[Apicoaortic valved conduit as an alternative method of surgical treatment of aortic stenosis - a case report]. / Wszczepienie protezy zaopatrzonej w zastawke pomiedzy koniuszkiem lewej komory a aorta zstepujaca jako alternatywna metoda operacji zwezenia zastawki aortalnej - opis przypadku.

A case of a 73-year-old patient with critical aortic stenosis, porcelain aorta and occluded femoral arteries is presented. We performed apico-aortic valved conduit (A-AVC) without cardiopulmonary bypass (CPB). Hegar dilator inserted through the apex into the left ventricle allowed anastomosis of dacron tube to the apex. Valved conduit was anastomosed to the descending aorta. Both tubes were connected. Before the operation, maximal gradient through the valve was 95, after operation dropped to 33 mmHg. This method of apical anastomosis allowed to perform A-AVC without CPB in a patient with extremely high peri-operative risk while using CPB.

A case of a 50-year-old woman with prosthetic mitral valve complicated by severe thrombosis as an effect of incorrect anticoagulation treatment during rectal cancer biopsy, is presented. During echocardiographic evaluation a dysfunction prosthetic mitral valve with extremely high maximal mitral gradient (50.2 mmHg) was found. The patient was qualified for surgical intervention and mechanical prosthetic mitral valve was replaced by a biological one. This report underlines the difficulties in the anticoagulation therapy in patients with prosthetic heart valves.
