Aortic Valve Sparing Techniques: Our Experience With Tirone David Procedure
Part of Topic
Valve – Surgical Valves
Aortic root surgery still represents a complex challenge for cardiac surgeons. Over the years, several techniques havebeen developed, leading to the refinement of aortic valve-sparing procedures, among which the Tirone David procedure, firstly introduced in 1992, and its subsequent modifications, are the most widespread and commonly usednowadays. In our center, aortic valve reimplantation using a straight tube graft (David I) represents the aortic valve-sparingtechnique of choice, commonly used in aortic root dilatation associated with aortic valve insufficiency.This study aims to report the data collected from 2017 in the Careggi’s cardiac surgery unit regarding the effectiveness of the modified Tirone David procedure in terms of mortality, freedom from disease, and freedom from reoperation, including specific patient groups such as those with Marfan syndrome and bicuspid aortic valve patientsThis study represents a first step for a deeper evaluation of possible preoperative charateristics of early failure basedon CT scan analysis.Our study demonstrates that the modified Tirone David technique is associated with low short-term and long-term mortalityrates and a low rate of reintervention.Our study demonstrates that aortic valve reimplantation represents a valid surgical alternative for treating acute aorticdiseases, such as aortic dissection.During the follow-up, patients who underwent this type of surgery exhibited a high freedom from moderate or severe aorticinsufficiency (AI). These results were also observed in particular patient categories (such as those with Marfan syndrome and BAV).In our study there were no significant differences in short and long-term results between median sternotomy or MICS. In conclusion, the Tirone David technique should be considered the primary surgical choice for patients with aortic root pathology and anatomically normal valve cusps, even in the presence of congenital diseases or in emergency settings in experienced centers
