Objective: Atrial fibrillation (AF) is the most common arrhythmia following coronary artery by-pass graft surgery (CABG). The value of SYNTAX score to predict postoperative atrial fibrillation (PoAF) has not been clearly addressed. We aimed to evaluate this relationship in patients undergoing isolated CABG. Methods: This study was designed as a single-center, non-randomized, observational, prospective study. Ninety-four patients undergoing isolated on-pump CABG, who had sinus rhythm and were older than 18 years, were enrolled. Demographic characteristics of the patients were recorded; SYNTAX score was calculated preoperatively for each patient. The univariate and multivariate logistic regression analysis were used to determine for predictors of PoAF. Results: The median SYNTAX score of the enrolled patients was 21, (56-5). PoAF was observed in 31 (33.3%) patients. Univariate logistic regression showed that age, chronic obstructive pulmonary disease (COPD), red blood cell distribution width (RDW), urea, initial troponin I, peak postoperative troponin I, interventricular septum, left atrial diameter, and SYNTAX score were significantly associated with the frequency of PoAF following CABG. An independent association was identified with age [β: 0.088, p:0.023, OR: 1.092, 95% CI (1.012-1.179)], COPD [(β: 2.222, p:0.003, OR: 9.228, 95% CI (2.150-39.602)], and SYNTAX score [(β: 0.130, p:0.002, OR: 1.139, 95% CI (1.050-1.235)]. Conclusion: This study showed that a higher SYNTAX score was related to more frequent PoAF in patients undergoing isolated on-pump CABG. [ABSTRACT FROM AUTHOR]

The article describes the case of a 25-year old male whose transthoracic echocardiography revealed mild tricuspid valve regurgitation and mild right chamber dilation. Transesophageal echocardiograpy (TEE) was performed to determine etiology of pulmonary hypertension (PHT). TEE showed an anomalous left upper pulmonary vein separated from the left atrium by a septum and the left upper and lower pulmonary veins were both draining to the coronary sinus that highlights a very rare case of PHT.

Aim: Current literature lacks a definitive threshold of idiopathic premature ventricular complex (PVC) burden for predicting cardiomyopathy (CMP). The main objective of the present study was to evaluate relationship between the PVC burden and left ventricular ejection fraction (LVEF)., Method: This multicenter, cross-sectional study included 341 consecutive patients with more than 1,000 idiopathic PVC in 24 hr of Holter monitoring admitted to the cardiology clinics between January 2019 and May 2019 in the nineteen different centers. The primary outcome was the LVEF measured during the echocardiographic examination., Result: Overall, the median age was 50 (38-60) and 139 (49.4%) were female. Percentage of median PVC burden was 9% (IQR: 4%-17.4%). Median LVEF was found 60% (55-65). We used proportional odds logistic regression method to examine the relationship between continuous LVEF and candidate predictors. Increase in PVC burden (%) (regression coefficient (RE) -0.644 and 95% CI -1.063, -0.225, p < .001), PVC QRS duration (RE-0.191 and 95% CI -0.529, 0.148, p = .049), and age (RE-0.249 and 95% CI -0.442, -0.056, p = .018) were associated with decrease in LVEF. This inverse relationship between the PVC burden and LVEF become more prominent when PVC burden was above 5%. A nomogram developed to estimate the individual risk for decrease in LVEF., Conclusion: Our study showed that increase in PVC burden %, age, and PVC QRS duration were independently associated with decrease in LVEF in patients with idiopathic PVC. Also, inverse relationship between PVC burden and LVEF was observed in lower PVC burden than previously known., (© 2019 The Authors.

Endocardial cushion defect (ECD) can be partial (with two distinct valves) or complete (only one atrioventricular valve), and surgical therapy is usually required. The optimal surgical technique is controversial but De Vega's annuloplasty is widely performed. Tricuspid valve thrombosis are rarely seen after surgery. We present a 39-year-old male patient with tricuspid valve thrombosis after De Vega's annuloplasty without the use of a ring.
