Percutaneous transluminal angioplasty of coronary arteries with anomalous origin

Abstract

Coronary angioplasty to diseased anomalous coronary arteries is being more readily applied in revascularization of these vessels. Several cases of angioplasty have been described in various coronary anomalies. Probably more attempts of PTCA to anomalous coronary arteries are performed but not reported. For this reason, we cannot assume that the success rate is the same as in "normal" origin arteries or which complications occurred, including the need for coronary bypass. Although not yet reported, in some instances other techniques, such as laser atherectomy and coronary stents, may be applied, provided the artery is not tortuous, as it may be in some anomalous coronaries. The key to a successful procedure depends on angiographic knowledge of their course and appropriate equipment selection.

Percutaneous coronary intervention with stent deployment in anomalously‐arising left circumflex coronary arteries

“…Previous authors have described similar interventions, albeit most commonly in the pre‐stent era [14, 16–18]. Successful PCI to anomalously‐arising vessels depends on stability and coaxial positioning of the guiding catheter to aid wire and balloon/stent catheter passage into these tortuous arteries; the choice of guiding catheters in our series fits well with previously published reports [13–18, 22–24], see Table II). For type II or III anomalous circumflex ostia, we used Judkins or Amplatz right guiding catheters successfully to selectively intubate the anomalous vessel; the use of a double‐wire technique [19], as utilized in three of our cases, may enhance catheter stability further.…”

“…Percutaneous coronary intervention (PCI) to anomalous coronary arteries poses certain technical difficulties, not least in selection of suitable guiding catheters for optimum stability during such procedures [13–17]. Seven cases of PCI with stent deployment to anomalous left circumflex vessels have been published as isolated reports [13, 18]; this single‐center study examines a larger series of patients undergoing PCI with stent deployment to anomalous left circumflex coronary arteries, with particular reference to technical aspects of the PCI procedure itself, to the anatomy of the anomalous coronary, and to the degree of atherosclerotic disease burden.…”

Effect of Hospital Volume on Outcomes of Transcatheter Mitral Valve Repair: An Early US Experience

“…The NIS is the largest publicly available all‐payer inpatient care database in the US, and includes data on approximately 7–8 million discharges per year. It is a stratified 20% sample of discharges from US community hospitals, excluding rehabilitation and long‐term acute care hospitals . National estimates are produced using sampling weights provided by the sponsor.…”

“…National estimates are produced using sampling weights provided by the sponsor. Details regarding the NIS data have been previously published . Annual data quality assessments of the NIS are performed, to maintain the internal validity of the database.…”

Successful percutaneous coronary angioplasty in a patient with anomalous origin of the right coronary artery from the left anterior descending artery

“…In literature there has been many different successful PTCA and stenting for different coronary artery anomalous [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Our case differentiated for being the proximal lesion of LAD with RCA which basis on diagonal and successful expansion resulted.…”
