Long-Term Outcomes and Characteristics Associated With Mortality of Adult Patients Post Fontan Surgery: 27-Year Single-Center Experience.

Data on the characteristics and long-term outcomes of patients who underwent Fontan surgery and surviving into adulthood are limited. We aimed to describe our center's long-term experience with this unique patient population. Included were adult patients who had undergone Fontan surgery and were followed up at our Adult Congenital Heart Disease clinic between the years 1994 and 2021. We describe cardiac and noncardiac morbidities, medical treatment, laboratory data, echocardiographic characteristics, and all-cause mortality. The primary outcome was a composite of heart failure hospitalizations or death. A total of 107 patients who underwent Fontan surgery were followed up during the study period; 46.7% were male. The mean age at time of Fontan was 7.4 ± 6.2 years and the mean age at the last follow-up or at the time of an outcome event was 35.0 ± 8.0 years (range 21.1 to 62.8). At the last documented follow-up, 74.7% of the cohort were in New York Heart Association functional class I/II. The common morbidities included atrial arrythmias (37%) and stroke (17%). The primary outcome occurred in 17.7%. By the end of the study period, 9.3% of the patients in the cohort died. In a multivariate logistic regression analysis, controlling for gender, age, and Fontan type, worse functional class at the last follow-up (New York Heart Association III/IV vs I/II) was significantly associated with the risk of the primary outcome (odds ratio 34.57, 95% confidence interval 6.728 to 177.623, p <0.001). In conclusion, long-term outcomes of patients surviving into adulthood with a Fontan circulation is encouraging. Most of these patients achieve good functional cardiovascular status, despite the complex anatomy and a substantial burden of co-morbid conditions, specifically, atrial arrythmias and thrombotic events. Functional class was independently associated with heart failure hospitalizations and mortality.

Hemoglobin decline as a signal for hyperprolactinemia onset prior to prolactinoma diagnosis in hypogonadal men.

BACKGROUND: Men harboring prolactinomas frequently suffer from central hypogonadism with secondary anemia. They present insidious and nonspecific symptoms of hypogonadism, making it difficult to diagnose the disease and determine its duration. The result is a delay in diagnosis, which may have harmful hormonal and metabolic consequences. We hypothesized that a decrease in hemoglobin (HB) levels prior to prolactinoma diagnosis, may signal hyperprolactinemia onset and estimate disease duration. METHODS: We retrospectively evaluated the prediagnosis temporal trends in HB levels of 70 males with prolactinoma, diagnosed from January 2010 to July 2022. Men without hypogonadism, patients that received testosterone, and those with unrelated anemia were excluded. RESULTS: Sixty-one of seventy men (87%) with prolactinoma presented with hypogonadism, and forty men (57%) had HB levels ≤13.5 g/dL at diagnosis. We identified 25 patients with "informative" HB curves (mean age, 46.1±14.9 years; median prolactin, 952 ng/mL; median follow-up, 14.0 years), demonstrating an obvious prediagnosis HB decrease (greater than 1.0 g/dL), from a prediagnosis baseline HB of 14.4 ± 0.3 to 12.9 ± 0.5 g/dL at diagnosis. The median "low-HB duration" (from the first low HB measurement to hyperprolactinemia diagnosis) was 6.1 years (IQR, 3.3-8.8 years). In symptomatic patients, we identified a correlation between "low-HB duration" and patient-reported sexual dysfunction duration (n = 17, R = 0.502, p = 0.04). The "low-HB duration" was significantly longer than the reported sexual dysfunction duration (7.0 ± 4.5 vs. 2.9 ± 2.5 years, p = 0.01). CONCLUSIONS: In our cohort of men with prolactinomas and hypogonadism, we found a marked decrease in HB levels that preceded prolactinoma diagnosis by a median of 6.1 years, with a mean delay of 4.1 years between HB decrease and hypogonadal symptoms appearance. These results suggest that HB decline prior to prolactinoma diagnosis may serve as a marker for hyperprolactinemia onset in a subset of hypogonadal men and allow a more accurate assessment of disease duration.

Outcomes of Redo Transcatheter Aortic Valve Replacement According to the Initial and Subsequent Valve Type.

BACKGROUND: As transcatheter aortic valve (TAV) replacement is increasingly used in patients with longer life expectancy, a sizable proportion will require redo TAV replacement (TAVR). The unique configuration of balloon-expandable TAV (bTAV) vs a self-expanding TAV (sTAV) potentially affects TAV-in-TAV outcome. OBJECTIVES: The purpose of this study was to better inform prosthesis selection, TAV-in-TAV outcomes were assessed according to the type of initial and subsequent TAV. METHODS: Patients from the Redo-TAVR registry were analyzed using propensity weighting according to their initial valve type (bTAV [n = 115] vs sTAV [n = 106]) and subsequent valve type (bTAV [n = 130] vs sTAV [n = 91]). RESULTS: Patients with failed bTAVs presented later (vs sTAV) (4.9 ± 2.1 years vs 3.7 ± 2.3 years; P < 0.001), with smaller effective orifice area (1.0 ± 0.7 cm2 vs 1.3 ± 0.8 cm2; P = 0.018) and less frequent dominant regurgitation (16.2% vs 47.3%; P < 0.001). Mortality at 30 days was 2.3% (TAV-in-bTAV) vs 0% (TAV-in-sTAV) (P = 0.499) and 1.7% (bTAV-in-TAV) vs 1.0% (sTAV-in-TAV) (P = 0.612); procedural safety was 72.6% (TAV-in-bTAV) vs 71.2% (TAV-in-sTAV) (P = 0.817) and 73.2% (bTAV-in-TAV) vs 76.5% (sTAV-in-TAV) (P = 0.590). Device success was similar according to initial valve type but higher with subsequent sTAV vs bTAV (77.2% vs 64.3%; P = 0.045), primarily because of lower residual gradients (10.3 mm Hg [8.9-11.7 mm Hg] vs 15.2 mm Hg [13.2-17.1 mm Hg]; P < 0.001). Residual regurgitation (moderate or greater) was similar after bTAV-in-TAV and sTAV-in-TAV (5.7%) and nominally higher after TAV-in-bTAV (9.1%) vs TAV-in-sTAV (4.4%) (P = 0.176). CONCLUSIONS: In selected patients, no association was observed between TAV type and redo TAVR safety or mortality, yet subsequent sTAV was associated with higher device success because of lower redo gradients. These findings are preliminary, and more data are needed to guide valve choice for redo TAVR.

Self-Reported Mental and Physical Measures in Adult Fontan Patients.

Introduction: The Fontan procedure is a palliative operation for patients with single functional ventricles, arising from a heterogeneous group of heart defects. There is a considerable gap in evidence regarding the self-reported physical and mental health of these patients surviving to adulthood. Methods and Results: We administered the PROMIS® Global Short Form (v 1.2) to Fontan patients during their scheduled clinic visits during 2017−2018. The raw PROMIS scores were subsequently converted to standardized T-scores, where the mean performance was 50 for the general population. We used Cronbach's alpha to assess reliability, with >0.8 considered good. A total of 42 patients were included. The median age was 30 (IQR: 24−34) years and 59% (95% CI: 43−74%) were female. The median time from birth to operation was 4.5 (IQR: 3−8) years, with 55% having an extracardiac Fontan. The questionnaire had good internal reliability with an alpha of 0.87. Seventy-one percent of respondents rated their overall health as "excellent" or "good". The mean T-score for physical health was 46.6, lower than the age-group mean (51.6, p < 0.001). The mean T-score for mental health was 53.3, higher than the age-group mean (48.5, p < 0.001). T-scores showed strong correlation with each other (r = 0.7) and weak correlation with age and time from procedure. There was no association of T-score with diagnosis or operation type. Conclusions: Adult Fontan patients report better mental health despite worse reporting physical health compared with the age group means. Patient-reported measures can provide clinically meaningful insights about the care of patients with complex congenital heart disease.

Center Valve Preference and Outcomes of Transcatheter Aortic Valve Replacement: Insights From the AMTRAC Registry.

BACKGROUND: Data on outcomes of transcatheter aortic valve replacement (TAVR) using balloon-expandable valves (BEVs) or self-expandable valves (SEVs) as well as the impact of center valve preference on these outcomes are limited. OBJECTIVES: The aim of this study was to compare outcomes of TAVR procedures using third-generation BEVs and SEVs stratified by center valve preference. METHODS: In a multicenter registry (n = 17), 13 centers exhibited valve preference (66.6%-90% of volume) and were included. Outcomes were compared between BEVs and SEVs stratified by center valve preference. RESULTS: In total, 7,528 TAVR procedures (3,854 with SEVs and 3,674 with BEVs) were included. The mean age was 81 years, and the mean Society of Thoracic Surgeons score was 5.2. Baseline characteristics were similar between BEVs and SEVs. Need for pacemaker implantation was higher with SEVs at BEV- and SEV-dominant centers (17.8% vs 9.3% [P < 0.001] and 12.7% vs 10.0% [P = 0.036], respectively; HR: 1.51; P for interaction = 0.021), risk for cerebrovascular accident was higher with SEVs at BEV-dominant but not SEV-dominant centers (3.6% vs 1.1% [P < 0.001] and 2.2% vs 1.4% [P = 0.162]; HR: 2.08; P for interaction < 0.01). Aortic regurgitation greater than mild was more frequent with SEVs at BEV-dominant centers and similar with BEVs regardless of center dominance (5.2% vs 2.8% [P < 0.001] and 3.4% vs 3.7% [P = 0.504], respectively). Two-year mortality was higher with SEVs at BEV-dominant centers but not at SEV-dominant centers (21.9% vs 16.9% [P = 0.021] and 16.8% vs 16.5% [P = 0.642], respectively; HR: 1.20; P for interaction = 0.032). CONCLUSIONS: Periprocedural outcomes, aortic regurgitation greater than mild, and 2-year mortality are worse when TAVR is performed using SEVs at BEV-dominant centers. Outcomes are similar regardless of valve type at SEV-dominant centers. The present results stress the need to account for this factor when comparing BEV and SEV outcomes.

Temporal Trends in the Characteristics, Treatment, and Outcomes of Conservatively Managed Patients With Non-ST Elevation Acute Coronary Syndrome (from the ACSIS Registry 2000 to 2016).

Despite advances in percutaneous coronary interventions (PCI), a subgroup of acute coronary syndrome (ACS) patients are still managed medically by a conservative approach. We sought to characterize a contemporary, large-scale, real-world cohort of ACS patients treated conservatively via pharmacological management, without PCI. Data was gathered from the ACS Israeli Survey (ACSIS) between 2000 and 2016, encompassing all consecutive patients admitted to cardiology wards with an ACS diagnosis. Included were 3,543 conservatively managed patients with non-ST elevation ACS (NSTE-ACS). Patients with ST elevation MI or those who underwent any coronary revascularization (PCI or bypass surgery) were excluded. Primary endpoints were 30-day major adverse cardiovascular events (MACE) and 1-year mortality. The study cohort was divided to 4 time-periods. Over 2 decades, medically managed NSTE-ACS patients remained of similar age (67 ± 13 years, p = 0.78), but had more atherosclerotic risk-factors and comorbidities. During time, patients were more often referred to diagnostic angiography and treated with statins, ACE-I/ARBs, and P2Y12 inhibitors (p < 0.001 for each). Over time, there were less in-hospital complications such as kidney injury and heart failure. The rate of 30-day MACE decreased (from 20.7% to 10.3%, earliest to latest period, p < 0.001). Compared with the earliest period, the latest period was associated with a reduction in 1-year mortality (14.7% to 11.6%; adjusted HR 0.65, 95% CI 0.47 to 0.90). In conclusion, Over 2 decades, in medically managed NSTE-ACS patients, short term prognosis has significantly improved while 1-year mortality demonstrated improvement only recently, likely due to incremental benefits of medical management.

Myocarditis after Covid-19 Vaccination in a Large Health Care Organization.

BACKGROUND: Reports have suggested an association between the development of myocarditis and the receipt of messenger RNA (mRNA) vaccines against coronavirus disease 2019 (Covid-19), but the frequency and severity of myocarditis after vaccination have not been extensively explored. METHODS: We searched the database of Clalit Health Services, the largest health care organization (HCO) in Israel, for diagnoses of myocarditis in patients who had received at least one dose of the BNT162b2 mRNA vaccine (Pfizer-BioNTech). The diagnosis of myocarditis was adjudicated by cardiologists using the case definition used by the Centers for Disease Control and Prevention. We abstracted the presentation, clinical course, and outcome from the patient's electronic health record. We performed a Kaplan-Meier analysis of the incidence of myocarditis up to 42 days after the first vaccine dose. RESULTS: Among more than 2.5 million vaccinated HCO members who were 16 years of age or older, 54 cases met the criteria for myocarditis. The estimated incidence per 100,000 persons who had received at least one dose of vaccine was 2.13 cases (95% confidence interval [CI], 1.56 to 2.70). The highest incidence of myocarditis (10.69 cases per 100,000 persons; 95% CI, 6.93 to 14.46) was reported in male patients between the ages of 16 and 29 years. A total of 76% of cases of myocarditis were described as mild and 22% as intermediate; 1 case was associated with cardiogenic shock. After a median follow-up of 83 days after the onset of myocarditis, 1 patient had been readmitted to the hospital, and 1 had died of an unknown cause after discharge. Of 14 patients who had left ventricular dysfunction on echocardiography during admission, 10 still had such dysfunction at the time of hospital discharge. Of these patients, 5 underwent subsequent testing that revealed normal heart function. CONCLUSIONS: Among patients in a large Israeli health care system who had received at least one dose of the BNT162b2 mRNA vaccine, the estimated incidence of myocarditis was 2.13 cases per 100,000 persons; the highest incidence was among male patients between the ages of 16 and 29 years. Most cases of myocarditis were mild or moderate in severity.
