The use of bioprosthetic valves (BPV) implanted surgically or by transcatheter valve implantation (TAVI) has increased dramatically in recent years as discussed by the authors.Abstract:
The use of bioprosthetic valves (BPV) implanted surgically or by transcatheter valve implantation (TAVI) has increased dramatically in recent years. Currently, BPVs comprise an overwhelming majorit...read more

Aortic dissection in the first trimester; is it a dead end? A narrative review of recent articles
Aryan Ayati,Syna Sarraf,Sahar Asl Fallah,Jamshid Bagheri,Hossein Ahmadi Tafti,Kaveh Same,Kaveh Hosseini +6 more
TL;DR: Aortic dissection during pregnancy is considered a rare and potentially fatal complication for both mother and fetus as mentioned in this paper , and the definite treatment for an acute-type AD is considered to be open-heart surgery, but the decision to perform such a surgery during pregnancy requires a multidisciplinary approach and carries significant risks.

Prevalence and Predictive Factors of Early Degeneration of Bioprosthetic Mitral Valves: A Single-Center Cohort Study
Akbar Shafiee,Aryan Ayati,Elnaz Salimi,Mohammad Sahebjam,Abbas Salehi Omran,Alireza Hadizadeh,Arezou Zoroufian +6 more
TL;DR: In this article , the frequency and predictors of early degeneration of mitral valve were investigated using the Cox regression hazards model, and the only independent predictor was a high MV mean gradient in the first postoperative echocardiography.
Book ChapterDOI
Cardiac valve replacement and related interventions
TL;DR: In this paper , the authors provide a broad overview and approach to the analysis of different prosthetic heart valves that may be encountered as surgical pathology or autopsy specimens (and potentially in a research setting).

Transcatheter Aortic-Valve Implantation for Aortic Stenosis in Patients Who Cannot Undergo Surgery
Martin B. Leon,Craig R. Smith,Michael J. Mack,D. Craig Miller,Jeffrey W. Moses,Lars G. Svensson,E. Murat Tuzcu,John G. Webb,Gregory P. Fontana,Raj Makkar,David L. Brown,Peter C. Block,Robert A. Guyton,Augusto D. Pichard,Joseph E. Bavaria,Howard C. Herrmann,Pamela S. Douglas,John L. Petersen,Jodi J. Akin,William N. Anderson,Duolao Wang,Stuart J. Pocock +21 more
TL;DR: In patients with severe aortic stenosis who were not suitable candidates for surgery, TAVI, as compared with standard therapy, significantly reduced the rates of death from any cause, the composite end point of deathFrom any cause or repeat hospitalization, and cardiac symptoms, despite the higher incidence of major strokes and major vascular events.

Transcatheter versus Surgical Aortic-Valve Replacement in High-Risk Patients

TL;DR: In high-risk patients with severe aortic stenosis, transcatheter and surgical procedures for aorti-valve replacement were associated with similar rates of survival at 1 year, although there were important differences in periprocedural risks.

TL;DR: A 2-year follow-up of patients in the PARTNER trial supports TAVR as an alternative to surgery in high-risk patients, but paravalvular regurgitation was more frequent after T AVR and was associated with increased late mortality.

Pocock,Craig R. Smith,Martin B. Leon +24 more
TL;DR: Among appropriately selected patients with severe aortic stenosis who were not suitable candidates for surgery, TAVR reduced the rates of death and hospitalization, with a decrease in symptoms and an improvement in valve hemodynamics that were sustained at 2 years of follow-up.

Outcomes 15 years after valve replacement with a mechanical versus a bioprosthetic valve: final report of the Veterans Affairs randomized trial.

TL;DR: At 15 years, patients undergoing AVR had a better survival with a mechanical valve than with a bioprosthetic valve, largely because primary valve failure was virtually absent with mechanical valve.
