“…Recent studies have demonstrated the importance of collateral supply in IMR reduction [26]. Despite this, other studies have shown that collateral flow compensates for antegrade flow reduction and relieves ischaemia in stable coronary artery disease with chronic total occlusion in less than 5% of patients [27]. In our study, a large proportion of patients exhibited IMR despite well-developed collateral flow to occluded culprit artery region.…”

“…This has already been proven not true for all cases. In fact, there can be adjacent or distal myocardial areas with overlapping circulation in a considerable proportion of normal hearts (28)(29)(30)(31). Collateral arteries or arterioles extending beyond the vascular territorial borders (even to other main epicardial vessels) can exist.…”

Despite septal myectomy remaining the gold standard septal reduction therapy for hypertrophic obstructive cardiomyopathy (HOCM), there has been a disproportionate use of alcohol septal ablation (ASA) worldwide.Absolute resolution of left ventricular outflow tract (LVOT) obstruction with ASA is not achieved in a substantial proportion of patients. The mechanisms of failure from ASA are partially understood and described. Residual obstruction in hypertrophic cardiomyopathy is associated with worse clinical outcomes and mortality. There is a growing number of patients who present with significant residual gradients after ASA and require a rescue septal myectomy operation, which then carries an increased risk of perioperative complications and life-long sequelae. This contrasts with the excellent outcomes achieved by septal myectomy without previous percutaneous intervention. Despite complete resolution of obstruction in rescue myectomy, the outcomes remain compromised by the prior ASA.

“…In the human heart, the development of coronary collaterals serves as a conduit, bridging significantly stenotic or occluded coronary vessels, and constitutes a natural bypass system (Seiler, 2010;Traupe et al, 2010). Currently, routine coronary angiography reveals that about 20%-30% of patients with significant coronary artery disease had chronic total occlusion.…”

Abstract:Objective: Coronary collateral circulation is an alternative source of blood supply to myocardium in the presence of advanced coronary artery disease. We sought to determine which clinical and angiographic variables are associated with collateral development in patients with stable angina and chronic total coronary occlusion. Methods: Demographic variables, biochemical measurements, and angiographic findings were collected from 478 patients with stable angina and chronic total coronary occlusion. The presence and extent of collaterals supplying the distal aspect of a total coronary occlusion from the contra-lateral vessel were graded from 0 to 3 according to the Rentrop scoring system. Results: Low (Rentrop score of 0 or 1) and high (Rentrop score of 2 or 3) coronary collateralizations were detected in 186 and 292 patients, respectively. Despite similar age, cigarette smoking, and medical treatment, patients with low collateralization were female in a higher proportion and less hypertensive, and had higher rates of type 2 diabetes and dyslipidemia than those with high collateralization (for all comparisons, P<0.05). In addition, patients with low collateralization exhibited more single-vessel disease, less right coronary artery occlusion, more impaired renal function, and higher serum levels of high-sensitivity C-reactive protein (hsCRP) compared with those with high collateralization. Multivariate analysis revealed that age of ≥65 years, female gender, diabetes, no history of hypertension, dyslipidemia, moderate to severe renal dysfunction, single-vessel disease, and elevated hsCRP levels were independently associated with low coronary collateralization. Conclusions: Coronary collateralization was reduced in almost 40% of stable angina patients with chronic total occlusion, which was related to clinical and angiographic factors. The impact of coronary collateralization on outcomes after revascularization needs further investigation.
