This is a compreshensive review on the experience with use of TEVAR in patients with Marfan syndrome, including durablity, complications, and timing, etc. Drs. Steinmetz and Cosellihe also discussed the role and trend of TEVAR in Marfan paitents with aortic disease.

Transcatheter aortic valve replacement (TAVR) is not inferior to surgical aortic valve replacement (SAVR) when it comes to all-cause mortality after one year. This is among moderate-risk patients with severe, symptomatic aortic stenosis (AS). According to a new analysis published in JAMA, a close comparison revealed that each treatment option is associated with certain benefits over the other.

A recent ISCHEMIA trial substudy is under scrutiny from surgeons for a discrepancy in data. This has rekindled concerns about reliance on the landmark trial data in the newest coronary revascularization guidelines. CTSNet recently recently published a webinar on this topic featuring leading CT surgeons around the globe.

Meta-analysis of 119 studies (approx 38,000 patients) evaluating outcomes of minimally invasive mitral valve surgery with conventional sternotomy approach.
MMVS was associated with fewer days in hospital (RCT: MD: -2.2 days, 95% CI, [-3.7 to -0.8]; observational: MD: -2.4 days, 95% CI, [-2.7 to -2.1]). Observational studies suggested that MMVS reduced transfusion requirements with fewer units transfused per patient (MD: -1.2; 95% CI, [-1.6 to -0.9]) and fewer patients transfused (RR, 0.7; 95% CI, [0.6-0.7]). Observational data also suggested lower mortality with MMVS (RR, 0.6; 95% CI, [0.5-0.7], p < .001, I2 = 0%), but this was not corroborated by RCT data. The risk of postoperative mitral regurgitation (≥2+ or requiring re-intervention) did not differ between the two groups.

Data from Scientific Registry of Transplant Recipients was modeled over 30 years to evaluate temporal trends, as well as graft survival.
Among 56,488 primary adult heart recipients, we observed 5529 (9.8%) all-cause deaths and 1933 (3.4%) graft failure events within 6 months posttransplant. Prevalence of known recipient risk factors increased over time. Unadjusted modeling demonstrated a significant 30-year improvement in graft survival, averaging 2.6% per year (95% confidence interval, 2.4-2.9; P for trend < .001). After adjusting for population changes the 30-year trend remained significant and graft survival improved on average 3.0% per year (95% confidence interval, 2.6-3.3). Regression modeling identified multiple predictors of graft survival. Modeling 2 additional outcomes of 6-month mortality and 6-month graft failure produced similar results.

Retrospective review (propensity-matched) comparing patients undergoing PCI vs minimally invasive CABG for complex LAD lesions.
Overall 9-year survival was not significantly different between patient groups both before and after propensity matching. Midterm mortality in the matched minimally invasive direct coronary artery bypass group was low, irrespective of patient risk profile. By contrast, advanced age (hazard ratio, 1.10; P = .012) and obesity (hazard ratio, 1.09; P = .044) predicted increased late death after drug-eluting stent percutaneous coronary intervention among matched patients. Patients who underwent minimally invasive direct coronary artery bypass were significantly less likely to require repeat left anterior descending revascularization than those who had percutaneous coronary intervention, both before and after propensity matching. Smaller stent diameter in drug-eluting stent percutaneous coronary intervention was associated with increased left anterior descending reintervention (hazard ratio, 3.53; P = .005).
