Left atrial appendage perforation during appendage angiography treated by percutaneous left atrial appendage closure: a case report.
Ontology highlight
ABSTRACT: Background
Pericardial effusion is a common complication of percutaneous left atrial appendage (LAA) closure. Acute management is the cornerstone of pericardial effusion treatment and interrupting the intervention is often required.Case summary
A 65-year-old man presented an acute 10 mm pericardial effusion following pigtail contrast appendage injection. A rapid Watchman Flex 24 mm (Boston Scientific) deployment permitted bleeding interruption. A needle pericardiocentesis was achieved in order to prevent any haemodynamical instability.Discussion
This case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

Project description:BackgroundTranscatheter left atrial appendage occlusion (LAAO) using Watchman device has been demonstrated to be efficacious in decreasing stroke risk in patients with atrial fibrillation who are not suitable for long-term anticoagulation. Residual leaks are frequently encountered following LAAO procedures and their clinical implications and optimal management remain controversial.Case summaryIn this report, we describe a case of peri-Watchman device leak treated successfully with percutaneous device closure using an Amplatzer Vascular Plug II device.DiscussionThe clinical implications of peri-device leaks remain controversial with general consensus to continue anticoagulation along with serial imaging for larger leaks (>5 mm). As an alternative strategy, percutaneous closure of these leaks has been attempted in hope of avoiding anticoagulation and minimizing the risk of stroke and should be studied further.

Project description:BackgroundAtrial fibrillation (AF) is the most common cardiac arrhythmia and is a major cause of embolic stroke. In patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. Left atrial appendage (LAA) closure is an emerging option in AF patients who are not eligible for oral anticoagulation therapy because of contraindications or high bleeding risk.Case summaryA 67-year-old man with permanent AF and haemophilia was referred for further evaluation of our cardiology clinic by his primary haematologist. The CHA2DS2-VASc score was estimated to be 3 and the HAS-BLED score was 3. Due to high risk of bleeding, we decided to perform percutaneous LAA closure instead of oral anticoagulation. Pre-procedural cardiac computerized tomography angiography and transoesophageal echocardiography were performed for measurements of LAA dimensions and exclude LAA thrombus. Percutaneous LAA occlusion was performed using a 28-mm AmplatzerTM AmuletTM device. The final result was excellent without significant residual leak, pericardial effusion, and embolic complication. Clopidogrel 75?mg/day and aspirin 81?mg/day for 1?month with adequate FVIII prophylaxis and then only aspirin 81?mg/day for 2 months were recommended. No antiplatelet was given after 3 months. The patient did not report any thrombotic or haemorrhagic adverse events and there were no complications related to implanted device after 1 year of follow-up.DiscussionIn patients with hereditary bleeding disorders such as haemophilia, management of AF particularly anticoagulation can be quite challenging. In this report, we present a case of percutaneous LAA occlusion using AmplatzerTM AmuletTM device in a patient who has haemophilia and permanent AF. LAA closure has the potential to be more cost effective as compared to oral anticoagulation therapy due to lesser necessity of clotting factor infusion.

Project description:BackgroundAn 82-year-old female with a history of atrial fibrillation and repeated episodes of major bleeding on direct oral anticoagulant therapy, with a high risk for thromboembolism and was referred for left atrial appendage closure.Case summaryDuring the procedure, an unrecognized puncture of the aorta by the transseptal puncture (TSP) needle and inadvertent advancement of the sheath resulted in ascending aorta perforation. This perforation was closed percutaneously using an Amplatzer™ Duct Occluder (ADO). Reversal of heparinization with protamine sulphate was given to avoid intractable bleeding. However, this resulted in thrombus formation and subsequent embolization causing an ST-elevation myocardial infarction. This was treated with balloon dilatation and thrombus aspiration with subsequent Thrombolysis in Myocardial Infarction 3 flow.DiscussionInadvertent ascending aorta perforation is a rare yet serious complication that can occur during TSP. Percutaneous closure using an ADO is a viable management option. The reversal of heparin carries a risk of thrombus formation and should be avoided in cases where there is no evidence of overt bleeding.

Project description:BackgroundFrailty is associated with significant morbidity and mortality in older adults. Whether frailty predicts adverse outcomes after percutaneous left atrial appendage closure (LAAC) remains uncertain.ObjectiveThe purpose of this study was to examine the association between frailty and clinical outcomes after percutaneous LAAC.MethodsWe identified patients 65 years and older in Medicare fee-for-service claims who underwent LAAC between October 1, 2016, and December 31, 2019. Patients were identified as frail on the basis of the Hospital Frailty Risk Score (HFRS), a validated frailty measure centered on health resource utilization, with the cohort stratified into low (<5), intermediate (5-15), and high (>15) risk groups.ResultsOf the 21,787 patients who underwent LAAC, 10,740 (49.3%) were considered frail (HFRS >5), including 3441 (15.8%) in the high-risk group. The mortality rate (up to 1095 days) were 16.1% in the low-risk group, 26.7% in the intermediate-risk group, and 41.1% in the high-risk group (P < .001). After adjusting for age, sex, and comorbidities, HFRS >15 (compared with HFRS <5) was associated with a higher risk of long hospital stay (odds ratio [OR] 8.29; 95% confidence interval [CI] 5.94-11.57), 30-day readmission (OR 1.80, 95% CI 1.58-2.05), 30-day mortality (OR 5.68, 95% CI 3.40-9.40), and 1-year mortality (OR 2.83, 95% CI 2.39-3.35). In restricted cubic spline models, the adjusted OR for all outcomes monotonically increased with increasing HFRS.ConclusionFrailty is common in patients undergoing LAAC and is associated with increased risks of long hospital stay, readmissions, and short-term mortality.

Project description:Background:Percutaneous left atrial appendage (LAA) closure may reduce the risk of cardioembolic stroke in patients with non-valvular atrial fibrillation. Given the prophylactic nature of the procedure, identifying and managing complications are paramount. Case summary:A 73-year-old man presented 14?months after percutaneous LAA closure with syncope and acute pericardial tamponade which required surgical exploration and haemostasis; the most temporally remote account of this complication albeit amongst very few case reports. Tissue erosion by the Amplatzer™ Amulet™ LAA closure device (Abbott, Plymouth, MN, USA) was noted at two separate anatomical locations, corresponding to the device disc and lobe, which has not been described previously. Discussion:This case report highlights the anatomical relationship between the LAA and its surrounding structures, and the importance of recognizing the risk of late device erosion.

Project description:BackgroundLeft atrial appendage closure (LAAC) is considered a valid alternative for the prevention of thromboembolic stroke in patients with persistent left atrial appendage thrombus (LAAT) despite adequate anticoagulation. However, the data on LAAC using the LAmbre device for patients with LAAT is limited. This study was performed to explore efficacy and safety as well as to share the experience of the modified LAAC procedure with the LAmbre device.Materials and methodsA total of 7 patients with persistent LAAT despite adequate anticoagulation underwent modified LAAC with the LAmbre device between November 2019 and April 2022. Transesophageal echocardiography was performed 3 months postoperatively to detect device-related thrombosis and peridevice leak. The patients' clinical events were evaluated during the perioperative and follow-up periods.ResultsThe median age, CHA2DS2-VASc score, and HAS-BLED score of all patients were 71 [53-73], 3 [2-4], and 2 [2-3], respectively. In the procedure, a cerebral protection system was used in two patients. LAAC with the LAmbre device was successfully performed in all patients without perioperative events. During the median follow-up of 383 [325-865] days, postoperative transesophageal echocardiography was performed in six (85.7%) patients. Device-related thrombosis was detected in one (16.7%) patient, and no significant peridevice leak was observed. No thromboembolic event or bleeding event occurred in any patients.ConclusionLAAC with the LAmbre device is effective and safe when performed by experienced operators in highly selected patients with LAAT after adequate anticoagulation.

Project description:Patients with non-valvular atrial fibrillation (AF) and a high risk for oral anticoagulation can be treated by percutaneous implantation of left atrial appendage occlusion devices (LAAC) to reduce the risk of cardio-embolic stroke. This study evaluates whether LAAC may influence lipid metabolism, which has never been investigated before. Patients with successful LAAC were included consecutively. Venous peripheral blood samples of patients were collected immediately before (T0, baseline) and 6 months after (T1, mid-term) LAAC. A targeted metabolomics approach based on electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS/MS) and MS/MS measurements was performed. A total of 34 lipids revealed a significant change from baseline to mid-term follow-up after successful LAAC. Subgroup analysis revealed confounding influence by gender, age, diabetes mellitus type II, body mass index, left ventricular ejection fraction, creatinine and NT-proBNP. After multivariable adjustment within logistic regression models, these 34 lipids were still significantly altered after LAAC. Successful percutaneous LAAC may affect lipid metabolism and thereby may potentially affect pro-atherogenic and cardio-toxic effects.

Project description:BackgroundIn patients with non-valvular atrial fibrillation, an estimated 90% of thrombi are located in the left atrial appendage. The WATCHMAN device is a left atrial appendage closure device that is an alternative therapeutic option to reduce the risk of systemic embolization in patients who are intolerant of long-term oral anticoagulation. It can be deployed in the left atrial appendage using a transseptal approach via the femoral vein. Transhepatic venous access is an alternative route for the delivery of the device in a patient with difficult vascular access.Case summaryAn 81-year-old man with persistent non-valvular atrial fibrillation, heart failure with reduced ejection fraction (HFrEF), and diabetes mellitus was deemed a poor candidate for anticoagulation due to recurrent falls and gastrointestinal bleeding. He was selected for a left atrial appendage closure. The initial procedure was aborted after significant resistance to device advancement was encountered in the right femoral vein. Lower extremity venography demonstrated totally occluded femoral and iliac veins bilaterally. The decision was made to implant the device via a transhepatic approach. The procedure had no complications and the patient was discharged on rivaroxaban and aspirin after 3 days.DiscussionTranshepatic venous access is a viable option in patients with poor femoral access for implantation of the WATCHMAN device. It can be done safely. Knowledge of this procedural alternative can greatly enhance patient care.

Project description:Introduction Pericardial thrombosis that complicates pericardial bleeding is a life-threatening emergency in interventional cardiology, and surgery remains the only definitive treatment option. We report the first case of successful intrapericardial thrombus aspiration using a dedicated thrombus aspiration catheter in the early stage of pericardial thrombosis. Case report A 76-year-old woman with non-valve atrial fibrillation underwent percutaneous left atrial appendage (LAA) closure for secondary prevention of stroke. A 24-mm Watchman device was deployed under fluoroscopic guidance. Post-deployment angiography revealed LAA perforation, which led to the rapid onset of cardiac tamponade. Emergency pericardiocentesis was performed and the deep-seated device was redeployed at a more proximal position to seal the distal perforation. Pericardial bleeding was controlled after the drainage of 400 ml of blood. However, the patient re-developed cardiac tamponade following a period of stability. The patient was diagnosed with early-stage pericardial thrombosis based on echocardiographic findings of a hypoechoic effusion in the pericardial space. Thrombus aspiration using a pigtail catheter and long sheath failed; however, we performed successful intrapericardial thrombus aspiration using a dedicated thrombus aspiration catheter. We drained 120 ml of sludge-like blood, and the patient underwent successful conservative management without surgical intervention. Conclusion This case report highlights the potential usefulness of a percutaneous intrapericardial thrombus aspiration technique using a dedicated thrombus aspiration catheter in selected patients with early-stage pericardial thrombosis, as a less invasive alternative to cardiac surgery.
