Ross Procedure Versus Mechanical Versus Bioprosthetic Aortic Valve Replacement: A Network Meta-Analysis.

Background The Ross operation appears to restore normal survival in young and middle-aged adults with aortic valve disease. However, there are limited data comparing it with conventional aortic valve replacement. Herein, we compared outcomes of the Ross procedure with mechanical and bioprosthetic aortic valve replacement (M-AVR and B-AVR, respectively).

Improved Outcomes of Reimplantation vs Remodeling in Marfan Syndrome: A Propensity-Matched Study.

Background: Valve-sparing root replacement (VSRR) has excellent outcomes when performed in experienced centers in well-selected patients. It is suggested that reimplantation of the aortic valve may have better durability than remodeling in patients with Marfan syndrome (MFS), although long-term comparative data are limited.

Methods: Between 1988 and 2018, 194 patients with MFS underwent VSRR at our institution.

Post-infarction ventricular septal rupture.

Coronary reperfusion therapies have led to a reduction in the incidence of mechanical complications of acute myocardial infarction (AMI), but the associated mortality of these complications has remained high. Ventricular septal rupture is the most common mechanical complication after myocardial infarction and occurs in approximately 0.21% with ST-segment elevation myocardial infarction and in 0.

Sex differences in authorship in cardiothoracic surgery during the early coronavirus disease 2019 pandemic.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic negatively impacted cardiothoracic (CT) surgery, with changes in clinical, academic, and personal responsibilities. We hypothesized that the pandemic may disproportionately impact female academic CT surgeons, accentuating preexisting sex disparities. This study assessed sex differences in authorship of 2 major CT surgery journals during the early part of the COVID-19 pandemic.

Improved Outcomes Following the Ross Procedure Compared With Bioprosthetic Aortic Valve Replacement.

Background: The ideal aortic valve substitute for young and middle-aged adults remains elusive.

Objectives: This study sought to compare the long-term outcomes of patients undergoing the Ross procedure and those receiving bioprosthetic aortic valve replacements (AVRs).

Methods: Consecutive patients aged 16-60 years who underwent a Ross procedure or surgical bioprosthetic AVR at the Toronto General Hospital between 1990 and 2014 were identified.

Outcomes of combined aortic and mitral valve replacement with reconstruction of the fibrous skeleton of the heart.

Objectives: The objectives of this study were to examine operative and long-term results of combined aortic and mitral valve replacement when reconstruction of the fibrous skeleton of the heart is needed because of calcification, abscess, previous operations, or patient-prosthesis mismatch.

Methods: From 1985 to 2020, 182 consecutive patients underwent combined aortic and mitral valve replacement with reconstruction of the intervalvular fibrous skeleton in all cases and also the posterior mitral annulus in 63 patients. Bovine pericardium or Dacron grafts were used for the reconstructions.

A progress report on reimplantation of the aortic valve.

Objective: To examine the late outcomes of reimplantation of the aortic valve (RAV) in patients followed prospectively since surgery.

Methods: All 465 patients who had RAV from 1989 to 2018 were followed prospectively with periodic clinical and echocardiographic assessments. Mean follow-up was 10 ± 6 years and 98% complete.

Perspectives on surgical treatment of mitral valve disease.

A sound knowledge of the functional anatomy of the mitral valve and the alterations caused by different diseases is indispensable for surgeons treating patients with mitral valve disease. Rheumatic mitral valve disease remains the most common heart valvular disorder in developing countries, whereas mitral regurgitation due myxomatous degeneration of the valve is the most common in developed countries. The mitral valve should be repaired whenever possible, as long as the outcome is predictably better than that of replacement.

A systematic review and meta-analysis of the effects of antenatal anxiety on postpartum outcomes.

To systematically review and meta-analyze research investigating the association between maternal anxiety during pregnancy and outcomes for mother and baby following the immediate delivery period. MEDLINE, Medline In-Process & Other Non-Indexed Citations, PsycINFO, Embase, CINAHL, and the Cochrane library were searched. English-language, prospective studies providing data on outcomes following delivery in women with and without antenatal anxiety (defined by clinical diagnosis or score on validated scale) were included.

Late results of the Ross procedure.

Objective: The study objective was to examine the long-term results of the Ross procedure in a cohort of patients followed prospectively for more than 2 decades.

Methods: From 1990 to 2004, 212 consecutive patients with a median age (interquartile range) of 34 years (28-41) underwent the Ross procedure; 82% had congenital aortic valve disease. The technique of aortic root replacement was used in one half of the patients.

Deletion size analysis of 1680 22q11.2DS subjects identifies a new recombination hotspot on chromosome 22q11.2.

Recurrent, de novo, meiotic non-allelic homologous recombination events between low copy repeats, termed LCR22s, leads to the 22q11.2 deletion syndrome (22q11.2DS; velo-cardio-facial syndrome/DiGeorge syndrome).

A neurogenetic model for the study of schizophrenia spectrum disorders: the International 22q11.2 Deletion Syndrome Brain Behavior Consortium.

Rare copy number variants contribute significantly to the risk for schizophrenia, with the 22q11.2 locus consistently implicated. Individuals with the 22q11.
