Non-thrombotic PE does not represent a distinct clinical syndrome. It may be due to a variety of embolic materials and result in a wide spectrum of clinical presentations, making the diagnosis difficult. With the exception of severe air and fat embolism, the haemodynamic consequences of non-thrombotic emboli are usually mild. Treatment is mostly supportive but may differ according to the type of embolic material and clinical severity.

Guidelines on the Diagnosis and Management of Acute Pulmonary Embolism: The Task Force for the Diagnosis and Management of Acute Pulmonary Embolism of the European Society of Cardiology (ESC)

Background Primary pulmonary hypertension is a progressive disease for which no treatment has been shown in a prospective, randomized trial to improve survival. Methods We conducted a 12-week prospective, randomized, multicenter open trial comparing the effects of the continuous intravenous infusion of epoprostenol (formerly called prostacyclin) plus conventional therapy with those of conventional therapy alone in 81 patients with severe primary pulmonary hypertension (New York Heart Association functional class III or IV). Results Exercise capacity was improved in the 41 patients treated with epoprostenol (median distance walked in six minutes, 362 m at 12 weeks vs. 315 m at base line), but it decreased in the 40 patients treated with conventional therapy alone (204 m at 12 weeks vs. 270 m at base line; P<0.002 for the comparison of the treatment groups). Indexes of the quality of life were improved only in the epoprostenol group (P<0.01). Hemodynamics improved at 12 weeks in the epoprostenol-treated pat...

A Comparison of Continuous Intravenous Epoprostenol (Prostacyclin) with Conventional Therapy for Primary Pulmonary Hypertension

The heme oxygenases, which consist of constitutive and inducible isozymes (HO-1, HO-2), catalyze the rate-limiting step in the metabolic conversion of heme to the bile pigments (i.e., biliverdin and bilirubin) and thus constitute a major intracellular source of iron and carbon monoxide (CO). In recent years, endogenously produced CO has been shown to possess intriguing signaling properties affecting numerous critical cellular functions including but not limited to inflammation, cellular proliferation, and apoptotic cell death. The era of gaseous molecules in biomedical research and human diseases initiated with the discovery that the endothelial cell-derived relaxing factor was identical to the gaseous molecule nitric oxide (NO). The discovery that endogenously produced gaseous molecules such as NO and now CO can impart potent physiological and biological effector functions truly represented a paradigm shift and unraveled new avenues of intense investigations. This review covers the molecular and biochemical characterization of HOs, with a discussion on the mechanisms of signal transduction and gene regulation that mediate the induction of HO-1 by environmental stress. Furthermore, the current understanding of the functional significance of HO shall be discussed from the perspective of each of the metabolic by-products, with a special emphasis on CO. Finally, this presentation aspires to lay a foundation for potential future clinical applications of these systems.

The International Society of Heart and Lung Transplantation Guidelines for the care of heart transplant recipients

Cytomegalovirus (CMV) infection and disease are important causes of morbidity and mortality among transplant recipients. For the purpose of developing consistent reporting of CMV in clinical trials, definitions of CMV infection and disease were developed and published. This study seeks to update the definitions of CMV on the basis of recent developments in diagnostic techniques, as well as to add to these definitions the concept of indirect effects caused by CMV.

Definitions of Cytomegalovirus Infection and Disease in Transplant Recipients

We wanted to determine whether there is any advantage of using a mitral tissue valve, when aortic and mitral valves are simultaneously replaced. We placed a tissue valve in the mitral position and a mechanical valve in the aortic position in 22 cases (combined group). In 31 other double valve replacements, mechanical prostheses were chosen for both positions (mechanical group). The mean follow-up time for the combined group was 8.9 years, and that for the mechanical group was 7.2 years. The 10-year survival rate and freedom from thromboembolism at 10 years were not different in the two groups. Treatment-related hemorrhage was seen in 3 patients of the combined group alone. Five patients among the combined group underwent reoperation because of bioprosthetic dysfunction, and the rate of freedom from reoperation at 10 years was 75 ±12%. The rate of freedom from all complications at 10 years was 43±11% for the combined group and 70±8% for the mechanical group. We find no advantage in mixing aortic mechanical and mitral tissue valves when performing double valve replacement.

Myocardial infarction after partial left ventriculectomy

Background Clinical results of ATS prosthetic heart valve use in Japan have not been fully investigated. We analyzed the mid-term results of its use in a single center. Methods Among 88 patients, mean age 61.1±9.9 years, 32 had aortic valve replacement （AVR） , 42 mitral valve replacement （MVR） , and 14 both aortic and mitral valve replacement （DVR） . Mean follow-up was 2.5±1.5 years with a cumulative follow-up of 224.2 patientyears. Results There were 3 early deaths （3.4%: all in the MVR group） and 7 late deaths （1.8±1.7 %/ patient-year: 3 valve related and 4 valve unrelated） . Survival at 5 years was 96.8±17.8 % in the AVR group, 82.2±37.7 % in the MVR group, and 85.7±33.9 % in the DVR group. The linearized incidences of embolism （3） , bleeding events （2） , prosthetic valve endocarditis （3） , hemolysis （1） and re-operation （1） in all patients were 1.3±1.5 %, 1.9±1.9 %, 0.2±0.6 %, 2.1±1.8 % and 0.1±0.6 %/patient-year, respectively. No other complications were observed. Conclusion The ATS prosthetic heart valve showed excellent mid-term clinical results, with a low
