Unlabelled: Between 1976 and 1984, 182 patients over 60 years with valvular defects were examined invasively and valve replacement was performed. 34 patients (19%) were older than 70 years. Hospital mortality was 2% in aortic valve replacement, 4% in mitral valve and 8% in double valve replacement. Overall early mortality in patients between 60 and 70 years of age was 3.4% and 6% in patients over 70 years for all operations. Simultaneous aortocoronary bypass surgery did not enhance the operation risk. During the follow-up period of 23 +/- 22 months a total of 21 patients died (12%). Only 4% of the survivals showed clinical deterioration by at least one NYHA class. Clinical tendency to improvement was as clearly evident among the patients of over 70 years of age as among the entire group. Preoperative invasive and noninvasive data do not display any significant correlation with the result of surgery. Significantly higher (P less than 0.05) mortality rates or inferior functional operation results were seen only with higher age, a preceding valve operation, and preoperative NYHA class IV.
Conclusion: In elderly patients indication for valve replacement should not be more restrictive than in younger ones. Postponement of valve replacement in these age groups until the patient experiences symptoms when at rest (NYHA class IV) will adversely affect the chances of success and increase the mortality risk.

Platform Selection for Patients Undergoing Transcatheter Aortic Valve Replacement: A Practical Approach.
Catheter Cardiovasc Interv

IRCCS Pol. S. Donato, Milan, Italy.
Transfemoral transcatheter aortic valve Replacement (TAVR) has become the standard therapy for patients with severe aortic stenosis in patients over 75 years old in Europe or 65 years old in the United States, regardless of the surgical risk. Furthermore, iterations of existing transcatheter aortic valves (TAVs), as well as devices with novel concepts, have provided substantial improvements with respect to the limitations of previous-generation devices. Hence, treatment of a broader spectrum of patients has become feasible, and a sophisticated selection of the appropriate TAV tailored to patients' anatomy and comorbidities is now possible.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Background: A staging system based on cardiac damage for severe aortic stenosis (AS) has been validated for prognosis prediction following transcatheter aortic valve replacement (TAVR). Our study aims to investigate whether TAVR can lead to changes in cardiac damage shortly after the procedure and how these changes impact prognosis.
Method: Patients in this retrospective cohort study were classified into five stages (0-4) before TAVR based on the echocardiographic findings of cardiac damage.

The use of extracorporeal membrane oxygenation (ECMO) has emerged as a rescue intervention for hemodynamically unstable patients and prophylactic intraprocedural hemodynamic support in the cardiac catheterization laboratory. The prompt initiation of ECMO provides immediate hemodynamic support and allows for the completion of bridging and/or life-saving interventions. However, there are no clinical practice guidelines for the use of extracorporeal support in this area.

Transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis and raphe-type bicuspid aortic valve (BAV) is still associated with poor outcomes in terms of increased risk of paravalvular regurgitation, stroke, and permanent pacemaker implantation. There is no definitive consensus on the optimal sizing method for prosthesis selection in this setting. The LIRA method is a supra-annular tailored sizing method specifically designed for bicuspid anatomy that might increase accuracy of prosthesis choice in BAV patients and improve TAVR outcomes.
