Long-term results after concomitant mitral and aortic valve surgery: repair or replacement?

Objectives: The reported superiority of mitral valve (MV) repair for isolated MV regurgitation has not been confirmed in mitroaortic valve surgery. Our goals were to evaluate the feasibility of repair in patients undergoing mitral and aortic valve surgery and to identify factors predisposing to MV replacement, to compare long-term outcomes (survival and MV reoperation) of repair and replacement and to perform a subgroup analysis in patients with rheumatic MV disease.

Methods: From January 1992 through December 2016, 1122 consecutive patients were submitted to concomitant aortic and MV surgery in 2 different centres (Coimbra and Santiago).

Primary graft failure after cardiac transplantation: prevalence, prognosis and risk factors.

Objectives: Primary graft failure (PGF) is a common and devastating complication, despite the advances in perioperative treatment. We aim to evaluate the prevalence of PGF and its impact on survival and to explore associated risk factors.

Methods: From November 2003 through December 2015, 290 patients submitted to cardiac transplantation were classified into non-PGF (243; 84%) and PGF (47; 16%) groups.

Surgical Treatment of Posterior Mitral Valve Prolapse: Towards 100% Repair.

Background: The study aim was to evaluate the immediate and long-term results of surgical treatment of isolated posterior mitral valve leaflet prolapse (PLP), focusing on survival and freedom from recurrent mitral regurgitation (MR).

Methods: Between January 1998 and December 2012, a total of 492 consecutive patients (375 males, 117 females; mean age 61.8 ± 12.

Long-term follow-up of patients undergoing aortic root enlargement for insertion of a larger prosthesis.

Objectives: To evaluate the long-term survival of patients undergoing aortic root enlargement (ARE) compared with those with small aortic root (SAR), exploring risk factors for late mortality as well as the influence of patient-prosthesis mismatch (PPM).

Methods: From January 1999 through December 2010, a total of 3724 patients underwent isolated or combined aortic valve replacement at our institution. From these, 239 (6.

Long-term results of mitral valve surgery for degenerative anterior leaflet or bileaflet prolapse: analysis of negative factors for repair, early and late failures, and survival.

Objectives: To evaluate the feasibility of mitral valve repair in patients with anterior leaflet (ALP) or bileaflet prolapse (BLP) and identify factors predisposing patients to replacement. To compare long-term survival of patients submitted to repair (Group Repair) against those submitted to replacement (Group Replacement), and investigate causes of early and late failures of repair.

Methods: From January 1992 through December 2012, 768 patients with ALP or BLP were submitted to mitral valve surgery, of whom 501 had degenerative involvement [Myxomatous (Myx)-336 (67.

Mitral valve surgery after percutaneous mitral commissurotomy: is repair still feasible?

Objectives: Due to progression of rheumatic disease, percutaneous mitral commissurotomy (PMC) is a palliative procedure. We aimed at evaluating the outcomes of patients requiring surgery for failure of PMC, focusing on the fate of the mitral valve (MV) (repair versus replacement).

Methods: From January 1993 through December 2012, 61 patients with previous PMC were submitted to MV surgery.

Negative impact of atrial fibrillation and pulmonary hypertension after mitral valve surgery in asymptomatic patients with severe mitral regurgitation: a 20-year follow-up.

Objectives: The timing for mitral valve (MV) surgery in asymptomatic patients with severe mitral regurgitation (MR) and preserved left ventricular (LV) function remains controversial. We aimed at analysing the long-term outcome of asymptomatic patients with atrial fibrillation (AF) and/or pulmonary hypertension (PHT) after successful MV repair.

Methods: From January 1992 to December 2012, 382 patients with severe degenerative MR, with no or mild symptoms, preserved LV function (ejection fraction > 60%) and LV systolic dimensions <45 mm were submitted to surgery and followed up for up to 22 years (3209 patient-years).

Long-term follow-up of asymptomatic or mildly symptomatic patients with severe degenerative mitral regurgitation and preserved left ventricular function.

Objectives: The timing for mitral valve surgery in asymptomatic patients with severe mitral regurgitation and preserved left ventricular function remains controversial. We analyzed the immediate and long-term outcomes of these patients after surgery.

Methods: From January 1992 to December 2012, 382 consecutive patients with severe chronic degenerative mitral regurgitation, with no or mild symptoms, and preserved left ventricular function (ejection fraction ≥ 60%) were submitted to surgery and followed for up to 22 years (3209 patient-years).

Concomitant aortic and mitral surgery: to replace or repair the mitral valve?

Objectives: The study objectives were to evaluate the perioperative outcomes of concomitant mitral and aortic valve surgery and to determine the influence of mitral valve repair versus replacement on survival and adverse events.

Methods: The study population comprised 261 patients with a mean age of 61.3±11.

Management of moderate secondary mitral regurgitation at the time of aortic valve surgery.

Objectives: To define the impact of surgical strategy [concomitant mitral valve surgery or isolated aortic valve replacement (AVR)] in patients with moderate secondary mitral regurgitation (MR) at the time of AVR.

Methods: From January 1999 to December 2009, 3339 patients underwent AVR of whom 255 had secondary MR >2+ and constituted the study population. Patients were stratified into two groups, with (Group A, n = 94, 36.

Aortic root enlargement does not increase the surgical risk and short-term patient outcome?

Objective: To analyze the short-term outcome of aortic root enlargement (ARE) using death and adverse events as end points.

Methods: From January 1999 through December 2009, 3339 patients were subjected to aortic valve replacement (AVR). A total of 678 were considered to have small aortic roots (SARs) in which an aortic prosthesis size 21 mm or smaller was implanted.
