Silent stealth: painless aortic dissection masquerading as heart failure.

A male patient in his 50s presented to the emergency department with a three-day history of shortness of breath, New York Heart Association class IV, and oxygen desaturation. His physical examination revealed a large volume radial pulse with bibasal crepitation in the lungs and a soft diastolic murmur in the aortic area on auscultation of his heart. He was managed on the line of decompensated heart failure.

Super-response to renal denervation in treatment-resistant essential hypertension.

Renal denervation may be indicated in patients with treatment-resistant essential hypertension to decrease sympathetic nervous activity and optimise blood pressure. We present the case of a woman in her 50s with long-standing essential hypertension, a previous transient ischaemic attack, obesity and a family history of cardiovascular disease, who presented with persistent 24-hour ambulatory hypertension despite ongoing lifestyle modifications and being on five antihypertensive agents with no evidence of an alternative primary aetiology. She had intermittent palpitations and blurring of vision alongside evidence of left ventricular hypertrophy on a CT scan.

Renal Artery Denervation for the Management of Hypertension: Current Trends and Future Direction.

Renal artery denervation has re-emerged as a potential therapeutic option for patients with hypertension, especially those resistant to conventional pharmacotherapy. This comprehensive review explores the importance of careful patient selection, procedural techniques, clinical efficacy, safety considerations, and future directions of renal artery denervation in hypertension management. Drawing upon a wide range of available evidence, this review aims to provide a thorough understanding of the procedure and its role in contemporary hypertension treatment paradigms.

Drug-eluting balloon to treat immediate post-coronary artery bypass grafting ST-elevation myocardial infarction: a case report.

Background: Coronary artery bypass graft (CABG) surgery represents a major cardiovascular operation and may be associated with post-operative ST-elevation myocardial infarction (STEMI) due to graft failure. This is challenging to diagnose and treat as the implanted grafts may be prone to complications when treated percutaneously with drug-eluting stents.

Case Summary: A man in his 60 s underwent CABG and developed new persistent ST elevations of 2 mm in anterior leads with no significant chest pain, although, administered with intravenous opiates post-operatively.

Invasive management of non-ST elevation myocardial infarction (NSTEMI) in a patient with severe thrombocytopenia secondary to adult-onset immune thrombocytopenic purpura.

Managing patients with immune thrombocytopenic purpura (ITP) and thrombocytopenia is challenging when they present with acute coronary syndrome (ACS). They are at high risk of thrombotic events; however, antiplatelet medications may further lower the platelet count and predispose them to significant bleeding events, especially if undergoing percutaneous coronary intervention (PCI). We present a case of a man in his 70s, previously diagnosed with adult-onset ITP, admitted with ACS and severe thrombocytopenia.

Aortic plaque dehiscence caused by rotational atherectomy with Kokeshi phenomenon in a patient with aortic stenosis successfully treated with transcatheter aortic valve replacement.

Rotational atherectomy (RA) is an important interventional technique to facilitate effective percutaneous coronary intervention of severely calcified lesions. Despite the improved probability of better procedural outcomes during angioplasty, the use of RA is associated with an inherent risk of complications. Here, we present a case of a woman in her mid-90s with severe aortic stenosis (AS) who underwent RA facilitated angioplasty of the right coronary artery (RCA), with the procedure complicated by the Kokeshi phenomenon.

Management of Heparin-Induced Thrombocytopenia Using Plasmapharesis in Patients Undergoing HeartMate 3 Left Ventricular Assist Device.

Heparin-induced thrombocytopenia (HIT) type-2 is a rare, but life-threatening complication that presents a unique challenge in patients undergoing cardiac surgery. Patients that require cardiac surgery with HIT present a dilemma between intraoperative anticoagulation, perioperative bleeding risk, and perioperative thrombotic events. We describe a case series of four patients who developed HIT in their hospital course before HeartMate 3 (HM3) left ventricular assist device implantation.

Severe baffle leak after Takeuchi repair successfully treated with coronary bypass and percutaneous baffle closure: a case report.

Background: Anomalous left coronary artery from the pulmonary artery is a rare congenital abnormality that requires surgical correction.

Case Summary: We describe the case of a 33-year-old female with a history of anomalous left coronary artery of the pulmonary artery who presents with exertional angina. She underwent a Takeuchi repair that was complicated by a baffle leak.

In-Hospital Outcomes with Transfemoral Versus Transapical Access for Transcatheter Aortic Valve Replacement in Patients with Peripheral Arterial Disease.

Background: There is a paucity of data regarding outcomes with transfemoral (TF) versus transapical (TA) access for transcatheter aortic valve replacement (TAVR) in patients with peripheral artery disease (PAD).

Methods: We queried the national inpatient sample database (NIS) (2012-2013) to identify patients with PAD who underwent TAVR. We conducted a propensity matching analysis using 25 clinical variables to compare TF-TAVR versus TA-TAVR.

Ethnic and Gender Disparities in the Uptake of Transcatheter Aortic Valve Replacement in the United States.

Introduction: Little is known about ethnic and gender disparities for transcatheter aortic valve replacement (TAVR) procedures in the United States.

Methods: We queried the Nationwide Inpatient Sample (NIS) database (2011-2014) to identify patients who underwent TAVR. We described the temporal trends in the uptake of TAVR procedures among various ethnicities and genders.

Temporal Trends and Outcomes of Hospitalizations With Prinzmetal Angina: Perspectives From a National Database.

Background: Contemporary data regarding the temporal changes in prevalence and outcomes of hospitalizations with Prinzmetal angina are limited.

Methods: We queried the National Inpatient Sample Database for the years 2002-2015 to identify hospitalizations with Prinzmetal angina. We described the temporal trends and outcomes in patients with Prinzmetal angina.

Atrial myxoma presenting as acute ischaemic stroke and chronic right lower leg claudication.

A 48-year-old man presented with acute onset of left facial numbness, ataxic gait and double vision. He also complained of chronic right lower leg pain with acute onset a year prior to presentation. His vital signs were within normal limits.

Extra-adrenal pheochromocytoma presenting as inverse takotsubo-pattern cardiomyopathy treated with surgical resection.

Pheochromocytoma is a rare catecholamine-secreting tumour that is typically located in the adrenal medulla or along the sympathetic ganglia. The typical symptoms are episodic in nature and include tachycardia, sweating and headache. These tumours can present as transient, reversible cardiomyopathy similar to takotsubo cardiomyopathy (TCM).

prosthetic valve endocarditis with severe aortic regurgitation successfully treated with transcatheter aortic valve replacement.

We describe the case of a 69-year-old man with a history of bioprosthetic aortic valve replacement who presented with prosthetic valve endocarditis (PVE) complicated by severe aortic insufficiency with refractory cardiogenic shock despite antibiotic therapy. He was considered a prohibitive-risk surgical candidate due to co-morbid conditions and off-label valve-in-valve transcatheter aortic valve replacement (TAVR) was performed after detailed multidisciplinary evaluation. He recovered well without recurrent infection following completion of antibiotics and transthoracic echocardiogram at 12 months showed a normal functioning prosthetic valve.

Non-response to Cardiac Resynchronization Therapy.

Purpose Of Review: Cardiac resynchronization therapy (CRT) is an effective treatment option for therapy-refractory mild to severe heart failure (HF) patients with reduced ejection fraction and left ventricular (LV) conduction delay. Multiple clinical trials have shown that CRT improves cardiac function and overall quality of life, as well as reduces HF hospitalizations, health care costs, and mortality.

Recent Findings: Despite its effectiveness, the "non-response" rate to CRT is around 30%, remaining a major challenge that faces electrophysiologists and researchers.

Ambulatory Intra Aortic Balloon Pump in Advanced Heart Failure.

Cardiac transplantation is the gold standard treatment for patients with advanced congestive heart failure that is refractory to maximal medical therapy. However, donor heart availability remains the major limiting factor, resulting in a large number of patients waiting long periods of time before transplantation. As a result, mechanical circulatory support devices have been increasingly used as a 'bridge' in order to sustain organ function and stabilise haemodynamics while patients remain on the transplant waiting list or undergo left ventricular assist device surgery.

Hybrid Revascularization: A Review.

Hybrid coronary revascularization (HCR) combines surgical bypass with percutaneous coronary intervention (PCI) performed either during the same procedure or in a staged approach within 60 days. Coronary artery bypass grafting using the left internal mammary artery (LIMA) has shown excellent long-term patency with improved patient survival. It remains the gold standard treatment for the majority of patients with multivessel coronary artery disease.

Comparison of Long-Term Survival Benefits With Cardiac Resynchronization Therapy in Patients With Mild Heart Failure With Versus Without Diabetes Mellitus (from the Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy [MADIT-CRT]).

We have previously shown a reduction in HF events with cardiac resynchronization therapy with defibrillator (CRT-D) in patients with mild heart failure (HF) and diabetes mellitus (DM). It remains unknown whether HF remission in DM patients with CRT-D translates into reduced mortality. The effects of CRT-D versus an implantable cardioverter-defibrillator (ICD) alone to reduce long-term mortality were assessed in patients with left bundle branch block with DM (n = 386) and without DM (n = 982), enrolled in the Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy (MADIT-CRT).

Subclavian Artery Disease: Diagnosis and Therapy.

The diagnosis of brachiocephalic disease is often overlooked. Symptoms include arm claudication and vertebrobasilar insufficiency. In patients who have had the use of the internal mammary artery for coronary bypass surgery, the development of symptoms of myocardial ischemia should alert the clinician to the possibility of subclavian artery stenosis.

Comparison of Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting for Unprotected Left Main Coronary Artery Disease.

Coronary artery bypass grafting (CABG) decreases mortality in patients with significant left main (LM) coronary artery disease and for years remained the therapy of choice for patients with this ominous lesion. Advances in percutaneous coronary intervention (PCI) have enabled it to become an alternative to CABG. The results of observational registries and randomized comparisons have shown the safety and efficacy of PCI in appropriately selected patients with low or intermediate angiographic risk scores.

Aortic Stenosis: Pathophysiology, Diagnosis, and Therapy.

The incidence of aortic stenosis increases with age, affecting up to 10% of the population by the eighth decade. Once symptoms develop, aortic stenosis is rapidly fatal. Proper management requires an understanding of the physiology and criteria used to define disease severity.

Dilated aortic root and severe aortic regurgitation causing dilated cardiomyopathy in classic Ehlers-Danlos syndrome.

Ehlers-Danlos syndrome (EDS) is a group of heritable disorders characterised by vast clinical heterogeneity ranging from the classic constellation of symptoms including skin hyperextensibility, joint hypermobility and skin fragility to the exceedingly critical consequences of arterial rupture and visceral perforation. We describe the case of a 65-year-old male with a history of classic EDS who reported of dyspnoea on exertion, orthopnoea, fatigue and palpitations. He was found to have dilated cardiomyopathy with an ejection fraction of 35%, aortic root dilation and severe aortic valve regurgitation.

Penicillin-induced liver injury during treatment for ocular neurosyphilis.

A 51-year-old man, homosexual, recently diagnosed with ocular neurosyphilis, presented to the emergency room with a 1-day history of fevers and chills. His vital signs were significant for a temperature of 102.8°F and tachycardia of 125 bpm.
