Mechanical prosthetic heart valves: Quality of anticoagulation and thromboembolic risk. The observational multicenter PLECTRUM study

, 2018
Background: Patients with a mechanical prosthetic heart valve implantation need to be treated with a vitamin K antagonist (VKA) due to a substantially high risk of thromboembolism. In this study we report data on patients with mechanical heart valves (MV)

Results of heart valve replacement with the SORIN prosthesis.

Texas Heart Institute journal, 1987
From March 1977 to December 1981, 872 patients at our institution underwent valve replacement with a pyrolytic carbon tilting disc prosthesis manufactured in Italy by SORIN-Biomedica. To verify the performance characteristics of this prosthesis, we analyzed the intermediate-term results obtained over a cumulative total of 3,041 patient-years (pt-yr) of

Pacing the Impossible: ICE‐ and Voltage‐Guided Atrial Leadless Pacemaker Implantation in Double Mechanical Valve Disease

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
A and B: Right atrial voltage mapping identified a limited region of viable myocardium within an extensive atrial scar. C: Intracardiac echocardiography guided safe deployment of an atrial leadless pacemaker. D and E: Fluoroscopy confirmed stable device positioning in the right atrial appendage of the patient.

Long-term outcomes of the Carpentier-Edwards pericardial valve prosthesis in the aortic position: effect of patient age.

, 2004
Pericardial bioprosthetic heart valves were introduced into clinical practice more than 30 years ago. Unfortunately, the long-term results were initially disappointing, particularly with regard to the limited durability of the prosthesis.

Bioprosthesis versus Mechanical Valve Heart Prosthesis: Assessment of Quality of Life

, 2019
Background: The aim of this study was to evaluate the QoL of patients undergoing heart valve replacement using the SF-36 questionnaire, compare it between patients with mechanical prosthesis and patients with bioprosthesis, and correlate the results with

Prognostic Factors for Postoperative Complications. An Aggregate Protocol for 10 Observational Studies From the Danish TRIPLE‐A Cohort of 1.2 Million Surgeries

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background Postoperative complications substantially increase morbidity, mortality and healthcare costs. Understanding prognostic factors is essential for risk stratification, targeted prevention strategies, and development of prediction models.

Anticoagulation in pregnancy with mechanical heart valves: 10-year experience

, 2007
Anticoagulation in pregnancy was evaluated in 33 women with a mechanical heart valve prosthesis who had 53 pregnancies between 1994 and 2006. Their mean age at valve operation was 24.4 ± 5.4 years, and 22 (67%) had isolated mitral valve disease. Of these

Radiation dose optimization in coronary CT angiography clinical application of absolute phase gating in patients with atrial fibrillation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Atrial fibrillation (AF) poses significant challenges for coronary CT angiography (CCTA) due to R‐R interval variability, often necessitating high radiation dose protocols. Absolute phase gating, which uses fixed millisecond delays rather than percentage‐based cardiac cycle timing, may optimize image quality while reducing radiation

Simultaneous Transvenous Lead Extraction and Intra‐Operative Epicardial Extravascular Defibrillator (EV‐ICD) Implantation During Tricuspid Valve Replacement

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Transvalvular device leads are undesirable following tricuspid valve replacement. Simultaneous lead extraction and intra‐operative EV‐ICD implantation can provide ongoing defibrillator therapy without crossing the prosthetic valve and may avoid the need for additional pacing hardware when atrioventricular conduction is preserved.

Critical uterine bleeding after miscarriage in a warfarin-anticoagulated patient with mechanical heart valve: a case report

Journal of Medical Case Reports
Background Patients with mechanical heart valves require lifelong oral anticoagulation with vitamin K antagonists such as warfarin to prevent valve-associated thromboembolism.
