A twenty-nine-day old male infant suffering from critical aortic stenosis underwent aortic valvotomy by cardiopulmonary bypass. At three years of age the aortic stenosis recurred and the child underwent a balloon aortic valvuloplasty, but developed severe aortic insufficiency after the procedure. The critical condition of the patient made aortic valve replacement mandatory. The surgical technique consisted of aortoventriculoplasty with infundibular and valve pulmonary autograft for substituting the aortic root (Ross-Konno technique). As for as we know this is the first report on the Ross-Konno procedure in Spanish journals.

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

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: Severe aortic stenosis (AS) stratified by sex has been increasingly studied in the European population. Sex-specific outcomes in Asian patients with AS remain poorly defined. Hence, we aimed to study the clinical characteristics and impact of sex in moderate-to-severe AS, undergoing both invasive and conservative interventions in an Asian cohort over 10 years.

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.
Raphe-Type Bicuspid Aortic Valve as a Risk Factor for Transcatheter Aortic Valve Replacement Failure: Improving Outcomes Using the LIRA Method and the Medtronic FX Prosthesis.

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.
