LEFT VENTRICULAR OUTFLOW TRACT RECONSTRUCTION FOR ANNULAR EROSION Sotiris Stamou, MD, Michael Murphy, MD and Nicholas T. Kouchoukos, MD Division of Thoracic and Cardiovascular Surgery Missouri Baptist Medical Center
Indications • When destruction or distortion of the annulus precludes safe placement of prosthetic valve • When insertion of a prosthesis would result in LVOT or coronary obstruction
Methods • N=10 • 6 males • Median age: 49 • Range: 26 to 61 years • Indications:Endocarditis (3) calcification of aortic root (1) pseudoaneurysm (2) obstruction of aortic valve prosthesis (1) degeneration of allograft (3)
Methods • Previous operation: • Aortic root allograft (5) • Composite Graft aortic root replacement (3) • Aortic valve replacement (n=1)
Results • All patients survived the operation • Two late deaths from renal failure and cardiac failure • 8 Patients alive 1 to 84 months postoperatively
Conclusion • LVOT reconstruction and translocation of the aortic valve for annular erosion is a useful technique that eliminates bleeding from the annular suture line, LVOT obstruction and can be safely performed with satisfactory outcomes
