Abstract
Aortic cusp prolapse is an acquired complication and usually precedes the development of aortic regurgitation (AR) in unoperated outflow ventricular septal defect (VSD). However, its impact on postoperative AR-progression is unknown. 161 patients with outflow-VSD and AR who underwent surgery between 2006 and 2012 were studied retrospectively. 31 patients without prolapse (group-I), 87 with only right coronary cusp (RCC) (group-II), 43 with noncoronary cusp (NCC) prolapse (group-III: 23 only NCC (IIIa), 20 both NCC-RCC (IIIb)) were followed postoperatively for a mean 6.05 ± 2.4 years (range 3-12 years). Moderate or severe-AR was present in 4.2%, 36.8%, 52.2% and 80% preoperatively; in 3.2%, 10.3%, 39.1% and 30% patients at follow-up in group-I, II, IIIa, and IIIb, respectively. Although freedom from significant-AR (moderate or severe AR) or aortic valve replacement (AVR) at 10 years was lesser in subaortic-VSD than subpulmonic-VSD (64.3 ± 7.5% vs 87.9 ± 3.6%; P = 0.02), the difference was not significant when compared within prolapse groups (80 ± 8% vs 88.7 ± 4.0%, P = 0.28 in group-II; 40.7 ± 11.8 vs 70 ± 14.5%, P = 0.48 in group-III). The significant-AR or AVR free survival in patients with trivial or mild preoperative-AR was not significantly different between prolapse groups (98.2 ± 1.8% vs 75 ± 21.7% in group-II and III respectively; P = 0.85). However, in those with moderate or severe preoperative-AR it was significantly lesser in group-III than II (30.1 ± 9.8% vs 65.6 ± 8.4%, respectively; P = 0.04). Group-III, compare to group-II, had 3.28 and 5.24-time risk of development of significant-AR or requirement of AVR, respectively. Prolapse of NCC alone or in addition to RCC prolapse has unfavourable impact on the postoperative outcomes, especially in subaortic-VSD after development of more than mild AR preoperatively.

Ann Thorac Surg 2021; 114:873-880.

Abstract
BACKGROUND Ideal time of surgery still remains controversial in outflow ventricular septal defect (VSD) with aortic regurgitation (AR). We aimed to identify the prevalence and predictors of postoperative AR progression. METHODS 154 patients with outflow-VSD and AR who underwent VSD surgery between 2006 and 2012 were studied retrospectively. RESULTS Total 80 patients with subpulmonic-VSD and 74 with subaortic-VSD were followed-up for mean 6.32+/-2.27 years (range 3-12 years). Of them, 100 had trivial to mild (group-A) and 54 had moderate to severe preoperative-AR (group-B). At follow-up, There was no significant worsening of mean residual AR in group-A (p=0.16) and subpulmonic-VSD of group-B (p=0.083). However, it worsened significantly in subaortic-VSD (1.85+/-0.87 vs 2.21+/-1.08, p=0.005) of group-B. Only 2 (both had subaortic-VSD) patients of group-A developed moderate AR and none required aortic valve replacement (AVR), while 23 (42.60%) of group-B patients developed moderate or severe AR and 7 (30.4%) of them required AVR. Moreover, all who needed AVR had subaortic-VSD and had undergone valvuloplasty during VSD-closure. The 10 years freedom from moderate or severe-AR was significantly lower in group-B than group-A in both VSDs (subaortic-VSD 42.5+/-10.7% vs 89.3+/-8.1%, p<0.01; subpulmonic-VSD 66.7+/-10.3% vs 100%, p<0.01). On multiple regression analysis, postoperative residual-AR was the only predictor of AR-progression (standardized coefficients =0.48; p<0.001) at follow-up. CONCLUSIONS Mild preoperative-AR rarely progressed after VSD-repair. However, worsening of AR could not be prevented effectively, even with valvuloplasty, after the development of moderate or severe AR. Mild or more postoperative residual-AR need close follow-up, especially in subaortic-VSD.

Abstract
BACKGROUND Outcome data of doubly committed subarterial ventricular septal defect closure in adults are limited. METHODS A review was made of the inpatients >18 years of age who underwent doubly committed subarterial ventricular septal defect closure between June 2010 and June 2017. RESULTS The patients were categorised into two groups: The valve intervention group consisted of 31 patients who underwent aortic valvuloplasty, aortic valve replacement, or repair of sinus Valsalva aneurysm in addition to doubly committed subarterial ventricular septal defect closure; non-valvular intervention group comprised 58 patients who underwent only doubly committed subarterial ventricular septal defect closure. The groups did not differ by sex and age. Patients in the valve intervention group, with a larger ventricular septal defect size, were shorter and tended to be lighter. The valve intervention group had more patients with pneumonia perioperatively. No infective endocarditis and reoperation were noted during the study period. At last follow-up, 91 and 96.6% of the studied patients were free from left ventricle dilation and pulmonary hypertension. In patients without pre-operative aortic regurgitation, 12 developed new mild aortic regurgitation during the follow-up. CONCLUSIONS About 34.8% of adult patients with doubly committed subarterial ventricular septal defect required concurrent intervention on aortic valve or sinus Valsalva aneurysm. The midterm results of doubly committed subarterial ventricular septal defect closure in adult patients were favourable. However, the incidence of new mild aortic regurgitation after ventricular septal defect closure was high (27.3%). Long-term follow-up of aortic regurgitation progression is needed.

Abstract
The medical records of 2283 patients with ventricular septal defect (VSD) were reviewed to determine spontaneous closure, left ventricular-to-right atrial shunt, subaortic ridge, and aortic valve prolapse. One thousand eight hundred and twenty-three patients had been followed 1 month to 26 years (median 4 years) by echocardiography. Most of 460 patients could not be followed due to transportation of the institution. VSD was perimembranous in 68.8% (1255), trabecular muscular in 21.7% (395), muscular outlet in 6% (109), muscular inlet in 2.6% (48), and doubly committed subarterial in 0.9% (16). Defect size was classified in 66.8% (1218) as small, in 15.7% (286) as moderate, and in 17.5% (319) as large. VSD closed spontaneously in 18.8% (343 of 1823 patients) by ages 40 days to 24.9 years (median, 1.8 years). One hundred fifty-seven of 1255 perimembranous defects (12.5%) and 167 of 395 trabecular muscular defects (42%) closed spontaneously (p < 0.001). Defect size became small in 306 (16.8%) of patients with VSD at a median of 2.5 years. Aneurysmal transformation was detected in 32.9% (600), left ventricular-to-right atrial shunt in 9.7% (176), subaortic ridge in 2.6% (48) of 1823 patients who were followed. In 381 (20.9%) of the 1823 patients, the VSD had been closed by a surgical or transcatheter technique. Surgery is required in one-fifth of patients with subaortic ridge or aortic valve prolapse. In conclusion, isolated VSDs are usually benign abnormalities that tend to shrink and close spontaneously.

Abstract
Aortic valve repair in children is a challenge. We have adopted a technique of single aortic cusp extension with an autologous pericardial strip in patients diagnosed with severe aortic insufficiency (AI) associated with a ventricular septal defect (VSD). The purpose of this study was to report the short-term outcomes. Seven patients were operated on between January 2002 and December 2003. The mean age was 11.28 ± 2.1 years (range 8–14 years). The VSD was closed with a synthetic patch. Aortic cusp extension was performed at the right coronary cusp in 6 patients and the remainder had a non-coronary cusp extension. The mean diastolic arterial pressure increased from 35.71 ± 6.09 to 74.28 ± 7.31 mm Hg after the operation ( p < 0.001). The postoperative grade of AI was trivial in 4 patients, mild in 1 patient and non-existent in 2 patients. The mean follow-up period was 12.85 ± 6.12 months (range 2–20 months). This technique is very effective in patients with severe AI associated with a VSD. However, long-term durability will need to be carefully followed.

Abstract
BACKGROUND Although surgery is recommended for pediatric patients with supracristal ventricular septal defects (sVSDs) to prevent progression of aortic regurgitation (AR), outcomes in adolescents and adults with sVSDs are not known. METHODS In this retrospective observational study, clinical data without surgery were obtained in 60 patients with sVSDs (group 1; mean age, 36 ± 13 years), 120 age- and defect size-matched patients with perimembranous ventricular septal defects (group 2), and 52 patients with sVSDs who underwent surgery (group 3; mean age, 32 ± 11 years). RESULTS Aortic sinus wall prolapse (38% vs 3%, P < .0001) and moderate to severe AR (7% vs 0%, P = .012) were more frequently observed in group 1 than in group 2. Five, three, and two patients in group 1 had surgery during follow-up because of rupture of the aneurysm of the sinus of Valsalva, endocarditis, and heart failure, respectively. Group 1 had a lower 12-year clinical event-free (surgery and endocarditis) rate (76 ± 9% vs 94 ± 4%, P = .031) but an equivalent overall survival rate (100% vs 94 ± 3%, P = .143) compared with group 2. Patients with maximal prolapsing aortic sinus wall length > 7 mm showed a higher frequency of aneurysm of the sinus of Valsalva rupture than those with no prolapse or maximal prolapsing length ≤ 7 mm (80% [four of five] vs 2% [one of 55], P < .001). The event-free and overall survival rates were comparable between groups 1 and 3, with equivalent 10-year AR progression-free survival rates (94 ± 5% vs 91 ± 5%, P = .301). CONCLUSIONS Aneurysm of the sinus of Valsalva rupture, rather than AR progression, was the main clinical event. Watchful monitoring of patients with high-risk echocardiographic features may be a rational option.

Abstract
The natural history of aortic cuspal prolapse and aortic regurgitation (AR), studied most commonly in subpulmonic ventricular septal defect (VSD), has not been well defined in isolated, unrepaired VSD diagnosed during infancy. This study aimed to define the incidence and progression of aortic cuspal prolapse and AR in patients with subaortic VSDs diagnosed at <1 year of age who had no aortic cuspal prolapse or AR at presentation and did not require surgery within the first year of life. Patients had yearly follow-up, and data regarding clinical course, physical examination, and echocardiography were obtained. Comparisons were made between patients who developed aortic cuspal prolapse and AR and those who did not. One hundred patients, with a mean age at VSD diagnosis of 0.1 +/- 0.5 years, followed for a mean of 7.1 +/- 10.1 years, were studied. Aortic cuspal prolapse developed in 14 patients (14%) at a mean age of 7.1 +/- 6 years (range 0.4 to 18.4). AR murmurs were heard in 6 patients (6%) at a mean age of 5.1 +/- 3.1 years, all of whom had aortic cuspal prolapse and underwent VSD closure and aortic valvuloplasty. In conclusion, aortic cuspal prolapse and clinical AR are not uncommon in patients with subaortic VSDs. Long-term follow-up of patients with subaortic VSDs should include the serial evaluation of aortic valve anatomy and function.

Abstract
Development of aortic regurgitation (AR) can complicate an isolated perimembranous ventricular septal defect (VSD). The objective of this study was to identify echocardiographic features of perimembranous VSDs associated with AR. Echocardiograms were evaluated for the presence of aortic cusp override, aortic cusp movement abnormality, and presence of color flow mapping across the ventricular septum in a standard, parasternal long-axis view. Echocardiograms of 26 patients with isolated VSDs were included in the study, 13 had AR and 13 had no evidence of AR. Aortic cusp override in the apical 5-chamber and subcostal coronal views were correlated with the presence of AR, with high sensitivity and low specificity. Flow across the septum in the parasternal long-axis view was associated with AR, with moderate sensitivity and specificity. Aortic cusp movement abnormalities had high sensitivity and low specificity. Our data indicate that these findings may identify patients with perimembranous VSD susceptible to AR.

Abstract
INTRODUCTION AND OBJECTIVES Interventricular fibromuscular septal defects of the outlet tract are subarterial infundibular ventricular septal defects (VSDs). This anatomical situation predisposes to aortic cusp prolapse (AoP) and/or regurgitation (AoR). METHODS In order to determinate the frequency of VSDs and the presence or development of aortic valve alterations detected by two-dimensional echocardiography, we studied 35 patients with VSDs. The defect area and presence, severity, and evolution of AoP and/or AoR were evaluated. Ten anatomic specimens were studied to verify the echocardiographic correlation. RESULTS Subarterial infundibular defect was present in 6.9% of all ventricular septal defects. The average age at time of diagnosis was 5,8 years. VSDs diameter and gradient did not change during follow-up. At time of diagnosis, 30 patients (87%) did not have AoR, but during an average follow-up of 8 years, 11 (32%) developed it. By the end of the study, 46% had AoR. When the time to progression of AoR was compared in the group that developed it versus the group that did not, the median values were similar in both groups. There was a greater tendency to development and/or progression of regurgitation in small VSDs. The echo-anatomic correlation was precise. CONCLUSIONS Aortic valve damage was a frequent finding in VSD. Most cases did not progress to more severe AoR. Small VSDs developed more severe regurgitation in less time. Surgery must be considered when AoR is detected. Regular evaluation by echocardiography is important in follow-up.

Abstract
BACKGROUND Previous reports on the long-term outcome of surgical closure of subarterial ventricular septal defect were based on a relatively small number of patients. METHODS We reviewed the long-term outcome of 135 patients who underwent closure of their defect and, in light of the findings, assessed the impact of preoperative aortic cusp prolapse and surgical interventions on occurrence of aortic regurgitation (AR) in the long-term. The patients were categorized into three groups for comparison: group I consisted of 79 patients with no aortic cusp prolapse and underwent simple closure of ventricular septal defect, group II comprised 39 patients with mild to moderate cusp prolapse who similarly had only closure of the defect performed, whereas group III comprised 17 patients who had additional aortic valvoplasty for greater than moderate to severe cusp prolapse. RESULTS Group I patients had significantly higher pulmonary arterial pressure (p < 0.001) and ratio of pulmonary blood flow to systemic blood flow (p < 0.001). None of these patients had AR before their operation, and none experienced AR afterward at a median follow-up of 6.1 years. Of the 39 group II patients, 30 (77%) had trivial or mild AR preoperatively. The AR improved in 15 patients, remained trivial or mild in 14 and absent in 7, but progressed to trivial or mild in 3 at a median follow-up of 3.1 years. None required further interventions. In contrast, 14 (82%) of the 17 group III patients had moderate to severe AR before operation. The regurgitation improved in 10, but remained moderate or severe in 4 and worsened further in 3 at a median follow-up of 4.6 years. The freedom from failure of aortic valvoplasty was (mean +/- standard error of the mean) 71%+/-11%, 64%+/-12%, and 43%+/-19% at 1, 5, and 10 years, respectively. An older age at latest follow-up was the only identifiable significant risk factor (p = 0.03). CONCLUSIONS Our data do not support the need of aortic valvoplasty for mild to moderate aortic cusp prolapse. Close follow-up is warranted in those with greater than moderate to severe cusp prolapse despite valvoplasty as there is continued failure on follow-up. Nothing, however, is better than early closure of defects before development of aortic valve complications.

Abstract
The records of 153 patients with doubly committed subarterial ventricular septal defect (DCVSD) who underwent intracardiac repair were analyzed to evaluate factors responsible for aortic valve leaflet deformity. The patients were divided into two groups according to their echocardiographic and angiographic features as well as anatomic findings at operation: DCVSD without (17/153, 11.1%) and with arterial valve offsetting (136/153, 88.9%). Aortic regurgitation (AR) was much more prevalent in the patients with (50.0%) than in those without leaflet deformity (2.2%, P < 0.01). Arterial valve offsetting is one of the major contributing factors to the development of leaflet deformity, accounting for 5.9% in the patients without offsetting and 46.3% in those with offsetting (P < 0.01). Among the patients with arterial valve offsetting, the pulmonary-to-systemic pressure ratio was significantly higher (P < 0.01) in the patients without (0.76 +/- 0.14) than in those with leaflet deformity (0.36 +/- 0.12), suggesting that pulmonary hypertension might prevent the aortic valve leaflet from prolapsing in DCVSD. In addition, increased severity of aortic valve leaflet deformity and subsequent AR were observed with increasing age. These results suggest that aging and the presence of arterial valve offsetting as well as the absence of pulmonary hypertension might be factors responsible for aortic valve leaflet deformity and subsequent AR in DCVSD. The anatomic and hemodynamic features in DCVSD have a great impact on the development of aortic valve leaflet deformity and subsequent AR.

Abstract
BACKGROUND From 1986 to March 1997, 128 patients diagnosed to have doubly committed subarterial ventricular septal defects (VSD) were reviewed. Patients with aortic regurgitation (AR), and aortic valve (AV) deformity or a large left-to-right shunt across the VSD were offered operation. Forty-five patients (27 men, 18 women) agreed to surgical closure of their VSDs. METHODS Thirty-eight patients had VSD closure alone, and 7 had an additional AV repair. Other associated defects corrected at operation were closure of atrial septal defects, closure of other ventricular septal defects, ligation of patent ductus arteriosus, and repair of ruptured sinus Valsalva aneurysm. RESULTS There was no mortality nor major morbidity associated with operation. In the 26 patients with AR and AV deformity preoperatively, valve repair was performed in 6 patients. The condition of AR improved in 4, and remained unchanged in 22 patients. In the 10 patients with a deformity of the AV and no AR preoperatively, the condition remained unchanged in 5 patients, from whom 1 had valve operation, but progressed in 5 patients postoperatively at a mean follow-up of 6.4 years. In 9 patients with no deformity of the AV and no AR preoperatively, there was no postoperative AR and no progress of valve deformity. CONCLUSIONS Excellent results were obtained with VSD closure and AV repair. Surgical closure of VSD, if performed before the onset of AV deformity, may prevent progressive AR. If AV repair is performed after the onset of AV deformity, progressive AR may not always be prevented.

Abstract
BACKGROUND Many surgeons recommend early repair of doubly committed subarterial ventricular septal defect regardless of the clinical symptoms. We reviewed our patients of this anomaly with aortic cusp prolapse to justify this strategy. METHODS We reviewed the preoperative and postoperative records of 27 patients with doubly committed subarterial ventricular septal defect and aortic cusp prolapse. The patients' ages ranged from 2 months to 11 years (median, 4.6 years). RESULTS During the preoperative observation period, aortic regurgitation (AR) developed in 65% of the patients. In the 8 patients without AR before the operation, AR did not develop after the operation, whereas AR persisted in 12 (63%) of the 19 patients with preoperative AR. To identify the risk factors for persistent AR after the operation we analyzed the data for the patients with preoperative AR in the persistent AR group (n = 12) and eliminated AR group (n = 7) and found a longer period from the onset of AR to the operation in the persistent AR group (32.1 +/- 10.1 versus 5.6 +/- 1.9 months; p = 0.014). During the follow-up period 10 of the 17 patients with mild AR before the operation showed persistent AR in the postoperative period, but it did not progress. CONCLUSIONS We conclude that early surgical repair with a minimum observation period is essential for prevention of residual AR. Even if a tiny AR is detected preoperatively, the patient should be surgically treated immediately.

Abstract
In order to further understand the natural history and timing of repair for subpulmonic (type I) ventricular septal defect (VSD), 70 patients who underwent radical surgery were reviewed. The patients with this type of VSD accounted for 30 per cent of a total 236 children with types I, II and III VSD who underwent repair between 1978 and 1989. The frequency of aortic regurgitation was 30 per cent, being higher in the group aged older than 10 years than in the younger group (p less than 0.05). The median ages of patients with normal, prolapsed and regurgitated valves were 5, 6.5, and 10 years, respectively, and each value exhibited significant differences (p less than 0.05). The left to right shunt ratio and systolic pulmonary artery pressure of the patients with normal valves were significantly higher than those of the patients with abnormal valves. The outcome of the patients with regurgitation varied according to Sellers grading with cases of grade two valvular deformities recovering well after the repair, while cases of grade three had deformities of grade one or two severity remaining. These results led us to establish the following strategy for patients with I-VSD: 1) a child should be regularly checked by USG; 2) a child noted as having a prolapsing valve is recommended to undergo repair by the age of 10 to 12 years; and 3) a child found to have regurgitation should undergo repair as soon as possible, unless the valve regurgitation does not become more severe than Sellers grade two.

Abstract
Twenty-two patients with a ventricular septal defect and aortic incompetence underwent surgical repair. Mean age was 9.6 years (range, 9 to 15 years). Mean follow-up was 32.4 +/- 15.8 months. The ventricular septal defect was perimembranous in 19 patients and doubly committed or juxtaarterial in 3. Most showed only a small left-to-right shunt. Mean diameter was 11.9 +/- 4.8 mm. Aortic incompetence was mild in 6 patients, moderate in 4, and severe in 12. In 16 patients closure of the ventricular septal defect and aortic valvoplasty were both performed through the aortic root. There were no deaths. All patients retained normal sinus rhythm. No complete heart block was found. In 3 patients secondary aortic valve replacement was required for severe incompetence; in 1 the cause was bacterial endocarditis, in another technical failure, and in a third progressive incompetence over an 8-month period. All patients showed substantial clinical improvement, marked decrease or disappearance of the valvar incompetence, diminution of the left ventricular end-diastolic diameter, and decreased cardiothoracic ratio. We conclude that primary repair is the operation of choice for this combination of lesions. This can avoid or delay considerably valvar replacement. The left-sided approach proves safe and is our preferred technique.

Abstract
From 1946 to March 1989, 92 patients (33 women and 59 men) were seen with ventricular septal defect (VSD) and audible aortic regurgitation (AR). The VSD was subcristal in 62 patients, subpulmonary in 21 and unknown in the remaining 9. The median age of onset of AR was 5.3 years. The risk of developing AR was 2.5 times greater in those with a subpulmonary VSD. The aortic valve was tricuspid in 90% and bicuspid in 10%. Prolapse was seen in 90% of those with subcristal VSD and in all with subpulmonary VSD. Pulmonary stenosis was seen in 46% of the patients with gradients ranging from 10 to 55 mm Hg. The incidence of infective endocarditis was 15 episodes/1,000 patient years. Among 20 patients followed medically, for 297 patient years, 1 died (1959) and most have been stable, including 2 followed for greater than 30 years. In the 72 patients operated on, there were 15 perioperative and 5 late deaths. Operations consisted of VSD closure alone in 7, VSD closure and valvuloplasty in 50 and VSD closure and aortic valve replacement in the other 15. Valvuloplasty was more effective in those operated on under age 10 compared to those older than 15 years (46 vs 14%). The durability of the valvuloplasty was 76% at 12 years and 51% at 18 years.

Abstract
Doubly committed subarterial (supracristal, subpulmonary) ventricular septal defects are often complicated by aortic regurgitation resulting from aortic valve herniation into the defect. The clinical, echocardiographic and catheterization findings in 48 patients aged 0.3 to 46.4 years (median 9.5) with a doubly committed subarterial ventricular septal defect were reviewed. Aortic valve herniation was present in 38 (79%) and 55% of these had aortic regurgitation. The prevalence of both findings increased gradually with advancing age. The defect was closed surgically in 41 patients. Surgery during the first 2 years of life (median 0.4 year) was performed in 13 patients (group I), mainly because of a large shunt with a pulmonary to systemic flow ratio (Qp/Qs) 3.8 +/- 1.4 (mean +/- SD). Aortic regurgitation was present preoperatively in two patients (15%), persisted postoperatively in one patient and did not develop in any after repair (median duration of follow-up 2.3 years, range 0.1 to 7.4). In the other 28 patients (group II) surgery was performed between 4.8 and 46.4 years of age (median 11.5). These patients were generally less symptomatic and had a smaller shunt (Qp/Qs 1.5 +/- 0.5, p less than 0.001). Preoperative aortic regurgitation was present in 18 (64%). It persisted in 15 postoperatively, but in 13 of these it had diminished. Two-dimensional echocardiography in multiple views identified the site of the ventricular septal defect in all patients. Serial echocardiographic examinations demonstrated the progressive nature of aortic valve herniation, the partial occlusion of the defect by the herniated sinus and the development of aortic regurgitation. These findings suggest that timely surgical closure of these defects may prevent aortic regurgitation.

Abstract
Doppler, contrast, and two-dimensional echocardiograms of 12 aneurysms of the sinus of Valsalva in 10 consecutive patients were analyzed in order to highlight the diagnostic features. The diagnosis were confirmed by surgical and/or catheterization findings. The aneurysms had ruptured in 7 of 12 (58%). Two-dimensional echocardiography prior to the contrast studies was able to delineate the aneurysms in 7 of 12 (58%). The contrast studies outlined two additional aneurysms. The right aneurysms directed anteriorly and caudally. The noncoronary aneurysms formed an extraneous lumen at the posterior part of the aortic root, mimicking aortic dissection. Doppler examinations showed systolic and diastolic turbulence in five of six (83%) of the right aneurysms rupturing into the right ventricular outflow tract. Color Doppler echocardiography showed a left ventricular diastolic turbulence emanating from the aneurysm in a case with a noncoronary aneurysm rupturing into the left ventricle. It is concluded that the principal Doppler, contrast, and two-dimensional echocardiographic features usually allow a rapid correct diagnosis of sinus of Valsalva aneurysm.

Abstract
Twenty consecutive patients with ventricular septal defect and aortic valve prolapse were evaluated by cross-sectional echocardiography. Angiographic confirmation was available in all and surgical confirmation was found in 17. In 19, the right coronary cusp was involved and appeared to plug the defect in the precordial long- and short-axis cut. The cusp was deformed and appeared to pivot from the crest of the interventricular septum. In all 19 angiography demonstrated prolapse of the right cusp. Noncoronary cusp prolapse was observed in two by cross-sectional echocardiography and in six by angiocardiography. The ventricular septal defect was perimembranous in 14 and doubly committed subarterial in six by echocardiography. Angiographically, the ventricular septal defect was felt to be perimembranous in 15 and doubly committed in five. Aortic regurgitation was detected by Doppler interrogation in seven, all of whom underwent plication of the right coronary cusp. Angiographic evidence of regurgitation was noted in 11, but four were mild and possibly related to catheter position. Five patients had associated muscular right ventricular outflow tract obstruction and three had a subaortic ridge. Combined cross-sectional and pulsed Doppler echocardiography provide a reliable assessment of right coronary cusp prolapse associated with a ventricular septal defect. Noncoronary cusp prolapse appears more difficult to detect. This technique should help optimize the management of patients by providing a means of early detection prior to the development of aortic regurgitation.

Abstract
The incidence of aortic valve prolapse and aortic regurgitation (AR) among Chinese with ventricular septal defect (VSD) has not been studied, and controversies still exist regarding optimal surgical treatment and timing of operation for this condition. A prospective study of 332 consecutive patients with VSD showed that aortic valve prolapse and AR occurred in 43 (11.9%) patients. Valve lesions occurred more commonly among patients with subpulmonic VSD (28.0%) than with subaortic VSD (8.8%) (P less than 0.005). A retrospective study of another 306 patients revealed that 37 (12.1%) had valve complications. Of the 80 patients with valve lesions, 60 were males and 20 were females. The youngest ages of prolapse and AR in subpulmonic VSD were 7 months and 3 years 8 months, respectively; those in subaortic VSD were 2 years and 3 years 6 months, respectively. Valve prolapse occurred mostly before the age of 6-10 years, leading progressively to AR. The coronary cusps prolapsed in subpulmonic VSD were limited to the right cusp; and those in subaortic VSD were the right cusp, noncoronary cusp, or both. The magnitude of left-to-right shunts was small and the pulmonary artery pressure was normal in the majority of patients. Seventy-two patients underwent open-heart closure of the VSD, with additional valvuloplasty in 15 and valve replacement in three patients. It is concluded that Chinese with VSD are prone to develop aortic valve complications. Surgical closure of the subpulmonic VSD may restore the prolapsed valve to normal. Closure of the subaortic VSD has little effect. Valvuloplasty in subaortic VSD may palliate AR, but in all probability cannot restore valve competency.

Abstract
Development of aortic valvular deformities was studied retrospectively in 395 inpatients with subarterial infundibular ventricular septal defect (siVSD). Aortic valvular deformities included prolapse into siVSD without aortic regurgitation (77 patients), prolapse and aortic regurgitation (95 patients), and aneurysm of the sinus of Valsalva (36 patients). No aortic valvular deformity was found in 187 patients, and 111 of these 187 patients had associated pulmonary hypertension. Prolapse and regurgitation of the aortic valve developed most frequently at the age 5 to 8 years. Aneurysm of the sinus of Valsalva was not found before the age of 10 years but began to develop during the teens and was diagnosed most frequently in the twenties. Patients with pulmonary hypertension did not develop aortic valvular deformities except in one instance. All inpatients with siVSD and without pulmonary hypertension over the age of 30 years had developed some aortic valvular deformities.
