RESUMEN
Background: This study aimed to compare the outcomes of minimally invasive mitral valve surgery and conventional surgery in terms of mortality and postoperative complications. Methods: A retrospective analysis was conducted on consecutive minimally invasive and conventional mitral valve surgeries performed between January 2019 and December 2022. Patients undergoing concomitant procedures were excluded from the study, and 293 patients (149 females, 144 males; mean age: 53.8±12.9 years; range, 18 to 82 years) were included in the study. Of these patients, 96 underwent minimally invasive surgery (MI group), and 197 underwent mitral valve surgery via conventional sternotomy (CS group). Propensity score matching was utilized to minimize the biases and confounding factors. After propensity score matching, 55 patients were included in each group. Results: There was no statistically significant difference in terms of mortality between the propensity score-matched groups (p=0.315), and no statistically significant difference in postoperative complications was observed between the groups. However, it was found that postoperative new-onset atrial fibrillation was lower in the minimally invasive group (p=0.022). Conclusion: This study demonstrates that minimally invasive mitral valve surgery is a safe alternative with similar mortality and postoperative complication rates compared to conventional surgery. Additionally, the study suggests an association between minimally invasive surgery and postoperative new onset atrial fibrillation.
RESUMEN
INTRODUCTION: The aim of this study is to compare the postoperative outcomes and early mortality of peripheral and central cannulation techniques in cardiac reoperations using propensity score matching analysis. METHODS: In this retrospective cohort, patients who underwent cardiac reoperations with median resternotomy were analyzed in terms of propensity score matching. Between November 2010 and September 2020, 257 patients underwent cardiac reoperations via central (Group 1) or peripheral (Group 2) cannulation. A 1:1 propensity score matching was performed to balance the influence of potential confounding factors to compare postoperative data and mortality rate. RESULTS: There were no significant differences when comparing the matched groups regarding early mortality (P=0.51), major cardiac injury (P=0.99), prolonged ventilation (P=0.16), and postoperative stroke (P=0.99). The development of acute renal failure (P=0.02) was statistically less frequent in Group 1. CONCLUSIONS: Performing cardiopulmonary bypass via peripheral cannulation increases acute renal failure in cardiac reoperations. In contrast, peripheral or central cannulation have similar early mortality rate in cardiac reoperations.

OBJECTIVE: Atrial ï¬brillation is the most common arrhythmia following coronary artery bypass graft surgery. The relationship between impaired lung function and atrial ï¬brillation has been described previously. We aimed to evaluate the prognostic inï¬uence of small airway function on predicting postoperative atrial ï¬brillation undergoing isolated coronary artery bypass graft surgery (CABG). METHODS: We retrospectively analyzed 283 patients who underwent isolated CABG at our institution between January 2020 and August 2020. The patients were divided into 2 groups according to the development of postoperative atrial ï¬brillation. Demographic characteristics of the patients were recorded; spirometry was performed for each patient before surgery. Small airway function was determined by forced mid-expiratory ï¬ow (forced expiratory ï¬ow 25%-75%) values measured by spirometry. Propensity score matching was applied to ensure a balanced distribution of demographic data between the 2 groups. RESULTS: The frequency of postoperative atrial ï¬brillation was 30.7% in our patient population. After propensity matching, forced expiratory volume in 1 second/forced vital capacity % [80.6 (73.8-87.8) vs. 76.3 (66.7-81.6), P = 0.006] and forced expiratory ï¬ow 25%-75% (87.4 ± 14.2 vs. 75.2 ± 15.8, P = 0.001) were signiï¬cantly lower in postoperative atrial ï¬brillation group. In multivariate analysis, white blood cell count, left ventricular ejection fraction, cross-clamp time, and forced expiratory ï¬ow 25%-75% were found to be independent predictors of postoperative atrial ï¬brillation development after isolated CABG. In the receiver operating characteristic curve analysis, forced expiratory ï¬ow 25%-75% with an optimal threshold value of 81% could detect the presence of postoperative atrial ï¬brillation with 63.8% sensitivity and 70.1% speciï¬city. CONCLUSION: Our study demonstrated that small airway obstruction, as indicated by forced expiratory ï¬ow 25%-75% in spirometry, can be a simple predictive tool for the development of postoperative atrial ï¬brillation in patients undergoing isolated CABG.

OBJECTIVE: Pannus overgrowth is a chronic inflammatory process that can cause valve dysfunction and threaten the durability of prosthetic valves. Bileaflet mechanical mitral valve can be implanted in either an anatomical (parallel to the anatomical axis) or nonanatomical (perpendicular or oblique to the anatomical axis) orientation. The effect of the rotational orientation of the bileaflet mechanical mitral valve on excessive pannus enlargement is unknown. The present study compared the effect of bileaflet mechanical mitral valve orientation on pannus overgrowth. METHODS: The study included patients who underwent bileaflet mechanical mitral valve replacement for rheumatic mitral valve stenosis. The pannus formation was confirmed by reexamining all transesophageal echocardiography images in the picture archiving and communication systems between May 2017 and April 2021. The primary aim of this study was the development of pannus overgrowth. Patients were divided into 2 groups based on their implantation orientation of the bileaflet mechanical mitral valve. RESULTS: Pannus overgrowth was found in 26 patients (56.5%) in the anatomical orientation group and 71 patients (74.7%) in the nonanatomical orientation group (P = 0.03). Anatomical orientation reduced the development of pannus overgrowth (odds ratio [OR] = 0.39, P = 0.04), and double left heart valve replacement increased the development of pannus overgrowth (OR = 2.73, P = 0.04). CONCLUSIONS: Pannus overgrowth was less common in bileaflet mechanical mitral valves implanted in the anatomical orientation.
RESUMEN
Right ventricular (RV) function is a determining factor for clinical outcomes in patients undergoing tricuspid valve surgery (TVS). Our aim was to investigate the importance of the function of the right ventricular outflow tract (RVOT), which is an important anatomical region of the RV, in patients underwent TVS. 104 patients who underwent TVS were analyzed retrospectively. Patients with previous cardiac surgery, congenital heart disease, or heart failure were excluded. The parasternal short-axis view at the level of the aortic root was used to measure RVOT dimensions and RVOT fractional shortening (RVOT-FS). The effect of RVOT diameter and function on major adverse cardiac events (MACE) after TVS was investigated. In our study, MACE, consisting of pacemaker implantation, acute kidney injury, postoperative atrial fibrillation and mortality, was developed at 44 (42.3%) patients.We compared the predictive performances of RVOT end-systolic (RVOTs) diameter, RVOT end-diastolic (RVOTd) diameter, RVOT-FS and RV diameters in prediction of MACE. The model including the RVOTs had higher AUC, R2 and likelihood ratio X2 values (0.775, 0.287 and 25.0, respectively) than RVOTd (0.770, 0.279 and 24.2, respectively) and RVOT-FS (0.750, 0.215 and 18.1, respectively). RVOT diameters showed better performance in predicting MACE than RV diameters. Moreover, there was statistically significant association between RVOTs, RVOTd and MACE (p value were 0.014 and 0.027, respectively), while no association between RVOT-FS and MACE (p value was 0.177). In summary, we determined that the RVOT diameters are important predictors for the in-hospital clinical outcomes of patients who underwent TVS.
RESUMEN
Background: This study aims to investigate the risk factors and surgical outcomes of conversion to median sternotomy in minimally invasive direct coronary artery bypass grafting. Methods: Between January 2017 and July 2022, a total of 274 patients (246 males, 28 females; mean age: 57.0±9.6 years; range, 33 to 81 years) who underwent conventional (n=116) or robot-assisted (n=158) minimally invasive direct coronary artery bypass grafting were retrospectively analyzed. The primary outcome measure of the study was conversion to median sternotomy, and the secondary outcome measures were operative mortality, length of intensive care unit and hospital stay. Results: Conversion to median sternotomy was required in 26 (9.5%) patients. The most common cause of conversion was intramyocardial left anterior descending artery (27.0%). Among preoperative and operative characteristics, only age was statistically significant risk factor for conversion to sternotomy (odds ratio=1.06, p=0.01). Operative mortality occurred in one patient (0.36%) patient in the entire cohort. The length of intensive care unit and hospital stay was significantly longer in patients requiring conversion to median sternotomy (p=0.002 and p<0.001, respectively). There was no significant difference in other postoperative outcomes between the two groups (p>0.05). Conclusion: Intramyocardial left anterior descending artery is the most common reason for conversion to sternotomy, and older age increases the risk of conversion. Minimally invasive coronary artery bypass grafting can be performed with satisfactory results, even if it requires conversion to sternotomy.
RESUMEN
Trace elements are essential micronutrients that take part in most antioxidant reactions in the body. In this study, we evaluated the levels of copper, chromium, manganese, selenium, magnesium, zinc, iron, and silicon in adult patients who undergone isolated on-pump coronary artery bypass with the occurrence of postoperative atrial fibrillation, transient renal injury, transient liver injury, and rate of wound infection; 51 adult patients (41 men, 10 women) underwent isolated coronary artery bypass grafting (CABG) under cardiopulmonary bypass. The mean age was 61,9 ± 8,0 years (range 45-82 years). Blood samples were collected preoperatively, postoperative first hour, postoperative first day, and fifth postoperative day for element analysis. Serum levels were determined by an Inductive Coupled Plasma Optical Emission Spectrometer (ICAP 6000). Serum copper, zinc, and selenium values, typically known as strong antioxidant elements in the body, decreased significantly during the first hour and first day of postoperative period compared to the preoperative period (p < 0.05). Also, postoperative atrial fibrillation, transient renal injury, transient liver injury, and rate of wound infection were observed to increase with the decrease in levels of trace elements (p < 0.05). The levels of these elements were observed to return to normal levels during the fifth postoperative day. The levels of trace elements decrease significantly after on-pump coronary artery bypass surgery. Our study results suggest that this could be one of the predisposing factors for increased postoperative atrial fibrillation, transient kidney injury, transient renal injury, and increased rate of wound infections for patients undergoing on-pump coronary artery bypass grafting.

ABSTRACT Introduction: Custodiol (histidine-tryptophan-ketoglutarate) and repetitive blood cardioplegia are the solutions for myocardial protection and cardiac arrest. In this study, we aimed to compare immunohistochemical analysis, clinical outcomes, and cardiac enzyme values of Custodiol and blood cardioplegia groups. Methods: This was a randomized prospective study consisting of 2 groups and 20 patients, 10 patients for each group, who underwent mitral and mitral/tricuspid valve surgery. Group 1 was formed for Custodiol cardioplegia and group 2 for blood cardioplegia. Perioperative and postoperative cardiac events were recorded, cardiac enzymes were analyzed with intervals, and myocardial samples were taken for immunohistochemical analysis. Recorded data were statistically evaluated. Results: There was no significant difference for the Custodiol and blood cardioplegia groups in perioperative and postoperative cardiac performance and adverse events. Cardiac enzyme analysis showed no significant difference between groups. However, two parameters (eNOS, Bcl-2) were in favor of the Custodiol group in immunohistochemical studies. Custodiol performed better in cellular oxidative stress resistance and cellular viability. Conclusion: Clinical outcomes and cardiac enzyme analysis results were similar regarding myocardial protection. However, Custodiol performed better in the immunohistochemical analysis.
RESUMEN
Aortitis is the inflammation of the aortic wall. In our case, in which we planned elective coronary bypass surgery, a firm and dilated ascending aorta with a pearlescent color was encountered intraoperatively. Histopathological examination revealed extensive lymphoplasmacytic infiltration and storiform fibrosis. Aortitis may be a component of a multisystemic or autoimmune disease. The time of diagnosis may coincide with the asymptomatic period of the systemic disease. This case was presented as it was incidentally detected during coronary bypass surgery and was histopathologically diagnosed as immunoglobulin G4-related aortitis, although it could not be diagnosed in clinical and laboratory evaluations.
RESUMEN
Ankylosing spondylitis is a complex chronic disease that starts from the spine and sacroiliac joint, causes joint stiffness, and affects the quality of life. Aortic dilatation, aortic valve insufficiency, and heart block due to conduction system involvement are the leading accompanying cardiac pathologies. In this case report, we aimed to show a rare cardiac involvement of left atrial calcification, pericardial involvement, and formation of a calcified inflammatory mass that might be misdiagnosed as vegetation on the mitral valve in a late-stage ankylosing spondylitis patient, by using multimodality imaging and histopathological diagnosis.

We present an interesting case of concomitant congenital anomalies with an iatrogenic defect. The female patient underwent a percutaneous mitral balloon valvuloplasty due to rheumatic mitral stenosis. Unfortunately, an iatrogenic atrial septal defect (ASD) transpired during the procedure. Upon post-procedure examination, partial anomalous pulmonary venous (PAPVR) return was observed. The patient was symptomatic; on imaging, dilatation of the right heart chambers were detected. In addition, another crucial point was that the patient was planning a pregnancy, thus robotic surgery for iatrogenic ASD and PAPVR return was recommended. After a successful operation, the patient was asymptomatic and the size of right heart chambers were normalized.

Abstract Objective: Sutureless aortic valve replacement (Su-AVR) offers an alternative to supra-annular stented biological aortic prostheses. This single-center study aimed to compare early outcomes after aortic valve replacement with sutureless and conventional stented bioprostheses. Methods: In this retrospective study, we analyzed 52 patients who underwent aortic valve replacement with sutureless and stented bioprostheses between January 2013 and October 2017. Sorin Perceval S sutureless valves were implanted in group 1 and Sorin Mitroflow stented bioprosthetic valves were used in group 2. Postoperative outcomes, including demographics, cardiopulmonary bypass (CPB) times, cross-clamp times, morbidity and mortality, as well as echocardiography in the first month, were compared. Results: Mortality occurred in 1 (3.6%) patient in group 1, and in 2 (8.3%) patients in group 2 (P=0.186). Group 1 had significantly shorter CPB (61.6±26.1 min vs. 106.3±32.7 min, P=0.001) and cross-clamp (30.9±13.6 min vs. 73.3±17.3 min, P=0.001) times. The length of stay in the intensive care unit (1.9±1.3 days vs. 2.4±4.9 days, P=0.598) and hospital stay (7.6±2.7 days vs. 7.3±2.6 days, P=0.66) were similar. Postoperatively, there was no statistically significant difference between the two groups in echocardiography results, and morbidities. The mean aortic valve gradient was 13.5±5.8 mmHg in group 1 and 14.5±8.0 mmHg in group 2 (P=0.634). Paravalvular regurgitation was diagnosed in 3 (10.7%) patients in group 1 and in 1 (4.2%) patient in group 2 (P=0.220). Conclusions: Su-AVR resulted in shorter cross-clamp and CPB times. However, early mortality, postoperative morbidity, and echocardiography results were similar between groups.
RESUMEN
Background: This study aims to investigate the effect of atriotomy approaches applied in mitral valve surgery and variations of the sinoatrial nodal artery on postoperative arrhythmias and the need for a temporary or permanent pacemaker. Methods: Data of 241 patients (108 males, 133 females, mean age: 53.7±12.3 years; range, 18 to 82 years) who underwent isolated mitral valve surgery with a median sternotomy between January 2009 and December 2019 were retrospectively analyzed. The patients were divided into three groups according to the surgical approach for mitral valve exploration as left atriotomy (n=47), transseptal (n=131), and superior transseptal (n=63). By scanning the hospital records, the origin of the sinoatrial nodal artery was determined in the coronary angiography images obtained before surgery. Postoperative rhythm changes were analyzed based on electrocardiography and telemetry recordings. Results: Temporary pacing was required in 31 (49.2%) patients in the superior transseptal group, 40 (30.5%) patients in the transseptal group, and 12 (25.5%) patients in the left atriotomy group, indicating a statistically significantly higher rate in the superior transseptal group (p=0.013). Permanent pacemaker implantation was required in only one patient (superior transseptal), indicating no significant difference among the groups. The first-degree atrioventricular block was seen in 28 (44.4%) patients in the superior transseptal group, 42 (32.1%) patients in the transseptal group, and 13 (27.7%) patients in the left atriotomy group (p=0.130). The PR interval in the postoperative period was longer in the superior transseptal group than in the left atriotomy group in patients with the sinoatrial nodal artery originating from the right coronary artery (p=0.049). No significant difference was observed among the surgical approaches regarding the PR interval in patients with the sinoatrial nodal artery originating from the left circumflex coronary artery after surgery. Conclusion: We believe that the choice of atriotomy in isolated mitral valve surgery and sinoatrial nodal artery variations do not affect permanent arrhythmia alone. Still, the superior transseptal approach causes the electrical conduction to slow down temporarily more than the left atriotomy and transseptal method.

BACKGROUND: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery. OBJECTIVES: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT. METHODS: A total of 158 obstructive PVT patients (women: 103 [65.2%]; median age 49 years [IQR: 39-60 years]) were enrolled in this multicenter observational prospective study. TT was performed using slow (6 hours) and/or ultraslow (25 hours) infusion of low-dose tissue plasminogen activator (t-PA) (25 mg) mostly in repeated sessions. The primary endpoint of the study was 3-month mortality following TT or surgery. RESULTS: The initial management strategy was TT in 83 (52.5%) patients and surgery in 75 (47.5%) cases. The success rate of TT was 90.4% with a median t-PA dose of 59 mg (IQR: 37.5-100 mg). The incidences of outcomes in surgery and TT groups were as follows: minor complications (29 [38.7%] and 7 [8.4%], respectively), major complications (31 [41.3%] and 5 [6%], respectively), and the 3-month mortality rate (14 [18.7%] and 2 [2.4%], respectively). CONCLUSIONS: Low-dose and slow/ultraslow infusion of t-PA were associated with low complications and mortality and high success rates and should be considered as a viable treatment in patients with obstructive PVT.
