“…With the constant increase of the number of non-invasive imaging exams performed, interventricular septal aneurysms are more frequently found. They are sometimes discovered during management of complications, usually embolic events [8].…”

Management of Late-Presenting Congenital Combined Heart Defect – Bicuspid Aortic Valve and Ventricular Septal Aneurysm

2020

Objective:Rare disease Background:Bicuspid aortic valve is the most common congenital heart malformation, encountered in 1-2% of the population, while interventricular septal defect and patent ductus arteriosus are the most common congenital malformations associated with bicuspid aortic valve. Although bicuspid valve can have no clinical manifestation, patients with bicuspid valve are prone to develop vascular abnormalities. Aortic dilatation is the most common of these abnormalities, which in turn can lead to serious complications and often requires surgical treatment. Coexistence of bicuspid aortic valve and interventricular septal aneurysm is very extremely rare. Case Report:We present a very rare case of a female patient with combined congenital cardiac pathology. The patient was asymptomatic until age 68 years, and presented with nonspecific persistent cough. The diagnostic work-up for the unexplained cough showed normal function of the bicuspid valve and an ascending aorta aneurysm accompanied with interventricular septal aneurysm. The patient was referred for surgery. The diagnostic workup and the decision for surgical treatment were thoroughly discussed to determine whether it was a true or a false aneurysm. Conclusions:The presented case is an example of late diagnosis of a congenital cardiac defect. The silent evolution and the scarce clinical presentation led to incidental discovery of the pathology, which was fully assessed only by computed tomography. Although echocardiography is essential for discovering heart defects, non-invasive imaging techniques are required for detailed morphological assessment and for planning optimal surgical treatment.

“…But there are few reports that relate the development to a previous episode of infection or trauma[ 3 ]. These aneurysms can be classified as true, false and pseudo-aneurysm[ 4 ]. Those with a wide base and regular contours are true while those with a narrow base and irregular shape are termed as false.…”

“…Those with a wide base and regular contours are true while those with a narrow base and irregular shape are termed as false. A pseudo-aneurysm is complication of ischemic insults or transaortic septal myotomy[ 4 ]. Patients with interventricular septum aneurysm are often asymptomatic; if symptoms develop they are usually related to an associated complication.…”

“…Different modalities including conventional ventriculography, echocardiogram, cardiac MRI and MDCT are used for diagnosis. Morphological and functional assessment can be done with cardiac MRI or MDCT[ 4 ]. Both cardiac MRI and MDCT can also be used after surgery to determine the integrity of the patch and also to identify any residual defect but CT gives radiation exposure[ 4 ] .…”

We report a challenging case of a 81-year-old male with history of severe calcific aortic valve stenosis and aneurysmal membranous interventricular septum. The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. transcatheter aortic valve implantation (TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into the left ventricular outflow tract has not been previously reported. This case describes a successful transfemoral TAVR with an Edwards SAPIEN XT valve (Edwards Lifesciences, Irvine, CA, United States) with such anomaly.

“…Uncommonly, the aneurysm can be a source of cerebral embolism. Acquired aortic valve incompetence may result from impingement of the aneurysm on the aortic valve leaflets or from prolapse of the aortic leaflets into the aneurysm [ 12 ]. Tricuspid regurgitation or left-ventricular-to-right atrial shunt may also result [ 13 ].…”

Aneurysmal and obstructive lesions of the left ventricular outflow: evaluation on multidetector computed tomography angiography

et al. 2021

The left ventricular outflow is an anatomically complex region situated between the anterior leaflet of the mitral valve and the left ventricular aspect of the muscular and membranous interventricular septum. It gives rise to the aorta, provides support to the aortic valvular cusps, and houses important components of the conduction system. The left ventricular outflow handles high pressures and pressure variations and is subsequently affected by a variety of aetio pathological conditions. Diseases involving the left ventricular outflow can be intraluminal, mural, or extramural, and the consequent complications of the lesions can be local, locoregional, or even systemic. Appropriate evaluation requires comprehensive multimodality imaging with each modality contributing to assessment of different aspects of diagnosis, lesion characterization, local extension, prognostication for systemic complications and mortality, and the decision for the approach and type of intervention and aggressive followup in case noninterventional manage ment is decided. In this review, we briefly describe the relevant anatomy and the gamut of structural abnormalities pertaining to the left ventricular outflow on multidetector computed tomography angiography.
