A 73-year-old man was admitted for sudden onset of dyspnea with cardiogenic shock. Chest X-P showed bilateral severe pulmonary edema. Echocardiogram demonstrated diffuse severe hypokinesis of left ventricle. ⋯ Left ventricular wall motion was improved after bypass grafting and cardiopulmonary bypass was weaned with catecholamine and IABP support. The patient was discharged from hospital 60 days after the operation with good cardiac function. We emphasized a usefulness of combined use of IABP and PCPS to provide systemic organ perfusion and reduce myocardial infarct size and ischemic damages after re-vascularization for coronary insufficiency with profound shock.

Between may 1993 and march 2001, 2 patients with tetralogy of Fallot and an anomalous coronary artery crossing the right ventricular outflow tract underwent intracardiac repairs. The anomalous coronary arteries included the left anterior descending from the right coronary artery (case 1), and the right coronary artery from the left coronary artery (case 2). ⋯ In case 2, we underwent transpulmonary-transatrial repair and placed a transannular patch along by the left coronary artery. Right ventricular outflow tract reconstruction was successful in 2 cases.

A 56-year-old female admitted with severe back pain, and her chest computed tomography demonstrated non-dissecting sclerotic aneurysm of the ascending aorta. Aortography and echocardiography showed marked dilatation of the ascending aorta and the Valsalva sinuses resulting in disappearance of the sinotubular junction. ⋯ A woven Dacron double-veloured graft (Hemashield) of 22 mm in diameter was used for reconstruction of the ascending aorta and its root. Postoperative aortography figured the new sinotubular junction and the new Valsalva-like sinus composed by the graft, and aortic regurgitation was controlled to grade one.

Conotruncal repair for tetralogy of Fallot consists of (1) precise closure of the VSD with the membranous flap and (2) reconstruction of the right ventricular outflow tract (RVOT) by a short transannular patch (< 30% of the RV length) with a wide PTFE monocusp. This report describes the mid-term results in 46 patients with tetralogy of Fallot who underwent conotruncal repair with PTFE monocusped transannular patch and have been followed up for 4 years or more. There was no early and late death and no patient required reoperation. ⋯ The mobility of the PTFE monocusp was echocardiographically detected in 86% over a mean follow-up period of 84 +/- 34 months and % freedom from pulmonary regurgitation (> II) was 85.9% at 10 years postoperatively. Excellent long-term durability of the PTFE monocusp provided the normal right vent performance with RVEDV of 91.8 +/- 29.5% of normal and a central venous pressure of 5 +/- 1 mmHg. In conclusion, conotruncal repair with a wide and short transannular patch has provided good mid-term results with the excellent long-term durability of PTFE monocusp.
