Homograft implantation in the aortic position was a common approach for full root aortic surgical procedures in the early 2000s. Reintervention after degeneration of such homografts remains a challenge. We report two cases of successful implantation of the Edwards Intuity Elite rapid deployment valve into patients with degeneration of existing aortic homograft implants leading to severe aortic regurgitation.

A recent case led the authors to re-examine the clinical characteristics of the cervical ectopia of the major salivary glands. These glands develop in the embryo between the sixth and seventh week, starting with the formation of endodermal invaginations of the branchial section of the floor of the primitive mouth. These cell cords, initially solid, proliferate in the underlying mesenchyme, starting from the opening of the future excretory duct, and subsequently branch and canalize.

Objective: Mitral valve repair with artificial chordae for degenerative mitral regurgitation is widely adopted. We evaluated long-term results of mitral repair with expanded polytetrafluoroethylene sutures (GORE-TEX CV-5; W. L.

Article Synopsis
  • The study analyzed 15-year outcomes for 1,274 patients who received either aortic or mitral valve replacements using the Hancock II bioprosthesis across hospitals in the Venetian area.
  • The overall 15-year survival rate was 39.7%, with survival influenced by factors such as gender, heart function class, and presence of coronary artery disease; aortic valve replacements had better outcomes for embolism and reoperation rates.
  • Patients over 60 years showed a 96.5% freedom from structural valve deterioration after aortic valve replacement compared to 88% for mitral, indicating better longevity of aortic implants, especially in older patients.

Objective: We performed a multi-institutional study to compare the long-term structural valve deterioration of isolated Hancock Standard versus Hancock II bioprostheses.

Methods: From 1983 to 2002, 714 Hancock Standard and 1293 Hancock II bioprostheses were implanted at hospitals of the Venetian territory (Padova, Treviso, and Venice). Follow-up on January 1, 2003, included 14,749 patient-years with a median of 12 years and was 96% complete: 115 Hancock Standard and 53 Hancock II bioprostheses were at risk at 15 years.
