Intramyocardial lipomas are rare benign cardiac tumors that often present a diagnostic dilemma due to their nonspecific clinical and imaging features on initial evaluation. We report the case of a 40-year-old asymptomatic male who presented with a large intramyocardial lipoma arising from the basal inferior wall of the left ventricle. Initial transthoracic echocardiography revealed an echogenic mass in the region of the left ventricle basal septum but was insufficient for definite characterization. Cross-sectional imaging, including computed tomography (CT) and cardiac magnetic resonance imaging (MRI), demonstrated a homogeneous fat-density mass consistent with lipoma. This case highlights the pivotal role of multimodality imaging in accurately characterizing a rare primary cardiac tumor.

We report a case of a 49-year-old female who presented with atypical chest pain. An electrocardiogram-gated coronary computed tomography angiography revealed the absence of the left main coronary artery segment with direct origin of the left anterior descending artery and the left circumflex artery from the left coronary sinus having separate ostia. The case highlights a rare anomaly of coronary artery origin with procedural implications.

This 11-minute video aims at improving skills for the structural assessment of sinus venosus defects using 2-dimensional transthoracic echocardiography (TTE) to increase the ability to diagnose-or rule out-the different types of interatrial communications. Of the five types of lesions, this video focuses on superior and inferior sinus venosus defects. This is the second video in our MicroLearning Video Series, designed to help a target audience of sonographers, general cardiologists, general practitioners who want to gain knowledge on fundamental cardiology, and technicians.

This 62-minute webcast features a conversation about "Heart Transplantation"-the focus of Issue 21.3. Led by the issue's editor, the discussion engages the authors on emerging themes and lessons learned while researching and writing the articles. View the video at https://vimeo.com/event/5134934.

This 58-minute webcast features a conversation about "Coronary Artery Disease"-the focus of Issue 21.4.

A 19-year-old man with chest pain underwent cardiac magnetic resonance imaging (MRI), which identified a multilobulated cyst with internal septations located in the lateral left ventricular myocardium, consistent with a hydatid cyst. High-resolution cine and late gadolinium enhancement imaging demonstrated its structure and myocardial involvement. This case shows the capability of cardiac MRI in diagnosing rare cardiopericardial hydatid disease.

We report the case of a 79-year-old male with atypical chest pain where electrocardiogram-gated coronary computed tomography angiography (CTA) demonstrated a split right coronary artery with an intra-atrial course of the posterior trunk. This case highlights the clinical implications of the rare anomaly and the importance of coronary CTA in detecting this unusual variant, which will be missed even on invasive coronary angiography.

We report a case of a 27-year-old female with supracardiac total anomalous pulmonary venous connection, where computed tomography angiography demonstrated a thin eccentric membranous web at the junction of the common chamber and ascending vertical vein with aneurysmal dilatation of the vertical vein distal to it. The development of the vertical vein aneurysm could possibly be attributed to the presence of turbulent flow within the vertical vein, distal to the site of stenosis caused by the membranous web.

Aortic perforation is a rare and potentially fatal complication during percutaneous coronary intervention (PCI). This Interactive CME Case presents the case of a 47-year-old man who developed cardiac tamponade secondary to iatrogenic aortic perforation during PCI-a true nightmare.

We report a case of a 50-year-old male presenting with class III angina on exertion, where an electrocardiogram-gated coronary computed tomography angiography (CCTA) demonstrated the unique coexistence of a type IV dual left anterior descending artery and a split right coronary artery. This case underscores the importance of CCTA in accurately delineating rare coronary artery anatomical variants to avoid both a misdiagnosis and the risk of potential catastrophic outcomes during interventional or surgical procedures.
