AbstractBackgroundInterrupted aortic arch is often associated with subaortic narrowing and hypoplasia of the aortic orifice. The best surgical strategy for the management of these additional lesions is a matter of current debate.Methods and ResultsBetween 1986 and 1996, 19 patients underwent repair of interrupted aortic arch with closure of ventricular septal defect in a single stage, with no attempt at subaortic resection, irrespective of the dimensions of the left ventricular outflow tract. There was no perioperative hospital mortality, and all patients were alive at 1 year. Follow-up ranges from 0.75 −10 years, with a mean 4.2 ± 3.0 years. Seven patients (37%) have required reintervention for relief of subaortic stenosis, 2 of whom have died.ConclusionsOur results suggest that primary one-stage biventricular repair can be accomplished with low perioperative mortality without addressing the subaortic region. Further long-term follow-up will determine whether this is accomplished at the expense of later morbidity and mortality.

Abstract OBJECTIVES Aortico-left ventricular tunnel (ALVT) is an extremely rare, abnormal paravalvular communication between the aorta and the left ventricle. Few studies have identified the characteristics and long-term prognosis associated with ALVT. METHODS The data of 31 patients with ALVT from July 2002 to December 2019 were reviewed. Echocardiography was performed in all patients during the follow-up period. RESULTS The median age of the patients was 11.5 years. Bicuspid aortic valve and dilatation of the ascending aorta were found in 13 patients, respectively. The aortic orifice in 20 patients showed a close relation to the right sinus and the right–left commissure. Of the 31 patients, 26 were operated on. Mechanical valve replacement was performed in 4 patients and aortic valve repair, in 6 patients. Ascending aortoplasty was performed in 5 patients and aortic replacement was done in 2 patients. One patient died of ventricular fibrillation before the operation. Follow-up of the remaining 30 patients ranged from 1 to 210 months (median 64 months). There were 4 deaths during the follow-up period: 1 had mechanical valve replacement and 3 did not undergo surgical repair. In the 26 patients without aortic valve replacement, 6 had severe regurgitation and 2 had moderate regurgitation. In the 28 patients without replacement of the ascending aorta, 11 had continued dilatation of the ascending aorta, including those who had aortoplasty. CONCLUSIONS The aortic orifice of ALVT showed an association with the right sinus and the right–left commissure. For patients who did not have surgery, the long-term survival rate remained terrible. Surgical closure should be done as soon as possible after ALVT is diagnosed. The main long-term complications after surgical repair included aortic regurgitation and ascending aortic dilatation.

Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the aorta to the left ventricle. The authors report the history of a 14-year-old boy with aortico-left ventricular tunnel in whom the aortic orifice arose from the right aortic sinus and was closed by a pericardial patch. The diagnosis was confirmed by combined two-dimensional and real time three-dimensional echocardiogram and magnetic resonance imaging. This is the first case, in which these complex diagnostic imaging methods have been used in the pre- and postoperative management of this defect. Optimally the new transthoratic three-dimensional echocardiography would be needed to define the anatomy and functional consequences of the aortico-left ventricular tunnel and in the postoperative follow-up.

Objective: To estimate the mean of morphometric values of the human aortic valve in the population of western Maharashtra. The morphometric variables include mean area and the circumference of the human aortic valve of both genders. Materials and Methods: The present study was carried out on 30 adult cadaveric hearts in the department of Anatomy at a tertiary care hospital in western Maharashtra. Heart and aortic arch were dissected according to standard dissection techniques. The aortic orifice and valves were exposed; pictures were taken keeping a plastic ruler alongside the periphery of the valve. The pictures were analyzed using Image J software to calculate circumference and area of the aortic valve. Results: The mean circumference of the aortic valve was 8.827 cm in males and 8.179 cm in females.  The mean area of the male aortic valve was 5.365cm² and the female aortic valve is 4.641cm². The circumference results were found to be significant whereas the area results were not significant. Conclusion: The size of the aortic valve in the western Maharashtra region was found to be more as compared to other studies. The present study might help the cardiothoracic surgeons as well as the prosthetic valve manufacturing companies for the rough estimation of the aortic valve size. Keywords: Aortic valve, valve area, valve circumference
