Primary percutaneous transluminal coronary angioplasty in the acute infarction of the right ventricle.

BACKGROUND: Predilection site for the acute myocardial infarction of the right ventricle, (AMI-RV) is the upper third of the right coronary artery and for this reason such an infarction is followed by numerous complications, primarily by conduction disorders and very often by sudden and rapid cardiogenic shock development. METHODS: Primary percutaneous transluminal coronary angioplasty (PPTCA) was performed on three patients, in whom the acute infarction of the right ventricular was diagnosed and who had been hospitalized six hours after the beginning of chest pain. In all three patients intracoronary stent was implanted. On the admission patients had been in the threatening cardiogenic shock, with the prominent chest pain and with the elevation of ST-segment in V4R > 2 mV. In the course of intervention patients were administered low-molecular intracoronary heparin, with direct platelet glycoprotein IIb/IIIa inhibitors (abciximab), according to the established procedure applied in such cases. RESULTS: The complete dilatation of the infarcted artery was established with the signs of reperfusion and the further clinical course was completely normal, there was no heart failure and patients had no subjective difficulties. CONCLUSION: Invasive approach in the treatment of AMI-RV is justifiable, and possibly the therapy of choice of these patients, providing well trained and equipped team is available.

[Chylous effusions].

This paper presents 4 patients with chylothorax, and one patient with bilateral chylothorax and chyloperitoneum. The chylous effusions were of benign etiology, developed as a complication of miliary tuberculosis (1 patient), after L-2 vertebral body fracture (1 patient), and idiopathic (2 patients). The diagnosis was confirmed by the presence of chylomicrons and high content of triglycerides in the effusion, ranged 11.9-29.1 mmol/l. Lymphangiography showed multiple abnormalities of lymphatic system, the obstruction of ductus thoracicus, dilatation and convulsion of lymphatic channels, but the site of lymphatic leak was not detected. The treatment included an extended period of pleural and peritoneal drainage with total parenteral nutrition (1 patient), pleurodesis using Corynebacterium parvum (2 patients), and surgical partial parietal pleurectomy with continuous drainage (1 patient). The treatment was successful in all patients.

Autologous bone marrow-derived progenitor cell transplantation for myocardial regeneration after acute infarction.

BACKGROUND: Experimental and first clinical studies suggest that the transplantation of bone marrow derived, or circulating blood progenitor cells, may beneficially affect postinfarction remodelling processes after acute myocardial infarction. AIM: This pilot trial reports investigation of safety and feasibility of autologous bone marrow-derived progenitor cell therapy for faster regeneration of the myocardium after infarction. METHODS AND RESULTS: Four male patients (age range 47-68 years) with the first extensive anterior, ST elevation, acute myocardial infarction (AMI), were treated by primary angioplasty. Bone marrow mononuclear cells were administered by intracoronary infusion 3-5 days after the infarction. Bone marrow was harvested by multiple aspirations from posterior cristae iliacae under general anesthesia, and under aseptic conditions. After that, cells were filtered through stainless steel mesh, centrifuged and resuspended in serum-free culture medium, and 3 hours later infused through the catheter into the infarct-related artery in 8 equal boluses of 20 ml. Myocardial viability in the infarcted area was confirmed by dobutamine stress echocardiography testing and single-photon emission computed tomography (SPECT) 10-14 days after infarction. One patient had early stent thrombosis immediately before cell transplantation, and was treated successfully with second angioplasty. Single average ECG revealed one positive finding at discharge, and 24-hour Holter ECG showed only isolated ventricular ectopic beats during the follow-up period. Early findings in two patients showed significant improvement of left ventricular systolic function 3 months after the infarction. There were no major cardiac events after the transplantation during further follow-up period (30-120 days after infarction). Control SPECT for the detection of ischemia showed significant improvement in myocardial perfusion in two patients 4 months after the infarction. Echocardiographic assessment in these two patients also showed significant improvement of systolic function three months after the infarction. CONCLUSION: Preliminary results of the study showed that the transplantation of bone marrow-derived progenitor cells into the infarcted area was safe, and feasible, and might improve myocardial function. Further follow-up will show if this treatment is effective in preventing negative remodeling of the left ventricle and reveal potential late adverse events (arrhythmogenicity and propensity for restenosis).
