We present a 2-month-old girl with chondrodysplasia punctata in whom bilateral peripheral pulmonary artery stenoses were successfully treated by transcatheter balloon angioplasty. The minimal diameters of the right and left pulmonary arteries of 1.3 mm and 1.1 mm, respectively, which were dilated using a 4-mm balloon catheter. Balloon angioplasty is feasible and effective for relieving peripheral pulmonary artery stenosis in patients with chondrodysplasia punctata.

Rotational Atherectomy Followed by Modified (Cutting or Scoring) Balloon Versus Plain Balloon Before Drug‑Eluting Stent Implantation for Calcified Coronary Lesions: A Meta-Analysis.
Catheter Cardiovasc Interv

Coronary calcification is a major factor leading to stent under-expansion, and subsequent adverse events. This meta-analysis aimed to evaluate the short and long‑term outcomes of rotational atherectomy (RA), followed by modified balloon (cutting or scoring) (MB) versus plain balloon before drug‑eluting stent implantation for calcified coronary lesions. We searched PubMed, Web of Science (WOS), Scopus, and the Cochrane Library Central Register of Controlled Trials (CENTRAL), from inception until 30 January 2024.

Endovascular treatment of femoropopliteal artery (FPA) disease with Drug-coated balloons (DCBs) may face complications such as arterial recoil, dissection, and residual stenosis. Angiography has limited accuracy for evaluating blood flow through revascularized target lesions. Thus, there is a need for post-procedure hemodynamic assessment in treated limbs.

Objectives: To evaluate the role of shear wave elastography (SWE) in distinguishing acute from subacute thrombi in thrombosed arteriovenous fistulas (AVFs) and explore the relationship between thrombus stiffness and outcomes of balloon angioplasty.
Materials And Methods: This retrospective study included 44 dialysis patients with thrombosed AVFs from June 2022 to June 2024. Patients underwent Doppler ultrasound and SWE to assess thrombus age, followed by balloon angioplasty.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.

We report a case of right ventricle to pulmonary artery conduit angioplasty in which a valvuloplasty balloon ruptured circumferentially and was retained within the conduit. A high-pressure balloon was used to relieve the obstruction and free the ruptured balloon. The procedure was further complicated when the distal part of the balloon broke away from the proximal part during an attempt to retrieve it back into the femoral sheath.
