Resumen
La disrupción anular mitral (DAM), una anomalía cardíaca, puede causar arritmias ventriculares. La resonancia magnética cardíaca es crucial para diagnosticar la DAM y guiar el tratamiento para prevenir la muerte súbita cardíaca.
Área de la Ciencia:
- Cardiología
- Imagen Cardíaca
- Electrofiología
Sus antecedentes:
- La disrupción anular mitral (DAM) es una anomalía estructural cardíaca poco reconocida.
- La DAM se asocia cada vez más con arritmias ventriculares y muerte súbita cardíaca.
Objetivo del estudio:
- Informar un caso de taquicardia ventricular secundaria a disrupción anular mitral.
- Destacar el papel de la imagen por resonancia magnética cardíaca (RMC) en el diagnóstico de la DAM y los sustratos arritmogénicos asociados.
Principales métodos:
- Reporte de caso de un paciente que se presenta con palpitaciones y taquicardia ventricular no sostenida.
- El estudio diagnóstico incluyó ECG de 12 derivaciones, angiografía coronaria e imagen por resonancia magnética cardíaca (RMC).
Principales resultados:
- Las arterias coronarias se mostraron normales en la angiografía coronaria.
- La RMC confirmó la disrupción anular mitral (DAM) e identificó fibrosis focal del músculo papilar, un sustrato arritmogénico.
- La función sistólica del ventrículo izquierdo se conservó, sin evidencia de isquemia o miocarditis.
Conclusiones:
- Se debe considerar la DAM en pacientes con arritmias ventriculares y arterias coronarias normales.
- La imagen multimodal, especialmente la RMC, es vital para identificar la DAM, evaluar el riesgo y guiar el manejo.
- El reconocimiento y manejo tempranos de la DAM pueden reducir el riesgo de eventos cardíacos adversos.

01:20Mitral Regurgitation I: Introduction
423
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...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
223
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

01:22Mitral Stenosis I: Introduction
483
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...

438
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

01:27Mitral Valve Prolapse I: Introduction
393
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

01:25Mitral Regurgitation III: Medical Management
284
Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
