Baseline MDCT findings after prosthetic heart valve implantation provide important complementary information to echocardiography for follow-up purposes [PDF]

, 2016
Objectives: Recent studies have proposed additional multidetector-row CT (MDCT) for prosthetic heart valve (PHV) dysfunction. References to discriminate physiological from pathological conditions early after implantation are lacking.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

The Heart Team during the Pandemic: A Case Report of Bio-Prosthesis Degeneration Treated with Valve in Valve Implantation

Journal of Cardiovascular Echography
The pandemic changed the type of patients. The concept of “patient at the center” became concrete. The execution of simple consultancy was overcome to create effective collaboration and fruitful exchanges between specialists. The “Heart Team” model is on increasing affirmation.

Early experience with percutaneous transcatheter implantation of heart valve prosthesis for the treatment of end-stage inoperable patients with calcific aortic stenosis

Journal of the American College of Cardiology, 2004
This study was done to assess the results of percutaneous heart valve (PHV) implantation in non-surgical patients with end-stage calcific aortic stenosis.Replacement of PHV has been shown to be feasible in animals and humans. We developed a PHV composed of three pericardial leaflets inserted within a balloon-expandable stainless steel stent.

Early Outcomes After Total Arch Replacement With Frozen Elephant Trunk in Elderly Patients With Acute Type A Aortic Dissection

AGING MEDICINE, EarlyView.
Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...
