Outcomes of Surgery of Aortic Valve
Outcomes of Surgery of Aortic Valve
Overall Goal: To study the outcomes of patients undergoing aortic valve surgeries, different
 approaches such as standard aortic valve replacement, aortic valve repair, novel techniques
 as Ozaki's procedure and their subsequent results and complications.

 -  Objective 1: Identify predictors of complications following different types of aortic
 valve surgery accordingly.

 -  Objective 2: Determine the value of each type in terms of advantages and disadvantages.

 -  Objective3: Assess outcomes such as postoperative life expectancy, hospital stay,
 prognosis and quality of life.
Inclusion Criteria:

 1. Patients with severe symptomatic aortic valve lesion.

 2. Asymptomatic aortic insufficiency patients with left ventricular dysfunction or
 significant left ventricular dilatation (LV end diastolic diameter>70 mm or LV end
 systolic diameter>50 mm.

 3. Patients with aortic regurgitation caused by:

 -  a dilated aortic annulus

 -  conjoined cusp prolapse in bicuspid aortic valves (BAV)

 -  single cusp prolapse in tricuspid aortic valves

 -  aortic valve cusp perforation from endocarditis

 Exclusion Criteria:

 -  Patients with previous aortic root or valve surgery.
