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.

Carotid artery stenosis in asymptomatic patients undergoing coronary artery bypass grafting: who and when should be screened?

BACKGROUND: Carotid artery stenosis (CAS) is one of the major causes of stroke in coronary artery bypass grafting (CABG). AIMS: The aim of this study was to determine which age groups require screening for CAS using carotid duplex ultrasound in asymptomatic patients undergoing CABG. METHODS: We included 644 neurologically asymptomatic consecutive patients (mean [SD] age, 63.9 [8.8] years; men, 453 [70.3%]) who underwent elective isolated CABG between June 2015 and June 2020. Clinical, demographic, and radiological data as well as coronary angiography results were retrospectively reviewed. Patients were classified into 4 age groups: 40 to 50, 51 to 60, 61 to 70, and >70 years, as well as 3 groups depending on the CAS degree: 50% or less, 50% to 70%, and 70% or greater. Regression analysis was applied across the selected parameters to identify risk factors for significant CAS, and receiver operating characteristic analysis, to determine cutoff age and SYNTAX score of patients who had to be screened before CABG. RESULTS: Overall, 8 (1.1%) patients included in the present study had stroke following CABG. Cutoff values of the SYNTAX score and CAS of 70% or greater were found to be 27 and 64 years, respectively. The sensitivity and specificity of the cutoff value were 98.4% to 98.3% and 74.3% to 55.1%, respectively. The area under the curve was 0.98 and 0.73, respectively. CONCLUSION: Based on the receiver operating characteristic analysis, we recommended to perform screening for CAS in patients older than 64 years and with a SYNTAX score of 27 or higher, even if they are asymptomatic.

Internal Jugular Vein Catheterization: The Landmark Technique versus Ultrasonography Guidance in Cardiac Surgery.

Background Central venous catheterization is an invasive procedure that must be performed during cardiovascular surgery. The addition of ultrasound guidance to the catheterization technique has shown effectiveness in reducing complications because it allows for the visualization of anatomical variations prior to intervention and the continual visualization of the needle during the placement. The purpose of this study was to evaluate the effectiveness of needle-guiding ultrasound for internal jugular venous cannulation. Method Patients undergoing coronary bypass surgery at Hitit University, department of cardiovascular surgery, from January 2014 to June 2018, were included in the study. The patients were divided into two groups: those with catheterization with ultrasound guidance (Group U) and those with catheterization performed with the anatomic landmark technique (Group L). Results A total of 584 cases were investigated. The success of the procedure and complication rates for both methods were compared. Central vein catheterization with ultrasonography produced success and complication rates significantly better than those for catheterization using the landmark technique (p=0.04 and p=0.00001, respectively). Conclusion This study demonstrated that the use of ultrasonography for internal jugular vein catheterization for patients undergoing coronary bypass surgery significantly reduced the complication rates as compared to those of patients where the landmark technique was used for catheterization.
