RESUMO
A 57-year-old man was referred to our hospital due to dyspnea on exertion with severe mitral regurgitation. Because he had underdone right pneumonectomy 37 years earlier due to congenital defect of the right pulmonary artery, his mediastinum was severely shifted to the right, and his pulmonary function was poor. Mitral valve repair was successfully performed with right thoracotomy approach, which made excellent exposure of the mitral valve. The patient was extubated three hours after the surgery. He was discharged on the 30th postoperative day without postoperative respiratory complications. With an appropriate plan of the surgery and postoperative optimal management, cardiac surgery can be performed on patients with a single lung.

OBJECTIVE: Despite the broadened indications for Fontan procedure, there are patients who could not proceed to Fontan procedure because of the strict Fontan criteria during the early period. Some patients suffer from post-Glenn complications such as hypoxia, arrhythmia, or fatigue with exertion long after the Glenn procedure. We explored the possibility of Fontan completion for those patients. METHODS: Between 2004 and 2010, five consecutive patients aged between 13 and 31 years (median 21) underwent Fontan completion. These patients had been followed up for more than 10 years (10 to 13, median 11) after Glenn procedure as non-Fontan candidates. We summarise these patients retrospectively in terms of their pre-operative physiological condition, surgical strategy, and problems that these patients hold. RESULTS: Pre-operative catheterisation showed pulmonary vascular resistance ranging from 0.9 to 3.7 (median 2.2), pulmonary to systemic flow ratio of 0.3 to 1.6 (median 0.9), and two patients had significant aortopulmonary collaterals. Extracardiac total cavopulmonary connections were performed in three patients, lateral tunnel total cavopulmonary connection in one patient, and intracardiac total cavopulmonary connection in one patient, without a surgical fenestration. Concomitant surgeries were required including valve surgeries--atrioventricular valve plasty in three patients and tricuspid valve replacement in one patient; systemic outflow tract obstruction release--Damus-Kaye-Stansel procedure in two patients and subaortic stenosis resection in one patient; and anti-arrhythmic therapies--maze procedure in two patients, cryoablation in two patients, and pacemaker implantation in two patients. All patients are now in New York Heart Association category I. CONCLUSION: Patients often suffer from post-Glenn complications. Of those, if they are re-examined carefully, some may have a chance to undergo Fontan completion and benefit from it. Multiple lesions such as atrioventricular valve regurgitation, systemic outflow obstruction, or arrhythmia should be surgically repaired concomitantly.

A woman with a single coronary artery underwent aortic valve replacement due to aortic stenosis. Two years later, she developed an aortic annular abscess around the right coronary cusp and non-coronary cusp. Significant adhesions to the right coronary artery (RCA) resulted from the abscess, making artery separation challenging, and raising concerns about potential future RCA stenosis. The patient subsequently underwent aortic root replacement and coronary artery bypass grafting. Utilizing a freestyle valve and a saphenous vein graft for the RCA. Following the procedure, the patient was discharged and has remained symptom-free without any recurrence of infection for 2 years.
RESUMO
The authors report a 71-year-old male with descending thoracic aortic aneurysm and multiple risk factors (aortoiliac occlusive disease, obesity, ascending aorta dilatation, and history of left ventriculoperitoneal shunt for hydrocephalus) who was treated with thoracic endovascular aortic repair (TEVAR) via left common carotid artery (LCCA) access and left axillary-carotid artery (Ax-CA) bypass; this approach shortened the LCCA clamp time during the procedure. The patient was discharged without any complications. TEVAR via LCCA access with left Ax-CA bypass is a useful and safe procedure for patients in whom conventional femoral artery access is not feasible.
RESUMO
Ostial atresia of the left main coronary artery (LMCA) in children without any primary disease is extremely rare. We present here a case of occlusion of the LMCA in a 9-year-old girl. Myocardial scintigraphy showed poor perfusion in both domains of the left anterior descending artery (LAD) and left circumflex artery (LCx). Coronary artery graphy (CAG) showed complete ostial atresia of the LMCA and retrograde perfusion from the thin collateral arteries into the LAD. We performed angioplasty using an autologous pericardium onlay patch. Her postoperative course was unremarkable. Postoperative CAG showed vanishing collateral arteries, confirming anterograde flow through the LAD and LCx, and myocardial scintigraphy showed improvement in perfusion.

A combination of cor triatriatum and persistent left superior vena cava without communication to the coronary sinus is uncommon. A 62-year-old male with this diagnosis in conjunction with atrial fibrillation underwent successful intracardiac repair done with a unique method. After a maze procedure and enlargement of the route from the pulmonary veins to the mitral valve, a GoreTex graft was used to reroute the left superior vena cava into the right atrium and to close two thirds of the circumference of the patient's atrial septal defect; the rest of the defect was closed with another GoreTex patch.

Although indications for a Fontan procedure have broadened, some patients, in the past, were ineligible for the Fontan completion after a Glenn procedure and thus suffered the limitations of the Glenn procedure-namely desaturation, arrhythmia and reduced quality of life. If examined more closely, however, completion may yet be feasible for such patients. We present here a complex case of asplenia, dextrocardia and total anomalous pulmonary venous return (1b) where the Fontan procedure was successfully completed 12 years after the Glenn procedure. A unique surgical strategy incorporating intra-atrial total cavopulmonary connection and atrioventricular valve repair contributed to our success.
