with midsternotomy, and after evaluating the LAD, unroofing of LAD was done, 16 patients underwent this procedure with the aid of cardiopulmonary bypass (CPB), with pump time of average 38.8 ± 4.3 minutes and clamp time of average 23.2 ± 1.6 minutes. With a Potts scissors the muscle bridge overlying the LAD was divided. During division of

Methods: Adult patients (n=101) who underwent LAD MB unroofing at our institution between 11/2011-12/2018 were included. MBs were characterized by coronary angiography and intravascular ultrasonography. Hemodynamic significance was determined by diastolic fractional flow reserve (dFFR) measured distal to the MB.

One patient had an off-pump operation, whereas in 34 cardiopulmonary bypass (CPB) was used with aortic cross-clamping and cardioplegic arrest. The operation began with identification of the LAD coronary artery beyond the intramyocardial portion. Background: Myocardial bridge (MB) of the left anterior descending (LAD) coronary artery occurs in approximately 25% of the population. For patients with a symptomatic, hemodynamically significant MB who fail medical therapy, MB unroofing represents the optimal surgical management. The currently favored approach for repair is the anatomic correction by an unroofing procedure, that results in relocation of the coronary artery into the appropriate aortic sinus and is demonstrated in the following video. This approach can be carried out with minimal risk, good anatomical and functional results.

The CT nicely shows the neo ostium after surgery Cardiac catheterization via a radial approach demonstrated minimal non-obstructive coronary artery disease, with a bridging effect in the mid LAD (Figures 1-2, Video 1). Optimizing medical management was the course of treatment.

This video demonstrates the unroofing of a left anterior descending coronary artery myocardial bridge combined with right ventricular septal myectomy in a pa

Dense adhe-sions made it difficult to localize the distal LAD. Once local- When symptoms are recalcitrant to medical therapy, unroofing (myotomy) is the preferred surgical treatment strategy in the absence of concomitant obstructive CAD in the LAD. 33 We regard percutaneous stent placement for treatment of MB‐associated symptoms as relatively contraindicated, given the potential risk of stent fracture from unabated compression 34-37 and increased risk of … Methods: Adult patients (n=101) who underwent LAD MB unroofing at our institution between 11/2011-12/2018 were included.

1 This congenital coronary anomaly results in systolic compression of the tunneled portion of the coronary artery and remains clinically silent in the majority of cases.

Over the years, the most favored and physiologically efficient method is the so called LAD-unroofing (or de-roofing) procedure, whereby the muscle covering the LAD is dissected, hence removing the “squeeze” around the vessel during systole. The currently favored approach for repair is the anatomic correction by an unroofing procedure, that results in relocation of the coronary artery into the appropriate aortic sinus and is demonstrated in the following video. This approach can be carried out with minimal risk, good anatomical and functional results. Background: There is a paucity of data regarding results of surgical management of myocardial bridging.

We became aware of MBs as a potential etiology of chest pain in the pediatric population in 2012. Between September 2012 and December 2016, 14 pediatric patients younger than 21 years of age, with isolated, symptomatic, and hemodynamically significant LAD MBs underwent surgical unroofing of LAD MBs.

MBs were characterized by A myocardial bridge (MB) is a congenital heart defect in which one of the coronary arteries Unroofing surgery today is done via open heart (sternum), thoracotomy (through the ribs), and also using The largest autopsy report, whic whom a long segment of left anterior descending (LAD) artery bridging was discovered on extensive of a defibrillator and surgical unroofing of the LAD bridge. 2020年12月14日 Here, we evaluated minimally invasive MB unroofing in selected patients Myocardial bridge (MB) of the left anterior descending (LAD) coronary artery marsupialization or "unroofing" - opening the intramural portion of the left circumflex or LAD artery arising from the right coronary sinus. LAD indicates left anterior descending artery; Cx, circumflex artery; RCA, right and unreliable approach); (2) unroofing of the intramural coronary segment, 2 Jul 2020 anterior descending artery (LAD). Initially, he was trialed on maximal medical therapy, however, symptoms continued.
