Use of combined cutting balloon and high-pressure balloon technique for the treatment of double-chambered right ventricle or primary infundibular stenosis: a case series. J Vet Cardiol 2024; 53:6-12. [PMID: 38555707 DOI: 10.1016/j.jvc.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 12/18/2023] [Accepted: 01/05/2024] [Indexed: 04/02/2024]
Abstract
Five dogs and two cats with a diagnosis of double-chambered right ventricle or primary infundibular stenosis were referred to undergo a combined cutting balloon and high-pressure balloon technique. At admission five cases were asymptomatic, one had a history of syncope and one had signs of right-sided congestive heart failure. Each patient underwent a complete transthoracic echocardiogram, thoracic radiographs, an angiogram and the combined interventional procedure. Median diameter of the right mid-ventricular stenosis was 4 mm (range 2-8.7 mm) in dogs, and it measured 1.9 and 2 mm in cats. Under general anesthesia initial dilation with an 8-mm × 2-cm cutting balloon was performed from a left external jugular vein approach followed by dilation with a high-pressure balloon (1.5:1 balloon diameter-right outflow tract diameter ratio). In one dog and the two cats the procedure was not completed due to technical issues. In the other four dogs the median intracavitary proximal chamber pressure decreased from 100 mmHg (range 70-150 mmHg) before the procedure to 57 mmHg (range 45-70 mmHg) post-dilation. Long-term follow-up (from six months to two years) showed complete or partial reverse remodeling of the proximal chamber with a median residual pressure gradient below 80 mmHg (range 46-75 mmHg) for all four dogs. This case series shows that this procedure should be considered in dogs with right ventricular outflow tract obstruction. In cats, the procedure might be feasible, if additional guidewire inventory were available.

Abstract
Double-chambered right ventricle is a rare form of right ventricular outflow tract obstruction caused by anomalous hypertrophy of muscle bundles in right ventricle. Cases most often occur in children and rarely in adults. Most cases (80-90%) are associated with ventricular septal defect. We describe a case of pulmonary atresia and ventricular septal defect with double-chambered right ventricle. The interesting clinical findings, ECG, echocardiography and angiocardiography features are described here.

Abstract
The majority of patients with double-chambered right ventricle present during childhood; it is rarely treated in adults. We report the case of a 71-year-old woman who presented with mild fatigue for 2 years. Investigation of an ejection systolic murmur revealed a double-chambered right ventricle with a peak gradient of 147 mm Hg across the right ventricular outflow tract. Substantial right ventricular muscle bundle resection and augmentation of the right ventricular outflow tract with a bovine pericardial patch were performed after a right ventriculotomy.

Abstract
The clinical diagnosis of double chamber right ventricle (DCRV) is not straightforward. Clinical history, clinical examination, 12-lead electrocardiogram, chest X-ray, and Echocardiography (echo) contribute to morphological diagnosis. Cardiac catheterization is essential for hemodynamic evaluation. A thorough presurgical workup helps the cardiac surgeon to choose the appropriate surgical approach and timing of surgery in an individual case. We present a case of a DCRV who presented to us in the fifth decade of life. Echo confirmed the morphological diagnosis and cardiac catheterization complemented the exact pull back gradient across the obstruction in the right ventricle. This patient was suggested muscle bundle resection and ventricular septal defect closure using right atrial approach.

Abstract
Double-chambered right ventricle (DCRV) is a rare condition. Stenosis of DCRV is progressive, and early surgical intervention is recommended for patients whose symptoms and/or pressure overload of right ventricular (RV) inflow are progressive. However, there are few data regarding the postoperative course of DCRV, and the surgical indications for asymptomatic patients remain to be determined. We retrospectively investigated 38 consecutive patients who were diagnosed with DCRV and underwent surgical intervention from 1981 to 2009. Moreover, we identified 29 patients in whom long-term follow-up transthoracic echocardiographic data were available and investigated the postoperative recurrence of DCRV by evaluating the systolic pressure of RV inflow before, immediately, and in the long term after surgical intervention. The mean follow-up period was 11.0 ± 8.8 years. There were no deaths and no surgical reinterventions during the long-term follow-up period. Among 29 patients with long-term follow-up echocardiographic data, there was no recurrence of DCRV. In these patients, the systolic pressure of RV inflow by echocardiography before, immediately, and long-term after surgical intervention was 80 ± 26, 30 ± 11, and 25 ± 6 mm Hg, respectively. In conclusion, the surgical outcomes and postoperative prognosis beyond 10 years of DCRV are favorable, and neither recurrence of DCRV nor fatal arrhythmias develop during the long-term follow-up period.

Abstract
Crests, bands, chords, and membranes can be seen within the different cardiac chambers, with variable clinical significance. They can be incidental or can have clinical implications by causing hemodynamic disturbance. It is crucial to know the morphology and orientation of normal structures, aberrant or accessory muscles, and abnormal membranes to diagnose the hemodynamic disturbance associated with them. Newer generation computed tomographic scanners and faster magnetic resonance imaging sequences offer high spatial and temporal resolution allowing for acquisition of high resolution images of the cardiac chambers improving identification of small internal structures, such as papillary muscles, muscular bands, chords, and membranes. They also help in identification of other associated complications, malformations, and provide a road map for treatment. In this article, we review cross-sectional cardiac imaging findings of normal anatomical variants and distinctive imaging features of pathologic bands, chords, or membranes, which may produce significant hemodynamic changes and clinical symptomatology.

Abstract
Double-chambered right ventricle (DCRV) is an uncommon congenital anomaly in which anomalous muscle bands divide the right ventricle into two chambers; a proximal high-pressure and distal low-pressure chamber. It may be associated with mid right ventricular obstruction. It is commonly associated with other congenital anomalies, most frequently perimembranous ventricular septal defect (PM-VSD). We herein present 5 adult patients with concomitant DCRV and PM-VSD who varied in their symptomatic presentations and the ways of management.

Abstract
A double-chambered right ventricle is a rare heart defect in which the right ventricle is separated into a high-pressure proximal and low-pressure distal chamber. This defect is considered to be congenital and typically presents in infancy or childhood but has been reported to present rarely in adults. It can be caused by the presence of anomalous muscle tissue, hypertrophy of the endogenous trabecular bands, or an aberrant moderator band; all of which will typically result in progressive obstruction of the outflow tract. In this paper, we will discuss the general anatomy of the right ventricle, the relevant embryology of the heart, and the presentation, diagnosis, and treatment of a double-chambered right ventricle.

Abstract
BACKGROUND We reviewed our experience with surgical repair of double-chambered right ventricle and long-term outcome. METHODS From November 1970 to February 2008, repair of double-chambered right ventricle was performed in 61 patients (31 males). The median age was 13 years (interquartile range, 2 months to 64 years); 10 patients were infants (16%). Mean preoperative right ventricular outflow tract pressure gradient was 67±37 mm Hg. An associated ventricular septal defect was present in 50 patients (82%). RESULTS There were 2 (3%) early deaths due to persistence of low cardiac output postoperatively, despite complete relief of the right ventricular gradient. The overall mean postoperative gradient was 2±4.5 mm Hg. Late follow-up was complete in 92% (mean, 7.4±7.9 years; maximum, 37 years). Late survival was 90% at 10 years. There were 3 late deaths due to heart failure in 2 patients and sudden death in 1 patient, all occurring before 1997. No patients required reoperation for residual or recurrent right ventricular obstruction. CONCLUSIONS Surgical correction of double-chambered right ventricle results in excellent functional and hemodynamic long-term results, with complete relief of the right ventricular obstruction. The presence of a double-chambered right ventricle should be considered in anomalies with high or persistent right ventricular outflow tract obstruction.

Abstract
Introduction Double chambered right ventricle is a rare congenital cardiac anomaly in which the right ventricle is divided into two chambers by an anomalous muscle bundle. The diagnosis of this disorder is difficult in adults. Calcification of the tricuspid valve is extremely rare, and very few cases have been reported. Most cases of tricuspid valve calcification had a congenital disorder with high pressure in the right ventricle. Case presentation We report a rare case of a 71-year-old Japanese woman who presented with chest discomfort, and was found to have a double chambered right ventricle with severe calcification of the tricuspid valve. This abnormality was found by echocardiography, and the diagnosis was confirmed by multislice cardiac computerized tomography, cardiac magnetic resonance imaging, and cardiac catheterization. Our patient rejected surgical repair, and medical therapy with carvedilol was effective to reduce her symptoms. Conclusion Calcification of the tricuspid valve is extremely rare, and considered to be due to high pressure in the right ventricle. To the best of our knowledge, there are no other reported cases of this combination of double chambered right ventricle and calcification of the tricuspid valve.

Abstract
The aim of this study was to investigate a rare subset of adult patients with double-chambered right ventricle, pertaining to clinical presentation, rhythm disturbances, surgical approach, and results of surgical repair. A retrospective review of our records revealed that 14 adults had undergone surgical repair of double-chambered right ventricle from 1990 to 2010. Their median age was 25.5 years, and their median weight was 50 kg. Patients presented with various symptoms, the most common being dyspnea on exertion. The mean systolic pressure gradient across the obstruction was 69.8 ± 23.1 mm Hg. The most common associated anomaly was ventricular septal defect. Significant rhythm disturbances were present in 4 patients. Transatrial repair was undertaken in 5 patients, a combined transatrial and transpulmonary approach was used in 4, and a right ventriculotomy in 5. There was no mortality at a median follow-up of 5.1 years. A mild right ventricular outflow tract gradient was noted in 2 patients. Medical management was required for rhythm disturbances in 2 patients. Double-chambered right ventricle can present in adulthood, often with vague symptoms. The midterm results of surgical correction are satisfactory. Long-term follow-up is necessary to detect late arrhythmias.

Abstract
BACKGROUND/AIMS This study evaluated the clinical features of double-chambered right ventricle (DCRV) in adults. Most cases of DCRV are diagnosed and treated during childhood. Consequently, very few reports include cases in which its clinical characteristics are evident in adults. METHODS We reviewed the clinical data for 10 adult patients (age > or = 18 years) with DCRV. RESULTS Electrocardiogram showed right ventricular hypertrophy in 3 DCRV patients. All cases were associated with ventricular septal defect (VSD; 7 for perimembranous, 2 for muscular outlet, and 1 for the subarterial type). Surgical correction was done for 7 DCRV patients all of whom survived operations. Their follow-up echocardiogram showed the pressure gradient in their right ventricle was significantly decreased from 69.4 +/- 17.2 mmHg preoperatively to 10.2 +/- 5.0 mmHg postoperatively (p < 0.05). In the short-term follow-up, there was no significant increase in the pressure gradient in the right ventricle. CONCLUSIONS There are lots of cases of DCRV that are not diagnosed accurately in adults. In our experience, all DCRV cases had VSD and surgical correction of these cases showed excellent results. Therefore, accurate diagnosis of DCRV is necessary so that DCRV is not overlooked and operations are enabled within an appropriate time.

Abstract
We report the case of a 55-year-old woman who was admitted for exertional chest pain with dyspnea. The patient was diagnosed with an isolated double-chambered right ventricle (DCRV) without associated congenital anomalies. Most cases of DCRV are diagnosed at a young age and commonly associated with VSD; isolated DCRV in adults is extremely rare.
