Transaortic double valve replacement in difficult mitral valve exposure.

Adequate open exposure of the mitral valve is necessary to accomplish reconstruction or replacement of the diseased mitral valve apparatus. The technique employed by most cardiac surgeons for mitral valve access involves median sternotomy and vertical left atriotomy posterior to the interatrial sulcus. However, certain conditions can somethimes make this approach very difficult. Different approaches are discussed with particular emphasis on our case in which the transaortic double valve replacement have been performed.

[Surgical revascularization of the myocardium].

It has been 45 years ago when Longmire (1958.) used internal thoracic artery (ITA) for the first time in coronary artery bypass surgery (CABG). In this review, we are presenting novel surgical approaches in CABG surgery. We have also been summarized the best of knowledge, up to date, regarding histology, pharmacology and pathophysiology of conduits (VSM, ITA and alternative venous and arterial grafts) which have been used in CABG surgery, as well as factors influence on its short and long-term patency.

[Role of the Swan-Ganz pulmonary artery (PA) catheter in evaluation of hemodynamic changes during myocardial revascularization in patients with low left ventricular function].

Coronary artery bypass surgery in patient with bad left ventricular function is a challenge for surgical time. Specially important is monitoring of haemodynamics. We performed this open, prospective, randomized study with the aim to assess haemodynamics and oxygen profile monitoring. 34 pts for coronary surgery (EF < 40%) were divided in two groups. Group A, 17 pts. Received glucose-insulin-potassium (GIK) solution. Group B, 127 pts. Received Ringer solution. Haemodynamic and oxygen metabolism parameters were measured in four time points. I after the induction in anesthesia; II after the operation; III 6 hours post op.; IV 24 hour post op. Data are expressed as mean +/- SD, Anova for repeated measures followed by Newman-Keuls testing were used. In both groups were evident deterioration of cardiac function during first 6 h as well as VO2 and DO2, more prominent in Group B. Significant recovery and improvement of cardiac function were evident in Group A after 24 h. CI during the time in Group A improves significantly (2.14 +/- 0.36 v. 3.05 +/- 0.55; p = 0.0002) and difference during the time between groups was p = 0.005. LVSWI improved significantly during the time him Group A (AIII vs. AIV) p = 0.007. Simultaneously. VO2 improves significantly in Group A (103 +/- 21 vs. 164 +/- 30, p = 0.00001) while difference between groups in DO was p = 0.037. Importance of oxygen metabolism monitoring for both, left ventricular function and haemodynamics assessment was evident in our study.

[Use of the internal thoracic artery in repeat myocardial revascularization surgery].

The incidence of redo myocardial revascularization is increasing lately. These procedures are accompanied by the higher operative risk, and the use of internal thoracic artery graft may have additional negative impact on early-rization. Mortality and morbidity in this group did not differ significantly compared to a group where only venous grafts were used. Independent predictors of the unfavorable outcome (for both groups) were the presence of the chronic pulmonary disease, age over 65 and NYHA functional class IV. In the group with internal thoracic graft it was the age over 65, while in the group with only vein grafts it was chronic pulmonary disease. We have discussed potential problems during the redo procedure in patients in whom internal thoracic graft was used during the first procedure.

[Assisted circulation. I. Systems with short-term mechanical circulatory support].

The concept of artificial circulatory support has been established almost 200 years ago. It has only been within the last four decades that physicians and engineers have developed mechanical assist devices that can temporarily support the circulation until the native heart recovers from a reversible injury. If the heart does not recover sufficient function to maintain adequate hemodynamics, long-term circulatory support or permanent replace (biologically--heart transplant or permanent mechanical circulatory support) is needed. In this paper we describe the devices (intraaortic balloon pump, roller, centrifugal and axial pumps), that are in current clinical use for temporary (short-term) mechanical circulatory support.

[Occlusion of a calcified ascending aorta with a Foley catheter in aortocoronary bypass--case report].

Heavily calcified ascending aorta predisposes to aortic injury and distal embolization during total or partial cross-clamping, during the performance of open-heart procedures. Placement of the arterial cannula may be particularly difficult, occasionally virtually impossible using the standard technique, while placing the clamp on such aorta may be extremely risky. We present a case where we have used a Foley-balloon catheter to occlude the densely calcified ascending aorta, during a aorta-coronary bypass procedure, thus completely avoiding the use of the total aortic clamp.
