Parkview Pharmacy Department

Anticoagulation with unfractionated heparin during extracorporeal membrane oxygenation (ECMO) is common, but alternative agents are being evaluated for safety and efficacy. The objective of this analysis was to assess if a comprehensive bivalirudin dosing and monitoring protocol effectively guides dose adjustments and monitoring of bivalirudin in patients during ECMO. Our analysis included 11 patients who received bivalirudin during ECMO therapy and had dosing managed using our hospital derived protocol. Patients treated over a 1-year period were included in this retrospective analysis. Clinical characteristics and changes in activated partial thromboplastin time (aPTT) were evaluated from medical records to determine the efficacy …

Cardiac Magnetic Resonance To Evaluate Percutaneous Pulmonary Valve Implantation In Children And Young Adults, Cesar Gonzalez De Alba, Fernando Molina Berganza, John Brownlee, Muhammad Khan, Dilachew Adebo

The Texas Heart Institute Journal

Experience with cardiac magnetic resonance to evaluate coronary arteries in children and young adult patients is limited. Because noninvasive imaging has advantages over coronary angiography, we compared the effectiveness of these techniques in patients who were being considered for percutaneous pulmonary valve implantation.

We retrospectively reviewed the cases of 26 patients (mean age, 12.53 ± 4.85 yr; range, 5–25 yr), all of whom had previous right ventricular-to-pulmonary artery homografts. We studied T2-prepared whole-heart images for coronary anatomy, velocity-encoded cine images for ventricular morphology, and function- and time-resolved magnetic resonance angiographic findings. Cardiac catheterization studies included coronary angiography, balloon compression testing, …

New Pulmonary Valvuloplasty Technique By Use Of An Hourglass-Shaped Balloon In 3 Adults With Severe Pulmonary Valve Stenosis, Teoman Kilic, Tayfun Sahin, Kurtulus Karauzum, Ertan Ural, Wesley R Pedersen

The Texas Heart Institute Journal

Percutaneous balloon pulmonary valvuloplasty is the preferred therapy for pulmonary valve stenosis. However, the designs of the cylindrical balloons historically used for valvuloplasty have limitations, especially in patients who have large pulmonary annular diameters. The hourglass-shaped V8 Aortic Valvuloplasty Balloon may prove to be an effective alternative. The balloon has 2 large bulbous segments that are separated by a narrowed waist. The geometric shape is maintained throughout inflation, improving fixation and enabling broader leaflet opening. We present our first experience with the V8 balloon in 3 adults who had severe, symptomatic pulmonary valve stenosis. In addition to describing their cases, …

Effects Of Older Donor Age And Cold Ischemic Time On Long-Term Outcomes Of Heart Transplantation, Heidi J Reich, Jon A Kobashigawa, Tamar Aintablian, Danny Ramzy, Michelle M Kittleson, Fardad Esmailian

The Texas Heart Institute Journal

Using older donor hearts in cardiac transplantation may lead to inferior outcomes: older donors have more comorbidities that reduce graft quality, including coronary artery disease, hypertension, diabetes mellitus, and dyslipidemia. Shorter cold ischemic times might overcome the detrimental effect of older donor age. We examined the relationship between donor allograft age and cold ischemic time on the long-term outcomes of heart transplant recipients. rom 1994 through 2010, surgeons at our hospital performed 745 heart transplantations. We retrospectively classified these cases by donor ages of(younger) and ≥50 years (older), then by cold ischemic times of(short), 120 to 240 min (intermediate), and …

Cardiac Rehabilitation Improves Cardiometabolic Health In Young Patients With Nonischemic Dilated Cardiomyopathy, Samuel G Wittekind, Yvette Gerdes, Wayne Mays, Clifford Chin, John L Jefferies

The Texas Heart Institute Journal

Nonischemic dilated cardiomyopathy is deadly and costly, and treatment options are limited. Cardiac rehabilitation has proved safe and beneficial for adults with various types of heart failure. Therefore, we retrospectively evaluated the hypothesis that rehabilitation is safe and improves cardiometabolic health in young patients with nonischemic dilated cardiomypathy. From 2011 through 2015, 8 patients (4 males) (mean age, 20.6 ± 6.6 yr; range, 10-31 yr) underwent rehabilitation at our institution. They were in American Heart Association class C or D heart failure and were on maximal medical therapy. Their mean left ventricular ejection fraction at baseline was 0.26 ± 0.15. …
