Introduction Moderate mitral regurgitation (MR) of ischemic etiology has been associated with worse outcomes after coronary artery bypass grafting (CABG). Studies comparing concomitant mitral valve replacement/repair (MVR/Re) with CABG and standalone CABG have reported conflicting results. We performed a systematic review and meta-analysis of the published literature. Patients and Methods We searched using PubMed, Cochrane, EMBASE, CINAHL, and Google scholar databases from January 1960 to June 2016 for clinical trials comparing CABG to CABG + MVR/Re for moderate MR...

BACKGROUND: Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation. However, this simplified assumption only holds when the EROA is circular, which might not be true in dogs with myxomatous mitral valve disease (MMVD). HYPOTHESIS: Effective regurgitant orifice area in dogs with MMVD is noncircular, and using color Doppler real-time 3-dimensional (RT3D) echocardiography, measured EROA in the en face view will be significantly different from calculated EROA...

OBJECTIVES: We sought to investigate a new angiographic method for aortic regurgitation (AR) severity assessment in the setting of transcatheter aortic valve implantation (TAVI). BACKGROUND: AR after TAVI is common but challenging to quantitate, especially in the cath-lab. METHODS: In 228 patients, AR was quantitated before and after TAVI by echocardiography and by video-densitometric analysis of aortograms. Contrast time-density curves for the aortic root (the reference region) and the left ventricular outflow tract, LVOT were generated...

Decreased coaptation height in adults has been identified as a marker of early valve failure. We evaluated aortic valve coaptation and effective height in healthy children and in children with a ventricular septal defect (VSD) with aortic cusp prolapse (ACP), using echocardiography. We included 45 subjects with VSD with ACP, 27 did not develop aortic regurgitation (AR) by ACP and 18 developed AR by ACP, and 83 healthy children as controls. Aortic root anatomy was estimated using the parasternal long-axis view...

OBJECTIVES: The aim of this study was to investigate the mutual influence of valvular calcifications and transcatheter aortic valve stent geometry during and after implantation of a balloon-expandable SAPIEN(®)/SAPIEN XT(®) prostheses. Aortic valve calcification has been linked with adverse complications after transcatheter aortic valve implantation (TAVI). However, little is known about the fate of the calcifications after TAVI as well as its influence on transcatheter heart valve geometry...

The adjustable slipknot technique is a novel procedure for implanting neochordae. The neochorda acts like a lasso. The procedure facilitates accurate assessment of the length of the neochordae. We performed repairs for 30 of 31 (97.7%) patients using this technique. Less than mild residual regurgitation was observed in all patients at hospital discharge.

OBJECTIVES: This study sought to explore the impact of balloon post-dilation (BPD) on outcomes in the CoreValve US Clinical Trials. BACKGROUND: BPD following transcatheter aortic valve replacement (TAVR) has been used in selected cases to optimize hemodynamic results. METHODS: Procedural details of 3,532 patients were examined to determine whether BPD was performed after self-expanding TAVR. "Best practice" guidelines recommended BPD for treatment of suboptimal intraprocedural valve function, primarily manifested by moderate or severe residual aortic regurgitation (AR)...

BACKGROUND: In pediatric patients with connective tissue disorders (CTDs), early cardiac presentation often involves severe mitral regurgitation (MR) associated with severe bileaflet prolapse and, less frequently, aortic root enlargement. We adopted a simplified repair to address MR and prevent systolic anterior motion (SAM) in this unique group of patients. MATERIALS AND METHODS: Retrospective review of clinical and echocardiographic data of all pediatric patients (age < 18 years) with CTD and MR undergoing simplified repair at 3 institutions (2000-2014)...

REVIEW
Abhishek Sharma, Sahil Agrawal, Sunny Goel, Jeffrey S Borer
PURPOSE OF REVIEW: Ischemic mitral regurgitation (MR), which occurs in about 20-30% patients with a prior myocardial infarction, is associated with worsening heart failure and an increase in cardiovascular mortality. It should be treated surgically if certain hemodynamic severity criteria are met and in patients who continue to experience symptoms of heart failure despite optimal medical therapy. However, current guidelines do not suggest which of the available approaches to mitral valve surgery-mitral valve (MV) repair or replacement (MVR) is superior for this indication...

Surgical intervention for severe tricuspid regurgitation secondary to remote infective endocarditis has been infrequent, especially in patients also infected with the human immunodeficiency virus (HIV). We describe the case of a 62-year-old HIV-positive man, with a 24-year history of endocarditis caused by intravenous heroin use, who presented with severe tricuspid regurgitation. The patient was initially asymptomatic, was taking antiretroviral medications, and had a satisfactory CD4 count and an undetectable viral load, so we decided to manage the regurgitation conservatively...

An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function...

BACKGROUND: Computed tomography angiography (CTA) is the test of choice for pre-procedure imaging of transcatheter aortic valve replacement (TAVR) candidates. The iodinated contrast required, however, increases the risk of renal dysfunction in patients with pre-existing renal failure. Ferumoxytol is a magnetic resonance imaging (MRI) contrast agent that can be used with renal failure. Its long vascular resonance time allows gated MRA sequences that approach CTA in image quality. We present respiratory and cardiac gated MRA enabled by ferumoxytol that can be post-processed in an analogous fashion to CTA...

Objective: To compare the outcome of surgical high-risk elderly patients with severe aortic stenosis(SAS) treated by different therapy procedures, including transcatheter aortic valve implantation(TAVI), surgical aortic valve replacement(SAVR), and drug therapy. Methods: We retrospectively analyzed the clinical data of 242 surgical high-risk elderly (age ≥65 years old) SAS patients hospitalized in Fuwai Hospital between September 2012 and June 2015. According to the treatment method, patients were divided into TAVI group (81 cases), SAVR group (59 cases) and drug therapy group (102 cases)...
