Current Doppler echocardiography quantification of mitral regurgitation (MR) severity has shortcomings. Proximal isovelocity surface area (PISA)-based methods, for example, are unable to account for the fact that ultrasound Doppler can measure only one velocity component: toward or away from the transducer. In the present study, we used ultrasound-based computational fluid dynamics (Ub-CFD) to quantify mitral regurgitation and study its advantages and disadvantages compared with 2-D and 3-D PISA methods. For Ub-CFD, patient-specific mitral valve geometry and velocity data were obtained from clinical ultrasound followed by 3-D CFD simulations at an assumed flow rate...

OBJECTIVE: Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. METHODS: We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified incidence of each VHD and adjusted comorbidity profiles were assessed...

We present a rare case of mitral regurgitation with anterior mitral leaflet perforation associated with gelatin-resorcinol-formaldehyde (GRF) glue. We performed mitral valve replacement for anterior mitral leaflet perforation occurred 7 years after aortic valve replacement and abscess cavity repair using GRF glue. Long-term follow-up is needed for patients who have undergone surgeries using GRF glue or BioGlue (CryoLife, Inc, Kennesaw, GA) because of the possibility of late complications. In particular, when an eccentric mitral regurgitation is observed after aortic root surgery using GRF glue or BioGlue, anterior mitral leaflet perforation should be considered...

Depending from the etiology of mitral valve pathology and surgical risk, mitral valve surgery is the therapy of choice for most degenerative mitral valve diseases. In isolated secondary mitral valve regurgitation, the indication for interventional or conservative therapy becomes more important. In severe left ventricular dysfunction heart transplantation has to be taken into consideration. If relevant coronary artery disease is present and bypass surgery is indicated, mitral valve surgery is mandatory in severe regurgitation and is subject to a benefit-risk evaluation in moderate regurgitation...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary artery irregularity. This study aimed to clarify the long-term postoperative outcomes in ALCAPA patients, and to compare the infantile and adult types. METHODS: We retrospectively analyzed the clinical data from 33 patients with ALCAPA who underwent surgical repairs after 1980. The patients were grouped based on whether presentation occurred before (infantile type: n=14) or after (adult type: n=19) 1 year of age...

INTRODUCTION: A number of large-scale retrospective studies revealed that off-pump coronary artery bypass (OPCAB) was superior to on-pump coronary artery bypass (ONCAB). The aim of the study was to investigate risk factors for mortality when OPCAB is converted to ONCAB. METHODS: Patients who underwent OPCAB conversion to ONCAB at the Beijing Anzhen Hospital between January 2003 and January 2013 were assigned to the non-survivor and survivor groups. Background demographics, illness history and preoperative, intraoperative and postoperative variables were compared...

Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve repair. This change of attitude will certainly make it possible for patients to be sent for operation in mild aortic valve regurgitation...

Aims. The Assessment of left ventricular (LV) function remains a clinical challenge especially in patients with preserved LV ejection fraction (EF) and valvular heart diseases (VHD). Mechanical dispersion is supposed to be a strong predictor of events and, to be related to the extent of fibrosis. Regional cardiac work is a new validated and very promising approach to quantify LV-function. We investigated the differences in mechanical dispersions and global LV work (totW) and wasted work fraction (WWF) in normal subjects and in patients with severe primary mitral regurgitation (MR) and severe aortic stenosis (AS)...

Background: Outcome of Mitral Valve Prolapse (MVP) was controversial for long time. Many studies reported great differences in the incidence of cardiovascular events due, above all, to heterogeneous and small studied populations. Most of theme were also published to late '80 of the last century till early '00. Purpose: To make a contemporary survey on the incidence of cardiovascular events in a selected population of patients affected by primary MVP referred to a tertiary cardiovascular center for the medical and surgical care of valvular heart disease...

INTRODUCTION: A 71 year old Peruvian woman presented with blurry vision and bilateral eye pain and had evidence of bilateral endophthalmitis on eye examination. Her past medical history was notable for multiple abdominal surgeries within the preceding months, including an incarcerated inguinal hernia repair which required an ileostomy placement, and cholecystitis requiring cholecystostomy tube placement. Over her multiple long hospitalizations, she developed bacteremia and fungemia on several occasions, with organisms including Enterobacter cloacae, Klebsiella pneumoniae, Bacteroides fragilis, Pseudomonas aeruginosa, Enterococcus faecium, and Candida albicans...

INTRODUCTION: Dehiscence of a mitral valve annuloplasty ring is a rare occurrence that often manifests as mitral regurgitation and heart failure. We present a case of mitral ring dehiscence which was initially unrecognized by standard 2-dimensional transthoracic echocardiography (2D TTE); and 2-dimensional transesophageal echocardiography (2D TEE);. CASE: A 65-year-old woman was referred to Cardiology clinic for evaluation of dyspnea. Her history included tobacco abuse, atrial fibrillation status post pulmonary vein isolation, nonischemic cardiomyopathy, and prior mitral valve repair with annuloplasty ring for rheumatic valvular disease...

Severe mitral regurgitation (MR) in patients after cardiac transplant has not been well studied. Traditionally, patients have undergone corrective surgery. We report a 64-year-old man who presented with new heart failure symptoms 6 months after cardiac transplantation. He was found to have severe MR and underwent successful implantation of a MitraClip® with reduction of his MR to mild as well as improvement in his symptoms. Six months later he was still doing well, and a repeat echocardiogram showed good results...

BACKGROUND: Bileaflet mitral valve prolapse (biMVP) is associated with frequent ventricular ectopy (VE) and malignant ventricular arrhythmia. We examined the effect of mitral valve (MV) surgery on VE burden in biMVP patients. METHODS: We included 32 consecutive patients undergoing MV surgery for mitral regurgitation secondary to biMVP between 1993 and 2012 at Mayo Clinic who had available pre- and post-operative Holter monitoring data. Characteristics of patients with a significant reduction in postoperative VE (group A, defined as >10% reduction in VE burden compared to baseline) were compared with the rest of study patients (group B)...
