Most acute coronary syndromes (ACS) are caused by the following three different pathologies: Plaque rupture Plaque erosion Calcified nodule In daily clinical practice, all patients who experience them are treated with angioplasty, regardless of which of these physiopathologies led to the ACS in each case. Some early reports indicate that patients with plaque erosion might...
Courtesy of Dr. Carlos Fava. In most randomized or observational studies, women comprise more than 50% of patients undergoing TAVR, and they have showed better evolution, compared against surgery. The main differences between men and women with severe aortic stenosis are that women have smaller annular dimension, shorter distance to coronary ostia, smaller peripheral arteries, and...
1) New High Blood Pressure Guidelines The wait is finally over: the high blood pressure guidelines that have been in the works for the past 3 years saw the light of day at the American Heart Association (AHA) 2017 Scientific Sessions.

The presence of inducible ischemia is an essential prerequisite to obtain clinical benefits from revascularization through angioplasty. In that sense, the measurement of fractional flow reserve (FFR) is the gold standard as regards invasive methods assessing the functional significance of epicardial artery stenosis. As opposed to FFR, the measurement of the instantaneous wave-free ratio (iFR)...
Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are commonly used to assess physiological severity of angiographically intermediate stenosis. Both indexes quantify a pressure ratio as subrogate to measuring flow, which is much harder to do. Discordance between FFR and iFR occurs in up to 20% of cases, which should not be a matter...

I am pleased to witness the increased amount of scientific papers in high impact journals addressing topics related to radiation protection or the harmful effects of radiation on our patients and primary or secondary operators. Similarly, it is my pleasure to see that SOLACI has acknowledged this growing concern by...
The occurrence of renal failure after any endovascular intervention is associated with increased morbility and mortality. After a coronary intervention (whether it be angioplasty or surgery), renal failure increases mortality 20-fold. Relatedly, surgical repair of an abdominal aortic aneurysm with renal failure is also associated with a significant increase in the number of events. Read...
Courtesy of Dr. Alejandro Lakowsky, MTSAC. The Journal of the American College of Cardiology (JACC) has recently published a study on the role of coronary anatomy and PCI technical difficulty in the cost benefit ratio of prolonged vs. short post procedural DAPT. This study was carried out by Robert Yeh, Laura Mauri and the DAPT trial...
Previous studies in which revascularization was guided by angiography alone found that coronary angioplasty does not improve outcomes compared with optimal medical treatment in patients with chronic stable angina. The FAME 2 trial (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation) compared angioplasty guided by fractional flow reserve (FFR) with optimal medical treatment, arriving to...
In the US, more than 4 million patients with chronic stable angina are looking to rule out heart disease. Most undergo functional diagnostic studies that might lead to invasive coronary angiography followed by revascularization. CT has become an alternative diagnostic tool thanks to its precision to rule out heart disease (negative predictive value between 97...
