Infective endocarditis and specific situations: Right heart, valve prosthesis, cardiac implantable electronic device.

[Infective endocarditis and specific situations: Right heart, valve prosthesis, cardiac implantable electronic device]. Presse Med. 2019 May 17;: Authors: Delahaye F, De Gevigney G Abstract Right-sided infective endocarditis (IE) represents 5-10% of IE. It may occur in patients with electronic intracardiac device, central venous catheter or congenital heart disease, but the most frequent situation is intravenous drug use. Prosthetic valve IE is the most severe form of IE. The diagnosis is more challenging than that of native valve IE, as is treatment, both antibiotic treatment and surgical indications. The infection of an electronic intracardiac device is a severe disease. Both diagnostic and therapeutic strategies are difficult. PMID: 31109767 [PubMed - as supplied by publisher]

Conclusions: The mortality rate and the risk of thromboembolic events and endocarditis were similar between BP and MP patients. The risk of bleeding was approximately one third lower for BP patients than for MP patients, while the risk of reoperations was more than three times higher for BP patients.Resumo Fundamento: A escolha de pr óteses mecânicas ou biológicas para pacientes com doença de válvula cardíaca ainda não é um consenso. Objetivo: Determinar os desfechos clínicos de próteses mecânicas e biológicas nesses pacientes. Métodos...

Though heart is known primarily as a pump, it is the four cardiac valves that ensures the critical , non-stop unidirectional flow that sustain the circulation . It is to be recalled these valves originate in the very early days of cardiac development when the primitive heart tube loops , even as the chambers expand from primitive ventricle. Mesenchymal differentiation controlled by various genes that cleaves the valve from myocardial tissue. While heart by itself is the supreme vascular organ ,  its surprising  few structures inside the heart , like the valves are quiet avascular ( or is it really so ?)...

ConclusionAll IE high-risk groups carried a higher risk of IE than the matched controls from the general population. These results justify the European and American guidelines in considering these groups at high risk of IE.

The objectives of this study were to describe and compare the clinical characteristics and outcomes of patients with definite and possible infective endocarditis (IE) involving prosthetic heart valve, and to identify prognostic factors for long-term mortality, using data from an unselected cohort of consecutive patients. We studied data from 133 consecutive patients with IE involving prosthetic heart valve seen in an academic institution between 1990 and 2012. Patients were classified according to the modified Duke criteria for IE: patients with possible IE (n  = 47, 35%) and patients with definite IE (n&thin...

CONCLUSIONS: Despite advanced systemic disease, the surgical treatment of patients with carcinoid heart syndrome is associated with an acceptable perioperative risk and satisfactory mid-term survival. Those patients who survived valve surgery benefited from a significant improvement in their functional capacity. Percutaneous procedures may represent a useful tool to reduce the risk of late valvular reinterventions. PMID: 27989047 [PubMed - in process]

Authors: Hitzeroth J, Beckett N, Ntuli P Abstract Although infective endocarditis (IE) is relatively uncommon, it remains an important clinical entity with a high in-hospital and 1-year mortality. It is most commonly caused by viridans streptococci. Staphylococcus aureus is responsible for a malignant course of IE and often requires early surgery to eradicate. Other rarer causes are various bacilli, including the HACEK (Haemophilus, Actinobacillus,Cardiobacterium, Eikenella and Kingella spp.) group of organisms and fungi. The clinical presentation varies. Patients may present with a nonspecific illness, valve dysfu...

The post below first appeared on HuffPost Healthy Living on April 20. Jen Hyde, a 30-year-old poet and artist living in Brooklyn, has a congenital heart defect. By the age of 25, Hyde had two open-heart surgeries, including a heart valve replacement. “I know that heart disease is the number one killer of women in America,” Hyde said. “I’m currently in great shape, but part of staying this way means building a strong relationship with my cardiologist so that the care I receive is preventative, not reactive.” Hyde is not alone in suffering from heart health issues — in the U.S., cardiova...

We present a case of a 50-year-old man with advanced liver cirrhosis and native valve infective endocarditis caused by methicillin-resistant Staphylococcus epidermidis. Bacterial infections are one of the most common complications of liver cirrhosis, but reports of infective endocarditis in patients with liver cirrhosis are relatively rare. Because of vulnerability of patients with advanced cirrhosis for developing infections, it is necessary to pay attention to the pathogens that are sometimes considered contamination and actively seek for the seat of infection, even in less expected areas (e.g., native heart valves witho...

Purpose of review: In recent years, great emphasis has been placed on reconstructive techniques for the surgical management of heart valve disease. In this review, we discuss recent data and current practice as it pertains to the subject of reconstructive valve surgery. Recent findings: New techniques and an improved understanding of the mechanisms of aortic insufficiency have led to marked improvement in the early and late outcomes of aortic valve repair. While mitral valve repair is the established approach for the management of degenerative mitral valve disease, surgical technique continues to be refined, with valve re...

Infective endocarditis (IE) often poses challenges of the diagnostic and/or treatment variety. Take, for instance, the case of a 24-year-old man with congenital heart disease who is diagnosed with Bartonella henselae IE. Patient: “What’s the next step, doc?” Physician: “You will have a peripherally inserted central catheter in your arm through which you will receive intravenous antibiotics for 6 weeks. This will be followed by at least 3 to 6 months of oral antibiotics, potentially longer. These antibiotics may cause diarrhea. You will need to have your pacemaker removed and then replaced. If your h...
