In the period 1977 to 1997, the Double Valve Surgery or (DVR) double valve replacement was conducted on around 316 patients. This estimation of the figures is achieved with thorough assessment of the medical accounts of those sufferers. The numerical data assessment of long-period survival was detected through the Kaplan-Meier technique. The outline of the Cox failure was utilized to estimate prospective analysis of the death rates.  In the path of this double valve replacement treatment review, it was shockingly observed that nearly 5.4%, which means around 17 cases were of premature death rate and around 96 cases were of delayed death rate. A minimum lifespan of 15 years, at an average rate of 44% was assessed for the patients undergone the double valve surgery. A count of six cases of periprosthetic trickles in the double valve replacement was evaluated. Pre-surgical aortic and mitral valves pathology or former cardiac surgical treatment, and gender factor have not shown any crucial impact over this double valve replacement results. In most of the cases, the mitral valve seems to be confident of endurance, subsequent to the double valve surgery and it needs to be noted that endurance is not critically inclined towards the restoration of the damaged mitral valves.

The Debate:

The substitution of the aortic valve during a double valve surgery is not considered as controversial.  Although, the virtual qualities of both the refurbishing of the mitral valve or substitution of the mitral valve in all those patients needs to be apparently classified.  Usually, there are three kinds of substitution valves used during a double valve surgery.  One type is created from certain tissues of animals, typically from the aortic valves of the pig.  The other is a quite artificial and technical innovative created from plastic and metal. The third one is of the human valves that have been eradicated from certain organ donor. No lone standardized substitution of the valve is accessible and hence, the selection of the valves of animal or a mechanical valve greatly depends on the age of the patient, who is scheduled to undergo a double valve surgery. But usually, the mechanical valves are implanted in younger patients due to their toughness, whereas the animal valves are mostly implanted in the elder patients due to their long lifespan of around 7-15 years.  The double valve surgery with the pulmonary or donor’s valves is performed on the patients, who are likely get worsened quickly due to the contraction of the vessels amid the left ventricle and the aorta. 

Confirmations:

The pulmonic or donor’s valves are implanted to such patients via double valve surgery, because they are restricted in their utilization due to the little contribution accessible from the donors and the damage that may root from, by the elimination and transmission of the pulmonic valves of the patient himself. A patient scheduled to undergo double valve surgery is required to perform several tests completely, prior to going under the knife.  These tests are very essential in the detection of any indications for the patient’s ability of bearing the surgical procedure. A preoperative test of electrocardiography is quite necessary to perform.
