BACKGROUND: Transcatheter mitral valve repair (TMVr), using MitraClip® , is a safe and effective procedure for severe mitral valve regurgitation (MR). However, the therapeutic results of MitraClip® in Qatar remain to be elucidated. A total of 25 patients (mean age 60 ± 14.5 years, 64% males) with symptomatic severe MR and prohibitive surgical risks were enrolled in this study. The procedural success rate was 92% to achieve mild residual MR. There was no periprocedural death...

Inadequate peripheral perfusion due to cardiac diseases can worsen renal function in patients with chronic kidney disease (CKD). Due to the nature of the simultaneous cardiac and renal disease, it is often difficult to determine which is the primary cause, and hence many surgeons hesitate to operate on patients with end-stage kidney disease. However, when the primary cause is cardiac related, renal function can improve after successful cardiac surgery. Here, we describe a 55-year-old female patient with CKD Stage 5 who was on maintenance hemodialysis with severe aortic stenosis (AS) and underwent surgical aortic valve replacement and recovered from dialysis-dependent kidney disease...

Acute coronary syndromes (ACSs) present most frequently with chest pain, but angina equivalents such as dyspnea, diaphoresis, and fatigue are not uncommon. Atypical presentations are especially seen in women, the elderly, and diabetics. Cardiac evaluation using a transthoracic echocardiogram is almost always done before or immediately after someone undergoes left heart catheterization for ACS. It provides information valuable information regarding wall motion, left ventricular systolic function, diastolic function, right ventricular involvement, pulmonary pressures, incidental valvular disease, pericardial fluid, or any other unsuspected abnormality...

BACKGROUND: Although respiratory support is necessary to maintain hemodynamic stability in patients undergoing major surgeries, prolonging the time of mechanical ventilation is considered a major complication following these procedures. The identification of potential factors related to this phenomenon should be identified. In the present systematic review, we first assess the pooled prevalence of prolonged mechanical ventilation (PMV) in patients undergoing coronary artery bypass grafting (CABG) surgery and also determine the main predictors for PMV by deeply reviewing the literature...

Cardiovascular diseases (CVDs) remain major causes of global mortality in the world. Genetic approaches have succeeded in the discovery of the molecular basis of an increasing number of cardiac diseases. Genome-editing strategies are one of the most effective methods for assisting therapeutic approaches. Potential therapeutic methods of correcting disease-causing mutations or of knocking out specific genes as approaches for the prevention of CVDs have gained substantial attention using genome-editing techniques...

We report an abnormal hemodynamic pressure tracing taken during pullback from the left ventricle. This report emphasizes the careful observation of hemodynamic tracing relative to continuous electrocardiographic monitoring for identifying potentially pathological vascular phenomena that may have detrimental outcomes on the clinical management of the underlying condition.

Ticagrelor is available as an oral antiplatelet agent that can bind reversibly to the adenosine diphosphate receptor P2Y12 on platelets without first having to be activated. Main side effects such as dizziness, bleeding gums, nausea in common, difficulty in speaking, fever, and change in mental status are rare. Herein, we report a patient who had seizures after the usage of ticagrelor.

A 59-year-old male dialysis patient with a history of coronary artery bypass graft surgery underwent percutaneous coronary intervention of a right coronary artery with a severely calcified lesion. While debulking calcification using a Rotablator, the driveshaft was suddenly fractured. We attempted to move a child-in-mother catheter closer and across a second floppy wire and we dilated a 2.0-mm noncompliant balloon to trap the driveshaft, which we then removed, and restarted the intervention.

INTRODUCTION: Studies from the US and Europe showed a decline in smoking among patients with acute myocardial infarction (AMI), but limited data are available from the Middle East. In this study, we describe the temporal trend in the prevalence, associated risk factors, and outcomes of smoking among patients with AMI in Qatar. MATERIALS AND METHODS: A total of 27,648 AMI patients were analyzed from the cardiology registry at Heart Hospital, Doha, Qatar. This spans from January 1991 to May 2022...

BACKGROUND: Point of care tests provide rapid information about the patient's condition, with a turnaround time of 15 min. During the COVID-19 pandemic, many such point of care tests were developed, to aid in the rapid diagnosis of SARS-Cov-2 infection. AIM: To describe and synthesize the available literature on point of care tests for diagnosis of SARS-CoV-2. METHODOLOGY: This narrative review was done through online literature search, using Google Scholar and PubMed...

BACKGROUND: Cardiovascular disease patients are more likely to be readmitted within 30 days of being discharged alive. This causes an enormous burden on health-care systems in terms of poor care of patients and misutilization of resources. AIMS AND OBJECTIVE: This study aims to find out the risk factors associated with 30-day readmission in cardiac patients at Heart Hospital, Qatar. METHODS: A total of 10,550 cardiac patients who were discharged alive within 30 days at the heart hospital in Doha, Qatar, from January 2015 and December 2019 were analyzed...

BACKGROUND: The use of rivaroxaban in patients with atrial fibrillation (AF) and chronic kidney disease (CKD) poses the risk of over- or underdosing. We aimed to compare rivaroxaban and warfarin in AF patients with moderate and severe renal impairment. METHODS: This retrospective study was conducted between 2015 and 2016 to compare the use of warfarin ( n = 164) and rivaroxaban ( n = 149) in patients with AF and moderate or severe CKD. The study outcomes were survival, stroke, and major bleeding events...

BACKGROUND: Clinical equipoise between a percutaneous coronary intervention (PCI) and coronary artery bypass grafting surgery (CABG) in the treatment of complex coronary artery disease (CAD), including unprotected left main coronary artery (LMCA) and/or three-vessel disease (3VD), remains debatable. METHODS: A retrospective analysis of an unselected cohort undergoing contemporary PCI versus CABG at a large center in 2015. Patients who received nonemergent treatment of unprotected LMCA and/or 3VD were included...

A 67-year-old man with inferior wall ST-segment elevation myocardial infarction underwent Impella-assisted percutaneous coronary intervention complicated by unilateral left-sided pulmonary edema and cardiogenic shock due to severe mitral valve regurgitation. Surgery was deferred due to hemodynamic instability and a high risk of mortality, so he underwent a MitraClip procedure. Mitral regurgitation (MR) is a catastrophic mechanical complication of myocardial infarction that leads to the development of pulmonary edema, cardiogenic shock, and death...

The authors present a case of a 54-year-old male patient with a history of shortness of breath and orthopnea. The echocardiogram showed an ejection fraction (EF) of 35%-40%. Diagnosis of hyperthyroidism was missed initially although the patient had bilateral exophthalmos and thyroid function tests suggesting it. Medical treatment of the hyperthyroid state reversed the cardiomyopathy within 6 months of treatment. Repeated echocardiograms after hyperthyroidism treatment showed a normalized EF.

Mycotic pseudoaneurysms (PA) are an infrequent complication of infective endocarditis (IE). However, due to advanced imaging modality and early therapy, this complication has been seen less frequently in the past few years. The reported incidence is 5%-15% of the patients, with the most common site being intracranial vessels (up to 65%), followed by abdominal and then peripheral vessels. We describe a young patient with a bicuspid aortic valve complicated by IE, who developed a giant mycotic PA. This was treated with a cover stent of the aneurysmal segment, which was complicated by distal stent migration and eventually managed with bypass surgery...
