Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...

BACKGROUND Because of limited surgical field, minimally invasive coronary artery bypass grafting (MIDCAB) requires anastomosis to the distal portion of the left anterior descending artery (LAD) of the left internal thoracic artery (LITA) with the heart beating. Though the diameters of these arteries are very small, it is unknown whether blood flow sufficient for the LAD territory is obtained by...

A 69-year-old man without cardiovascular risk factors was admitted to our hospital with unstable angina. After 48 hours he underwent coronary angiography, showing severe disease of mid left anterior descending (LAD) coronary artery and proximal segment of the first diagonal (DX) (Figure 1A). Balloon predilation was performed in LAD and 2 bioresorbable everolimus-eluting (3 28 mm and 3.5 28 mm) ...

OBJECTIVES We studied left atrial volume (LAV) as an index of atrial size. BACKGROUND Increased left atrial dimension (LAD) measured by M-mode echocardiography is a risk factor for atrial fibrillation, stroke, and death. METHODS A random sample of residents of Olmsted County, Minnesota, age 45 years (n 2,042) underwent Doppler echocardiography with assessment of LAD and LAV. A subgroup of the p...

Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...

BACKGROUND Incorporation of analysis of coronary velocities in stress studies adds diagnostic value to both clinical variables and dobutamine echocardiography. Micorcirculatory abnormalities may precede obstructive corornary disease. Therefore the aim of this study was to assess Doppler derived coronary velocity and flow of the left anterior descending coronary artery (LAD) during dobutamine st...

Virtually all cardiac surgeons and their referring cardiologists know that the most effective and reliable coronary artery bypass conduit is the pedicled internal thoracic (mammary) artery (LITA) when placed to the left anterior descending artery coronary artery (LAD). This first choice of bypass graft conduits is based on convincing evidence of improved survival in patients with critical LAD d...

BACKGROUND AND PURPOSE The pathogenesis of deep white matter medullary (WMM) artery infarcts remains controversial. To address this question, we analysed the stroke patterns of WMM infarcts using diffusion weighted magnetic resonance imaging (DWI) to detect embolic signals and investigate stroke subtypes according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classifications. ME...

In order to evaluate the ability of the echocardiogram to detect and localize left main or left anterior descending (LAD) coronary artery lesions, 43 patients were studied. The systolic excursion of the left side of the septum and the ratio of posterior wall to septal excursion were measured. Seventeen patients had no LAD lesions; all had systolic septal excursion of 3 mm or greater. Twelve pat...
