Long-Term Imaging and Clinical Outcomes of Surgical Left Atrial Appendage Occlusion With AtriClip.

Surgical left atrial appendage (LAA) occlusion with an AtriClip (AtriCure, West Chester, Ohio) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). We conducted a retrospective analysis of all patients with long-standing persistent AF who underwent hybrid convergent ablation and LAA clipping. Contrast-enhanced cardiac computed tomography was performed at 3 to 6 months after LAA clipping to assess the degree of complete closure and the residual LAA stump.

Same-day discharge following catheter ablation and venous closure with VASCADE MVP: A postmarket registry.

Introduction: Early and safe ambulation can facilitate same-day discharge (SDD) following catheter ablation, which can reduce resource utilization and healthcare costs and improve patient satisfaction. This study evaluated procedure success and safety of the VASCADE MVP venous vascular closure system in patients with atrial fibrillation (AF).

Methods: The AMBULATE SDD Registry is a two-stage series of postmarket studies in patients with paroxysmal or persistent AF undergoing catheter ablation followed by femoral venous access-site closure with VASCADE MVP.

Outcomes of cardiac surgery with left atrial appendage occlusion versus no Occlusion, direct oral Anticoagulants, and vitamin K Antagonists: A systematic review with Meta-analysis.

Surgical left atrial appendage occlusion (LAAO) is being used increasingly in the setting of atrial fibrillation but has been associated with procedural complications. This systematic review and -analysis compared the outcomes of surgical LAAO with those of no LAAO and the use of direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) using the PRISMA guidelines. A literature search was undertaken for relevant studies published between January 1, 2003, and August 15, 2021.

Impact of new-onset versus pre-existing atrial fibrillation on outcomes after transcatheter aortic valve replacement/implantation.

Patients with aortic stenosis who undergo transcatheter aortic valve replacement/transcatheter aortic valve implantation (TAVR/TAVI) experience a high incidence of pre-existing atrial fibrillation (pre-AF) and new-onset atrial fibrillation (NOAF) post-operatively. This systematic review and meta-analysis aimed to update current evidence concerning the incidence of 30-day mortality, stroke, acute kidney injury (AKI), length of stay (LOS), and early/late bleeding in patients with NOAF or pre-AF who undergo TAVR/TAVI. PubMed, Google Scholar, JSTOR, Cochrane Library, and Web of Science were searched for studies published between January 2012 and December 2020 reporting the association between NOAF/pre-AF and clinical complications after TAVR/TAVI.

Same Day versus Overnight Discharge in Patients Undergoing Ablation for Atrial Fibrillation (SODA) Study.

Patients undergoing catheter ablation for atrial fibrillation (AF) are routinely admitted for observation overnight in the hospital. With the rising incidence of AF among the population, increased volumes of procedures are placing increased demands on hospital resources. The purpose of this study was to evaluate the efficacy and safety of same day discharge in patients undergoing ablation for AF when compared to patients admitted for overnight observation.

Comparative Assessment of Transvenous versus Subcutaneous Implantable Cardioverter-defibrillator Therapy Outcomes: An Updated Systematic Review and Meta-analysis.

Background: Subcutaneous (S-ICD) and transvenous (TV-ICD) implantable cardioverter-defibrillator devices effectively reduce the incidence of sudden cardiac death in patients at a high risk of ventricular arrhythmias. This study aimed to evaluate the safe replacement of TV-ICD with S-ICD based on updated recent evidence.

Methods: We systematically searched EMBASE, JSTOR, PubMed/MEDLINE, and Cochrane Library on 30 July 2021 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Impact of statin use on heart failure mortality.

Background: There is conflicting data regarding the mortality benefit of statins in patients with heart failure. The objectives of our study were to determine whether statin therapy is associated with decreased all-cause mortality and to assess the effect of incremental duration of therapy.

Methods: We studied 10,510 consecutive patients from the Veterans Affairs health system with a diagnosis of heart failure from January 2002 through December 2006.

Thoracic aortic pseudoaneurysm following noncardiovascular surgery: a rare complication that can mimic common chest emergencies.

Pseudoaneurysm of the thoracic aorta is an extremely rare and potentially fatal condition that can mimic acute coronary syndrome, aortic dissection, or pulmonary embolism. Chest trauma and aortic surgery are the usual predisposing factors. Rarely, noncardiovascular thoracic surgeries can result in aortic pseudoaneurysm secondary to unrecognized perioperative injury.

C-Reactive Protein and The Risk of Atrial Fibrillation: A Systematic Review and Meta-Analysis.

There is increasing evidence linking C-reactive protein (CRP) and atrial fibrillation (AF). Despite the abundance of literature, confusion exists regarding this association because of inconsistent results. MEDLINE and Cochrane Controlled Trials Register databases were carefully searched through July, 2009 combining the following terms "C-reactive protein" and "atrial fibrillation".

Acute eosinophilic myocarditis mimicking myocardial infarction.

Eosinophilic myocarditis is characterized by progressive myocardial damage that results in heart failure and death. Herein, we present the case of a 54-year-old man who presented with symptoms of acute myocardial infarction. Normal coronary angiographic results and the presence of elevated levels of peripheral-blood eosinophilia prompted an endomyocardial biopsy that revealed acute eosinophilic myocarditis.

Comprehensive left atrial appendage optimization of thrombus using surface echocardiography: the CLOTS multicenter pilot trial.

Background: The aim of this study was to determine the ability to identify thrombus within the left atrial appendage (LAA) in the setting of atrial fibrillation (AF) using transthoracic echocardiography (TTE). In AF, the structure and function of the LAA has historically been evaluated using transesophageal echocardiography (TEE). The role of TTE remains undefined.

Transient midventricular ballooning: a case report and review of the literature.

Background: We describe a case of transient left midventricular ballooning in 68-year-old male patient presented with picture of acute coronary syndrome.

Case Presentation: The left ventriculogram showed mid ventricular akinesis and dilatation along with hypercontractile apex and basal segments. Follow up echocardiogram after one month showed resolution of wall motions abnormalities and normalization of the left ventricular function.

Utility of transesophageal echocardiography in identification of thrombogenic milieu in patients with atrial fibrillation (an ACUTE ancillary study).

The ACUTE trial randomly assigned patients who had atrial fibrillation (AF) of >2 days' duration to a transesophageal echocardiographically guided or a conventional strategy before cardioversion. In the 571 patients who underwent transesophageal echocardiography (TEE) in the ACUTE trial, we assessed the relative predictive value of baseline data derived by history, transthoracic echocardiography, and TEE for prediction of thrombus and adjudicated embolism (thromboembolism) as a composite end point. TEE was performed at 70 centers in 571 patients, 549 in the transesophageal echocardiographically guided group and 22 crossovers in the conventional group.

Transient left ventricular apical ballooning: a novel heart syndrome.

A novel cardiac syndrome of left ventricular apical ballooning (Takotsubo cardiomyopathy-ampulla cardiomyopathy) involves reversible left ventricular apical ballooning (during systole) of acute onset with chest pain, electrocardiographic changes, and minimal elevation of cardiac enzymes resembling acute myocardial infarction, but without evidence of myocardial ischemia or injury. Patients have no angiographic evidence of coronary artery stenosis and there is almost always a complete recovery of left ventricular function in days to weeks. The precise etiologic basic of this syndrome is not clear but most likely it is a non-ischemic, metabolic syndrome caused by stress-induced activation of the cardiac adrenoceptors in absence of ischemia and reperfusion.

Constrictive pericarditis: etiology and cause-specific survival after pericardiectomy.

Objectives: We sought to determine the association of etiology of constrictive pericarditis (CP), pericardial calcification (CA), and other clinical variables with long-term survival after pericardiectomy.

Background: Constrictive pericarditis is the result of a spectrum of primary cardiac and noncardiac conditions. Few data exist on the cause-specific survival after pericardiectomy.
