Metastasis of cervical cancer to the heart is rare. Cervical carcinoma typically spreads to the lungs, liver, bones, and lymph nodes via hematogenous, lymphatic, transvenous, or direct extension. Cardiac metastasis from cervical carcinoma is uncommon and portends a dismal prognosis, with mean survival under six months post-diagnosis. A high index of suspicion and multimodal imaging is imperative for prompt diagnosis and improved outcomes in these patients. Here, we report a rare case where a 41-year-old African American female with stage IIIB cervical squamous cell carcinoma (SCC) presented with exertional dyspnea and chest pain concerning pulmonary embolism (PE). Computed tomography angiography showed no PE but revealed a right ventricular (RV) mass and diffuse pulmonary nodules. Echocardiography suggested an RV tumor versus a thrombus. Cardiac magnetic resonance imaging demonstrated a large RV infiltrative mass favoring metastasis over thrombus. A biopsy of one of the pulmonary nodules confirmed metastatic SCC. Despite treatment, the prognosis was poor.

Aortic stenosis (AS) is the most prevalent degenerative valvular disease in western countries. Transthoracic echocardiography (TTE) is considered, nowadays, to be the main imaging technique for the work-up of AS due to high availability, safety, low cost, and excellent capacity to evaluate aortic valve (AV) morphology and function. Despite the diagnosis of AS being considered straightforward for a very long time, based on high gradients and reduced aortic valve area (AVA), many patients with AS represent a real dilemma for cardiologist. On the one hand, the acoustic window may be inadequate and the TTE limited in some cases. On the other hand, a growing body of evidence shows that patients with low gradients (due to systolic dysfunction, concentric hypertrophy or coexistence of another valve disease such as mitral stenosis or regurgitation) may develop severe AS (low-flow low-gradient severe AS) with a similar or even worse prognosis. The use of complementary imaging techniques such as transesophageal echocardiography (TEE), multidetector computed tomography (MDTC), or cardiac magnetic resonance (CMR) plays a key role in such scenarios. The aim of this review is to summarize the diagnostic challenges associated with patients with AS and the advantages of a comprehensive multimodality cardiac imaging (MCI) approach to reach a precise grading of the disease, a crucial factor to warrant an adequate management of patients.

Giant coronary artery aneurysm (GCA) is a rare disease afflicting 0.2% of the population. It is primarily attributed to atherosclerosis in adults and Kawasaki disease in children. Other uncommon etiologies include Takayasu arteritis and post-percutaneous coronary intervention.1,2 GCA lacks a universally accepted definition, with proposed criteria including a diameter exceeding 2 cm, 5 cm, or four times the normal vessel size.3 While the majority of GCAs are asymptomatic, a subset of patients present with angina, myocardial infarction from embolization or compression, heart failure due to fistula formation, or even sudden death.1 We report a case of an adult harboring a GCA involving the right coronary artery.

UNASSIGNED: Primary cardiac lymphoma (PCL) is rare and its presentation can be variable. Thorough workup of suspected PCL or other cardiac tumours typically incorporates a range of imaging techniques and laboratory investigations but ultimately diagnosis is confirmed by histological analysis of myocardial tissue.
UNASSIGNED: An 80-year-old Caucasian female presented with complete heart block and symptomatic cardiac tamponade. A pericardiocentesis was performed and a dual-chamber permanent pacemaker was implanted for the management of her complete heart block. Subsequently, a right atrial mass was discovered on imaging and the patient underwent endomyocardial biopsy of the mass. Histological analysis of the sample confirmed a primary cardiac lymphoma. The patient opted to forgo treatment with chemotherapy and died from her disease 1 month later.
UNASSIGNED: Cardiac arrhythmias can occur in PCL due to infiltration of conduction pathways. Characterization of cardiac masses on various imaging modalities and laboratory tests guides diagnosis. Tissue diagnosis is required to confirm PCL. The location of a cardiac mass may present technical challenges when undertaking a biopsy, so the best approach to tissue sampling should be considered on an individual basis. Without treatment survival is less than one month but with modern chemoimmunotherapy five-year survival may exceed 50%.

Atrial fibrillation is one of the most common cardiac arrhythmias, classically presenting with an \"irregularly irregular\" rhythm with or without chest pain, palpitations, shortness of breath, lightheadedness, or fatigue. The maze procedure is an open-heart operation that creates a carefully designed maze of incisions and ablations in the atrial myocardium. Although it is a common procedure, serious complications may happen. Herein, we report on a 76-year-old man who presented with chest pain and atrial fibrillation and was found to have multi-vessel disease on a coronary angiogram. He underwent coronary artery bypass and the COX-maze procedure, which was complicated by a massive thrombosis in the atria and the superior vena cava following the ablation line, secondary to heparin-induced thrombocytopenia, which is extremely rare. The central focus of this paper is to present this rare complication to stress the importance of rigorous follow-up and anticoagulation therapy in patients undergoing the maze procedure. To our knowledge, we are the first to report such a rare case of diffuse large atrial thrombi triggered by heparin-induced thrombocytopenia (HIT) type II after a COX-maze procedure.

Membranous interventricular septal (MIVS) aneurysm is a rare often asymptomatic, accidentally discovered congenital anomaly, which might be complicated with right ventricular obstruction, rupture, thromboembolism, and conduction abnormalities.

Mechanical prosthetic valve thrombosis (PVT) is a serious condition that is associated with various life-threatening complications. The utilization of multimodality imaging techniques is critical in identifying this etiology. Its management is complex and often requires repeat surgical valve replacements. Our report describes the case of a 48-year-old female who presented with mechanical mitral valve thrombosis in the setting of subtherapeutic anticoagulation. Due to her complex surgical history, nonsurgical therapeutic options were initially pursued for management. Through shared decision-making and after exhaustion of other alternatives, she was maintained on optimized medical therapy and was scheduled for repeat elective surgery. After compliance with medical therapy and close monitoring, she improved significantly, and her underlying pathology completely resolved, eliminating the need for surgery. This report indicates that the management of mechanical prosthetic valve thrombosis should be individualized and emphasizes the importance of involving a multidisciplinary team of medical and surgical professionals to achieve the best clinical outcomes.

Sarcoidosis is a rare cause of cardiomyopathy that can easily be confused for acute heart failure when pulmonary manifestations are absent. We present the case of a 41-year-old female presenting with dyspnea found to have ventricular arrhythmia on arrival at the emergency department. Cardiac magnetic resonance and computed tomography of the chest with contrast were performed, confirming the systemic sarcoidosis diagnosis with cardiac involvement.

Prosthetic valve endocarditis is a devastating infection with a challenging diagnosis and management. Despite advances in its diagnostic modalities, medical, and surgical interventions, prosthetic valve endocarditis still carries high morbidity and mortality rates. Here, we report a case of prosthetic aortic valve endocarditis that progressed to involve the paravalvular space and the importance of multimodality cardiac imaging in the early detection of paravalvular complications.
