Robotically enhanced telemanipulation surgery is a rapidly developing technique which enables totally endoscopic cardiac surgery with utmost precision and perfection on both beating heart and arrested heart. Between December 2002 and September 2006, 268 patients underwent robotically enhanced coronary artery bypass surgery using the da Vinci telemanipulation system. Fourteen patients underwent ...
Background: Measuring end tidal carbon dioxide (ETCo2) is one of the methods used for estimating arterial carbon dioxide (PaCo2) during general anesthesia. ETCo2 measurements maybe obviate the need for repeating arterial puncture for determination of arterial PaCo2. This study performed to determine the accuracy of ETCo2 levels as a measure of PaCo2 levels in patients undergoing coronary artery...
BACKGROUND Left internal thoracic artery-to left anterior descending artery grafting has become a fundamental part of coronary artery bypass grafting. This grafting has led to increased use of other arterial conduits, of which the radial artery is most popular. Whether radial grafting can be used in the emergency patient is not known. This study compares the short-term clinical evolution betwee...
Introduction: Reciprocal changes are ST depression ≥1 mm in electrocardiogram of the patients with acute myocardial infarction in the reciprocal leads. This question that these changes are merely secondary to ST elevation in infarction area or that they are truly subendocardial ischemia secondary to involvement of coronary artery that perfuse that area is not clearly defined. Methods and Materi...
Spontaneous coronary artery dissection is an unusual cause of acute coronary syndrome. We describe a series of cases that with an early diagnosis and aggressive treatment, which includes percutaneous angioplasty with stent implantation and cardiac surgery, had a good outcome. The objective was to study the demographic characteristics, clinical settings, treatments, and inhospital course of pati...
A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In pat...
Background and purpose: Infection is one of the most important complications after coronary artery bypass surgery. The purpose of this study was to evaluate the risk factors for infection in these patients. Materials and methods: A descriptive prospective study was performed in 986 patients hospitalized in Sari Fatemeh Zahra hospital, Iran 2014-2015. Possible risk factors for infection (befo...
Coronary aneurysms are typically seen in association with Kawasaki disease and only in rare instances, they are reported to be congenital or idiopathic. Here we report a case of a five year old boy who was found to have an idiopathic right coronary artery aneurysm. He presented with complaints of recurrent respiratory tract infections. His examination and investigations did not reveal any of th...
The evolution of minimally invasive direct coronary artery bypass (MIDCAB) grafting has extended the role of this approach for limited coronary revascularization. MIDCAB techniques can now be used to address isolated stenoses in the inferior and lateral coronary distributions. MIDCAB techniques are increasingly being used in the reoperative setting, and multiple vessels can be bypassed during a...
