Background The study compared downstream coronary and conduit disease progression in the left anterior descending coronary artery treated with coronary artery bypass grafting using the left internal mammary artery ( LIMA ) versus percutaneous coronary intervention with bare metal stent ( BMS ) or drug eluting stent ( DES ). Methods and Results A total of 12 301 consecutive patients underwent isolated primary coronary revascularization, of which 2386 met our inclusion criteria (Percutaneous coronary intervention, n=1450; coronary artery bypass grafting, n=936). Propensity score analysis matched 628 patients, of which 468 were treated to the left anterior descending with coronary artery bypass grafting with LIMA (n=314), percutaneous coronary intervention with BMS (n=94), and DES (n=60). Coronary angiograms were analyzed by quantitative coronary angiography ( QCA ; n=433). Cumulative downstream coronary and conduit disease progression were estimated by Kaplan–Meier method and effect of treatment type by Cox proportional hazard models. Patients treated with LIMA had significantly lower risk of downstream coronary disease progression at follow‐up angiogram compared with BMS and DES (hazard ratio [ HR ] [95% CI ], 0.34; [0.20–0.59]; P =0.0002; and HR [95% CI ], 0.39; [0.20–0.79]; P =0.01, respectively). LIMA was associated with a lower risk of conduit disease progression compared to BMS and DES ( HR [95% CI ], 0.18; [0.12–0.28]; P <0.001; and HR [95% CI ], 0.27; [0.16–0.46]; P <0.001, respectively). BMS was associated with higher HR for downstream coronary and conduit disease progression compared with DES , but the difference did not reach statistical significance ( HR [95% CI], 1.13; [0.57–2.36]; P =0.73; and HR [95% CI ], 1.46; [0.88–2.50]; P =0.14, respectively). Conclusions LIMA grafting to left anterior descending is associated with significantly lower risk of downstream coronary and conduit disease progression compared to percutaneous coronary intervention with BMS and DES .

BACKGROUND Hidradenitis suppurativa (HS) is a progressive, recurrent inflammatory disorder. OBJECTIVE To assess long-term satisfaction and postoperative perceptions among patients who underwent surgical management of HS. MATERIALS AND METHODS A questionnaire was mailed to 499 HS surgical patients to assess surgical outcome, satisfaction, and quality of life. RESULTS Of the 499 questionnaires mailed, 113 were returned (22.6% response rate) and 2 were excluded for redundancy. Of the 111 respondents, 65 (58.6%) were female, 91 (82.0%) had Hurley Stage III disease, 88 (79.3%) were treated with excision and 23 (20.7%) with unroofing, 45 (40.5%) had perianal or perineal disease, and 41 (36.9%) had axillary disease. Most patients were satisfied or very satisfied with their surgical results (84.7%; 94 of 111), were glad they underwent surgery (96.3%; 105 of 109), and would recommend surgery to a friend or relative (82.6%; 90 of 109). Most patients were satisfied or very satisfied with the appearance of their healed wound (62.4%; 68 of 109). Retrospective mean quality of life increased significantly from 5 preoperatively to 8.4 postoperatively (p < .001). CONCLUSION Hidradenitis suppurativa surgical management was well regarded by patients and should be considered by future patients to limit the morbidity of HS.

BACKGROUND The incidence of rare cutaneous malignancies is unknown. Current estimates of rare cutaneous malignancy incidences are based on broad epidemiologic data or single institution experiences, not population-based data. OBJECTIVE To determine the incidence of several rare nonmelanoma skin cancers. MATERIALS AND METHODS The authors conducted a retrospective chart review of a population-based cohort between the years 2000 and 2010. Residents of Olmsted County, Minnesota, who were diagnosed with a biopsy-proven nonmelanoma skin cancer—excluding basal cell carcinoma and squamous cell carcinoma—were included in this study. The primary outcome was tumor incidence. Additionally, the authors extracted patient demographics, tumor characteristics, treatment modalities, and outcomes. RESULTS The age-adjusted and sex-adjusted incidences per 100,000 persons of multiple rare cutaneous malignancies were: atypical fibroxanthoma (1.8), sebaceous carcinoma (0.8), dermatofibrosarcoma protuberans (0.4), microcystic adnexal carcinoma (0.7), eccrine carcinoma (0.4), eccrine porocarcinoma (0.2), and leiomyosarcoma (0.2). CONCLUSION The authors report population-based incidences and clinical characteristics for these rare cutaneous malignancies. The immune status and smoking status of patients and the treatment and outcomes of these tumors are reported. Additional studies in a broader population are needed to further define the epidemiology and outcomes of these malignancies.

Background In adult Fontan patients, ventricular or arterial dysfunction may impact homeostasis of the Fontan circulation and predispose to heart failure. We sought to characterize ventricular‐arterial ( VA ) properties in adult Fontan patients. Methods and Results Adult Fontan patients (n=170), including those with right ( SRV , n=57) and left ( SLV , n=113) dominant ventricular morphology, were compared to age, sex, and body size matched controls (n=170). Arterial function, load‐insensitive measures of contractility, VA coupling, diastolic function, and ventricular efficiency were assessed. Compared to controls, Fontan patients had similar arterial (Ea), but lower end‐systolic ventricular (Ees), elastance, preload recruitable stroke work and peak power index, impaired VA coupling, eccentric remodeling, reduced ventricular efficiency and increased diastolic stiffness ( P <0.05 for all). Ventricular efficiency declined steeply with higher heart rate in Fontan, but not control, patients. Among Fontan patients (n=123) and controls (n=162) with preserved cardiac index ( CI ; ≥2.5 L/min per m 2 ), Fontan patients had worse contractility than controls, but CI was preserved owing to relative tachycardia, lower afterload, and eccentric remodeling. However, 25% of Fontan patients had reduced CI and were distinguished from those with preserved CI by less‐eccentric remodeling and worse diastolic function, rather than more‐impaired contractility. Conclusions Adult Fontan patients have contractile and diastolic dysfunction with normal afterload, impaired VA coupling, and reduced ventricular efficiency with heightened sensitivity to heart rate. Maintenance of CI is dependent on lower afterload, eccentric remodeling, and relative preservation of diastolic function. These data contribute to our understanding of circulatory physiology in adult Fontan patients.

Clinical introduction A 77-year-old female was referred for evaluation of an episode of syncope while eating breakfast. There was no history of fall, syncope, prodrome, dyspnoea, chest discomfort or palpitations. Medical history was notable for hyperlipidaemia and treated hypertension. Blood pressure was 140/90 mm Hg, pulse 85 beats per minute (BPM). No murmurs were present on cardiac examination. ECG revealed normal sinus rhythm with left ventricular (LV) hypertrophy (see online supplementary figure S1). Holter monitor demonstrated rare premature ventricular complexes (<1% of beats), without heart block or ventricular tachycardia. Transthoracic echocardiogram is shown in figure 1. Question Which of the following is the explanation for the flow indicated by the yellow arrow? Aortic stenosis Coronary artery flow, indicative of coronary fistula Hypertrophic cardiomyopathy with apical pouch Hypertensive heart disease Mitral stenosis
