Ponte miocárdica: evolução clínica e terapêutica

Abstract

Background: The myocardial bridge constitutes one of the main differential diagnoses of coronary artery disease. However, it remains an underdiagnosed condition and its physiopathological mechanisms and therapeutics are yet to be elucidated.

Myocardial Muscle Bridge: An Unusal Cause of Acute Myocrdial Infarction

“…14 Surgical interventions are reserved for patients with angina that is refractor y to dr ug treatment. 15 Improvement in symptoms has been shown with stenting of the bridged segment. However, requirement of h ig h in flat io n press ures f or o pt imal s tent implanta tion brings ou t the risk of coronar y perforation.…”

Morphological Changes Associated with Hemodynamically Significant Myocardial Bridges in Sudden Cardiac Death

“…Surgical intervention, nowadays used only if stenting is contraindicated (long bridges, severe proximal atherosclerosis with calcifications, restenosis, etc. ), is done, using mainly one of two methods: myomectomy and myocardial revascularization surgery, with an anastomosis between the internal mammary artery and the LAD [57]. However, SCD associated with MB often occurs in previously asymptomatic patients, as revealed by our discussions with families.…”

Computed tomography angiography of the coronary arteries: major findings in the clinical routine of a general hospital

“…Among the secondary findings reported were an As previously noted, myocardial bridging in the ADA was the third most common finding in our sample. It is known that myocardial bridging is a congenital anomaly in which the myocardium crosses over or envelops a segment of an epicardial artery and may manifest as angina pectoris (6) , which is one of the main differential diagnoses of CAD. The area below a myocardial bridge is spared from atherosclerotic disease, whereas the proximal area presents a risk of CAD development, which is extremely important in the clinical context of this study.…”
