Impact of Mitral Annular Calcium and Mitral Stenosis on Outcomes After Transcatheter Aortic Valve Implantation.

Mitral annular calcium (MAC) is a common finding in patients undergoing transcatheter aortic valve implantation (TAVI) and may be associated with mitral stenosis (MAC-MS). Their impact on post-TAVI outcomes remains controversial. We sought to assess the impact of MAC and MAC-MS on clinical outcomes following TAVI.

[Fenestration of a spontaneous coronary hematoma with life-threatening dissection: A case of recurrent and multivessel spontaneous coronary artery dissections in a young female].

The fenestration of a coronary artery hematoma is a therapeutic option in case of a life-threatening spontaneous coronary artery dissection, if the conservative treatment is not feasible. Here we present the case of a 34-year-old woman who presented three spontaneous coronary artery dissections, on three different arteries, over a period of twenty-one months. The diagnosis was confirmed by endovascular imaging.

[ST-elevation myocardial infarction (STEMI) in the elderly].

Admission in cardiology departments of patients over 80 years old, even nonagenarians, for ST-segment elevation myocardial infarction (STEMI) is not uncommon in 2018. The management of these high risk and polypathological patients, with atypical clinical presentation, is not based on international guidelines or randomized studies, but rather on retrospective studies, expert consensus, and common sense. Each decision has to be individualized to the patient's situation.

Causes and temporal trends in procedural deaths after transcatheter aortic valve implantation.

Background: The causes of procedural deaths after transcatheter aortic valve implantation (TAVI) have been scarcely detailed.

Aims: To assess these causes and their temporal trends since the beginning of the TAVI era.

Methods: From October 2006 to April 2014, 601 consecutive high-risk/inoperable patients with severe aortic stenosis underwent TAVI using the Edwards SAPIEN or SAPIEN XT or the Medtronic CoreValve.

Peristrut microhemorrhages: a possible cause of in-stent neoatherosclerosis?

Background: In-stent neoatherosclerosis is characterized by the delayed appearance of markers of atheroma in the subintima, but the pathophysiology underlying this new disease entity remains unclear.

Methods And Results: We collected 20 human coronary artery stents by removal from explanted hearts. The mean duration of stent implantation was 34 months.
