• Unroofed CS is a rare cause of atrial-level shunting and right heart dilatation. • Unroofed CS is commonly diagnosed in adulthood. • TTE is the primary modality to recognize and diagnose unroofed CS. • CCT and/or magnetic resonance imaging should be done as complementary studies before CS repair.

Transient left bundle branch block occurring during a nuclear stress test in the setting of myocardial bridging is a relatively rare finding. We report a case of a 75-year-old male who presented with typical stable angina. Serial troponins were negative, and the electrocardiogram revealed normal sinus rhythm with left ventricular hypertrophy and T-wave inversions in the lateral leads. The nuclear stress test was non-ischemic but showed a transient left bundle branch block associated with chest pain and shortness of breath that occurred right after the administration of regadenoson...

We present a case of a patient with inferior myocardial infarction (MI) and anomalous left main artery originating from the right coronary sinus. The left main artery and right coronary artery originated from the right coronary sinus but with separate ostia. The patient underwent revascularization of the right coronary artery with balloon angioplasty and a drug-eluting stent. Despite being rare, these anomalies can be life-threatening depending on the course of the artery, and when atherosclerotic disease is present, a revascularization strategy can be challenging...

The coronary sinus reducer (CSR) is an emerging medical device for treating patients with refractory angina, often associated with myocardial ischemia. Patients implanted with CSR have shown positive outcomes, but the underlying mechanisms are unclear. This study sought to understand the mechanisms of CSR by investigating its effects on coronary microcirculation hemodynamics that may help explain the therapy's efficacy. We applied a validated computer model of the coronary microcirculation to investigate how CSR affects hemodynamics under different degrees of coronary artery stenosis...

Aortic stenosis (AS) and hypertrophic cardiomyopathy (HCM) are distinct disorders leading to left ventricular hypertrophy (LVH), but whether cardiac metabolism substantially differs between these in humans remains to be elucidated. We undertook an invasive (aortic root, coronary sinus) metabolic profiling in patients with severe AS and HCM in comparison with non-LVH controls to investigate cardiac fuel selection and metabolic remodeling. These patients were assessed under different physiological states (at rest, during stress induced by pacing)...

BACKGROUND: Coronary artery obstruction after percutaneous aortic replacement is a complication with high short-term mortality secondary to the lack of timely treatment. There are various predictors of coronary obstruction prior to valve placement such as the distance from the ostia, the degree of calcification, the distance from the sinuses; In such a situation some measures must be taken to prevent and treat coronary obstruction. CASE PRESENTATION: An 84-year-old male, with severe aortic stenosis and high surgical risk, who was treated with TAVR...

BACKGROUND: Redo-transcatheter aortic valve replacement (TAVR) can pin the index transcatheter heart valve leaflets open leading to sinus sequestration and restricting coronary access. The impact of initial implant depth and commissural alignment on redo-TAVR feasibility is unclear. We sought to determine the feasibility of redo-TAVR and coronary access after SAPIEN 3 (S3) TAVR stratified by implant depth and commissural alignment. METHODS: Consecutive patients with native valve aortic stenosis were evaluated using multidetector computed tomography...

BACKGROUND: Ablation of accessory pathways (AP) is cornerstone for treatment of patients with Wolff-Parkinson-White Syndrome and manifestation of atrioventricular reentry tachycardia. Pulsed field ablation (PFA) is a new type of non-thermal form of energy source delivered to the underlying tissue via the ablation catheter and used for ablation of arrhythmic substrates. OBJECTIVE: We present the efficiency and long-term outcome of ablation of APs of different localizations using a focal pulsed electrical field...

BACKGROUND: Pregnancy-associated spontaneous coronary artery dissection (SCAD) and reversible cerebral vasoconstriction syndrome (RCVS) are rare conditions that may occur during pregnancy and the postpartum period. The coexistence of both diseases may pose a risk to patients, potentially resulting in a variety of complications and clinical manifestations. This is considered the first case of a patient who successfully recovered from a critical condition in the postpartum period, with contemporaneous SCAD and RCVS...

A young female patient presented with complaints of breathlessness and palpitations since 2 years. On clinical examination, there was a loud continuous murmur at the right sternal border.Transthoracic echocardiography and colour Doppler showed a tunnel-like structure originating from the aneurysmal right coronary sinus and opening into the right atrium with left to right shunt. Coronary angiography revealed a large tunnel beginning in right coronary sinus and terminating in the right atrium and right coronary artery (RCA) was seen originating from the tunnel...

BACKGROUND: Many patients with mild to moderately reduced left ventricular ejection fraction (LVEF) that require permanent pacemaker (PPM) implantation do not have a concurrent indication for implantable cardioverter-defibrillator (ICD) therapy. However, the risk of ventricular tachycardia/fibrillation (VT/VF) in this population is unknown. OBJECTIVE: To describe the risk of VT/VF following PPM implantation in patients with mild to moderately reduced LVEF. METHODS: Retrospective analysis was performed on 243 patients with LVEF between 35-49% who underwent PPM placement, and did not meet indications for an ICD...

UNLABELLED: The patient, a 68-year-old man, presented to our emergency room with chest pain, prompting an emergency cardiac catheterization due to elevated cardiac troponin-I levels. While no obvious coronary artery stenosis was found, there was evidence of apical ballooning wall motion in the left ventricle, leading to a diagnosis of takotsubo syndrome. Three months later, he occasionally experienced chest pain at rest, prompting us to conduct another cardiac catheterization. Left ventriculography showed normal contraction...

Coronary sinus (CS) anomalies, although infrequent, are increasingly diagnosed with advances in interventional procedures and imaging techniques. Most cases are asymptomatic and incidentally diagnosed. We present a case of an elderly male without comorbidities who presented with acute angina. Coronary catheterisation revealed a double-vessel disease, but incidentally, sequential angiograms captured contrast filling in the levophase of CS, revealing a giant CS. Primary percutaneous angioplasty of the right coronary artery was performed successfully...

BACKGROUND: Syphilis, owing to its natural course, can lead to long-term damage to the aortic valve, such as insufficiency and rarely stenosis, ostial coronary stenosis, and syphilitic aortitis. Cardiovascular involvement alongside neurological involvement dominates the prognosis. This should no longer be seen, thanks to awareness and prevention programmes, medical treatment, and antibiotics. CASE SUMMARY: We report a case of a 54-year-old chronic smoker with no previous history, admitted for respiratory distress amid an impaired general condition...

INTRODUCTION AND IMPORTANCE: Raghib syndrome is a rare congenital complication consisting of the termination of the left superior vena cava (LSVC) in the left atrium, an unroofed coronary sinus, and an atrial septal defect most often found in the posterior-inferior angle of the atrial septum. Both a right-to-left and a left-to-right intracardiac shunt exist. In most circumstances, they do not show any symptoms. PRESENTATION OF CASE: The patient presented with a persistent left superior vena cava draining into the left atrium, an unroofed coronary sinus, and a secondary atrial septal defect (ASD)...

INTRODUCTION: Supravalvular aortic stenosis (SVAS) is an uncommon congenital abnormality that presents with intimal thickening of the aortic media at the sinotubular junction. Given the congenital nature of the disease, patients usually become symptomatic in childhood. PRESENTATION OF CASE: A 48-year-old man developed symptomatic SVAS in middle age. A patch aortoplasty with a bovine pericardial patch was performed. His postoperative course was uneventful, and echocardiography revealed a significant decrease in peak velocity and pressure gradient...
