Transcatheter Aortic Valve Replacement Improves Quality of Life and Ventricular Function With Low-Flow/Low-Gradient Aortic Stenosis.

Background: D2 aortic stenosis (AS) is the highest risk AS subtype with worse operative and mortality outcomes. This study aimed to investigate the quality of life (QoL) and left ventricular ejection fraction (LVEF) in patients with classic (D2 subtype) low-flow/low-gradient AS who underwent transcatheter aortic valve replacement (TAVR). Methods: In total, 634 patients with severe AS underwent TAVR at our institution from 2014 to 2020, of whom 76 met criteria for classic D2 AS with reduced LVEF. Echocardiographic and clinical outcomes including mortality, stroke, pacemaker placement (PPM), and readmission at baseline were compared with those at 30 days and 1 year. QoL data were extracted from the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Results: The average baseline Society of Thoracic Surgeons risk score for patients with D2 AS was 7.66 ± 6.76. Patients with D2 AS reported improved QoL post-TAVR. The average baseline KCCQ-12 score was 39.5 ± 20, with improvement to 68.9 ± 20.6 at 30 days (P < .01) and 74.9 ± 17.5 at 1 year (P < .01). Mortality was 0% at 30 days and 18.4% at 1 year. The average baseline LVEF was 36.1 ± 9.4. Left ventricular function improved to 43.5 ± 12.9 (P <.001) at 30 days and 46.3 ± 11.2 (P = .03) at 1 year. Complications post-TAVR at 30 days included stroke (1.3%) and PPM (11.8%). Patients with D2 AS exhibited higher baseline conduction defects including atrial fibrillation and higher postoperative PPM than those with other subtypes. Conclusions: Patients with D2 AS had significantly improved LVEF and QoL following TAVR at 30 days and 1 year. Postoperative rates of new PPM were higher than other subtypes, while stroke, dialysis, and mortality were lower than expected, supporting the benefit of TAVR in this high-risk group.

Rural Melanoma Patients Have Less Surgery and Higher Melanoma-Specific Mortality.

BACKGROUND: Melanoma causes most skin cancer-related deaths, and disparities in mortality persist. Rural communities, compared to urban, face higher levels of poverty and more barriers to care, leading to higher stage at presentation and shorter survival in melanoma. To further evaluate these disparities, we sought to assess the association between rurality and melanoma cause-specific mortality and receipt of recommended surgery in a national cohort. METHODS: Patients with primary non-ocular, cutaneous melanoma from the SEER database, 2000-2017, were included. Outcomes included melanoma-specific survival and receipt of recommended surgery. Rurality was based on Rural-Urban Continuum Codes. Variables included age, sex, race, ethnicity, income, and stage. Multivariate regression models assessed the effect of rurality on survival and receipt of recommended surgery. RESULTS: 103,606 patients diagnosed with non-ocular cutaneous primary melanoma met criteria during this period. 93.3% (n = 96620) were in urban areas and 6.7% (n = 6986) were in rural areas. On multivariate regression controlling for age, sex, race, ethnicity, and stage patients living in a rural area were less likely to receive recommended surgery (aOR .52, 95% CI: .29-.90, P = .02) and had increased hazard of melanoma-specific mortality (aHR 1.19, 95% CI: 1.02-1.40, P = .03) even after additionally controlling for surgery receipt. CONCLUSION: Using a large national cohort, our study found that rural patients were less likely to receive recommended surgery and had shorter melanoma cause-specific survival. Our findings highlight the importance of access to cancer care in rural areas and how this ultimately effects survival for these patients.

Impact of Bariatric Surgery on Mortality of Mitral Valve Surgery: A National Analysis.

OBJECTIVE: Obesity is a common comorbidity of cardiac surgery patients. The goal of this study is to determine if a lower weight achieved through bariatric surgery has any association with mitral valve (MV) replacement or repair surgery mortality. METHODS: This study used a retrospective analysis of the National Inpatient Sample dataset from 2012 to 2020. Adult patients who underwent MV surgery with normal weight following bariatric surgery (n = 1,125) and patients with obesity (n = 48,555) were compared. The primary outcome was in-hospital mortality. RESULTS: This study included 49,680 patients. The median age was 64 (55 to 71) years, and the majority were female (55%). Bariatric surgery was found to significantly decrease the odds of mortality, even after adjusting for important covariates, indicating a reduction of mortality risk by 54% (adjusted odds ratio = 0.46, p = 0.024). Other significant protective factors include isolated and elective surgery. Significant risk factors were older age, female sex, and diabetes mellitus. Patients who were obese demonstrated longer lengths of stay (LOS), greater transfers to other facilities, and higher hospital costs. CONCLUSIONS: In patients receiving MV surgery, bariatric surgery demonstrated significant survival benefits during hospitalization, in addition to reducing LOS and cost. Our data support prior evidence of bariatric surgery improving cardiovascular outcomes. Therefore, bariatric surgery may be a meaningful method of weight loss to improve surgical patient outcomes in patients with obesity. However, longer-term data are needed.

Predictors of outcomes in patients with obesity following mitral valve surgery.

Objective: Few studies have assessed the outcomes of mitral valve surgery in patients with obesity. We sought to study factors that determine the in-hospital outcomes of this population to help clinicians provide optimal care. Methods: A retrospective analysis of adult patients with obesity who underwent open mitral valve replacement or repair between January 1, 2012, and December 31, 2020, was conducted using the National Inpatient Sample. Weighted logistic regression and random forest analyses were performed to assess factors associated with mortality and the interaction of each variable. Results: Of the 48,775 patients with obesity, 34% had morbid obesity (body mass index ≥40), 55% were women, 66% underwent elective surgery, and 55% received isolated open mitral valve replacement or repair. In-hospital mortality was 5.0% (n = 2430). After adjusting for important covariates, a greater risk of mortality was associated with older patients (adjusted odds ratio [aOR], 1.24; 95% CI, 1.08-1.43), higher Elixhauser comorbidity score (aOR, 2.10; 95% CI, 1.87-2.36), prior valve surgery (aOR, 1.63; 95% CI, 1.01-2.63), and more than 2 concomitant procedures (aOR, 2.83; 95% CI, 2.07-3.85). Lower mortality was associated with elective admissions (aOR, 0.70; 95% CI, 0.56-0.87) and valve repair (aOR, 0.58; 95% CI, 0.46-0.73). Machine learning identified several interactions associated with early mortality, such as Elixhauser score, female sex, body mass index ≥40, and kidney failure. Conclusions: The complexity of presentation, comorbidities in older and female patients, and morbid obesity are independently associated with an increased risk of mortality in patients undergoing open mitral valve replacement or repair. Morbid obesity and sex disparity should be recognized in this population, and physicians should consider older patients and females with multiple comorbidities for earlier and more opportune treatment windows.

United States county jail treatment and care of pregnant incarcerated persons with opioid use disorder.

BACKGROUND: Standards of care for pregnant persons with opioid use disorder (OUD) have been published across multiple institutions specializing in obstetrics and addiction medicine. Yet, this population faces serious barriers in accessing medications for OUD (MOUD) while incarcerated. Therefore, we examined the availability of MOUD in jails. METHODS: A Cross-sectional survey of jail administrators (n=371 across 42 states; 2018-2019) was conducted. Key indicators for this analysis include pregnancy testing at intake, number of county jails offering methadone or buprenorphine to pregnant incarcerated persons for detoxification on admission, continuation of pre-incarceration treatment, or linkage to post-incarceration treatment. Analyses were performed using SAS. FINDINGS: Pregnant incarcerated persons had greater access to MOUD than non-pregnant persons (χ2=142.10, p<0.0001). Larger jurisdiction size and urban jails were significantly more likely to offer MOUD (χ2=30.12, p<0.0001; χ2=26.46, p<0.0001). Methadone was the most common MOUD offered for continued care for all incarcerated persons. Of the 144 jails within a county with at least one public methadone clinic, 33% did not offer methadone treatment to pregnant persons, and over 80% did not provide linkage after release from jail. CONCLUSION: MOUD access was greater for pregnant incarcerated persons compared to non-pregnant persons. Compared to urban jails, rural jails were significantly less likely to offer MOUD, even as the number of opioid deaths in rural counties continues to surpass those in urban counties. The lack of post-incarceration linkage in counties with at least one public methadone clinic could be indicative of broader issues surrounding connections to MOUD resources.

Isolated Tricuspid Valve Repair Versus Replacement: Predictors of Mortality on the National Level.

OBJECTIVE: Isolated tricuspid valve surgery (TVR) is rarely performed, and literature reports are confined to small sample sizes and old studies. Thus, the advantage of repair over replacement could not be determined. We aimed to evaluate repair and replacement outcomes along with predictors of mortality for TVR on a national level. METHODS: All adult patients (18+ years old) who underwent TVR from 2011 to 2020 were identified using the National Inpatient Sample dataset. The primary outcome was in-hospital mortality. Secondary outcomes included complications, length of stay (LOS), hospitalization cost, and discharge disposition. RESULTS: Over a 10-year period, 37,931 patients had TVR and predominantly underwent repair (n = 25,027, 66.0%). In comparison with patients who underwent tricuspid replacement, more patients with a history of liver disease and pulmonary hypertension presented for repair surgery, and fewer patients had endocarditis and rheumatic valve disease (P < 0.001). The repair group had less mortality, less stroke, shorter LOS, and reduced cost, while the replacement group had fewer myocardial infarctions (P < 0.05). However, the outcomes were not different for cardiac arrest, wound complications, or bleeding. After excluding congenital TV disease and adjusting for relevant factors, TV repair was associated with a reduced in-hospital mortality by 28% (adjusted odds ratio [aOR] = 0.72, P = 0.011). Older age increased mortality risk by 3-fold, prior stroke by 2-fold, and liver diseases by 5-fold (P < 0.001). Patients undergoing TVR in recent years had a better chance of survival (aOR = 0.92, P < 0.001). CONCLUSIONS: TV repair has better outcomes than replacement does. Patient comorbidities and late presentation play an independently significant role in determining outcomes.

Women in mechanical circulatory support: She persisted!

Many women physicians have blazed trails and played instrumental roles in advancing the field of Advanced Heart Failure (AHF), Mechanical Circulatory Support (MCS), and cardiac transplantation to its current recognition and glory. In contrast to other areas of cardiology, women have played an integral role in the evolution and emergence of this sub-specialty. Although the ceiling had been broken much later for women cardiothoracic (CT) surgeons in the field of AHF, the ingress of women into surgical fields particularly CT surgery was stonewalled due to pervasive stereotyping. The constancy, commitment, and contributions of women to the field of AHF and MCS cannot be minimized in bringing this field to the forefront of innovation both from technological aspect as well as in redesigning of healthcare delivery models. Integrated team-based approach is a necessity for the optimal care of MCS patients and forced institutions to develop this approach when patients with durable left ventricular assist devices (LVAD) began discharging from the hospitals to local communities. Women in various roles in this field played a pivotal role in developing and designing patient centered care and coordination of care in a multidisciplinary manner. While embracing the challenges and turning them to opportunities, establishing partnerships and finding solutions with expectations to egalitarianism, women in this field continue to push boundaries and subscribe to the continued evolution of the field of AHF and advanced cardiac therapies.
