Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

A 49-year-old female was admitted to our hospital with a history of fever for 2 weeks and consciousness disorder.Transthoracic echocardiography demonstrated aortic regurgitation with a mobile fibrous band adhering to the right cusp. Infective endocarditis was diagnosed by positive blood culture and echocardiographic findings. Emergent aortic valve surgery was performed because of uncontrollable infection. A destroyed aortic annulus and subvalvular abscess was found during the operation. Removal of abscess tissue and annuloplasty with self-pericardium were successfully performed...

INTRODUCTION AND AIM: Infective endocarditis (IE) is associated with high morbidity and mortality. It is important to determine which factors increase the risk of poor outcome in order to enable early detection and aggressive treatment, including surgery. The aim of our study was to identify factors predicting complications and in-hospital mortality in patients with IE and to analyze conditions predisposing to surgery and its outcome. METHODS: We performed a retrospective study including patients with IE who underwent transesophageal echocardiography in a tertiary hospital center (2006-2014)...

BACKGROUND: Although rheumatic heart disease remains the leading cause of valve heart disease (VHD) in developing countries, other forms of valve disease have been over shadowed and not regarded as a public health problem. However, several facts suggest that the role of non-rheumatic VHD as a significant cardiovascular disease should be reconsidered. We aimed to assess the prevalence and characteristics of different forms of primary left sided valve diseases from a series of 15,009 echocardiographic studies...

The Trifecta aortic valve has excellent hemodynamic performance as result of an expansive valve design with a bovine pericardial sheet externally mounted on a titanium stent. We report two cases of early Trifecta valve degeneration, both caused by partial rupture of one of the leaflet cusps three and four years post-implant. Post discharge, both patients had routinely performed echocardiography check-ups, without signs of valve failure. Transesophageal echocardiography performed while emergency hospital readmission due to severe dyspnea revealed transvalvular aortic regurgitation without signs of endocarditis...

BACKGROUND: Although the Ross procedure offers potential benefits in young adults, technical complexity represents a significant limitation. Therefore, the safety of expanding its use in more complex settings is uncertain. The aim of this study was to compare early outcomes of standard isolated Ross procedures vs expanding elgibility to higher-risk clinical settings. METHODS: From 2011 to 2016, 261 patients (46 ± 12 years) underwent Ross procedures in 2 centres...

Importance: Timing of surgical aortic valve replacement (SAVR) in patients with aortic valve stenosis and previous stroke for the risk of recurrent stroke is insufficiently investigated. Objective: To evaluate the association of time elapsed between previous stroke and SAVR with the risk of recurrent perioperative stroke, major adverse cardiovascular events (MACE), and mortality among patients with aortic valve stenosis. Design, Setting, and Participants: This cohort study using data from Danish administrative registries included all patients with aortic valve stenosis older than 18 years who underwent SAVR between 1996 and 2014 (n = 14 030)...

INTRODUCTION: Isolated aortic valve replacement (AVR) in elderly patients is associated with increased operative risk, due to higher prevalence of associated risk factors and other comorbidities, making outcome prediction essential. In patients with symptomatic severe aortic disease, advanced age is often a reason for a transcatheter rather than surgical aortic valve replacement. In the era of TAVI, there has been renewed interest in the outcomes of conventional AVR for high and intermediate risk patients...

BACKGROUND: Infective endocarditis is a deadly disease if not promptly treated with antibiotics either in association with cardiac surgery or not. Cardiac complications are the most common complications seen in infective endocarditis. Heart failure remains the most common cause of mortality and the most common indication for cardiac surgery in patients with infective endocarditis which is increasingly available in resource limited settings. CASE PRESENTATION: We report a case of native valve infective endocarditis of the aortic valve in a 27-year old female in a semi-urban setting in Cameroon complicated by severe aortic valve regurgitation and heart failure...

OBJECTIVE: Whether the aortopathy associated with bicuspid aortic valve (BAV) disease occurs secondary to genetic or hemodynamic factors remains controversial. In this article we describe the natural history of the aortic root in patients with bicuspid versus tricuspid aortic valves (TAVs) after replacement of the aortic valve and ascending aorta. METHODS: From 1990 to 2010, 406 patients (269 BAV, 137 TAV) underwent aortic valve and ascending aorta replacement at a single institution...

This case describes an unusual presentation of prosthetic valve endocarditis: an acute coronary syndrome. A 67-year-old gentleman presented with cardiac sounding chest pain on a background of a short history of night sweats, weight loss and general malaise. Four months previously he had undergone bio-prosthetic aortic valve replacement for severe aortic stenosis and single vessel bypass grafting of the obtuse marginal. Whilst having chest pain his ECG showed infero-lateral ST depression. Early coronary angiography revealed a new right coronary artery lesion that was not present prior to his cardiac surgery...

BACKGROUND: Limited data are available regarding outcomes for stentless aortic valve reoperation. The reported reoperative mortality has been unacceptably high. METHODS: Between 1997-2017, a retrospective analysis was performed on 143 patients that underwent open aortic valve reoperations for failed stentless aortic valve bioprostheses. We evaluated both short- and long-term outcomes on this cohort of patients. RESULTS: Bicuspid aortic valve was present in 107/143 (75%) of patients at the time of the initial Freestyle procedure and 84% (120/143) patients underwent a modified inclusion aortic root replacement procedure...

MYOCARDIAL INFARCTION IN THE OLD PATIENT: Even old patients may crucially benefit from reopening the occluded coronary artery by percutaneous coronary intervention with stent implantation. Bleeding complications can be reduced by choosing the radial instead of the femoral vascular approach for cardiac catheterization. STATINS FOR THE ELDERLY: WHEN TO START UND WHEN TO STOP?: Elderly benefit no less than the younger from statins. "Goal-oriented statin therapy" is preferable to the "statin strategy of fixed dose"...
