Yenidoğan Bir Buzağıda Çoklu Kongenital Kardiyak Defektlerin Tanısı

Bu olguda çoklu kalp defekti olan 15 günlük, erkek Simmental buzağıya diyagnostik yaklaşım planı ve olguya kardiyopulmoner by-pass tekniği ile cerrahi yaklaşımın sonuçları sunulmuştur. Buzağı solunum stresi ve büyüme geriliği şikayeti getirildi. Kardiyak oskültasyonda kalbin her iki transtorasik alanında titreşimle beraber yüksek pansistolik üfürüm belirlendi. Ayrıca kardiyomegali, pulmoner arter dolgunluğu (röntgen) ve atriyal fibrilasyon gözlendi. Renkli Doppler transtorasik ekokardiografide muskulomembranöz ventriküler septal defekt (VSD), atriyal septal defekt (ASD) ve soldan sağa şant ile beraber patent duktus arteriozus (PDA) tespit edildi. Rutin hematolojik ve serum biyokimyasal profiller nonspresifikti. Buzağıda çoklu kardiyak defektlerin cerrahi yolla düzeltlmesi için lateral torakotomi yapıldı. Kardiyopulmoner by-pass sırasında, buzağı hemodinamik dengesizlikler ve ventriküler fibrilasyon nedeni ile hayatını kaybetti. Nekropside çoklu kardiyak defekt varlığın ortaya konuldu.

Diagnosis of Multiple Congenital Cardiac Defects in a Newborn Calf

This case report presents the clinical diagnostic work-up and surgical approach via cardiopulmonary by-pass technique in 15 day-old, male,Simmental calf with multiple cardiac defects. Calf suffred from respiratory stress and poor growth. Cardiac auscultation revealed a loudpansystolic murmur with cardiac trill of both transthoracic area of the heart. Cardiomegaly and pulmonary artery bulge (x-ray) and atrialfibrillation were observed. Color Doppler transthoracic echocardiography revealed musculomembranous ventricular septal defect (VSD), atrialseptal defect (ASD) and patent ductus arteriosus (PDA) with left to right shunt. Routine hematological and serum biochemistry profiles werenon-specific. Calf underwent to lateral thoracotomy for surgical correction of multiple cardiac defects. During the cardiopulmonary by-pass, calfwas dead due to hemodynamic imbalances and ventricular fibrillation. Necropsy confirmed the presence of multiple cardiac defects in this case.
