The three-vessel view (3VV) is a standardized transverse scanning plane used in fetal cardiac ultrasound screening to measure the absolute and relative diameters of the pulmonary artery (PA), ascending aorta (Ao), and superior vena cava, as required. The PA/Ao ratio is used to support the diagnosis of congenital heart disease (CHD). However, vascular diameters are measured manually by examiners, which causes intra- and interobserver variability in clinical practice.

- Left ventricular (LV) pseudoaneurysm is a rare but serious complication that can occur after a heart attack or heart surgery, often manifesting years later, as seen in the case of an 83-year-old man who developed it 18 years post-Dor operation.
- The patient experienced rapid heart enlargement and dyspnea, which was diagnosed as an LV pseudoaneurysm through various non-invasive imaging techniques, revealing that the suture connecting the patch to the heart muscle weakened over time.
- Although surgery is typically recommended due to the high risk of rupture, the patient was not a suitable candidate due to age and renal issues, so he was treated conservatively with medication for hypertension and heart failure.
Staphylococcus aureus can cause outbreaks and becomes multi-drug resistant through gene mutations and acquiring resistance genes. However, why S. aureus easily adapts to hospital environments, promoting resistance and recurrent infections, remains unknown.
