First 10 transcatheter pulmonary valve-in-valve procedures in rajaie cardiovascular medical and research center

Research in Cardiovascular Medicine, 2022
Background: Transcatheter pulmonary valves (TPVs) are feasible and much less invasive options for surgical right ventricular outflow tract (RVOT) repair or valve replacement in patients with degeneration of the pulmonary valve bioprosthesis or RVOT ...

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Pulmonary valvulotomy in a fetus with pulmonary atresia with intact ventricular septum : first experience in Turkey [PDF]

, 2012
The mortality and morbidity of children with pulmonary atresia with intact ventricular septum (PA/IVS) is closely related with right ventricle hypoplasia and its consequent hemodynamics.

Pulmonary valve stenosis due to undifferentiated pleomorphic sarcoma [PDF]

, 2015
Pulmonary artery sarcomas are uncommon intracardiac tumours with poor prognosis. We report the case of a 69-year-old woman in good health presenting with rapidly progressive dyspnoea and an unfamiliar systolic murmur.

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

Advanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these

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 ...

Initial experience with Edwards SAPIEN valve transcatheter implantation in native RVOT in Latvia

Acta Medica Lituanica, 2020
Transcatheter pulmonary valve implantation has been a well-known method for more than a decade, but there are still many challenging cases when a personalized solution is needed.

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 ...
