OBJECTIVE: Hematopoietic-derived cells have been reported in heart valves but remain poorly characterized. Interestingly, recent studies reveal infiltration of leukocytes and increased macrophages in human myxomatous mitral valves. Nevertheless, timing and contribution of macrophages in normal valves and myxomatous valve disease are still unknown. The objective is to characterize leukocytes during postnatal heart valve maturation and identify macrophage subsets in myxomatous valve disease...

PURPOSE OF REVIEW: As ventricular assist device (VAD) therapy in patients with advanced heart failure continues to grow, experience with concomitant valvular diseases present either before or after VAD implantation continues to accrue. In this review, we discuss recent data and current practice as it pertains to the subject of concomitant valvular disease in patients requiring VADs. RECENT FINDINGS: Persistent aortic valve closure has been identified as a potential contributor to aortic valve 'disuse atrophy' resulting in valve degeneration...

4D flow MRI is an emerging technique that allows quantification of 3D blood flow in vivo. However, comparisons with methods of blood velocity quantification used in clinical routine are sparse. Therefore, we compared velocity quantification using 4D flow MRI with transthoracic and transesophageal echocardiography at the mitral and aortic valves and the aorta. Forty-eight stroke patients (age 67.3 ± 15.0 years) were examined by 4D flow MRI. Blood flow velocities were assessed using standardized 2D analysis planes positioned in the mitral valve (MV), aortic valve (AV), ascending aorta (AAo), and descending aorta (DAo) and were compared with echocardiography...

Objectives: Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. Methods: The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach...

Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization. The most common sites of origin are aortic and mitral valve surfaces. We present successful surgical resection of a papillary fibroelastoma through the mitral valve which originated from the posterior papillary muscle of the left ventricle.

The outcome in functional mitral regurgitation after aortic valve replacement is unclear. A frail 82-year-old woman with severe aortic valve regurgitation and mild to moderate functional mitral valve regurgitation (NYHA functional class III) was referred to our clinic. In consideration of her frail condition, aortic valve replacement without mitral surgery was performed. She had hemodynamic instability and difficulty to wean off cardiopulmonary bypass caused by severe functional mitral valve regurgitation with left ventricular dilatation...

Background: The radiofrequency (RF) maze procedure can effectively restore sinus rhythm in most patients with persistent atrial fibrillation (AF) and mitral disease. However, long-term results and predictors for late AF recurrence are still under investigation. Methods: From December 1995 to November 2011, 207 consecutive patients with persistent AF and mitral disease underwent RF maze procedure and concomitant mitral surgery. The mean age was 54±12.4 year-old...

BACKGROUND: Ebstein anomaly is a complex, congenital heart defect that is associated with a variety of cardiac abnormalities. Studies found a similar sarcomere gene mutation in patients with Ebstein anomaly (EA) and patients with isolated left ventricular non-compaction (LVNC). AIM: We aimed to show the prevalence of LVNC and its potential relationship with severe cardiac events (VT - ventricular tachycardia, cardiac arrest) in adult patients with EA. METHODS: We conducted a retrospective search of our institutional database from 2010 to 2014 for patients with EA and reviewed patients' medical records (age, sex, clinical presentation, electrocardiographic, echocardiographic, and CMR - cardiac magnetic resonance features)...

Transcatheter heart valve replacement technology was introduced as alternative to surgery for the growing high-risk profile population. Developed first, aortic valve replacement (TAVR) became a standard of care for patients with severe aortic stenosis at high operative risk, with a potential future use also for low-risk subjects. In the last decade, a multitude of transcatheter mitral valve replacement (TMVR) devices have been developed for the treatment of severe mitral regurgitation, with encouraging results coming from first-in-man and feasibility studies...

BACKGROUND: Tricuspid valve regurgitation (TR) is often not taken into consideration in the prognostication of patients undergoing transcatheter aortic valve replacement (TAVR). Accordingly, its impact on such patients remains relatively poorly defined. The study aim was to explore the effect of TR and parameters of right ventricular (RV) function on outcomes in patients undergoing TAVR. METHODS: Baseline demographic and echocardiographic data were collected for 460 consecutive patients undergoing TAVR at the authors' institution between 2012 and 2015...

Background: Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods: A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups)...

BACKGROUND: Less-invasive mitral valve surgery has become a widespread procedure in recent years, although mode of perfusion and aortic clamping are still debated questions. The aim of this study was to compare the results between transthoracic aortic clamping (TTC) and endoaortic clamping (EAC) in a multicenter, retrospective study. METHODS: Data from 3 centers experienced in both TTC and EAC were retrospectively analyzed. Five hundred consecutive patients undergoing less-invasive mitral valve surgery received either TTC (n = 250) or EAC (n = 250)...

BACKGROUND: Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. METHODS: A retrospective analysis of 43 high-risk patients who underwent concomitant surgical aortic valve replacement and mitral valve surgery from 2008 to 2012 was performed...
