Left ventricular assist devices (LVADs) have revolutionized therapy for patients with Stage D heart failure (HF) with reduced systolic function providing not only improved survival benefits but also meaningful changes in quality of life and functional capacity. With technological advances and improved durability of devices, length of survival has significantly improved. With continued organ donor shortage, LVADs are frequently serving as a substitute for cardiac transplant as destination therapy, particularly among the elderly. Internists not only face the important challenge of identifying the patients in need referral for these advanced therapies, they are also faced with the challenges of taking care of these patients. This review will help the internists to better understand the present status, indications and advances in LVADs and also understand the complications and adverse effects associated with these devices.

Stevens-Johnson syndrome is a rare, severe cutaneous reaction most often associated with drug therapy. Lenalidomide is a derivative of thalidomide used in the treatment of multiple myeloma. We describe a case of Stevens-Johnson syndrome possibly induced by lenalidomide in a 73-year-old Caucasian female undergoing induction therapy for multiple myeloma. After 13 doses of induction therapy, she was admitted to the hospital directly from her oncologist's office after presenting with a diffuse, bodywide, maculopapular rash with desquamation. She had prominent crusting of her lips, erythematous ulcers on her soft palate that could not be distinguished from petechial hemorrhages, and acute kidney injury (serum creatinine concentration 4.6 mg/dl). She was also febrile and hypotensive. Lenalidomide was discontinued, and the patient was treated with intravenous dexamethasone 10 mg every 6 hours and topical corticosteroids. Over the next week, the patient's condition improved, but she had extensive exfoliation of her rash and pruritus that required antihistamine therapy. By hospital day 9, her rash continued to improve, her pruritus resolved, and she was discharged with a tapering dose of oral prednisone. Lenalidomide was switched to bortezomib for her induction therapy, and the patient did not experience any further cutaneous reactions. The results of a skin biopsy concluded that the findings were consistent with a drug hypersensitivity reaction, suspected to be Stevens-Johnson syndrome. Use of the Naranjo adverse drug reaction probability scale indicated a possible relationship (score of 3) between the patient's development of Stevens-Johnson syndrome and lenalidomide therapy. To our knowledge, no published case reports of severe dermatologic reactions, such as Stevens-Johnson syndrome or toxic epidermal necrolysis, to lenalidomide have been reported. Thus, we believe this to be the first published case report of a patient who developed Stevens-Johnson syndrome while receiving lenalidomide for induction therapy for multiple myeloma. Clinicians should have a heightened awareness of the signs and symptoms of these severe skin reactions if their patients are receiving lenalidomide.

ObjectivesIn this study, we have developed an electrocardiogram-based scoring system to predict secondary pulmonary hypertension.DesignA cross-sectional study.SettingSingle tertiary-care hospital in Scranton, Pennsylvania, USA.ParticipantsFive hundred and fifty-two consecutive patients undergoing right heart catheterization between 2006 and 2009.Main outcome measuresSurface electrocardiogram was assessed for R-wave in lead V1 ≥ 6mm, R-wave in V6 ≤ 3mm, S-wave in V6 ≥ 3mm, right atrial enlargement, right axis deviation and left atrial enlargement. Pulmonary hypertension was defined as mean pulmonary artery pressure ≥25 mmHg, determined by right heart catheterization.ResultsA total of 297 (54%) patients in the study cohort had pulmonary hypertension. In total, 332 patients from the study cohort formed the development cohort and the remaining 220 patients formed the validation cohort. In the development cohort, based on log odds ratios of association, RAE, LAE, RAD, R-wave in V1 ≥ 6 mm were assigned scores of 5, 2, 2 and 1, respectively, to form a 10-point scoring system “Scranton PHT (SP) score”. SP scores of 5 points and 7 points in DC showed C-statistic of 0.83 and 0.89, respectively, for discriminating pulmonary hypertension. C-statistic for RAE alone was significantly lower compared to an SP score of 7 (0.83 vs. 0.89, P = 0.021). The reliability of SP score in the validation cohort was acceptable.ConclusionSP score provides a good point-of-care tool to predict pulmonary hypertension in patients with clinical suspicion of it.
