Background: Early experience with transcatheter mitral valve replacement (TMVR) highlighted several investigational challenges related to this novel therapy. Conclusive randomised clinical trials in the field may, therefore, be years ahead. In the interim, contemporary outcomes of isolated surgical bioprosthetic mitral valve replacement (MVR) can be used as a benchmark for the emerging TMVR therapies. Methods: We used the nationwide inpatient sample to examine recent trends and outcomes of surgical bioprosthetic MVR for mitral regurgitation (isolated and combined)...

An increasing number of detection tools are available and several detection strategies have been described to pursue the diagnosis of atrial fibrillation to prevent ischemic stroke. Monitoring tools include standard electrocardiography, snapshot single-lead recordings with professional or personal devices (e.g. smartphone-based), Holter monitor, external devices with long-term recording capabilities, and cardiac implantable electronic devices, including pacemakers, implantable cardioverter defibrillators and insertable cardiac monitors...

A 56-year-old female presented to the emergency department with evolving cardiac tamponade after receiving alteplase for acute ischemic stroke. This is the first case report of cardiac tamponade from thrombolytics in the setting of recent pacemaker placement. Point-of-care ultrasound was used to make the diagnosis quickly and expedite the patient to the operating room where a pericardial window was performed.

BACKGROUND: The incidence of patients with previous history of coronary artery bypass grafting (CABG) presenting for aortic valvular replacement has been consistently on the rise. Repeat sternotomy for surgical aortic valve replacement (SAVR) carries an inherent risk of morbidity and mortality when compared to Transcatheter aortic valve replacement (TAVR). METHODS: The Nationwide inpatient sample (NIS) from 2012 to 2014 was queried using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9-CM) codes to identify all patients ≥ 18 years with prior CABG who underwent TAVR (35...

PURPOSE: Subclinical atrial fibrillation (AF) was found in a large number of pacemaker patients. It is not certain whether there is a similar risk/benefit ratio for oral anticoagulation in patients with subclinical AF compared to patients with similar risk profiles and clinically diagnosed AF. Given the weakness of clinical evidence for oral anticoagulation in patients with device-detected subclinical AF, specific recommendations in most guidelines for this population are scarce and rarely similar...

Lymph formation and propulsion rely on an extrinsic mechanism based on the forces that surrounding tissues exert upon the vessel wall and lumen and an intrinsic mechanism based on spontaneous, rhythmic contractions of the lymphatic muscle layer of collecting vessels. The two spontaneous pacemakers described in literature involve chloride-dependent depolarizations (STDs) and If -like currents, both giving rise to a variable contraction frequency (fc ) of lymphatic vessels functional units (lymphangions). Several stimuli have been shown to modulate fc , such as temperature, shear stress, and several tissue chemical modulators (prostaglandins, norepinephrine, acetylcholine, substance P, and others)...

BACKGROUND: The transapical approach has been utilized in adult HCM patients with either midventricular obstruction or a small LV cavity; however, there are little data on its use in children. METHODS: We retrospectively reviewed all patients (age <21 years) with HCM who underwent a transapical myectomy from January 2002 to December 2016. Indication for surgery was midventricular obstruction in 19/23 (83%) and small LV cavity in 4 (17%). Preoperative symptoms included: dyspnea (96%), chest pain (65%), presyncope (61%), and syncope (35%)...

BACKGROUND: The Heart Rhythm Society consensus statement arbitrarily defines atrial fibrillation (AF) ablation failure as any episode ≥30 seconds. However, if brief AF events are not correlated to longer events, the rationale for this end point is questionable. We determined the impact of AF episode duration threshold on AF incidence and burden. METHODS: Patients with a pacemaker in a prospective registry with device-detected AF and follow-up >30 days were analyzed...

BACKGROUND: Chronic anticoagulation is recommended for atrial fibrillation (AF) patients with thromboembolic risk factors regardless of AF duration/frequency. Continuous rhythm assessment with pacemakers (PMs)/implantable cardioverter-defibrillators (ICDs) and use of direct-acting oral anticoagulants (DOACs) may allow anticoagulation only around AF episodes, reducing bleeding without increasing thromboembolic risk. OBJECTIVE: The purpose of this study was to evaluate the feasibility/safety of intermittent DOAC use guided by continuous remote AF monitoring via dual-chamber PMs or ICDs...

Transcatheter aortic valve implantation (TAVI) has evolved globally, yet its evolution and performance across the Canadian landscape have yet to be formally assessed. Patients captured within the early Canadian TAVI experience with a balloon-expanding valve (n = 339; 2005 to 2009) and those enrolled in the Canadian SOURCE XT registry (n = 415; 2012 to 2015) were systematically compared with respect to baseline clinical, echocardiographic, and procedural characteristics. Valve-related and clinical outcomes were compared across the 2 time periods according to standardized definitions...

Balloon predilation (BPD) has been an integral part of transcatheter aortic valve implantation (TAVI) since inception. We sought to investigate the effect of avoiding BPD on outcomes of TAVI across different valve types. Articles were included if outcomes of TAVI without BPD were reported. Pooled meta-analysis used a random effects model and reported odds ratios (ORs). Twenty-one studies with 10,752 patients were pooled for analysis. Age and gender were well matched between NoBPD and BPD groups. There was no difference in mortality, stroke, bleeding, and acute kidney injury...

Objective: The mitral valve may be accessed directly through the left atrium but visualisation can sometimes be challenging. A trans-septal interatrial approach provides better exposure and easy access for concomitant tricuspid procedures especially in difficult cases. This retrospective study evaluates the safety and effectiveness of the extended vertical trans-septal approach (EVTSA) for routine mitral valve exposure. Method: 1017 consecutive patients undergoing an isolated primary mitral valve procedure (repair/replacement) through a median sternotomy were retrospectively studied between 2000 and 2015...
