Summary
A left superior pulmonary vein thrombus was observed after mitral valve transcatheter edge-to-edge repair (TEER). This thrombus resolved after Watchman device placement, suggesting TEER-induced damage may cause pulmonary vein thrombosis.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcatheter edge-to-edge repair (TEER) is a minimally invasive procedure for mitral valve disease.
- Watchman device implantation is used for stroke risk reduction in patients with atrial fibrillation.
- Complicated medical histories can influence procedural outcomes and patient management.
Observation:
- A 76-year-old female underwent Watchman device placement two months post-mitral valve TEER.
- Preoperative imaging revealed a thrombus in the left superior pulmonary vein.
- Post-Watchman implantation echocardiography confirmed the absence of thrombus in the left atrial appendage and pulmonary veins.
Findings:
- A thrombus was identified in the left superior pulmonary vein prior to Watchman device implantation.
- The thrombus resolved following the Watchman procedure.
- The resolution of the thrombus suggests a potential link to the preceding TEER procedure.
Implications:
- The findings suggest that mitral valve TEER may be associated with the secondary development of pulmonary vein thrombus.
- Epithelium damage during TEER could be a potential mechanism for thrombus formation.
- Further investigation is warranted to understand the incidence and management of pulmonary vein thrombus after TEER.

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...

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...

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...

565
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...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.

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...
