Minimally invasive direct coronary artery bypass has been widely employed as an approach for revascularization of the left anterior descending coronary artery. Recent advances in minimally invasive cardiac surgery enhanced with technological assistance have meant that these operations are now being performed through smaller incisions. We present 2 cases, both ...

In off-pump coronary artery bypass surgery, an appropriate method for intraoperative evaluation of grafts and vessels has been awaited. We report the usefulness of a 15-MHz linear transducer for this purpose. A 15-MHz linear transducer with a SONOS 5500 (Philips Medical Systems, Best, Netherlands) was applied epicardially in off-pump coronary ...

We report the case of a 65-year-old man who developed norepinephrine-resistant vasoplegic syndrome after elective off-pump coronary artery bypass surgery (OPCAB). The failure of norepinephrine to improve the patient's hemodynamics prompted us to start treatment with vasopressin; within 30 minutes, the hemodynamics began to improve. After 12 hours, the patient ...

BACKGROUND: Bypass surgery requires the shortest temporary occlusion time of a recipient artery during anastomosis. For this purpose, we have devised a microforceps with attached scissors that makes it possible to perform the multiple steps involved in anastomosis without exchanging instruments. This microforceps avoids having to exchange instruments twice in ...

The inferior epigastric artery has been used as an alternative arterial conduit in coronary artery bypass graft surgery. Its harvesting requires a single or double, long abdominal paramedian incision that is technically difficult and does not yield a good cosmetic result. We describe an alternative new approach to one or ...

Cholesterol crystal embolization (CCE) is a complication of atherosclerosis. A 67-year-old Japanese man underwent coronary artery bypass grafting. After the surgery, he underwent coronary angiography via the right femoral artery. Twelve days later, he suddenly developed acalculous cholecystitis and was treated with antibiotics. Gradual deterioration in renal function, purplish discoloration ...

Extracorporeal support during cardiac surgery initiates an inflammatory response, causing damage to cardiac, pulmonary and renal tissue [Post Pump Syndrome (PPS)]. This is accompanied by a neutrophil leucocytosis and lymphopenia, but less is known about the role of monocytes and markers of monocyte activity. We studied 19 patients undergoing cardiac ...

BACKGROUND: Cardiac surgery is generally well or over-represented in many Western countries. Since the southern part of Switzerland relies on 300 km distance centers for cardiac surgery, we started a project of telemedicine for the distant evaluation of cardiac surgery candidates. We report our experience of the results of the ...

The majority of patients undergoing coronary bypass surgery have at least one internal thoracic artery used as a conduit. Internal thoracic artery atherosclerosis is a rare but distal anastamotic stenosis or occlusion can occur often early after surgery. Percutaneous coronary intervention is a management option. A patient with a left ...

After coronary artery bypass graft surgery, most patients will have a small, unilateral, left-sided pleural effusion, and approximately 10% of patients will have a larger effusion. These large effusions can be separated into (1) early effusions occurring within the first 30 days of surgery that are bloody exudates with a ...
