Calcium score association with paravalvular leakage in patients who underwent TAVR, the Mexican values.

Objective: The objective is to determinate the association between the degree of aortic valve calcification and the presence of paravalvular leakage (PVL) in Mexican patients who underwent transcatheter aortic valve replacement (TAVR).

Methods: We conducted a retrospective, analytic, cohort. Pooled data were retrospectively analyzed from the patient's files from January 2014 to July 2022.

Early stenosis in a Gore-Tex graft connected to the left main: an emergency transradial angioplasty for a complication in a Cabrol procedure.

This is a case report of a successful transradial percutaneous intervention in a stenosis in a Cabrol graft. Very few reports have been published about percutaneous interventional solutions to complications in this kind of graft, and none have used the transradial approach. The Cabrol technique is used to re-implant coronary arteries after aortic root replacement using a Dacron or Gore-Tex graft interposed between the aortic root graft and the native coronary artery.

Design and implementation of the TRACIA: intracoronary autologous transplant of bone marrow-derived stem cells for acute ST elevation myocardial infarction.

Objective: To describe the design of a protocol of intracoronary autologous transplant of bone marrow-derived stem cells for acute ST-elevation myocardial infarction (STEMI) and to report the safety of the procedure in the first patients included.

Methods: The TRACIA study was implemented following predetermined inclusion and exclusion criteria. The protocol includes procedures such as randomization, bone marrow retrieval, stem cells processing, intracoronary infusion of stem cells in the infarct-related artery, preand- post MRI, pre-and-post SPECT with radioisotope ventriculography, and clinical follow-up at 6 months.
