Although there are 4 approved bioresorbable scaffolds (BRS) in Europe, experts suggest that current drug-eluting stents (DES) are the best option for coronary angioplasty. These new guidelines jointly published by the European Society of Cardiology (ESC) and the Association of Percutaneous Cardiovascular Interventions (EAPCI) are an update on the use of BRS in clinical practice...
Courtesy of Dr. Carlos Fava. The incidence of unprotected left main severe stenosis ranges between 4 and 8%, and it’s mostly associated with multivessel disease. The use of left ventricular support devices in high risk unprotected left main PCI is on the rise, but not much information available in this regard. Read also: “Prior assistance...
Courtesy of Dr. Carlos Fava. Coronary perforation (CP) is a very uncommon event (≈0.4%), associated with severe complications that entail risk of death. It has usually been related to patients with a history of myocardial revascularization surgery (MRS). However, this group usually presents lower rates of cardiac tamponade due to pericardial fibrosis caused by surgery. This...
Diabetes mellitus patients generally present more diffuse coronary disease, faster lesion progression and higher risk of restenosis after PCI. The way these anatomical differences translate into in a different clinical practice, compared to non-diabetic patients, remains unclear. Prior studies comparing the frequency of angina symptoms in diabetic vs. non-diabetic patients have arrived to contradicting outcomes,...
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...
Overnight observation after coronary angioplasty has been the standard of care in the United States. The foundations for this practice go back to the early days of balloon angioplasty, when acute occlusion and access-site complications were frequent. There are several registries and randomized studies showing the clear safety of same-day discharge after coronary angioplasty. This practice...
According to a recent study published in Circulation Cardiovascular Interventions, screening for coronary artery disease (CAD) with an invasive coronary angiography (as part of the protocol prior TAVR) and performing PCI and TAVR in the same session, has no impact on periprocedural safety or on long term outcomes. Study outcomes offer new hope, especially as regards using TAVR...
Courtesy of Dr. Cristian Jesús Rodríguez. Most stents currently used in percutaneous coronary intervention (PCI) are durable-polymer second-generation drug-eluting stents (DP-DES, with everolimus or zotarolimus). However, it has been argued that the persistence of such a polymer after complete drug elution is one of the main factors for a dangerous complication: stent thrombosis (ST). After...
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,...
