Total Transcatheter Stage 1: A Word of Caution.

Pediatr Cardiol 2021 Apr 29. Epub 2021 Apr 29.

Division of Cardiology, Department of Pediatrics, Washington University in St. Louis School of Medicine, One Children's Place, Northwest Tower, Box 8116, St. Louis, MO, 63110, USA.

For patients with single ventricle physiology, being able to initially establish systemic blood flow and control pulmonary blood flow is critical to their long-term health. Recently, there have been descriptions in achieving this by a purely transcatheter approach with stenting of the ductus arteriosus and implanting pulmonary flow restrictors, a very appealing prospect. We review a case series of 6 patients who underwent a percutaneous modified stage 1 approach using modified Microvascular plugs (MVP) at our center between September 2019 and December 2019.

Open-heart techniques and mitral valve plasty for mitral regurgitation in toy- and small-breed dogs: A review.

Open Vet J 2021 Jan-Mar;11(1):14-26. Epub 2021 Jan 11.

Cardiac Surgery Team, Chayagasaka Animal Hospital, Nagoya, Japan.

In human medicine, in the past, open-heart techniques for low-bodyweight children and newborn babies with congenital heart disease were more difficult than high-bodyweight adults. In toy- and small-breed dogs with mitral regurgitation (MR), an acquired heart disease, these techniques are more difficult to perform than for congenital heart diseases in young medium-sized or large dogs because of old age and low body weight. Therefore, improved open-heart techniques and mitral valve surgery for severe MR in older toy- and small-breed dogs are essential. Read More
