Anomalous Origin

Abstract Background Anomalous origin of a coronary artery from the pulmonary trunk is a small group of rare congenital anomalies present in up to 1% of the population. These patients, in absence of an adequate collateral supply, may present with congestive heart failure secondary to ischaemia, arrhythmia, or sudden cardiac death in up to 90% of cases within the first months of life. Case summary We present four cases diagnosed in adulthood over 10 years in two high-volume centres. The first patient presented with dyspnoea and orthopnoea. The second with chest pain and episodes of non-sustained ventricular tachycardia. The third patient presented during her third pregnancy with chest pain, palpitations, and arrhythmia (non-sustained ventricular tachycardia). The fourth patient presented with sudden cardiac death. Discussion In all cases with anomalous origin of coronary arteries, it is recommendable to consider surgical correction to avoid the progression of ischaemia, congestive heart failure, arrhythmia, and sudden death.

Diagnostic Work

Cardiac arrhythmias are more common in subjects with diabetes mellitus (DM) than in their counterparts without diabetes. Atrial fibrillation (AF) is present in 10–20% of the DM patients, but the association between DM and AF is mostly due to co-morbidities of DM patients increasing the vulnerability to AF. When type 2 DM and AF coexist, there is a substantially higher risk of cardiovascular mortality, stroke, and heart failure, which indicates screening of AF in selected patients with DM. Anticoagulant therapy either with vitamin K antagonists or non-vitamin K antagonist oral anticoagulants is recommended for DM patients with either paroxysmal or permanent AF, if not contraindicated. Palpitations, premature ventricular beats, and non-sustained ventricular tachycardia are common in patients with DM. The diagnostic work-up and treatment of these arrhythmias does not differ between the patients with or without DM. The diagnosis and treatment of sustained ventricular tachycardia, either monomorphic or polymorphic ventricular tachycardia, or resuscitated ventricular fibrillation is also similar between the patients with or without DM. The risk of sudden cardiac death is higher in DM patients with or without a diagnosed structural heart disease. Patients with diabetes and a left ventricular ejection fraction less than 30–35% should be treated with a prophylactic implantable cardioverter defibrillator according to current guidelines. Beta-blocking therapy is recommended for DM patients with left ventricular dysfunction or heart failure to prevent sudden cardiac death due to arrhythmia.

In the recent months of the COVID-19 pandemics, the cardiological society has faced a new challenge, myocardial injury by the coronavirus infection. According to statistics, 20-40% of hospitalized patients have chest pain, heart rhythm disorders, heart failure, and sudden cardiac death syndrome. This review focuses on recent studies and clinical cases related with this issue.

Cardioverter Defibrillator

A 69-year-old patient with a single chamber cardioverter defibrillator (ICD) implanted in primary prevention of sudden cardiac death (heart failure in dilated cardiomyopathy) was admitted to the hospital due to ventricular tachycardia (VT) not recognized by the ICD. After control of ICD, it was concluded that the cause of the absence of ICD intervention was the classification of arrhythmia by Wavelet as a supraventricular. Default settings have been used since the implant – (Wavelet – 70%, Onset and Stability off). The arrhythmia was within the VT detection zone. There were two possible solutions: turning Wavelet off or reducing its threshold. However, considering the absence of supraventricular arrhythmias, the Wavelet function was disabled.
