Left ventricular chordae tendinae myxoma causing stroke: A rare finding.

ABSTRACT: A 52-year-old woman presented with dysarthria and right-sided weakness in her upper and lower extremities prompting thrombolytic therapy with mild resolution of symptoms. Further work-up revealed (the source) a left ventricular myxoma on the chordae tendinae of the posterior medial papillary muscle, confirmed with transesophageal echocardiography and pathology. Herein, we present a rare case of embolic stroke from a myxoma originating on the chordae tendinae. To the best of our knowledge, the literature on the location and presentation of this tumor as seen in our patient is sparse in contemporary findings.

Left Ventricular Myxoma Causing Posterior Circulation Stroke.

Project description:Myxoma is a cardiac tumor most commonly found in the left atrium, presenting most frequently with dyspnea, chest pain, and constitutional symptoms. Hereby, we are presenting a rare case of cardiac myxoma originating from the left ventricle, presenting with an ischemic stroke in a young individual. He underwent surgical excision of the mass.

Left ventricular mass: myxoma or thrombus?

Project description:Patient with embolic episode should always be evaluated for cardiac mass. Mass in left ventricular can be a myxoma or thrombus even in a normal functioning heart. In either case, mobile mass with embolic potential should be surgically resected.

A Rare Case of Left Atrial Myxoma Vascularity Causing Acquired Coronary Cameral Fistula: Role of Transesophageal Echocardiography.

Project description:Left atrial myxoma is the common benign tumor of heart. Coronary arteries may supply these tumor. Considering the vascular nature of the tumor, acquired coronary cameral fistula(CCF) can be a possibility postexcision of the left atrial myxoma. Here, we discuss a case of 53-year-old female patient, who developed acquired CCF, following excision of the tumor and the role of transesophageal echocardiography intraoperatively in diagnosis.

Left atrial myxoma causing near‐total mitral valve obstruction

Project description:Abstract Cardiac myxomas are the most common primary cardiac tumors in adults, with the left atrium being the most frequently affected. Echocardiography is the diagnostic modality of choice. The most effective treatment for cardiac myxomas is surgical excision. We present a clinical video of a large left atrial myxoma causing mitral valve obstruction, highlighting the importance of echocardiography as a diagnostic modality to facilitate referral to a tertiary center.

Cystic cardiac myxoma: a rare variant of cardiac myxoma in a woman with acute stroke.

Project description:BackgroundCardiac myxomas are the most common primary benign tumors of the heart usually presenting as an oval mass attached to the interatrial septum. Mild heterogenous enhancement is typically seen upon contrast administration. Myxomas are benign, however can present with embolic episodes necessitating prompt diagnosis and treatment.Case presentationA middle-aged woman presenting with acute ischemic stroke was detected to have a complex cystic mass in the left atrium on echocardiography. Further evaluation with cardiac magnetic resonance imaging narrowed a differential diagnosis to hemangioma, hemangioendothelioma, sarcoma, hydatid cysts, bronchogenic cysts, and cystic variant of cardiac myxoma. CTA demonstrated arterial supply from the left circumflex artery supplying the lesion. Following surgical excision, histopathology analysis suggested a cystic cardiac myxoma with secondary degeneration.ConclusionCystic masses in the heart are challenging to diagnose due to similar imaging characteristics, and misdiagnosis may lead to further major downstream complications such as stroke, hemorrhage, and hemodynamic alterations causing syncope. Therefore, surgical excision of a cystic cardiac mass is justified to establish a definitive histopathological diagnosis and prevent further downstream complications. We hereby report a rare case of cystic cardiac myxoma in the left atrium showing intense progressive enhancement in CMR and CTA in a middle-aged woman presenting with acute stroke. This case highlights an exceedingly rare variant of cystic cardiac myxoma.

Left Atrial Myxoma Hypervascularized from the Right Coronary Artery: An Interesting Cath Lab Finding.

Project description:Primary cardiac tumors are rare and approximately half of them are atrial myxomas. They rarely remain asymptomatic, especially if large. The imaging of a myxoma by contrast dye during coronary angiography is an infrequent sign, which clarifies the vascular supply of the tumor. We report herein an interesting and rare case of a left atrial myxoma hypervascularized from the right coronary artery.

Left Ventricular Hypertrabeculation (LVHT) in Athletes: A Negligible Finding?

Project description:Left ventricular hypertrabeculation (LVHT) used to be a rare phenotypic trait. With advances in diagnostic imaging techniques, LVHT is being recognised in an increasing number of people. The scientific data show the possibility of the overdiagnosis of this cardiomyopathy in a population of people who have very high levels of physical activity. We describe the case of a young athlete with no medical history, who presented with syncope during a marathon running race. Initial evaluation showed elevated troponin I; transthoracic echocardiography showed a trabeculated ventricle and subsequent cardiac magnetic resonance (CMR) revealed left ventricular hypertrabeculation (LVHT). During subsequent evaluation by tilt table testing, vasovagal syncope was identified as the likely aetiology of the syncope. The patient was advised to cease sports and stimulants like caffeine use. At the 29-month follow-up, CMR showed the normalisation of the non-compacted to compacted myocardial ratio and an improvement in left ventricular function, with no further syncopal episodes reported. This is an example of the physiological hypertrabeculation of the LV apex in a recreational endurance athlete, with the normalisation of the non-compacted to compacted myocardial layer ratio after detraining. Physiological hypertrabeculation, a benign component of exercise-induced cardiac remodelling, must be differentiated from non-compaction cardiomyopathy and other pathologies causing syncope. This case underscores the importance of distinguishing physiological hypertrabeculation from pathological LVHT in athletes, highlighting that exercise-induced cardiac remodelling can normalise with detraining.
