A technique for complete replacement of the aortic valve and ascending aorta in cases of aneurysm of the ascending aorta with aortic valve ectasia is described. The proximal aortic root was too attenuated to afford anchorage to the aortic prosthesis, so this was sutured to the ring of a Starr valve and the prostheses were inserted en bloc. The ostia of the coronary arteries were anastomosed to ...

BACKGROUND The objective was to evaluate the effects of aortic annulus size on valve hemodynamics and clinical outcomes in those patients included in the Placement of Aortic Transcatheter Valves (PARTNER) randomized controlled trial cohort A and the nonrandomized continued access cohort. METHODS AND RESULTS Patients included the randomized controlled trial (n=574) and nonrandomized continued ...

OBJECTIVE After aortic valve replacement, the effects of a small functional prosthesis on the extent and pattern of regression of left ventricular hypertrophy and on clinical outcomes may be less significant in older patients with low cardiac output requirements. The objective of this study was therefore to determine whether patient-prosthesis mismatch affects left ventricular mass regression i...

INTRODUCTION AND OBJECTIVES The clinical impact of patient-prosthesis mismatch on the outcome in octogenarians who undergo surgery for aortic valve replacement due to severe stenosis is unknown. Our objective was to quantify the frequency of some degree of patient-prosthesis mismatch and its impact on mortality and life quality. METHODS We analyzed all the octogenarian patients who underwent ...

BACKGROUND Small aortic prosthesis can lead to prosthesis-patient mismatch (PPM). Implanting such small prosthesis remains a controversial issue. This study was done to investigate whether or not PPM causes an increased operative mortality in aortic valve replacement (AVR). METHODS Two-hundred-two consecutive patients undergoing primary AVR in a tertiary hospital were included. The sample was...

BACKGROUND The inflammatory process in aortic valvular stenosis persists after surgery to replace the valve in almost half of the patients. No association has been found to its persistence. The main objective of this study was to evaluate the inflammatory response in patients with aortic stenosis through the determination of several biomarkers in plasma measured before and after the valvular re...

Dehiscence of the valve is a serious complication of prosthetic heart valve replacement. It has grave consequences unless promptly diagnosed and corrected by surgery. We report the case of a symptomless patient with near-complete detachment of the aortic prosthesis, diagnosed by radiography and two-dimensional echocardiography. This was confirmed at surgery and the dehisced prosthetic valve was...

A 53-year-old woman who had undergone aortic valve replacement with a Starr-Edwards (S-E) valve (Model 1260) and open mitral commissurotomy 28 years previously was hospitalized with cardiac failure. Echocardiography showed mitral stenosis, mitral regurgitation, and a normally functioning S-E prosthesis. At reoperation, the mitral and aortic valves were replaced with St Jude bileaflet mechanical...

Prosthesis-patient Mismatch (PPM) is not uncommon with an incidence reported up to 70% after aortic valve (AV) replacement. Severe forms of PPM are less common (up to 20%); PPM can lead to increased short- and long-term morbidity and mortality. It is important to discriminate PPM from other forms of prosthetic valve dysfunction. Sometimes, prosthetic valve degenerative disease may coexist with ...
