Spontaneous interatrial hematoma is a rare clinical entity leading to the obliteration of the left atrial cavity and causing haemodynamic compromise, necessitating immediate surgical intervention. Herein, we report a patient with acute chest pain with normal coronaries and echocardiographic evidence of left atrial mass. The investigations revealed the mass to be a thrombus rather than tumour. The patient underwent surgery to remove a large thrombus completely enclosed within the interatrial septum. The septum was then repaired using a pericardial patch. No apparent etiological factor was found. Spontaneous atrial wall dissection should be considered in the differential diagnosis of acute chest pain.

Objectives: We aimed to develop a streamlined algorithm for the management of intracoronary calcification that includes guidance on intracoronary imaging and the appropriate selection of atherectomy devices.

Methods: National experts representing both the National Heart Center (NHC) and the Saudi Arabian Cardiac Interventional Society (SACIS) met to develop a consensus document on the assessment and management of intracoronary calcification in Saudi Arabia. The nominal group technique was utilized; a number of statements on the assessment and management of coronary artery calcification were developed based on a systematic review of the literature. The authors discussed the developed statements until a consensus was reached.

Results: Twenty statements were discussed and agreed upon. Invasive and non-invasive imaging modalities in the assessment of coronary artery calcification, and management of intracoronary calcification using calcium ablation techniques, excimer laser coronary atherectomy, ballon-based techniques, and shockwave lithotripsy; were all thoroughly discussed in light of scientific evidence and the experts' clinical practice.

Conclusions: We present a national consensus on the assessment and the multifaceted management of intracoronary calcification in Saudi Arabia.

Objectives: In this study, we investigated whether cardioprotective properties of sevoflurane were expressed in patients with rheumatic heart disease undergoing heart valve surgery under cardiopulmonary bypass (CPB).

Methods: Fifty patients with rheumatic heart disease undergoing heart valve surgery under CPB were randomly assigned to receive total anesthesia with sevoflurane or propofol during surgery. Except for this, anesthetic and surgical management was the same in all patients. The primary outcomes were postoperative high-sensitive cardiac troponin T (hs-cTnT) and creatine kinase-myocardial band (CK-MB) release. The secondary outcomes were hemodynamic events and short-term clinical outcomes (within 30 days after surgery).

Results: The plasma concentrations of hs-cTnT at 24-hour and CK-MB from 6-hour to 48-hour in the sevoflurane group were lower than those in the control group (the propofol group). After aortic unclamping, heartbeat recovery was faster and the rate of sinus rhythm was higher in the sevoflurane group than in the control group. Moreover, a lower proportion of pacemaker use and the need for intraoperative and postoperative inotropes were also found in the sevoflurane group. Nevertheless, there were no differences between the two groups regarding short-term clinical outcomes (durations of mechanical ventilation, intensive care unit stay, hospital stay, morbidity, and mortality rates).

Conclusion: Sevoflurane administered during the entire anesthetic procedure had a myocardial protective effect with less evidence of myocardial damage in the first 48-hour postoperatively but short-term clinical outcomes were not significantly different when compared with the control group in patients with rheumatic heart disease undergoing heart valve surgery under CPB.

Objective: To analyze and compare various cardiovascular disease risk scores in Western Indian patients undergoing Coronary angiogram (CAG).

Methods: In this prospective cross-sectional study, 1213 patients who underwent conventional coronary angiography; clinical risk profile and biochemical investigations were evaluated prior to undergoing CAG. Apart from the demographic information, 10-year absolute risk of having a major cardiovascular event (cardiovascular death, myocardial infarction or stroke) was calculated for each patient using various available Traditional Risk Scores (TRS). The population was divided in low, intermediate and high-risk categories for each of these scores.

Results: Traditional cardiovascular risk factors like hypertension (41.8%) and diabetes mellitus-II (26.9%) were the two most prevalent risk factors in our study population. A higher risk value for all these TRS was more likely to be associated with obstructive coronary artery disease (OCAD) on CAG. Patients with high risk (≥20% for 10-year) QRESEARCH (QRISK3) score category had higher number of patients with obstructive CAD (49.6%) as compared to high risk category of risk score for those with high Global Registry of Acute Coronary Events (GRACE) score (46.6%) or risk Framingham (FRS CHD) score (29.2%) and risk atherosclerotic cardiovascular disease (ASCVD) score (30.1%) (P < 0.0001). A higher TRS was more likely to be associated with obstructive CAD, with the highest predictability being with QRISK3 (QRISK3 score 60.9%, GRACE score 54.9%, FRS-CHD score 34% and ASCVD score 42.1% respectively; P < 0.0001). A substantial study population (27.4%) cannot be identified using any of these TRS and hence a need of indigenous or modified risk scores is proposed.

Conclusion: QRISK3 score was most efficacious for predicting obstructive CAD in our Indian study population on CAG. A higher risk score also correlated with the number of vessels involved on coronary angiogram. A substantial obstructive CAD patient could not be identified using traditional risk scores hence need for an indigenous or modified score.

Objectives: Coronary angiography is a procedure performed during cardiac catheterization to define the coronary anatomy and determine the extent of coronary artery disease (CAD). The use of a cheap, relatively available tool like an ultrasound machine to assist in vascular access might reduce the risks associated with blind access. This study aimed to explore the efficacy and associated complications of ultrasound-guided coronary artery catheterization.

Methods: This systematic review of randomized controlled trials (RCTs) was conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-Analysis (PRISMA) and was registered in PROSPERO (CRD42022365518). A systematic search was performed for all published studies without language or country restrictions and all study variables were extracted into prefilled sheets by two independent reviewers.

Results: This meta-analysis identified 10 RCTs. The results confirmed statistically significantly reductions of total complications (RR = 0.53, 95% CI 0.39-0.72, P < .001), and hematoma >5 cm formation (RR = 0.43, 95% CI 0.25-0.75, P = 0.003) in patients who underwent ultrasound-guided coronary artery catheterization.

Conclusion: Ultrasound with catheterization, as opposed to landmark-based catheterization, significantly improved the peri-catheterization operative outcomes, providing evidence for further research to be conducted and consideration for its implementation within the medical setting.

Cardiac strangulation is a rare but potentially lethal complication of epicardial pacemaker insertion. We present the case of a 9-year-old girl who was identified as having cardiac strangulation on routine follow-up for an epicardial pacemaker inserted on day 1 of life for congenital complete heart block (CCHB). The potential clinical presentations and risk factors for pacemaker strangulation are then discussed.

Introduction: Cardiopulmonary resuscitation training in Malaysia has evolved from traditional to modern approaches, embracing technology for better outcomes. Smartphone-based training apps offer interactive learning with simulations and real-time feedback, improving cardiopulmonary resuscitation skills anytime, anywhere. This study evaluates the effectiveness of the smart-cardiopulmonary resuscitation application for healthcare practitioners.

Methods: This randomized controlled pilot study was conducted with 30 healthcare practitioners at the University of Malaysia Sabah. Participants underwent a Cardiopulmonary Resuscitation Practical formal educational training program, and data were collected using a Basic Life Support questionnaire and skills assessment checklist sourced from the American Heart Association (2020). Data analysis was conducted utilizing repeated analysis of variance and the Cochran 'Q' test supported by Statistical Package for the Social Sciences statistical software.

Result: The control and intervention groups showed improved knowledge and skills from pre-to post-cardiopulmonary resuscitation courses; a significant increase was observed in the intervention group compared to the control group. The F-test indicated a significant time-group effect (F-stat (df) = 16.14 (2), p = 0.01). Cochran's 'Q' test also revealed significant changes in the proportion of healthcare practitioners passing their skills assessments over time (2 = 14.90, control 01).

Conclusion: The smart-cardiopulmonary resuscitation application is convenient for refreshing cardiopulmonary resuscitation skills and maintaining proficiency. While it doesn't replace formal cardiopulmonary resuscitation courses, it saves healthcare practitioners and the community time and money. Both groups showed improved cardiopulmonary resuscitation knowledge and skills, with the intervention group using the smart-cardiopulmonary resuscitation application showing higher success rates after two months. Adopting smartphone-based cardiopulmonary resuscitation training with comprehensive content is recommended.

Identifying the infarct-related artery (IRA) in a non-ST-segment-elevation acute myocardial infarction (NSTEMI) can be very challenging, particularly in a hospital that cannot perform intracoronary imaging due to certain limitations. This is because, by angiography, most patients present with multivessel coronary artery disease (CAD), diffuse disease, or non-significant CAD. We present a case of a 60-year-old female patient presented with substernal chest pain and palpitations of 6 h duration. The first hospital contact 12-lead electrocardiogram (ECG) showed ventricular tachycardia (VT) with unstable hemodynamics, after stabilization patient was transported to the catheterization laboratory for immediate percutaneous coronary intervention (PCI). With a clue of VT morphology, post-converted ECG, and coronary angiography, the patient successfully underwent PCI in the left circumflex artery.
