Functional Insufficiency of Mitral and Tricuspid Valves Associated With Atrial Fibrillation: Impact of Postoperative Atrial Fibrillation Recurrence on Surgical Outcomes
CONCLUSION: Among patients undergoing surgery for functional atrioventricular insufficiency associated with AF, a significant proportion showed recurrence of AF over time after concomitant AF ablation, which was significantly associated with poor clinical outcomes.PMID:37525492 | DOI:10.4070/kcj.2022.0355

Contribution of Three-Dimensional Transesophageal Echocardiography to Diagnosis and Management of Thrombosis of a St. Jude Mechanical Prosthesis in the Aortic Valve Position
Prosthetic valve thrombosis (PVT) is a serious complication after cardiac valve replacement and usually requires urgent management with either thrombolysis or surgery. A 38-year-old woman with history of ischemic stroke and multiple valvular surgeries including aortic St. Jude mechanical valve replacement (St. Jude Medical, St. Paul, Minnesota) presented with new-onset dyspnea on exertion. Transthoracic echocardiography and 2-dimensional transesophageal echocardiography (TEE) suggested an abnormally high gradient across the aortic valve () but could not determine the cause of the stenosis (, ). Three-dimensional (3D) TEE...

Lack of definite indication criteria for choosing between transcatheter implantation and surgical replacement of the aortic valve
Conclusion: Age and logistic Euroscore might be inadequate criteria for the identification of patients with severe aortic stenosis unsuitable for AVR and addressable to TAVI.

Two‐ and Three‐Dimensional Transthoracic Echocardiography in the Assessment of Aortic Arch Vasum Vasi to Pulmonary Artery Fistula
We report an elderly patient presenting with a stroke and also hemolytic anemia secondary to mitral and tricuspid valve repair 3 years earlier, in whom two‐dimensional transesophageal echocardiography (2DTEE) suspected a fistula into the pulmonary artery (APAF) from the posterior wall of the aortic arch. For further assessment, two‐dimensional transthoracic echocardiography (2DTTE) and live/real time three‐dimensional transthoracic echocardiography (3DTTE) were performed. 2DTTE showed findings similar to 2DTEE. Color Doppler guided continuous‐wave Doppler showed continuous flow throughout the cardiac cycle with sy...

Transcatheter Aortic Valve Replacement: Current Developments, Ongoing Issues, Future Outlook
Since the first clinical implantation in 2002, transcatheter aortic valve implantation or transcatheter aortic valve replacement (TAVR) has become an established therapy in the treatment of symptomatic severe aortic stenosis in patients deemed too high risk for surgical aortic valve replacement. With over 50,000 implants performed in more than 40 countries, a large amount of clinical data have emerged in this rapidly growing field. Careful patient selection, systematic risk stratification, optimal valve sizing, meticulous procedural techniques, and complications management are all important elements to achieve good outcome...

ACC: Surgery, TAVR Equal Long-Term (CME/CE)
(MedPage Today) -- SAN FRANCISCO - There's no long-term difference in rates of stroke or death whether patients have aortic valve repair done surgically or transcatheterally, but mortality is high in both groups, researchers reported here.

Accentuated left ventricular lateral wall function compensates for septal dyssynchrony after valve replacement for aortic stenosis
Abstract: Background: The interventricular septal motion becomes reversed after aortic valve replacement (AVR) for aortic stenosis (AS) despite maintained stroke volume (SV). We hypothesis that left ventricular (LV) lateral wall compensates for such disturbances, in order to secure normal SV.Methods: We studied 29 severe AS patients (age 63±11years, 18 males) with normal ejection fraction (EF) before, 6months and 12months after AVR and compared them with 29 age- and gender-matched controls, using speckle tracking echocardiography.Results: In patients, the LVEF and SV remained unchanged throughout. Before AVR, the septal r...

Transcatheter Aortic Valve Implantation for Pure Severe Native Aortic Valve Regurgitation
ConclusionsThis registry analysis demonstrates the feasibility and potential procedure difficulties when using TAVI for severe NAVR. Acceptable results may be achieved in carefully selected patients who are deemed too high risk for conventional surgery, but the possibility of requiring 2 valves and leaving residual aortic regurgitation remain important considerations.
