We demonstrate that congestive HF programmes should consider offering PD in hope of seeing better functional status, reduced morbidity and mortality, better quality of life as well as reduced health care costs.

The Spanish Post-Heart-Transplant Tumour Registry comprises data on neoplasia following heart transplantation (HT) for all Spanish HT patients (1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003). This retrospective analysis of 3393 patients investigated the incidence and prognosis of neoplasia, and the influence of antiviral prophylaxis. About 50% of post-HT neoplasias were cutaneous, and 10% lymphomas. The cumulative incidence of skin cancers and other nonlymphoma cancers increased with age at HT and with time post-HT (from respectively 5.2 and 8.9 per 1000 person-years in the first year to 14.8 and 12.6 after 10 years), and was greater among men than women. None of these trends held for lymphomas. Induction therapy other than with IL2R-blockers generally increased the risk of neoplasia except when acyclovir was administered prophylactically during the first 3 months post-HT; prophylactic acyclovir halved the risk of lymphoma, regardless of other therapies. Institution of MMF during the first 3 months post-HT reduced the incidence of skin cancer independently of the effects of sex, age group, pre-HT smoking, use of tacrolimus in the first 3 months, induction treatment and antiviral treatment. Five-year survival rates after first tumor diagnosis were 74% for skin cancer, 20% for lymphoma and 32% for other tumors.

The role of MICA antibodies in acute heart allograft rejection was examined utilizing 190 pre-and posttransplant serum samples from 44 patients collected during the first year after transplantation. MICA antibodies were detected by CDC test on recombinant cell lines and by the newly developed Luminex MICA antibody detection assay. Additionally, MICA expression was analyzed by 'real time' RT-PCR and by immunohistochemistry in 10 endomyocardial biopsies. Only two subjects had HLA antibodies post-transplant. Nevertheless, MICA antibodies were found in a significant number of subjects. The prevalence of MICA antibodies was significantly higher among those with severe acute rejection (AR) than in those without rejection (60.7% vs. 14.3%, p = 0.0038 by CDC; 55.5% vs. 5.7%, p = 0.0020 by Luminex). In most cases, the appearance of MICA antibodies post-transplant precedes AR. Following transplantation, MICA up-regulation correlated with histological evidence of severe rejection. Monitoring for MICA antibodies post-transplant may be useful to establish new risk factors for acute rejection.

CoreValve implantation worsens AV conduction in most patients, either transiently or permanently. This worsening is the result of direct damage either on the His bundle or on the AV node.

We provide a compelling evidence of the involvement of in the development of HCM. Most of the variants were associated with mild forms of HCM and a reduced penetrance, with few affected in the families to confirm the segregation. Our work, together with others who found variants among patients with dilated and restrictive cardiomyopathies, pointed to this gene as an important cause of structural cardiomyopathies.

Background: Mutations in the cardiac ␤-myosin heavy chain (MYH7) and cardiac troponin T (TNNT2) genes are reportedly responsible for up to 40% of familial cases with hypertrophic cardiomyopathy (HC). Although there are no mutational hotspots, most of the mutations are located in specific exons of the MYH7 and TNNT2 genes. Currently it is not possible to predict the phenotype in carriers of mutations in these genes, although it is widely accepted that mutations in the MYH7 gene predispose to severe HC, whereas TNNT2 mutations are frequently linked to sudden cardiac death (SCD) in spite of minimal hypertrophy. Methods: We sequenced exons 8, 9, 13-16, 19, 20, 22-24, and 30 of the MYH7 gene and exons 8, 9, 11, and 14 -16 of the TNNT2 gene in 30 HC patients (18 -60 years of age) from the region of Asturias (Northern Spain); 25 cases (80%) had a family history of the disease. Genomic DNA was amplified, and fragments were directly sequenced. Each DNA variant found in the patients was also analyzed in 200 healthy controls through single-strand conformation analysis. Results: Four of the probands had nucleotide changes absent in the healthy controls. Two cases had mutations previously described in the MYH7 gene (exon 14, Arg453Cys) or the TNNT2 gene (exon 16, Arg278Cys). Two cases had new mutations (MYH7 exon 22, Met822Val;

SummaryThe results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 AE 4.1 vs. 24.3 AE 3.7; P < 0.01), and male donors were younger than female donors (33.4 AE 12.7 vs. 38.2 AE 12.3; P < 0.01). No further relevant differences related to donor sex were detected. In the univariate analysis, mismatch was associated with mortality in men (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.06-1.32; P = 0.003) but not in women (HR, 0.91; 95% CI 0.74-1.12; P = 0.4). A significant interaction was detected between sex mismatch and recipient gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with longterm mortality (HR, 1.14; 95% CI 1.01-1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women.
