- Epicardial Ventricular Tachycardia in Ischemic Cardiomyopathy: Prevalence, Electrophysiological Characteristics, and Long-term Ablation Outcomes. [Journal Article]
- JCJ Cardiovasc Electrophysiol 2018 Sep 19
- CONCLUSIONS: The presence of critical EPI substrate responsible for VT can be demonstrated in at least 14% of patients with ICM. The majority of EPI critical ablation sites are distributed opposite to the ENDO bipolar scar area and catheter ablation is effective in achieving long-term arrhythmia control.

- Atrioventricular accessory pathways in 89 dogs: Clinical features and outcome after radiofrequency catheter ablation. [Journal Article]
- JVJ Vet Intern Med 2018 Sep 14
- CONCLUSIONS: Accessory pathways are challenging to recognize in dogs because of nonspecific clinical signs, frequency of concealed APs that show no evidence of their presence during sinus rhythm, and intermittent occurrence of tachyarrhythmias resulting from APs. Tachycardia-induced cardiomyopathy commonly occurs with AP-mediated tachycardias and should be considered in any dog presenting with a dilated cardiomyopathic phenotype because of its good long-term prognosis with rhythm control. Radiofrequency catheter ablation is a highly effective method for eliminating AP conduction and providing long-term resolution.
- Possibility of venoarterial extracorporeal membranous oxygenator being a bridging therapy for hemodynamic deterioration of pulmonary tumor thrombotic microangiopathy prior to initiating chemotherapy: A case report. [Journal Article]
- MMedicine (Baltimore) 2018; 97(37):e12169
- CONCLUSIONS: VA-ECMO rapidly stabilized the hemodynamic status of this patient with PTTM, and may thus be a possible bridging therapy for deterioration of PTTM prior to initiating imatinib.

A 26-year-old woman of Cap Verdean origin was admitted to emergency unit with chest pain and dyspnea. Because of sinus tachycardia without any other electrocardiogram abnormalities, high NT-pro BNP level, and weakly positive cardiac troponin I and D-dimer levels, an aortic and pulmonary non ECG-gated CT-angiography was performed that excluded pulmonary embolism and aortic dissection. Transthoracic echocardiography (TTE) showed a contained rupture of the non-coronary sinus of Valsalva aneurysm sized 23 to 24mm into the right atrium. According to the high rupture risk, patient had been immediately transferred in a cardiologic surgical center where transesophageal echocardiography (TEE) and thoracic angiography ECG-gated Multiple Detector Computerized Tomography (ECG-gated MDCT) reinforced the diagnosis. Patient underwent surgical repair resection of the aneurysmal sac, which was described as "tissue paper thin" and at risk for impending rupture, without evidence of communication between the aorta and the right atrium. Anatomopathological examination described a thick sclerotic and oedematous aneurysm wall without inflammation, and bacteriological examination was negative. It is a rare case of contained rupture of the congenital non-coronary sinus of Valsalva aneurysm into the right atrium (Type IV of Sakakibara classification), with a high rupture risk. This case shows that the use ECG-gated-MDCT is more appropriate when aortic dissection is suspected, allowing a detailed analysis of aorta, especially the proximal portion which is more susceptible to motion artifacts.

A 23-year-old woman followed at another medical centre for congenital heart disease (CHD) presented to our emergency clinic with 3 weeks of bilateral pleuritic chest pain. She returned from holiday in Greece 6 weeks earlier where a tattoo and nasal piercing had been performed. There was no history of night sweats or fever.Her temperature was 37.5°C, heart rate 120 beats/min, oxygen saturations 94% on room air and blood pressure 110/74. Her chest was clear and there was systolic murmur on auscultation. The chest radiograph showed peripheral bilateral lower zone atelectasis. The ECG demonstrated sinus tachycardia. The haemoglobin was 11.2 g/dL, white cell count 10.18×109/L, C-reactive protein 67 mg/L (normal <5 mg/L) and D dimer=430 ng/mL (normal <230 ng/mL).A pulmonary embolus was suspected and a CT pulmonary angiogram was performed (figure 1).
- Inappropriate ICD shock due to hot tub-induced external electrical interference. [Journal Article]
- JEJ Electrocardiol 2018 Sep - Oct; 51(5):852-855
- CONCLUSIONS: Electrical interference due to external sources such as hot tub engines may occur and produce an inappropriate detection and ICD shock. Precaution and patient education is warranted.

Algorithms used for the differential diagnosis of wide QRS complex tachycardia are extremely important in clinical practice, but they have limitations and should be applied with caution. We describe a case of a patient with positive serology for Chagas disease and normal echocardiogram who presented an episode of wide QRS complex tachycardia. It was initially diagnosed as sustained ventricular tachycardia using the Brugada and Vereckei algorithms and it was sent to the reference service for the implant of a cardioverter defibrillator. However, the clinical history, electrocardiogram in sinus rhythm and the electrophysiological study were fundamental to the correct diagnosis and treatment of a posterolateral atrioventricular accessory pathway.
- Extended ECG monitoring with an implantable loop recorder in patients with cryptogenic stroke: time schedule, reasons for explantation and incidental findings (results from the TRACK-AF trial). [Journal Article]
- CRClin Res Cardiol 2018 Aug 22
- CONCLUSIONS: The present study revealed a significant number of ECG findings during continued ECG monitoring for AF in patients with cryptogenic stroke. Apart from AF (17.5% during the first 1.5 years), other clinical relevant arrhythmias requiring, e.g., pacemaker implantations, were observed. With respect to these findings, we recommend to extend ILR monitoring to the end of battery life. However, acceptance of continued ECG monitoring until battery depletion was poor; in 71 patients (64%), the ILR were explanted before the end of battery life.

A 50-year-old woman visited the emergency department with a high fever due to pneumonia. Incessant monomorphic ventricular tachycardia occurred and was terminated by intravenous lidocaine. Her ECG during sinus rhythm demonstrated ST segment elevation suggestive of Brugada syndrome (BS). An intensive examination could not detect any structural disease, and typical coved-type ST elevation was unmasked by a pilsicainide injection leading to a diagnosis of BS. An ICD was implanted for secondary prevention of ventricular arrhythmia. The patient has been free from any recurrences of arrhythmia for 3 years.
