The performance of the St. Jude prosthetic valve is reviewed in 81 patients aged 3 to 15 years. All 66 mitral (2 re-replacements), 8 aortic and 9 double valve replacements between February 1979 and August 1984 are included. The early mortality was 3.7% and actuarial analysis shows a 90% event free survival up to 5 years. Anticoagulant therapy was used in most patients, but comparison between groups receiving warfarin or aspirin or no therapy reveals no differences in the complication rate. The valve is well suited for use in children since the early degeneration seen with heterograft valves does not occur, and anticoagulation is not essential.

Clarifying the Cardiovascular Morphology and Associated Abnormalities in Patients with Double Inlet Right Ventricle Using Multidetector CT Angiography.
Pediatr Cardiol

Department of Cardiovascular Radiology & Endovascular Interventions, All India Institute of Medical Sciences, New Delhi, 110029, India.
We sought to evaluate the intracardiac morphology and associated cardiovascular anomalies in patients with double inlet right ventricle (DIRV) on multidetector CT angiography. A retrospective search of our departmental database was conducted from January 2014 to January 2023 to identify patients with a diagnosis of DIRV on CT angiography. The intracardiac anatomy and associated cardiovascular abnormalities were systematically evaluated.

Background: Minimally invasive cardiac surgery for mitral regurgitation is challenging in patients with narrow chests due to limited thoracic space. The butterfly technique can prevent systolic anterior motion in patients with degenerative mitral regurgitation and redundant posterior leaflets, but it is difficult to perform via minimally invasive cardiac surgery. Few reports have described mitral valve repair using the butterfly technique or in a narrow chest.

Budd-Chiari syndrome with obstruction in the inferior vena cava causes increased venous pressure in the azygous-hemiazygous system and paravertebral venous plexus, which is transmitted to the epidural venous plexus, devoid of the valves. It causes epidural venous plexus engorgement and venous congestion and may present rarely with low back pain or radiating pain. However, patients developing lower limb weakness as a complication of Budd-Chiari syndrome is an infrequent and severe presentation.

Cardiovascular Center, Anjo Kosei Hospital, Anjo, Japan.
Background: The prognostic implications of cerebral microbleeds (CMBs) in patients who undergo transcatheter aortic valve replacement (TAVR) have not been fully elucidated. Therefore, we aimed to investigate the association between the presence of CMBs and adverse outcomes post-TAVR.
Methods: In this single-center retrospective study, we included 124 patients who underwent brain magnetic resonance imaging before TAVR.
Closed Treatment of the Internal Nasal Valve.
Otolaryngol Clin North Am
January 2025
Department of Otolaryngology-Head and Neck Surgery, Louisiana State University Health Sciences Center, New Orleans, LA, USA; Our Lady of the Lake Regional Medical Center, Baton Rouge, LA, USA. Electronic address:
The internal nasal valve, the narrowest portion of the nasal airway, is prone to collapse and is often targeted for improvement in nasal reconstruction and rhinoplasty. Endonasal techniques can reduce surrounding trauma and reduce operative times compared to traditional open methods. Options include the use of spreader, butterfly and alar batten grafts, suspension and flaring sutures, and Z-plasty for scarring.
