The quadricuspid aortic valve (QAV) is a very uncommon congenital malformation with an estimated incidence of 0.003% to 0.043% of all congenital heart diseases. Combinations of QAV with several different congenital malformations have been described. The case is reported of a type A QAV associated with moderate aortic regurgitation, mild mitral regurgitation, and ascending aorta dilatation. This interesting case was referred for close follow up.

A 58-year-old man with a history of hypertension presented with accelerating angina. Transthoracic echocardiography revealed a thickened aortic valve with pressure gradients and an estimated aortic valve area suggestive of mild aortic stenosis. Left heart catheterization demonstrated non-significant coronary artery disease. Pressure tracings showed a high left ventricular pressure and a mean gradient across the aortic valve of 69 mmHg. Subsequent transesophageal echocardiography revealed a subvalvular aortic stenosis that was secondary to the subaortic membrane, with severe valvular aortic stenosis...

In Europe, mitral regurgitation (MR) is the second most common form of valvular heart disease requiring surgical treatment. The case is presented of a 36-year-old woman with end-stage heart failure secondary to chemotherapy-induced cardiotoxicity, complicated by severe MR. She was listed for heart transplantation and underwent percutaneous MitraClip® implantation in order to preclude further clinical deterioration while awaiting a suitable donor. The one-year follow-up showed a strong improvement of symptoms and mostly reverse left ventricular remodelling, with consequent removal from the heart transplantation list...

A 21-year-old man with Wolff-Parkinson-White syndrome presented to the authors' hospital with ventricular fibrillation. Coronary angiography failed to demonstrate coronary stenosis, but temporary mechanical circulatory support resolved the ventricular fibrillation and the patient was extubated eight days later. On the next day, however, he had to be re-intubated with symptoms of congestive heart failure. Echocardiography revealed new severe mitral regurgitation and a mobile mass, while emergency surgery revealed a posteromedial papillary muscle rupture (PMR)...

Papillary fibroelastomas (PFEs) are rare and benign cardiac tumors which usually are localized on the valves (mostly on the aortic valve), though they may originate also from the ventricles or atrial walls. Whilst, in the large majority of cases, these lesions are asymptomatic they may cause serious complications such as thromboembolic events, or more rarely valvular dysfunctions. Surgical excision is necessary for a symptomatic lesion. The management of asymptomatic lesions is not defined. Herein are reported the details of a miniseries of six cases operated on at the authors' institution between 2005 and 2015...

Infective endocarditis is a challenging clinical problem with a high rate of mortality. Early recognition of this disease, and especially its complications, remain a critical task for the cardiologist. In this scenario, atrial endocarditis is a rare and sometimes unrecognized complication of mitral valve endocarditis. Herein is reported a clinical case that shows how a satellite vegetation in the atrial septum can be produced in a patient with mitral regurgitation secondary to mitral valve endocarditis. Video 1: Transthoracic echocardiography showing the presence of vegetation in the posterior mitral leaflet, severe secondary mitral regurgitation, and satellite vegetation in the atrial septum...

Insil Jang, Sukjung Choo, Kyunghee Kim
BACKGROUND: Mechanical valve replacement is associated with positive outcomes, but patients must undergo life-long anticoagulation therapy with warfarin, which carries a significant risk of bleeding complications. Therefore, a systematic and continuous assessment and supervision of warfarin treatment is essential in such patients, and approaches that can predict the risk of bleeding in advance are required. The study aim was to develop a classification tool to predict bleeding events in South Korean patients with mechanical valve replacement undergoing oral warfarin therapy...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...

Infective endocarditis (IE) is a severe disease with high mortality and morbidity. Prosthetic valve endocarditis is a life-threatening complication which can occur in less than 10% of patients with valve prosthesis. A fungal etiology of IE is rare and accounts for only 2-4% of all case of endocarditis, but is associated with a higher mortality and morbidity. Herein is reported the first case of fungal endocarditis of aortic valve prosthesis due to Aspergillus oryzae in a 67-year-old caucasian man who nine years previously underwent mitral and aortic valve replacement with mechanical prostheses, and tricuspid annuloplasty for acute IE due to Enterococcus spp...

BACKGROUND: The study aim was to investigate the safety and effects of fasting during Ramadan on the International Normalized Ratio (INR) in patients with mechanical cardiac valves. METHODS: A total of 105 patients admitted to the authors' hospital between June and October 2015, who had history of prosthetic valve replacement, was investigated. The patients were allocated to two groups: those fasting during Ramadan (n = 42) and those not fasting (n = 63). All patients were examined by a cardiologist, and the clinical findings and complaints for the past three months were evaluated...

BACKGROUND: QishenYiqi Dripping Pill (QYDP) is a Chinese herbal medicine that originally was used for the treatment of coronary artery disease. Recently, QYDP was used as a complementary treatment for heart failure (HF) in China. METHODS: An HF rat model was used to clarify the possible therapeutic effects of QYDP on HF. The HF rats were allocated to two groups, HF and HF+QYDP, while normal rats served as a negative control. Cardiac functions were evaluated echocardiographically and hemodynamically...

BACKGROUND: The isolation of high-quality RNA is an important first step in gene expression studies. However, difficult tissue disruption, low cell content and low RNA content makes consistent RNA extraction from human aortic valve tissue a challenging task. METHODS: A protocol has been developed for the successful isolation of high-quality RNA from human aortic valve samples by optimizing RNA extraction protocols based on a comparison of commercial kits. RESULTS: Guanidinium thiocyanate-phenolchloroform extraction was found to be a prerequisite for successful purification...

BACKGROUND: Atrial fibrillation is present in 30-50% of patients undergoing percutaneous mitral valve repair. The presence of a formal contraindication to oral anticoagulation is also very common in these patients. In this context, percutaneous left atrial appendage occlusion (LAAO) may be a valid alternative for these patients. The study aim was to assess the feasibility, safety, and technical considerations of the combination of percutaneous mitral valve repair using the MitraClip system and LAAO...

BACKGROUND: Acute severe mitral regurgitation (MR) is a serious medical condition. Whilst clear guidelines exist regarding the management of chronic MR, acute severe MR is usually treated on an individual basis. Currently, few data exist regarding acute MR in the era of primary coronary interventions (PCI). The present study included patients admitted to the Department of Cardiology during recent years with acute severe MR of different etiologies, and an analysis of these data in the light of previous investigations...

BACKGROUND: Minimally invasive aortic valve replacement (MIAVR) through a mini-thoracotomy is comparable to AVR through a sternotomy, but may have increased surgical times. The development of adjuncts such as the automatic knot fastener and percutaneous coronary sinus (CS) catheter may reduce this disadvantage. METHODS: A retrospective review conducted between 2002 and 2015 at a single institution revealed 78 patients who underwent MIAVR with adjuncts. The automatic knot fastener was used on all patients, and a successful CS catheter was placed and confirmed by echocardiography in 67 patients (86%)...

BACKGROUND: An increasing number of options exist for the treatment of severe symptomatic aortic stenosis. The study aim was to compare short-term outcomes in patients undergoing surgical aortic valve replacement (SAVR), minimally invasive aortic valve replacement (MIAVR), and transcatheter aortic valve replacement (TAVR). METHODS: A multi-institutional retrospective review of 2,571 patients undergoing SAVR (n = 842), MIAVR via right anterior thoracotomy (n = 699) and TAVR (n = 1,030) between 2011 and 2014 was conducted...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an effective treatment for severe aortic stenosis in high-risk patients. Several complications related to the TAVI procedure, including aortic regurgitation (AR), cerebrovascular accident (CVA) and the requirement for permanent pacemaker (PPM), are thought to be secondary to balloon aortic valvuloplasty (BAV) before TAVI. The aim of the present review was to evaluate any beneficial role of the direct TAVI approach over BAVTAVI...
