| ==Overview==
| |
| Surgical intervention may be a necessary component of treatment. Intervention methods may include utilizing various techniques of aortic valvuloplasty.
| |
|
| |
| ==Aortic valvuloplasty==
| |
| ===Patient selection and treatment choices===
| |
| * Surgical Aortic valve replacement is the treatment of choice for aortic stenosis but many patients are not good candidates due to advanced age and multiple co-morbidities
| |
| * Percutaneous aortic valve replacement is in its infancy and thus aortic valvuloplasty can offer palliation of symptoms and potentially prolong survival for these high risk patients in class III-IV heart failure
| |
| * It can be performed emergently in patients with end-stage heart failure due to aortic stenosis: patients in cardiogenic shock, as a bridge to aortic valve replacement, patients with critical aortic stenosis needing emergent non-cardiac surgery, poor surgical candidates and nonagenerians, patients with congenital or rheumatic aortic stenosis
| |
| * Results usually last 6 months up to 2 years (with repeat procedures possible if aortic regurgitation is not severe)
| |
| * Valvuloplasty tends to alleviate heart failure symptoms and improve hemodynamics but rarely does it alleviate angina
| |
|
| |
| ====Technique====
| |
| The retrograde technique is the most commonly used technique.
| |
| *8 French femoral sheath can usually accommodate a 20 mm balloon and minimizes vascular complications
| |
| *Alternatively two 6 Fr sheath from bilateral femoral approach and two smaller balloons can be used
| |
| *The letter may be necessary in female elderly patients with concomitant peripheral vascular disease
| |
| *0.035” straight wire is commonly used to cross the valve and advance via pig-tail or Amplatz catheter; Right heart catheterization is done and transaortic gradient is typically measured pre-procedure
| |
| *The 0.035” wire is then exchanged for a stiffer 0.038”Amplatz exchange length wire with the tip shaped into a pig-tail shape so as not to injure the LV
| |
| *The 20-23 mmX 6 cm balloon is advance over the wire and positioned to straddle the aortic valve
| |
| *The balloon is manually inflated with a 60 cc syringe containing diluted contrast (slowly)
| |
| *Meticulous control of balloon position must be maintained at all times by backward traction on the balloon to prevent jumping forward and injuring/perforating the LV apex
