Post-ischaemic exuberant left ventricular mass: thrombus vs. tumour-case report.
Ontology highlight
ABSTRACT: Background
We present a case that illustrates the diagnostic challenge of differentiating thrombus from tumour when confronted with a large left ventricular (LV) cardiac mass.Case summary
A 43-year-old Caucasian woman polysubstance-abuser presented to a regional hospital with an ST-elevation myocardial infarction and underwent aspiration-thrombectomy and successful circumflex artery bare metal stenting. She was noted to have an exuberant LV mass on transthoracic echocardiogram the following day and transferred to our care. Transthoracic echocardiogram, transoesophageal echocardiogram, and cardiac magnetic resonance imaging were performed in an attempt to characterize the mass with conflicting findings for either thrombus or tumour. The mass was surgically excised and final pathology indicated a fibrin-rich thrombus.Discussion
The association of the mass with an infarcted area of the left ventricle supported the diagnosis of thrombus. However, due to the size and some imaging features a myxoma could not be completely ruled out. Atypical presentations of thrombus can be difficult to differentiate from cardiac tumours.

Project description:Left ventricular (LV) mass is a rare condition, of which the most common is thrombus. Echocardiography is a very useful modality of investigation to evaluate the LV mass. We are reporting a case of LV mass presenting with neurological symptom. The diagnosis of this mass was dilemma as the echocardiographic features were favoring tumor as well as thrombi. Mass (a) measuring 3.8 cm × 1.9 cm attached to the left ventricle apex appeared to be pedunculated tumor and mass (b) measuring 2.4 cm × 1.8 cm attached to the chordae of anterior mitral leaflet resembled a thrombus or an embolized tumor entangled in the chordae. A differential diagnosis for the LV mass is thrombus, tumors such as fibroma, and vegetation. Preoperative detection of a thrombus leads to an alteration in surgical steps. A large and mobile thrombus with or without a hemodynamic alteration is an indication for surgical removal to prevent stroke, myocardial infarction, mesenteric ischemia, renal infarction, gangrene of the limbs, and mortality.

Project description:BackgroundLeft ventricular aneurysms (LVAs) are a well-appreciated complication of acute myocardial infarction. Ventricular aneurysms involving the left ventricle (LV) typically evolve as a result of anterior myocardial infarction and are associated with greater morbidity, complication rates, and hospital resource utilization. Incidence of LVA is decreasing with advent of modern reperfusion therapies; however, in the setting of excess morbidity, clinicians must maintain an appreciation for their appearance to allow timely diagnosis and individualized care.Case summaryThis case report describes the clinical history, investigation, appearance, and management of a patient with calcified apical LVA with history of previous anterior ST-elevation myocardial infarction. The patient was initially admitted for elective coronary angiography in the setting of worsening exertional dyspnoea and subsequently underwent coronary artery bypass graft, aneurysm resection, and LV reconstruction.DiscussionLeft ventricular aneurysms are an uncommon complication experienced in the modern era of acute myocardial infarction and current reperfusion therapies, but remain an important cause of excess morbidity and complication. Evidence-based guidelines for the diagnosis, workup, and subsequent management of LVAs are lacking. The imaging findings presented in this case serve as an important reminder of the appearance of LVAs so that timely diagnosis and individualized care considerations can be made.

Project description:Left ventricular apical thrombus is a known complication following an anterior ST-elevation myocardial infarction. Although left ventriculography may suggest an apical thrombus in the presence of a filling defect, additional imaging with echocardiography and/or cardiac magnetic resonance is strongly recommended to further characterize the thrombus post myocardial infarction.

Project description:Male patient in dilated phase of hypertrophic cardiomyopathy had multiple hospitalizations during the past 2 years either due to congestive heart failure, stroke, scar epilepsy, or atrial fibrillation and ventricular tachycardia. Medication included evidence based therapy for heart failure, cordarone and warfarin. Anticoagulation had to be discontinued due to marked fluctuations in INR. Transthoracic Echocardiography (TTE) revealed a mobile mass in the left ventricle. He was treated with Dabigatran 110mg twice a day for 4 months without any bleeding or embolic episode and complete resolution of thrombus. Dabigatran is a reversible direct thrombin inhibitor and currently approved for the prevention of thromboembolic episodes in non-valvar atrial fibrillation. This case demonstrates possible thrombolytic properties of dabigatran in resolution of left ventricular thrombus.

Project description:BackgroundIntracardiac thrombi are a complication associated with cardiomyopathies. In heart failure with reduced ejection fraction, there is a hypercoagulable state that can increase the incidence of left ventricular thrombus and result in higher risk of thromboembolism, either manifested as stroke or as peripheral thromboembolic event. Haemoconcentration following decongestion treatment may enhance blood viscosity.Case summaryA 63-year-old man with known long-standing heart failure (HF) of ischaemic aetiology and not any prothrombotic risk, admitted with congestive HF and treated with aggressive decongestion treatment with intravenous loop diuretics. During his hospital stay, and following decongestion and haemoconcentration, a left ventricular (LV) intracardiac thrombus formation was detected by echocardiography, which occurred in the absence of a recent myocardial infarction or adverse LV remodelling. The patient was treated with oral anticoagulation therapy. There was a complete resolution of the thrombus on repeat transthoracic echocardiography after 4 weeks of treatment.DiscussionAggressive decongestive treatment, haemoconcentration and increased blood viscosity following HF decompensation may serve as a trigger for intracardiac thrombus formation under the appropriate prothrombotic background. Appropriate primary antithrombotic prophylaxis is an issue raised concerns and vulnerable patients need closed clinical and imaging follow-up.

Project description:Left ventricular thrombus (LVT) is a serious complication of acute myocardial infarction (MI) and also non-ischemic cardiomyopathies. We performed a narrative literature review, manual-search of reference lists of included articles and relevant reviews. Our literature review indicates that the incidence of LVT following acute MI has decreased, probably due to improvement in patient care as a result of better and earlier reperfusion techniques. Predictors of LVT include anterior MI, involvement of left ventricular (LV) apex (regardless of the coronary territory affected), LV akinesis or dyskinesis, reduced LV ejection fraction (LVEF), severe diastolic dysfunction and large infarct size. LVT is associated with increased risk of systemic embolism, stroke, cardiovascular events and death, and there is evidence that anticoagulant therapy for at least 3 months can reduce the risk of these events. Cardiac magnetic resonance (CMR) has the highest diagnostic accuracy for LVT, followed by echocardiography with the use of echocardiographic contrast agents (ECAs). Although current guidelines suggest use of vitamin K antagonist (VKA) for a minimum of 3 to 6 months, there is growing evidence of the benefits of direct acting oral anticoagulants in treatment of LVT. Embolic events appear to occur even after resolution of LVT suggesting that anticoagulant therapy needs to be considered for a longer period in some cases. Recommendations for the use of triple therapy in the presence of the LVT are mostly based on extrapolation from outcome data in patients with atrial fibrillation (AF) and MI. We conclude that the presence of LVT is more likely in patients with anterior ST-segment elevation MI (STEMI) (involving the apex) and reduced ejection fraction (EF). LVT should be considered a marker of increased long-term thrombotic risk that may persist even after thrombus resolution. Ongoing clinical trials are expected to elucidate the best management strategies for patients with LVT.

Project description:BackgroundPost-infarction perforation of the ventricular septum is recognized as a major complication of post-myocardial infarction. However, post-infarction ventricle dissection is seldom reported, as the ventricular shunt often accompanying this condition is a significant cause of cardiogenic shock. We encountered a rare case of ventricular dissection unaccompanied by a shunt, which caused a state of shock.Case presentationA 67-year-old man was diagnosed with acute myocardial infarction with a left ventricular oozing rupture. The occlusion of the left anterior descending artery was aspirated, followed by drainage of the pericardial bleeding and hemostasis of the left ventricle. After 15 h, he presented with sudden cardiogenic shock requiring extra-corporeal membrane oxygenation. The transesophageal echocardiogram showed a left ventricular septal aneurysm. Five days later, he underwent an operation, in which a ventricular septal wall dissection with a tear-forming large pseudoaneurysm was found. The tear was closed with a patch. He was weaned off extra-corporeal membrane oxygenation the next day. Αfter 4 months, he was discharged in a stable condition.ConclusionsRecognizing and identifying the cause of cardiogenic shock after myocardial infarction is crucial to provide the best treatment and surgical approach. Ventricular septal dissection should be considered, in addition to the usual complications, such as possible papillary muscle rupture, cardiac rupture, and perforation of the interventricular septum.

Project description:RationaleLeft ventricular non-compaction cardiomyopathy (LVNC) is a rare heart disorder related to thrombosis. Anticoagulant therapy is suggested for the treatment of this disease. The success of the novel oral anticoagulant rivaroxaban as a treatment option for this disorder is unclear.Patient concernsA 43-year-old man who felt dizzy at rest was found to have an intraventricular thrombus.DiagnosesThe thrombus was confirmed by echocardiography. And LVNC was diagnosed by cardiac magnetic resonance (CMR) and echocardiography.InterventionsHe was prescribed a low dose (10 mg daily) of rivaroxaban as treatment.OutcomesAfter 3 months, the thrombus diminished, and the manifestation disappeared.LessonsLow dose of rivaroxaban may serve as a viable option for anticoagulation therapy in LVNC patients, with large clinical trials needed to determine the best course of treatment.

Project description:Background and objectiveLeft ventricular thrombus (LVT) formation in patients with acute myocardial infarction (AMI) or cardiomyopathies is not uncommon. The optimal oral anticoagulation therapy for resolving LVT has been under intense debate. Vitamin K antagonists (VKAs) remain the anticoagulant of choice for this condition, according to practice guidelines. Evidence supporting the use of direct oral anticoagulants (DOACs) in the management of LVT continues to grow. We performed a systematic review and meta-analysis to compare the efficacy and safety of DOACs versus VKAs.MethodsA comprehensive literature search was carried out in PubMed, Cochrane Library, Web of Science, Embase, and Scopus databases in July 2023. The efficacy outcomes of this study were thrombus resolution, ischemic stroke, systemic embolism, stroke/systemic embolism, all-cause mortality, and adverse cardiovascular events. The safety outcomes were any bleeding, major bleeding, and intracranial hemorrhage. A total of twenty-seven eligible studies were included in the meta-analysis. Data were analyzed utilizing Stata software version 15.1.ResultsThere was no significant difference between DOACs and VKAs with regard to LVT resolution (RR = 1.00, 95% CI 0.95-1.05, P = 0.99). In the overall analysis, DOACs significantly reduced the risk of stroke (RR = 0.74, 95% CI 0.57-0.96, P = 0.021), all-cause mortality (RR = 0.70, 95% CI 0.57-0.86, P = 0.001), any bleeding (RR = 0.75, 95% CI 0.61-0.92, P = 0.006) and major bleeding (RR = 0.67, 95% CI 0.52-0.85, P = 0.001) when compared to VKAs. Meanwhile, in the sub-analysis examining randomized controlled trials (RCTs), the aforementioned outcomes no longer differed significantly between the DOACs and VKAs groups. The incidences of systemic embolism (RR = 0.81, 95% CI 0.54-1.22, P = 0.32), stroke/systemic embolism (RR = 0.85, 95% CI 0.72-1.00, P = 0.056), intracranial hemorrhage (RR = 0.59, 95% CI 0.23-1.54, P = 0.28), and adverse cardiovascular events (RR = 0.99, 95% CI 0.63-1.56, P = 0.92) were comparable between the DOACs and VKAs groups. A subgroup analysis showed that patients treated with rivaroxaban had a significantly lower risk of stroke (RR = 0.24, 95% CI 0.08-0.72, P = 0.011) than those in the VKAs group.ConclusionWith non-inferior efficacy and superior safety, DOACs are promising therapeutic alternatives to VKAs in the treatment of LVT. Further robust investigations are warranted to confirm our findings.
