An open aortic valvuloplasty is a surgical procedure aimed at correcting a narrowed or stenosed aortic valve, which is a critical component of the heart's function. The aortic valve typically consists of three leaflets or cusps that open and close to regulate blood flow from the heart into the aorta. When this valve becomes narrowed, it can impede blood flow, leading to various cardiovascular complications. This procedure is performed using cardiopulmonary bypass, which temporarily takes over the function of the heart and lungs, allowing the surgeon to operate on a still and bloodless field. Alternatively, inflow occlusion may be employed, which involves temporarily blocking blood flow to the heart to facilitate the surgery. Access to the heart is achieved through a median sternotomy, where the sternum is opened, or through a thoracotomy, which involves an incision in the chest wall. The procedure involves cross-clamping and incising the aorta to access the valve, followed by dilation of the valve or division of any scar tissue present. After the procedure, the aorta is closed, and normal blood flow is restored, concluding the surgical intervention.

The open aortic valvuloplasty procedure is indicated for patients experiencing aortic valve stenosis, which is characterized by the narrowing of the aortic valve opening. This condition can lead to significant cardiovascular issues, including heart failure, chest pain, and syncope. Additionally, the procedure may be indicated for patients with aortic valves that are malformed, having only one or two cusps instead of the normal three, which can also result in impaired blood flow and increased cardiac workload.
The open aortic valvuloplasty procedure involves several critical steps to ensure successful intervention on the aortic valve. First, the patient is placed under general anesthesia to ensure comfort and immobility during the surgery. Access to the heart is achieved through a median sternotomy, where the sternum is carefully divided to provide a clear view of the heart. In cases where cardiopulmonary bypass is utilized, the aorta is cannulated, and the superior and inferior vena cava are also cannulated to divert blood flow away from the heart. This allows the heart to be effectively isolated from the circulation. Alternatively, if inflow occlusion is chosen, snares are used to occlude the superior and inferior vena cava, allowing the heart to empty of blood temporarily. Once the heart is adequately prepared, the aorta is cross-clamped and incised to access the aortic valve. The surgeon then proceeds to dilate the valve or divide any scar tissue that may be present, which is crucial for restoring normal function. After the necessary adjustments to the valve are made, the incision in the aorta is closed, and the cardiopulmonary bypass or inflow occlusion is terminated. Finally, the surgical incisions are closed, and chest tubes may be placed as needed to facilitate drainage and prevent fluid accumulation.
After the open aortic valvuloplasty procedure, patients are typically monitored in a recovery area for any immediate complications. The expected recovery period may vary depending on the individual patient's health status and the complexity of the surgery. Patients may experience some pain and discomfort at the incision sites, which can be managed with appropriate pain relief medications. It is common for chest tubes to be placed to drain any excess fluid or blood that may accumulate in the chest cavity. Patients will be closely monitored for signs of infection, bleeding, or other complications. Cardiac rehabilitation may be recommended as part of the recovery process to help patients regain strength and improve cardiovascular health. Follow-up appointments will be necessary to assess the function of the aortic valve and overall heart health.
