Cardiac myxoma is a benign cardiac tumor. A rare phenomenon associated with cardiac tumors is the embolization of the myxomatous material into the coronary arteries, leading to myocardial infarction. This typically requires surgical excision of the tumor to prevent recurrence. Early diagnosis with the help of both transthoracic and transesophageal echocardiography is vital in managing these patients. Here, we present a case of a 49-year-old male patient who initially presented with chest pain and non-ST segment elevation myocardial infarction (NSTEMI) and subsequently newly diagnosed cardiomyopathy. Upon further cardiac evaluation, he was found to have a large left atrial myxoma with non-obstructive coronary artery disease. It was suspected that the etiology for NSTEMI and subsequent newly diagnosed cardiomyopathy was due to myxomatous embolization into the coronary arteries; ischemic cardiomyopathy was excluded by definition. The patient subsequently underwent successful surgical excision of the left atrial myxoma.

A 71-year-old man with a history of atrial fibrillation presented to the emergency department with sudden unconsciousness after finishing lunch. Just 4 weeks ago, the patient underwent radiofrequency ablation for atrial fibrillation and regularly took rivaroxaban for anticoagulant therapy. According to the medical history, the patient suffered recurrent chest tightness and heartburn after radiofrequency ablation without other discomforts.

Medical image-based computational fluid dynamics (CFD) is a valuable tool for studying cardiovascular hemodynamics and its role in vascular pathologies. However, patient-specific flow rate measurements are rare. As a remedy, individual flow rates are typically estimated using anatomical features.

Purpose: In patients with repaired tetralogy of Fallot, transcatheter or surgical pulmonary valve replacement is recommended. However, it is not clear whether pulmonary valve replacement preserves systolic and diastolic functions of both ventricles. The aim of the study is to investigate the impact of transcatheter pulmonary valve replacement on atrial and ventricular myocardial strain changes by feature-tracking cardiac magnetic resonance imaging.

Background: Although rare, embolization of left atrial appendage occlusion (LAAO) devices carries a significant morbidity and mortality burden.
Case Summary: An asymptomatic 77-year-old woman with inability to tolerate anticoagulation due to gastrointestinal bleeding presented for 45-day transesophageal echocardiography following LAAO with a Watchman device, which demonstrated incidental device migration to the left ventricular outflow tract (LVOT). Percutaneous extraction was performed using a novel technique with rat tooth/alligator forceps to successfully retrieve the Watchman from the LVOT using a transaortic approach.

Background And Aims: Advanced technologies such as charge density mapping (CDM) show promise in guiding adjuvant ablation in patients with persistent atrial fibrillation (AF); however, their limited availability restricts widespread adoption. We sought to determine whether regions of the left atrium containing CDM-identified pivoting and rotational propagation patterns during AF could also be reliably identified using more conventional contact mapping techniques.
Methods: Twenty-two patients undergoing de novo ablation of persistent AF underwent both CDM and electroanatomic voltage mapping during AF and sinus rhythm with multiple pacing protocols.
