Article Synopsis
- Current guidelines suggest implanting defibrillators in patients with acute myocardial infarction (AMI) who have low left ventricular ejection fraction (LVEF) to prevent sudden cardiac death (SCD).
- A study evaluated 441 AMI patients with LVEF ≤40% to identify predictors of SCD, finding that QRS duration, severely reduced LVEF, and delayed reperfusion time were significant risk factors.
- The combination of these three factors (QRSd ≥100 msec, LVEF ≤23%, and reperfusion time >5.5 hours) provided strong risk stratification for SCD after AMI, highlighting the need for close monitoring of patients with these conditions.
Article Synopsis
- The study investigates the prognostic value of von Willebrand factor antigen (vWF:Ag) in adults with congenital heart disease (ACHD), specifically focusing on its relationship to right-sided heart failure (RHF) and liver congestion.
- Researchers measured vWF:Ag levels in 382 ACHD patients and found that high levels of vWF:Ag were significantly associated with increased risks of mortality and linked to factors like older age and lower arterial oxygen saturation.
- The findings suggest that elevated vWF:Ag could serve as a vital biomarker for assessing RHF severity and predicting all-cause mortality in ACHD patients, highlighting its potential for clinical monitoring.

Article Synopsis
- A 45-year-old man developed deep vein thrombosis (DVT) complications linked to his inferior vena cava (IVC) filter, which was totally covered in a large thrombus.
- The medical team decided to remove the IVC filter, suspecting it might have caused a metallic allergy, and successfully did so using a multi-step catheter intervention technique.
- This case is noted as the first documentation of using multi-step catheter intervention for the retrieval of an IVC filter covered in massive thrombus, highlighting the severity and difficulty of IVC filter thrombosis.
