[Ab] Resumo:The atrioventricular (AV) groove constitutes the anatomic space separating the atria and ventricles. The AV groove is often difficult to visualize at echocardiography, and suspected lesions can be further assessed with cardiac computed tomography or magnetic resonance imaging. AV groove lesions may originate from within the AV groove or extend into this space from adjacent structures. The differential diagnosis for AV groove lesions is often wide, but a precise diagnosis can sometimes be made. This pictorial essay illustrates the magnetic resonance imaging and computed tomography appearance of common and uncommon AV groove lesions, and attempts to provide a logical framework for differential diagnosis when confronted with a known or suspected lesion at cross-sectional imaging.

[Ab] Resumo:INTRODUCTION: Surgical ablation is a generally established treatment for patients with atrial fibrillation undergoing concomitant cardiac surgery. Left atrial (LA) lesion set for ablation is a simplified procedure suggested to reduce the surgery time and morbidity after procedure. The present meta-analysis aims to explore the outcomes of left atrial lesion set versus no ablative treatment in patients with AF undergoing cardiac surgery. METHODS: A literature research was performed in six database from their inception to July 2017, identifying all relevant randomized controlled trials (RCTs) comparing left atrial lesion set versus no ablative treatment in AF patient undergoing cardiac surgery. Data were extracted and analyzed according to predefined clinical endpoints. RESULTS: Eleven relevant RCTs were included for analysis in the present study. The prevalence of sinus rhythm in ablation group was significantly higher at discharge, 6-month and 1-year follow-up period. The morbidity including 30 day mortality, late all-cause mortality, reoperation for bleeding, permanent pacemaker implantation and neurological events were of no significant difference between two groups. CONCLUSIONS: The result of our meta-analysis demonstrates that left atrial lesion set is an effective and safe surgical ablation strategy for AF patients undergoing concomitant cardiac surgery.

[Ab] Resumo:A 74-year-old man with a past medical history of bradycardiac atrial fibrillation and an old cerebral infarction presented with dysarthria. He had been treated with warfarin and PT-INR on admission was 2.0. MRI of the head revealed an acute ischemic stroke involving the cerebellum and left occipital lobe. Because transesophageal cardiac echography showed a thrombus in the left atrial appendage, anticoagulant treatment with warfarin and heparin was initiated. The thrombus was enlarging; therefore, we changed the anticoagulant therapy to apixaban with heparin on day 11. On day 17, a hemorrhagic cerebral infarction occurred. After the hemorrhage diminished, we treated him with warfarin aiming for a PT-INR between 3 and 4. The thrombus gradually shrank and disappeared on day 110. Finally, a thoracoscopic left atrial appendectomy was performed as a secondary prevention, with no recurrence till date.

[Ab] Resumo:BACKGROUND: Compared with left atrial (LA) dimension, LA emptying fraction (LAEF) has received less emphasis as a predictor of atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). In addition, patients experiencing post-RFCA AF recurrence may respond to previously ineffective antiarrhythmic drugs (AADs). Classifying these patients into a third RFCA outcome category is recommended. OBJECTIVE: To identify predictors of RFCA outcome classified into three categories, and to build proportional odds logistic regression models for clinical applicability to predict AF recurrence. METHODS: Data were retrospectively collected from 483 consecutive patients with drug-refractory AF undergoing RFCA (328 men; age 58.4 ± 11.5 years; 383 paroxysmal). Patients were classified into 3 groups based on the last RFCA outcome: group 1, free from AF without AADs; group 2, free from AF with AADs; and group 3, recurrence of AADs-refractory atrial tachyarrhythmia. RESULTS: After a mean follow-up duration of 64.5 ± 43.2 months and mean ablation procedure number of 1.37 ± 0.68, the RFCA outcome showed 76.0%, 9.5% and 14.5% of patients in groups 1, 2, and 3, respectively. In multivariate analysis, LAEF was the most stable and important predictor of AF recurrence, followed by body mass index, stroke, AF duration, mitral regurgitation, and LA linear ablation. For patients undergoing repeat RFCA, LAEF was the only independent predictor (cutoffs: 43% and 35% for groups 1 and 3, respectively). CONCLUSION: LAEF provides optimal prognostic information regarding the risk stratification of AF patients undergoing RFCA.

[Ab] Resumo:BACKGROUND: Both ambulatory atrial fibrillation (AF) and post-operative AF (poAF) are associated with substantial morbidity and mortality. Analyzing the tissue-specific gene expression in the left atrium (LA) can identify novel genes associated with AF and further the understanding of the mechanism by which previously identified genetic variants associated with AF mediate their effects. METHODS: LA free wall samples were obtained intraoperatively immediately prior to mitral valve surgery in 62 Caucasian individuals. Gene expression was quantified on mRNA harvested from these samples using RNA sequencing. An expression quantitative trait loci (eQTL) analysis was performed, comparing gene expression between different genotypes of 1.0 million genetic markers, emphasizing genomic regions and genes associated with AF. RESULTS: Comparison of whole-genome expression between patients who later developed poAF and those who did not identified 23 differentially expressed genes. These included genes associated with the resting membrane potential modified by potassium currents, as well as genes within Wnt signaling and cyclic GMP metabolism. The eQTL analysis identified 16,139 cis eQTL relationships in the LA, including several involving genes and single nucleotide polymorphisms (SNPs) linked to AF. A previous relationship between rs3744029 and MYOZ1 expression was confirmed, and a novel relationship between rs6795970 and the expression of the SCN10A gene was identified. CONCLUSIONS: The current study is the first analysis of the human LA expression landscape using high-throughput RNA sequencing. Several novel genes and variants likely involved in AF pathogenesis were identified, thus furthering the understanding of how variants associated with AF mediate their effects via altered gene expression.

[Ab] Resumo:BACKGROUND: Fat embolism is a common complication of orthopedic surgery. However, the exact component and risk factor responsible for this complication remains unelucidated. This study aimed to detect the origin of the pulmonary embolus and identify relevant risk factors of pulmonary embolism in total knee replacement. METHODS: A total of 40 osteoarthritis patients who underwent primary unilateral TKA were recruited into this study. Transesophageal echocardiography (TEE) was utilized to dynamically monitor the embolism. Pulmonary arterial pressure was recorded and biopsies were obtained from the medullary cavity during surgery. RESULTS: After tourniquet release, the arterial embolism was observed by TEE to have a peak signal at 30 seconds when pulmonary arterial pressure was increased by 25% to 40% (P = .002). The pathology study of the embolism revealed its bone marrow origin. Total embolus quantity was positively correlated with age (P = .021), body mass index (BMI, P = .041), and fat content of the bone marrow (P = .003). Logistic regression analysis revealed that the fat content of the marrow (OR: 1.432, 95% CI: 1.335-1.592), age (OR: 1.632, 95% CI: 1.445-1.832), and BMI (OR: 1.231, 95% CI: 1.032-1.381) were risk factors for pulmonary hypertension. CONCLUSION: This study revealed that the embolus detected in the right atrium was derived from bone marrow tissues, and this led to pulmonary arterial pressure fluctuations after tourniquet release. Therefore, elderly patients who have high BMI or bone marrow fat content are at high-risk for pulmonary fat embolism during TKA.

[Ab] Resumo:BACKGROUND: The increased incidence of preoperative and postoperative arrhythmia in Ebstein anomaly (EA) prompted some clinicians to perform an electrophysiology study (EPS) in all patients prior to surgery for EA. The cone repair (CR) is the current surgical option of choice for most young patients with EA but the effect of the CR on arrhythmia is not well established. OBJECTIVES: To assess the burden of arrhythmia in young patients after CR and to assess the utility of selective preoperative EPS. MATERIALS AND METHODS: A retrospective review of all patients <21 years of age with EA who had a CR at Mayo Clinic from June 2007 to December 2015 was performed. Surveys were mailed and telephone calls were made to all individuals to assess antiarrhythmic medication use and EP/device procedures performed after CR. RESULTS: There were 143 patients; median age, 10 years (0.1-20.9 years). Thirty-five (24%) patients had a preoperative EPS of which 26 (18%) had a preoperative ablation. Indications for EPS were Wolff-Parkinson-White (WPW), documented arrhythmia, or suspected arrhythmia. Posthospital discharge data were available for 140 (98%) patients. Mean follow-up was 2.9 years (0.1-9.2 years). At follow-up, 7 (5%) patients were receiving antiarrhythmic medications. After CR, only 3 (2%) patients who did not have a preoperative EPS have required an ablation. CONCLUSIONS: The risk of arrhythmia after CR for EA in young patients is very low when a preoperative EPS is limited to those with WPW, known arrhythmia, or suspected arrhythmia. In smaller patients, it may be reasonable to defer the EPS.

[Ab] Resumo:The median sternotomy remains the standard approach in cardiovascular surgery but, in some conditions, it can be considered difficult to perform, especially in patients with history of esophagectomy. This case report describes a successful resection of a left atrial myxoma through a right anterolateral thoracotomy approach in a patient with a previous retrosternal gastric tube reconstruction. The decision for the best surgical approach was made after a heart surgery team discussion. Through this surgical access, a safe and excellent exposure of the left atrium was possible, and a complete resection of the myxoma was performed without any injury to the gastric tube.

[Ab] Resumo:Right ventricular pacing often results in prolonged QRS duration (QRSd) as the result of right ventricular stimulation, and atrial fibrillation (AF) may result. The association of pacing-induced prolonged QRSd and AF in patients with permanent pacemakers is unknown.We selected 180 consecutive patients who underwent pacemaker implantation for complete/advanced atrioventricular block. All of the patients were paced from the right ventricular septum. Electrocardiography recordings were obtained at the beginning and the end of pacemaker implantation. QRSd was measured in all 12 leads. The QRSd variation was calculated by subtracting the preimplantation QRSd from the postimplantation QRSd.The occurrence of AF was observed in 64 (35.56%) patients (follow-up 33.62 ±â€Š21.47 mo). No significant differences in preimplantation QRSd were observed between the AF occurrence and nonoccurrence groups. The QRSd variation in leads V4 (54.22 ±â€Š29.03 vs 42.66 ±â€Š33.79 ms, P = .022), and V6 (64.62 ±â€Š23.16 vs 48.45 ±â€Š34.40 ms, P = .001) differed significantly between the occurrence and nonoccurrence groups. More QRSd variation in lead V6 (P = .005, HR = 1.822, 95% CI 1.174-2.718, interval scale of QRSd was 40 ms) and left atrial diameter (P = .045, HR = 1.042, 95% CI 1.001-1.086) were independent risk factors for AF occurrence. Receiver operating characteristic curve suggested that QRSd variation in lead V6 could predict AF occurrence, especially for patients with long preimplantation QRSd (≥120 ms, area under the curve was 0.826, 95% CI 0.685-0.967).QRSd variation in lead V6 might be positively correlated with postimplantation AF occurrence. In patients with pacemaker implantation, QRSd could be a complementary criterion for optimizing the right ventricular septal pacing site, and smallest QRSd might be worth pursuing.
