Redo aortic valve replacement after partial upper sternotomy (hemisternotomy) in a patient with idiopathic thrombocytopenia: a case report

BACKGROUND: We present a case of redo aortic valve replacement in a patient with thrombocytopenia. The initial operation was performed through limited access transverse sternotomy. This is the first report of this kind in the literature. CASE PRESENTATION: A 62 year old Caucasian male farmer with thrombocytopenia had uneventful redo aortic valve replacement when the first xenograft failed after 9 years, the transverse upper hemisternotomy in the first operation appearing to facilitate the redo complete sternotomy. CONCLUSION: With this only case of redo aortic valve replacement in our practice of 90 hemisternotomies over 10 years we present for consideration the use of a tissue valve in a complex relatively young patient

Evolving dimensions in medical case reporting

Medical case reports (MCRs) have been undervalued in the literature to date. It seems that while case series emphasize what is probable, case reports describe what is possible and what can go wrong. MCRs transfer medical knowledge and act as educational tools. We outline evolving aspects of the MCR in current practice

Combined sterno-clavicular approach as an alternative technique in hybrid exclusion of aortic arch aneurysm

<p>Abstract</p> <p>Background</p> <p>We describe a modified access technique for the proximal (open) part of single stage hybrid exclusion of aneurysm of the aortic arch.</p> <p>Case presentation</p> <p>3 patients had a bifurcated Dacron graft for the innominate and left subclavian arteries and an additional end-to-side anastomosis of the left common carotid artery on the limb to the left subclavian artery. With our modification, access to the left subclavian artery is by left subclavicular incision and creation of an anterior tunnel via the left thoracic outlet from the origin of the left subclavian artery along its anatomical course to the subclavicular plane.</p> <p>Discussion</p> <p>Advantages and disadvantages of this technique in relation to anatomy and pathology.</p

Contegra conduit for reconstruction of the right ventricular outflow tract: a review of published early and mid-time results

<p>Abstract</p> <p>Objective</p> <p>The valved conduit Contegra (bovine jugular vein) has being implanted for more than 7 years in the right ventricular outflow tract and it is noted that the available reports have been mixed. The aim of this study is to review the reported evidence in the literature.</p> <p>Methods</p> <p>Search of the relevant literature for the primary endpoints of operative mortality and morbidity and secondary endpoints of follow-up haemodynamic performance including severe stenosis, regurgitation and need for reintervention are presented.</p> <p>Results</p> <p>We selected and analysed 17 series including 767 patients. Commonest indication was Fallot's tetralogy. Operative mortality was 2.6%. Operative morbidity was 13.9%. In follow-up, the incidence of intraconduit stenosis was 10.9% (incidence of stenosis for the 12 millimetre conduit was 83.3% in one series) and that of at least moderate regurgitation was 6.3%.</p> <p>The aspirin users had a stenosis incidence of 10.5% compared to the non-users had a stenosis incidence of 9.6%.</p> <p>Conclusion</p> <p>A dissent on the performance of the Contegra is discussed, while results are satisfactory in the majority of studies apart for the smallest conduits (12 and 14 millimetre), suggesting an association to compromised run-off. The role of aspirin as antithrombotic modulator remains controversial.</p
