Congenital diveticula and aneurysm of the heart are rare and most often located at the apex of the left ventricle. They pose a significant risk for cardiac failure and arrhythmias. In contrast, nonapical diverticula of the right ventricle (RV) have a much more benign course. We present a child with Trisomy 21, atrioventricular septal defect, and large nonapical diverticulum of the RV that was neither addressed during surgery nor needed any medical treatment during 1-year follow-up.

A 40-year-old woman had been followed as an outpatient to manage chronic kidney disease secondary to autosomal dominant polycystic kidney disease (ADPKD). Atrial premature contraction was found incidentally on an electrocardiogram during her regular follow-up examination. Subsequent transthoracic echocardiography detected an abnormal structure located very close to the left ventricular outflow tract (23 mm long × 15 mm wide in diastole). The structure was finally diagnosed as congenital left ventricular diverticulum (CLVD) using transesophageal echocardiography, contrast-enhanced computed tomography, and magnetic resonance imaging...

The high spatial resolution of cardiac computed tomography (CT) and cardiac magnetic resonance (CMR) permit the diagnosis of congenital ventricular outpouchings (CVOs), including congenital ventricular diverticula (CVD), congenital ventricular aneurysms (CVA), clefts, and crypts. A unique classification has not been established, and these terms are used interchangeably with confounding terminology. Moreover, their significance is not univocal. A research was performed using PubMed on six subjects: (1) congenital left ventricular outpouchings; (2) congenital ventricular diverticulum; (3) congenital ventricular aneurysm; (4) ventricular clefts; (5) ventricular crypts; and (6) ventricular crevices...

Congenital left ventricular aneurysm or diverticulum are rare cardiac malformations described in 809 cases since the first description in 1816, being associated with other cardiac, vascular or thoraco-abdominal abnormalities in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. In an experimental study, targeted knockdown of cardiac troponin T in the chick was performed at day 3, after the heart tube has formed. Morpholino treatment of gene TNNT2 at this stage led to the development of left ventricular diverticula (LVD) in the primitive left ventricular wall...

Shamberger and Welch classify sternal malformations into four types: thoracic ectopia cordis, cervical ectopia cordis, thoraco-abdominal ectopia cordis, and cleft sternum. Cleft sternum is the most common subset, with a reported incidence of 1 in 50,000 to 100,000 live births, representing 0.15% of all anterior chest wall malformations. Acostello et al further classify cleft sternum into complete or partial (superior, medium, inferior) with a simple superior partial cleft sternum being by far the most common with an orthotopic heart, intact pericardium, and normal skin coverage...

Supravalvular aortic stenosis is an uncommon but well characterized congenital narrowing of the ascending aorta above the level of the coronary arteries. It can be a familial disorder, can occur sporadically, or can be associated with Williams syndrome. We are reporting a very rare presentation of supravalvular aortic stenosis with associated left ventricular diverticulum and cleft mitral valve. Repair consisted of resection of the ascending aorta, patch augmentation of the aortic root, and mitral valve repair...

Congenital left ventricular diverticulum (CLVD) is a rare congenital anomaly and may be associated with fatal adverse events. A previously healthy 20-year-old man collapsed as a result of sudden ventricular fibrillation (VF). Despite intractable VF, he had return of spontaneous circulation with cardiopulmonary resuscitation and subsequent introduction of venoarterial extracorporeal membrane oxygenation (ECMO). After ECMO was discontinued, cardiac magnetic resonance imaging revealed CLVD at the posterolateral wall of the left ventricle...

Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination...

Left ventricular (LV) diverticulum represents a rare and frequently asymptomatic congenital anomaly, which is incidentally discovered during routine transthoracic echocardiography. We present a case of a 66-year-old female patient who was admitted to the cardiology department due to incidental finding of a tumor-like mass associated with the posterior mitral leaflet. Preliminary echocardiographic evaluation revealed a solid structure, suspected of mitral annulus calcification or LV malignancy. However, cardiac contrast-enhanced computed tomography confirmed the presence of LV diverticulum, partially filled with calcified thrombus...

Ventricular outpouching is a rare finding in prenatal sonography and the main differential diagnoses are diverticulum, aneurysm, and pseudoaneurysm in addition to congenital cysts and clefts. The various modes of fetal presentation of congenital ventricular outpouching include an abnormal four-chamber view on fetal two-dimensional echocardiogram, fetal arrhythmia, fetal hydrops, and pericardial effusion. Left ventricular aneurysm (LVA)/nonapical diverticula are usually isolated defects. Apical diverticula are always associated with midline thoracoabdominal defects (epigastric pulsating diverticulum or large omphalocele) and other structural malformations of the heart...

A 5-day-old neonate with coarctation of the aorta, hypoplastic aortic arch, large apical muscular ventricular septal defect, and patent ductus arteriosus developed pulmonary over-circulation and systemic hypoperfusion underwent bilateral pulmonary artery banding through median sternotomy as a part of hybrid stage I palliation. At operation, left atrial diverticulum with gigantic thrombus formation at the base of the left atrial appendage was incidentally detected by intraoperative direct echocardiography, and therefore, was successfully resected with the whole thrombus inside it without use of cardiopulmonary bypass...

Pentalogy of Cantrell is a rare syndrome that is characterized by varying degrees of midline wall defects and congenital cardiac anomalies. A left ventricular diverticulum (LVD) is defined as partial ectopia cordis, can be part of the pentalogy of Cantrell, and can put the patient at risk of severe complications. Early diagnosis and ligation/resection of the LVD is important to prevent complications. We report on a case of pentalogy of Cantrell, in which a LVD was diagnosed only at 2 months of age despite preceding pre- and postnatal echocardiography...

Ventricular outpouchings include acquired abnormalities (aneurysms and pseudoaneurysms) and congenital ventricular diverticula (CVD). CVD represent rare cardiac pathologies. Although CVD is often associated with other cardiac and extracardiac congenital anomalies, it can also be incidentally observed in otherwise healthy subjects. CVD may lead to significant morbidity and even have lethal consequences. We describe a case of arrhythmogenic left ventricle (LV) apical CVD revealed by cardiac magnetic resonance imaging (CMRI) after being initially overlooked by echocardiography...

A 38-year-old man presented with exertional angina of 1-year duration. Treadmill was strongly positive. Coronary angiogram revealed a significant phasic systolic compression of the left main and the proximal left circumflex artery. Echo and MRI revealed a subaortic left ventricle diverticulum causing compression of the coronary vessels. Before the planned surgery, the patient had sudden deterioration with cardiogenic shock and could not be saved.

Congenital left ventricular diverticulum is a rare cardiac anomaly. During the newborn period, symptomatic patients are diagnosed with heart failure findings. We present a 23-day-old male newborn with congenital left ventricular diverticulum diagnosed during fetal echocardiographic examination. After the birth, the patient had heart failure symptoms and his echocardiographic examination showed low cardiac ejection fraction. Diverticulum was operated with endoventricular circular patch plasty (DOR) technique, and after, cardiopulmonary bypass venoarterial extracorporeal membrane oxygenation (ECMO) support was performed because of low cardiac output syndrome...
