Abstract :

<p class="MsoNormal" style="text-align:justify;line-height:200%">When a patient needs a valve replacement today, there are several options for the valve substitute. The most often used mechanical valve prosthesis is <b style="mso-bidi-font-weight:normal">&ldquo;Bileaflet&rdquo;</b> or &ldquo;<b style="mso-bidi-font-weight:&#10;normal">Tilting disc</b>&rsquo;&rsquo;.<span style="mso-spacerun:yes">&nbsp; </span>To determine which is the best valve prosthesis³ for a particular patient, we have to look at the results of different kind of valve substitutes in large mainly retrospective series. In our centrearound 60% of all open heart procedures per annum are valve replacements of which 20% are isolated aortic valve replacementdone using mechanical valve prosthesis either <b style="mso-bidi-font-weight:normal">&ldquo;bileaflet&rdquo; </b>or &ldquo;<b style="mso-bidi-font-weight:&#10;normal">tilting disc</b>&rsquo;&rsquo; from different marketing companies. <span style="mso-spacerun:yes">&nbsp;</span>This study designed retrospectively to analyse<span style="mso-bidi-font-weight:bold">ease of procedure on valve orientation and placement, immediate post-operative hemodynamics ,post op left ventricular function,<span style="mso-spacerun:yes">&nbsp;&nbsp; </span>gradient across the valve, incidence of valve thrombosis, Embolic and hemorrhagic complications, valve related mortality, freedom from complications for 6 months after discharge and </span>in a group of 150 patients operated in our hospital.</p>
