Trombos Rudimentario en Ventrículo Derecho que Conduce a Accidente Cerebrovascular Multifocal en la Circulación de
Irish medical journal
|February 23, 2026
Resumen
Los pacientes con circulación de Fontan enfrentan un alto riesgo de tromboembolismo. Un trombo en el ventrículo derecho rudimentario causó un accidente cerebrovascular multifocal, lo que enfatiza la necesidad de evaluar accidentes cerebrovasculares en estos pacientes con síntomas neurológicos.
Área de la Ciencia:
- Cardiología
- Neurología
- Medicina Vascular
Sus antecedentes:
- Los pacientes con circulación de Fontan tienen un mayor riesgo de eventos tromboembólicos.
- Las estructuras cardíacas residuales, como un ventrículo derecho rudimentario, pueden ser una fuente de formación de trombos.
Objetivo del estudio:
- Informar un caso de accidente cerebrovascular multifocal en un paciente de Fontan.
- Destacar la importancia de considerar el accidente cerebrovascular en pacientes de Fontan que presentan síntomas neurológicos.
Principales métodos:
- El diagnóstico implicó TC y RM/ARM cerebral, ecocardiografía transtorácica y ecocardiografía transesofágica.
- El tratamiento incluyó atención multidisciplinaria y terapia anticoagulante.
Principales resultados:
- Se identificó un trombo dentro del ventrículo derecho rudimentario como la causa de infartos embólicos multifocales.
- El paciente fue tratado con anticoagulación dirigida a un INR de 2-3.
Conclusiones:
- Las estructuras cardíacas rudimentarias en pacientes de Fontan plantean un riesgo persistente de eventos tromboembólicos.
- La imagen multimodal es crucial para diagnosticar accidentes cerebrovasculares secundarios a trombos en el VD.
- Las estrategias óptimas de tromboprofilaxis en esta población requieren una mayor investigación.

01:22Mitral Stenosis I: Introduction
888
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

01:30Venous Thrombosis I: Introduction
535
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...

01:20Mitral Regurgitation I: Introduction
678
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

01:21Coronary Circulation
7.8K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

01:15Aortic Regurgitation I: Introduction
828
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

01:29Pulmonary Embolism I: Introduction
942
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...
