Congenital heart defects (CHDs) are complex conditions affecting the heart and/or great vessels that are present at birth. These defects occur in approximately 9 in every 1000 live births. From diagnosis to intervention, care has dramatically improved over the last several decades. Patients with CHDs are now living well into adulthood. However, there are factors that have been associated with poor outcomes across the lifespan of these patients. These factors include sociodemographic and socioeconomic positions. This commentary examined the disparities and solutions within the evolution of CHD care in the United States.
OBJECTIVE:Patients are increasingly using the internet to obtain health care information. US News and World Report Best Hospital rankings received more than 103 million views in 2021. Considering 21% of thoracic surgery patients are minorities, 27.9% are in the bottom quartile of household income, and 70% have Medicare/Medicaid or no insurance, online patient educational materials (PEMs) should be accessible and written at a level easily understood by majority of patients. We performed a comprehensive analysis of readability of websites containing patient-centered resources across all adult thoracic surgery areas.METHODS:Online PEMs on thoracic surgical procedures were collected from top 50 hospitals for pulmonology and lung surgery ranked by US News and World Report Best Hospital as of December 1, 2021. Text pertaining to thoracic surgical procedures was collected and divided into 4 procedural genres: esophageal, lung, transplant procedures, and other. Texts were analyzed using OleanderSoftware's Readability Suite through the Raygor readability test.RESULTS:Three hundred seventy-two articles met criteria for analysis. Websites were difficult to read; mean (standard deviation) readability score for all content required a 13.9 (3.6) grade level for comprehension. The mean (standard deviation) readability for esophageal, lung, lung transplant, and other surgeries were 14.5 (3.6), 13.1 (3.6), 11.5 (3.9), and 13.4 (3.7), respectively.CONCLUSIONS:Online PEMs required at least a college reading level to comprehend, well exceeding the sixth-grade level recommended by the American Medical Association. As digital health becomes increasingly relevant, improving the readability of online PEMs in adult cardiac surgery will facilitate equitable access to high-quality care.
Objective: Anterior mitral anular calcification, particularly in radiation heart disease, and previous valve replacement with destroyed intervalvular fibrosa are challenging for prosthesis sizing and placement. The Commando procedure with intervalvular fibrosa reconstruction permits double-valve replacement in these challenging conditions. We referenced outcomes after Commando procedures to standard double-valve replacements. Methods: From January 2011 to January 2022, 129 Commando procedures and 1191 aortic and mitral double-valve replacements were performed at the Cleveland Clinic, excluding endocarditis. Reasons for the Commando were severe calcification after radiation (n = 67), without radiation (n = 43), and others (n = 19). Commando procedures were referenced to a subset of double-valve replacements using balancing-score methods (109 pairs). Results: Between balanced groups, Commando versus double-valve replacement had higher total calcium scores (median 6140 vs 2680 HU, P = .03). Hospital outcomes were similar, including operative mortality (12/11% vs 8/7.3%, P = .35) and reoperation for bleeding (9/8.3% vs 5/4.6%, P = .28). Survival and freedom from reoperation at 5 years were 54% versus 67% (P = .33) and 87% versus 100% (P = .04), respectively. Higher calcium score was associated with lower survival after double-valve replacement but not after the Commando. The Commando procedure had lower aortic valve mean gradients at 4 years (9.4 vs 11 mm Hg, P = .04). After Commando procedures for calcification, 5-year survival was 60% and 59% with and without radiation, respectively (P = .47). Conclusions: The Commando procedure with reconstruction of the intervalvular fibrosa destroyed by mitral anular calcification, radiation, or previous surgery demonstrates acceptable outcomes similar to standard double-valve replacement. More experience and long-term outcomes are required to refine patient selection for and application of the Commando approach.
OBJECTIVES:To identify preoperative predictors of postcardiotomy cardiogenic shock in patients with ischemic and nonischemic cardiomyopathy and evaluate trajectory of postoperative ventricular function. METHODS:From January 2017 to January 2020, 238 patients with ejection fraction <30% (206/238) or 30% to 34% with at least moderately severe mitral regurgitation (32/238) underwent conventional cardiac surgery at Cleveland Clinic, 125 with ischemic and 113 with nonischemic cardiomyopathy. Preoperative ejection fraction was 25 ± 4.5%. The primary outcome was postcardiotomy cardiogenic shock, defined as need for microaxial temporary left ventricular assist device, extracorporeal membrane oxygenation, or vasoactive-inotropic score >25. RandomForestSRC was used to identify its predictors. RESULTS:Postcardiotomy cardiogenic shock occurred in 27% (65/238). Pulmonary artery pulsatility index <3.5 and pulmonary capillary wedge pressure >19 mm Hg were the most important factors predictive of postcardiotomy cardiogenic shock in ischemic cardiomyopathy. Cardiac index <2.2 L·min-1 m-2 and pulmonary capillary wedge pressure >21 mm Hg were the most important predictive factors in nonischemic cardiomyopathy. Operative mortality was 1.7%. Ejection fraction at 12 months after surgery increased to 39% (confidence interval, 35-40%) in the ischemic group and 37% (confidence interval, 35-38%) in the nonischemic cardiomyopathy group. CONCLUSIONS:Predictors of postcardiotomy cardiogenic shock were different in ischemic and nonischemic cardiomyopathy. Right heart dysfunction, indicated by low pulmonary artery pulsatility index, was the most important predictor in ischemic cardiomyopathy, whereas greater degree of cardiac decompensation was the most important in nonischemic cardiomyopathy. Therefore, preoperative right heart catheterization will help identify patients with low ejection fraction who are at greater risk of postcardiotomy cardiogenic shock.
In this issue of Seminars in Thoracic and Cardiovascular Surgery, Aranda-Michel and colleagues evaluated the change in cardiothoracic surgery residency application towards a more holistic approach. This is a shift away from traditional numerical metrics such as USMLE scores to research, sub-internships and away rotations, interviews, and letters of recommendation (LOR). 1 Aranda-Michel E.

Objective: To maximize successful repair of bicuspid aortic valves by adding figure- of-8 hitch -up stitches at commissures. Methods: From 2000 to 2022, bicuspid aortic valve repair was performed on 1112 patients at Cleveland Clinic, with 367 patients receiving figure -of -8 hitch -up stitches along with classical techniques, including Cabrol suture, cusp plication, raphe resection, and valve -sparing root replacement. Operative outcomes, repair durability, and survival were assessed in the figure -of -8 hitch -up stitches cohort, and outcomes were compared among 195 balancing -score -matched patient pairs who underwent bicuspid aortic valve repair with and without figure -of -8 hitch -up stitches. Results: Patients who underwent bicuspid aortic valve repair with figure -of -8 stitches had an operative mortality of 0.3 % (1 of 367) and in -hospital reoperation for aortic valve dysfunction of 1.1 % (4 of 367). At 10 years, prevalence of severe aortic regurgitation was 8.6 % , mean gradient 24 mm Hg, freedom from aortic valve reoperation 75 % , and survival 98 % . In matched cohorts, operative mortality was similar (0.51 % vs 0 % ; P > .9) as were morbidities, including in -hospital reoperation due to aortic valve dysfunction (1.0 % vs 1.5 % ; P > .9). Comparable long-term outcomes were observed at 10 years (prevalence of severe aortic regurgitation of 8.7 % vs 5.0 % [ P = .11], mean gradient 18 vs 17 mm Hg [ P = .40]; freedom from aortic valve reoperation 80 % vs 81 % [ P = .73]; and survival 99.5 % vs 94.6 % [ P = .18]). Conclusions: Figure -of -8 hitch -up stitch is a safe bicuspid aortic valve repair technique. It increases the likelihood of a successful repair without increasing risk of cusp tear and achieves satisfactory long-term survival and durability when added to classical repair techniques.

BACKGROUND In 2007, congenital cardiac surgery became a recognized fellowship by the American Council of Graduate Medical Education (ACGME). Beginning in 2023, the fellowship transitioned from a 1-year to a 2-year program. Our objective is to provide current benchmarks by surveying current training programs and assessing characteristics contributing to career success. METHODS This was a survey-based study in which tailored questionnaires were distributed to program directors (PDs) and graduates of the ACGME accredited training programs. Data collection included responses to multiple-choice and open-ended questions relevant to didactics, operative training, training center characteristics, mentorship, and employment characteristics. Results were analyzed using summary statistics and subgroup and multivariable analyses. RESULTS The survey yielded responses from 13 of 15 PDs (86%) and 41 of 101 graduates (41%) from ACGME accredited programs. Perceptions among PDs and graduates were somewhat discordant, with PDs more optimistic than graduates. Of PDs, 77% (n = 10) believed current training adequately prepares fellows and is successful in securing employment for graduates. The responses from graduates demonstrated 30% (n = 12) were dissatisfied with operative experience and 24% (n = 10) with overall training. Being supported during the first 5 years of practice was significantly associated with retention in congenital cardiac surgery and greater practicing case volumes. CONCLUSIONS Dichotomous views exist between graduates and PDs regarding success in training. Mentorship during the early career was associated with increased case volumes, career satisfaction, and retention in the congenital cardiac surgery field. Educational bodies should incorporate these elements during training and after graduation.

Objective: Intravascular ultrasound (IVUS) use in lower extremity interventions is growing in popularity owing to its imaging in the axial plane, superior detail in imaging lesion characteristics, and its enhanced ability to delineate lesion severity and extent compared with catheter angiograms. However, there are conflicting data regarding whether IVUS affects outcomes. The purpose of this study was to assess the effect associated with IVUS implementation in femoropopliteal interventions. Methods: This retrospective cohort study used Vascular Quality Initiative data. Patients undergoing an index endovascular femoropopliteal revascularization from 2016 to 2021 were included. Patients were differentiated by whether or not IVUS was used to assess the femoropopliteal segment during intervention (no IVUS, IVUS). Propensity score matching, based on preoperative demographics and measures of disease severity was used. Primary outcomes were major amputation-free survival (AFS), femoropopliteal reintervention-free survival (RFS), and primarily patent survival (PPS) at 12 months. Results: IVUS use grew steadily throughout the study period, comprising 0.6% of interventions in 2016 and increasing to 8.2% of interventions by 2021; growth was most dramatic in ambulatory surgical center or office-based laboratory settings where IVUS use grew from 4.4% to 43% to 47% of interventions. In unmatched cohorts, patients receiving interventions using IVUS tended to have lower prevalence of multiple cardiovascular comorbidities (eg, congestive heart failure, hypertension, diabetes, and dialysis dependence) and presented more often with claudication and less often with chronic limb-threatening ischemia (CLTI). Intraoperatively, IVUS was used more often in complex femoropopliteal lesions (Transatlantic Intersociety grade D vs A), and more often in conjunction with stenting and/or atherectomy. IVUS use was associated with improved AFS, but similar RFS and PPS at 12 months. However, in multivariable analysis IVUS was not associated with any of the primary outcomes independently; rather, all outcomes were influenced primarily by CLTI, dialysis dependence, and prior major amputation status; technical outcomes (ie, RFS and PPS loss) were further driven by complexity of lesion (worse in Transatlantic Intersociety grade D vs A lesions) and treatment setting (ie, ambulatory surgical center or office-based laboratory setting associated with increased hazard for RFS and PPS loss). Conclusions: IVUS implementation in femoropopliteal interventions is growing, with rapid adoption among interventions in ambulatory surgical centers and office-based laboratories. IVUS was not associated with an effect on technical outcomes at 12 months; improvement in major AFS was observed; however, multivariable analysis suggests this finding may be an effect of confounding by multiple factors highly associated with IVUS use, namely, in patients with lower prevalence of CLTI, dialysis dependence, and prior major amputations, thus conveying baseline lower risk for major amputation and death.

Introduction: Patients are increasingly using the Internet to obtain healthcare information. Considering 21% of cardiac surgery patients are minorities, 27.9% are in the bottom quartile of household income, and 70% have Medicare/Medicaid or no insurance, online patient educational materials (PEMs) should be accessible and written at a level easily understood by majority of patients. We performed a comprehensive analysis of readability of websites containing patient-centered resources across all adult cardiac surgery areas. Hypothesis: Methods: Online PEMs on cardiac surgical procedures (CSP) were collected from top 50 hospitals for cardiology and heart surgery ranked by US News and World Report as of December 1st, 2021. Text pertaining to CSPs was collected and divided into five procedural genres: mitral valve, coronary artery bypass, heart transplant, aortic valve, and aortic surgeries. Texts were analyzed using OleanderSoftware’s Readability Suite through the Raygor readability test. Results: N=282 articles met criteria for analysis. Online content for all 5 surgical genres were difficult to read, with mean (SD) grade level readability score for all content at 13.8 (3.1, panel a). The mean (SD) readability for mitral valve, coronary artery bypass, heart transplant, aortic valve, and aortic surgeries were 14.4 (3.0, panel b), 13.9 (3.3, panel c), 12.2 (2.7, panel d), 13.5 (3.1, panel e), and 14.3 (2.8, panel f) respectively. Online resources for content within the 5 genres required at least college reading level for comprehension. Conclusions: Online PEMs exceeded the sixth-grade level recommended by the American Medical Association and the second-grade level previous established at our institution in all included genres of adult cardiac surgery. Improving the readability of online PEMs in adult cardiac surgery will facilitate equitable access to high-quality care.

In this study, we first sought tosummarize the current public search patterns for vasectomy reversal information. Next, we studied internet advertising information provided by vasectomy reversal clinic websites to better understand the training patterns, geographical distribution, technical details, reported success rates, and cost for providers in the United States. METHODS: Google trends was used to identify search trends over the preceding 10 years. Web search engines were queried using the term “+(vasectomy reversal OR vasovasostomy OR vasoepididymostomy) +[state]” and assessed by clinicians for inclusion and relevance. RESULTS: First, vasectomy reversal searches represented 6% of the searches for vasectomy during the same interval. There was no strong trend in search frequency or seasonal variation over the 10-year search period. Oklahoma and Wyoming showed the highest enrichment for vasectomy reversal searches relative to population.Next, A total of 251 unique clinics were identified. Providers were 98% male and graduated from residencies in urology (97%), obgyn (1%), general surgery, 1%), orthopedics (1%), and family medicine (1%). 44% of urologists had completed fellowship training in andrology. 10% of providers explicitly did not perform vasoepididymostomy even if indicated. 42% of websites reported success rates, which varied from 77% to 100%, and there was no relationship between success and cost. 17% of websites reported total cost ranging from $1990 to $14175 (median $6318). The highest density of reversal providers per million patients occurred in the Northeast (1.63) and the lowest density was in the west (1.04). There was no statistical difference in cost by region. CONCLUSIONS: Vasectomy reversals are performed using a variety of techniques by surgeons with a wide breadth and depth of training. Costs vary by an order of magnitude, and reported success rates vary significantly. Only a minority of clinic websites discuss complications, and not all providers offer vasoepididymostomy when indicated. This information underscores the difficulty that patients may face when choosing their surgeon and suggests efforts towards standardization and transparency may be of benefit to the public.
