Coronary Orbital Atherectomy Through Newly Deployed Left Main Coronary Stent.

Percutaneous coronary intervention (PCI) in complex, calcified coronary lesions can be assisted with orbital atherectomy (OA). OA is generally avoided when there are lesions amendable to OA distal to a newly deployed stent due to the risk of device-stent interaction, burr entrapment, and stent avulsion. We present a case documenting the successful passage of an OA system through a recently deployed left main stent to prepare a chronically occluded left anterior descending for PCI.

Left Atrial Appendage Closure Outcomes in Patients With Cancer at a Single Tertiary Center.

Atrial fibrillation is the most common arrhythmia in patients with underlying malignancy. Patients with cancer have a higher risk of bleeding, and at the same time, carry an elevated risk of thromboembolism related to the hypercoagulable state, type of cancer, and anticancer treatment, rendering safe anticoagulation challenging in this population. Left atrial appendage closure is an alternative treatment option in patients with atrial fibrillation and high bleeding risk; however, the data on patients with cancer are limited.

Delayed Pericardial Effusion Following Left Atrial Appendage Closure: A 5-Year Single-Center Experience.

Background: Though uncommon, pericardial effusion and cardiac tamponade are serious complications of left atrial appendage closure (LAAC). There are few data related to delayed pericardial effusions from this procedure.

Methods: This is a single-center prospective analysis of 369 patients who underwent LAAC from December 2016 to March 2022 at a large teaching hospital.

Predictors of successful same-day discharge and 1-year outcomes after left atrial appendage closure.

Background: Same-day discharge (SDD) following left atrial appendage closure (LAAC) is increasingly common but predictors of successful SDD and 1-year clinical outcomes have not been described.

Objective: The purpose of this study was to explore predictors of successful SDD and report 1-year outcomes in patients undergoing LAAC with SDD.

Methods: A prospective analysis was performed over a 20-month period of 225 consecutive patients that underwent LAAC in a large, academic hospital.

Novel computed tomography angiography-based sizing methodology for WATCHMAN FLX device in left atrial appendage closure.

Background: While there is recent data suggesting an advantage of computed tomography angiography (CTA) over transesophageal echocardiography (TEE) for preprocedural left atrial appendage closure (LAAC) planning, there is limited published experience for sizing strategies. Device sizing for LAAC may be challenging and noninvasive algorithms that improve this selection process are warranted.

Objectives: We sought to evaluate the safety and the feasibility for the implementation of a novel CTA-based sizing methodology for WATCHMAN™ FLX device in a series of patients undergoing LAAC using the TruPlan™ software package.

Atrial flutter mimicking ST-elevation myocardial infarction.

A 12 lead electrocardiogram provides an important diagnostic tool for atrial flutter recognition. However, rarely, atrial flutter waves can cause diagnostic challenges by producing ST segment abnormalities mimicking ST segment elevation and result in unnecessary workup and treatment. ​.

Chronic Aortocaval Fistula Presenting as Right Heart Failure: A Case Report and Review of Literature.

Iatrogenic aortocaval fistula (ACF) is an infrequent cause of heart failure. A 65-year-old man presented to the cardiology clinic eight months after an open abdominal aortic aneurysm (AAA) repair. He developed predominantly right-sided cardiac failure after surgery, with minimal response to guideline-directed medical therapy.

Supraventricular tachycardia with the use of phentermine: case report and review of literature.

: A 34-year-old woman with no significant past medical history presented to the hospital with sudden onset of palpitations with associated dyspnea and chest discomfort. She denied any similar previous episodes. Initial electrocardiogram (EKG) was consistent with a short R-P interval supraventricular tachycardia (SVT).

Escitalopram Induced Torsade de Pointes and Cardiac Arrest in a Patient With Surgically Treated Mitral Valve Prolapse.

A 54-year-old female, with a history of prosthetic mitral valve replacement due to mitral valve prolapse one year prior, was admitted after suffering a cardiopulmonary arrest. Her initial rhythm demonstrated Torsade de Pointes with the initial electrocardiogram (ECG) showing a prolonged QT interval. Laboratory test results were normal including potassium and magnesium serum levels, and imaging did not show significant abnormalities.
