Management strategies in patients affected by chronic total occlusions: results from the Italian Registry of Chronic Total Occlusions
2015
Background Through contemporary literature, the optimal strategy to manage coronary chronic total occlusions (CTOs) remains under debate. Objectives The aim of the Italian Registry of Chronic Total Occlusions (IRCTO) was to provide data on prevalence, characteristics, and outcome of CTO patients according to the management strategy. Methods The IRCTO is a prospective real world multicentre registry enrolling patients showing at least one CTO. Clinical and angiographic data were collected independently from the therapeutic strategy [optimal medical therapy (MT), percutaneous coronary intervention (PCI), or coronary artery bypass grafting (CABG)]; a comparative 1-year clinical followup was pe…
Emergency angioplasty of totally occluded left main coronary artery in acute myocardial infarction and unstable angina pectoris--institutional experi…
1994
Acute occlusion of the left main coronary artery (LMCA) is a rare angiographic finding. We report five patients with acute myocardial infarction (AMI) and one patient with unstable angina, in whom reperfusion was achieved or attempted with percutaneous transluminal coronary angioplasty (PTCA). All patients had a long history of stable angina pectoris. The indication for emergency PTCA was cardiogenic shock in the five patients with MI. PTCA was successful in five of six patients. Three patients with reperfusion survived, three died. All survivors underwent coronary artery bypass grafting (CABG) and were still alive at 23 months, 3 and 8 years respectively in NYHA functional class II or III.…
Long-term outcomes of percutaneous coronary interventions or coronary artery bypass grafting for left main coronary artery disease in octogenarians (…
2014
Percutaneous coronary intervention (PCI) with drug-eluting stents is an accepted alternative to surgery for the treatment of unprotected left main coronary artery (ULMCA) disease, but the long-term outcome in elderly patients is unclear. Aim of our study was to compare the clinical outcomes of octogenarians with ULMCA disease treated either with PCI with drug-eluting stents or coronary artery bypass grafting (CABG). The primary study end point was the composite of death, cerebrovascular accident, and myocardial infarction at follow-up. A total of 304 consecutive patients with ULMCA stenosis treated with PCI or CABG and aged 80 years were selected and analyzed in a large multinational regist…
Automated Weaning from Mechanical Ventilation after Off-Pump Coronary Artery Bypass Grafting
2017
Background The discontinuation of mechanical ventilation after coronary surgery may prolong and significantly increase the load on intensive care unit personnel. We hypothesized that automated mode using INTELLiVENT-ASV can decrease duration of postoperative mechanical ventilation, reduce workload on medical staff, and provide safe ventilation after off-pump coronary artery bypass grafting (OPCAB). The primary endpoint of our study was to assess the duration of postoperative mechanical ventilation during different modes of weaning from respiratory support (RS) after OPCAB. The secondary endpoint was to assess safety of the automated weaning mode and the number of manual interventions to the…
Expression of the proto-oncogene c-myc in human stenotic aortocoronary bypass grafts.
2002
Summary Proliferation and differentiation of vascular smooth muscle cells (VSMC) are central events in vascular pathobiology and play a major role in the development of stenotic and restenotic lesions [ 15, 27 ] . The proto-oncogene c-myc and other early cell cycle-regulating genes have been implicated in the induction of cell proliferation and differentiation under diverse pathophysiological conditions [ 11, 13 ] . In the present study we analyzed c-myc mRNAexpression by indirect nonradioactive in situ hybridization technique (NISH) in human stenotic venous bypass grafts (n = 32) retrieved during re-do operations of coronary artery disease and compared the results with 28 native veins (ven…
PTCA of the left main stem following protective coronary artery bypass grafting.
1991
Percutaneous transluminal coronary angioplasty (PTCA) was performed in 14 patients with significant left main stem stenosis following protective coronary artery bypass grafting (CABG). The procedure was successful in 13/14 patients (93%), achieving a decrease in mean diameter stenosis from 74% +/- 7% to 31% +/- 12% (P less than 0.01). Accordingly, the absolute stenosis diameter increased from 0.9 mm +/- 0.3 mm to 2.4 mm +/- 0.5 mm (P less than 0.01). Dissection of the left main stem artery and a transient significant fall of blood pressure each occurred in one patient. No other serious complications were noted. Eight of 13 patients (62%) with successful PTCA underwent control angiography. R…
‘Soft’ Snaring of the Coronary Artery in Minimally-Invasive Coronary Surgery
1998
A technique is described that allows a simple and safe temporary occlusion of the coronary artery in beating heart procedures using monofilament stay sutures underlaid with small pericardial pads. Postoperative serial levels of Troponin I remained low (<4 ng/L) and control angiography revealed no stenosis in the distal coronary artery.
Evidence for a negative inotropic effect of obesity in human myocardium?
2009
Objective: The present study was performed as an attempt to analyze the relationship between body weight and human myocardial performance. As overweight is frequently associated with hypertension, stenosis of epimyocardial coronary arteries and other factors that influence myocardial performance, the experimental model of isolated human atrial myocardium was selected. Atrial contractile performance does neither depend on the extent of stenosis of epicardial coronary arteries nor on the degree of hypertension and its secondary pathology. Methods:Rightatrialmusclepreparations(0.5 6 mm)of183patientsundergoingcoronaryarterybypasssurgerywereelectricallystimulatedat optimal length. Active tension…
Training Cardiac Surgeons: Safety and Requirements.
2021
To analyze whether cardiac surgical residents can perform their first surgeries without compromising patients' safety or outcomes, by comparing their performance and results to those of senior surgeons. All documented CABGs conducted between 2002 and 2020 were included. Surgeries were divided according to the experience level of the main surgeon (defined by the number of CABG conducted by him/her) using the following thresholds: 1000; 150; 80 and 35. This resulted in 5 groups: senior surgeons (the reference group); attending surgeons; fellow surgeons; advanced residents and new residents. Primary endpoint was 30 day mortality. Secondary endpoints included a list of intra and post-operative …
