BACKGROUND There are very few cases of cardiac occluder detachment,and it is rare to completely remove the occluder using interventional methods without undergoing thoracotomy surgery after detachment.This case innovatively used ultrasound guidance combined with digital subtraction angiography(DSA)to completely remove the occluder,accumulating some experience.CASE SUMMARY The patient underwent left atrial appendage occlusion surgery in our hospital due to atrial fibrillation.After the surgery,the occluder fell off and became free in the left ventricle,which is very dangerous.We innovatively used ultrasound guidance,combined with DSA,and interventional surgery to successfully capture the free occluder using a catcher,completely remove it,and then re implant a new left atrial appendage occluder.After the surgery,the patient recovered very well.CONCLUSION The size selection of the occluder is slightly conservative,and the shape of the left atrial appendage opening is irregular. 展开更多

BACKGROUND Inflammatory indices derived from complete blood tests have been reported to be associated with poor outcomes in patients with atrial fibrillation(AF).The data about the relationship between inflammatory indices and left atrial appendage thrombus(LAAT)or dense spontaneous echo contrast(SEC)are limited.AIM To explore the value of inflammatory indices for predicting the presence of LAAT or dense SEC in nonvalvular AF patients.METHODS A total of 406 patients with nonvalvular AF who underwent transesophageal echocardiography were included and divided into two groups based on the presence(study group)or absence(control group)of LAAT or dense SEC.Inflammatory indices,including the neutrophil-to-lymphocyte ratio(NLR),platelet–tolymphocyte ratio(PLR),and lymphocyte-to-monocyte ratio(LMR),were calculated from complete blood analysis.The associations of inflammatory indices RESULTS LAAT and dense SEC were detected in 11(2.7%)and 42(10.3%)patients,respectively.The PLR only showed an association with LAAT/dense SEC in the univariate model.Elevated NLR(odds ratio[OR]=1.48,95%confidence interval[CI]:1.11-1.98,P=0.007)and reduced LMR(OR=0.59,95%CI:0.41-0.83,P=0.003)were found to be independent risk factors for the presence of LAAT/dense SEC.The areas under the NLR and LMR curves for predicting LAAT/dense SEC were 0.73(95%CI:0.66-0.80,P<0.001)and 0.73(95%CI:0.65-0.81,P<0.001),respectively,while the cutoff values were 2.8(sensitivity:69.8%;specificity:64.0%)and 2.4(sensitivity:71.7%;specificity:60.6%),respectively.CONCLUSION Increased NLR and decreased LMR may predict LAAT/dense SEC in patients with nonvalvular AF. 展开更多

For patients with atrial fibrillation with an increased risk of stroke and contraindications to long-term anticoagulation,percutaneous left atrial appendage closure(LAAC)has become an important alternative to long-term oral anticoagulation.Incomplete closure of the LAAC during the procedure leads to faster blood flow in the interstitial space around the device,resulting in peri-device leak(PDL),which is not uncommon.Studies are still inconclusive in determining the incidence,long-term safety,and management of PDL.Therefore,this article reviewed the progress made in the research and treatment of PDL after LAAC. 展开更多

Background: Left atrial myxoma (LAM) is the most common heart tumor in adults, requiring prompt surgical removal to prevent complications like valvular obstruction or embolization. Objectives: This study aimed to compare early postoperative outcomes between two surgical approaches—right mini-thoracotomy and median sternotomy—for the removal of isolated left atrial myxoma. Methods: We conducted a prospective observational study at the Department of Cardiac Surgery, National Heart Foundation Hospital & Research Institute (NHFH&RI), Mirpur, Dhaka, from March 2017 to August 2019. Twenty-eight patients undergoing surgery for isolated left atrial myxoma were included. The surgical approach was determined by the operating surgeon. We analyzed outcomes like intubation time, Intensive Care Unit (ICU) stay, pain levels (Visual Analogue Scale score), and overall hospital stay using SPSS. Statistical significance was set at p Results: Patients in the right mini-thoracotomy group had longer mean intubation times (11.43 vs. 5.93 hours, p Conclusion: Despite longer intubation and ICU times, the right mini-thoracotomy approach offers a minimally invasive alternative for isolated left atrial myxoma excision, with favorable outcomes overall. 展开更多

An atrial septal defect (ASD) may cause right heart dysfunction, pulmonary hypertension and atrial fibrillation (AF), and atrial septal defect occlusion (ASDO) is the first choice for treating secundum defects when the morphology permits. ASD and AF frequently coexist, and the risk of AF and stroke persists after ASDO.[1] In recent years, left atrial appendage occlusion (LAAO) has been recognized as an effective treatment for stroke prevention in nonvalvular AF patients with a high risk of stroke, systemic embolism and bleeding who are unwilling to take oral anticoagulants or cannot tolerate them. 展开更多

Patient with atrial fibrillation(AF) are at risk of developing stroke with the left atrial appendage(LAA) being the most common site for thrombus formation. If left untreated, AF is associated with 4 to 5 folds increase in the risk of ischemic stroke in all age groups. About 5% to 15% of AF patients have atrial thrombi on transesophageal echocardiography, and 91% of those thrombi are located in the LAA in patient with nonrheumatic AF. Although oral anticoagulants are the gold-standard treatment for stroke prevention in patients with non-valvular AF,some patients are at high risk of bleeding and deemed not candidates for anticoagulation. Therefore, LAA occlusion(LAAO) has emerged as alternative approach for stroke prevention in those patients. Surgical LAAO is associated with high rate of unsuccessful closure and recommended only in patients with AF and undergoing cardiac surgery. Percutaneous LAAO uses transvenous access with trans-septal puncture and was first tested using the PLAATO device.Watchman is the most common and only Food and Drug Administration(FDA)approved device for LAAO. LAAO using Watchman device is non-inferior to warfarin therapy in preventing ischemic stroke/systemic thromboembolism.However, it is associated with lower rates of hemorrhagic stroke, bleeding and death. Amplatzer is another successful LAAO device that has CE mark and is waiting for FDA approval. Optimal antithrombotic therapy post LAAO is still under debate and highly patient-specific. The aim of this paper is to systematically review the current literature to evaluate the efficacy and safety of different LAAO devices. 展开更多

Transcatheter closure of the left atrial appendage has been developed as an alternative to chronic oral anticoagulation for stroke prevention in patients with atrial fibrillation, and as a primary therapy for patients with contraindications to chronic oral anticoagulation. The promise of this new intervention compared with warfarin has been supported by several, small studies and two pivotal randomized trial with the Watchman Device. The results regarding risk reduction for stroke have been favourable although acute complications were not infrequent. Procedural complications, which are mainly related to transseptal puncture and device implantation, include air embolism, pericardial effusions/tamponade and device embolization. Knowledge of nature, management and prevention of complications should minimize the risk of complications and allow transcatheter left atrial appendage closure to emerge as a therapeutic option for patients with atrial fibrillation at risk for cardioembolic stroke. 展开更多

Percutaneous left atrial appendage(LAA)occlusion evolved as an alternative treatment to the patients who are contraindicated or cannot tolerate oral anticoagulants with nonvalvular atrial fibrillation(AF)at risk of stroke or systemic embolism.[1]Abnormal hemodynamic changes in elder atrial septal defect(ASD)patients cause remodeling of the left atrium,which eventually leads to right heart failure.[2]As the ASDs elderly are associated with a higher incidence of AF,simultaneous transcatheter ASD and LAA closure has become a new effective therapeutic strategy.However,only a limited number of articles involving cardiac tamponade complications have been published in the literature.What’s more,previous studies involving early hemodynamically irrelevant pericardial effusion after the procedure attribute to multiple repositioning attempts of LAA occluder or delivery sheath injured the atrial wall. 展开更多

Non-valvular atrial fibrillation is associated with a significantly increased risk of embolic stroke due to blood clot forming predominantly in the left atrial appendage(LAA). Preventive measures to avoid embolic events are permanent administration of anticoagulants or surgical closure of the LAA. Various clinical trials provide evidence about safety, effectiveness and therapeutic success of LAA occlusion using various cardiac occluder devices. The use of such implants for interventional closure of the LAA is likely to become a valuable alternative for stroke prevention, especially in patients with contraindication for oral anticoagulation as safety, clinical benefit and cost-effectiveness of LAA occlusion has recently been demonstrated. 展开更多

AIM To evaluate the safety and efficacy of surgical left atrial appendage occlusion(s-LAAO) during concomitant cardiac surgery.METHODS We performed a comprehensive literature search through May 31 st 2018 for all eligible studies comparing s-LAAO vs no occlusion in patients undergoing cardiac surgery. Clinical outcomes during follow-up included: embolic events, stroke, all-cause mortality, atrial fibrillation(AF), reoperation for bleeding and postoperative complications. We further stratified the analysis based on propensity matched studies and AF predominance.RESULTS Twelve studies(n = 40107) met the inclusion criteria.s-LAAO was associated with lower risk of embolic events(OR: 0.63, 95%CI: 0.53-0.76; P < 0.001) and stroke(OR: 0.68, 95%CI: 0.57-0.82; P < 0.0001).Stratified analysis demonstrated this association was more prominent in the AF predominant strata. There was no significant difference in the incidence risk of allcause mortality, AF, and reoperation for bleeding and postoperative complications.CONCLUSION Concomitant s-LAAO during cardiac surgery was associated with lower risk of follow-up thromboembolic events and stroke, especially in those with AF without significant increase in adverse events. Further randomized trials to evaluate long-term benefits of s-LAAO are warranted. 展开更多

BACKGROUND In mirror-image dextrocardia,the anterior-posterior position of the cardiac chambers and great vessels is maintained,but the left-right orientation of the abdominal organs is reversed.The abnormal anatomy of the heart poses surgical challenges and problems in dealing with surgical risk and monitoring complications.There are few reports on closure of the left atrial appendage(LAA)in dextrocardia and no reports on the application of enhanced recovery after surgery(ERAS)following LAA occlusion(LAAO)procedures.CASE SUMMARY The objective for this case was to ensure perioperative safety and accelerate postoperative recovery from LAAO in a patient with mirror-image dextrocardia.ERAS was guided by the theory and practice of nursing care.Atrial fibrillation was diagnosed in a 77-year-old male patient,in whom LAAO was performed.The 2019 guidelines for perioperative care after cardiac surgery recommend that the clinical nursing procedures for patients with LAAO should be optimized to reduce the incidence of perioperative complications and ensure patient safety.Music therapy can be used throughout perioperative treatment and nursing to improve the anxiety symptoms of patients.CONCLUSION The procedure was uneventful and proceeded without complications.Anxiety symptoms were improved. 展开更多

BACKGROUND In patients who suffer from both atrial fibrillation(AF)and atrial septal defect(ASD),cryoballoon pulmonary vein isolation(PVI),sequential left atrial appendage(LAA)occlusion and ASD closure could be a strategy for effective prevention of stroke and right heart failure.CASE SUMMARY A 65-year-old man was admitted to our institution due to recurrent episodes of palpitations and shortness of breath for 2 years,which had been worsening over the last 48 h.He had a history of AF,ASD,coronary heart disease with stent implantation and diabetes.Physical and laboratory examinations showed no abnormalities.The score of CHA2DS2VASc was 3,and HAS-BLED was 1.Echocardiography revealed a 25-mm secundum ASD.Pulmonary vein(PV)and LAA anatomy were assessed by cardiac computed tomography.PV mapping with 10-pole Lasso catheter was performed following ablation of all four PVs with complete PVI.Following the cryoballoon PVI,the patient underwent LAA occlusion under transesophageal echocardiographic monitoring.Lastly,a 34-mm JIYI ASD occlude device was implanted.A follow-up transesophageal echocardiography at 3 mo showed proper position of both devices and neither thrombi nor leakage was found.CONCLUSION Sequential cryoballoon PVI and LAA occlusion prior to ASD closure can be performed safely in AF patients with ASD. 展开更多

Background For many years in ischemic heart disease, ventricles rather than atria received attention so not much is known about left atrial function in left ventricular ischemia. Objective Our study aimed to evaluate left atrial appendage (LAA) function by means of biplane transesophageal echocardiography in patients ten days after acute coronary syndromes (ACS). Methods The study was performed on 16 adult patients (65.9±9.9 years old) in whom transesophageal echocardiography was done 10 days after ACS. The following left atrial appendage (LAA) planimetric parameters were analyzed: LAA transversal dimension, LAA longitudinal dimension,LAA maximal area, and LAA minimal area. LAA ejection fraction was calculated and analyzed. The following LAA Doppler parameters were analyzed: the peak LAA emptying and the peak LAA filling velocities. The control group consisted of 14 patients (43±14.6 years old) without cardiovascular diseases. Results Both LAA longitudinal dimension and LAA transversal dimension were significantly higher in patients with ACS than in control patients. The same was observed for LAA maximal area. Also LAA ejection fraction was higher in patients with ACS . LAA minimal area did not differ in the patients in either group. LAA peak emptying flow (LAAE) and LAA peak filling flow (LAAF) were significantly higher in patients of the study group than of the control group. Conclusion Our study shows that two weeks after acute coronary syndrome LAA as a reservoir as well as a pump works at a higher level than it does in the control group.

Cardioembolic events are one of the most feared complications in patients with non-valvular atrial fibrillation(NVAF) and a formal contraindication to oral anticoagulation(OAC).The present case report describes a case of massive peripheral embolism after an implantable cardiac defibrillator(ICD) shock in a patient with NVAF and a formal contraindication to OAC due to previous intracranial hemorrhage.In order to reduce the risk of future cardioembolic events,the patient underwent percutaneous left atrial appendage(LAA) occlusion.A 25 mm AmplatzerTM Amulet was implanted and the patient was discharged the following day without complications.The potential risk of thrombus dislodgement after an electrical shock in patients with NVAF and no anticoagulation constitutes a particular scenario that might be associated with an additional cardioembolicrisk.Although LAA occlusion is a relatively new technique,its usage is rapidly expanding worldwide and constitutes a very valid alternative for patients with NVAF and a formal contraindication to OAC. 展开更多

Background Cryoballoon ablation has been demonstrated to be an effective way for the treatment of atrial fibrilation(AF).However,in the population with high risk of thromboembolism,long-term oral anticoagulants are still in need,which lead to the odds of hemorrhage.As previous studies confirmed,left atrial appendage closure(LAAC)could decrease the risk of thromboembolism in AF patients,and may substitute for the long term anticoagulation.Therefore,we attempted to combine both these operations for AF. 展开更多
