Comparison of Figure-of-Eight Suture and Perclose ProGlide Suture-Mediated Closure in Large Bore Venous Access Hemostasis: A Randomized Controlled Trial.

Suture-mediated closure device and Figure-of-Eight suture are commonly used to achieve hemostasis after use of large bore venous access. Although both methods of closure are commonly used in clinical practice, a head-to-head comparison in a controlled setting has not been performed. Patients presenting to a single center for elective left atrial appendage occlusion or transcatheter edge-to-edge mitral valve repair were randomized to large bore venous closure using the Perclose ProGlide suture-based closure or a Figure-of-Eight suture closure.

In these endemic countries there is limited published literature on the clinical profile and severity of Plasmodium vivax malaria in children. We highlight the clinical presentations and severity of malaria in children belonging to Uttar Pradesh, North India Methods: This observational study was conducted in a tertiary care hospital, in Moradabad, western Uttar Pradesh, India.

Coronary Obstruction From TAVR in Native Aortic Stenosis: Development and Validation of Multivariate Prediction Model.

Background: Transcatheter aortic valve replacement (TAVR)-related coronary artery obstruction prediction remains unsatisfactory despite high mortality and novel preventive therapies.

Objectives: This study sought to develop a predictive model for TAVR-related coronary obstruction in native aortic stenosis.

Methods: Preprocedure computed tomography and fluoroscopy images of patients in whom TAVR caused coronary artery obstruction were collected.

Outcomes of the roll-in cohort of the Amulet IDE trial of left atrial appendage occlusion.

Background: Left atrial appendage (LAA) occlusion is an alternative therapy to oral anticoagulants to reduce stroke risk in patients with nonvalvular atrial fibrillation (NVAF). The Amulet IDE trial compared the Amplatzer™ Amulet™ occluder (Abbott) with the Watchman™ 2.5 device (Boston Scientific) for LAA occlusion in patients with NVAF.

Transvalvular Pressure Gradients and All-Cause Mortality Following TAVR: A Multicenter Echocardiographic and Invasive Registry.

Background: Low ejection fraction (EF) and low flow as determined by an echocardiographic stroke volume index (SVi) <35 mL/m are associated with low transvalvular gradients and increased mortality in both severe aortic stenosis (AS) and post-transcatheter aortic valve replacement (TAVR). Absence of an elevated echocardiographic transaortic gradient post-TAVR is considered a marker of procedural success despite the absence of data on its impact on mortality.

Objectives: The authors sought to examine the association of invasive and echocardiographic gradients post-TAVR with all-cause mortality in relation to flow and EF.

In-hospital outcomes of transesophageal versus intracardiac echocardiography guided left atrial appendage closure.

Background: Transesophageal echocardiogram (TEE) is the preferred imaging modality to guide transcatheter left atrial appendage closure (LAAC). Intracardiac echocardiography (ICE) has evolved as a less invasive alternative to TEE. Several observational studies have shown similar success rates and perioperative complications between TEE and ICE for LAAC.

Incidence of Early Atrial Fibrillation After Transcatheter versus Surgical Aortic Valve Replacement: A Meta-Analysis of Randomized Controlled Trials.

Background: Post-operative atrial fibrillation (POAF) is common after aortic valve replacement (AVR) and is associated with worse outcomes. We performed a meta-analysis of randomized controlled trials comparing Surgical Aortic Valve Replacement (SAVR) and Transcatheter Aortic Valve Replacement (TAVR) for incidence of POAF at 30 days.

Methods: We searched databases from 1/1/1990 to 1/1/2020 for randomized studies comparing TAVR and SAVR.

A Rare Iatrogenic Trio: Pneumopericardium, Pneumoperitoneum, and Pericarditis.

We present a rare case of iatrogenic pneumopericardium, pneumoperitoneum, and pericarditis after emergency pericardiocentesis for pericardial tamponade. The patient had profound bowel distention at the time of the procedure that led to iatrogenic pericardioperitoneal fistula formation along with transverse colon perforation, which manifested later after pericardial drain removal. This condition required repeat pericardiocentesis, laparoscopic colon repair, a long course of antibiotics, and an eventual pericardial window.

Feasibility of Transcatheter Mitral Valve Repair for Non-A2P2 Mitral Regurgitation.

MitraClip is approved for treatment of both degenerative and functional mitral regurgitation (MR). The landmark trials for this device included only patients with A2P2 location of MR. Initial commercial experience showed A2P2 location was associated with higher technical success as compared with non-A2P2 location.

Amplatzer Amulet Left Atrial Appendage Occluder Versus Watchman Device for Stroke Prophylaxis (Amulet IDE): A Randomized, Controlled Trial.

Background: Percutaneous closure of the left atrial appendage (LAA) is an alternative to chronic oral anticoagulation to reduce stroke risk in patients with nonvalvular atrial fibrillation. The Amulet IDE trial (Amplatzer Amulet Left Atrial Appendage Occluder IDE Trial) was designed to evaluate the safety and effectiveness of the dual-seal mechanism of the Amulet LAA occluder compared with the Watchman device.

Methods: Patients with nonvalvular atrial fibrillation at increased risk of stroke were randomly assigned (1:1) to undergo percutaneous implantation of a LAA occluder with the Amulet occluder or Watchman device.

Enhancing occupational safety in the X-ray laboratory.

Despite more than 80% of interventional operators reporting one or more orthopedic injuries attributed to the X-ray laboratory, there has been limited adoption of various strategies and equipment to minimize these injuries. A comprehensive review of these methods to reduce musculoskeletal strain is lacking in the current literature, and is essential in order to ensure a long, healthy, and productive interventional career.

Transcatheter Closure of Persistent Left Superior Vena Cava Draining to Pulmonary Vein: A Rare Entity.

We describe a patient with recurrent embolic strokes who was found to have a persistent left superior vena cava draining into a pulmonary vein. Transcatheter placement of a vascular plug resulted in successful occlusion of the superior vena cava. Repeat bubble study on follow-up imaging was negative for a right-to-left shunt.

Machine learning-based heart disease prediction system for Indian population: An exploratory study done in South India.
