OBJECTIVES: Sutureless aortic valve replacement (SU-AVR) is an alternative technique to standard aortic valve replacement. We evaluated our experience with the Perceval SU-AVR with concomitant mitral valve surgery, with or without tricuspid valve surgery, and aimed to discuss the technical considerations. METHODS: From January 2013 through June 2016, 30 patients with concomitant severe mitral valve disease, with or without tricuspid valve disease, underwent SU-AVR with the Perceval prosthesis in a single center...

Evaluation of antiphospholipid antibodies (aPL) and correlation with heart valve abnormalities among patients with systemic lupus erythematosus (SLE). Nested case-control study was conducted with 70 patients with SLE selected from a longitudinal database based on levels of aPL and presence or absence of valve disease by echocardiogram. Valvular abnormalities observed were regurgitation (52), other (14), artificial valves (4), stenosis (2), thickening (2) and no Libman-Sacks endocarditis (0). The mitral valve was the most commonly affected (30 abnormalities), followed by the tricuspid (20 abnormalities)...

BACKGROUND: Valvular heart disease is a leading cause of cardiovascular mortality, especially in China. More than a half of valvular heart diseases are caused by acute rheumatic fever. microRNA is involved in many physiological and pathological processes. However, the miRNA profile of the rheumatic valvular heart disease is unknown. This research is to discuss microRNAs and their target gene pathways involved in rheumatic heart valve disease. METHODS: Serum miRNA from one healthy individual and four rheumatic heart disease patients were sequenced...

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...

Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

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...

BACKGROUND: Atrial fibrillation (AF) can occur even after the correction of mitral valve (MV) pathology in patients who have pre-operative sinus rhythm and undergo MV surgery. However, the factors associated with the occurrence of AF after MV surgery are still unclear. The aim of this retrospective study was to investigate the factors determining the occurrence of permanent AF after MV surgery in patients with preoperative sinus rhythm who underwent MV surgery. METHODS: Four hundred and forty-two patients (mean age 46 ± 12, 190 men) who underwent MV surgery and sinus rhythm were investigated retrospectively...

This prospective multicentre observational study investigated the risk of non-cardiac surgery in patients with moderate or severe aortic stenosis (AS). Patients with AS undergoing non-cardiac surgery in five New Zealand hospitals between August 2011 and September 2015 were studied. Preoperative variables were analysed for a significant association with postoperative major adverse cardiac events (MACE) and 30-day mortality. Of the 147 patients recruited, 13 (9%) died within 30 days and 33 (22%) had a MACE. Using univariate analysis, patients with severe AS had four times higher 30-day mortality than patients with moderate AS (16% versus 4%, <i>P</i>=0...

Transapical transcatheter aortic valve implantation is a well-established alternative in patients at a high risk for conventional aortic valve replacement. We performed transapical transcatheter aortic valve implantation on an 83-year-old woman with symptomatic severe aortic stenosis. Intraoperative transoesophageal echocardiography (TOE) after transcatheter aortic valve implantation showed mild mitral regurgitation without intracardiac structural injury. In the intensive care unit, the patient gradually had haemodynamic instability; TOE revealed severe mitral regurgitation with A2 and A3 prolapse due to rupture of the posterior papillary muscle...

BACKGROUND: Although it has been realized that restrictive mitral valve annuloplasty (MVA) may result in clinically significant functional mitral stenosis (MS), it still cannot be predicted. The purpose of this study was to identify risk factors for clinically significant functional MS following restrictive MVA surgery for chronic ischemic mitral regurgitation (CIMR). METHODS: 114 patients who underwent restrictive MVA with coronary artery bypass grafting (CABG) for treatment of CIMR were retrospectively reviewed...

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.9 m/s, maximum gradient of 15 mmHg, mean gradient of 6 mmHg, severe tricuspid valve insufficiency, inferior vena cava measuring 15 mm with more than 50% collapse and pulmonary artery systolic pressure of 40 mmHg...

Cardiac ochronosis is a rare complication of alkaptonuria, a disorder of tyrosine metabolism characterized by a triad of dark urine, pigmentation of tissues, and ochronotic arthropathies. When present, cardiac ochronosis generally affects the aortic valve resulting in aortic stenosis. More rarely, it may affect the mitral valve and the coronary arteries. We describe the case of a 67-year-old lady with a history of alkaptonuria with severe ochronosis of the coronary arteries and mitral valve, requiring coronary bypass and mitral valve replacement...

Severe calcific mitral valve stenosis can rarely occur concomitantly with obstructive hypertrophic cardiomyopathy. In these patients, surgical decalcification of the stenotic mitral valve followed by mitral valve replacement carries significant operative risk and may result in paravalvular leakage, atrioventricular groove disruption, and excessive bleeding. We report the first 2 cases of obstructive hypertrophic cardiomyopathy with severe calcific mitral valve stenosis successfully treated with concomitant transaortic septal myectomy and bypass of the stenotic mitral valve using a valved left atrium to left ventricular conduit...

Antiphospholipid syndrome is a rare autoimmune disease with a hypercoagulable state causing vascular thrombosis. We present the case of a 42-year old female who underwent mitral valve replacement with a mechanical valve 15 months ago. The postoperative course was uneventful, and echocardiography performed 14 months postoperatively showed good valve function. The patient developed sudden dyspnea 15 months postoperatively and was referred to our hospital. Echocardiography revealed mitral stenosis with stuck leaflets...

Calcified amorphous tumor (CAT) of the heart is a rare non-neoplastic cardiac tumor. The clinical features of cardiac CATs resemble those of other cardiac tumors that include symptoms related to obstruction or embolization. Cardiac CATs have been found in all chambers of the heart, but predominantly present in the left ventricle, mitral annulus, and mitral valve. Here we report an extremely rare case of CAT originating in the aortic valve cusp, which may be related to aortic annular calcification and aortic valve stenosis...
