Letter to the Editor Ross procedure valve function, clinical outcomes and predictors after 25 years follow up.

The following letter presents an answer of a comment of our work titled "Ross procedure: valve function, clinical outcomes and predictors after 25 years' follow-up," recently published in your journal by Rangwala et al. As our colleagues point out, the Ross procedure has excellent survival rates but a significant risk of valve dysfunction and therefore reintervention at follow-up. Although the survival advantage with the Ross procedure appears to be consistent compared with mechanical valve substitutes, this benefit is not as clear compared with biological valve substitutes.

Ross procedure: valve function, clinical outcomes and predictors after 25 years' follow-up.

Objective: To describe long-term outcomes of the Ross procedure in a single center and retrospective series after 25 years follow-up.

Methods: From 1997-2019 we included all consecutive patients who underwent Ross procedure at our center. Clinical and echocardiographic evaluations were performed at least yearly.

Pulmonary homograft stenosis in the Ross procedure: Incidence, clinical impact and predictors in long-term follow-up.

Background: The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known.

Aim: To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital.

Autograft failure during follow-up after the Ross procedure: predictive factors in a prospective series.

To determine the incidence of, and predictive factors for, aortic autograft failure during follow-up after the Ross procedure. Of 102 consecutive patients who underwent surgery at our centre between 1997 and 2009, we selected 83 (age 32+/-11 years), all of whom had been discharged without significant autograft regurgitation and for whom at least one follow-up echocardiogram was available. Autograft failure was defined as the presence of at least moderate regurgitation on echocardiography.

Arterial switch operation with separate coronary arteries arising from a single aortic sinus.

In some patients, the coronary arteries originate in a single aortic sinus, and this anatomical configuration is regarded as a significant risk factor in the arterial switch operation for transposition of the great arteries. In these cases, the coronary transfer technique has to be individualized to suit the coronary anatomy (i.e.

Bronchial artery aneurysm treated with aortic stent graft and fibrin sealant.

Bronchial artery aneurysm occurs rarely but can cause a life-threatening hemorrhage when it ruptures. The traditional therapy has been aneurysm resection or transcatheter arterial embolization. We report a case of mediastinal bronchial artery aneurysm which could not be occluded with transcatheter arterial embolization and instead was treated with a thoracic aortic stent graft and embolization with fibrin sealant.

Effect of cardiac resynchronization on the incidence of atrial fibrillation in patients with severe heart failure.

Background: Atrial fibrillation/flutter (AF) and heart failure often coexist; however, the effect of cardiac resynchronization therapy (CRT) on the incidence of AF and on the outcome of patients with new-onset AF remains undefined.

Methods And Results: In the CArdiac REsynchronisation in Heart Failure (CARE-HF) trial, 813 patients with moderate or severe heart failure were randomly assigned to pharmacological therapy alone or with the addition of CRT. The incidence of AF was assessed by adverse event reporting and by ECGs during follow-up, and the impact of new-onset AF on the outcome and efficacy of CRT was evaluated.

Prospective evaluation of aortic valve replacement in young adults and middle-aged patients: mechanical prosthesis versus pulmonary autograft.

Background And Aim Of The Study: The best option for aortic valve replacement (AVR) in young adults and middle-aged patients remains controversial. A longitudinal comparison between the Ross procedure (RP) and mechanical prosthesis (MP) was conducted in this group of patients.

Methods: Between January 1997 and January 2003, 125 consecutive patients (age range: 20-50 years) were submitted for AVR; 62 patients (mean age 37.

The Ross procedure.

Background: The search for the ideal substitute for the aortic valve led Donald Ross to develop the pulmonary autograft concept in 1967. A historical, technical, and scientific review of this surgical option is presented together with our clinical experience.

Materials And Methods: The literature is reviewed to identify the advantages and pitfalls of the Ross procedure over the last decades.

[Short-term results with the ross procedure. Does the etiology of aortic valvulopathy affect the outcome?].

Introduction: The Ross procedure has become established as an appropriate method for aortic valve replacement in children and young adults. There is controversy regarding the results of this surgical technique depending on whether the aortic valve disorder is congenital or acquired. The objective of this study was to analyze the outcome of this technique in different etiologies.

Mitral homograft in the tricuspid position, aortic homograft and mitral plasty in a drug addict with multiple valve endocarditis.

The case is reported of multiple valve surgery using as little prosthetic material as possible in a drug addict with recurrent right and left bacterial endocarditis. The patient underwent aortic valve replacement with a cryopreserved aortic homograft, mitral repair and tricuspid valve replacement with a mitral homograft, using a modified technique. The indications and surgical options for tricuspid valve endocarditis in this patient group are discussed, with particular focus on technical aspects of using mitral homografts in the tricuspid position.
