“…Eighteen percent of all patients had to be rehospitalized during the follow-up period, 73% of them for cardiovascular reasons. If one focuses only on symptoms known to be frequently related to LVA and LVD (embolic events, rhythm disturbances, syncope) [2,10,11,12,13], almost 30% of our study population complained of 1 or more symptoms out of these 3 categories during the follow-up period. The presence of LVD significantly increases the risk of embolic events (p = 0.04).…”

Objectives: We sought to investigate the prevalence and clinical outcome of congenital left ventricular aneurysms (LVAs) and diverticula (LVD) in a large adult population. Methods: We retrospectively studied the left ventricular angiograms of 12,271 consecutive patients undergoing cardiac catheterization at our institution and analyzed the medical records of the patients. Results: The overall prevalence of LVA/LVD was 0.76% (94 patients): there were 42 patients with LVA (0.34%) and 52 patients with LVD (0.42%). Men were more likely to have LVA (62 vs. 38%), and women were more likely to have LVD (75 vs. 25%; p = 0.001 for both). The mean time of follow-up was 56 ± 6 months and was focused on clinical events, rehospitalization and survival. Mortality was 6% with no cardiac death. Patients with LVD were significantly more likely to have embolic events (p = 0.04). Patients with LVA and LVD were more likely to have rhythm disturbances compared with controls (p = 0.01 for both). Incidence of syncope was not different in both groups (p = 0.4 and 0.12, respectively). There was no reported incidence of rupture. Conclusion: This large single-center study suggests that the prevalence of LVA/LVD in adults is up to 20-fold higher than previously reported. One third of the affected patients in our series had nonfatal cardiovascular events during follow-up, with a predominance of embolic events in the LVD group.

“…Symptomatic patients usually suffer from ventricular arrhythmias, ranging from occasional ventricular premature beats to sudden cardiac death. Patients with documented ventricular tachycardia show right bundle branch block morphology according to the left ventricular origin of the arrhythmogenic substrate [6, 23, 24, 25, 27, 45]. Frequent causes of complaints are supraventricular rhythm disturbances, e.g.…”

“…Depending on its location, blood supply of a diverticulum is derived from the right or left coronary artery, or both, with a normal venous return [18]. Congenital aneurysms mostly show connective tissue with reticulin fibers (Masson staining) and only few unorganized muscular fibers with various degrees of vacuolization [45]. The internal surface is covered with simple endothelium (CD31 and CD34 staining) [2, 18, 25, 36 ](fig.…”

“…Therefore, treatment modalities are determined by the clinical presentation and findings of the individual patient. Many authors [2, 3, 12, 13, 18, 20, 21, 25, 30, 31, 36, 43, 45, 48, 53, 54, 57] recommend surgery even in asymptomatic patients in order to prevent serious and potentially lethal complications, e.g. spontaneous rupture, which was reported in 15 of the 411 patients published in the literature (3.7%).…”

Congenital Left Ventricular Aneurysms and Diverticula: Definition, Pathophysiology, Clinical Relevance and Treatment

A congenital left ventricular aneurysm or diverticulum is a rare cardiac malformation; 411 cases have been reported since its first description in 1816, and other cardiac, vascular or thoraco-abdominal abnormalities have been shown in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. Diagnosis can be made after exclusion of coronary artery disease, local or systemic inflammation or traumatic causes as well as cardiomyopathies. Clinically, most congenital left ventricular aneurysms and diverticula are asymptomatic or may cause systemic embolization, heart failure, valvular regurgitation, ventricular wall rupture, ventricular tachycardia or sudden cardiac death. Diagnosis is established by imaging studies such as echocardiography, magnetic resonance imaging or left ventricular angiography, visualizing the structural changes and accompanying abnormalities. Mode of treatment has to be individually tailored and depends on clinical presentation, accompanying abnormalities and possible complications; treatment options include surgical resection especially in symptomatic patients, anticoagulation after systemic embolization, radiofrequency ablation or implantation of an implantable cardioverter defibrillator in case of symptomatic ventricular tachycardia, occasionally combined with class I or III antiarrhythmic drugs.

“…6 If not associated with the latter, as was seen in our case, they may present with non-specific abnormalities on resting electrocardiogram, including atrial ectopic beats, ST-T wave changes, and arrhythmias. 7 A fibrous left ventricular diverticulum is pathologically characterised by the presence of only fibrous tissue and no myocardial wall component. These are found to be non-contractile on echocardiography and more prone to rupture in comparison with the other type.…”

Left ventricular diverticulum is a rare cardiac abnormality characterised by focal protrusion of the ventricular wall containing all the three layers with synchronous contractility. They have been described more commonly in paediatric patients and may be seen associated with congenital midline thoracoabdominal abnormalities. There are few reports of left ventricular diverticulum in cases of patent ductus arteriosus and coarctation with subaortic diverticula in the bicuspid aortic valve. Here, we report a case of left ventricular diverticulum in association with bicuspid aortic valve and pseudocoarctation in a 53-year-old female patient with a pertinent review of the literature.
