The Konno-Rastan procedure.

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Congenital Heart Disease

Background:

• Aortic stenosis presents a significant challenge in cardiac surgery, requiring effective interventions for subvalvar, valvar, and supravalvar obstructions.
• Patients with prior aortic and/or mitral prostheses often have complex anatomies, necessitating specialized surgical approaches.
• Rheumatic heart disease can lead to severe aortic valve disease and necessitate complex reconstructive procedures.

Observation:

• This video tutorial details the Konno-Rastan procedure, an anterior aortoventriculoplasty.
• The case involves a patient with a history of rheumatic heart disease and prior mechanical aortic and mitral prostheses.
• The procedure focuses on relieving stenosis at multiple levels within the aortic outflow tract.

Findings:

• The Konno-Rastan procedure effectively addresses complex aortic stenosis, including cases with prosthetic valves.
• Safe execution of the Konno incision is demonstrated, crucial for accessing the subaortic region.
• Successful reconstruction of the aortic root, ventricular septum, and right ventricular outflow tract using bovine pericardium is shown.

Implications:

• The Konno-Rastan procedure provides a viable surgical option for complex aortic stenosis, particularly in patients with prosthetic valves.
• Detailed procedural insights enhance the understanding and safe application of this advanced cardiac surgery technique.
• This approach may improve long-term outcomes for patients with challenging aortic stenosis and prior valve replacements.
