“…We have not found any previous reports on the coexistence of LD and PDA. Muscular diverticulum is generally found at the apical region and is seldom seen at the basal region [ 2 , 3 ]. Most left ventricular diverticula are asymptomatic.…”

“…Some of the important diagnostic characteristics of LD, noted in a previously published review [ 3 ], are summarized below and are helpful to exclude post-infarct aneurysm and takotsubo: (1) Examining synchronous contractility, normal ventricular wall motion and normal ejection fraction is one important diagnostic characteristic. Muscular-type LD can contract synchronously with the ventricle and can be identified relatively easily.…”

BackgroundLeft-ventricular diverticulum (LD) associated with patent ductus arteriosus (PDA) is extremely rare. We have not found any previous reports of the coexistence of these two malformations. Such an association presenting with chest pain mimicking an infarct aneurysm with angina or a takotsubo cardiomyopathy with chest pain is difficult to differentiate clinically. Here, we discuss several diseases characterized by left-ventricular apical protrusion with chest pain to familiarize clinicians with the differential diagnosis of these diseases.Case presentationA 58-year-old woman was referred to our hospital because of complaints of chest pain and dyspnoea, mainly on exertion. An electrocardiograph on admission showed a q-wave in lead I, a Q-wave in lead aVL, and an abnormal T-wave in the limb leads and leads V4 to V6. A transthoracic echocardiograph revealed a PDA and a protrusion arising from the apex of the left ventricle. The diagnosis on admission was PDA and coronary artery disease with infarct aneurysm. To evaluate the source of the chest pain, further evaluations were performed. Coronary angiography showed no abnormal findings. Left ventriculography confirmed the presence of an apical contractile out-pouching. Based on these findings, we revised the diagnosis as LD associated with PDA. The patient underwent transcatheter occlusion of the PDA and was discharged 3 days later. Unexpectedly, transcatheter occlusion resolved the paroxysmal chest pain in this case.ConclusionThis is the first case report of LD combined with PDA. PDA should be considered in the list of differential diagnosis of chest pain. Several diseases characterized by left-ventricular apical protrusion with chest pain, such as LD, infarct aneurysm and takotsubo cardiomyopathy, can be misdiagnosed as one another. Therefore, it is important to familiarize clinicians with the differential diagnosis of these diseases.

“…And most of the CVD cases were isolated diverticulum (69.1%), without any other cardiac malformations. [ 4 ] The association between its location and patient's outcome has not been completely exhibited and most patients stay free of any complications throughout their lifetime. [ 5 ]…”

“…The subaortic area (48.0%), cardiac apex (24.0%), and left-ventricular posterior wall (20.0%) were the most common locations of CVD. [ 4 ] And according to the structural characteristics of the wall, CVD can be classified into 2 types: muscular and fibrous. [ 8 ] Most muscular type is found in the cardiac apex (73.9%) while most fibrous type is located at the subaortic area (82.4%).…”

Rationale:Congenital ventricular diverticulum is a rare cardiac malformation with a prevalence of about 0.26% in unselected adult patients during other diagnostic procedures. Ventricular arrhythmia originating from outflow tract diverticulum is even rarer and its etiology, epidemiology and proper treatment still remain controversial.Patient concerns:We present 2 cases of isolated outflow tract diverticulum incidentally revealed by cardiac angiography during catheter ablation for ventricular arrhythmia. The diverticulums in both cases were found to be the origins of the arrhythmia.Diagnoses:The 2 patients were both diagnosed with ventricular arrhythmia originating from the outflow tract diverticulum.Interventions:Catheter ablation was successfully performed for case 1 while a conservative observation strategy was chosen for case 2.Outcomes:Case 1 has been asymptomatic and free of premature ventricular contractions (PVCs) and both patients have no cardiac event during observational follow-up for 12 months.Lessons:For ventricular arrhythmia originating from outflow tract diverticulum, catheter ablation may be beneficial and choosing the mouth of the diverticulum or the outflow sites around as the ablation target may be reasonable. An observational follow-up strategy for the small and asymptomatic diverticulum may also be recommended.
