Atrial septal defect (ASD) is the common congenital anomaly which requires surgical interventions. Right atrial thrombus formations after primary suture repairs of the ASD and evidences of thromboembolic complications are extremely rare. Specifically, the cases of thromboembolic complications have high mortality and morbidity risks. Two cases of giant intra-atrial thrombus formation detected in the late stage after primary repairs of ASDs are being discussed.

Mild pulmonary hypertension (mean SPAP = 37.7 ± 8.4 mmHg) was not associated with a significant difference in the mortality of patients undergoing coronary artery bypass grafting. For patients undergoing this type of coronary bypass surgery, lower morbidity and mortality rates can be achieved through comprehensive preoperative examinations and effective perioperative medical procedures.

Hyperimmunoglobulin E syndrome (HIES) is an immunodeficiency disorder that manifests itself by affecting more than one system. Arterial aneurysms are among the significant complications associated with HIES. Surgical procedures for patients with such aneurysms are uncommon. In this study, we aim to present the case and surgical repair of a male child who was previously diagnosed with HIES and presented with rapidly expanding ascending aortic aneurysm.

IntroductionPulmonary hypertension (PH) is one of the main causes of increased mortality and morbidity rates in open heart surgery. Left heart disease is probably the most frequent cause of PH. 1) Left-sided ventricular or valvular diseases may lead to an increase in left atrial pressure, and the passive backward transmission of this pressure may result in increased pulmonary arterial pressure (PAP). 2) Despite intensive postoperative medical treatment, an increase is observed in mortality and morbidity rates following coronary bypass surgery in patients with PH and right heart failure. 3,4) PH has a significant effect on right ventricular afterload. Various studies have shown that patients with right ventricle dysfunction display higher rates of early perioperative mortality and poor long term survival. 5,6) In this study, we investigated the effect of preoperative PH on the early-and long term results of patients who underwent isolated coronary artery bypass surgery, as well as its effect on the quality of life and the changes in The late mortality of cases was 5.79%. In our study, during 33.9 ± 17 (9-100) months follow up period, life expectancy was calculated as 94.7 months. Conclusion: Preoperative evaluation of these patients for appropriate medical treatment at peroperative and postoperative period, coronary bypass can be performed with low morbidity and mortality rates. In the late period after surgical revascularization PH showed no significant change and had no adverse effect on quality of life.

Aim: Several factors are known to be associated with arrhythmias after cardiac surgery. This paper examines the changes in thyroid hormones after cardiac surgery and the relationship with arrhythmias. Material and Methods: A random sample of euthyroid patients scheduled for isolated coronary artery bypass surgery were recruited for a randomized prospective study. Patients were divided into two groups based on developing a new-onset arrhythmia (NOA) or atrial fibrillation (NOAF) after surgery (Group 2, n=18), and patients without NOA or NOAF after surgery were included in Group 1 (n=66). Blood samples for free triiodothyronine (fT3) and free thyroxin (fT4) levels were collected preoperatively and at the time of arrival to intensive care unit (D0), 24th hour (D1), 48th hour (D2), 72nd hour (D3) and 96th hour (D4). Results: Arrhythmia was detected in 21.43% of patients. Twelve patients had NOAF and six patients had ventricular NOA. The postoperative second day was the most common day for arrhythmia. fT3 values were lower than preoperative values in both groups. When intra-group decreases were compared, the fT3 value decrease was more prominent in the arrhythmia group and fT3 regression at the D2 term (p=0.036) was especially significant. Postoperative fT4 values were higher than preoperative values in both groups. When intra-group raises were compared, fT4 values increased in both groups. This raising was more significant in the arrhythmia group and the fT4 rise at D1 term (p=0.022) was especially important. Conclusion: The decrease of fT3 values in the arrhythmia group (Group 2) was greater. This is more prominent on the postoperative second day, which is the most common day for arrhythmia after cardiac surgery. There is a rise in fT4 values and this is higher in the arrhythmia group. These relatively high values may be mimicking hyperthyroidism and may be considered a predisposition for arrhythmia and atrial fibrillation.
