Emergent Cardiac Surgery After Transcatheter Structural Heart Procedures: Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter structural heart procedures have become standard therapy for elderly patients with high surgical risk. Over time, these procedures have significantly increased worldwide, accompanied by a concomitant reduction of major complications, including those requiring emergent cardiac surgery (ECS).

Transcatheter tricuspid valve‐in‐valve implantation for degenerative surgical bio‐prosthesis using SAPIEN 3: A case series

Clinical Case Reports, 2021
We evaluated early outcomes of transcatheter valve‐in‐valve (ViV) implantation in patients with degenerated bio‐prosthesis in tricuspid position. Total of 5 patients were included in our case series.

Experimental investigation of the flow downstream of a dysfunctional bileaflet mechanical aortic valve [PDF]

arXiv, 2019
Mechanical heart valve replacement is the preferred alternative in younger patients with severe symptomatic aortic valve disease. However, thrombus and pannus formations are common complications associated with bileaflet mechanical heart valves. This leads to risks of valve leaflet dysfunction, a life threatening event.

Modeling the Mitral Valve [PDF]

, 2019
This work is concerned with modeling and simulation of the mitral valve, one of the four valves in the human heart. The valve is composed of leaflets, the free edges of which are supported by a system of chordae, which themselves are anchored to the papillary muscles inside the left ventricle.

Impact of Prosthesis‐Patient Mismatch After Surgical Aortic Valve Replacement: Systematic Review and Meta‐Analysis of Reconstructed Time‐to‐Event Data of 122 989 Patients With 592 952 Patient‐Years

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease
Background It remains controversial whether prosthesis‐patient mismatch (PPM) impacts long‐term outcomes after surgical aortic valve replacement.

Impact of Elevated Preprocedural Left Ventricular Filling Pressure on Prognosis of Mild Paravalvular Regurgitation Following Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.

Restoration of a Stuck Leaflet

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.

3D Printing-Assisted Energy Loss Testing of Artificial Aortic Heart Valves [PDF]

arXiv, 2019
With the development of additive manufacturing, 3D printing technology has become more common nowadays. We designed and 3D printed a cost-effective liquid fluid pressure measurement device that can convert liquid pressure to air pressure. Air pressure was measured by a low-cost manometer in this study.

Continuation Versus Interruption of Oral Anticoagulation During TAVI: A Systematic Review and Meta‐Analysis Oral Anticoagulation Management in TAVI

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Patients undergoing transcatheter aortic valve implantation (TAVI) often require long‐term oral anticoagulation (OAC), but it is unclear whether to continue or interrupt OAC during the procedure. This meta‐analysis compares clinical outcomes of continuing versus interrupting OAC during TAVI.

Selection of Prosthesis in Aortic Valve Surgery: Short Review and Trend in our Practice in 10 Years

Albanian Journal of Trauma and Emergency Surgery
Introduction: In our country, the predominant condition treated in aortic valve surgery in its early stages was aortic valve disease of rheumatic origin, primarily in patients under the age of 60.
