Article Synopsis
- Radiofrequency catheter ablation is recognized as the primary treatment option for idiopathic premature ventricular complexes (PVCs) and ventricular tachycardias (VTs), but its effectiveness varies by type of PVC/VT.
- A retrospective study conducted in a high-volume center in Guizhou, China, analyzed 1028 patients who underwent their first catheter ablation between 2013 and 2022, assessing factors like success rates and complications.
- The study revealed a 90.3% acute success rate, with complications more prevalent in left ventricular PVC/VT patients, while follow-up showed certain types of PVC/VTs had lower recurrence risk, indicating catheter ablation is effective for various locations except for those presenting with left
Article Synopsis
- Cardiac CT (CCT) is being evaluated for its effectiveness in detecting left atrial appendage (LAA) thrombus in patients with atrial fibrillation, using trans-oesophageal echocardiography (TEE) as the benchmark.
- The study involved 726 patients from a Chinese hospital and found that CCT was able to detect 89.3% of LAA thrombi but only 48.3% of thrombi located at the LAA ostium, revealing discrepancies in detection rates.
- The analysis concluded that CCT is generally less sensitive than TEE for identifying LAA thrombi, particularly for smaller ones with fast blood flow, suggesting that TEE remains the more reliable method for this specific
