Tricuspid repair: short and long-term results of suture annuloplasty techniques and rigid and flexible ring annuloplasty techniques.

BACKGROUND: Functional tricuspid regurgitation may arise from left heart valve diseases or other factors. If not addressed concurrently with primary surgical intervention, it may contribute to increased morbidity and mortality rates during the postoperative period. This study investigates the impact of various repair techniques on crucial factors such as systolic pulmonary artery pressure (SPAP), tricuspid valve regurgitation, and New York Heart Association (NYHA) functional capacity class in the postoperative period. MATERIALS AND METHODS: From April 2007 to June 2013, 379 adults underwent open-heart surgery for functional tricuspid regurgitation. Patients were categorized into four groups: Group 1 (156) with De Vega suture annuloplasty, Group 2 (60) with Kay suture annuloplasty, Group 3 (122) with Flexible Duran ring annuloplasty, and Group 4 (41) with Semi-Rigid Carpentier-Edwards ring annuloplasty. Demographic, clinical, operative, and postoperative data were recorded over a mean follow-up of 35.6 ± 19.1 months. Postoperative SPAP values, tricuspid regurgitation grades, and NYHA functional capacity classes were compared among the groups. RESULTS: No statistically significant differences were observed among the groups regarding age, gender, preoperative disease diagnoses, history of previous cardiac operations, or echocardiographic characteristics such as preoperative ejection fraction, SPAP, and tricuspid regurgitation. Hospital and intensive care unit length of stay and postoperative complications also showed no significant differences. However, patients in Group 3 exhibited longer Cardio-Pulmonary Bypass duration, cross-clamp duration, and higher positive inotrope requirements. While the mortality rate within the first 30 days was higher in Group 1 compared to the other groups (p: 0.011), overall mortality rates did not significantly differ among the groups. Significant regression in functional tricuspid regurgitation and a notable decrease in SPAP values were observed in patients from Group 3 and Group 4 (p: 0.001). Additionally, patients in Group 3 and Group 4 showed a more significant reduction in NYHA functional capacity classification during the postoperative period (p: 0.001). CONCLUSION: Among the repair techniques, ring annuloplasty demonstrated superiority in reducing SPAP, regressing tricuspid regurgitation, and improving NYHA functional capacity in functional tricuspid regurgitation repairs.

Outcomes of Planned Marginal and Wide Resection of Sarcomas Associated with Major Vascular Structures in Extremities.

Bone and soft tissue sarcomas of lower and upper extremities may sometimes be in close contact with neurovascular structures. In such cases, it is controversial that whether en bloc resection and vascular reconstruction to reach wider surgical margins or planned marginal resection with the help of adjuvant therapies should be preferred. This study aimed to determine surgical and oncological outcomes of planned marginal and wide resection of extremity sarcomas that are associated with major vascular structures in the extremities. The collected database of 54 patients treated by the same orthopedic and vascular surgeon for primary or locally recurrent soft and bone tissue sarcoma of extremities was retrospectively reviewed. Eligible subjects for this study were patients diagnosed with upper and lower extremity soft and bone tissue sarcomas that encased a maximum of 50% of the circumference of the major vascular structures, requiring limb-sparing resection. When microscopic positive (19 patients, 33.9%) and negative cases' (35 patients, 66.1%) surgical margins were compared, local recurrence, metastasis, amputation, and tumor type (soft/bone) parameters showed no statistically significant difference. When metastatic and non-metastatic patients were compared, it was shown that bone tumors metastasized more than soft tissue tumors (p = 0.001). However, there was no difference between metastasis and amputation, histopathology, grade, nerve involvement, surgical margins, or local recurrences. The mean survival was 1460.6 ± 137.4 days, and the 6-year mortality was 87.5%. Anesthetic and surgical complication rates may be higher since en bloc resection surgeries of large tumors with vascular reconstructions take a very long time. Therefore, we suggest marginal resection with sub-adventitial dissection in those locations and wide resection at other areas according to the surgeon's experiences about safe margin with the contribution of radiotherapy.
