The role of mantle and crust in the generation of calc-alkaline Variscan magmatism and its tectonic setting in the Eastern Pyrenees

The lower structural levels of the Variscan orogen exposed in the Eastern Pyrenees reveal three genetically associated magmatic suites: (i) a batholitic sized calc-alkaline granitoid (Sant Llorenç – La Jonquera, SL–LJ); (ii) minor mafic intrusions with local ultramafic cumulates (Ceret and Mas Claret mafic complexes); and (iii) peraluminous leucogranite bodies. These suites were emplaced in a syn- to post-collisional setting during the Late Carboniferous – Early Permian (ca. 315–290 Ma) in an Upper Proterozoic-Upper Ordovician metasedimentary sequence. We carried out field and petrographic work and whole-rock geochemistry (including Sr–Nd radiogenic isotopes) in order to constrain the petrogenetic relationships between them and to determine the interplay of the igneous suites with the country rock. We compare geochemical data to those from the neighbouring massifs of the Pyrenees and Catalan Coastal Ranges. The granitoids and the mafic complexes underwent variable degrees of lower crustal assimilation as demonstrated by the Sr and Nd isotopic ratios of SL–LJ granitoids and mafic rocks. Contaminated gabbro-diorites are high in Fe and Zr and contain magmatic garnet in equilibrium with an Fe–Mg amphibole. A supra-subduction metasomatized mantle source for the mafic complexes is inferred. The magma that formed the SL–LJ granitoids was of intermediate composition and may have formed by differentiation of of magmas derived from partial melting of a subduction-metasomatized mantle caused by active subduction or mantle delamination or by partial melting of the lower crust triggered by underplating of mantle-derived mafic magmas. Leucogranite magmas formed later by partial melting of crustal rocks with compositions similar to the outcropping metapelites and orthogneisses. We deduce a retrograde cooling decompression path from 0.75 GPa down to 0.55 GPa from phase equilibria for a garnet-bearing diorite. This path is compatible with a local extensional context linked to a regional dextral strike-slip regime that provided space for the ascent and emplacement of the pluton. This strike-slip system is consistent with late-Variscan shear zones displacing Gondwana to the west with respect to Laurasia during the orogenic collapse.This work was benefited from the Spanish Commission for Science and Technology research projects CGL2015-66335-C2-2-R, PGC2018-096534-B-I00 (IBERCRUST) and PGC2018-093903-B-C22.

Transcatheter valve-in-valve implantation versus redo surgical aortic valve replacement in patients with failed aortic bioprostheses

OBJECTIVES: Transcatheter aortic valve-in-valve implantation (ViV) is a new treatment for failing bioprostheses (BP) in patients with high surgical risk. However, comparative data, using standard repeat surgical aortic valve replacement (redo-SAVR), are scarce. We compared outcomes after ViV with those after conventional redo-SAVR in two European centres with established interventional programmes. METHODS: In-hospital databases were retrospectively screened for patients ?60 years, treated for failing aortic BP. Cases of infective endocarditis or combined procedures were excluded. End-points were adjudicated according to the Valve Academic Research Consortium (VARC-2) criteria. RESULTS: From 2002 to 2015, 130 patients were treated (ViV: n = 71, redo-SAVR: n = 59). Age and logistic EuroSCORE I scores were higher with ViV (78.6 7.5 vs 72.9 6.6 years, P 0.01; 25.1 18.9 vs 16.8 9.3%, P 0.01). The 30-day mortality rate was not significantly different (4.2 and 5.1%, respectively) (P = 1.0). Device success was achieved in 52.1% (ViV) and 91.5% (P 0.01). No stroke was observed after ViV but in 3.4% after redo-SAVR (P = 0.2). Intensive care stay was longer after redo-SAVR (3.4 2.9 vs 2.0 1.8 days, P 0.01). Mean transvalvular gradients were higher post-ViV (19.7 7.7 vs12.2 5.7 mmHg, P 0.01), whereas the rate of permanent pacemaker implantation was lower (9.9 vs 25.4%, P 0.01). Survival rates at 90 and180 days were 94.2 and 92.3% vs 92.8 and 92.8% (P = 0.87), respectively. CONCLUSIONS: Despite a higher risk profile in the ViV group, early mortality rates were not different compared with those of surgery. Although ViV resulted in elevated transvalvular gradients and therefore a lower rate of device success, mortality rates were similar to those with redo-SAVR. At present, both techniques serve as complementary approaches, and allow individualized patient care with excellent outcomes.</p
