Diagnosing Hypertrophic Cardiomyopathy In Athletes, Chalisa Srisukajorn, Tamonwan Megan Jirakulaporn, Helen C Huang, Erik Fung, Polakit Teekakirikul

Journal of the Hong Kong College of Cardiology

Sudden cardiac death (SCD) in a young asymptomatic individual is a devastating, unpredictable event, with a widespread impact on the public health system. Hypertrophic cardiomyopathy (HCM) is the most common form of genetic heart disease, and considered one of the leading causes of SCD affecting young and frequently asymptomatic patients. A diagnosis of HCM is challenging particularly in young athletes due to overlapping clinical phenotypesbetween pathological left ventricular hypertrophy (LVH) and exercise-induced physiological LVH. Severalinvestigational tools have been used to differentiate these two distinct entities. This review article focuses upon the diagnosis of HCM in young athletes, SCD risk assessment, …

Procedural And Clinical Outcomes Of Dedicated Venous Stents In Acute And Chronic Venous Obstruction: A Retrospective Single Center Study, Guangming Tan, Madeleine G Yan, Bryan Py Yan

Journal of the Hong Kong College of Cardiology

Background Endovenous angioplasty with stenting is an accepted treatment for patient with venous obstruction. Dedicated venous stents have been developed to improve the efficacy and safety of the venoplasty procedure. We report the procedural as well as clinical outcomes of these new generation stents in the treatment of acute and chronic venous obstruction. Method This is a single centre retrospective cohort study of patients who received venous stenting for either acute or chronic venous obstruction. Baseline demographics, procedural details, clinical outcomes including 30 day all-cause mortality, 90 day primary patency rate, and change in Villalta score were reported. Result 41 …

Recurrent Cyanotic Spells In An Octogenarian, Chin Tong Kwok, Chun Kit Wong

Journal of the Hong Kong College of Cardiology

We report rare case of an octogenarian who, after years of diagnostic delay, was found to have a patent foramen ovale, and due to an ascending aortic aneurysm that anatomically facilitated right-to-left shunt, presenting with life-threatening cyanotic attacks. The characteristic orthodeoxia-platypnea syndrome and high alveolar arterial gradient hint to the diagnosis. She was eventually treated successfully with urgent percutaneous PFO closure. Routine ordering of a transthoracic echocardiogram, without agitated saline injection under provocation maneuvers, may not be sufficient to rule out shunts.

Roles Of Exercise Treadmill Test In The Diagnosis & Risk Stratification Of Cardiac Channelopathies, Kit Chan

Journal of the Hong Kong College of Cardiology

Channelopathies are the leading causes of SCD in patients without structural heart disease. Missing the diagnosis of high-risk but concealed channelopathies could have lethal clinical consequences. However, the diagnosis of channelopathies is often challenging due to the dynamic clinical presentations and elusive ECG manifestations of these diseases. An integrated approach including clinical assessment, repeated electrocardiography, drug provocation tests, exercise stress test and genetic studies is often required for establishing the diagnosis. Pharmacological provocation tests may have limited sensitivity and may be associated with false positive results. Wide-spread use of genetic studies are limited by low yield, cost-effectiveness and availability issue. …

The Impact Of Renal Insufficiency Upon Admission On The Clinical Outcome Of Patients With Acute St-Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention, Wai Lun Kwong, Kwok Ho Yau, Eugene Sin, Kwok Keung Chan

Journal of the Hong Kong College of Cardiology

Background: Coronary artery disease is common in patients with renal insufficiency. In acute coronary syndrome, impaired renal function is present in approximately 30-40% of patients and is associated with worse prognosis. Local data regarding the risks and benefits for those patients suffering from acute ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) is scarce. We evaluated the clinical outcomes of patients suffering from STEMI with and without renal insufficiency upon admission who underwent PPCI.

Methods: From 1^st January 2009 to 30^th September 2017, all patients with STEMI treated with PPCI were identified. The primary …
