Propensity Score Matched Analysis of Mechanical vs. Bioprosthetic Valve Replacement in Patients With Previous Stroke.
CONCLUSIONS: In patients with previous stroke, bioprosthetic valves had a lower incidence of complications connected to major bleeding than did the mechanical valves. Survival and stroke recurrence rates, however, did not differ between the 2 groups. We recommend bioprosthetic valves for patients >60 years or who have a history of GI bleeding.

Discrepancy of Aortic Valve Area Measurements by Doppler vs. Biplane Stroke Volume Measurements and Utility of Combining the Different Areas in Aortic Valve Stenosis 　- The Asian Valve Registry.
CONCLUSIONS: Discrepancy in AVAI by Doppler vs. biplane method was significantly more pronounced with increased LV outflow tract flow velocity, shorter height, lower weight, older age and smaller LV cavity dimensions. Combining the AVAIs enabled mutual and incremental value in predicting events. PMID: 33208592 [PubMed - as supplied by publisher]

Midterm Outcomes of Transcatheter Aortic Valve Replacement in Dialysis Patients With Aortic Valve Stenosis.
CONCLUSIONS: Satisfactory in-hospital outcomes were achieved in dialysis patients after TAVR. Various problems, however, such as complications particular to dialysis patients and valve durability, remained at midterm follow-up. Further studies are recommended to solve these problems, and prudent preoperative assessments should be mandatory. PMID: 31118365 [PubMed - as supplied by publisher]

Differences in Flow-Gradient Patterns Between Severe Bicuspid Aortic Stenosis and Severe Tricuspid Aortic Stenosis 　- Mechanistic Insight From Multimodal Imaging.
CONCLUSIONS: Flow-gradient patterns in bicuspid AS differ from those of tricuspid AS and are associated with the structural and functional characteristics of the aorta. PMID: 31787664 [PubMed - as supplied by publisher]

First Clinical Trial of a Self-Expandable Transcatheter Heart Valve in Japan in Patients With Symptomatic Severe Aortic Stenosis.
Conclusions: This is the first study to evaluate a self-expandable TAV in a Japanese patient population. The data show successful achievement of the study's primary objective and demonstrate the functional and anatomical effectiveness of the MDT-2111 TAV system.

Latest Advances in Transseptal Structural Heart Interventions.
Abstract Recent advances in structural heart intervention have produced increasing demand for transseptal access, which was first introduced as a diagnostic tool to directly measure left atrial pressure. Transseptal access allows safe and adequate approach to the left atrium and surrounding structures. Percutaneous transcatheter mitral valve repair using the MitraClip device is a safe and less invasive treatment for selected patients with significant mitral regurgitation, who are at high risk for surgery. This is an echocardiographic- and fluoroscopic-guided procedure requiring accurate transseptal access of the l...

Preoperative Tissue Doppler Imaging-Derived Atrial Conduction Time Can Predict Postoperative Atrial Fibrillation in Patients Undergoing Aortic Valve Replacement for Aortic Valve Stenosis.
Conclusions:The PA-TDI duration was an independent predictor of POAF after AVR for AS. Patients with PA-TDI duration >147 ms should be considered high risk and treated appropriately to improve outcomes. PMID: 25030299 [PubMed - as supplied by publisher]

Prognostic Value of Global Longitudinal Strain in Paradoxical Low-Flow, Low-Gradient Severe Aortic Stenosis With Preserved Ejection Fraction.
Conclusions:Longitudinal function was severely impaired in patients with LFLPG AS and they had poor prognosis. GLS could stratify the high-risk group for future adverse outcomes. Patients with paradoxical LFLPG AS comprised a mixed group with different LV mechanical properties associated with different prognoses. PMID: 25273913 [PubMed - as supplied by publisher]

Preoperative Tissue Doppler Imaging-Derived Atrial Conduction Time Predicts Postoperative Atrial Fibrillation in Patients Undergoing Mitral Valve Surgery for Mitral Valve Regurgitation.
CONCLUSIONS: PA-TDI duration was an independent predictor of POAF after MVS. Patients with PA-TDI duration >159.4 ms should be considered high risk and treated appropriately to improve outcome. PMID: 26538374 [PubMed - as supplied by publisher]

Which Patients Are Candidates for Minimally Invasive Mitral Valve Surgery? 　- Establishment of Risk Calculators Using National Clinical Database.
CONCLUSIONS: We developed risk calculator formulas using risk factors associated with both operative mortality and composite outcome. The present risk calculator formula is useful for patient selection and may influence future applications for this procedure. PMID: 31257312 [PubMed - as supplied by publisher]
