Aortic valve replacement through right minithoracotomy: is it really biologically minimally invasive?

Background: Minimally invasive aortic valve replacement through a right mini-thoracotomy is a procedure developed in the past few years. Currently, the main limits of this technique are longer cardiopulmonary bypass time compared with the standard approach and the need for peripheral cannulation.

Methods: From January 2010 to March 2014, 206 patients underwent an aortic valve replacement using a minimally invasive technique through a right mini-thoracotomy.

Thoracic aortic aneurysm in infancy in aneurysms-osteoarthritis syndrome due to a novel SMAD3 mutation: further delineation of the phenotype.

Recently, mutations in the SMAD3 gene were found to cause a new autosomal dominant aneurysm condition similar to Loeys-Dietz syndrome (LDS), mostly with osteoarthritis, called aneurysms-osteoarthritis syndrome (AOS). Our 3-year-old propositus underwent correction of an inguinal hernia at 3 months and substitution of the ascending aorta for pathologic dilation at 12 months of age. Family history reveals aortic dilation in his mother at 30 years, death due to aortic dissection of an 18-year-old maternal aunt, surgical replacement of the ascending aorta because of aneurysm in a maternal uncle at 19 years, postpartum death of the maternal grandmother at 24 years and surgical intervention because of thoracic aortic aneurysm in a brother of the propositus' grandmother at 54 years.

Left main coronary artery stenosis secondary to severe pulmonary artery dilation.

A 45-year-old lady with dyspnea and occasional precordial chest pain was diagnosed with a huge sinus venosus atrial septal defect and partial anomalous pulmonary venous return. Preoperative coronary angiography disclosed severe main stem stenosis, considered secondary to compression by the dilated pulmonary trunk. Atrial septal defect closure and pulmonary artery reduction plasty were performed.

Pulmonary artery banding.

Pulmonary artery banding (PAB) is a simple surgical technique to reduce pulmonary overcirculation in some congenital heart disease. In the beginning, when the use of cardiopulmonary bypass was affected by many deleterious effects, this technique played a fundamental role in the treatment of patients with congenital heart defects and an intracardiac left-to-right shunt. The use of PAB has decreased during the last two decades, due to the increasing popularity of early complete intracardiac repair, which results have shown to be superior to staged repair, even in low body weight patients.

Pulmonary artery debanding.

Pulmonary artery banding is a simple palliative surgical procedure for congenital heart defects with left-to-right shunt or complete mixing and pulmonary over-circulation. Even though indication for pulmonary artery banding has been sensibly reduced, since early reparative surgery has been proved superior to palliation and a staged approach, an increasing support for pulmonary banding has been raised in the last two decades by new indications such as left ventricular retraining, in the late arterial switch operation for complete transposition of the great arteries or before the double-switch operation in congenitally corrected transposition. Along with the increasing interest raised by the new indications and the consequently more diffuse use of banding, debanding has become an important surgical issue.

Aortopulmonary window and anomalous coronary artery: an exceptional association.

Aortopulmonary window is rarely associated with other cardiac anomalies, such as anomalous origin of one coronary artery. This exceptional association has been reported in 15 patients, with different surgical solutions. We describe 2 patients with aortopulmonary window with anomalous origin of the right coronary artery, one of which presented with tetralogy of Fallot-pulmonary atresia.

Incidence, etiology, histologic findings, and course of thoracic inflammatory aortopathies.

Background: The aims of this study were to detect the incidence of thoracic histologically proven aortitis in a large series of 788 patients operated on for thoracic aortic disease, to describe the surgical and histologic features of inflammatory thoracic aortopathies, and to evaluate the frequency of postsurgical complications and mortality.

Methods: Thirty-nine patients (4.9%) were affected by aortitis (mean age, 72.

Antegrade selective cerebral perfusion in thoracic aorta surgery: safety of moderate hypothermia.

Objective: Although antegrade selective cerebral perfusion (ASCP) has been demonstrated to be the best method of protection of brain ischemia during aortic arch surgery, there is no consensus regarding optimal temperature during ASCP. The study analyzed the outcomes of aortic surgery using ASCP at different degree of systemic hypothermia.

Methods: Between November 1996 and November 2005, 305 patients underwent thoracic aorta surgery using ASCP.

Moderately hypothermic cardiopulmonary bypass and low-flow antegrade selective cerebral perfusion for neonatal aortic arch surgery.

Background: Although deep hypothermic circulatory arrest has been extensively used in neonates for aortic arch surgery, the brain and other organs might be adversely affected by prolonged ischemia and deep hypothermia.

Methods: Between December 1997 and January 2005, 70 consecutive neonates underwent Norwood stage I procedure for hypoplastic left heart syndrome (group A, n = 30), or aortic arch repair for interruption or coarctation with arch hypoplasia (group B, n = 40), with antegrade selective cerebral perfusion (ASCP). Mean weights were 3.

Right superior vena cava draining in the left atrium: anatomical, embryological, and surgical considerations.

A newborn, with SDS (S = situs viscero-atrialis solitus, D = D-loop of the ventricles, S = solitus, normally related great arteries) anomalous drainage of the right superior vena cava in the left atrium, intact atrial septum, and anomalous drainage of the right superior pulmonary veins in the right superior vena cava, underwent surgical repair at our institution. This rare cyanotic, congenital, cardiac malformation is herein described with particular regard to its anatomical, embryological, and surgical implications.

Double orifice tricuspid valve in an infant with tetralogy of Fallot.

Atrioventricular valve duplication, also known as double orifice valve, is an excitingly rare anomaly that can involve either the mitral or more uncommonly the tricuspid valve. Herein we describe a case of a double orifice tricuspid valve that prejudiced the complete repair in a symptomatic infant with tetralogy of Fallot.
