Cor Triatriatum and Recurrent Thromboembolic Stroke

Summary
Cor triatriatum, a rare heart defect, can cause recurrent strokes. Anticoagulation therapy may be less effective than expected for preventing embolic stroke in patients with this condition.
Area of Science:
- Cardiology
- Neurology
- Medical Imaging
Background:
- Cor triatriatum is a rare congenital heart anomaly.
- It can present with symptoms mimicking ischemic stroke.
- Recurrent thromboembolic events are a potential complication.
Purpose of the Study:
- To report a case of recurrent thromboembolic stroke in a patient with undiagnosed cor triatriatum.
- To discuss the diagnostic challenges and treatment implications of this rare condition.
Main Methods:
- Case report detailing a middle-aged female patient's clinical course over 6 years.
- Review of diagnostic modalities including transthoracic echocardiography and CT angiography.
- Analysis of treatment strategies, including anticoagulation and surgical considerations.
Main Results:
- The patient experienced multiple strokes despite various anticoagulation regimens.
- Cor triatriatum was confirmed as the underlying cause.
- Diagnosis was challenging and required advanced imaging.
Conclusions:
- Cor triatriatum necessitates specific diagnostic approaches beyond routine echocardiography.
- Surgical membrane resection is the primary treatment.
- Anticoagulation may have limited efficacy in preventing embolic strokes in cor triatriatum.

23
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

01:29Pulmonary Embolism I: Introduction
19
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

01:29Venous Thrombosis III: Interprofessional Care
16
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
24
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

01:24Disorders of Hemostasis
1.0K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
