A 78 year old female, diabetic, overweight and hypertensive presented with severe shortness of breath, orthopnea and paroxysmal nocturnal dyspnea

A 78 year old female, diabetic, overweight and hypertensive presented with severe shortness of breath, orthopnea and paroxysmal nocturnal dyspnea. She has limited mobility at home due to easy fatigue. On examination she was restless , tachycardiac with heart rate of 130 beats per minute, respiratory rate of 26 per minute and Blood Pressure of 110/60 mmHg. Auscultation revealed ejection systolic murmur at upper sternal border radiating to neck, S₃gallop and a displaced PMI on palpation. There were bilateral crackles in the chest. ECG showed ST depression in anterior precordial leads. Labs revealed a Troponin of 170, Creatinine of 2.0 mg/dl and BNP of 1617. Chest X-Ray revealed pulmonary edema. Echocardiography revealed EF of 35%, global hypokinesia, Aortic Valve Area of 0.8cm²and a mean gradient of 28 mmHg.

a) What are the treatment options available and which would you recommend for her?

b) Name recent trial conducted for such intermediate to high risk patients and its result interpretation?

c) What is the reason for low gradient, despite critical aortic stenosis?

d) What is the complication of TAVR?

Answers:

a.      Open surgical repair and TAVR, in this patient TAVR is recommended as he is at high surgical risk due to multiple comorbid conditions.

b.      SURTAVI Trial

c.       Paradoxical low-flow (PLF) aortic stenosis – LV dysfunction secondary to increased afterload imposed by critical aortic stenosis

d.      Complications:

Bleeding
Hematoma
Stroke
CHB requiring PPM insertion
Para-valvular leakObstruction of coronary ostea

Brugada ECG vs Incomplete Right Bundle Branch Block (iRBBB)

Brugada ECG vs Incomplete Right Bundle Branch Block (iRBBB) Why this differentiation matters Brugada pattern is a malignant channelopathy associated with sudden cardiac death, while incomplete RBBB is usually a benign conduction variant. Mislabeling Brugada as iRBBB can be fatal; overcalling iRBBB as Brugada can lead to unnecessary anxiety and ICD implantation. --- 1. Basic Definitions Brugada ECG Pattern Primary repolarization abnormality Genetic sodium-channel disorder Characteristic ST-segment elevation in V1–V3 Risk of ventricular fibrillation and sudden death Incomplete RBBB (iRBBB) Depolarization abnormality Delay in right ventricular conduction Common in healthy individuals Usually asymptomatic and benign --- 2. ECG Morphology: Side-by-Side Comparison QRS Duration Brugada: QRS usually <120 ms iRBBB: QRS <120 ms, but with RBBB morphology --- V1–V2 Pattern (Key Differentiator) Brugada Pseudo-RBBB appearance ST elevation ≥2 mm ST segment is coved or saddleback Terminal QRS bl...

𝘼𝙣𝙩𝙞𝙘𝙤𝙖𝙜𝙪𝙡𝙖𝙩𝙞𝙤𝙣 𝘼𝙛𝙩𝙚𝙧 𝙎𝙩𝙧𝙤𝙠𝙚 in Patient with AF and acute IS/TIA European Heart Association Guideline recommends: • 1 days after TIA • 3 days after mild stroke • 6 days after moderate stroke • 12 days after severe stroke Early anticoagulation can decrease a risk of recurrent stroke and embolic events but may increase a risk of secondary hemorrhagic transformation of brain infarcts. The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.

Acute Treatment of Hyperkalemia

Acute Treatment of Hyperkalemia – A Practical, Bedside-Oriented Guide Hyperkalemia is a potentially life-threatening electrolyte abnormality that demands prompt recognition and decisive management. The danger lies not only in the absolute potassium value but in its effects on cardiac conduction, which can rapidly progress to fatal arrhythmias. Acute treatment focuses on three parallel goals: stabilizing the cardiac membrane, shifting potassium into cells, and removing excess potassium from the body. Understanding this stepwise approach helps clinicians act quickly and rationally in emergency settings. Why Hyperkalemia Is Dangerous Potassium plays a key role in maintaining the resting membrane potential of cardiac myocytes. Elevated serum potassium reduces the transmembrane gradient, leading to slowed conduction, ECG changes, ventricular arrhythmias, and asystole. Importantly, ECG changes do not always correlate with potassium levels, so treatment decisions should be based on clinical c...
