Mitral valve repair for mitral regurgitation (MR) is currently recommended based on the degree of MR and left ventricular (LV) function. The present study examines predictors of reverse remodeling after repair for degenerative disease. We retrospectively identified 439 patients who underwent repair for myxomatous mitral valve degeneration and had both pre- and postoperative echocardiographic data available. Patients were categorized based on left atrial (LA) diameter and LV diameter standards of the American Society of Echocardiography. The outcome of interest was the degree of reverse remodeling on all heart dimensions at follow-up. Mean age was 57 ± 12 years, and 37% of patients were women. Mean preoperative LV end-diastolic diameter was 5.8 ± 0.7 cm, LV end-systolic diameter 3.5 ± 0.6 cm, LA 4.7 ± 0.7 cm, and median ejection fraction 60%. Median observation time was 81 months, and time to postoperative echocardiography was 38 months. Overall, 95% of patients had normal LV diastolic dimensions postoperatively, 93% normal LV systolic dimensions, and 37% normal LA dimensions. A Cox regression analysis showed that moderate (odds ratio [OR] 2.1, 95% confidence interval [CI] 1.3 to 3.4) or severe preoperative LA dilatation (OR 2.7, 95% CI 1.7 to 4.4), abnormal preoperative LV end-systolic dimensions (OR 1.3, 95% CI 1.1 to 1.5), and age in years (OR 1.02, 95% CI 1.01 to 1.03) were predictive of less reverse remodeling on follow-up. In conclusion, preoperative LV end-systolic dimensions and LA dilatation substantially affect the likelihood of successful LA remodeling and normalization of all heart dimensions after mitral valve repair for MR. These findings support early operation for MR before the increase in heart dimensions is nonreversible.

Studies have shown improved outcomes among married patients who underwent cardiovascular surgery; however, this has not been well studied in transcatheter aortic valve implantation (TAVi). We examined the impact of marital status and patient sex on outcomes after TAVi. Patients who underwent TAVi from January 2015 to June 2018 were reviewed and stratified into 3 groups: single, married, and widowed. The impact of marital status and sex on 30-day outcomes was assessed using a stepwise logistic regression analysis. Cumulative survival was estimated using Kaplan–Meier analysis and adjusted survival with multivariable Cox proportional hazards modeling. A total of 785 patients were included: 149 single, 413 married, and 223 widowed. Widowed patients were older (84 vs 79 years) with higher Society of Thoracic Surgeons risk scores (6.79% vs 5.51%, both p ≤0.001) than married patients. Neither marital status nor sex was associated with 30-day mortality or home discharge. However, 1-year survival revealed a differential survival penalty, with married females (p = 0.041) having lower survival and married males (p = 0.007) having higher survival than their single counterparts. This survival penalty persisted in the adjusted analyses (married females hazard ratio [HR] 2.24, p = 0.009; widowed males HR 2.42, p = 0.057). For patients who were readmitted in the first year, adjusted analysis showed widowed status was associated with higher 30-day readmissions (HR 1.91, p = 0.012) in both sexes. In conclusion, these findings suggest that marital status does not impact both sexes equally after TAVi; identifying at-risk patients and targeted interventions, such as adjusting discharge planning to ensure adequate home social support, may help improve outcomes.

OBJECTIVES Mitral valve repair (MVP) is the gold standard treatment for degenerative mitral regurgitation. With the expansion of transcatheter technologies, this study compares the outcome of MVP in low-risk and non-low-risk patients to serve as a benchmark. METHODS This retrospective, single-institution study examined all patients who underwent MVP for primary mitral regurgitation from 2005 to 2018. Patients were stratified into 2 risk categories: low-risk [Society of Thoracic Surgeons (STS) Predicted Risk of Mortality (STS-PROM) ≤2%] and non-low risk (STS-PROM > 2% or age > 75), with a subgroup of very low risk (STS-PROM ≤1%, age <75). RESULTS A total of 1207 patients were included, and 1053 patients were classified as low risk and 154 as non-low risk. The non-low-risk group was significantly older, more likely to be female, and had a higher comorbidity burden than the low-risk group (all P < 0.01). For the low-risk group, the observed-to-expected (O:E) STS mortality ratio was 0.4 and the composite morbidity and mortality ratio was 0.6, whereas for the non-low risk, the O:E mortality was 1.5 and the composite morbidity and mortality was 0.9. When the subgroup of very low-risk group was assessed, the mortality O:E ratio was 0. CONCLUSIONS The observed composite morbidity and mortality of patients undergoing MVP were persistently lower in low-risk patients, mainly driven by the very low-risk group. The excellent outcome of MVP in low-risk patients should be validated on a national level to determine how transcatheter technologies can be utilized in these patients.

Background: Severe calcific disease of the ascending aorta may prohibit cross‐clamping during coronary artery bypass grafting (CABG) due to unacceptable morbidity and mortality associated with atheroembolic complications. Clampless hypothermic noncardioplegic low flow fibrillation (HLFF) may minimize neurologic complications while allowing for complete revascularization. Methods: From 2002 to 2019, 142 patients with unclampable aorta (UCA) underwent isolated CABG using clampless HLFF. Short‐term and long‐term outcomes were compared with an isolated conventional on‐pump CABG cohort ( n = 268) risk‐matched (RM) for type of CABG, STS score, age, and sex. Results: UCA and RM cohort patients were comparable in terms of age (73.7 ± 7.8 vs. 72.7 ± 8.7, p = 0.281), sex (34.4% vs. 32.5% female, p = 1.000), STS score (4.01 ± 3.43 vs. 3.80 ± 3.33, p = 0.539), and number of diseased vessels ( p = 0.323). 90% of patients underwent central cannulation; UCA group patients received a comparable number of arterial ( p = 0.432) or venous grafts ( p = 0.493). Incidence of stroke was 6.3% in the UCA cohort and 2.6% in the RM cohort ( p = 0.059). Need for reoperation, postoperative transfusions, incidence of atrial fibrillation, and renal impairment was similar (all p > 0.050). UCA patients spent a longer time on the ventilator, in the ICU, and in the hospital (all p = 0.001). Operative mortality was not different between UCA and RM groups (3.5% vs. 4.5%, p = 0.797) as was all‐cause mortality over long‐term follow‐up ( p = 0.093). Conclusions: While a higher incidence of stroke was observed, without reaching statistical significance, hypothermic fibrillatory arrest remains a valuable and safe tool for coronary revascularization in UCA patients, offering comparable short‐term and long‐term survival outcomes allowing for complete revascularization.

Outcomes after mitral valve (MV) repair are known to be worse in women. Less is known about sex-based differences in MV repair durability. All adult patients undergoing MV repair from 2002 to 2016 were reviewed. Of 2463 cases, 947 (39%) were women. Re-operation risk was defined as any intervention for repair failure or MV disease progression. Median follow-up was 8.2 years. Women were older with higher STS-risk scores and were more likely to have rheumatic disease (RHD). Operative mortality was clinically higher in women (2.7% vs 1.7%; P = 0.09). Although women had significantly higher 10-year re-operation risk (7% vs 4%), adjusted longitudinal analysis showed that this was associated with RHD in women (HR 4.04; P = 0.001). Female sex alone was not a significant predictor (P = 0.21). Re-operation following MV repair was infrequent. Women had increased re-operation risk that was largely attributable to their worse preoperative profiles rather than female sex alone.

Interstitial lung disease (ILD) is a known risk factor for noncardiac surgery due to acute pulmonary exacerbations but its impact after cardiac surgery is not known. We examined perioperative outcomes and risk factors for long-term survival in ILD patients who underwent cardiac surgery. From January 2002 to June 2017, 294 cardiac surgery patients with a previous ILD diagnosis, including 75 patients with idiopathic pulmonary fibrosis (IPF), were identified. A comparison cohort of 1,481 non-ILD patients was selected based on a priori variables. Long-term survival was evaluated using Cox proportional hazard modeling. Median follow-up was 6.4 years. ILD patients had higher postoperative mortality, reintubation rates, longer intensive care unit stay, and higher 30-day readmission rates (all p <0.05). Kaplan-Meier estimates of survival at 1, 5, and 10 years were 89%, 62%, and 37% for the non-IPF ILD cohort, 89%, 50%, and 13% for the IPF cohort, and 95%, 82%, and 67% for the comparison cohort, respectively (overall p <0.001). These significant differences in survival persisted in our risk-adjusted survival analysis. Adjusted survival analysis identified IPF (hazard ratio 3.04) and ILD (non-IPF; hazard ratio 1.78) as significant contributors to all-cause mortality. However, there were no changes in pulmonary function tests after 48 months postprocedure. In conclusion, ILD patients who underwent cardiac surgery have increased operative mortality, reintubation rates, longer intensive care unit, and higher 30-day readmissions compared with non-ILD patients. Moreover, severity of ILD, especially in IPF, appears to be associated with shorter long-term survival. In these patients, pulmonary risk stratification and multidisciplinary team approach are crucial. [Display omitted]

Surgical aortic valve replacement (SAVR) in patients with porcelain aorta is considered a high-risk procedure. Hence, transcatheter aortic valve implantation (TAVI) is emerging as the intervention of choice. However, there is a paucity of data directly comparing TAVI with SAVR in patients with porcelain aorta. We compared outcomes of TAVI versus SAVR in high-risk patients with porcelain between March 2012 and June 2015. The TAVI group included 54 patients, whereas 130 SAVR patients with porcelain aorta were identified (operated on between 2004 and 2015). Both groups were matched 1:1 based on the Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) score with a 0.5% a priori caliper, resulting in 52 matched pairs. The mean STS-PROM was 7.3 ± 3.9 for both groups (p = 0.98), whereas mean age was 77.5 years for TAVI and 78.8 years for SAVR (p = 0.46). Compared with SAVR, TAVI patients had lower operative mortality (3.8% vs 17.3%; p = 0.052), significantly shorter median intensive care unit (40 vs 107 hours; p < 0.001) and hospital (5 vs. 7 days; p < 0.001) length of stay (LOS), but similar postoperative stroke rates (7.7% vs 11.5%; p = 0.74). One-year unadjusted survival was 81.7% (95% confidence interval [CI]: 69.8% to 93.5%) in the TAVI group versus 71.2% (95% CI: 61.0% to 85.1%) in the SAVR group, p = 0.093. Cox proportional hazard modeling identified preoperative chronic kidney disease (hazard ratio: 2.63 [95% CI: 1.03 to 6.70]; p = 0.043) and SAVR (hazard ratio: 2.641 [95% CI: 1.07 to 6.51]; p = 0.035) as significant predictors for decreased survival. Overall, TAVI was associated with reduced operative mortality, increased survival, and shorter intensive care unit and hospital length of stay compared with SAVR in patients with porcelain aorta. This study demonstrates that TAVI is a safe intervention in this high-risk population.

Background This study examines the cost effectiveness of group follow-up after participation in the Dose Adjustment for Normal Eating (DAFNE) structured education programme for type 1 diabetes. Methods Economic evaluation conducted alongside a cluster randomised controlled trial involving 437 adults with type 1 diabetes in Ireland. Group follow-up involved two group education ‘booster’ sessions post-DAFNE. Individual follow-up involved two standard one-to-one hospital clinic visits. Incremental costs, quality-adjusted life years (QALYs) gained and cost effectiveness were estimated at 18 months. Uncertainty was explored using sensitivity analysis and by estimating cost effectiveness acceptability curves. Results Group follow-up was associated with a mean reduction in QALYs gained of 0.04 per patient ( P value, 0.052; 95% CI, −0.08 to 0.01, intra-class correlation (ICC), 0.033) and a mean reduction in total healthcare costs of €772 ( P value, 0.020; 95% CI, −1,415 to −128: ICC, 0.016) per patient. At alternative threshold values of €5,000, €15,000, €25,000, €35,000, and €45,000, the probability of group follow-up being cost effective was estimated to be 1.000, 0.762, 0.204, 0.078, and 0.033 respectively. Conclusions The results do not support implementation of group follow-up as the sole means of follow-up post-DAFNE. Given the reported cost savings, future studies should explore the cost effectiveness of alternative models of group care for diabetes.
