR) or mild-to-moderate TR with coexistent tricuspid annular dilation or right heart failure. We assessed the benefits of a concomitant TV repair strategy during left-sided surgical valve interventions, focusing on mortality and echocardiographic TR-related outcomes. METHODS: A meta-analysis was performed of studies reporting outcomes of patients who underwent left-sided (mitral and/or aortic) valve surgery with or without concomitant TV repair...

The objective of this study was to investigate the usefulness of intraprocedural hemodynamic monitoring for MR evaluation during pMRV. Assessment of mitral regurgitation (MR) during percutaneous mitral valve repair (pMVR) procedure is challenging. 3D color Doppler allows exact quantification of MR, but is technically demanding. Sixty patients with moderate to severe MR (14 with structural and 46 functional MR) were included in the study. Intraprocedural pressure curves were continuously obtained in the left atrium (LA) and left ventricle (LV)...

Echocardiography is the most used imaging technique for the study of patients with mitral regurgitation because of its wide distribution, non-invasiveness and ability to provide diagnostic, functional, hemodynamic and prognostic evaluations. Also, echocardiography can provide essential information on surgical and percutaneous reparability of the regurgitant valve and can guide the surgical and interventional indications relative to valve repair. However, the echocardiographic study is not always appropriately performed in clinical practice and based on a surgery perspective...
