INTRODUCTION: We previously reported the clinical outcomes of a large pediatric cohort with discrete subaortic stenosis (SubAS) 1 . While patients with more significant left ventricular outflow tract obstruction (LVOTO) at diagnosis progressed rapidly others with mild LVOTO at presentation showed little progression of obstruction or aortic insufficiency (AI). A limitation of our previous study was a relatively short follow-up period. OBJECTIVE: To extend the follow-up of our previously described cohort with SubAS. METHODS: Information was gathered retrospectively on 71 previously identified patients diagnosed with SubAS from 1985–1998. RESULTS: Current data was available on 61/71 patients. At diagnosis the average age was 5.2±0.5 years (mean±SEM), peak LVOT Doppler gradient (Echograd) was 30±3 mmHg, and AI (all mild) was present in 25%. At last assessment the average age was 15.7±0.4 years. Twenty patients were followed only medically and were last reassessed 9.2±1.0 years after diagnosis at 15.8±0.7 years of age. The mean Echograd was unchanged from diagnosis (19±2 vs. 19±3 mmHg). The incidence of AI on echocardiography (all mild) increased from 5% to 55% although none was detectable by auscultation. Forty-one patients underwent surgery 3.0±0.5 years after diagnosis at 7.4±0.6 years of age. The Echograd at diagnosis was 35±3 and increased to 61±6 mmHg pre-operatively. Ten patients were re-operated 5.7±0.7 years after the first surgery and 2 patients had a second re-operation. The last follow up of the operated patients occurred at 15.7±0.6 years of age. At that time the Echograd was 16±3 mmHg and the incidence of AI by echocardiography had increased to 98% (36 mild & 3 moderate) but was evident on auscultation in only 25%. CONCLUSIONS: This study represents the largest and longest contemporary follow-up of pediatric patients with discrete SubAS. Our results indicate that some patients with SubAS show significant LVOTO at diagnosis and subsequent progression. Surgery in these patients provides good relief of LVOTO but does not eliminate AI. The one third of patients presenting with mild LVOTO and AI show little progression through childhood and adolescence. We suggest that the latter can be safely followed medically. 1) Rohlicek et al.

Left Ventricular Outflow

Abstract Background Subaortic stenosis (SAS) was a rare congenital heart disease of left ventricular outflow tract (LVOT), ranging from “isolated” lesions to “tunnel” or “diffuse” lesions. We conducted a retrospective study to describe the characteristics of patients with different lesions and analyze the risk factors for reoperation. Methods In this study, we examined a single-center retrospective cohort of SAS patients undergoing resection from 2010 to 2019. Patients were classified as simple lesion group (n = 37) or complex lesion group (n = 28). Demographics, perioperative findings, and clinical data were analyzed. Results The surgical effect of the two groups was significantly lower than that before the operation (p <0.05). The median age at operation was 6(3-11.8) years. There was no operative mortality. In complex lesion group, extracorporeal circulation time (CPB time), aortic cross clamp time (ACC time), mechanical ventilation time and ICU stay time were longer. The median follow-up period was 2.8 years (range 1-3.8), with two late death. Six patients (9.2%) required reoperation due to restenosis or severe aortic insufficiency. The freedom from reoperation rates at 5 years was 66.7% for simple lesion but only 52.3% for complex lesion (p = 0.036). Conclusions Although the lesions include many forms, subaortic stenosis resection was still satisfactory. However, the reoperation after initial surgical treatment was not infrequent, especially in patients with complex lesion.

Left Ventricular Outflow

On the basis of our clinical experience, we hypothesized that the role of mitral valvar anomalies in the development and recurrence of discrete subaortic stenosis might be underestimated. From January 1994 to October 2000, the anatomy of the mitral valve and its relationship to the other components of the left ventricular outflow tract were studied by echocardiography in a series of 73 consecutive patients referred to our institution for surgical correction of discrete subaortic stenosis. In all patients for whom it was considered advisable, surgical correction of the mitral anomaly was performed, together with resection of the fibro-muscular subaortic stenosis. One or more mitral valvar anomalies were found in 35 patients (48%). They could be grouped into five categories: insertion of a papillary muscle into the aortic leaflet, insertion of a papillary muscle into the ventricular wall, “muscularization” of the subaortic portion of the aortic leaflet, anomalous insertion of the valvar tissue into the ventricular wall, and accessory valvar tissue. In all cases with anomalous mitral valvar anatomy, surgical correction was feasible. It consisted of transection of the anomalous papillary muscle or its attachment, resection of accessory valvar tissue, and/or patch enlargement of the aortic leaflet. The incidence of mitral valvar anomalies associated with subaortic stenosis is probably underestimated. Our data suggest that they should be systematically searched for during the evaluation of all cases of subaortic stenosis. Their surgical correction is generally feasible, and might improve the mid and long term results.

A 75-year-old was treated for prostate adenocarcinoma with brachytherapy in September 2018. A routine follow-up chest radiograph 3 months later revealed a metallic object of the same dimensions as a brachytherapy pellet located in the right ventricle. Further imaging showed the brachtherapy pellet was located in the anterobasal right ventricular endocardium close to the tricuspid valve. Frequent asymptomatic premature ventricular contractions were observed with likely origin from the left ventricular outflow tract, an area remote from the site of the pellet. The patient remains asymptomatic and subsequent imaging shows that the position of the pellet has not changed.

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.

Introduction Hypertrophic obstructive cardiomyopathy (HOCM) is a hereditary heart muscle disorder characterized by significant myocardial hypertrophy. we assessed perioperative and long-term follow-up data of Iranian HOCM patients who underwent SM in 2 pioneering centers. Methods Clinical data of patients with HOCM septal myectomy are collected. Thirty-day outcome and long-term follow-up data for recurrence of gradient and mortality are reported. Results Ninety-six patients in two different centers enrolled in the study. Most patients of 52 patients in center 1 were male (34/52 [65.3%]).and the mean age was of 36.7  ±  19 years. Syncope before admission was reported in 5.7%, the mean left ventricular ejection fraction on admission was 53  ±  8%, the mean left ventricular outflow tract gradient was 66.3  ±  20.4 mm Hg, and the mean preoperativeseptal thickness was 25.4  ±  6.7 mm. A redo SM was performed in 3 patients (5.8%), mitral valve repair in 5 patients (9.6%), and atrioventricular repair in 5 patients (9.6%). A residual systolic anterior motion was detected in 4 patients (7.7%), the mean postoperative septal thickness was 19  ±  6 mm (25.1% septal thickness reduction), and in-hospital mortality was 5.8% (n  =  3). A longer-term follow-up showed death in 3 patients (5.8%) and late recurrent left ventricular outflow tract obstruction in 1 patient. Conclusions Transaortic myectomy is an effective surgery with acceptable early and late mortality rates. Improvements in functional status are seen in almost all patients. Appropriate SM is crucial to a good clinical outcome. Long-term survival is excellent and cardiac sudden death is extremely rare after a good surgical treatment.

Objective: Prenatal diagnosis, postnatal followed up of three cases of cardiac tumor and successful postnatal surgery of one case. Methods: Treatment and postnatal followed up of three cases of cardiac tumor. Those cases were diagnosed by fetal echocardiography. One of them underwent a successful postnatal surgery. Results: Three fetuses were diagnosed with fetal cardiac tumor (capable of Rhabdomyoma) at 28, 27, 38 gestational weeks. There were many tumors in one or two ventricles. These cases were referred to Hue Central Hospital for timing and location of delivery in 2019. One of them had obstruction of left ventricular outflow tract with successful surgical resection at 46 hours after birth. One of them had heart failure after birth. Evolution of three cases was favorable, heart failure regressed, cardiac tumors regressed at 7 - 9 months follow up. Conclusions: Fetal cardiac tumor can be diagnosed prenatally. Those three cases were capable of rhabdomyoma due to the presence of muliple tumors and their regression after birth. Neonatal surgical option should be reserved for the risk of cardiac flow obstruction.
