Development of a Novel Adult Congenital Heart Disease-Specific Patient-Reported Outcome Metric

Background Patient-reported outcome metrics (PROs) quantify important outcomes in clinical trials and can be sensitive measures of patient experience in clinical practice. Currently, there is no validated disease-specific PRO for adults with congenital heart disease (ACHD). Methods and Results We conducted a preliminary psychometric validation of a novel ACHD PRO. ACHD patients were recruited prospectively from 2 institutions and completed a series of questionnaires, a physician health assessment, and a 6-minute walk test. Participants returned to complete the same questionnaires and assessment 3 months±2 weeks later. We tested the internal consistency and test-retest reliability by comparing responses among clinically stable patients at the 2 study visits. We assessed convergent and divergent validity by comparison of ACHD PRO responses to existing validated questionnaires. We assessed responsiveness by comparison with patient-reported clinical change. One hundred three patients completed 1 study visit and 81 completed both. The ACHD PRO demonstrated good internal consistency in each of its 5 domains (Cronbach's α: 0.87; 0.74; 0.74; 0.90; and 0.89, respectively) and in the overall summary score (0.92). Test-retest reliability was good with an intraclass correlation ≥0.73 for all domains and 0.78 for the Summary Score. The ACHD PRO accurately assessed domain concepts based on comparison with validated standards. Preliminary estimates of responsiveness suggest sensitivity to clinical status. Conclusions These studies provide initial support for the validity and reliability of the ACHD PRO. Further studies are needed to assess its sensitivity to changes in clinical status.

The Alopecia Areata Investigator Global Assessment scale: a measure for evaluating clinically meaningful success in clinical trials

BACKGROUND

Content-valid and clinically meaningful instruments are required to evaluate outcomes of therapeutic interventions in alopecia areata (AA).

OBJECTIVES

To develop an Investigator's Global Assessment (IGA) to interpret treatment response in AA treatment studies.

METHODS

Qualitative interviews were conducted in the USA with expert dermatologists and with patients with AA who had experienced ≥ 50% scalp-hair loss. Thematic data analysis identified critical outcomes and evaluated the content validity of the new IGA.

RESULTS

Expert clinicians (n = 10) judged AA treatment success by the amount of scalp-hair growth (median 80% scalp hair). Adult (n = 25) and adolescent (n = 5) patients participated. Scalp-hair loss was the most bothersome AA sign/symptom for most patients. Perceived treatment success - short of 100% scalp hair - was the presence of ~ 70-90% scalp hair (median 80%). Using additional clinician and patient insights, the Alopecia Areata Investigator Global Assessment (AA-IGA™) was developed. This clinician-reported outcome assessment is an ordinal, static measure comprising five severity categories of scalp-hair loss. Nearly all clinicians and patients in this study agreed that, for patients with ≥ 50% scalp-hair loss, successful treatment would be hair regrowth resulting in ≤ 20% scalp-hair loss.

CONCLUSIONS

We recommend using the Severity of Alopecia Tool to assess the extent (0-100%) of scalp-hair loss. The AA-IGA is a robust ordinal measure providing distinct and clinically meaningful gradations of scalp-hair loss that reflects patients' and expert clinicians' perspectives and treatment expectations. What is already known about this topic? The Severity of Alopecia Tool is widely used to assess the extent of scalp-hair loss in patients with alopecia areata. Guidelines define treatment success as a 50% improvement in scalp hair, and clinical trials have used dynamic thresholds of 50% and 90%. However, there is no clinical consensus on these endpoints, and patient perspectives on treatment success are unknown. What does this study add? Through qualitative interviews with 10 expert dermatologists and 30 patients with alopecia areata who had experienced ≥ 50% scalp-hair loss, we developed the Alopecia Areata Investigator Global Assessment (AA-IGA™) to measure five clinically meaningful gradations of alopecia areata scalp-hair loss that reflects patients' and clinicians' perspectives and expectations of treatment success in alopecia areata treatment studies. What are the clinical implications of this work? The AA-IGA is a robust ordinal measure that can inform clinical evaluation of alopecia areata treatment outcomes. The AA-IGA can be used to determine clinically meaningful treatment success for alopecia areata, with success defined by patients and clinicians as reaching ≤ 20% scalp-hair loss.

Differential impact of physical activity type on depression in adults with congenital heart disease: A multi-center international study

OBJECTIVE

This study aimed to examine the association between physical activity (PA) and depression in a large international cohort of adults with congenital heart disease (ACHD) as data about the differential impact of PA type on depression in this population are lacking.

METHODS

In 2018, we conducted a cross-sectional assessment of 3908 ACHD recruited from 24 ACHD-specialized centers in 15 countries between April 2013 to March 2015. The Hospital Anxiety and Depression Scale was used to assess self-reported depressive symptoms and the Health-Behavior Scale-Congenital Heart Disease was used to collect PA information. Cochran-Armitage tests were performed to assess trends between depressive symptom levels and PA participation. Chi-Square and Wilcoxon Rank Sum tests were utilized to examine relations between depressive symptom levels and patient characteristics. Stepwise multivariable models were then constructed to understand the independent impact of PA on depressive symptoms.

RESULTS

The overall prevalence of elevated depressive symptoms in this sample was 12% with significant differences in rates between countries (p < .001). Physically active individuals were less likely to be depressed than those who were sedentary. Of the 2 PA domains examined, sport participation rather than active commute was significantly associated with reduced symptoms of depression. After adjustment in multivariable analysis, sport participation was still significantly associated with 38% decreased probability of depressive symptoms (p < .001).

CONCLUSIONS

Sport participation is independently associated with reduced depressive symptoms. The development and promotion of sport-related exercise prescriptions uniquely designed for ACHD may improve depression status in this unique population.

Association between psychological resilience and subjective well-being in older adults living with chronic illness

We aimed to determine the impact of resilience on well-being in chronically ill adults, hypothesizing that resilient participants would have higher quality of life, life satisfaction, and happiness and less psychological distress than those with low resilience. Patients who received treatment for a chronic illness at Baylor Scott & White Health and self-identified an informal caregiver (nonpaid friend/family member who provides regular care) were eligible. After the Center for Community Research and Development administered a phone survey from March to June 2017, we built linear and ordinal logistic regression models to assess the effect of resilience on well-being while adjusting for health, finances, marital status, and gender. Forty-one participants completed the study. The average age was 67 ± 10 years; the most common illness was heart failure (39%). Participants had high resilience (median 4 [quartile 1 = 3, quartile 3 = 5], scale: 1-5), low psychological distress (4 [2, 7], scale: 0-24), high quality of life (8 [5, 9], scale: 0-10) and life satisfaction (5 ± 2, scale: 1-7), and 81% were pretty/very happy. The effect of resilience was significant in the expected directions in unadjusted analyses. After accounting for demographic, social, and clinical factors, resilience remained highly significant for psychological distress and happiness (b = -1.91, P = 0.002; odds ratio = 4.71, P = 0.003, respectively). Psychological resilience may be a resource to preserve well-being for chronically ill individuals.

Physical Activity-Related Drivers of Perceived Health Status in Adults With Congenital Heart Disease

Data on the differential impact of physical activity on perceived health status (PHS) in a large adult congenital heart disease (ACHD) patient population are lacking. We conducted a cross-sectional assessment of 4,028 ACHD patients recruited from 24 ACHD-specialized centers in 15 countries across 5 continents to examine the association between physical activity and PHS in a large international cohort of ACHD patients. A linear analog scale of the EuroQol-5D 3 level version and the 12-item Short Form Health Survey-version 2 were used to assess self-reported health status and the Health-Behavior Scale-Congenital Heart Disease was used as a subjective measurement of physical activity type, participation, and level. Correlation analyses and Wilcoxon Rank Sum tests examined bivariate relations between sample characteristics and PHS scores. Then, multivariable models were constructed to understand the impact of physical activity on PHS. Only 30% of our sample achieved recommended physical activity levels. Physically active patients reported better PHS than sedentary patients; however, the amount of physical activity was not associated with PHS. Further statistical analyses demonstrated that specifically sport participation regardless of physical activity level was a predictor of PHS. In conclusion, the majority of ACHD patients across the world are physically inactive. Sport participation appears to be the primary physical activity-related driver of PHS. By promoting sport-related exercise ACHD specialists thus may improve PHS in ACHD patients.

Contributors to disease-specific health knowledge in adults with congenital heart disease: A correlational study

OBJECTIVE

Growth in the adults with congenital heart disease (ACHD) population represents a challenge to the health care infrastructure. As patients with chronic disease are increasingly held accountable for their own care, contributors to disease-specific health knowledge, which are known to correlate with patients' participation in care, merit investigation to design patient-focused interventions.

DESIGN

We conducted a single-site, cross-sectional study of ACHD patients. Investigators retrospectively gathered clinical data as well as psychometric and health status assessments completed at the time of enrollment.

OUTCOME MEASURES

We investigated the impact of clinical and psychological variables on Leuven Knowledge Questionnaire for Congenital Heart Diseases health knowledge composite scores (HKCS). Variables with significant associations were considered in a stepwise multivariable regression model to determine which combination of variables jointly explained variability in HKCS.

RESULTS

Overall HKCS was associated with the number of prior cardiac surgeries (r = 0.273; 95% CI: 0.050-0.467; P = .016), perceived stress (r = 0.260; 95% CI: 0.033-0.458; P = .024), SF-36 emotional well-being (r = -0.251; 95% CI: -0.451, -0.024; P = .030), history of noncardiac surgery (P = .037), cirrhosis (P = .048), and presence of implantable cardioverter-defibrillator (P = .028). On multivariable modeling, only the number of cardiac surgeries was found to correlate with HKCS.

CONCLUSIONS

While univariate correlations were found between HCKS and several other clinical and psychological variables, only number of prior cardiac surgeries independently correlated with disease-specific health knowledge in ACHD patients. These results suggest that clinical and psychological variables are not impediments to disease-specific health knowledge.

Analysis of electrocardiographic intervals before and after transcatheter aortic valve implantation to predict the need for permanent pacing

Transcatheter aortic valve implantation (TAVI) is growing in utilization in the USA, and atrioventricular heart block is a common complication of the procedure. In patients with conduction system changes following TAVI, there are no clear guidelines for permanent pacing, leading to difficult clinical decisions on how long to leave temporary transvenous pacemakers in place. The aim of our study was to determine whether changes in electrocardiogram characteristics could predict the need for permanent pacing. A retrospective analysis was conducted of 209 consecutive TAVI patients seen from January 2012 to December 2015 at Baylor Heart and Vascular Hospital, Dallas. The baseline characteristics were similar between those who received a permanent pacemaker (PPM) within 7 days of the procedure (21.1%) and those who did not (78.9%); of those who did receive a PPM, 79.5% were implanted for complete heart block. The median (range) percentage change in the sum of QRS and PR was significantly higher in those who received a PPM (20.2%) than those who did not (7.1%) (P = 0.004). Using the percentage change in the sum of QRS and PR to predict PPM, the area under the curve was found to be 0.69. The optimal cutpoint was found to be 18.9% (sensitivity = 0.63, specificity = 0.73). Our study suggests that delay in the conduction system immediately following TAVI predicts the need for permanent pacing.

Clinical and Psychological Drivers of Perceived Health Status in Adults With Congenital Heart Disease

The factors having the greatest impact on self-reported health status in adults with congenital heart disease (ACHD) remain incompletely studied. We conducted a single-site, cross-sectional study of ACHD patients followed at the Center for ACHD at Washington University School of Medicine, including retrospectively gathered clinical data and psychometric and health status assessments completed at the time of enrollment. To identify primary drivers of perceived health status, we investigated the impact of the demographic, clinical, and psychological variables on self-reported health status as assessed using the Rand 36-Item Short Form Health Survey. Variables with significant associations within each domain were considered jointly in multivariable models constructed via stepwise selection. There was domain-specific heterogeneity in the variables having the greatest effect on self-reported health status. Depression was responsible for the greatest amount of variability in health status in all domains except physical functioning. In the physical functioning domain, depression remained responsible for 5% of total variability, the third most significant variable in the model. In every domain, depression more strongly influenced health status than did any cardiac-specific variable. In conclusion, depression was responsible for a significant amount of heterogeneity in all domains of self-perceived health status. Psychological variables were better predictors of health status than clinical variables.

CT differentiation of tuberculous and non-tuberculous pleural infection, with emphasis on pulmonary changes

OBJECTIVE

To determine whether pulmonary changes on computed tomography (CT) are helpful in differentiating between pleural tuberculosis (TB) and non-tuberculous pleural infection

MATERIALS AND METHODS

We retrospectively reviewed CT scans of patients with pleural tuberculous and non-tuberculous empyema, focusing on pulmonary changes such as consolidation, ground glass opacity, interlobular septal thickening, cavitation, abscess and presence and distribution of micronodules. We also assessed the presence of loss of overlying pleural integrity, peripheral bronchopleural fistula and lymphadenopathy.

RESULTS

We evaluated 65 patients with pleural TB and 43 with empyema. CT findings of pleural TB differed significantly from those of empyema with interlobular septal thickening (P = 0.022) and micronodules with subpleural, peribronchovascular and septal distribution (P < 0.001). Subpleural abscess was more frequently seen in empyema, accompanying loss of overlying pleural integrity and peripheral bronchopleural fistula (P < 0.001), but there was no statistical difference between the two groups in prevalence of consolidation, ground glass opacity, cavitation, centrilobular nodules or lymphadenopathy.

CONCLUSION

Interlobular septal thickening and micronodules with perilymphatic distribution are characteristic CT findings of pleural TB but not empyema. Presence of subpleural abscess and loss of pleural integrity or peripheral bronchopleural fistula are highly suggestive of empyema.

Comparison of Characteristics of Patients Undergoing Heart Transplantation at the Same Hospital in Two Different Time Periods (1997-2012 and 2013-2015)

Heart transplantation (HT) increases at some centers each year and decreases at others. We examined characteristics of patients having HT at the same hospital in 2 different time periods (1997-2012 and 2013-2015) by 2 different surgical groups. We compared certain clinical and morphological finding in 291 patients having HT 1997 to 2012 to finding in 228 other patients having HT from 2013 to 2015. Several significant (p <0.05) differences were found: in the most recent time period (2013-2015) compared to the earlier time period (1997-2012), the mean ages of the men were older (57 years -vs- 55 years); diabetes mellitus was more frequent (37% -vs- 21%); systemic hypertension (by history) was more frequent (59% -vs- 32%); the mean body mass index was higher (29.2 kg/m(2) -vs- 26.5 kg/m(2)), and mean heart weight was lower in both men (509 g -vs- 549 g) and women (422 g -vs- 454 g). There were insignificant (p >0.05) differences in gender, frequency of massive cardiac adiposity, underlying cardiac condition, frequency of coronary heart disease, and frequency of previous insertion of a left ventricular assist device. In conclusion, certain characteristics of patients having HT at one Texas hospital changed in several respects in 2 time periods corresponding to changes in surgeons doing the HTs.

Mitral Valve Replacement After Failed Mitral Ring Insertion With or Without Leaflet/Chordal Repair for Pure Mitral Regurgitation

Mitral repair operations for correction of pure mitral regurgitation (MR) are generally quite successful. Occasionally, however, the reparative procedure incompletely corrects the MR or the MR recurs. From March 1993 to January 2016, twenty nine patients had mitral valve replacement after the initial mitral repair operation, and observations in them were analyzed. All 29 patients at the repair operation had an annular ring inserted and later (<1 year in 6 and >1 year in 21) mitral valve replacement. The cause of the MR before the repair operation appears to have been prolapse in 16 patients (55%), secondary (functional) in 12 (41%) (ischemic in 5), and infective endocarditis which healed in 1 (3%). At the replacement operation the excised anterior mitral leaflet was thickened in all 29 patients. Some degree of stenosis appeared to have been present in 16 of the 29 patients before the replacement operation, although only 10 had an echocardiographic or hemodynamic recording of a transvalvular gradient; at least 11 patients had restricted motion of the posterior mitral leaflet; 10, ring dehiscence; 2, severe hemolysis; and 2, left ventricular outflow obstruction. In conclusion, there are multiple reasons for valve replacement after earlier mitral repair. Uniformly, at the time of the replacement, the mitral leaflets were thickened by fibrous tissue. Measurement of the area enclosed by the 360° rings and study of the excised leaflet suggest that the ring itself may have contributed to the leaflet scarring and development of some transmitral stenosis.

Frequency of Massive Cardiac Adiposity (Floating Heart) in the Native Hearts of Patients Having Heart Transplantation at a Single Texas Hospital (2013 to 2015) and Comparison of Various Clinical and Morphologic Variables in the Patients With Massive Versus Nonmassive Cardiac Adiposity

Body weight continues to increase worldwide due primarily to the increase in body fat. This study analyzes the frequency of massive adiposity at hearts of patients who underwent heart transplantation (HT) determined by the ability of the heart to float in a container of 10% formaldehyde (because adipose tissue is lighter than myocardium) and compares certain characteristics of those patients with and without floating hearts. The hearts studied at HT during a 3-year period (2013 to 2015) at Baylor University Medical Center were carefully "cleaned" and weighed by the same individual and tested as to their ability to float in a container of formaldehyde, an indication of severe cardiac adiposity. Of the 220 hearts studied, 84 (38%) floated in a container of formaldehyde and 136 (62%) did not. Comparison of the 84 patients with floating hearts to the 136 with nonfloating hearts showed a significant difference in ages, but a nonsignificant difference in gender, body mass index, frequency of systemic hypertension, or diabetes mellitus. The odds of a heart being a floating one was increased in patients with a diagnosis of ischemic cardiomyopathy (unadjusted odds ratio 2.12, 95% CI 1.21 to 3.70). The frequency of massive cardiac adiposity in the native hearts of patients having HT (38%) is striking and appears to have increased in frequency in the recent decades.

Frequency of Massive Cardiac Adiposity (Floating Heart) at Necropsy and Comparison of Clinical and Morphologic Variables With Cases With Nonmassive Cardiac Adiposity at a Single Texas Hospital, 2013 to 2014

Body weight continues to increase worldwide primarily because of the increase in body fat. This study analyzes the frequency of massive adiposity at autopsy determined by the ability of the heart to float in a container of 10% formaldehyde (because adipose tissue is lighter than myocardium) and compares certain findings in the patients with floating to those with nonfloating hearts. The hearts studied at necropsy during a 2-year period (2013 to 2014) at Baylor University Medical Center were carefully "cleaned" and weighed by the same person and tested as to their ability to float in a container of formaldehyde, an indication of severe cardiac adiposity. Of the 146 hearts studied, 76 (52%) floated in a container of formaldehyde and 70 (48%) did not. Comparison of the 76 patients with floating hearts with the 70 with nonfloating hearts showed significant differences in ages (62 ± 13 vs 58 ± 14 years). No significant differences between the 2 groups were found in gender, body mass index, frequency of systemic hypertension or diabetes mellitus, either acute or healed myocardial infarction, or whether death was due to a coronary or a noncoronary condition. A weak correlation was found between body mass index and heart weight in both men and women and in both floating and nonfloating hearts. The massive quantity of cardiac adipose tissue (floating heart) appears to have increased enormously in recent decades in the United States.

Morphologic demonstration of spontaneous and surgical closure of membranous ventricular septal defect

This report demonstrates morphologic features of membranous ventricular septal defect that was closed spontaneously in one patient and operatively in the other.

A review of spontaneous closure of ventricular septal defect

Ventricular septal defect (VSD) is the most common congenital heart malformation and can be detected during the prenatal and postnatal period, in childhood, and in adulthood. Spontaneous closure of VSD can be determined through a variety of methods-echocardiography, Doppler color flow imaging, angiography, auscultation, and cardiac catheterization-and can be proven by pathological evidence at necropsy. There are two major types of VSD, membranous and muscular, as well as the perimembranous variety, which comprises variable portions of the adjacent muscular septum but lacks the membranous septum. VSD appears either as an isolated cardiac defect without other abnormalities or with several complex malformations. It has long been recognized that VSD can close spontaneously, but the incidence of spontaneous VSD closure is still uncertain. Since necropsy study of the hearts with VSD has rarely been reported, information on morphological features of spontaneous VSD closure remains limited. In addition, the mechanisms for spontaneous VSD closure are not fully understood. Herein, we present a brief review of the incidence of spontaneous VSD closure, morphological characteristics of the closure, and the main mechanisms responsible for the closure.

The two extremes of cardiac sarcoidosis and the effect of Prednisone therapy

Described herein are clinical and morphologic findings in 2 patients who underwent heart transplantation because of severe heart failure resulting from cardiac sarcoidosis. Although the explanted hearts in each patient had characteristic gross changes of cardiac sarcoidosis, one patient who had been treated with prednisone, had no residual sarcoid granulomas in the myocardium, whereas the other patient, in whom diagnosis was not made until heart transplantation, had innumerable sarcoid granulomas in her heart. This report suggests that prednisone can eliminate sarcoid granulomas in the heart but that their replacement is by dense fibrous tissue, something also likely the result of the granulomas themselves, creating a situation where the treated (prednisone) and the non-treated sarcoid heart may appear similar by gross examination.

Commonalities of cardiac rupture (left ventricular free wall or ventricular septum or papillary muscle) during acute myocardial infarction secondary to atherosclerotic coronary artery disease

Although mortality rates during acute myocardial infarction (AMI) continue to drop, cardiac rupture (left ventricular free wall [LVFW] or ventricular septum [VS] or papillary muscle [PM] or combination) remains relatively common. The aim was to identify commonalities among patients with AMI complicated by cardiac rupture. During a 22-year period (1993-2014) 64 patients hospitalized for AMI were studied and clinical and morphologic variables in those with (25 patients) - vs - those without (39 patients) cardiac rupture were compared, and previous reports on this topic were reviewed. Compared to the non-rupture cases, the rupture group was significantly older (71 years - vs - 60 years); had a much higher frequency of huge deposits of adipose tissue in the heart (floated in formaldehyde) (88% - vs - 20%) but a lower mean body mass index (28.2 Kg/m(2) - vs - 33.2 Kg/m(2)); a much lower frequency of healed myocardial infarct (scar) (4% - vs - 28%); a lower frequency of diabetes mellitus (24% - vs - 47%), and a higher frequency of thrombolytic therapy during the fatal AMI (32% - vs - 10%). None of the rupture cases had evidence of dilated left ventricular cavities or evidence of heart failure before the AMI complicated by rupture. In conclusion, cardiac rupture appears to account for a high percent of deaths during a first AMI. It most commonly occurs in patients with extremely fatty hearts and in those without evidence of prior heart failure.

Nontraumatic intracerebral hemorrhage unassociated with arterial aneurysmal rupture as a cause of sudden unexpected death

Sudden death from intracerebral hemorrhage was observed in two patients admitted to Baylor University Medical Center at Dallas in a single month. Each had been drinking alcohol at the time of onset of first symptoms. Intracerebral hemorrhage was diagnosed in one patient by computed tomography, but not in the second patient who clinically was diagnosed as having acute coronary syndrome. Both died within 24 hours of onset of symptoms, and autopsy in both disclosed intracerebral hemorrhage, an infrequent cause of sudden death. This report calls attention to intracerebral hemorrhage as a cause of sudden death.

Clues to diagnosing carcinoid heart disease as the cause of isolated right-sided heart failure

Described herein is a 67-year-old woman who underwent replacement of both tricuspid and pulmonic valves because of severe isolated right-sided systolic heart failure. The cause of the heart failure preoperatively was believed to be the result of left breast radiation a year earlier. At operation, however, the pulmonic valve was excised and a biopsy of the stiff-walled right atrium was performed, and histologic examination of each was classic of carcinoid heart disease. She never awoke postoperatively. Postoperatively, computed tomography disclosed numerous masses in the liver. Retrospectively, clues to the presence of carcinoid heart disease include thickening of both the tricuspid and pulmonic valve leaflets by echocardiogram, a pressure gradient, albeit small, across the pulmonic valve, the plastering of the septal tricuspid-valve leaflet to the ventricular septum, the total absence of left-sided heart disease, and the presence of extremely low 12-lead QRS electrocardiographic voltage.

Secondary arrhythmogenic right ventricular cardiomyopathy decades after operative repair of tetralogy of Fallot

We describe a 47-year-old man who underwent heart transplantation (HT) for severe right-sided heart failure and periodic episodes of ventricular tachycardia (VT) 43 years after operative repair of tetralogy of Fallot (T of F). The right-ventricular outflow tract, the site where a patch had been placed 4 decades earlier, was aneurysmal. Such development decades after operative repair of T of F of both aneurysm and episodes of VT is probably more common than previously realized.

Identification of novel mutations in the VPS33B gene involved in arthrogryposis, renal dysfunction, and cholestasis syndrome

Arthrogryposis, renal dysfunction, and cholestasis (ARC) syndrome is an autosomal recessive disorder caused by mutations in the VPS33B and VIPAS39. Here, we report novel mutations identified in four patients with ARC syndrome. We analyzed the entire coding regions of the VPS33B and VIPAS39 genes by direct sequencing. To detect novel splice site mutations, mRNA transcripts were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and sequencing. All four patients had compound heterozygous variants in the VPS33B gene. One patient had a previously reported splice site variant with unknown significance, c.239+5G>A, and a novel nonsense mutation, c.621G>A. The other three patients had the c.403+2T>A mutation, and each of them carried one of the splice site variants, c.239+5G>A or c.499-11G>A. c.239+5G>A and c.499-11G>A created novel splice sites which resulted in abnormal transcripts. No significant VIPAS39 mutation was detected in all patients. In patients suspected with ARC syndrome, mutation analysis of the VPS33B gene should be employed as a primary diagnostic test before performing invasive testing procedures such as organ biopsies. Performing mRNA analysis can be useful in predicting the pathogenic phenotype when the mutation seems to affect a normal splicing mechanism.

Morphologic features of the recipient heart in patients having cardiac transplantation and analysis of the congruence or incongruence between the clinical and morphologic diagnoses

Cardiac transplantation (CT) has been one of the great medical advances of the last nearly 50 years. We studied the explanted hearts of 314 patients having CT at Baylor University Medical Center Dallas from 1993 to 2012, and compared the morphologic diagnoses to the clinical diagnoses before CT. Among the 314 patients the morphologic and clinical diagnoses were congruent in 272 (87%) and incongruent in 42 (13%). Most of the incongruity occurred among the 166 patients with non-ischemic cardiomyopathy (non-IC) (36/166 [22%]), and of that group the major incongruity occurred among the patients with hypertrophic cardiomyopathy (7/17 [41%]), non-compaction left ventricular cardiomyopathy (NCLVC) (3/3 [100%]), mononuclear myocarditis (3/3 [100%]), arrhythmogenic right ventricular cardiomyopathy (ARVC) (4/4 [100%]), and cardiac sarcoidosis (8/8 [100%]). The phrase "non-IC" is a general term that includes several subsets of cardiac diseases and simply means "insignificant narrowing of 1 or more of the epicardial coronary arteries," but it does not specify the specific cause of the heart failure leading to CT. A number of cardiac illustrations are provided to demonstrate the morphologic variability occurring among the patients with IC and non-IC.

Fat in the ventricular septum

Described herein is a 68-year-old man who underwent cardiac transplantation for severe chronic heart failure resulting from ischemic cardiomyopathy. Examination of the excised heart showed not only extensive left ventricular scarring but also a huge collection of adipose tissue in the subepicardial region and surprisingly also in the ventricular septum. The finding of fat in the ventricular septum is extremely rare and prompted this report.

Cardiac restriction secondary to massive calcific deposits in the left ventricular cavity

Described herein are clinical and necropsy findings in a 61-year-old woman with fatal left ventricular diastolic failure secondary to massive calcific deposits primarily within the left ventricular cavity. At age 3, an isthmic aortic coarctation was resected, and at age 44, a stenotic congenitally bicuspid aortic valve was replaced. The cause of the intracavitary calcific deposits remains unclear, but surgical resection of the deposits has been an effective form of therapy.

Comparison of the frequency and level of serum total cholesterol >300 mg/dL in patients at the same Texas hospital in a single month in 1993 and in 2013

The clinical pathology laboratory database of a large tertiary hospital in Dallas, Texas, was searched for patients having a serum total cholesterol > 300 mg in a single month in 1993 and in 2013. In September 1993, 63 patients had a serum total cholesterol > 300 mg/dL (range 302-1515 [mean 431, median 349]), and in September 2013, 12 patients had serum total cholesterol levels > 300 mg/dL (range 303-442 [mean 334, median 316.5]), an 81% decline in the numbers of patients and a 23% decline in the average total cholesterol levels during the 20-year period.

Morphologic features of cardiac sarcoidosis in native hearts of patients having cardiac transplantation

Described herein are 10 patients who underwent cardiac transplantation (CT) for severe chronic systolic heart failure resulting from cardiac sarcoidosis. None had the diagnosis of sarcoidosis established before CT except for the 3 patients who earlier had had a portion of left ventricular wall excised for insertion of a left ventricular assist device and non-caseating granulomas were present in the removed myocardium. Although none of the 10 patients had significant narrowing of any of the epicardial coronary arteries, all had focal scarring of the walls of the left and right ventricles and ventricular septum and all had dilated ventricular cavities. The patients with the most ventricular wall scarring tended to have the fewest sarcoid granulomas in the ventricular walls. Two patients had no sarcoid granulomas in the excised heart although one did have typical sarcoid granulomas in the portion of left ventricular wall excised to insert a left ventricular assist device. Patients with cardiac sarcoidosis severe enough to warrant CT had characteristic cardiac ventricular morphologic findings, and no dysfunction of other non-cardiac organs, making clinical diagnosis of cardiac sarcoidosis rather difficult.

Comparison of total 12-lead QRS voltage in a variety of cardiac conditions and its usefulness in predicting increased cardiac mass

Echocardiography provides a more accurate method to determine increased cardiac mass than does electrocardiography. Nevertheless, most offices of physicians do not possess echocardiographic machines, but many possess electrocardiographic machines. Many electrocardiographic criteria have been used to determine increased cardiac mass, but few of the criteria have been measured against cardiac weight determined at necropsy or after cardiac transplantation. Such was the purpose of the present study. Cardiac weight at necropsy or after transplantation was determined in 359 patients with 11 different cardiac conditions, and total 12-lead electrocardiographic QRS voltage (from the peak of the R wave to the nadir of either the Q or the S wave, whichever was deeper) was measured in each patient. Even in hearts with massively increased cardiac mass (>1,000 g), the total 12-lead QRS voltage was clearly increased (>175 mm) in only 94%, but this criterion was superior to that of previously described electrocardiographic criteria for "left ventricular hypertrophy." Hearts with excessive adipose tissue infrequently had increased total 12-lead QRS voltage despite increased cardiac weight. Likewise, patients with fatal cardiac amyloidosis had hearts of increased weight but quite low total 12-lead QRS voltage. In conclusion, 12-lead QRS voltage is useful in predicting increased cardiac mass, but that predictability is dependent in part on the cause of the increased cardiac mass.

Dramatically different phenotypic expressions of hypertrophic cardiomyopathy in male cousins undergoing cardiac transplantation with identical disease-causing gene mutation

Described herein are certain findings in 2 male cousins who underwent cardiac transplantation for severe heart failure (HF), one of the diastolic type (ejection fraction ≈65%), and one of the systolic type (ejection fraction ≈20%), both the consequence of hypertrophic cardiomyopathy (HC), and each had identical disease-causing gene mutations. The implanted heart in one had normal-sized ventricular cavities and no grossly visible ventricular wall lesions (except in one papillary muscle) and the other patient had severely dilated ventricular cavities and multiple extensive ventricular wall scars. The heart mass and the age of onset of symptoms was similar in each patient. A number of other family members had evidence of HC.

Combined congenitally bicuspid aortic valve and mitral valve prolapse causing pure regurgitation

Described herein is a patient with a purely regurgitant congenitally bicuspid aortic valve and a purely regurgitant prolapsing mitral valve. Although it is well established that the bicuspid aortic valve is a congenital anomaly, it is less well appreciated that mitral valve prolapse is almost certainly also a congenital anomaly. The two occurring in the same patient provides support that mitral valve prolapse is also a congenital anomaly.

Natural history of adults with congenitally malformed aortic valves (unicuspid or bicuspid)

Appreciation of the frequency of the congenitally malformed aortic valve has come about during the last 50 years, a period during which aortic valve replacement became a predictably successful operation. Study of patients at necropsy with either a congenitally unicuspid (1 true commissure) or bicuspid (2 true commissures) valve in whom no aortic valve operation has been performed has not been conducted during these 50 years, to our knowledge. We studied 218 patients at necropsy with congenitally malformed aortic valves: 28 (13%) had a unicuspid valve and 190 (87%), a bicuspid valve. Their ages at death ranged from 21 to 89 years (mean, 55 yr), and 80% were men. Of the 218 adults, the aortic valve functioned normally during life in 54 (25%) and abnormally in 164 (75%): aortic stenosis in 142 (65%), pure aortic regurgitation without superimposed infective endocarditis (IE) in 2 (1%), and IE superimposed on a previously normally functioning aortic valve in 20 (9%). IE occurred in a total of 31 (14%) of the 218 patients: involving a previously normally functioning valve in 20 (65%) and a previously stenotic valve in 11 (35%). Of the 218 patients, at least 141 (65%) died as a consequence of aortic valve disease (124 patients) or ascending aortic tears with or without dissection (17 patients). An estimated 1% of the population, maybe higher in men, has a congenitally malformed aortic valve. Data from this study suggest that about 75% of them will develop a major complication. Conversely, and encouragingly, about 25% will go through life without a complication.

Acute aortic dissection with tear in ascending aorta not diagnosed until necropsy or operation (for another condition) and comparison to similar cases receiving proper operative therapy

Acute aortic dissection (AD) with a tear in ascending aorta (AA) is recognized to masquerade occasionally as another condition, and therefore the proper diagnosis is never made or made too late. During a recent 3-year period (2009 to 2011) at Baylor University Medical Center at Dallas, 30 patients with acute AD with tear in AA were diagnosed: 23 (77%) were diagnosed clinically and underwent proper urgent operative therapy; the remaining 7 (23%) with AD with tear in AA were not diagnosed until operation (for another condition) or necropsy or retrospectively by review of antemortem computed tomographic scan after death. The number of patients with AD from tear in AA whose cardiac condition was not diagnosed clinically and who died in the hospital but did not have an autopsy is unclear. Because the autopsy rate in most United States hospitals, including Baylor University Medical Center, is now <5%, many cases of AD are probably not diagnosed and thus its frequency is being underestimated. In conclusion, ≥ 7 of 30 patients (23%) with acute AD with a tear in AA were not diagnosed until necropsy or operation (for another condition) or retrospectively by computed tomography during a 3-year period at a large tertiary medical center showing that this condition continues to be underdiagnosed, and when not diagnosed correctly is usually rapidly fatal. Because the autopsy rate today is so low, the percentage not diagnosed clinically is probably >23%.

Frequency of congenitally bicuspid aortic valves in patients ≥80 years of age undergoing aortic valve replacement for aortic stenosis (with or without aortic regurgitation) and implications for transcatheter aortic valve implantation

The purpose of the present report was to determine the frequency of a congenitally bicuspid aortic valve in patients ≥80 years of age old with aortic stenosis (AS) severe enough to warrant aortic valve replacement. Transcatheter aortic valve implantation (TAVI) has traditionally been reserved for patients ≥80 years of age with severe AS involving a 3-cuspid aortic valve. Traditionally, AS involving a 2-cuspid aortic valve has been a contraindication to TAVI. We examined operatively excised stenotic aortic valves in 364 patients aged ≥80 years to determine the frequency of an underlying congenitally bicuspid aortic valve. Of the 347 octogenarians and 17 nonagenarians, 78 (22%) and 3 (18%) had stenotic congenitally bicuspid aortic valves, respectively. In conclusion, because the results of TAVI are less favorable in patients with stenotic congenitally bicuspid valves than in patients with stenotic tricuspid aortic valves, proper identification of the underlying aortic valve structure is important when considering TAVI as a therapeutic procedure for AS in older patients.

Effect of coronary bypass and valve structure on outcome in isolated valve replacement for aortic stenosis

Reports differ regarding the effect of concomitant coronary artery bypass grafting (CABG) in patients who undergo aortic valve replacement (AVR) for aortic stenosis (AS), and no reports have described the effect of aortic valve structure in patients who undergo AVR for AS. A total of 871 patients aged 24 to 94 years (mean 70) whose AVR for AS was their first cardiac operation, with or without first concomitant CABG, were included. Patients who underwent mitral valve procedures were excluded. In comparison with the 443 patients (51%) who did not undergo CABG, the 428 (49%) who underwent concomitant CABG were significantly older, were more often male, had lower transvalvular peak systolic pressure gradients and larger valve areas, had lower frequencies of congenitally malformed aortic valves, had lighter valves by weight, had higher frequencies of systemic hypertension, and had longer stays in the hospital after AVR. Early and late (to 10 years) mortality were similar by propensity-adjusted analysis in patients who did and did not undergo concomitant CABG. Congenitally unicuspid or bicuspid valves occurred in approximately 90% of those aged 21 to 50, in nearly 70% in those aged 51 to 70 years, and in just over 30% in those aged 71 to 95 years. Unadjusted and adjusted survival was significantly higher in patients with unicuspid or bicuspid valves compared to those with tricuspid valves. In conclusion, although concomitant CABG had no effect on the adjusted probability of survival, the type of aortic valve (unicuspid or bicuspid vs tricuspid) significantly affected the unadjusted and adjusted probability of survival.

Presence of a congenitally bicuspid aortic valve among patients having combined mitral and aortic valve replacement

Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent. During examination of operatively excised aortic and mitral valves because of dysfunction (stenosis and/or regurgitation), we encountered 16 patients who had congenitally bicuspid aortic valves associated with various types of dysfunctioning mitral valves. Eleven of the 16 patients had aortic stenosis (AS): 5 of them also had mitral stenosis, of rheumatic origin in 4 and secondary to mitral annular calcium in 1; the other 6 with aortic stenosis had pure mitral regurgitation (MR) secondary to mitral valve prolapse in 3, to ischemia in 2, and to unclear origin in 1. Of the 5 patients with pure aortic regurgitation, each also had pure mitral regurgitation: in 1 secondary to mitral valve prolapse and in 4 secondary to infective endocarditis. In conclusion, various types of mitral dysfunction severe enough to warrant mitral valve replacement occur in patients with bicuspid aortic valves. A proper search for mitral valve dysfunction in patients with bicuspid aortic valves appears warranted.

Effect of body mass index on survival in patients having aortic valve replacement for aortic stenosis with or without concomitant coronary artery bypass grafting

The purpose of this report is to describe the effect of body mass index (BMI) on 30-day and late outcome in patients having aortic valve replacement (AVR) for aortic stenosis (AS) with or without concomitant coronary artery bypass grafting. From January 2002 through June 2010 (8.5 years), 1,040 operatively excised stenotic aortic valves were submitted to the cardiovascular laboratory at Baylor University Medical Center at Dallas. Of the 1,040 cases 175 were eliminated because they had a previous cardiac operation. The present study included 865 adults whose AVR for AS was their first cardiac operation. Propensity-adjusted analysis showed that 30-day and late mortality were strongly and significantly associated with BMI. Decreased risk of 30-day and long-term mortality was observed for patients with BMI in the low 30s compared to patients with BMI in the mid 20s or >40 kg/m(2). In conclusion, the findings in this study indicate a strong and significant adjusted association between BMI and 30-day and long-term mortality in patients having AVR for AS with or without concomitant coronary artery bypass grafting. Better survival was observed in patients with BMIs in the low 30s compared to patients with BMIs in the mid 20s and >40 kg/m(2).

Aortic medial elastic fiber loss in acute ascending aortic dissection

The cause of acute aortic dissection continues to be debated. One school of thought suggests that underlying aortic medial cystic necrosis is the common denominator. The purpose of the present study was to determine if there was loss and, if so, how much loss of medial elastic fibers in the ascending aorta in patients with acute aortic dissection with the entrance tear in the ascending aorta. We examined operatively excised ascending aortas in 69 patients having acute dissection with tears in the ascending aorta. Patients with previous aortotomy, healed dissection, and connective tissue disorders were excluded. The 69 patients' ages ranged from 31 to 88 years (mean 56); 49 were men and 20 were women. Loss of aortic medial elastic fibers was graded as 0 (no loss), 1+ (trace), 2+ (mild), 3+ (moderate), and 4+ (full thickness loss). Of these 69 patients, 56 (82%) had 0 or 1+ elastic fiber loss; 13 patients (18%), 2+ to 4+ loss including 4 with 2+, 6 with 3+, and 2 with 4+. Nearly all patients (97%) had a history of systemic hypertension and/or had received antihypertensive drug therapy. In conclusion, most patients (82% in this study) having acute aortic dissection with entrance tears in the ascending aorta have normal numbers or only trace loss of aortic medial elastic fibers. Thus, underlying abnormal ascending aortic structure uncommonly precedes acute dissection.

Diagnosing cardiac sarcoidosis clinically without tissue confirmation

A 52-year-old woman is described in whom cardiac sarcoidosis was diagnosed clinically on the basis of high-grade heart block, recurring ventricular tachyarrhythmias, and acute cardiac decompensation. Confirmation of sarcoidosis was not determined until necropsy. When it causes cardiac dysfunction, sarcoidosis rarely causes dysfunction of another body organ, although small sarcoid granulomas may also be present in noncardiac organs or tissues. In the present patient, neurosarcoidosis accompanied the cardiac sarcoidosis, but it was the latter that produced the life-threatening symptoms and was fatal.

Examination of isolated ventricular noncompaction (hypertrabeculation) as a distinct entity in adults

Three patients (2 women) 36, 45, and 49 years of age underwent cardiac transplantation for what was diagnosed clinically as nonischemic dilated cardiomyopathy. Examination of the transthoracic echocardiogram and explanted heart in each disclosed marked hypertrabeculation involving the free wall of the very dilated left ventricle, a finding consistent with what has been termed "isolated ventricular noncompaction" (IVNC). Although these 3 cases anatomically fulfilled the echocardiographic definition of IVNC, review of previous publications containing gross photographs of the heart suggests that IVNC is overdiagnosed at least morphologically.

"Repaired" tetralogy of fallot mimicking arrhythmogenic right ventricular cardiomyopathy (another phenocopy)

Described is a 41-year-old man who at age 6 had partial resection of an obstructed right ventricular outflow tract with insertion of a patch and closure of a ventricular septal defect (tetralogy of Fallot). At age 41, cardiac transplantation was performed because of right ventricular outflow patch aneurysm, numerous episodes of ventricular tachycardia, and chronic heart failure, all features of the familial form of arrhythmogenic right ventricular cardiomyopathy (ARVC). Additionally, the patient had bundle branch block and epsilon waves on electrocardiogram, other features of ARVC. The case is described to introduce the concept of acquired ARVC, because the patient had many of the clinically recognized features of familial ARVC.

Carcinoid heart disease without the carcinoid syndrome but with quadrivalvular regurgitation and unsuccessful operative intervention

A 53-year-old woman is described who underwent mitral and aortic valve replacement and tricuspid valve annuloplasty for pure regurgitation at all 3 valve sites for unrecognized carcinoid heart disease without the carcinoid syndrome 22 days before death. Metastatic carcinoid was not recognized until necropsy, which disclosed a probable ovarian primary but with large hepatic metastases and left-sided cardiac involvement either greater than or equal to the right-sided involvement. Pulmonary hypertension, very unusual in carcinoid heart disease, persisted postoperatively and probably played a role in the patient's early death. Hepatic metastasis with ovarian primary is most unusual in this circumstance.

Comparison of the structure of the aortic valve and ascending aorta in adults having aortic valve replacement for aortic stenosis versus for pure aortic regurgitation and resection of the ascending aorta for aneurysm

BACKGROUND

There is debate concerning whether an aneurysmal ascending aorta should be replaced when associated with a dysfunctioning aortic valve that is to be replaced. To examine this issue, we divided the patients by type of aortic valve dysfunction-either aortic stenosis (AS) or pure aortic regurgitation (AR)-something not previously undertaken.

METHODS AND RESULTS

Of 122 patients with ascending aortic aneurysm (unassociated with aortitis or acute dissection), the aortic valve was congenitally malformed (unicuspid or bicuspid) in 58 (98%) of the 59 AS patients, and in 38 (60%) of the 63 pure AR patients. Ascending aortic medial elastic fiber loss (EFL) (graded 0 to 4+) was zero or 1+ in 53 (90%) of the AS patients, in 20 (53%) of the 38 AR patients with bicuspid valves, and in all 12 AR patients with tricuspid valves unassociated with the Marfan syndrome. An unadjusted analysis showed that, among the 96 patients with congenitally malformed valves, the 38 AR patients had a significantly higher likelihood of 2+ to 4+ EFL than the 58 AS patients (crude odds ratio: 8.78; 95% confidence interval: 2.95, 28.13).

CONCLUSIONS

These data strongly suggest that the type of aortic valve dysfunction-AS versus pure AR-is very helpful in predicting loss of aortic medial elastic fibers in patients with ascending aortic aneurysms and aortic valve disease.

Aortic valve replacement for stenosis with or without coronary artery bypass grafting after 2 previous isolated coronary artery bypass grafting operations

Aortic valve replacement following an earlier coronary artery bypass grafting (CABG) procedure is fairly common. When this situation occurs, the type of valve dysfunction is usually stenosis (with or without regurgitation), and whether it was missed at the time of the earlier CABG or developed subsequently is usually unclear. We attempted to determine the survival in patients who had had aortic valve replacement after 2 previous CABG procedures. We describe 12 patients who had aortic valve replacement for aortic stenosis; rather than one previous CABG operation, all had had 2 previous CABG procedures. Only one patient died in the early postoperative period after aortic valve replacement, and the remaining 11 were improved substantially: all have lived at least 11 months, and one is still alive at over 101 months after aortic valve replacement. Aortic valve replacement remains beneficial for most patients even after 2 previous CABG procedures.

Some previously neglected examples of arrhythmogenic right ventricular dysplasia/cardiomyopathy and frequency of its various reported manifestations

Four patients are described with either parchment-like thinning or partial but extensive myocyte depletion with severe fatty or fibrofatty infiltration of the free wall of the right ventricle in its outflow tract, including 2 previously reported patients who also had focal parchment-like thinning of the left ventricular free wall. Three had documented ventricular tachycardia, and the remaining patient had sudden death as his first and only manifestation of heart disease. Three patients had severe heart failure: in 1, it was fatal, and the other 2 underwent cardiac transplantation. Necropsy cases of parchment-heart syndrome before 1980 are reviewed, as well as large series of cases with arrhythmogenic right ventricular dysplasia (ARVD) reported subsequently. It is suggested that ARVD is not an ideal name for this condition, because malignant ventricular arrhythmias are not universal, the left ventricular free wall and/or ventricular septum are sometimes involved, and the name "ARVD" neglects the fact that severe heart failure may be prominent in these patients. The right ventricular wall can be thin or parchment-like, or it may not be thinned but consist mainly of adipose tissue with or without focal fibrous tissue and a few islands of myocytes. Nevertheless, because the name "ARVD" has been commonly used and recognized for >30 years, it is probably best retained for this condition.

Skin and bone: the pathogenetic relationship between psoriasis and psoriatic arthritis

Our current understanding of the relationship between psoriasis and psoriatic arthritis remains incomplete, though the evidence from the clinical setting, response to therapeutics, epidemiology, genetics, imaging, and immunopathologic models suggest that they make likely share a common pathogenesis. Psoriatic disease can no longer be thought of as a condition limited to skin and joints. Rather, it must be considered a multi-faceted disorder in which systemic inflammation plays a central role. There is now convincing evidence that individuals with psoriasis have a higher prevalence of co-morbid disease, particularly cardiovascular risk factors, metabolic disorders, and other immune-mediated inflammatory diseases. The cutaneous manifestations of psoriasis place dermatologists in a crucial and privileged role--one that affords us the potential for early detection of associated co-morbid conditions through screening and perhaps impact disease course and clinical outcomes.

Full blown cardiovascular syphilis with aneurysm of the innominate artery

The investigators report the case of a 44-year-old man who presented acutely and was found to have saccular aneurysm of the innominate artery, narrowed or totally occluded aortic arch arteries, and marked thickening of the thoracic aorta except for the wall behind the sinuses of Valsalva. The abdominal aorta was entirely normal. Results of the serologic test for syphilis were strongly positive. Because cardiovascular syphilis appears to be a disease that affects the vasa vasora and because these channels are limited to the thoracic aorta, the abdominal aorta is uninvolved, as demonstrated so nicely in the patient described in this case report. Because most patients with cardiovascular syphilis are much older than the patient described, it is unusual to see a perfectly normal abdominal aorta, as in the present patient. In conclusion, syphilis producing aneurysm of the innominate artery is unusual but is always associated with syphilitic involvement of the thoracic aorta.

Natural history of syphilitic aortitis

No large studies of cardiovascular syphilis at necropsy have been reported since 1964. We examined at necropsy 90 patients who had characteristic morphologic findings of syphilitic aortitis. None had ever undergone cardiovascular surgery. With the exception of 2 cases seen more recently, the hearts and aortas of the 90 patients were examined and categorized by one of us (W.C.R.) from 1966 to 1990. All 90 had extensive involvement of the tubular portion of the ascending aorta by the syphilitic process, which spared the sinuses of Valsalva in all but 4 patients. The aortic arch was also involved in 49 (91%) of 54 patients and the descending thoracic aorta in 47 (90%) of 52 patients. Syphilis was the cause of death in 23 (26%) of the 90 patients. It was secondary to rupture of the ascending or descending thoracic aorta in 12, severe aortic regurgitation leading to heart failure in 10, and severe narrowing of the aortic ostium of the right coronary artery in 1 patient. Of the 40 patients who had undergone serologic testing for syphilis, 28 (70%) had a positive (reactive) finding. Those patients with a negative or nonreactive test or who did not undergo a serologic test for syphilis had morphologic and histologic findings in the aorta at necropsy similar to the findings of those patients who had had a positive serologic test for syphilis. In conclusion, cardiovascular syphilis has not disappeared. In patients with dilated ascending aortas, with or without aortic regurgitation, a serologic test for syphilis is recommended. If the findings are positive or if characteristic morphologic features of cardiovascular syphilis are suspected, irrespective of the results of the serologic tests, antibiotic therapy appears desirable.
