Insights
This study details a successful transaortic video-assisted thrombectomy for left ventricular thrombus after acute myocardial infarction. The minimally invasive technique avoided ventriculotomy, preserving function in patients with compromised cardiac health.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- Interventional Cardiology
Background:
- Acute myocardial infarction can lead to left ventricular thrombus formation.
- Traditional surgical approaches for thrombus removal may require ventriculotomy, potentially worsening ventricular function.
- Minimally invasive cardiac surgery is gaining traction for various cardiac conditions.
Observation:
- A 59-year-old male patient presented with acute myocardial infarction due to left anterior descending (LAD) artery occlusion.
- Percutaneous transluminal coronary angioplasty (PTCA) with stenting successfully recanalized the LAD.
- A transaortic video-assisted thrombectomy was performed under endoscopic guidance to remove a left ventricular apical thrombus.
Findings:
- The transaortic video-assisted thrombectomy successfully and safely removed the left ventricular thrombus.
- The procedure was performed under cardiopulmonary support using endoscopic visualization.
- No left ventriculotomy was required, preserving the patient's ventricular function.
Implications:
- Transaortic video-assisted thrombectomy is a viable minimally invasive option for managing left ventricular thrombus post-myocardial infarction.
- This technique is particularly beneficial for patients with compromised ventricular function.
- Endoscopic guidance facilitates safe and effective thrombus removal in the left ventricular cavity.
Abstract:
In recent years much attention has been paid to a minimal invasive surgery even in the field of cardiac surgery. We have successfully treated a 59 year-old male who underwent transaortic video-assisted thrombectomy in the left ventricular cavity following acute myocardial infarction due to occlusion (No. 7) of the left descending coronary artery (LAD). After the LAD was recanalized by percutaneous transluminal coronary angioplasty (PTCA) and then stenting, this thrombectomy was carried out. Following initiation of cardiopulmonary support, thrombus in the left ventricular apex was safely removed by transaortic endoscopic guidance. This technique was useful especially for the patient with poor ventricular function due to acute myocardial infarction because of no left ventriculotomy. Endoscopic guidance technique is reported in detail.
