Coronary Artery Bypass Grafting (CABG) versus Percutaneous Coronary Intervention (PCI) in treatment of left main coronary artery disease

BackgroundCoronary artery bypass graft surgery (CABG) has been widely used for left main coronary artery disease (LMCAD). Percutaneous coronary intervention (PCI) has become an option for this condition.AimsTo summarize the current evidence that compare between CABG vs. PCI in regards to ‎cardiac death, stroke, and myocardial infarction.‎Methods We searched randomized trials of treatment of LMCAD with PubMed, Google Scholar, and EBSCO.Results Five randomized studies were retrieved, which compared the efficacy between CABG vs. PCI in treatment of LMCAD.ConclusionPCI may be reasonable management of patients with LM stenosis involving distal bifurcation or with coexisting multivessel disease

Abductor tendon tears are associated with hypertrophy of the tensor fasciae latae muscle

OBJECTIVE: To evaluate the association between hypertrophy of the tensor fasciae latae muscle and abductor tendon tears. MATERIALS AND METHODS: Thirty-five patients who underwent MRI of the abductor tendons of the hip were included in this retrospective study. A subgroup of 18 patients was examined bilaterally. The area of the tensor fasciae latae muscle and the area of the sartorius muscle (size reference) were quantified at the level of the femoral head, and a ratio was calculated. Two radiologists assessed the integrity of the gluteus medius and minimus tendon in consensus. Data were analyzed with a Mann-Whitney U test. RESULTS: Sixteen out of 35 patients (46 %) had a tear of the gluteus medius or minimus tendon. The ratio of the area of the tensor fasciae latae to the sartorius muscle was significantly higher (p = .028) in the group with an abductor tendon tear (median 2.25; Interquartile Range [IQR] = 1.97-3.21) compared to the group without any tears (median 1.91; IQR = 1.52-2.26). The bilateral subanalysis showed that in patients without a tear, the ratio of the two areas did not differ between each side (p = .966), with a median of 1.54 (primary side) and 1.76 (contralateral side). In patients with an abductor tendon tear the ratio was significantly higher (p = .031) on the side with a tear (median 2.81) compared to the contralateral healthy side (1.67). CONCLUSION: Patients with abductor tendon tears showed hypertrophy of the tensor fasciae latae muscle when compared to the contralateral healthy side and to patients without a tear
