Prosthesis-patient mismatch affects late survival after valve surgery for severe aortic stenosis.

Background: The effect of prosthesis-patient mismatch (PPM) on late survival after aortic valve replacement (AVR) in patient with symptomatic severe aortic stenosis (AS) remains unclear. Also, late follow-up in previous studies is confined to only one decade. We aimed to determine the effect of PPM on late survival after isolated AVR for symptomatic severe AS during 25 years of follow-up.

Effect of aortic cross-clamp time on late survival after isolated aortic valve replacement.

Objectives: Longer aortic cross-clamp (ACC) time is associated with decreased early survival after cardiac surgery. Because maximum follow-up in previous studies on this subject is confined to 28 months, it is unknown whether this adverse effect is sustained far beyond this term. We aimed to determine whether longer ACC time was independently associated with decreased late survival after isolated aortic valve replacement in patients with severe aortic stenosis during 25 years of follow-up.

New-onset postoperative atrial fibrillation after aortic valve replacement: Effect on long-term survival.

Objective: There is a paucity of data on long-term survival of new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. Also, mean follow-up in previous studies is confined to a maximum of one decade. This retrospective, longitudinal cohort study was performed to determine the effect on long-term survival of new-onset POAF after aortic valve replacement (AVR) over a mean follow-up of almost 2 decades.

Prosthesis-Patient Mismatch After Aortic Valve Replacement: Effect on Long-Term Survival.

Background: Mean follow-up in previous studies on the effect of prosthesis-patient mismatch on long-term survival after aortic valve replacement (AVR) is confined to a maximum of one decade. This retrospective longitudinal cohort study was performed to determine the effect on long-term survival of prosthesis-patient mismatch after AVR with a mean follow-up of almost two decades.

Methods: Kaplan-Meier survival analysis was used to determine long-term survival after AVR in a cohort of 673 consecutive patients, divided into 163 patients (24.

Can late supraclavicular echo Doppler reliably predict angiographical string sign of lima to lad area grafts?

Objective: To investigate whether supraclavicular ultrasonography of left internal mammary artery (LIMA) to left anterior descending (LAD) area grafts can reliably predict (distal) string sign grafts on arteriography.

Methods: Fifty-five patients (42 M, 61 +/- 7 years) with the LIMA to LAD area grafting were prospectively studied. Control arteriography was performed at 1.

The elephant trunk technique: operative results in 100 consecutive patients.

Objectives: To describe morbidity and mortality in patients undergoing the elephant trunk (ET) implantation as the first stage in the repair of their mega aorta and to assess determinants for the occurrence of complications.

Methods: One hundred consecutive patients undergoing an ET implantation between 1984 and June 2001 were retrospectively analyzed. The ET was implanted as an extension of an isolated aortic arch (1%), an aortic valve replacement+ascending aorta+arch (14%), a root replacement+ascending aorta+arch (37%) and an ascending aorta+arch (48%).
