The Simplified Extraction of Atrial Tumor With Targeted Loop Electricity (SEATTLE) Procedure.

The removal of intramyocardial masses has long been thought of as a surgical procedure and is generally reserved for patients with obstructive symptoms when the mass is thought to be benign. Thus, many patients who are incidentally diagnosed with intracardiac masses are either subjected to protracted follow-up with serial imaging awaiting tumor growth before surgical excision is ultimately offered. We report a novel procedure in which a 54-year-old man with an atrial myxoma underwent successful percutaneous resection using electrosurgery followed by removal with a novel endovascular retrieval system. This approach provides an alternative to either surgical excision or watchful waiting in patients with small- to medium-sized intracardiac tumors. (Level of Difficulty: Advanced.).

Pregnancy in the Cardiac Catheterization Laboratory: A Safe and Feasible Endeavor.

Concerns over radiation exposure are ubiquitous to all interventional cardiologists; however, fear of exposure during childbearing years disproportionately deters women from entering the field. This review summarizes the available data on occupational radiation exposure during pregnancy with an emphasis on radiation quantification, the impact of exposure at various stages of fetal development, societal recommendations for safe levels of exposure during gestation, threshold levels necessary to induce fetal harm, and safe practices for the pregnant interventionalist. Reconciling the available information, we conclude that pregnancy in the cardiac catheterization laboratory is both safe and feasible. This review also highlights new technologies that may augment standard radiation safety techniques and are of particular interest to the pregnant interventional cardiologist. Finally, we propose steps to improve female representation in this field, underscoring the importance of a sex-balanced workforce.

Arrhythmias in Cardiac Sarcoidosis Bench to Bedside: A Case-Based Review.

Cardiac sarcoidosis is a component of an often multiorgan granulomatous disease of still uncertain cause. It is being recognized with increasing frequency, mainly as the result of heightened awareness and new diagnostic tests, specifically cardiac magnetic resonance imaging and 18F-fluorodeoxyglucose positron emission tomography scans. The purpose of this case-based review is to highlight the potentially life-saving importance of making the early diagnosis of cardiac sarcoidosis using these new tools and to provide a framework for the optimal care of patients with this disease. We will review disease mechanisms as currently understood, associated arrhythmias including conduction abnormalities, and atrial and ventricular tachyarrhythmias, guideline-directed diagnostic criteria, screening of patients with extracardiac sarcoidosis, and the use of pacemakers and defibrillators in this setting. Treatment options, including those related to heart failure, and those which may help clarify disease mechanisms are included.

Acute Increase in Deaths Among Patients With Adult Congenital Heart Disease During COVID-19: Single-Center Experience.

Fear of acquiring severe acute respiratory syndrome coronavirus-2 infection is a major contributor to underutilization of the health care system during the current pandemic. In this report, we describe 4 cases of unexpected deaths that occurred within a short time period in patients with adult congenital heart disease without warning symptoms.

Shading operators from the Gray: Are novel radiation barriers or changing physician behaviors the best next step?

Lead barriers to reduce operator radiation exposure in the catheterization laboratory are effective. This study of a novel vertical radiation shield suggests significant reduction in operator radiation exposure when used in addition to standard protection methods. Although additional barriers may help reduce radiation exposure, further education and training of operators in radiation safety may be as effective and perhaps more effective than additional barriers.

Constrictive Pericarditis After Lung Transplantation.

As a rare complication after lung transplant, cardiac constriction should not be missed. Physical exam, echocardiography, and catheterization are essential for diagnosis A 65-year-old man with previous coronary artery disease and idiopathic pulmonary fibrosis underwent bilateral lung transplant and subsequently presented for progressive dyspnea and volume overload. Cardiac imaging and cardiac catheterization confirmed constriction, and complete pericardiectomy was performed. The patient had rapid resolution of heart failure symptoms. Pericardial constriction is a rare complication following lung transplant, and we provide a review of the literature and discussion of potential contributing factors.

Infective Endocarditis: Update on Epidemiology, Outcomes, and Management.

PURPOSE OF REVIEW: Infective endocarditis remains a highly mortal disease, yet the diagnosis often is missed or made only late in the disease course. The spectrum of patients presenting with endocarditis is shifting with different risk factors, predisposing patient characteristics, and treatment recommendations than in the past. This review addresses changes in the epidemiology of infective endocarditis, along with current diagnostic imaging modalities, treatment recommendations, and mortality trends. RECENT FINDINGS: Risk factors for endocarditis now include the growing population of adults with congenital heart disease and patients with frequent healthcare contact for other comorbidities, as well as patients who are hemodialysed and immunocompromised or use intravenous drugs. Although transthoracic and transesophageal echocardiography are essential for diagnosis, additional testing (nuclear, computed tomographic, and magnetic resonance imaging) is helpful in selected patients. Early surgical management, even in high-risk patients, has a mortality benefit because eradication of infection with antibiotics alone is difficult and because valve destruction often results in hemodynamic compromise. As part of a broad differential diagnosis, clinicians should consider the diagnosis of endocarditis in patients with risk factors, even when the clinical presentation is nonspecific. Blood cultures and echocardiography are the first steps for diagnosis. Other imaging modalities can enhance diagnosis, particularly in patients with intracardiac devices or prosthetic material. Evidence from observational studies support early surgical intervention to reduce morbidity and mortality from this lethal condition.
