OBJECTIVES Infective endocarditis (IE) is a severe complication in Staphylococcus aureus bacteraemia (SAB) and recent guidelines from the BSAC recommend all patients undergo echocardiography. We assessed the use of echocardiography at a major tertiary referral centre and sought to identify those patients most likely to have positive findings. METHODS We retrospectively evaluated all cases of ...
To the Editor: Pregnant women with mechanical heart valves are an ultrahigh-risk group, in whom all anticoagulant options pose maternal and/or fetal risks. It is unclear why the authors of the recent update1 selected 4 studies, neither the most recent nor of the highest quality, to give a warfarin embryopathy rate of 1.6%. This anomaly rate is not supported by evidence in their Table 1 (3.9% of...
Prosthetic valve thrombosis is a life-threatening complication that is seen most commonly in patients with left-sided prosthetic valves. However, mechanical tricuspid valves carry the highest risk of thrombosis of any cardiac valve. Thrombolysis has been performed successfully in right-sided prosthetic valve thrombosis and has been recommended as the first-line treatment in these patients. Alth...
The assessment of prosthetic valve function remains challenging. Echocardiography has become the key diagnostic tool not only because of its noninvasive nature and wide availability but also because of limitations inherent in alternative diagnostic techniques. Invasive evaluation is limited particularly in mechanical valves that cannot be crossed with a catheter, and in patients with both aorti...
