Reassessment of the natural evolution and complications of temporary epicardial wires after cardiac surgery.

Objective: The aim of this study was to prospectively reassess the natural evolution and complications of temporary epicardial wires (TEW) after cardiac surgery.

Design: Observational prospective study.

Setting: Monocentric.

[Development of indications in surgery of coronary revascularization. Current role of mammary-coronary anastomoses].

At a time when the cardio-surgical community has become aware that arterial revascularizations are superior to venous bypasses, GRUNTZIG (24) initiated the now well-known, and highly successful techniques of endoluminal angioplasty (P.T.C.

[Continuous venovenous hemofiltration after cardiac surgery. A retrospective study in 16 patients with multiple organ failure].

As intermittent haemodialysis in critically ill patients is often associated with circulatory instability and hypotension, pumped continuous veno-venous haemofiltration (CVVH) has been proposed as an alternative. This technique was used postoperatively in 16 cardiac surgery patients with cardiogenic shock (cardiac index < 2.2 l.

Penetration of ciprofloxacin into heart valves, myocardium, mediastinal fat, and sternal bone marrow in humans.

The penetration of ciprofloxacin into heart tissue (valve and myocardium), mediastinal fat, and sternal bone marrow was the object of a prospective nonrandomized study involving 36 patients undergoing mitral and/or aortic valve replacement. Patients were divided into two groups of 18. Group 1 patients were administered a single 400-mg intravenous dose of ciprofloxacin over a 1-h period.

[Value of continuous venous blood oxygen measurement during external circulatory assistance].

A case is reported of a 40 year-old man, on the waiting-list for heart transplantation, who developed terminal heart failure. Using an Opticath catheter and a radial artery catheter, SV(-)O2 was monitored continuously, and cardiac output, pulmonary arterial and wedged pressures, and right atrial pressure were repeatedly measured. Despite appropriate treatment (adrenaline, dobutamine, glyceryl trinitrate), the patient remained in anuria and cardiogenic shock.

[Plasma and tissue concentrations of cefamandole during cardiac surgery].

This study aimed to determine plasma (CPC) and tissue concentrations of cefamandole during cardiac surgery, so as to compare them with the minimal inhibitory concentration (MIC) for staphylococci (0.25 - 1 microgram.ml-1 for S.

Endarterectomy of the left main coronary artery stenosis by a 'transpulmonary artery approach'.

For better visualization of the left main coronary artery, a new technique involving transection of the main pulmonary artery is described. With this new method it was possible to perform endarterectomy of the left main coronary artery in 35 patients from February 1981 to July 1987. The endarterectomy incision was closed with a pericardial or venous patch.

Cardiorespiratory function and pathological findings in heart-lung block reimplanted after hypothermic preservation.

A good result from the heart-lung transplantation depends on the quality of the preservation of cardiopulmonary transplants. To determine the functional and pathological status of the heart-lung block after preservation for several hours, we performed 10 heterologous heart-lung transplantations in Beagle dogs (weight 13.5 kg) under extracorporeal circulation.

[Emergency coronary surgery after transluminal coronary angioplasty].

Twenty-five patients underwent emergency coronary arterial bypass surgery immediately after attempted percutaneous transluminal coronary angioplasty (PTCA). The average time between the onset of PTCA complication and revascularization was 90 min (30-120 min). The surgical indications, the anaesthesia and the perioperative intensive care were analysed.

[Surgery of the left coronary trunk by the transpulmonary approach. 10 cases].

The most common lesions of the left main coronary artery are atheromatous lesions (1% of all "coronary patients") but traumatic lesions may occur during coronary arteriography or percutaneous coronary angioplasty. To these must be added severe infectious lesions of the aortic annulus in acute endocarditis affecting the valve or a valvular prosthesis. The 10 cases reported here (4 atheromatous, 1 traumatic and 5 infectious lesions) were treated by transpulmonary repair surgery of the left main vessel.

[Early coronary spasm after myocardial revascularization surgery].

Six cases of early post-operative coronary artery spasm were observed in a series of 460 consecutive patients who underwent myocardial revascularization. This is a rare accident, only quite recently described. The spasm involves the coronary arterial network or the graft and is reflected in an elevated ST segment accompanied by collapse and ventricular dysrhythmia.
