ABSTRACT
BACKGROUND: Orthotopic heart transplant (OHT) is increasingly used for end-stage heart failure due to cardiac sarcoidosis (CS). However, concern regarding long-term outcomes in patients with CS after OHT persists because of multiorgan involvement. METHODS: Baseline demographics and invasive hemodynamics were measured in 12 patients with CS and 28 patients with nonischemic cardiomyopathy requiring OHT at the time of transplantation, 1 week after OHT, and in routine follow-up. Primary endpoints included changes in pulmonary artery pressure, right ventricular stroke work index, and pulmonary compliance. Secondary endpoints included degree of allograft rejection and death. RESULTS: During a mean follow-up of 73.8 months, no differences in pulmonary artery pressures, right ventricular stroke work index, or cardiac index were observed in patient with CS (n = 12) compared with those without CS (n = 28) between 1 week after OHT and the most recent follow-up. Long-term follow-up showed that pulmonary hemodynamics remained normal in the CS group. International Society for Heart and Lung Transplantation (ISHLT) 1990 grade ≥ 1a rejection occurred less frequently in the CS group (17% vs 68%, P = 0.006), and 0 of 12 patients in the CS group experienced histologic or clinical recurrence of sarcoidosis or ≥2 rejection. Patients with CS had excellent survival after OHT, with 0 deaths or significant rejection. CONCLUSIONS: Patients with CS have similar post-transplant hemodynamics as patients without CS, without evidence of right ventricular dysfunction or pulmonary hypertension. Neither significant rejection nor recurrence of sarcoid in the allograft was observed in this cohort of patients with CS. Survival is similar between patients with CS and those without CS. Heart transplant is a viable strategy in selected patients with CS with excellent outcomes.

OBJECTIVES: We sought to describe the caliber and vascular health of the subclavian and axillary arteries as related to their potential utilization in complex cardiovascular procedures. BACKGROUND: Patients referred for advanced catheter-based therapies frequently have lower extremity peripheral vascular disease that may prohibit the use of large bore arterial catheters. Utilization of the upper extremity peripheral vasculature is rarely considered as an alternative access strategy. This may be due in part to a lack of familiarity with the thoracic vasculature. METHODS AND RESULTS: 208 consecutive patients undergoing routine CTA prior to transcatheter aortic valve replacement were retrospectively evaluated in a systematic analysis of upper and lower extremity vasculature. Minimal luminal diameters (MLDs) for the axillary arteries and iliofemoral arteries were 6.0 ± 1.1 mm and 6.6 ± 1.8 mm respectively. Compared to the iliofemoral arteries, the axillary arteries demonstrated substantially lower rates of significant stenosis (2% vs. 12%, p < 0.01) and significantly lower rates of moderate to severe calcification disease (9% vs. 64%, p < 0.01). Diabetes and tobacco use were independently associated with smaller axillary artery caliber by MLD (p < 0.01) but not with significant stenotic disease. CONCLUSIONS: The axillary arteries are slightly smaller but less frequently diseased than the corresponding iliofemoral vessels.

Infertility affects approximately 10% to 20% of reproductive-age couples, many of whom may present initially to a urologist. Some couples may be treated medically to increase spontaneous conception rates; however, many will require more aggressive management with in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI). IVF involves ovarian stimulation, oocyte retrieval, and fertilization outside of the body; ICSI involves injecting one sperm into the oocyte to promote fertilization. Here we provide a brief overview of IVF and ICSI along with a discussion of the risks involved to facilitate the counseling and care of the infertile couple.
