Preoperative left atrial volume index is associated with postoperative outcomes in mitral valve repair for chronic mitral regurgitation.
Parvathi Balachandran,Hartzell V. Schaff,Brian D. Lahr,Anita Nguyen,Richard C. Daly,Simon Maltais,Sorin V. Pislaru,Joseph A. Dearani +7 more
TL;DR: In patients with degenerativeMitral valve regurgitation who had mitral valve repair, preoperative left atrial volume index was associated with extent of left atri reverse remodeling, risk of early postoperative atrial fibrillation, and late mortality.

Conventional redo biological valve replacement over 20 years: Surgical benchmarks should guide patient selection for transcatheter valve-in-valve therapy.
John M. Stulak,Vakhtang Tchantchaleishvili,Richard C. Daly,Mackram F. Eleid,Kevin L. Greason,Joseph A. Dearani,Lyle D. Joyce,Alberto Pochettino,Hartzell V. Schaff,Simon Maltais +9 more
TL;DR: This study could serve as a surgical benchmark to guide patient selection for transcatheter valve‐in‐valve technology rather than employing a broader application of these techniques to those who may otherwise have low early risk of mortality and durable long‐term survival after conventional valve surgery.

A method of repair for asymmetric aneurysmal dilatation of the ascending aorta.
TL;DR: This paper reports an alternate method of resection of asymmetric aneurysmal dilatation of the ascending aorta with primary end-to-end anastomosis that requires only one suture line and theoretically reduces the risk of bleeding.

Risk of conventional cardiac surgery among patients with severe left ventricular dysfunction in the era of mechanical circulatory support.
Nassir M. Thalji,Simon Maltais,Richard C. Daly,Kevin L. Greason,Hartzell V. Schaff,Shannon M. Dunlay,John M. Stulak +6 more
TL;DR: In patients referred for conventional surgery with an ejection fraction ≤ 25%, prior cardiac surgery, and/or NYHA functional class IV symptoms—particularly in those aged ≥ 70 years—confer significant and sustained survival disadvantages.

A cost-effective technique for experimental coronary artery bypass.
TL;DR: A method for experimental coronary artery bypass that uses a temporary silicone rubber shunt from the subclavian artery to the circumflex coronary artery to maintain blood flow to the distal myocardium is described.
