Abstract
BACKGROUND Thromboembolic occlusion of the superior mesenteric artery (SMA) is a grave complication in individuals diagnosed with atrial fibrillation (AF). This condition often necessitates extensive bowel resection, culminating in short bowel syndrome, which presents challenges for anticoagulant administration and/or antiarrhythmic therapy. CASE PRESENTATION Presented here are findings of two patients, aged 78 and 72 years, respectively, who underwent comprehensive thoracoscopic AF surgery subsequent to extensive small bowel resection following SMA embolization. In each, onset of AF precipitated an embolic event, while the concurrent presence of short bowel syndrome complicated anticoagulation management. Total thoracoscopic AF surgery, comprised stapler-closure of the left atrial appendage (LAA) and bilateral epicardial clamp-isolation of the pulmonary veins, an operative modality aimed at addressing AF rhythm control and mitigating embolic events such as cerebral infarction, led to favorable outcomes in both cases. Additionally, computed tomography (CT) conducted one month post-surgery revealed the absence of residual tissue in the LAA, with the left atrium demonstrating a well-rounded, spherical shape. At the time of writing, the patients have remained asymptomatic following surgery regarding thromboembolic and arrhythmic manifestations for 29 and 10 months, respectively, notwithstanding the absence of anticoagulant or antiarrhythmic pharmacotherapy. Additionally, electrocardiographic surveillance has revealed persistent sinus rhythm. CONCLUSIONS The present findings underscore the feasibility and efficacy of a total thoracoscopic AF surgery procedure for patients presented with short bowel syndrome complicating SMA embolization, thus warranting consideration for its broader clinical application.

Systematic review and meta-analysis of left atrial appendage closure's influence on early and long-term mortality and stroke. JTCVS OPEN 2024; 19:131-163. [PMID: 39015454 PMCID: PMC11247209 DOI: 10.1016/j.xjon.2024.02.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/17/2023] [Accepted: 02/08/2024] [Indexed: 07/18/2024]
Abstract
Objective Left atrial appendage closure (LAAC) concomitant to heart surgery in patients with underlying atrial fibrillation (AF) has gained attention because of long-term reduction of thromboembolic complications. As of mortality benefits in the setting of non-AF, data from both observational studies and randomized controlled trials are conflicting. Methods On-line databases were screened for studies comparing LAAC versus no LAAC concomitant to other heart surgery. End points assessed were all-cause mortality and stroke at early and longest-available follow-up. Subgroup analyses stratified on preoperative AF were performed. Risk ratios (RR) with 95% CIs served as primary statistics. Results Electronic search yielded 25 studies (N = 660 [158 patients]). There was no difference between LAAC and no LAAC in terms of early mortality. In the overall population analysis, LAAC reduced long-term mortality (RR, 0.86; 95% CI, 0.74-1.00; P = .05; I 2 = 88%), reduced early stroke risk by 19% (RR, 0.81; 95% CI, 0.72-0.93; P = .002; I 2 = 57%), and reduced late stroke risk by 13% (RR, 0.87; 95% CI, 0.84-0.90; P < .001; I 2 = 58%). Subgroup analysis showed lower mortality (RR, 0.85; 95% CI, 0.72-1.01; P = .06; I 2 = 91%), short-, and long-term stroke risk reduction only in patients with preoperative AF (RR, 0.81; 95% CI, 0.71-0.93; P = .003; I 2 = 71% and RR, 0.87; 95% CI, 0.84-0.91; P < .001; I 2 = 70%, respectively). No benefit of LAAC in patients without AF was found. Conclusions Concomitant LAAC was associated with reduced stroke rates at early and long-term and possibly reduced all-cause mortality at the long-term follow-up but the benefits were limited to patients with preoperative AF. There is not enough evidence to support routine concomitant LAAC in non-AF settings.

[PMID: 38360343 DOI: 10.1016/j.athoracsur.2024.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 01/24/2024] [Accepted: 02/05/2024] [Indexed: 02/17/2024]
Abstract
BACKGROUND The clinical implications of acute phase thrombosis after surgical left atrial appendage (LAA) closure remain unclear. This study sought to determine the frequency, prognosis, and factors involved in thrombogenesis after surgical LAA occlusion. METHODS In this study, data from patients who underwent 2 types of standalone surgical LAA closure (either resection or clipping) between July 2014 and March 2020 at a single center were analyzed. RESULTS A total of 239 consecutive patients with atrial fibrillation underwent minimally invasive standalone surgical LAA occlusion (184 resection cases and 55 clipping cases). On postoperative day 2, electrocardiogram synchronized contrast-enhanced computed tomography (CT) was performed in 223 cases (93.3%), and echocardiography follow-up was performed in 16 cases when CT was contraindicated. Acute postoperative thrombus on the closed stump was detected in 35 cases (14.7%), of which 29 cases (15.8%) belonged to the resection group and 6 cases (10.9%) belonged to the clipping group. No significant difference was detected between the groups, and no significant predictors of acute-phase thrombosis were found. Thromboembolism occurred in 4 patients before postoperative imaging follow-up, and there was no evidence of thrombi in these patients on postoperative day 2 CT. Three months after the first CT, thrombi were no longer detected in 34 of 35 patients (97.1%). CONCLUSIONS Thrombosis can occur after surgical LAA occlusion. Although the clinical significance is yet unclear, it may be reasonable to continue anticoagulation therapy until a lack of thrombosis is confirmed, unless there are contraindications.

Abstract
OBJECTIVE The present study evaluated the differences between left atrial appendage occlusion (LAAO) and left atrial appendage resection (LAAR) in terms of the safety and efficacy. MATERIALS AND METHODS From January 2018 to August 2022, 94 patients underwent a stand-alone LAAO, and 90 patients underwent stand-alone LAAR in our institution. All of these patients were included in this study. LAAO was performed via left mini-thoracotomy, and LAAR was performed via a left thoracoscopic approach. The patients' characteristics and perioperative and postoperative data were obtained by retrospectively reviewing their medical records. RESULTS The mean age of the patients was 72.4 ± 10.2 (LAAO) and 66.2 ± 9.4 (LAAR) years old (P < 0.05). There were no marked differences in the mean duration of atrial fibrillation (AF) or the ratio of AF type between both groups. The average CHA2DS2-Vasc scores were 4.4 ± 1.6 (LAAO) and 2.7 ± 1.8 (LAAR) (P < 0.05), and the average HAS-BLED scores were 2.9 ± 1.0 (LAAO) and 2.2 ± 1.2 (LAAR) (P < 0.05). The mean operation time was 49 ± 20 min (LAAO) and 34 ± 15 min (LAAR) (P < 0.05). No substantial gaps were detected in preoperative echo-graphic findings between the groups. No significant differences were observed in the amount of intraoperative or postoperative bleeding or the rate of intraoperative massive bleeding events between the groups. Successful LAA closure was achieved in all cases in both groups. Approximately 50% of patients underwent concomitant left pulmonary vein isolation (LPVI) during surgery, indicating no significant differences between the groups (P = 0.872). The early mortality rate was 1.04% in the LAAO group and 0% in the LAAR group (P = 0.132). There was no significant difference in the rate of postoperative LAA stump thrombus between the groups (8.5% in the LAAO group and 6.7% in the LAAR group; P = 0.320). The mean follow-up period was 851 ± 500 (6-1618) days in the LAAO group and 1208 ± 357 (49-1694) days in the LAAR group. Postoperative stroke events were detected in 1 patient in each group (P = 0.432). There was no significant difference in the sinus rhythm recovery rate after LPVI between these groups (31.1% in the LAAO group and 28.6% in the LAAR group; P = 0.763). CONCLUSION There were no significant differences between LAAO and LAAR in terms of the feasibility and the effectiveness as a method for stroke prophylaxis only to selected patients for both procedures, although further studies including the comparison between groups with the same backgrounds to confirm the authentic differences in the clinical results between these procedures.

Abstract
BACKGROUND The prognostic effect of concomitant hypertrophic cardiomyopathy (HCM) on adverse events in patients with atrial fibrillation (AF) has not been evaluated in a multicenter prospective cohort study in Japan.Methods and Results: Using the Hokuriku-Plus AF Registry, 1,396 patients with nonvalvular AF (1,018 men, 72.3±9.7 years old) were assessed prospectively; 72 (5.2%) had concomitant HCM. During a median follow-up of 5.0 years (interquartile range 3.5-5.3 years), 79 cases of thromboembolism (1.3 per 100 person-years) and 192 of heart failure (HF) (3.2 per 100 person-years) occurred. Kaplan-Meier analysis revealed that the HCM group had a significantly greater incidence of thromboembolism (P=0.002 by log-rank test) and HF (P<0.0001 by a log-rank test) than the non-HCM group. The Cox proportional hazards model demonstrated that persistent AF (adjusted hazard ratio 2.98, 95% confidence interval 1.56-6.21), the CHA2DS2-VASc score (1.35, 1.18-1.54), and concomitant HCM (2.48, 1.16-4.79) were significantly associated with thromboembolism. Conversely, concomitant HCM (2.81, 1.72-4.43), older age (1.07, 1.05-1.10), lower body mass index (0.95, 0.91-0.99), a history of HF (2.49, 1.77-3.52), and lower left ventricular ejection fraction (0.98, 0.97-0.99) were significantly associated with the development of HF. CONCLUSIONS Concomitant HCM predicts the incidence of thromboembolism and HF in AF patients.

Heart Team for Left Appendage Occlusion without the Use of Antithrombotic Therapy: The Epicardial Perspective. J Clin Med 2022; 11:6492. [PMID: 36362719 PMCID: PMC9656641 DOI: 10.3390/jcm11216492] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 10/25/2022] [Accepted: 10/28/2022] [Indexed: 07/03/2024] Open
Abstract
BACKGROUND Left atrial appendage occlusion is an increasingly proposed treatment for patients with atrial fibrillation and poor tolerance to anticoagulants. All endovascular devices require antithrombotic therapy. Anatomical and clinical variables predisposing to device-related thrombosis, as well as post-procedural peri-device leaks, could mandate the continuation or reintroduction of aggressive antithrombotic treatment. Because of the absence of foreign material inside the heart, epicardial appendage closure possibly does not necessitate antithrombotic therapy, but data of large series are missing. METHODS Multidisciplinary team evaluation for standalone totally thoracoscopic epicardial appendage closure was done in 180 consecutive patients with atrial fibrillation and poor tolerance to antithrombotic therapy. One hundred and fifty-two patients consented (male 66.1%, mean age 76.1 ± 7.4, CHA2DS2VASc mean 5.3 ± 1.6, HASBLED mean 3.8 ± 1.1). Indications were cerebral hemorrhage (48%), gastro-intestinal bleeding (33.3%), and other bleeding (20.7%). No antithrombotic therapy was prescribed from the day of surgery to the latest follow up. RESULTS Procedural success was 98.7%. At a mean follow up of 38.2 ± 18.8 months, cardioembolic and bleeding events were 1.3% and 0.6%, respectively. Among patients with a history of blood transfusions (41.1%), none needed further transfusions or treatment post procedure. CONCLUSION Epicardial appendage occlusion without any antithrombotic therapy appears to be safe and effective. This strategy could be advised when minimization of bleeding risk concomitant to stroke prevention is needed.

ASIA 2022; 2:519-537. [PMID: 36624790 PMCID: PMC9823285 DOI: 10.1016/j.jacasi.2022.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 05/29/2022] [Accepted: 06/22/2022] [Indexed: 01/12/2023]
Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with substantial increases in the risk for stroke and systemic thromboembolism. With the successful introduction of the first non-vitamin K antagonistdirect oral anticoagulant agent (NOAC) in 2009, the role of vitamin K antagonists has been replaced in most clinical settings except in a few conditions for which NOACs are contraindicated. Data for the use of NOACs in different clinical scenarios have been accumulating in the past decade, and a more sophisticated strategy for patients with AF is now warranted. JACC: Asia recently appointed a working group to summarize the most updated information regarding stroke prevention in AF. The aim of this statement is to provide possible treatment options in daily practice. Local availability, cost, and patient comorbidities should also be considered. Final decisions may still need to be individualized and based on clinicians' discretion. This is part 2 of the statement.

Abstract
AbstractAtrial fibrillation (AF) is the most common and increasing cardiac arrhythmia. AF increases thromboembolic events and hospitalizations and deteriorates quality of life. The mechanism of AF is not completely understood. James Cox proposed a concept of Maze procedure in 1987 which was based on a surgical ablation lesion for electrical conduction pathway. Although surgical ablation offers a higher success rate, it should be performed with minimally invasive techniques because of its high invasiveness. Haissaguerre et al. identified potential sources of AF in the pulmonary veins as triggers and developed the percutaneous catheter ablation as the treatment strategy for paroxysmal AF refractory to pharmaceutical therapy. The atrial remodeling occurs electrically and structurally in persistent or longstanding persistent AF, and the catheter ablation and surgical ablation have variable success rates. Persistent or longstanding persistent AF presents a major challenge. Despite continuous improvements, catheter-based procedures have shown relatively far from satisfactory outcomes and may need to be repeated to achieve sinus rhythm. A hybrid approach consisting of the sequential combination of a surgical minimally invasive epicardial ablation and a transvenous catheter endocardial ablation would be an alternative option that supplements the limitations of endo- and epicardial strategies. Close cooperation between cardiac surgeons and electrophysiologists for optimal selection of patients and management for arrhythmia recurrence seems suggestible for persistent or longstanding persistent AF.

Abstract
BACKGROUND AND PURPOSE Left atrial appendage occlusion (LAAO) is an accepted therapeutic option for stroke prevention; however, the ideal technique and device have not yet been identified. In this study we evaluate the potential role of a heart team approach for patients contraindicated for oral anticoagulants and indicated for left atrial appendage closure, to minimize risk and optimize benefit in a patient-centered decision-making process. METHODS Forty patients were evaluated by the heart team for appendage occlusion. Variables considered were CHA2DS2VASc, HASBLED, documented blood transfusions, comorbidities, event forcing anticoagulant interruption, past medical history, anatomy of the left atrial appendage, and patient quality of life. Twenty patients had their appendage occluded percutaneously (65% male, mean age 72.3 ± 7.5, mean CHA2DS2VASc 4.2 ± 1.5, mean HASBLED 3.5 ± 1.1). The other twenty underwent thoracoscopic occlusion (65% male, mean age of 74.9 ± 8, mean CHA2DS2VASc 6.0 ± 1.5, HASBLED mean 5.4 ± 1.4). Percutaneous patients were on dual antiplatelet therapy for the first three months and aspirin thereafter, whereas the others received no anticoagulant/antiplatelet therapy from the day of surgery. Follow up included TEE, CT scan, and periodical clinical evaluation. RESULTS Mean duration of procedures and hospital stay were comparable. All patients had complete exclusion of the appendage; at a mean follow up of 33.1 ± 14.1 months, no neurological or hemorrhagic events were reported. CONCLUSIONS A heart team approach may improve the decision-making process for stroke and hemorrhage prevention, where LAAO is a therapeutic option. Percutaneous and thoracoscopic appendage occlusion seem to be comparably safe and effective. An epicardial LAAO could be advisable in patients for whom the risk of bleeding is estimated as being too high for post-procedural antiplatelet therapy.

Abstract
We report a bilateral thoracoscopic technique in which robot-assisted mitral
valve repair was achieved concomitantly with stapler division of the large left
atrial appendage. The patient was a 65-year-old male with severe mitral
regurgitation, paroxysmal atrial fibrillation and a large-sized atrial
appendage. Closure of the appendage was completed off-pump using a left
thoracoscopic stapler-division technique previous to right thoracoscopic
robot-assisted mitral valve repair and cryoablation. Complete closure of the
appendage was confirmed in thoracoscopic views. The bilateral thoracoscopic
technique could be preferable for the minimally invasive treatment of mitral
valvular disease and concomitant large-sized atrial appendage management.

Abstract
Left atrial appendage (LAA) has been found to be associated with the occurrence of thromboembolism in patients with nonvalvular atrial fibrillation (NVAF). Stapling exclusion of LAA during surgical ablation could be an alternative to oral anticoagulation for NVAF patients. However, its safety and efficacy have rarely been examined. Thus, in this study, we aimed to evaluate the safety and efficacy of a powered surgical stapler for LAA resection during ablation for patients with NVAF.Adult patients with NVAF undergoing stapler surgery were included in this study. LAAs of patients were cut off using a powered surgical stapler. Intraoperative transesophageal echocardiogram (TEE) was applied before and after the operation. Each patient received anticoagulant therapy for 2 months after surgery and was regularly followed up by appointment or via telephone call. Patients would undergo physical examinations, echocardiography, and 24-hour dynamic electrocardiogram in a local or in our hospital to determine whether there was a recurrence of atrial fibrillation (AF) or thromboembolism caused by AF.In total, 124 patients were included in this study (male: 88 (71.0%); mean age: 62.3 years). Blood loss was less than 100 mL in all patients with no operative complications or hospital deaths. Moreover, 119 (96.0%) follow-up data were collected, with a mean period of 27.4 months. All patients discontinued oral anticoagulants 2 months after their operation. As per our findings, AF recurred in 23 patients (18.5%), with an average of 9.1 months after surgery. No patients were diagnosed with thromboembolism related to AF.Stapling exclusion of LAA during surgical ablation could safely and completely resect the LAA. The effect of thrombus prevention was deemed satisfactory.

Thoracoscopic stand-alone appendectomy for atrial tachycardia originating from the left atrial appendage in a patient with severe left ventricular dysfunction. J Cardiol Cases 2020; 23:20-23.

Abstract
Focal atrial tachycardia (AT) originating from the left atrial appendage (LAA) is one of the rare supraventricular tachycardias and is likely to cause arrhythmia-induced heart failure. Surgical treatment could be an alternative therapy because antiarrhythmic drugs and catheter ablation therapy to focal AT originating from the distal portion of the LAA is still challenging. We report a case of successful operation of minimally invasive thoracoscopic appendectomy in a patient with poor left ventricular (LV) function due to drug-resistant AT originating from the LAA for the first time. A 51-year-old female who had AT with a poor LV function suffered from congestive heart failure. We diagnosed the ongoing AT as focal AT that originated from the distal portion of LAA by electrophysiological examination. Total thoracoscopic stand-alone appendectomy was performed safely. AT was terminated and restored to sinus rhythm immediately after appendectomy. <Learning objective: Although catheter ablation has become a first-line treatment for almost all cardiac arrhythmias, it is difficult to achieve complete cure of atrial tachycardia (AT) originating from the distal portion of left atrial appendage (LAA) because there is AT recurrence and risk of cardiac perforation and ischemic stroke. Minimally invasive thoracoscopic appendectomy is curative and can be applied safely even in patients who have poor left ventricular function due to focal AT originating from the LAA.>.

Abstract
PURPOSE A cutting stapler is a well-established instrument in many surgical fields. However, its efficacy and safety have not been proven yet in resecting a left atrial appendage (LAA) in minimally invasive cardiac surgery (MICS). METHODS A cutting stapler was used to resect the LAA in 98 consecutive patients who underwent MICS. Of these, 26 patients underwent aortic valve replacement, 72 mitral valve repair/replacement, 25 tricuspid annuloplasty, 7 closure of atrial septal defect, and 26 the Maze procedure (contains overlapping). The ascending aorta was elevated using a retractor, and a 12-mm shaft motor-driven cutting stapler was inserted through the transverse sinus. As a control group, 150 patients who underwent suture resection/closure of the LAA either from inside or outside were compared. RESULTS There was one mortality in each group. They were not related to the LAA resection/closure. In the suture group, the LAA suture was taken down in one patient because of a suspected obstruction of the circumflex artery, and two patients had re-exploration for bleeding from the LAA. In the stapler group, there was no complication related with the LAA. The rate of complication did not reach a statistical difference. CONCLUSION A cutting stapler is considered to be a useful instrument to resect the LAA in MICS.

Abstract
Atrial fibrillation (AF) patients with a previous stroke are often at a high risk of recurrent stroke and bleeding. Anticoagulation therapy in such patients is a challenging dilemma. Thoracoscopic left atrial appendage excision (LAAE) plus AF ablation is an interventional approach offered to some AF patients. We hypothesized that this approach may be suitable as a secondary stroke prevention strategy for these high-risk patients. Between January 2013 and December 2016, a total of 44 patients (26 male; mean age 65.0 ± 9.1 years) with nonvalvular AF and a previous stroke or systemic thromboembolic event were enrolled. The patients underwent thoracoscopic LAAE plus AF ablation by experienced operators and were followed up for 2 years (at 1, 3, 6, 9, and 12 months postoperatively and every 6 months thereafter). Thromboembolic and major bleeding events were recorded. Cerebral computed tomography or magnetic resonance imaging and 7-day Holter monitoring were performed annually. Mean CHA2DS2-VASc and HAS-BLED scores were 4.2 ± 1.2 and 3.3 ± 0.7, respectively. All patients discontinued oral anticoagulation therapy after the surgical intervention. One patient suffered a periprocedural transient ischemic attack, and another was diagnosed with a new ischemic stroke at 491 days after surgery. The annual rate of total thromboembolism was 2.05%. No deaths or major bleeding events were observed postoperatively. The rate of successful AF ablation with no AF recurrence was 76.3%. Transthoracoscopic LAAE plus AF ablation may be a promising approach for this high-risk population. Thromboembolism event in this secondary prevention cohort was low, even without oral anticoagulation treatment.

Abstract
Left atrial appendage (LAA) mechanical exclusion is being investigated for nonpharmacologic stroke risk reduction in selected patients with atrial fibrillation. There are multiple potential approaches in various stages of development and clinical application, each of which depends on specific cardiothoracic anatomic characteristics for optimal performance. Multiple imaging modalities can be utilized for application of this technology, with transesophageal echocardiography used for intraprocedural guidance. Cardiovascular computed tomographic angiography can act as a virtual patient avatar, allowing for the assessment of cardiac structures in the context of surrounding cardiac, coronary vascular, thoracic vascular, and visceral and skeletal anatomy, aiding preprocedural decision-making, planning, and follow-up. Although transesophageal echocardiography is used for intraprocedural guidance, computed tomographic angiography may be a useful adjunct for preprocedure assessment of LAA sizing and anatomic obstacles or contraindications to deployment, aiding in the assessment of optimal approaches. Potential approaches to LAA exclusion include endovascular occlusion, epicardial ligation, primary minimally invasive intercostal thoracotomy with thoracoscopic LAA ligation or appendectomy, and minimally invasive or open closure as part of cardiothoracic surgery for other indications. The goals of these procedures are complete isolation or exclusion of the entire appendage without leaving a residual appendage stump or residual flow with avoidance of acute or chronic damage to surrounding cardiovascular structures. The cardiovascular imager plays an important role in the preprocedural and postprocedural assessment of the patient undergoing LAA exclusion.
