Fluid Mechanics of Fetal Left Ventricle During Aortic Stenosis with Evolving Hypoplastic Left Heart Syndrome.

Ann Biomed Eng 2022 Jun 22. Epub 2022 Jun 22.

Department of Bioengineering, Imperial College London, London, UK.

In cases of fetal aortic stenosis and evolving Hypoplastic Left Heart Syndrome (feHLHS), aortic stenosis is associated with specific abnormalities such as retrograde or bidirectional systolic transverse arch flow. Many cases progressed to hypoplastic left heart syndrome (HLHS) malformation at birth, but fetal aortic valvuloplasty can prevent the progression in many cases. Since both disease and intervention involve drastic changes to the biomechanical environment, in-vivo biomechanics likely play a role in inducing and preventing disease progression. Read More

A novel "proximal first" Inoue balloon catheter for retrograde aortic valvuloplasty: Initial case report.

Catheter Cardiovasc Interv 2022 Jun 30;99(7):2131-2135. Epub 2022 Mar 30.

Department of Cardiology, Kawasaki Heart Center, Kawasaki Saiwai Hospital, Kawasaki, Kanagawa, Japan.

The Inoue balloon, invented for percutaneous transseptal mitral commissurotomy for mitral stenosis, is initially dilated in the distal portion and then the proximal portion, forming an hourglass shape that stabilizes the balloon at the mitral valve orifice with a pulling action. The device has been successfully applied to antegrade aortic valvuloplasty; the hourglass shape stabilizes the balloon across the aortic valve without rapid ventricular pacing. Subsequently, an Inoue balloon was developed for retrograde aortic valvuloplasty using the same design as the antegrade balloon. Read More

History of Surgery for Mitral Stenosis: John Mayow to Charles Bailey.

Ann Thorac Surg 2022 06 17;113(6):2097-2101. Epub 2022 Jan 17.

Department of Cardiothoracic Surgery, Stanford University, Stanford, California. Electronic address:

Mitral stenosis was first described in 1674 by Englishman John Mayow, but surgical intervention for mitral stenosis was proposed over 2 centuries later in 1898. Mitral valve surgery was undertaken in the 1920s with varying success; after 2 decades of staggered progress, mitral valvuloplasty and commissurotomy would be rediscovered by Americans Horace Smithy, Charles Bailey, and Dwight Harken. The evolution of open surgery for mitral stenosis suggests the troubled triumph of humanity over disease while also underlining surgeons' inability to successfully disseminate their pioneering ideas to a community critical of innovation.
