Left Atrial Masses: Now You See Them, Now You Don't.

Left atrial masses are rare but clinically significant findings, which can present as diverse pathological entities, including primary tumors, thrombi, and metastases. Their diverse pathological entities contribute to a wide range of clinical manifestations, often presenting with nonspecific symptoms that pose challenges for early diagnosis. Within the realm of medicine, unique presentations emphasize the intricate interplay between the size, location, and functional impact of pathological processes. They serve as reminders to healthcare providers to approach each patient as an individual, recognizing that even seemingly minor abnormalities can have significant consequences. To illustrate this, we present two distinct cases of patients with left atrial masses, showcasing the importance of clinical suspicion and a wide knowledge base in identifying and managing these conditions effectively.

Placing a Biventricular Implantable Cardioverter Defibrillator in Major Cardiac Dextroposition (Pseudo-Dextrocardia): A Case Report and Literature Review.

We present an unusual case of a geriatric patient with right-sided cardiac displacement and rotation (Pseudo-Dextrocardia) secondary to radiation-induced pulmonary fibrosis (RIPF) after radiation for carcinoma of the right breast. This patient with heart failure with reduced ejection fraction (HFrEF) underwent cardiac resynchronization therapy with a defibrillator (CRT-D) for primary prevention of sudden cardiac death. Cannulization of the coronary sinus ostium was difficult, likely due to the significant cardiac displacement. However, after multiple attempts, it was eventually successful. The clinical manifestations, evaluation, and technical and procedural issues in this patient with an unusual anatomic variant are summarized.
