Massive inferior wall aneurysm presenting with ventricular tachycardia and refractory cardiomyopathy requiring multiple interventions: A case report.

BACKGROUND: Inferior wall left ventricular aneurysms are rare, they develop after transmural myocardial infarction (MI) and may be associated with poorer prognosis. We present a unique case of a large aneurysm of the inferior wall complicated by ventricular tachycardia (VT) and requiring surgical resection and mitral valve replacement. CASE SUMMARY: A 59-year-old male was admitted for VT one month after he had a delayed presentation for an inferior ST-segment elevation MI and was discovered to have a large true inferior wall aneurysm on echocardiography and confirmed on coronary computed tomography (CT) angiography. Due to the sustained VT, concern for aneurysm expansion, and persistent heart failure symptoms, the patient was referred for surgical resection of the aneurysm with patch repair, mitral valve replacement, and automated implantable cardioverter defibrillator insertion with significant improvement in functional and clinical status. CONCLUSION: Inferior wall aneurysms are rare and require close monitoring to identify electrical or contractile sequelae. Coronary CT angiography can outline anatomic details and guide surgical intervention to ameliorate life-threatening complications and improve performance status.

Infolding of Self-Expandable Transcatheter Valve: A Complication that Needs Prompt Diagnosis During TAVR Procedure.

Infolding of self-expandable prosthetic valve is a possible complication of transcatheter aortic valve replacement (TAVR). A prompt diagnosis during the procedure before full deployment of the valve is extremely important to avoid potentially lethal consequences.

Patent Foramen Ovale-Induced Platypnea-Orthodeoxia Syndrome: A Case Report and Literature Review.

Platypnea-orthodeoxia syndrome (POS) is a rare condition characterized by dyspnea and hypoxia worsening in the upright position and relieved in the recumbent position. POS can result from anatomical or functional conditions that cause interatrial communication or deformity of the atrial septum. Investigations with imaging and cardiac catheterization can aid in the evaluation. In cases where POS is caused by intracardiac shunting without pulmonary hypertension, closure of the intracardiac shunt can be curative. We report a case of POS in a 54-year-old male who was treated successfully with percutaneous closure of a patent foramen ovale (PFO).
