The Combined Konno-Nicks Procedure for Severely Stenotic Aortic Root and Left Ventricular Outflow Tract

Key Points

Generally, the combined procedure enhances outflow tract dynamics and reduces right ventricular pressure after surgery.
A significant increase in cardiac output was observed, with measurements indicating improved hemodynamics post-operation.

Structured PICO

Does the combined Konno-Nicks procedure effectively relieve prosthetic valve dysfunction in patients with severe subvalvular stenosis?

Population

Patients with severely stenotic aortic root and left ventricular outflow tract, including those with prosthetic valve dysfunction and severe subvalvular stenosis

Intervention

Combined Konno-Nicks procedure

Outcome

Relief of prosthetic valve dysfunction and enabling larger prosthesis implantation

The combined Konno-Nicks procedure is an effective surgical strategy for addressing severe subvalvular stenosis and prosthetic valve dysfunction by allowing for a larger prosthesis.

Abstract

The combined Konno-Nicks procedure can effectively relieve prosthetic valve dysfunction with severe subvalvular stenosis by enabling larger prosthesis implantation.
