- J Interv Cardiol 2016 Sep 26JI
- CONCLUSIONS: PPVI may be associated with transient VT in the acute peri-procedural period. Patients of smaller size may be more susceptible. All patients were managed conservatively and none of the patients had a recurrence, which is suggestive of a transient phenomenon.

A 13-year-old girl had a witnessed loss of consciousness after a scuffle with another student at school and was found in ventricular fibrillation at the time of arrival of emergency medical services personnel. The patient was successfully defibrillated in the field and was transported to the emergency department as a presumed "traumatic arrest". The patient's initial electrocardiogram was remarkable for a prolonged QT interval, and it was discovered that multiple family members had died of cardiac events as young adults. Genetic testing subsequently revealed a mutation in the RYR2 gene, which is implicated in catecholaminergic polymorphic ventricular tachycardia.

Objective: To observe the long-term prognosis and related outcome predictors for hypertrophic obstructive cadiomyopathy (HOCM) patients underwent alcohol septal ablation (ASA). Methods: A total of 227 consecutive patients(age: (47.8±11.7) years) treated by ASA from September 2005 to December 2013 in our hospital were included and followed-up for 4.42 years(range: ( 1.17-9.93) years). Follow up rate is 97.4%(221/227). General information, medical history, data of ASA and complications during hospitalization were obtained through access to medical records of patients. The patients were followed up by telephone or outpatient visit. Results: During hospitalization period, one patient died due to retroperitoneal hemorrhage, two ventricular fibrillation events and two sustained ventricular tachycardia events occurred and all patients were successfully recovered after electrical cardioversion (defibrillation). Four cardiac tamponade events occurred, 35.7% (81/227) patients experienced temporary three degree atrioventricular block. Five delayed three degree atrioventricular block evens occurred. During follow up, the percent of NYHA Ⅲ/Ⅳclass was significantly reduced (10.1%(23/227)vs. 74.9%(170/227), P=0.000). The incidence of syncope and amaurosis fugax was also reduced(2.6% (6/227) vs. 39.2% (89/227), P=0.035). A total of six patients died (4 cardiac death), one patient complicating atrial fibrillation died of cerebral embolism, one patient died of rectal cancer. One cerebral hemorrhage occurred. Six patients developed-new onset atrial fibrillation. One patient received permanent pacemaker implantation. Eight patients received surgical myocardial resection. Three patients underwent repeated ASA. Survival free of all-cause mortality at 1, 5, 9 year was 100%, 96%, 96%, respectively. Survival free of cardiac death and NYHA Ⅲ/Ⅳclass at 1, 5, 9 year was 100%, 86%, 70%, respectively. Cox-regression analysis showed that residual left ventricular outflow tract gradient after ablation(HR=1.027, 95%CI 1.006-1.048, P=0.010), less volume of injected ethanol(HR=0.596, 95%CI 0.398-0.892, P=0.012), presence of temporary complete atrioventricular block (HR=0.332, 95%CI 0.124-0.886, P=0.028)were independent predictors of cardiac death and NYHA Ⅲ/Ⅳ. Conclusion: Our study results suggest that ASA could significantly improve symptoms and outcome in patients with HOCM. Residual left ventricular outflow tract gradient after ablation, less volume of injected ethanol, presence of temporary complete atrioventricular block during ASA are independent predictors of cardiac death and NYHA Ⅲ/Ⅳ.

Sudden cardiac death (SCD) is still among the leading causes of death in women and men, accounting for over 50% of all fatal cardiovascular events in the United States. Two arrhythmia mechanisms of SCD can be distinguished as follows: shockable rhythms (ventricular fibrillation and pulseless ventricular tachycardia) and non-shockable rhythms including asystole or pulseless electrical activity. The overall prognosis of cardiac arrest due to shockable rhythms is significantly better. While the majority of SCDs is attributed to coronary artery disease or other structural heart disease, no obvious cause can be identified in 5% of all events, and those events are labeled as sudden unexplained deaths (SUD). Those unexplained events are typically caused by rare hereditary electrical disorders or arrhythmogenic cardiomyopathies. A systematic approach to the diagnosis of cardiac arrest followed by tailored therapy based on etiology has emerged in the last 10-15 years, with significant changes of medical practice and risk management of cardiac arrest victims. The aim of this review is to summarize our contemporary understanding of SCD/SUD in adults and to discuss current concepts of management and secondary prevention in cardiac arrest victims. A full discussion of the topic of primary prevention of SCD is beyond the scope of this article.

A 77-year-old female was referred for evaluation of an episode of syncope while eating breakfast. There was no history of fall, syncope, prodrome, dyspnoea, chest discomfort or palpitations. Medical history was notable for hyperlipidaemia and treated hypertension. Blood pressure was 140/90 mm Hg, pulse 85 beats per minute (BPM). No murmurs were present on cardiac examination. ECG revealed normal sinus rhythm with left ventricular (LV) hypertrophy (see online supplementary figure S1). Holter monitor demonstrated rare premature ventricular complexes (<1% of beats), without heart block or ventricular tachycardia. Transthoracic echocardiogram is shown in figure 1.

- Ventricular-Arterial Function and Coupling in the Adult Fontan Circulation. [Journal Article]
- J Am Heart Assoc 2016; 5(9)JA
- CONCLUSIONS: Adult Fontan patients have contractile and diastolic dysfunction with normal afterload, impaired VA coupling, and reduced ventricular efficiency with heightened sensitivity to heart rate. Maintenance of CI is dependent on lower afterload, eccentric remodeling, and relative preservation of diastolic function. These data contribute to our understanding of circulatory physiology in adult Fontan patients.
