Long-term outcomes of septal reduction for obstructive hypertrophic cardiomyopathy.

Background: Surgical myectomy and alcohol septal ablation (ASA) aim to decrease left ventricular outflow tract (LVOT) gradient in hypertrophic cardiomyopathy (HCM). Outcome of myectomy beyond 10 years has rarely been described. We describe 20 years of follow-up of surgical myectomy and 5 years of follow-up for ASA performed for obstructive HCM.

Most accurate definition of a high femoral artery puncture: aiming to better predict retroperitoneal hematoma in percutaneous coronary intervention.

Background: Retroperitoneal hematoma (RPH) increases morbidity and mortality in percutaneous coronary intervention (PCI). High femoral arteriotomy is an independent predictor of RPH, but the optimal angiographic criterion for defining a high puncture is unknown.

Methods: We retrospectively identified 557 consecutive PCI cases with femoral angiograms.
