Article Synopsis
  • Some people with a heart problem called myocardial infarction (MI) might actually have a small hole in their heart called a patent foramen ovale (PFO) that lets dangerous clots pass through.
  • Doctors used a special test called optical coherence tomography (OCT) to study patients who had MI but normal heart arteries to see if they had any clots stuck in the PFO.
  • They found that in two out of three patients, there were signs of sticky clots inside the PFO, and after treating them, none of the patients felt chest pain again.

Article Synopsis
  • Researchers found a rare case where a heart attack happened because of a small hole in the heart called a patent foramen ovale (PFO).
  • They used a special camera called optical coherence tomography to see the clots (or thrombi) in the PFO channel.
  • The study suggests that these clots could be a reason for heart attacks in people with a PFO, not just the usual way clots travel in the body.

Background: We describe a rare case of patent foramen ovale (PFO) associated stroke in a patient with pulmonary embolism, inferior vena cava thrombosis and undergoing filter implantation who successfully underwent PFO closure using the right internal jugular venous approach.

Case Summary: This is a rare case of a 42-year-old patient who presented with stroke and pulmonary embolism and was diagnosed with a PFO, inferior vena cava thrombosis and underwent filter implantation. The patient suffered from stroke and pulmonary embolism successively; that is, embolic events occurred in both the arterial and venous systems.

Background: Multiple atrial septal defects (ASD) with an inferior sinus venosus defect (SVD) have always been considered to be contraindications for interventional therapy. On the basis of early experience using a patent ductus arteriosus (PDA) occluder for interventional treatment for inferior ASD, this study investigated the feasibility of transcatheter closure of multiple ASDs with an inferior SVD under the guidance of three-dimensional (3D) printed heart models.

Methods: Between August 2016 and February 2017, five patients who were diagnosed with multiple ASDs with an inferior SVD at the First Affiliated Hospital of Xi'an Jiaotong University underwent cardiac computed tomography (CT) scans and three-dimensional (3D) echocardiography to generate heart disease models by a 3D printing technique.

Paradoxical peripheral embolism and submassive pulmonary embolism (PE), secondary to cancer-associated thrombosis, are yet to be reported in the literature. Here we describe a case presenting with an acute peripheral arterial embolism. Subsequent testing revealed a PE and an intrahepatic cholangiocarcinoma as the likely risk factors for thrombus, with arterial spread likely achieved through a patent foramen ovale.

Background: The off-label use of various devices has been reported for the transcatheter closure of perimembranous ventricular septal defects (PmVSD) because of serious complications, such as heart block and tricuspid regurgitation (TR), associated with conventional ventricular septal defect devices. However, whether certain defects such as PmVSD with abnormally attached tricuspid are fit for interventional treatment is still disputable.

Aim: To explore the feasibility and safety of transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae using an improved patent ductus arteriosus (PDA) occluder.

Article Synopsis
  • The study aimed to investigate the relationship between atrial septal aneurysm (ASA) and migraines in patients with patent foramen ovale (PFO) who underwent closure surgery.
  • It included 450 patients aged 18-45 who had migraines and right-to-left shunts, comparing those with ASA to those without ASA regarding ischemic lesions and migraine types.
  • Results indicated that patients with ASA experienced a higher frequency of ischemic lesions and migraines with aura, as well as larger PFO sizes, although there was no significant difference in headache impact scores before and after the procedure.

Objective: Explore the feasibility and safety of transcatheter closure of perimembranous ventricular septal defects using a wire-drifting technique (WT) in children.

Methods: We retrospectively analyzed 121 pediatric patients diagnosed with perimembranous ventricular septal defects who underwent interventional treatment at the First Affiliated Hospital of Xi'an Jiaotong University from Dec 2011 to Dec 2014. Based on the method used for arteriovenous loop establishment during the procedure, the patients were divided into a conventional technique (CT) group and a WT group.

Objectives: To describe the multidisciplinary assessment of patent foramen ovale (PFO) with substantial right-to-left shunting (RLS) and medium-term follow-up after PFO closure for stroke or transient ischemic attack (TIA).

Background: PFO closure is a therapeutic option to prevent recurrent ischemic event in patients with cryptogenic stroke and TIA. The apparent lack of benefit seen in previous studies was in part due to the inclusion of patients with alternate mechanisms of stroke/TIA.

Pulmonary arterial hypertension (PAH) is a common clinical cardiovascular disease, leading to the excessive proliferation of pulmonary artery smooth muscle cells (PASMCs) and endothelial cells, and is associated with a high mortality rate. Recently, stem- and progenitor cell-mediated gene therapies have provided a novel approach for the treatment of PAH. However, the function of human bone marrow-derived mesenchymal stem cells (hBM‑MSCs) modified with the insulin-like growth factor binding protein-3 (IGFBP-3) gene in the regulation of PAH is not yet fully understood.

  • Pancreaticoduodenectomy (PD) is the preferred treatment for pancreatic head or periampullary lesions, with two main types: pylorus-preserving (PPPD) and pylorus-resecting (PRPD).
  • A systematic review of 9 randomized controlled trials involving 722 participants compared postoperative complications, focusing on overall morbidity and specific issues like pancreatic fistulas and delayed gastric emptying (DGE).
  • The study found no significant differences in overall morbidity between PPPD and PRPD, but PRPD had a lower DGE rate, particularly in the subtotal stomach-preserving group, indicating further research is needed to determine the optimal surgical approach.
