The presence of coronary artery disease (CAD) in patients with aortic stenosis is high, reaching 50% to70% of cases. This poses a great challenge as to what strategy to use and the things we can do. Even though it has been shown complete revascularization is beneficial, it is often difficult to achieve. Instead, reasonable incomplete...
A new study raises an alarm against expanding transcatheter aortic valve replacement (TAVR) procedures to low surgical risk patients, since 2 year mortality seems higher in these patients with TAVR, compared to conventional surgery. This study will soon be published in Catheter Cardiovasc Interv. Expanding TAVR to low risk patients might involve risks we have not...
St elevation acute coronary syndromes are typically caused by thrombotic obstruction of a coronary artery due to ruptured atherosclerosis plaque. However, there is a significant number of patients with similar clinical presentations but no evidence of obstructive coronary artery disease (CAD). Read also: CTO in patients with acute myocardial infarction increases long term mortality. In general, patients without...
Patients undergoing primary angioplasty for ST-segment elevation acute myocardial infarction have similar clinical outcomes at 1 year regardless of whether they are treated with ticagrelor or prasugrel, according the PRAGUE-18 study. This new substudy adds an interesting detail: patients who switched from prasugrel and ticagrelor to clopidogrel, citing economic reasons for the “de-escalation” of therapy, were...
Use of IV bicarbonate instead of saline and administration of oral N-acetylcysteine are not effective strategies for preventing contrast-associated acute kidney injury in patients with chronic kidney disease undergoing angiography, according to the randomized PRESERVE trial that was presented at the AHA 2017 Scientific Sessions and published simultaneously in the New England Journal of Medicine...
About 25% of patients with multivessel disease undergoing myocardial revascularization surgery or PCI have diabetes. In this subgroup, the benefit of surgery in terms of mortality has long been shown: in the BARI study (Bypass Angioplasty Revascularization Investigation) patients undergoing PCI had close to double the mortality rate at 5 years compared to those...
The SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) trial, which included patients with 3-vessel or left main coronary artery lesions, showed that myocardial revascularization surgery (MRS) turned out to be superior to angioplasty with drug-eluting stents (DES), mainly due to differences in acute myocardial infarction and repeat revascularization. Up to this work, patient sensations (which can be...
Although chronic total occlusion (CTO) is a common finding, there is little consensus as to when such lesions should be treated routinely with angioplasty. Benefits of successful rechanneling include relief of symptoms, resolution of ischemia, improvement in ventricular function, and avoidance of myocardial revascularization surgery. Unsuccessful rechanneling is common and may be associated with several adverse events,...
Courtesy of Dr. Carlos Fava. Repairing the mitral valve with Mitraclip has become an alternative for high risk or inoperable symptomatic patients, but its long term evolution has only been tested by the EVEREST II, which had not taken into account 5 year mortality outcomes. Therefore, to better study its evolution, we need to carry out different randomized studies...
Courtesy of Dr. Carlos Fava. The presence of paravalvular leaks (PVL) after aortic valve replacement ranges between 5% and 20%. Percutaneous repair has emerged as a feasible alternative, effective and safe, to prevent new surgery. The study included 86 patients undergoing aortic valve replacement presenting PVL with cardiac failure CFIII or IV and/or anemia....
