Telomere shortening in arteries could lead to telomere uncapping and cellular senescence, which in turn could promote the development of hypertension. To assess the novel role of arterial telomere dysfunction in hypertension, we compared mean telomere length (qPCR), telomere uncapping (serine 139 phosphorylated histone γ-H2A.X (γ-H2) localized to telomeres: ChIP), ...

This article puts forward a modified technique of Konno aortoventriculoplasty for repeat procedures. After incision of the ventricular septum, this approach involves aortic valve replacement using a mechanical valved conduit, reimplantation of the coronary arteries, and graft replacement of the ascending aorta. This modification allows the removal of the diseased ...

Because stent underdeployment occurs frequently, accurate minimal stent area (MSA) measurement during postdilatation is necessary. This study investigated the accuracy and repeatability for MSA determination using a novel conductance balloon (CB) catheter for peripheral vessels. The CB catheter is a standard balloon catheter that measures electrical conductance (ratio of current/voltage ...

We report the successful management of underexpansion of a newly deployed coronary stent refractory to balloon dilatations. Direct stenting was performed for a lesion in the mid left anterior descending artery (without angiographically apparent heavy coronary calcification). The stent remained underexpanded despite repeated balloon dilatations including with high-pressure inflations. Subsequently, ...

We described a case of angiographic stenosis that was highly suitable for stenting and it remained even after repeated intracoronary administration of nitroglycerin. However, optical coherence tomography showed the stenosis disappeared and the artery wall was smooth. It was therefore speculated that this was a just non-spasm pseudo-coronary artery stenosis. ...

The advent of drug-eluting stents (DES) associated with improvements in interventional techniques, encouraged the use of percutaneous coronary intervention (PCI) for unprotected left main (ULM) stenosis because of the lower need of repeat revascularization compared to the bare-metal stents (BMS). Nevertheless, ULM DES in-stent restenosis (ISR) continues to occur. The ...

Rationale- Hypoxic pulmonary hypertension is a worldwide public health problem. Statins attenuate hypoxic pulmonary hypertension in animal models but the mechanism of action and applicability of these results to human treatment is not established. In hypoxic models, pulmonary artery fibroblast proliferation contributes substantially to pulmonary vascular remodelling. We have previously ...
