Aortic Root Enlargement

Aortic valve replacement is a gold standard in the treatment of patients with severe aortic stenosis or combined aortic pathology. However, aortic valve pathology is often associated with a narrow aortic orifice, particularly in patients with severe aortic stenosis. In 1978, Rahimtoola first described the term of prosthesis-patient mismatch. He noted that effective orifice area of the prosthesis is smaller than that of the native valve. To minimize this complication, there are several surgical strategies: aortic root enlargement (ARE), implantation of a frameless biological prosthesis in the native position, neocuspidalization procedure, Ross procedure, aortic root replacement with xenograft or homograft. ARE is an excellent option, however, some authors outline additional perioperative risks. The aim. To analyze immediate results of ARE during isolated aortic valve replacement and in cases when it is combined with other heart pathologies. Materials and methods. Our study included 63 patients who underwent ARE. Isolated aortic valve replacement was performed in the majority of cases, but often aortic root replacement procedure was combined with coronary artery bypass grafting. Results and discussion. One of 63 patients died (hospital mortality 1.6%) at an early hospital stage (30 postoperative days). Measurement of the aortic valve ring was performed by two methods, through preoperative echocardiography and perioperative measurement using a valve sizer. However, perioperative dimension was chosen as the basis for the calculations. In 62 patients, the perioperative diameter of the aortic valve ring ranged from 19 to 23 mm, only one patient had a diameter of 24 mm. According to our findings, ARE enabled to achieve an average aortic ring size increase of 2.68 cm2 (from 1.5 to 3.4 cm2) and to prevent prosthesis-patient mismatch in 42 (66.7%) cases. Conclusions. Prosthesis-patient mismatch is considered a serious complication in the postoperative period. Narrow aortic root is a common pathology that should be considered during surgery. ARE is a safe procedure and is not associated with an increased risk of mortality and complications.

Valve Detachment

<p><b>Background:</b> Prosthetic valve detachment after aortic valve replacement and pseudoaneurysm formation are the most important postoperative complications in patients with Takayasu arteritis with aortic regurgitation. We reviewed our experience of surgical treatment of aortic regurgitation in patients with Takayasu disease.</p><p>Methods: Between November 1997 and September 2011, 11 patients (4 women and 7 men) with Takayasu arteritis with aortic regurgitation underwent surgical treatment. The age of the patients ranged from 26 to 56 years (mean, 40 � 9 years). Primary isolated aortic valve replacement was performed in 1 patient, David procedure in 1 patient, Wheat procedure in 1 patient, Bentall procedure in 2 patients, and Cabrol procedure in 6 patients (including 2 patients who underwent primary aortic valve replacement in other hospitals before being admitted to our surgical team).</p><p><b>Results:</b> There was no in-hospital death. All patients had an uneventful recovery during the postoperative course and were discharged. Prosthetic valve detachment, pseudoaneurysm formation at the suture line, and dilatation of the ascending aorta were not found in patients with composite aortic root replacement during a mean follow-up of 98 � 45 months. One patient died during follow-up.</p><p><b>Conclusion:</b> Valve detachment after composite aortic root replacement was not observed in patients with Takayasu disease with aortic regurgitation. Satisfactory surgical outcomes were obtained using composite aortic root replacement. However, close follow-up was needed to assess the effectiveness of the Cabrol procedure in patients with Takayasu disease with aortic regurgitation.</p>

Background: Since 1968, ascending aorta replacement with a valved conduit has been the standard practice for aortic root aneurysm. By the end of the 20th century, aortic valve sparing operation emerged and evolved as an alternative to aortic valve replacement. Objective: The aim of this study was to report our experience with aortic valve sparing technique and its long -term outcomes. Methods: A total of 116 consecutive cases with criteria of repairability operated on between 2005 and 2019 were analyzed. Preopera- tive transesophageal echocardiography (TEE) and computed tomography angiography (CTA) were used in combination to determine the aortic phenotype based on a previous anatomical and functional classification. Perioperative control was performed and conver- sion to aortic valve replacement was left to the discretion of the attending surgeon. Intraoperative variables, in-hospital morbidity and mortality, freedom from significant aortic regurgitation (AR) and reoperation in the clinical and echocardiographic follow-up were reported. Results: Mean age was 56±15.6 years and 73% were men; 59% were asymptomatic, and the reason for the intervention was the aortic diameter (52±11.7 mm) or progression of AR. After the procedure, 4% of the cases presented mild or trivial AR and 2 patients required conversion to aortic valve replacement (1.7%). In hospital mortality was 0.9%. Actuarial survival was 88% at 10 years, and 79% were free from significant (moderate/severe) AR. Five cases underwent reoperation after a mean interval of 9.1 years and free- dom from reoperation at 10 years was 90%. There were no major thromboembolic or bleeding events. Conclusion: Aortic valve sparing technique in the setting of aortic root disease is a feasible and safe option, and stable over time
